This article explores the impact of patient demographics and socioeconomic status on surgical outcomes in endonasal endoscopic pituitary surgery. The study reviewed 187 patients who underwent this surgery between 2017 and 2019. The findings revealed that male patients were more likely to have larger tumors and higher comorbidity scores, while Hispanic patients had smaller tumors and lower comorbidity scores. Black patients experienced longer hospital stays, higher costs, and higher rates of readmission, regardless of income. These results suggest that racial health disparities are not solely due to socioeconomic status and emphasize the importance of considering social determinants of health in clinical practice.

- Abstract
Background: The extended endonasal approach has been utilized in the resection of anterior skull base lesions in the pediatric population. There are unique challenges to these patients in the post‐operative setting, including patient compliance with medical therapy and post‐operative debridements, and a smaller nasal airway that may increase propensity toward scarring. Our objective for this study is to evaluate the incidence of post‐operative radiographic inflammation in this patient population using the Lund‐Mackay (LM) score. Methods: A single‐center, retrospective review of pediatric patients undergoing endoscopic approach to the skull base between 2009 and 2021 was performed. Demographic and clinicopathologic data and pre‐ and post‐operative imaging were analyzed. One‐way ANOVA followed by Tukey multiple pairwise comparisons statistical tests were used to compare mean LM scores between groups. Results: Seventy‐two patients (52 males, 20 females) were identified with a median follow‐up of 27 months. All patients underwent an extended endonasal approach for resection of skull base lesions. The mean LM scores were compared between pre‐operative MRI, first post‐operative MRI > 30 days after surgery, and most recent post‐operative MRI. One‐way ANOVA was performed with significant differences noted between the groups (p < 0.001). Tukey multiple pairwise comparisons test was then performed and noted significant differences between the pre‐operative and first post‐operative LM (p < 0.0001) and the first post‐operative and most recent LM (p < 0.0001). There was no significant difference noted between the pre‐operative LM score and most recent LM score (p = 0.14). Conclusion: Despite concerns regarding possible subsequent development of chronic rhinosinusitis following endoscopic skull base surgery in pediatric patients, the current study suggests that transient radiographic evidence of sinus inflammation can be seen up to six months postoperatively, which appears to resolve by approximately two years after surgery.

Objective: To determine in-hospital costs associated with performing an EEA to anterior skull base pathology and to identify drivers of cost variability for patients undergoing endoscopic anterior skull base surgery. Methods: All endoscopic anterior skull base surgeries performed over a period from January 1st, 2015 to October 24th, 2017 were evaluated. The electronic medical record was reviewed for patient factors, tumor characteristics, and cost variables associated with each hospital stay and univariate analysis was performed using Stata software. Results: An EEA was associated with an average total in-hospital cost of $44 545. Compared to patients undergoing a transsphenoidal approach to pituitary tumor resection, EEA patients incurred higher in-hospital costs across all variables including a total cost increase of $15 921 (95% confidence interval $5720-26 122, P =.002). Univariate analysis of all endoscopic anterior skull base surgery patients showed a cost increase of $30 616 associated with post-operative cerebrospinal fluid (CSF) leak ($10 420-50 811, P =.004), $14 610 with post-operative diabetes insipidus (DI) ($4610-24 609, P =.004), and $11 522 with African-American patients relative to Caucasian patients ($3049-19 995, P =.008). Conclusions: Patients who undergo endoscopic EEA for resection of anterior skull base tumors typically incur greater in-hospital costs than patients undergoing a standard TSA. Post-operative complications such as CSF leak and DI, as well as ethnicity, are significant drivers of cost-variability. [ABSTRACT FROM AUTHOR]

Simple Summary: Inverted papillomas are benign sinonasal tumors that can recur or become cancerous. The mainstay of treatment is surgical resection. We summarize the biology of inverted papillomas and review surgical outcomes in an effort to define the current treatment strategy. Inverted papillomas (IP) are the most common sinonasal tumor with a tendency for recurrence, potential attachment to the orbit and skull base, and risk of malignant degeneration into squamous cell carcinoma (SCC). While the overall rate of recurrence has decreased with the widespread adoption of high-definition endoscopic optics and advanced surgical tools, there remain challenges in managing tumors that are multiply recurrent or involve vital neurovascular structures. Here, we review the state-of-the-art diagnostic tools for IP and IP-degenerated SCC, contemporary surgical management, and propose a surveillance protocol. [ABSTRACT FROM AUTHOR]

Background: Aspirin exacerbated respiratory disease (AERD) is an inflammatory condition that consists of eosinophilic asthma, chronic rhinosinusitis with nasal polyps, and respiratory reactions to cyclooxygenase-1 inhibitors. Aspirin therapy after aspirin desensitization (ATAD) is the most extensively studied treatment paradigm for AERD. Objective: The objective was to identify which time point of ATAD was most predictive of long-term outcomes as measured by the 22-item Sino-Nasal Outcome Test (SNOT-22). Methods: A retrospective chart review was conducted of patients at a single institution who underwent endoscopic sinus surgery, followed by ATAD, and had remained on ATAD for 2 consecutive years. SNOT-22 scores were recorded at predesensitization as well as at the 3-, 6-, 12-, and 24-month postdesensitization time points. The patients were separated into two cohorts at each of the data collection time points based on whether their SNOT-22 scores were < 20 (responders) or ≥ 20 (nonresponders). Responder status was compared between each time point and at 24-month postdesensitization. The odds ratios (OR) were then calculated between the two groups at each of the following time points: postsurgery/predesensitization, and 3-, 6-, and 12-month postdesensitization. Results: There were 70 patients who met the inclusion criteria of having 24-month postdesensitization SNOT-22 scores available. Responder status at 6 months after surgery had the most predictive OR 16.5 (95% confidence interval, 3.71–73.44) for long-term outcomes at 24 months. Conclusion: The SNOT-22 scores after 6 months of ATAD showed the greatest predictive value for long-term quality-of-life outcomes and, therefore, poor 6-month SNOT-22 scores could serve as a basis for consideration of alternative therapies.

Background: Aspirin-exacerbated respiratory disease (AERD) is optimally managed by endoscopic sinus surgery (ESS) followed by aspirin therapy after desensitization (ATAD). Most AERD quality of life (QOL) studies use the 22-item Sinonasal Outcomes Test (SNOT-22), which focuses predominantly on sinonasal outcomes. Objective: This study seeks to assess QOL outcomes in AERD patients after ESS and ATAD via the 12-item Short Form Survey (SF-12), a well-validated QOL measure for general health status of chronic conditions. Methods: Retrospective review of 112 AERD patients who underwent ESS followed by ATAD at our institution between 2016 and 2019. SF-12 was collected preoperatively, postoperatively/pre-AD, and serially post-AD (1–3, 4–6, 7–12, and >12 months). Optum® PRO CoRE software was used to compare data to national norms. ANOVA was performed comparing physical component summary (PCS), mental component summary (MCS) and eight health domains (physical functioning, role physical, general health, bodily pain, vitality, social functioning, role emotional, and mental health). Results: AERD patients showed improvement in PCS scores across all timepoints after ESS and ATAD (p = 0.004). When stratified by gender, women demonstrated an improvement in PCS scores (p = 0.004). Within the domains, there were significant improvements in social functioning (SF), role physical (RP), and bodily pain (BP) at all timepoints (SF: p = 0.006; RP: p = 0.005; BP: p < 0.001). Conclusions: AERD patients undergoing ESS and ATAD show improvement in physical QOL and 3 of the 8 health domains as measured by the SF-12. Future studies can use the SF-12 to study the impact of AERD treatment versus other chronic diseases and health demographics. [ABSTRACT FROM AUTHOR]

Background: Aspirin therapy and/or type 2 (T2) biologies are used in the management of aspirin-exacerbated respiratory disease (AERD). Objective: To identify the number of patients with AERD who tolerated aspirin therapy, yet due to persistent symptoms, incorporated T2 biologic management. Methods: A retrospective review was performed between July 2016 and June 2019. Patients with AERD and who underwent endoscopic sinus surgery (ESS), aspirin desensitization (AD), and at least 6 months of aspirin therapy (ATAD) after AD, and who remained biologic-naive up through this timepoint were included in the study. Introduction of a T2 biologic while on ATAD was the primary outcome. The secondary outcome was a change in a validated patient-reported outcome measure for chronic rhinosinusitis score between the postoperative predesensitization timepoint, and the 6-month postdesensitization timepoint, presented as means and compared by using the Student's t-test. Results: A total of 103 patients met inclusion criteria. Two patients (1.9%) ultimately supplemented ATAD with a T2 biologic. The mean outcomes measure test score after 6 months of ATAD for patients who received biologics was 40.5 versus 15 in those who did not receive biologics (p = 0.02). The mean differences between the postoperative predesensitization test score and the 6-month postdesensitization test score for patients who went on to receive biologics was an increase of 13 versus a decrease of 10 for those patients who did not receive biologics (p = 0.12). Conclusion: ESS, coupled with AD and ATAD, was successful in the long-term management of the majority of the patients with AERD, which rarely required the incorporation of T2 biologics. Patient questionnaires, such as outcomes measure test score, may identify aspirin therapy failures and help guide the practitioner in deciding when to introduce T2 biologics into the patient's treatment regimen.

Introduction Olfactory groove meningiomas (OGMs) are often associated with loss of smell following resection. Loss of smell has a measurable impact on quality of life. Smell preservation has been previously described in open approaches for early stage or unilateral OGMs. Evidence of smell preservation in endoscopic approaches is lacking. Design A multi-institutional retrospective review was performed on consecutive patients who underwent unilateral endoscopic endonasal resection of OGM. A gross total resection was achieved with preservation of the contralateral olfactory cleft and bulb. Olfactory function was assessed with a six-point olfactory symptom score and the Sniffin' Sticks 12-item smell identification test (SS-12). Contralateral olfactory bulb volume was measured on postoperative magnetic resonance imaging. Results Four patients (age 42.0 ± 7.5, 75% female) were assessed. Olfactory function was assessed at 21.8 ± 5.6 months following surgery. All patients reported some degree of smell preservation (75% described a slight/mild impairment in smell or better). Olfactory identification was preserved with an SS-12 score of 9 ± 1.4 (anosmia defined as ≤6). The olfactory bulb volume was calculated to be 47.4 ± 15.9 mm
3 (normal >40 mm3 ). Conclusion Smell preservation is possible following unilateral endoscopic endonasal resection of carefully selected OGM. [ABSTRACT FROM AUTHOR]- Published

CAVERNOUS hemangioma , *OPHTHALMIC artery , *OPTIC nerve , *MUSCLE tumors ,TUMOR surgery - Abstract
Background: Orbital cavernous hemangiomas (OCH) are the most common adult orbital tumor and represent an ideal index lesion for endonasal orbital tumor surgery. In order to standardize outcomes reporting, an anatomic‐based staging system was developed. Methods: An international, multidisciplinary panel of 23 experts in orbital tumor surgery was formed. A modified Delphi method was used to develop the cavernous hemangioma exclusively endonasal resection (CHEER) staging system with a total of 2 rounds being completed. Results: Tumors medial to a plane along the long axis of the optic nerve may be considered amenable for an exclusively endonasal resection. In select cases, tumors may extend inferolaterally if the tumor remains below a plane from the contralateral naris through the long axis of the optic nerve (ie, plane of resectability [POR]). This definition reached consensus with 91.3% of panelists in agreement. Five stages were designed based on increasing technical resection difficulty and potential for morbidity. Stages were based on the relationship of the tumor to the extraocular muscles, the inferomedial muscular trunk of the ophthalmic artery (IMT), and orbital foramina. Staging by anatomic location also reached consensus with 87.0% of panelists in agreement. Size was not included in the staging system due to the lack of agreement on the contribution of size to resection difficulty. Conclusion: Endoscopic orbital tumor surgery is a nascent field with a growing, yet heterogeneous, body of literature. The CHEER staging system is designed to facilitate international, high‐quality, standardized studies establishing the safety, efficacy, and outcomes of endonasal resection of OCH.

- Abstract
Objectives/hypothesis: Malignant sinonasal and skull base tumors are now being resected using an endoscopic technique, but there has been controversy regarding the oncologic safety of this approach. Various studies have compared the outcomes from endoscopic surgery to those from open techniques; however, all have been limited by substantial differences in the patient populations receiving each approach. In this study we compare outcomes of open and endoscopic techniques and use propensity score matching to control for these differences in the patient populations.Study Design: Retrospective cohort study including all patients > 18 years old receiving primary surgery for malignant sinonasal or skull base tumors at our institution from 2002 to 2013.Results: One hundred twenty-four patients met criteria; 82 received endoscopic-only surgery, and 42 had an open component to their approach. There was an 86% 3-year overall survival and a 74% disease-free survival. Without controlling for differences in the groups, the endoscopic patients fared significantly better in survival, recurrence rates, wound infections, and length of hospital stay. When using propensity score matching to account for patient comorbidities and tumor size, there were no significant differences in any outcomes except length of the hospital stay. A multivariate regression analysis yielded the same results.Conclusion: In this study, endoscopic surgery was shown to be a safe alternative to the open technique, even when controlling for the favorable patient and tumor characteristics in endoscopic patients. This is the first study to account for these differences with a rigorous statistical methodology.Level Of Evidence: 4. Laryngoscope, 126:1724-1729, 2016. [ABSTRACT FROM AUTHOR]- Published

Background: Endoscopic endonasal repair of cerebrospinal fluid (CSF) rhinorrhea secondary to idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri or benign intracranial hypertension, has varying success rates, from 25-87%, with minimal morbidity. However, often these series have a relatively short-term follow-up. Given the pathophysiology of IIH, long-term follow-up is necessary to identify true CSF leak recurrence rates. Our investigation aimed to evaluate long-term outcomes in endoscopically repaired CSF leaks. Methods: A retrospective chart review of all the patients with CSF rhinorrhea due to IIH who met inclusion criteria between 1996 and 2009. Outcome measures included the following: demographics, intracranial pressure, location of skull base defect, presence of encephalocele and/or meningoencephalocele, surgical repair technique, treatment with acetazolamide, whether a ventriculoperitoneal shunt was inserted, location of recurrence, history of meningitis or previous sinus surgery, and duration of follow-up. Results: Thirty-two patients with a total of 44 skull base defects were reviewed over a mean follow-up of 10.2 years. The mean body mass index and intracranial pressure were 36.8 kg/m
2 and 27.7 cm H2 O, respectively. Seven patients (18%) required revision surgery at the same site or a distant site. We found no statistical significance that identified the recurrence risk in the outcome measurements most likely due to our small failure rate. However, early recurrences were noted to recur at the same repair site, whereas late recurrences were noted to recur at a distant site along the skull base. Conclusion: IIH is an increasingly recognized entity treated by otorhinolaryngologists. We present the first long-term IIH CSF leak repair series. Long-term follow-up is necessary because delayed CSF leaks occur in this population. [ABSTRACT FROM AUTHOR]- Published

Purpose: Concha bullosa (CB) alters the intranasal anatomy and may influence the buffering of inhalant allergens and the inflammatory microenvironment central to chronic rhinosinusitis (CRS). By investigating the link between allergies and CB, we can examine this theoretical benefit, which has implications on the extent of resection in endoscopic sinus surgery.Methods: Forty-three adults treated between 2010 and March 2014 with chronic sinonasal symptoms were retrospectively analyzed by skin prick allergy testing, maxillofacial computed tomography scan, and Lund-Mackay score. x03C7;2 analysis and t tests were employed to determine statistical significance.Results: Subjects were divided into 30 positive cases and 13 pan-negative allergy controls. No difference in CB prevalence was observed between those with positive (70%) and those with negative (69.2%) allergy tests (p = 0.93). Furthermore, no association between CB and Lund-Mackay score was identified (p = 0.69). Overall, 83.3% of CB were located in the middle turbinate, 16.7% in the superior turbinate, and 20% occurred in the middle turbinate bilaterally.Conclusions: Although an enlarged, pneumatized turbinate could function as a physical barrier to inhalant allergens, documented allergies demonstrate no association with CB formation. Furthermore, this study finds no correlation between CB and radiographic evidence of CRS. [ABSTRACT FROM AUTHOR]- Published

Background: Open versus endonasal resection of orbital apex (OA) tumors is generally based on tumor size, location, and pathology. For endonasal resection, two- and four-handed techniques have been reported, but whether one technique is more optimal based on these tumor features has not been evaluated. Objective: To determine whether two- versus four-handed techniques result in better outcomes after endoscopic resection of OA tumors, and whether either technique is better suited for intra- versus extraconal location and for benign versus malignant pathology. Methods: A retrospective review of all expanded endonasal approaches for OA tumors was performed at a single institution from 2009 to 2013. A PubMed database search was also performed to review series published on endonasal OA tumor resection. Across all the cases reviewed, the following data were recorded: two- versus four-handed techniques, intra- versus extraconal tumor location, and benign versus malignant pathology. The relationship between these variables and resection extent was analyzed by the Fisher exact test. Postoperative visual status and complications were also reviewed. Results: Ten cases from the institution and 94 cases from 17 publications were reviewed. Both two- and four-handed techniques were used to resect extra- and intraconal OA tumors, for both benign and malignant pathology. Four-handed techniques included a purely endonasal approach and a combined endonasal-orbital approach. On univariate analysis, the strongest predictor of complete resection was benign pathology (p = 0.005). No significant difference was found between the extent of resection and a two- versus a four-handed technique. Visual status was improved or unchanged in 94% of cases, and other complications were rare. Conclusion: Benign tumors that involve the medial extraconal and posterior inferomedial intraconal OA can be treated by either two- or four-handed endonasal techniques. Selecting two- versus four-handed techniques and endonasal versus endonasal-orbital four-handed techniques depends mainly on surgeons' experience. Endonasal approaches for malignant OA tumors are less likely to result in complete resection. [ABSTRACT FROM AUTHOR]

Background Staphylococcus aureus and Pseudomonas aeruginosa are common culture isolates in chronic rhinosinusitis (CRS). We aimed to determine whether they were associated with different clinical factors of CRS. Methods Adult CRS patients who underwent functional endoscopic sinus surgery (FESS) between October 1, 2007 and December 31, 2011 were recruited. Patient demographics, Lund-Mackay computed tomography (CT) scores, 22-item Sino-Nasal Outcome Test (SNOT-22) scores, disease characteristics, and medication use were collected prior to FESS. Intraoperative culture was obtained in a standard manner. We compared patients with isolates of S. aureus or P. aeruginosa to patients with other culture results and no bacterial growth, respectively. Multivariate logistic regression was performed. Results A total of 376 patients met criteria; 104 patients (28%) had S. aureus, 32 (9%) had P. aeruginosa, and 10 patients (3%) had no bacterial growth. After adjusting for all clinical factors, compared to patients with positive culture other than S. aureus, patients with S. aureus had 1.9 times increased odds of having nasal polyps (odds ratio [OR] = 1.9; 95% confidence interval [CI], 1.0 to 3.3; p = 0.036); when compared to patients with positive culture other than P. aeruginosa, patients with P. aeruginosa had 7.8 times increased odds of having prior FESS (OR = 7.8; 95% CI, 2.1 to 28.9; p = 0.002) (91% vs 58%; p < 0.001) and 3.6 times increased odds of having diabetes with marginal significance (OR = 3.6; 95% CI, 1.0 to 13.2; p = 0.053). The sample size in the no bacterial growth group was too small to draw firm conclusions. Conclusion S. aureus was more common in CRS patients with nasal polyps, whereas P. aeruginosa was more common in CRS patients with prior FESS history and possibly diabetes. [ABSTRACT FROM AUTHOR]

Background Coagulase-negative Staphylococcus (CoNS) is commonly isolated from patients with chronic rhinosinusitis (CRS). However, the role of CoNS in CRS remains controversial. We aimed to determine the association between positive CoNS culture at functional endoscopic sinus surgery (FESS) and CRS severity. Methods Adult CRS patients who underwent FESS between October 1, 2007 to December 31, 2011 were recruited. Patient demographics, disease characteristics, medication use, Lund-Mackay computed tomography (CT) scores, and 22-item Sino-Nasal Outcome Test (SNOT-22) scores were collected at baseline before FESS. Intraoperative cultures were obtained in a standard manner. Patients were placed into 2 groups based on culture findings: patients with CoNS as the sole positive culture result and patients with all other positive culture results, including CoNS, as part of a polymicrobial culture. Results A total of 376 CRS patients met the criteria; 106 patients (28%) had CoNS as their only isolate, 260 (69%) had other positive cultures, and 10 (3%) had no bacterial growth. Compared to patients with other positive cultures, patients with the sole result of CoNS were significantly less likely to have a history of FESS (52% vs 65%, p = 0.019), nasal polyps (50% vs 65%, p = 0.006), and had a better Lund-Mackay CT score (11.95 vs 14.18, p = 0.020). After adjusting for all factors in the multiple logistic regression model, CoNS as the sole positive culture result was independently associated with having no history of FESS (odds ratio [OR] = 0.45; 95% confidence interval [CI], 0.22 to 0.94; p = 0.034). Conclusion Positive intraoperative CoNS cultures alone do not result in increased CRS disease burden by objective or subjective measures as compared to patients with other bacterial or polymicrobial culture isolates.

- Abstract
Objectives/Hypothesis Surgical treatment of inverted papilloma (IP) of the sphenoid sinus is complicated by close proximity to vital structures of the skull base. Identifying the site of tumor attachment and achieving complete removal can be challenging compared to IP at other sites. The objective of this study is to illustrate the clinical presentation, management, and risk factors for tumor recurrence for sphenoid IP. Study Design Retrospective study. Methods A multi-institutional, retrospective review of endoscopic resections of IP based within the sphenoid sinus was performed from 1996 to 2014. Demographic and tumor data, operative notes, complications, and recurrence rates were collected. Statistical analysis was performed to identify risk factors for tumor recurrence. Results Forty-eight patients (31 males, 17 females) were identified. Mean age was 57 years, with a median follow-up of 13.6 months (range 6.8-36). Rate of tumor recurrence was 14.6%, with median time to recurrence of 13.1 months. Patients with dysplasia/carcinoma in situ (CIS) had a 3.6 greater rate of recurrence (RR) compared to patients with no dysplasia, approaching significance (RR = 3.6; P = 0.08). Patients with IP attachment sites overlying the optic nerve or carotid artery had a 4.76 greater rate of recurrence compared to other sites (RR = 4.76; P = 0.073). Conclusion Sphenoid sinus IP is associated with a 14.6% rate of recurrence after surgery. Potential risk factors for tumor recurrence identified in this study include attachment sites over the optic nerve and carotid artery or evidence of dysplasia or CIS. Close follow-up in the postoperative period is essential for these patients to monitor for tumor recurrence. Level of Evidence 4. Laryngoscope, 125:544-548, 2015 [ABSTRACT FROM AUTHOR]

Background: Management of sinonasal malignancy (SNM) often includes surgical resection as part of the multimodality treatment. Treatment‐related surgical morbidity can occur, yet risk factors associated with complications in this population have not been sufficiently investigated. Methods: Adult patients with histologically confirmed SNM whose primary treatment included surgical resection were prospectively enrolled into an observational, multi‐institutional cohort study from 2015 to 2020. Sociodemographic, disease, and treatment data were collected. Complications assessed included cerebrospinal fluid leak, orbital injury, intracranial injury, diplopia, meningitis, osteoradionecrosis, hospitalization for neutropenia, and subsequent chronic rhinosinusitis. The surgical approach was categorized as endoscopic resection (ER) or open/combined resection (O/CR). Associations between factors and complications were analyzed using Student's t test, Fisher's exact test, and logistic regression modeling. Results: Overall, 142 patients met the inclusion criteria. Twenty‐three subjects had at least 1 complication (16.2%). On unadjusted analysis, adjuvant radiation therapy was associated with developing a complication (91.3% vs 65.5%, p = 0.013). Compared with the ER group (n = 98), the O/CR group (n = 44) had a greater percentage of higher T‐stage lesions (p = 0.004) and more frequently received adjuvant radiation (84.1% vs 64.4%, p = 0.017) and chemotherapy (50.0% vs 30.6%, p = 0.038). Complication rates were similar between the ER and O/CR groups without controlling for other factors. Regression analysis that retained certain factors showed O/CR was associated with increased odds of experiencing a complication (odds ratio, 3.34; 95% confidence interval, 1.06‐11.19). Conclusions: Prospective, multicenter evaluation of SNM treatment outcomes is feasible. Undergoing O/CR was associated with increased odds of developing a complication after accounting for radiation therapy. Further studies are warranted to build upon these findings.

Background: Postoperative nausea and vomiting (PONV) are adverse effects after surgery, which may increase the risk of complications. Aprepitant is a neurokinin‐1 receptor blocker and has been shown to reduce chemotherapy‐related nausea and vomiting and PONV. However, its role in endoscopic skull base surgery remains unclear. The purpose of this study was to evaluate the effect of aprepitant in reducing PONV in endoscopic transsphenoidal (TSA) pituitary surgery. Methods: A retrospective chart review between July 2021 and January 2023 of 127 consecutive patients who underwent TSA was performed at a tertiary academic institution. Patients were divided into 2 groups based on preoperative aprepitant use. Two groups were matched based on known risk factors of PONV (age, sex, nonsmoking, and history of PONV). The primary outcome was the incidence of PONV. Secondary outcome measures included the number of anti‐emetic use, length of stay, and postoperative cererebrospinal fluid (CSF) leak. Results: After matching, 48 patients were included in each group. The aprepitant group demonstrated a significantly lower incidence of vomiting than the non‐aprepitant group (2.1% vs 22.9%, p = 0.002). The number of nausea episodes and anti‐emetic use decreased with aprepitant use (p < 0.05). There was no difference in the incidence of nausea, length of stay, or postoperative CSF leak. Multivariate analysis demonstrated that aprepitant decreased the incidence of postoperative vomiting with odds ratio of 0.107. Conclusion: Aprepitant may serve as a useful preoperative treatment to reduce PONV in patients undergoing TSA. Further studies are needed to evaluate its impact in other arenas of endoscopic skull base surgery. [ABSTRACT FROM AUTHOR]

Background: Quality of life (QOL) for individuals with sinonasal malignancy (SNM) is significantly under‐studied, yet it is critical for counseling and may impact treatment. In this study we evaluated how patient, treatment, and disease factors impact sinonasal‐specific and generalized QOL using validated metrics in a large cohort over a 5‐year posttreatment time frame. Methods: Patients with SNM who underwent definitive treatment with curative intent were enrolled in a prospective, multisite, longitudinal observational study. QOL was assessed using the 22‐item Sino‐Nasal Outcome Test (SNOT‐22) and University of Washington Quality of Life Questionnaire (UWQOL) instruments at pretreatment baseline and multiple follow‐ups through 5 years posttreatment. Multivariable modeling was used to determine demographic, disease, and treatment factors associated with disease‐specific and generalized physical and social/emotional function QOL. Results: One hundred ninety‐four patients with SNM were analyzed. All QOL indices were impaired at pretreatment baseline and improved after treatment. SNOT‐22 scores improved 3 months and UWQOL scores improved 6 to 9 months posttreatment. Patients who underwent open compared with endoscopic tumor resection had worse generalized QOL (p < 0.001), adjusted for factors including T stage. Pterygopalatine fossa (PPF) involvement was associated with worse QOL (SNOT‐22, p < 0.001; UWQOL Physical dimension, p = 0.02). Adjuvant radiation was associated with worse disease‐specific QOL (p = 0.03). Neck dissection was associated with worse generalized physical function QOL (p = 0.01). Positive margins were associated with worse generalized social/emotional function QOL (p = 0.01). Conclusion: Disease‐specific and generalized QOL is impaired at baseline in patients with SNM and improves after treatment. Endoscopic resection is associated with better QOL. PPF involvement, adjuvant radiation, neck dissection, and positive margins were associated with worse QOL posttreatment. [ABSTRACT FROM AUTHOR]

Background: Non‐steroidal anti‐inflammatory drugs (NSAIDs) have emerged as an alternative to opioids for optimal postoperative pain management. However, the adoption of NSAIDs in sinonasal surgery has been impeded by a theoretical concern for postoperative bleeding. Our objective is to systematically review the efficacy and safety of NSAIDs for patients undergoing sinonasal surgery. Methods: MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, CINAHL, and the WHO International Clinical Trials Registry Platform were searched from inception to January 27, 2022. Randomized controlled trials (RCTs) and comparative observational studies in any language were considered. Screening, data extraction, and risk of bias assessment were performed in duplicate. Our outcomes were postoperative pain scores, requirement for rescue analgesia, and postoperative adverse events (epistaxis, nausea/vomiting). Results: Out of 4661 records, 15 RCTs (enrolling 1210 patients) and two observational studies were included. Following endoscopic sinus surgery, there was no difference in pain scores between NSAIDs and non‐NSAIDs groups (standardized mean differences [SMD] 0.44 units better, 95% CI –0.18 to 1.05). Following septorhinoplasty, NSAIDs decreased pain scores compared to non‐NSAID regimens (SMD 1.14 units better, 95% CI 0.61 to 1.67 units better). Overall, NSAIDs reduced the need for rescue medication with a relative risk (RR) of 0.45 (95% CI 0.24 to 0.84). In addition, NSAIDs decreased the risk of nausea with an RR of 0.62 (95% CI 0.42 to 0.91) and did not increase the risk of epistaxis (RR 0.72, 95% CI 0.23‐2.22). Conclusion: Among patients undergoing sinonasal surgery, NSAIDs are beneficial in postoperative pain management and avoidance of postoperative nausea without increasing the risk of postoperative epistaxis.

We implemented a streamlined care pathway for patients undergoing endoscopic transsphenoidal (TSA) pituitary surgery. Select patients are recovered in the postanesthesia care unit and transferred to a step-down unit for intermediate neurologic care (INCU), with clinicians trained to manage cerebrospinal fluid leak, diabetes insipidus (DI), and other complications. We evaluated all TSA surgeries performed at 1 academic medical center from 7th January, 2017 to 30th March, 2020, collecting patient factors, tumor characteristics, cost variables, and outcomes. The INCU pathway was implemented on 7th January 2018. Pathway patients were compared with nonpathway patients across the study period. Outcomes were assessed using multivariate regression, adjusting for patient and surgical characteristics, including intraoperative cerebrospinal fluid leak, postoperative DI, and tumor dimensions. One hundred eighty-seven patients were identified. Seventy-nine were on the INCU pathway. Mean age was 53.5 years. Most patients were male (66%), privately insured (62%), and white (66%). Mean total cost of admission was $27,276. Mean length of stay (LOS) was 3.97 days. Use of the INCU pathway was associated with total cost reduction of $6376.33 (P < 0.001, 95% confidence interval [CI]: $3698.21–$9054.45) and LOS reduction by 1.27 days (P = 0.008, 95% CI: 0.33–2.20). In-hospital costs were reduced across all domains, including $1964.87 in variable direct labor costs (P < 0.001, 95% CI: $1142.08–$2787.64) and $1206.52 in variable direct supply costs (P < 0.001, 95% CI: $762.54–$1650.51). Pathway patients were discharged earlier despite a higher rate of postoperative DI (25% vs. 11%, P = 0.011), with fewer readmissions (0% vs. 6%, P = 0.021). A streamlined care pathway following TSA surgery can reduce in-hospital costs and LOS without compromising patient outcomes. [ABSTRACT FROM AUTHOR]

Background: Postoperative management strategies for endoscopic skull base surgery (ESBS) vary widely because of limited evidence‐based guidance. Methods: The PubMed, EMBASE, and Cochrane databases were systematically reviewed from January 1990 through February 2022 to examine 18 postoperative considerations for ESBS. Nonhuman studies, articles written in a language other than English, and case reports were excluded. Studies were assessed for levels of evidence, and each topic's aggregate grade of evidence was evaluated. Results: A total of 74 studies reporting on 18 postoperative practices were reviewed. Postoperative pain management, prophylactic antibiotics, and lumbar drain use had the highest grades of evidence (B). The literature currently lacks high quality evidence for a majority of the reviewed ESBS precautions. There were no relevant studies to address postoperative urinary catheter use and medical intracranial pressure reduction. Conclusion: The evidence for postoperative ESBS precautions is heterogeneous, scarce, and generally of low quality. Although this review identified the best evidence available in the literature, it suggests the urgent need for more robust evidence. Therefore, additional high‐quality studies are needed in order to devise optimal postoperative ESBS protocols. [ABSTRACT FROM AUTHOR]

Background: Craniopharyngiomas have traditionally been treated via open transcranial approaches. More recent, endoscopic endonasal approaches have been increasingly used; however, there has been limited evaluation of long‐term outcomes for this approach. Methods: A retrospective review was performed to analyze patients with pediatric craniopharyngioma undergoing endonasal endoscopic resection from 2012 to 2020. Demographic information, clinicopathologic factors, and outcomes including follow‐up and recurrences were analyzed. Results: All 42 patients, with a mean age of 8.0 years, were included. The median follow‐up time was 49 months. Mean tumor diameter was 3.6 cm. All of the tumors had sellar and suprasellar components. The most common presenting symptoms were headaches (64.3%), visual changes (59.5%), and nausea/vomiting (38.1%). Most patients (73.3%) had resolution of their presenting symptoms by their first postoperative visit. Vision improved or remained normal in 69.0% of patients. Postoperatively, incidence of panhypopituitarism or diabetes insipidus developed in 89.7% and 77.8% of patients, respectively. The postoperative cerebrospinal fluid leak rate was 7.1%. The recurrence rate was 9.5%. Conclusion: Endoscopic endonasal resection for pediatric craniopharyngiomas can achieve high rates of resection with low rates of disease recurrence when compared with the outcomes of open transcranial resection reported in the literature. However, hypothalamic‐pituitary dysfunction remains a significant postoperative morbidity in both approaches. [ABSTRACT FROM AUTHOR]

Rathke cleft cysts (RCCs) arise from the development of the Rathke pouch. Recurrence is common after either drainage or cyst removal. The endoscopic endonasal approach (EEA) is increasingly utilized for the management of RCC. Various techniques have been described to try to reduce the rates of recurrence. We studied the effect of fenestration with a nasoseptal flap (NSF) on recurrence rates by comparing a cohort of patients undergoing this technique to a cohort of patients undergoing conventional drainage. Patients who underwent EEA for RCC between 2011 and 2020 were identified and divided into 2 cohorts: conventional fenestration versus fenestration with NSF. Surgical approach, reconstructive method, and recurrences were recorded. Primary end point was symptomatic or radiographic recurrence. 21 patients were identified undergoing EEA. An NSF was used to line the cyst cavity in 11 cases. Conventional fenestration without mucosal reconstruction was performed in the remaining 10 cases. In the cases without NSF, 5 (50%) developed recurrence requiring revision surgery, while there was only one recurrence in the NSF group (P < 0.05). In patients requiring revision, all had an NSF placed and none had a second recurrence of their RCC. NSF placement into a fenestrated RCC is useful to prevent cyst reaccumulation and reoperation. Typical fenestration carries an unacceptably high rate of recurrence. [ABSTRACT FROM AUTHOR]

Background: Aspirin‐exacerbated respiratory disease (AERD) is an aggressive respiratory tract inflammatory disorder manifesting as asthma, chronic rhinosinusitis with nasal polyposis, and a respiratory sensitivity to aspirin and nonsteroidal anti‐inflammatory drugs (NSAIDs). Corticosteroids, both systemic and topical/inhaled, are used to treat inflammation of the upper and lower airways. Our objective was to examine the potential impact of complete endoscopic sinus surgery (ESS) and aspirin desensitization (AD) on short‐term and long‐term corticosteroid use. Methods: For this pilot study, a retrospective chart review of all patients with AERD who underwent ESS followed by AD was performed. Daily prednisone use, average daily prednisone dose, and inhaled corticosteroid use were analyzed at the following time points: preoperative, postoperative/pre‐AD, and 2 to 3 months, 4 to 6 months, 7 to 12 months, and 13 to 24 months following AD. Results: A total of 125 patients underwent ESS followed by AD. Compared to preoperatively, patients who underwent ESS and AD were less likely to be on daily prednisone at all time points and upon long‐term follow‐up (32% preoperatively vs 10% at 13 to 24 months, McNemar's test = 9.00, p = 0.009). Average daily prednisone dose decreased from 10.6 ± 7.9 mg preoperatively to 3.8 ± 2.6 mg at 13 to 24 months following AD (Mann‐Whitney U; W = 122, p = 0.01). Similarly, high‐dose and medium‐dose inhaled corticosteroid use decreased from 18% to 7% and from 36% to 22% respectively (Pearson's chi‐square = 8.06, p = 0.05). Conclusion: In our AERD cohort who underwent ESS followed by AD, there was an observed decrease in overall systemic and topical/inhaled corticosteroid use. These findings can have implications for treatment given the potentially hazardous side effects of corticosteroid use. [ABSTRACT FROM AUTHOR]

Background: Patients undergoing endoscopic resection of neoplasms with both sinonasal and skull base involvement can develop chronic rhinosinusitis (CRS) after treatment and may occasionally benefit from additional endoscopic sinus surgery (ESS). We investigate risk factors and outcomes associated with revision ESS (rESS) after endoscopic skull‐base surgery (SBS) for neoplasms with combined sinonasal and skull base involvement. Methods: A retrospective review of patients with neoplasms with both sinonasal and skull base involvement who underwent endoscopic resection at a single tertiary care academic institution from 2004 through 2017 was performed. Eighty‐three patients were included. Main outcome measures included incidence and timing of revision surgery, Lund‐Mackay (LM) scores, and 22‐item Sino‐Nasal Outcome Test (SNOT‐22) scores. Results: rESS was performed in 21 (25%) cases, 15 (18%) of which were due to CRS. Time between initial resection and rESS was an average of 42 months (range, 6 to 142 months). Pre‐SBS and post‐SBS LM scores were not significantly different (5.0 vs 4.7, p = 0.640), although pre‐SBS and post‐SBS SNOT‐22 scores showed significant improvement (32.6 vs 24.5, p = 0.030). Malignant pathology correlated with need for rESS (odds ratio [OR] 5.07, p = 0.04), as well as treatment including chemotherapy (OR 5.10, p = 0.003) and radiation (OR 4.15, p = 0.013). Conclusion: A significant proportion of patients develop clinically significant sinusitis after endoscopic SBS for neoplasms with combined sinonasal and skull base involvement and may benefit from rESS. Intervention occurred, on average, 3.5 years after initial tumor resection. Malignant pathology, radiation therapy, and chemotherapy correlate with need for rESS. [ABSTRACT FROM AUTHOR]

TUMOR necrosis factors , *SINUSITIS , *ENDOSCOPIC surgery , *POLYPHOSPHATES - Abstract
Background: Chronic rhinosinusitis (CRS) is a frequently observed condition in patients with immunodeficiency secondary to tumor necrosis factor alpha inhibitors (TNFαis). The histologic features of CRS caused by TNFαis have yet to be determined and may have important implications in understanding the pathophysiology of the disease process. Methods: A structured histopathology report was used to analyze sinus tissue removed during functional endoscopic sinus surgery (FESS). These structured histopathology variables were compared among patients with CRS on TNFαi (CRSαi), CRS without nasal polyps (CRSsNP) patients, and CRS with nasal polyps (CRSwNP) patients. Results: Eighteen CRSαi, 91 CRSwNP, and 113 CRSsNP patients undergoing FESS were analyzed. Compared to CRSsNP, CRSαi patients exhibited increased mucosal ulceration (16.7% vs 0.9%, p < 0.008), increased fibrosis (100% vs 34.5%, p < 0.001), and increased presence of Charcot‐Leiden crystals (16.7% vs 0%, p < 0.002). Compared to CRSwNP, CRSαi patients demonstrated increased fibrosis (100% vs 54.9%, p < 0.001), decreased presence of subepithelial edema (44.4% vs 69.2% p < 0.043), decreased eosinophil aggregates (22.2% vs 47.3% p < 0.042), and fewer eosinophils per high‐power field (44.4% vs 73.6%, p < 0.017). Conclusion: CRSαi exhibits structured histopathology more similar to CRSsNP. In the appropriate clinical context, it may be reasonable that the medical regimen for these patients be focused on a more antineutrophilic, macrolide‐based approach. This study provides insight into the inflammatory environment of patients with CRSαi and may have implications for disease management. [ABSTRACT FROM AUTHOR]

Background: Chronic rhinosinusitis (CRS) is a common condition that affects people of all ages and negatively impacts quality of life. The goal of this study was to identify differences in outcomes by age following endoscopic sinus surgery (ESS) for CRS utilizing 22‐item Sino‐Nasal Outcome Test (SNOT‐22) scores. Methods: Data from 1252 adult CRS patients electing to undergo ESS (2007‐2018) were collected retrospectively. The median age of 50 years was used to divide the data into 2 groups for comparison of the impact of age on SNOT‐22 scores at 0, 3, and 6 months after surgery. Changes in SNOT‐22 scores were analyzed using a mixed models analysis. Results: After adjusting for gender, race, polyp status, and number of prior ESSs, patients younger than 50 years had a higher mean pre‐ESS SNOT‐22 score (44.0) compared to those of at least 50 years of age (38.9). Among patients younger than 50 years, SNOT‐22 scores declined by 20.7 points at 3 months post‐ESS and 16.1 points at 6 months post‐ESS. The rate of change between the dichotomized age groups was not significantly different at 3 and 6 months post‐ESS (p = 0.7952 and p = 0.1057, respectively). Conclusion: Both age groups showed significant and durable improvement in SNOT‐22 scores after ESS. Patients younger than 50 years of age have higher pre‐ESS SNOT‐22 scores, but converge to the same SNOT‐22 scores by 3 months post‐ESS. The rate of change of SNOT‐22 scores is not different between those younger than 50 years and those of at least 50 years. [ABSTRACT FROM AUTHOR]

Background: Endoscopic skull‐base surgery (ESBS) is employed in the management of diverse skull‐base pathologies. Paralleling the increased utilization of ESBS, the literature in this field has expanded rapidly. However, the rarity of these diseases, the inherent challenges of surgical studies, and the continued learning curve in ESBS have resulted in significant variability in the quality of the literature. To consolidate and critically appraise the available literature, experts in skull‐base surgery have produced the International Consensus Statement on Endoscopic Skull‐Base Surgery (ICAR:ESBS). Methods: Using previously described methodology, topics spanning the breadth of ESBS were identified and assigned a literature review, evidence‐based review or evidence‐based review with recommendations format. Subsequently, each topic was written and then reviewed by skull‐base surgeons in both neurosurgery and otolaryngology. Following this iterative review process, the ICAR:ESBS document was synthesized and reviewed by all authors for consensus. Results: The ICAR:ESBS document addresses the role of ESBS in primary cerebrospinal fluid (CSF) rhinorrhea, intradural tumors, benign skull‐base and orbital pathology, sinonasal malignancies, and clival lesions. Additionally, specific challenges in ESBS including endoscopic reconstruction and complication management were evaluated. Conclusion: A critical review of the literature in ESBS demonstrates at least the equivalency of ESBS with alternative approaches in pathologies such as CSF rhinorrhea and pituitary adenoma as well as improved reconstructive techniques in reducing CSF leaks. Evidence‐based recommendations are limited in other pathologies and these significant knowledge gaps call upon the skull‐base community to embrace these opportunities and collaboratively address these shortcomings.

Background Investigations into the distribution of sinus irrigations have been limited by labor-intensive methodologies that do not capture the full dynamics of irrigation flow. The purpose of this study was to validate the accuracy of a computational fluid dynamics (CFD) model for sinonasal irrigations through a cadaveric experiment. Methods Endoscopic sinus surgery was performed on 2 fresh cadavers to open all 8 sinuses, including a Draf III procedure for cadaver 1, and Draf IIb frontal sinusotomies for cadaver 2. Computed tomography maxillofacial scans were obtained preoperatively and postoperatively, from which CFD models were created. Blue-dyed saline in a 240-mL squeeze bottle was used to irrigate cadaver sinuses at 60 mL/second (120 mL per side, over 2 seconds). These parameters were replicated in CFD simulations. Endoscopes were placed through trephinations drilled through the anterior walls of the maxillary and frontal sinuses, and sphenoid roofs. Irrigation flow into the maxillary, frontal, and sphenoid sinuses was graded both ipsilateral and contralateral to the side of nasal irrigation, and then compared with the CFD simulations. Results In both cadavers, preoperative and postoperative irrigation flow into maxillary, frontal, and sphenoid sinuses matched extremely well when comparing the CFD models and cadaver endoscopic videos. For cadaver 1, there was 100% concordance between the CFD model and cadaver videos, and 83% concordance for cadaver 2. Conclusion This cadaveric experiment provided potential validation of the CFD model for simulating saline irrigation flow into the maxillary, frontal, and sphenoid sinuses before and after sinus surgery.
