Systemic sclerosis (SSc) is a heterogeneous, chronic connective tissue disease, characterized by skin fibrosis as well as vascular and visceral lesions. It can involve the lungs, heart, kidneys, gastrointestinal tract, and bones. The orofacial manifestations of SSc can cause functional, aesthetic, and social distress, resulting in significant psychological implications for the patients. In recent decades, fat grafting improved the aesthetic outcomes in terms of volume deficiency, contour asymmetry, and skin elasticity of the face thanks to the regenerative action of the stem cells contained within it. We describe five cases of a patient with SSc treated with fat grafting used to correct volume loss and facial elasticity of the lips and perioral region on the middle and lower third of the face. All the patients received regular postoperative checks at weeks 1 and 2. A multiple choice questionnaire was administered to assess the degree of tolerability of the procedure. The reliability of the questionnaire was evaluated by calculating the Cronbach alpha using the MedCalc Statistical Software version 20.113. The aim of our study is to describe three different types of fat grafting used to correct volume loss and restore facial elasticity of the lips and perioral region on the middle and lower third of the face.

The aim of this study was to investigate the correlation between pre-treatment inflammatory biomarkers and the post-operative depth of invasion (DOI) and worst pattern of invasion (WPOI) in early-stage oral tongue squamous cell carcinoma (OTSCC) by means of positive sentinel lymph node biopsy (SLNB). A retrospective analysis of patients affected by cN0 T1-T2 OTSCC who had undergone an SLNB at the National Cancer Institute of Naples was performed. The patients were studied using an evaluation of the pre-treatment neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammatory index (SII), and a histopathological analysis of the DOI and WPOI. The statistical analysis showed that among the prognostic biomarkers, the NLR was a significant predictor of high WPOI values (p = 0.002). The cut-off NLR value was 2.52 with a probability of developing a positive sentinel lymph node biopsy (SLNB) of 30.3%. In contrast, the DOI value was 5.20 with a probability of developing a positive SLNB of 31.82%. Regarding the WPOI, increasing the WPOI class increased the likelihood of a positive SLNB occurrence, and a positive significant correlation was found between the WPOI and SLNB (Csp = 0.342; p < 0.001). Pre-treatment NLR, together with post-surgical DOI and WPOI, can be a reliable predictor of occult neck metastasis in patients affected by early-stage OTSCC with a clinically negative neck. Further prospective studies with a larger series will be needed to confirm the results obtained and to better define the NLR, WPOI and DOI cut-off values in order for elective neck dissection to be recommended in relation to a clinically negative neck.

BackgroundThe long-term recovery rate for coronavirus disease 2019 related chemosensory disturbances has not yet been clarified.MethodsOlfactory and gustatory functions were assessed with psychophysical tests in patients in the first seven days from coronavirus disease 2019 onset and one, two, three and six months after the first evaluation.ResultsA total of 300 patients completed the study. The improvement in olfactory function was significant at the two-month follow up. At the end of the observation period, 27 per cent of the patients still experienced a persistent olfactory disturbance, including anosmia in 5 per cent of cases. As for taste, the improvement in the psychophysical scores was significant only between the baseline and the 30-day control. At the 6-month evaluation, 10 per cent of the patients presented with a persistent gustatory disturbance with an incidence of complete ageusia of 1 per cent.ConclusionSix months after the onset of coronavirus disease 2019, about 6 per cent of patients still had a severe persistent olfactory or gustatory disturbance.

Background: The reconstruction of midface skin defects represents a challenge for the head and neck surgeon due to the midface’s significant role in defining important facial traits. Due to the high complexity of the midface region, there is no possibility to use one definitive flap for all purposes. For moderate defects, the most common reconstructive techniques are represented by regional flaps. These flaps can be defined as donor tissue with a pedunculated axial blood supply not necessarily adjacent to the defect. The aim of this study is to highlight the more common surgical techniques adopted for midface reconstruction, providing a focus on each technique with its description and indications. Methods: A literature review was conducted using PubMed, an international database. The target of the research was to collect at least 10 different surgical techniques. Results: Twelve different techniques were selected and cataloged. The flaps included were the bilobed flap, rhomboid flap, facial-artery-based flaps (nasolabial flap, island composite nasal flap, retroangular flap), cervicofacial flap, paramedian forehead flap, frontal hairline island flap, keystone flap, Karapandzic flap, Abbè flap, and Mustardè flap. Conclusions: The study of the facial subunits, the location and size of the defect, the choice of the appropriate flap, and respect for the vascular pedicles are the key elements for optimal outcomes.

Cartilage grafts are well-known as being reliable in reconstructive surgery for craniofacial pathologies. The aim of this study is to describe a new technique which requires an incision smaller than 1.5 cm but is still effective for harvesting cartilage graft. Thirty-six patients who underwent costal cartilage harvesting for septorhinoplasty have been included in this study, admitted from January 2018 to December 2021. Out of 36 patients, 34 have not reported any major complications, and two cases were followed up for pneumothorax. There were no infections and no chest wall deformities. All patients reported minimal pain at the donor site. The Vancouver Scar Scale was used to evaluate the entity of the postoperative scarring phenomena. This scale total ranges from 0 (representing normal skin) to a maximum score of 13 (representing worst scar imaginable). The results were 1.53 SD ± 0.64 (on average) 1 week after the surgical procedure and 1.28 SD ± 0.45 (on average) at the 6 months follow-up. This minimally invasive method provided a valid and effective surgical technique for cartilage graft. Despite the limitations of the case series, it seems that this procedure might be comparable to other and well-established traditional procedures and could be even preferred when the minimal invasiveness is mandatory.

INTRODUCTION: Genioplasty is the gold standard technique to modify natural chin anatomy based on an inferior border osteotomy of the mandible enabling 3D-repositioning of the chin. Our “step-technique genioplasty” is a modified and improved surgical technique for advancement genioplasty in patients with elusive chin and vertical excess of the lower third. CASE PRESENTATION: We performed this technique on a 23-year-old female patient with a history of facial trauma that affected the morphology and aesthetics of the lower third. The surgery consisted of two osteotomy lines. The first osteotomy line was a monocortical osteotomy allowing to preserve the integrity of the lingual cortex. About 3 mm below, the second and complete bicortical osteotomy was performed to mobilize the chin segment. A bone fragment containing the vestibular cortex and medullary portion of the mandible was removed preserving the integrity of the lingual cortex and creating a bony step in mandibular symphysis. The osteotomized chin was advanced in the front of the bony step. DISCUSSION: Compared with known techniques, step-technique genioplasty allowed addressing the vertical chin excess not only at the level of the symphysis but also posteriorly with no over-projection of the chin and no deepening of the labiomental crease, common downsides in other approaches. CONCLUSION: The aesthetic outcome reflected the preoperative planning: we obtained a smoother transition between symphysis and horizontal branch of the mandible, just the right amount of anterior projection of the chin, greater stability, and predictability of the outcome with satisfying aesthetical results and no complications.

In 2003, Marx reported the first case of osteonecrosis of the jaw in 36 cases related to zoledronic acid or pamidronate. Painful bone exposure in the mandible or maxilla unresponsive to medical or surgical management was observed. In 2014, the American Association of Oral and Maxillofacial Surgeons proposed the term ‘medication-related osteonecrosis of the jaw’ (MRONJ). However, a non-exposed variant may also occur. MRONJ can lead to debilitating clinical sequelae with limited treatment options. We present the case of a 73-year-old woman with metastatic breast cancer and MRONJ of her mandible and maxilla following treatment with intravenous zoledronic acid and denosumab. Six months following dental extractions, she was referred to the Department of Oral and Maxillofacial Surgery for assessment of extensive necrosis of her maxilla and mandible. Extraoral draining sinuses were observed. A CT mandible showed cortical destruction with an ill-defined mixed sclerotic–lucent pattern in keeping with osteonecrosis. Due to her metastatic breast cancer, the extent of her necrosis and poor performance status, free flap reconstruction of her mandible was ruled out. She was treated conservatively.

We have read with interest the recent article by Lerner et al.,which analyzed the clinical features of parosmia following coronavirus disease 2019(COVID-19). Congratulating the authors for the quality of their study, we would like to discuss some important points regarding pathogenetic hypotheses and the epidemiological implications emerging from their results.

This study aimed to assess the metagenomic changes of soil bacterial community after constructing a crude oil flowline in Basilicata region, Italy. Soils identified a total of 56 taxa at the phylum level and 485 at the family level, with a different taxa distribution, especially in samples collected on 2014. Since microbiological diversity occurred in the soils collected after 2013 (the reference year), we performed a differential abundance analysis using DESeq2 by GAIA pipeline. In the forest area, 14 phyla and 126 families were differentially abundant (− 6.06 7.88) in 2014 compared to 2013. Nine families were differentially abundant in 2015, with logFC between − 3.16 and 4.66, while 20 families were significantly more abundant and 16 less abundant in 2016, with logFC between − 6.48 and 6.45. In the cultivated area, 33 phyla and 260 families showed differential abundance in 2014. In the next year (2015), 14 phyla were significantly more abundant and 19 less abundant, while 29 families were substantially more abundant and 139 less abundant, with fold changes ranging between − 5.67 and 4.01. In 2016, 33 phyla showed a significantly different abundance, as 14 were more abundant and 19 decreased, and 81 families showed a significantly increased amount with logFC between − 5.31 and 5.38. These results hypothesise that the analysed site is an altered soil where the development of particular bacterial groups attends to bioremediation processes, naturally occurring to restore optimal conditions.

Orbital floor Fractures are the most common fractures involving the facial skeleton and usually occurs after traumatic events. The reconstruction of the orbital floor can be performed with different biocompatible materials. The aim of our retrospective study is to analyze the short- and long-term outcomes of surgically treated patients based on the material used to repair the orbital floor.We enrolled 146 patients hospitalized for orbital floor fractures in the Maxillofacial Surgery Unit of the Federico II University of Naples from 1 to 2010 to July 2020. All the fractured orbital floors were reconstructed with non-resorbable (Titanium Mesh, SynPor, SuPor and MedPor implants) or resorbable (collagen membrane, bovinum pericardium membrane, autologous bone graft) materials.We utilized non-resorbable materials in 56% (82 cases) and resorbable implants in 44% (64 cases). An improvement of the preoperative symptomatology and an aesthetical good outcome was achieved in most cases.Data obtained supports that both resorbable and non-resorbable materials for orbital floor reconstruction are a safe and effective alternatives and offer satisfactory results in functional and aesthetic evaluations.

We have read with interest the recent article by Reis et al. which underlines the high frequency of persistent olfactory and gustatory dysfunctions in subjects infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Interstitial pneumonia is an important complication of COVID-19 and a reliable negative prognostic factor. This study aimed to analyze the correlation between olfactory psychophysical scores and severity of lung involvement detected by chest computed tomography in COVID-19 patients suspected of having interstitial pneumonia. We also evaluated whether severity of respiratory disease predicted recovery of olfactory dysfunction .

The appropriate surgical management of early-stage oral tongue squamous cell carcinoma (OTSCC) remains a debated topic. The aim of this study is to investigate the role of the pre-treatment neutrophil to lymphocyte ratio (NLR) and tumor depth of invasion (DOI) in predicting the presence of occult neck metastases in early-stage OTSCC. A retrospective analysis of patients affected by early-stage (cT1-T2 cN0) OTSCC who were submitted to elective neck dissection (END) was performed. Tumors were classified retrospectively according to the 8th TNM classification, the DOI was assessed on the pre-operative magnetic resonance imaging, and the pre-treatment NLR was calculated for each patient. A logistic regression model to estimate the probability π (x) of cervical metastases by studying the NLR and DOI was carried out. Next, the correlation between the two variables, the NLR and DOI, was preliminarily studied. A cohort of 110 patients was analyzed (mean age, 62 years old; male to female ratio 1.2:1). The patients were staged as cT1 in 53 cases and cT2 in 57 cases. A DOI greater than 5.4 mm and a NLR greater than 2.93 are associated with an increased risk of presenting occult cervical metastases. Furthermore, the variables NLR and DOI are linearly associated with a positive correlation, proved by Spearman's rank correlation coefficient rho of 0.64, with a unitary increase in the DOI of 1 mm directly associated with an increase of 0.47 in the NLR. The DOI and NLR can be effectively used to predict the occurrence of occult neck metastasis and therefore to plan an END in early-stage OTSCC.

Objectives To analyze the demographic data, surgical and adjuvant treatment data and the survival outcomes in adult patients affected by acinic cell carcinoma of the parotid gland (AciCC). Methods A retrospective multicenter analysis of patients treated for AciCC of the parotid gland from 2000 to 2021 was performed. Exclusion criteria were pediatric (0–18 years) patients, the absence of follow-up and patients with secondary metastatic disease to the parotid gland. Multivariable logistic regression was used to determine factors associated with survival. Results The study included 81 adult patients with AciCC of the parotid gland. The median age was 46.3 years (SD 15.81, range 19–84 years), with a gender female prevalence (F = 48, M = 33). The mean follow-up was 77.7 months (min 4–max 361, SD 72.46). The 5 years overall survival (OS) was 97.5%. The 5 years disease-free survival (DFS) was 60%. No statistical differences have been found in prognosis for age (p > 0.05). Conclusion This study did not find prognostic factor for poorest outcome. In contrast with the existing literature, our results showed how also high-grade tumours cannot be considered predictive of recurrence or aggressive behaviour.

COVID-19 related persistent olfactory disorders represent an unprecedented challenge

In recent years, the phenomenon of antibiotic resistance in hospitals, communities and the environment has increasingly grown, so antibiotic resistance has become an urgent problem that requires a decisive and global intervention. Incorrect/unnecessary use of antibiotics contributes to increase the ability of microorganisms to develop resistance faster and faster. Research efforts must, therefore, be made to ensure a future in which antibiotic drugs will still be useful in combating infectious diseases. The search for new antibacterial compounds is fundamental. In this study, the antimicrobial activity of the compounds was evaluated against selected bacterial strains from food and environmental matrices by using the Agar Well Diffusion Assay. A total of thirty-six Gram-positive and Gram-negative bacteria were employed to determine the action spectrum and the antimicrobial effectiveness of a small series of thiourea derivatives. Results showed that the highest activities were found for compounds 1 and 4. The important role of the alkyl chain length and/or guanidine moiety in the width of action spectrum was evidenced. Further studies will allow evaluating the efficacy of the inhibiting action and the molecular mechanisms underlying this activity in order to identify compounds capable of counteracting the phenomenon of antibiotic resistance and to identify possible future applications of these newly synthesized compounds that have shown a high bactericidal action potential.

Background: The aim of this study was to investigate how the systemic inflammation response index (SIRI), systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR), taken individually and combined, are associated with overall survival (OS) in patients surgically treated for malignant salivary gland tumors (MSGTs). Methods: A retrospective analysis of 74 cases following surgery at our department between January 2011 and June 2018 was performed. The Receiver Operating Characteristic (ROC) curve was used to calculate the optimal cutoff values for SII, SIRI, PLR, and NLR. Survival curves of different groups at 1–3–5 years were estimated using the Kaplan–Meier method. Results: The optimal thresholds with the highest sensitivity and specificity were 3.95 for NLR, 187.6 for PLR, 917.585 for SII, and 2.045 for SIRI. The ROC curves revealed that the best combination with AUC = 0.884 was SII + SIRI. The estimated 5-year OS probability in patients with SII+ SIRI scores of 0, 1, and 2 was 96%, 87.5% and 12.5%, respectively (p < 0.001). Conclusion: SII+ SIRI can independently predict the OS of patients after MSGT surgery. The prognostic score system based on SII+ SIRI may be good clinical practice as a reference for clinical decision-making.

Comments: We have some additional considerations about the recent published article by Perri et al [...]

Supplemental Digital Content is available in the text, Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has had a significant impact on people's behavior. The aim of this study has been to evaluate how the SARS-CoV-2 pandemic has impacted the incidence and the features of maxillofacial fractures presented at 6 Italian tertiary centers. Clinical records of all the patients diagnosed for facial fractures between February 23 and May 23, 2019 and 2020 were retrospectively reviewed. Any differences in patient number and characteristics and fracture etiology and site between the 2 groups were then statistically analyzed. There has been a 69.1% decrease in the number of incoming patients during the pandemic. The number of foreign patients has decreased significantly (23.3% versus 9.6%, P = 0.011) while the average age has increased (38.6 versus 45.6 years old, P = 0.01). Specific statistical significant differences for accidental falls (31.8% versus 50.1%, P = 0.005) and sports injuries (16.9% versus 1.4%, P

We present an extreme rare case of extramedullary nasal plasmacitoma that arise from nasal septum. The mass surgically removed was analyzed by a pathologist who diagnosed an extramedullary nasal plasmacytoma. The patient did not present systemic involvement. A short cycle of radiotherapy was performed after the surgery. At 9-month follow-up, the patient is recurrence free.

Background: The advantageous health effects of extracts from different types of plants have been known for centuries and the search for new natural extracts is very important at present. Methods: In this study, the antioxidant and the antimicrobial activities of Aesculus hippocastanum mother tincture (TM) against a range of foodborne bacteria were investigated to determine the major components and the action spectrum and the antimicrobial efficacy of the extract. Results: Results demonstrated a high antioxidant ability; total polyphenolic content was 506.8 ± 15.2mg GAE/100ml and the highest content was found for flavonoids. Moreover, TM demonstrated the antimicrobial activity against all tested bacteria and all Gram-negative bacteria were sensitive with an high antimicrobial activity. The inhibitory activity showed a moderate effect on the growth of 72.7% of strains in presence of different extract MIC. Conclusion: The synergistic actions of bioactive compounds detected in the TM might be on the basis of the antioxidant and biological activities observed. These results can be applied in the pharmaceutical field and also in food preservation, alternative medicine and natural therapies.

Simple Summary The purpose of this manuscript is to illustrate the difficulties associated with the treatment of the patient with recurrent metastatic SCCHN. This type of patient is very heterogeneous, including very different cases both as regards the natural history and the types of treatment to be used. The authors then illustrated the possible therapeutic options available and tried to propose the best strategies to be adapted to the individual case, based on the characteristics of the patient and the disease. The main conclusion of the following work is that the multidisciplinary approach is the winning weapon in any patient. Abstract Squamous cell carcinoma of the head and neck (SCCHN) is a complex group of malignancies, posing several challenges to treating physicians. Most patients are diagnosed with a locally advanced disease and treated with strategies integrating surgery, chemotherapy, and radiotherapy. About 50% of these patients will experience a recurrence of disease. Recurrent/metastatic SCCHN have poor prognosis with a median survival of about 12 months despite treatments. In the last years, the strategy to manage recurrent/metastatic SCCHN has profoundly evolved. Salvage treatments (surgery or re-irradiation) are commonly employed in patients suffering from locoregional recurrences and their role has gained more and more importance in the last years. Re-irradiation, using some particularly fractionating schedules, has the dual task of reducing the tumor mass and eliciting an immune response against cancer (abscopal effect). In this review, we will analyze the main systemic and/or locoregional strategies aimed at facing the recurrent/metastatic disease, underlining the enormous importance of the multidisciplinary approach in these types of patients.

Background: The first applications of computer-aided design/computer-aided manufacturing (CAD/CAM) in maxillofacial surgery date back to the 1980s. Since then, virtual surgical planning (VSP) has undergone significant development and is now routinely used in daily practice. Indeed, in an extraordinary period, such as that of the current COVID-19 pandemic, it offers a valuable tool in relation to the protection of healthcare workers. In this paper we provide a comprehensive summary of the clinical applications reported in the literature and review our experience using an in-house rapid prototyping technique in the field of maxillofacial surgery. methods: Our research was focused on reconstructive surgery, traumatology (especially in relation to orbital floor and zygomatic arch fractures), and COVID-19 masks. The first step was a radiographic study. Next, computed tomography (CT) scans were segmented in order to obtain a three-dimensional (3D) model. Finally, in the editing phase, through the use of specific software, a customized device for each patient was designed and printed. results: Four reconstructive procedures were performed with a perfect fitting of the surgical device produced by means of VSP. In nine orbital floor fracture cases a good overlapping of the mesh on the orbital floor was obtained. In sixteen zygomatic arch cases the post-operative CT scan showed an excellent fitting of the device and a correct fracture reduction. Regarding the COVID-19 period, six masks and shields produced proved to provide effective protection. conclusions: The timescale and costs required for the production of our &ldquo, home-made&rdquo, virtual design are low, which makes this method applicable to a large number of cases, for both ordinary and extraordinary activities.

Sinonasal inverting papilloma is a rare benign, locally aggressive tumour, arising from sinus and/or nasal fossa mucosa, with high recurrence rate, and risk of malignant transformation. This is a case of orbital invasive, lateral extending inverting papilloma approached via combined external and endoscopic surgery.

Background: The objective of this study was to investigate the efficacy and safety of early administration of oral corticosteroids (OC) or nasal corticosteroids (NC) as an add-on to olfactory training (OT) versus OT alone in patients with olfactory dysfunction (OD) related to coronavirus disease 2019 (COVID-19). Methods: Patients with a positive diagnosis of COVID-19 and OD were prospectively recruited from March 22 to December 15, 2020 from 4 European hospitals. Patients had confirmed OD on psychophysical testing. All patients undertook OT, with add-on 10 days of OC (group 1: OC + OT), or 1 month of NC (group 2: NC + OT) or olfactory training alone (group 3: OT). Olfactory evaluations (Sniffin’Sticks tests) were carried out at the time of inclusion, 1 and 2 months after the start of the therapeutic course. Results: A total of 152 hyposmic or anosmic patients completed the study. Group 1, 2 and 3 included 59, 22 and 71 patients, respectively and all patient groups were comparable regarding baseline Sniffin’Sticks tests. The median Sniffin’Sticks test values significantly improved from pre-to post-intervention in all groups. The increase of Sniffin’Sticks test values was higher in group 1 (OC + OT) compared with groups 2 and 3 (p < 0.001) at one month after treatment but did not remain so at 2 months. Groups 1, 2 and 3, respectively, presented parosmia in 20/71 (28.2%), 9/22 (40.9%) and 42/71 (59.2%) patients. This difference was statistically significant between group 1 and 3 (p < 0.001). There were no patients with a worsening of the disease or an increase of the severity of the COVID-19 symptoms. Conclusions: The use of OCs in patients with OD related to mild COVID-19 is generally well-tolerated without any case of deterioration of symptoms. OC is associated with greater improvement in psychophysical olfactory evaluations at 1-month post-treatment but there was no difference at 2 months. Parosmia may be reduced following treatment with OC and NC. On the basis of these preliminary results, it is possible to state that considering the 2 months efficacy of OC and NC with respect to the OT alone and the risk-benefit ratio, the benefit to start a specific treatment of COVID-19 related OD cannot be demonstrated and there is a need for a randomised controlled trial to assess this further., SCOPUS: ar.j, info:eu-repo/semantics/published

Simple Summary A large number of patients with head and neck squamous cell carcinoma (HNSCC) have an advanced-stage disease (stages III to IVB) that do not respond to therapy despite aggressive, site-specific multimodality therapy and most of them will develop disease recurrence. This is the description of a phase IIb randomized multicenter trial that involves the enrolment of 96 patients. The aim of the study is to verify whether electrochemotherapy performed with bleomycin of head and neck squamous cell carcinoma (HNSCC) relapses of the oral cavity and oropharynx is able to lead to an increase in the objective response rate in comparison with the systemic treatment with cetuximab + platinum-based therapy + 5-fluorouracil. The primary objective is to verify the objective response rate of patients in the control arm compared to the treatment arm. Abstract Background: A significant proportion of patients with head and neck squamous cell carcinoma (HNSCC) have advanced-stage disease (stages III to IVB) that do not respond to therapy despite aggressive, site-specific multimodality therapy. A great number of them will develop disease recurrence, with up to 60% risk of local failure and up to 30% risk of distant failure. Therapy can be very demanding for the patient especially when important anatomical structures are involved. For these reasons, therapies that preserve organ functionality in combination with effective local tumor control, like electrochemotherapy (ECT), are of great interest. Until few months ago, systemic cetuximab + platinum-based therapy + 5-fluorouracil represented the standard treatment for HNSCC relapses with a median overall survival of 10.1 months and an objective response rate of 36%. Recently the results of KEYNOTE-048 study were published and a new combination of monoclonal antibody named pembrolizumab and chemotherapy emerged as standard first line therapy of recurrent or metastatic tumor that overexpress tissue PDL-1 (Programmed Death 1 ligand). Nevertheless, a variable percentage from 10 to 15% of patients with recurrent/metastatic disease have a tumor that does not overexpress tissue PDL-1, and therefore, according to the results of the KEYNOTE-048 study, does not benefit from replacement of cetuximab with pembrolizumab. These patients will be treated with the “gold standard”: cetuximab, cisplatin/carboplatin and 5-fluorouracil. Aim: To verify whether electrochemotherapy performed with bleomycin of HNSCC relapses of the oral cavity and oropharynx (single relapse on T) is able to lead to an increase in the objective response rate in comparison with the systemic treatment with cetuximab + platinum-based therapy + 5-fluorouracil in patients with PDL-1 negative tumors. Methods: The phase IIb study involves the enrolment of 96 patients who meet the inclusion criteria (48 in the control arm and 48 in the treatment arm). The control arm involves the treatment of HNSCC with systemic treatment (cetuximab + platinum-based therapy + 5-fluorouracil). The treatment arm involves the ECT with bleomycin. The primary objective is to verify the objective response rate of patients in the control arm compared to the treatment arm.

Purpose A new member of the Coronaviridae family caused a worldwide pandemic emergency called Coronavirus disease 2019 (COVID-19). Health care workers who come into contact with the upper aero-digestive tract during diagnostic and therapeutic procedures, such as otolaryngologists, oral and maxillofacial surgeons, and head and neck surgeons, may undergo profound changes in their activities and are particularly at risk. We analysed the impact of COVID-19 on our oncological surgical activity. Methods To address the emergency and guarantee safety of patients referred to our Unit, reproducible guidelines were followed. Surgical activity data during COVID-19 were compared to previous years (2018 and 2019). Results From 21st February to 25th of May 113 surgical procedures were performed. The average of the two selected years (2018–2019) is 84.5, showing an increase of 34.5% of our activities (statistically significant, p = 0.0011). No patient showed perioperative or postoperative contagion. Conclusion Due to the conversion of regular Hospitals into COVID Centers, Cancer Centers may encounter an increased demand for procedures. Following strict guidelines, it seems possible to face surgical activity on cancer patients and respect standard procedures aimed at containing the spread of COVID-19 infection.

Major salivary gland malignancies are rare, constituting 1%-3% of head-neck tumours. The surgical management of the clinically negative neck (cN0) does not have a univocal consensus yet. We have carried out a retrospective study on 119 cases of malignant parotid tumours that were surgically treated between January 1999 and January 2014. Our aim was to analyse preoperative findings (cytotype, cTNM) and to correlate these with postoperative results (grading, histotype, occult neck metastasis) in patients with parotid tumours to obtain an appropriate indication for neck management. In cN0 patients with a T1, T2 low-grade cancer a wait-and-see approach is preferred. Instead, in cNO patients with high-grade or low-grade T3, T4 tumours an elective neck dissection (END) is always planned. Levels II, III and IV, at least, must be dissected. The decision to dissect level V or I depends on the location of the primary tumour. In the cN0 group 19 of 58 (32.7%) patients who underwent an END had occult metastases. In clinically positive neck (cN+) patients a Modified Radical Neck Dissection (MRND), at least, must be performed. The criteria to add adjuvant radiotherapy (PORT) include deep lobe parotid tumours, advanced lesions (T3-T4), microscopic (R2) or macroscopic (R1) residual disease after surgery, high grade tumours, perineural diffusion, lymph node metastasis, capsular rupture, and local recurrence after previous surgery. Kaplan-Meier analyses have shown a reduction in the overall survival (OS) from 100% to 91% and in disease-free survival (DFS) from 100% to 95.5% for the NO-PORT and PORT group, respectively. In our study, the cN0 pN+ patients had a higher degree of DFS compared to the cN+.

Low-grade intraductal carcinoma is a rare neoplasia with an excellent prognosis, previously classified as low-grade cribriform cystadenocarcinoma and low-grade salivary duct carcinoma. The tumor mainly occurs in the parotid gland and presents a ductal phenotype and an intraductal/intracystic growth pattern. It resembles intraductal breast lesions such as atypical ductal hyperplasia, papillary and cribriform ductal carcinoma in situ. Despite its infrequency, discriminating low-grade intraductal carcinoma from other salivary gland tumors is crucial, especially because of its favorable prognosis. A 74-year-old woman with a history of neurofibromatosis underwent a superficial parotidectomy to remove a sharply demarcated multi-cystic mass, diagnosed as category 4 at FNAC. The histological examination revealed a demarcated but unencapsulated lesion composed of a bigger cyst surrounded by several smaller cysts, lined by a monolayer or bilayer epithelium alternated with a cribriform proliferation, characterized by “Roman-bridges”, with occasional micro-papillae. A myoepithelial component, with a basal disposition, was present, confirmed by intense staining for protein p63 and SMA. Immunohistochemical stains showed intense, strong uniform positivity for pan-cytokeratin, protein S100, and SOX10. The Ki67 proliferation index was low (< 10%). A diagnosis of Low-grade Intraductal Carcinoma (LGIC) of the parotid was made. We performed a literature search in PUBMED for “Intraductal carcinoma”, “Low-grade Intraductal Carcinoma”, “Cribriform Cystadenocarcinoma”, “Salivary Duct Carcinoma”, and “Low-Grade Salivary Duct Carcinoma”. We selected 17 papers published between 1983 and 2020; the most affected anatomical site was the parotid gland (77/90), followed by minor salivary glands (6/90), the intraparotid lymph nodes (3/90) and the submandibular gland (4/90). Their main histopathological features are reported in the paper. Here we present a case report and a review of scientific literature on this topic to provide some essential diagnostic tools to discriminate this rare entity.

Background: The objective evaluation of the olfactory function of coronavirus disease 2019 patients is difficult because of logistical and operator-safety problems. For this reason, in the literature, the data obtained from psychophysical tests are few and based on small case series. Methods: A multicenter, cohort study conducted in seven European hospitals between March 22 and August 20, 2020. The Sniffin-Sticks test and the Connecticut Chemosensory Clinical Research Center orthonasal olfaction test were used to objectively evaluate the olfactory function. Results: This study included 774 patients, of these 481 (62.1%) presented olfactory dysfunction (OD): 280 were hyposmic and 201 were anosmic. There was a significant difference between self-reported anosmia/hyposmia and psychophysical test results (p = 0.006). Patients with gastroesophageal disorders reported a significantly higher probability of presenting hyposmia (OR 1.86, p = 0.015) and anosmia (OR 2.425, p &lt, 0.001). Fever, chest pain, and phlegm significantly increased the likelihood of having hyposmia but not anosmia or an olfactory disturbance. In contrast, patients with dyspnea, dysphonia, and severe-to-critical COVID-19 were significantly more likely to have no anosmia, while these symptoms had no effect on the risk of developing hyposmia or an OD. Conclusions: Psychophysical assessment represents a significantly more accurate assessment tool for olfactory function than patient self-reported clinical outcomes. Olfactory disturbances appear to be largely independent from the epidemiological and clinical characteristics of the patients. The non-association with rhinitis symptoms and the high prevalence as a presenting symptom make olfactory disturbances an important symptom in the differential diagnosis between COVID-19 and common flu.

BACKGROUND: The growing number of COVID-19 patients with long-lasting olfactory disorders makes it necessary to identify effective treatments that enhance the spontaneous recovery of olfactory function. METHODS: Multicentre randomised case-control study that involved 18 patients with COVID-19 related anosmia or severe hyposmia for more than 30 days. Nine patients were prescribed systemic prednisone and nasal irrigation with betamethasone, ambroxol and rinazine for 15 days. The other 9, untreated, patients were used as controls. The olfactory function was evaluated with CCCRC test at 20 and 40 days from the first evaluation. RESULTS: In the control group, a median olfactory score of 20 (IQR 30) was detected at baseline. At the 20-day control there was no significant improvement in olfactory function. The improvement in olfactory performance became significant at the 40-day follow-up compared to baseline scores [60 (IQR 60) versus 20 (IQR 30)]. In the treatment group, patients had a mean olfactory score of 10 (IQR 15) at initial control. At the 20-day control, a significant im-provement in the olfactory scores, compared to the baseline, was detected [70 (IQR 40) versus 10 (IQR 15)]. Olfactory function further improved at 40 days [median score 90 (IQR 50)]. Patients in the treatment group reported significantly higher improvements of the olfactory scores than the controls at both the 20-day [40 (IQR 45) versus 10 (IQR 15)] and 40-day [60 (IQR 40) versus 30 (IQR 25)] evaluations. CONCLUSIONS: Based on the results of this study, the mix of drugs including steroids could represent a useful specific therapy to reduce the prevalence of this long-term morbidity.

La sindrome da apnee notturne: correlazione con l’obesità e gestione del paziente obeso.La sindrome da apnee notturne è una malattia caratterizzata da ostruzione delle vie aeree superiori durante il sonno, abbastanza frequente nella popolazione generale, anche se sottovalutata. Russamenti, apnee notturne e ipersonnia diurna sono comuni in questi pazienti. L’obesità svolge un ruolo chiave: riduce le dimensioni e modifica la conformazione delle vie aeree superiori, oltre a prevenire l’espansione polmonare, con conseguente riduzione dei volumi polmonari. Le persone obese sono anche resistenti alla leptina, che stimola fisiologicamente la ventilazione; di conseguenza, questo provoca uno scarso risveglio durante l’apnea. La diagnosi si basa sulla combinazione di parametri clinici, come indice di apnea / ipopnea (AHI), anamnesi, valutazione clinica e Mallampati score. La prima indagine strumentale per identificare pazienti OSAHS è la polisonnografia seguita dalla sleep endoscopy. La terapia prevede in primo luogo la riduzione del peso corporeo, seguita dalla ventilazione a pressione positiva continua delle vie aeree (CPAP), che rimane ancora ad oggi il trattamento di scelta nella maggior parte dei pazienti, dispositivi di avanzamento mandibolare (MAD) e infine diversi approcci chirurgici. Tra le tecniche chirurgiche la faringoplastica (BRP), rappresenta la tecnica prescelta.Obstructive sleep apnoea/hypopnoea syndrome (OSAHS) is a disease characterised by upper airway obstruction during sleep, quite frequent in the general population, even if underestimated. Snoring, sleep apnoea and diurnal hypersomnia are common in these patients. Central obesity plays a key role: it reduces the size and changes the conformation of the upper airways, besides preventing lung expansion, with consequent reduction of lung volumes. Furthermore, obese people are also resistant to leptin, which physiologically stimulates ventilation; as a result, this causes scarce awakening during apnoea. OSAHS diagnosis is based on the combination of clinical parameters, such as apnoea/hypopnoea index (AHI), medical history, physical examination and Mallampati score. The first objective reference method to identify OSAHS is polysomnography followed by sleep endoscopy. Therapy provides in the first instance reduction of body weight, followed by continuous positive airway pressure (CPAP), which still remains the treatment of choice in most patients, mandibular advancement devices (MAD) and finally otolaryngology or maxillofacial surgery. Among surgical techniques, central is barbed reposition pharyngoplasty (BRP), used in the field of multilevel surgery.

From the first reports, ageusia and anosmia appear to be frequent clinical features in coronavirus disease 19 (COVID-19) patients. We have performed a survey of the literature, analyzing the possible causes of these chemosensory alterations, which may be useful as a starting point for specific further studies.

Background The anatomical complexity of the oropharynx and the difficulty in reaching its distal portion have always conditioned the surgical accessibility. Robotic surgery represents an excellent alternative in the treatment of cervico-facial oncological diseases. Methods This series comprises all patients managed for head and neck cancer by Trans Oral Robotic Surgery TORS. The staging assessment, including neck ultrasound and total body PET/CT scan, was performed in each patient according to the TNM classification. All charts were recorded with the following data: name and surname, age, gender, date of surgery intra or post-operative hemorragia, tumor site, histology, TNM stage, robot set-up time, tumor resection time, whether or not tracheotomy was performed, whether or not neck dissection was performed, insertion of a nasogastric tube or gastrostomy, time to resumption of oral feeding, surgical margins, mean length of hospital stay, adjuvant treatment and follow-up. Results From February 2013 to February 2018, TORS was performed in 67 consecutive patients affected by head and neck tumours. We divided, our sample, in 3 subsites: supraglottic larynx, parapharyngeal space and oropharynx. Pathology reports confimed malignancy in 44 cases: 8 cases lymphomas, 36 cases of Squamous cell carcinoma (SCC), 5 cases of benign salivary glands tumors and 18 miscellaneous cases. Neck dissection was performed in 12 cases. Tracheotomy was perfomed in 3/67 cases for respiratory failures. A nasogastric tube was inserted at the end of the surgical procedure in 21 patients. The mean length of hospital stay was 10 days . Major complications included post-operative bleeding in 3 patients, 1 exitus for massive bleeding 20 days post-surgery and 1 respiratory failure treated with tracheotomy and monitoring in the Intensive Care Unit (ICU) for 3 days. Conclusions Robotic surgery has been considered a valid alternative to traditional open treatment in many specializations with the advantages of an endoscopic procedure, with the same oncological and functional results and with fewer complications. The advantages of this type of surgical technique have been discussed, it is mandatory to focus on the indications and contraindications.

Background Objective data on chemosensitive disorders during COVID‐19 are lacking in the Literature. Methods Multicenter cohort study that involved four Italian hospitals. Three hundred and forty‐five COVID‐19 patients underwent objective chemosensitive evaluation. Results Chemosensitive disorders self‐reported by 256 patients (74.2%) but the 30.1% of the 89 patients who did not report dysfunctions proved objectively hyposmic. Twenty‐five percentage of patients were seen serious long‐lasting complaints. All asymptomatic patients had a slight lowering of the olfactory threshold. No significant correlations were found between the presence and severity of chemosensitive disorders and the severity of the clinical course. On the contrary, there is a significant correlation between the duration of the olfactory and gustatory symptoms and the development of severe COVID‐19. Conclusions Patients under‐report the frequency of chemosensitive disorders. Contrary to recent reports, such objective testing refutes the proposal that the presence of olfactory and gustatory dysfunction may predict a milder course, but instead suggests that those with more severe disease neglect such symptoms in the setting of severe respiratory disease.

Background Chemosensitive disorders are very frequent in the early stages of COVID‐19 and in paucisymptomatic cases. These patients are typically placed in home quarantine. This study has the aim of validating a new olfactory and gustatory objective evaluation test in these patients. Methods Thirty‐three home‐quarantined COVID‐19 patients have undergone a self‐administered chemosensitive test the day before the control swab. On this occasion, the patients underwent operator‐administered already validated tests. The results were finally compared. Results The differences between the results of the two tests were not significant for both the olfaction (P =.201) and the taste (P =.180). Conclusion The olfactory and gustatory evaluation by self‐administered test can be considered a valid tool, fundamental for obtaining objective qualitative and quantitative data on the extent of chemosensitive disorders in home‐quarantined COVID‐19 patients.

Objective: Use of cyanoacrylate glue in facial plastic surgery is still controversial due to the absence of long-term follow up showing the results. Aim of our study is comparing the long-term outcomes of N-butyl-cyanoacrylate + Metacryloxysulfolane versus traditional sutures in rhinoplasty. Methods: Prospective comparative study. One hundred forty-two patients affected by ptotic nasal tip were included and randomized in two groups. In group A, the surgeon fixed the graft by using the glue and suture and in group B by using the traditional suture only. The following data were collected and compared by statistical analysis: nasolabial angle before and after surgery, dimensions of the graft, duration time (in minutes) for graft application during the surgery, number of sutures applied to fix the graft, presence of post-surgery negative outcomes. Results: All patients statistically improved their nasolabial angle after surgery (ANOVA: P < .0001) without statistically significant differences between the two groups both at short and long follow-up (χ: P = 1 and P = .9 respectively). A statistically significant difference in graft fixation time ( P < .00001) and number of sutures (t: P < .00001) used was observed between the two groups. No statistically significant difference was observed in prevalence of infection after surgery. Conclusion: N-butyl-cyanoacrylate + Metacryloxysulfolane could be a valid tool to reduce the necessary number of sutures and to reduce the time required for graft fixation graft fixation with consistent results in long-term follow-up.

Syngnathia is a congenital bony fusion of the mandible to maxilla involving the pediatric age. it is a rare condition that may comprise soft tissue or hard tissues. according to the literature, to our knowledge, 29 cases have been reported during childhood. This clinical condition is usually discovered immediately after birth, since the child is not able to open the mouth, and is unable to feed himself adequately. generally the surgical treatment consists of multiple procedures to release bony fusion, or debride adhesions during the first few days of life. When the lock involves only the soft tissue, the treatment consists in removal the mucosal synechia, by performing an intraoral approach. To our knowledge, herein we describe the first case of unilateral syngnathia in adulthood. A 27-year-old African male was referred to our Department of Maxillo-Facial Surgery of the Federico ii university of Naples in January 2008. The patient reported to have been victim of a direct trauma to the face as a result of an assault when he was child, during the second civil war in Sudan. he was hit with a blunt instrument on the right maxillo-zygomatic region. in conclusion, as far as we know, this is the older patient affected by syngnathia with a suspicion of traumatic etiology, and none of the patients reported in the literature had a traumatic etiology.

Reconstruction of scalp defects can be performed with local flaps for medium to large defects (2–25 cm2) and microvascular free flaps for extensive full-thickness scalp reconstruction greater than 25 cm2. Doppler flowmetry with its ability to exactly mark the course of arteries on the overlying skin, is a useful tool for the surgical planning of large local flaps. In our retrospective study conducted on 38 patients (all patients had malignancies or post-traumatic scalp defects), consisting of 39 total surgical procedures, we studied the impact of doppler ultrasonic flowmetry in the surgical planning for pedicled flaps in extensive full-thickness scalp reconstruction (>25 cm2) by evaluating overall flap survival rate. Nine different types of local flaps were employed in the scalp reconstruction: Superficial temporal artery (STA) pedicled rotation flap, STA pedicled transposition flap, STA islanded flap, bipedicled STA flap, bipedicled fronto-occipital flap, Supraorbital/Supratrochlear artery rotation flap, Supraorbital/Supratrochlear artery transposition flap, Occipital artery (OA) pedicled rotation flap, OA pedicled transposition flap. Before each surgical procedure a hand held doppler Huntleigh Diagnostic flowmeter with a 8 MHz probe was used to identify and follow the course of the arteries. Flap survival rate was 100%. No postoperative complications related to the flap were reported, while in two patients a partial skin graft failure occurred.

BackgroundAn objective evaluation of coronavirus disease 2019 in the first days of infection is almost impossible, as affected individuals are generally in home quarantine, and there is limited accessibility for the operator who should perform the test. To overcome this limitation, a recently validated psychophysical self-administered test was used, which can be performed remotely in the assessment of early-stage coronavirus disease 2019 patients.MethodsOlfactory and gustatory functions were objectively assessed in 300 patients in the first 7 days from coronavirus disease 2019 symptom onset.ResultsSeventy per cent of the patients presented olfactory and/or gustatory disorders. The dysfunctions detected were mainly complete anosmia (47 per cent) or ageusia (38 per cent). A significant correlation was found between taste dysfunction and female gender (odds ratio = 1.936, p = 0.014) and fever (odds ratio = 2.132, p = 0.003).ConclusionThe psychophysical evaluation protocol proposed is an effective tool for the fast and objective evaluation of patients in the early stages of coronavirus disease 2019. Chemosensitive disorders have been confirmed to be frequent and early symptoms of the coronavirus infection, and, in a significant number of cases, they are the first or only manifestation of coronavirus disease 2019.
