Coronary artery anomalies are being more frequently diagnosed these days both because increasing numbers of patients are undergoing diagnostic studies and because advanced radiographic imaging methods are now commonly available. An isolated single coronary artery giving rise to the main coronary branches is a rare congenital anomaly. In this report we present a patient with a solitary coronary ostium, with both the left and right coronary artery systems arising from it, and then following their usual courses. This case was diagnosed incidentally during conventional angiography.

Introduction: Both CO2 transoral laser microsurgery (CO2 TOLMS) and radiotherapy (RT) are standard of care in early glottic carcinoma. However, previous studies focus on voice outcomes rather than swallowing outcomes. This study aimed to compare the late post-treatment effects of CO2 TOLMS and RT treatment on swallowing function in T1 glottic carcinoma., Methods: Forty patients (20 CO2 TOLMS and 20 RT) with T1 glottic cancer between May 2015 and January 2019 were included. Certain types of foods triggering dysphagia, any difficulties in bolus control, need to clean the throat, the sensation of lumping in the throat, choking, cough and xerostomia were questioned. Also, functional oral intake scale (FOIS), functional outcome swallowing scale (FOSS), Eating Assessment Tool-10 test (EAT-10) and flexible fiberoptic endoscopic examination of swallowing (FEES) findings were assessed., Results: CO2 TOLMS patients performed significantly better than the RT group regarding penetration and aspiration with 10 and 20 mL water according to the Penetration and Aspiration Scale (P < .05). The mean EAT-10 Score was found 0 in the CO2 TOLMS group, and 3.20 ± 3.24 in the RT group (P < .05) (lower score indicates a better outcome). According to the Yale Pharyngeal Residue Severity Scale for vallecula, there was no statistically significant difference in vallecular residue between the groups (P > .05). A significantly lesser residue in piriform sinus was detected in the CO2 TOLMS group compared to the RT group with 5 mL and 10 mL water, 5 mL and 20 mL honey consistency food and yogurt according to Yale Pharyngeal Residue Severity Scale (P < .05)., Conclusion: It is suggested that in the long term, CO2 TOLMS is more advantageous regarding swallowing function in the treatment of T1 glottic cancer., (© 2020 John Wiley & Sons Ltd.)

Background: Retrospective analysis of extracapsular dissection (ECD) and superficial parotidectomy (SP). Aims/objectives: Comparing the outcomes of ECD and SP in surgery of benign parotid masses. Material and methods: Total of 136 patients included in the study. The inclusion criteria were pathologically proven benign FNA biopsy, lack of deep lobe invasion and single tumour diameter lower than 4 cm, absence of radiologically and clinically malignant lesion and facial paralysis at the time of diagnosis. Objectives: Drain volumes and seroma presence, clinical evaluation of face nerve function; signs of infective complications were collected from patients' clinic chart. Complications and recurrence rates were obtained from follow-up forms. Results: The mean follow-up period was 42.53 ± 14.88 months. In SP group, three patients with disease recurrence were found, 8 (10.2%) had early facial nerve paralysis (grade 2 and 3) and 11 (14.1%) had Frey's syndrome. No postoperative complication, early facial paralysis and recurrence were observed in ECD group. Conclusion and significance: ECD procedure was found to be as successful as SP in the selected patient group in approach to the pathologically proven and single benign parotid masses with similar recurrence and lower complication rates compared to the SP.

In this study we aimed to examine the effects on wound healing and nerve regeneration of human and rat amniotic membrane wraps around primary epineural anastomosis areas after a peripheral nerve transection injury in rats. We randomized 25 male adult rats with induced peripheral transection injuries into 5 groups (control, transection injury, primary epineural anastomosis [PEA] after injury, PEA with a human amniotic membrane [hAM] wrap, and PEA with a rat amniotic membrane [rAM] wrap groups and treated their injuries accordingly. We took tissue samples from the anastomosis regions, 12 weeks after the experiment, and analyzed them stereologically and ultrastructurally. We performed a statistical analysis with the recovered stereological counts and the measurement data. Our results showed that the use of amniotic membranes for allografts (between same species) instead of xenografts (between different species), along with microsurgery, provides a suitable microenvironment during the healing process with less immunological reaction on the injured site and supports axonal regeneration., (Copyright © 2018 Elsevier Ltd.

In this study, we compared the bone-healing effects of the local application of platelet-rich fibrin (PRF) and hyaluronic acid (HA) to bilateral tibial fractures in rats. Twenty-three adult male Sprague-Dawley rats were used. Twenty-two animals were randomly allocated to a control group (n = 6) and 2 study groups: PRF (n = 8) and HA (n = 8). The 23rd rat was used as a donor to obtain PRF. Each group was divided into 2 subgroups for histomorphometric and radiologic assessments at 2 and 6 weeks. Foreign body reaction, necrosis, inflammation, new bone formation, and fibrosis were investigated as bone healing parameters in terms of histopathologic analysis. The difference between the groups for these parameters was evaluated. The radiologic evaluation was performed by comparing the 3-dimensional reconstruction images of the fracture sites between the study and control groups. Histomorphometric evaluation showed that at 2 weeks postoperatively, the control group showed lesser bone formation (26.1 ± 6.6%) when compared to the study (HA: 54.7 ± 9.7%; PRF: 75.3 ± 19.2%) groups and PRF group showed highest total ossification. At 6 weeks postoperatively the PRF group showed lesser total ossification (50.7 ± 28.2%) when compared to control (76.3 ± 21.7%) and HA group. The HA (88.8 ± 13.3%) showed highest total ossification. In the control group, fibrosis was more prominent at week 6, whereas in the HA and PRF groups the amount of ossification increased. In contrast to histopathologic healing, radiologic bone healing did not differ significantly among the study and control groups 2 weeks after surgery, whereas at 6 weeks, the results of radiologic bone formation were in accordance with those of histopathologic bone healing.

Calvarial and dural metastases of papillary thyroid carcinomas (PTC) are rarely reported in the medical literature. Most frequent calvarial metastases are seen to originate from lung, breast, and prostate cancers. Thyroid cancer metastases are generally well vascularized and cause destruction in the bone tissues. First choice of treatment in distant metastases of PTC is surgery and radioactive iodine treatment for the primary cause. Postsurgical radiotherapy is used in accepted and suitable patients.

Objectives: Bilateral vocal fold abductor paralysis (BVFAP) both deteriorates quality of life and may cause life-threatening respiratory problems. The aim of this study was to reduce respiratory symptoms in BVFAP patients using cricothyroid (CT) botulinum toxin (BTX) injection., Methods: Before and 2 weeks and 4 months after bilateral BTX injection into the CT muscles under electromyography; alterations in respiratory, acoustic, aerodynamic and quality of life parameters were evaluated in BVFAP patients with respiratory distress. For the respiratory evaluation modified Borg scale and spirometry, for the voice and aerodynamic evaluations Voice Handicap Index-30 (VHI-30), GRBAS, acoustic analysis (sound pressure level, F0, jitter%, shimmer%, noise-to-harmonic ratio) and maximum phonation time and for the quality of life assessment Short Form-36 (SF-36) form were used., Results: All patients were female with a mean age of 47±8.1 years. There was a mean time of 11.8±5.5 (minimum 2, maximum 23) months between BVFAP development and BTX injection. In all cases, other than one case with unknown aetiology, the cause of vocal fold paralysis was prior thyroid surgery. In total 18.6±3.1 units of BTX were applied to the CTs. In the preinjection period, and the 2nd week and 4th month after injection, the Borg dyspnea scale was 7.3/5.3/5.0, FIV1 (forced inspiratory volume in one second) was 1.7/1.7/1.8 L, peak expiratory flow (PEF) was 1.4/1.7/2.1 L/sec, maximum phonation time was 7.0/6.4/6.2 seconds and VHI-30 was 63.2/52.2/61.7 respectively. There was no significant alteration in acoustic analysis parameters. Many of the patients reported transient dysphagia within the first week. There were insignificant increases in SF-36 sub-scale values., Conclusion: After BTX injection, improvements in the mean Borg score, PEF and FIV1 values and SF-36 sub-scale scores showed the restricted success of this approach. This modality may be kept in mind as a transient treatment option for patients refused persistent tracheotomy or ablative airway surgeries.

The use of LigaSure™ vessel sealing system in head and neck surgery was reported to be reliable and safe, providing sufficient hemostasis and reducing operating time. The aim of this study was to evaluate efficacy of this technique in patients undergoing selective neck dissections. This study was carried out as a prospective controlled study at an otolaryngology department of a tertiary medical center between July 2013 and July 2015. Twenty-five patients older than 18 years who underwent unilateral selective neck dissection for head and neck cancer were included in the study. In the control group (group 2, 10 patients) only monopolar and bipolar diathermy was used; in the Ligasure group (group 1, 15 patients) Ligasure was used for hemostasis and dissection in addition to the conventional techniques. Cervical lymphadenectomy time, operation time, preoperative hemoglobin levels, preoperative hematocrit levels, postoperative hemoglobin levels, postoperative hematocrit levels, total neck drainage and drain removal time were analyzed and compared between the groups. Median operation time in group 1 and 2 were 95 min (IQR = 35) and 142.5 min (IQR = 63), respectively. Median cervical lymphadenectomy time in group 1 and 2 were 55 min (IQR = 23) and 102.5 min (IQR = 49), respectively. Median operation time and cervical operation time were significantly lower in group 1 (p < 0.05). In conclusion, LigaSure™ vessel sealing system is a safe, efficacious technique and significantly lowers cervical lymphadenectomy and operation time in selective neck dissections compared to controls. Given the superb hemostatic properties, this technique should be in the surgeon's armamentarium when possible.

The aim of this study is to assess the effect of partial superficial parotidectomy and facial nerve dissection to electrophysiologic parameters of intraoperative facial nerve monitoring such as nerve stimulation threshold, stimulus amplitude and latency. Twenty-five patients who underwent partial superficial parotidectomy for benign parotid gland mass were included in the study. After the identification of the facial nerve main trunk, minimum stimulation threshold, latencies and amplitudes of the orbicularis oculi (electrode 1) and orbicularis oris (electrode 2) electrodes at 0.50 milliamperes (mA) were recorded. All of the recordings were repeated after the completion of parotidectomy. Median nerve dissection duration was calculated and size of the tumors was measured during macroscopic pathology. The median minimum nerve stimulation threshold was 0.15 mA [interquartile range (IQR) = 0.05] before and 0.15 mA (IQR = 0.08) after the parotidectomy (p = 0.02). Median nerve dissection duration was 49 min (IQR = 38). Median amplitude and latency in electrode 1 before and after the facial nerve dissection were 322 millivolts (mV) (IQR = 330), 370 mV (IQR = 370) (p = 0.02), 3 milliseconds (ms) (IQR = 1) and 4 ms (IQR = 2) (p = 0.05), respectively. Median amplitude and latency in electrode 2 before and after the facial nerve dissection were 396 mV (IQR = 275), 365 mV (IQR = 836) (p = 0.86), 3 ms (IQR = 1.5) and 4 ms (IQR = 1.5) (p = 0.17), respectively. Minimal nerve stimulation threshold and amplitude of electrode 1 were affected by facial nerve dissection among the electrophysiologic parameters (p = 0.02 and p = 0.02). Of the electrophysiological parameters only the latency of electrode 2 was significantly correlated with tumor size (p = 0.03). Besides, none of the parameters were predictive for a possible postoperative facial nerve dysfunction regarding superficial partial parotidectomy.

Objective: The aim of this study was to report the post-surgical and oncologic outcomes of patients who underwent supracricoid partial laryngectomy (SCPL)., Methods: 90 patients who underwent SCPL between 1994 and 2014 were reviewed. 45 patients underwent cricohyoidopexy (CHP) and 45 patients cricohyoidoepiglottopexy (CHEP). Median nasogastric (NG) tube removal time, decannulation time, overall survival, disease-free survival and local control rates were calculated. The effect of the type of surgery on functional and oncologic outcomes were assessed., Results: Median NG tube removal time was 16.5 days (IQR = 10) and 14 days (IQR = 9) in CHP and CHEP patients, respectively (p > 0.05). Median decannulation time was 30 days (IQR = 26) and 19 days (IQR = 15) in CHP and CHEP patients, respectively (p < 0.05). Resection of one arytenoid significantly increased NG tube removal time. Median follow-up time was 55 months. There were 15 oncologic failures and the median time interval for tumor recurrence was 9 months. Five-year overall survival rate was 80.4%. The 3- and 5-year disease-free specific survival rates were 81.7 and 76.7%, respectively., Conclusions: Given the more extensive surgery applied for CHP, functional outcomes were better in patients with CHEP. Resection of an arytenoid had a negative outcome on swallowing., (© 2016 S. Karger AG, Basel.)

The first aim of this study was to evaluate the survival of the patients who underwent surgery due to lip squamous cell carcinoma (SCC). Furthermore, the predictive value of the prognostic factors regarding overall outcome was also assessed. The secondary objective was to justify the need of a prophylactic neck dissection according to the tumor size. One hundred and one cases with lip SCC were included in this study. The data regarding prognostic factors and survival were retrospectively collected. The 5-year survival rate was found to be 82.1%. Among the multiple prognostic factors, only age and disease stage had significant impact on survival (p < 0.05). Lymph nodes were positive in two (3.0%) T1, 3 (11.5%) T2, one (16.6%) T3 and 3 (100%) T4 patients. In Turkish population, the 5-year survival rate was found to be 82.1%. Age and disease stage were independent factors which have significant impact on survival. In geriatric population, the 5-year survival rate was 69.6%. There was an increased prevalence of the disease among women in the geriatric population. We suggest elective neck dissection and aggressive treatment for T2 tumors especially if the patient has multiple risk factors such as high tumor thickness and poor prognostic indicators such as increased age.

The purpose of this study was to evaluate the air kinetics of well- and poor-speaking patients and their upper (UES) and lower (LES) esophageal sphincter pressures . The esophageal speech capability of 23 total laryngectomy patients was assessed with the Wepman scale. LES and UES points and pressures were measured, and air kinetics were compared. All patients were male, with an average age of 58 years. Both the LES and UES pressures were not statistically different between good-speaking and poor-speaking patients (p > 0.05). The ability to speak was estimated only by looking at tracings. Good speakers are able to retain air successfully and on a long-term basis between the upper and lower esophageal sphincters. During short and/or rapid speech, these patients are able to rapidly suck and then expel the air from their upper esophagus. During long speeches, after sucking the air into their distal esophagus, they used the air in the upper part of the esophagus during the speech, only later seeming to fill the lower esophagus with the air as a possible reserve in the stomach. It has been shown that the basic requirement for speaking is the capacity to suck and store the air within the esophagus. For successful speech, the air should be stored inside the esophagus. MII technology contributes to our understanding of speech kinetics and occupies an important place in patient training as a biofeedback technique.

The tumor suppressor APC employs its conserved armadillo repeat (ARM) domain to recognize many of its binding partners, including Amer1/WTX, which is mutated in Wilms' tumor and bone overgrowth syndrome. The APC-Amer1 complex has important roles in regulating Wnt signaling and cell adhesion. Three sites A1, A2, and A3 of Amer1 have been reported to mediate its interaction with APC-ARM. In this study, crystal structures of APC-ARM in complexes with Amer1-A1, -A2, and -A4, which is newly identified in this work, were determined. Combined with our GST pull-down, yeast two-hybrid, and isothermal titration calorimetry (ITC) assay results using mutants of APC and Amer1 interface residues, our structures demonstrate that Amer1-A1, -A2, and -A4, as well as other APC-binding proteins such as Asef and Sam68, all employ a common recognition pattern to associate with APC-ARM. In contrast, Amer1-A3 binds to the C-terminal side of APC-ARM through a bipartite interaction mode. Composite mutations on either APC or Amer1 disrupting all four interfaces abrogated their association in cultured cells and impaired the membrane recruitment of APC by Amer1. Our study thus comprehensively elucidated the recognition mechanism between APC and Amer1, and revealed a consensus recognition sequence employed by various APC-ARM binding partners.

Background: Basal cell carcinoma (BCC) in central facial locations and tumors with positive margins are at a higher risk of recurrence. The most effective treatment is total excision, which includes an adequate pathological margin., Objective: To evaluate the outcome of the patients who underwent surgery for BCCs of the head and neck and of those who had positive surgical margins where Mohs surgery is not available., Methods: This study was conducted at Ege University Medical School between 2004 and 2014. One hundred thirty patients with 154 BCC who underwent surgical excision were included. In the histopathologic report, the existence of positive margin, BCC subtype, localization of the tumor, and distance of margins to the tumor were evaluated., Results: Twenty-three lesions (14.9%) of 22 patients revealed positive surgical margins. Six patients (26.1%) had recurrences on the surgical site. The BCC subtypes of recurrent patients were reported to be multifocal superficial in 2 (33.3%), infiltrative (16.7%) in 1, and micronodular (50%) in 3., Conclusion: Patients with superficial multifocal or micronodular tumors should undergo reoperation because of high recurrence rates.

Objective: To report post-surgical and oncological outcomes of 68 patients treated with frontal anterior laryngectomy with epiglottic reconstruction., Study Design: Demographic data and all information regarding histopathological grade, initial tumor stage and neck status, follow up time, postoperative complications, nasogastric tube removal time, decannulation time and recurrences were collected from the database and follow-up forms., Setting: All patients between 1994 and 2014 who were treated with frontal anterior laryngectomy with epiglottic reconstruction for early glottic carcinoma at Ege University Otolaryngology Clinic were included in the study., Subjects and Methods: Sixty-six of the patients were male and 2 were female with a median age of 57.5 years (IQR 53-63.75, range 44-75). Four patients had a tumor stage of T1a, 43 had T1b and 21 had T2. Median nasogastric tube removal time, decannulation time, overall and disease free survival rates were calculated., Results: Median nasogastric tube removal time was 10 days. Median decannulation time was 12 days. Median N/G tube removal and decannulation times were higher in T2 patients but this did not reach statistical significance (p>0.05). Median follow-up time was 68.5 months (6-222 months). Five year disease free survival was 93.5%. There were 6 oncologic failures which were salvaged with total laryngectomy, neck dissection and adjuvant radiotherapy., Conclusion: According to our results, which is one of the largest reported FAL with epiglottic reconstruction series in the English literature, this procedure's local control and survival rates are high with good functional results., (Copyright © 2015 Elsevier Inc.

Conclusions: p53 overexpression (>5%) in the surgical margins was more valuable than in the primary tumor tissue for the prediction of local recurrence among surgically treated early glottic cancers. This is the first study to compare p53 values in both primary tumor and surgical margin tissues of the same patients with early glottic cancers., Objective: To assess the prognostic value of p53 expression in the surgical margins of early glottic cancers treated with external laryngeal surgery in the prediction of local recurrences., Methods: Fifteen patients with early glottic cancer with local recurrences (group 1) and 15 without any recurrences (group 2) were included in the study. p53 expression was determined in both the tumor and the tumor-negative surgical margins., Results: Median p53 in the primary tumor was 55% (interquartile range (IQR) = 67) and 5% (IQR = 71) in groups 1 and 2, respectively (p = 0.178). Median p53 in the surgical margin was 11% (IQR = 13) and 2% (IQR = 2) in groups 1 and 2, respectively (p = 0.001). In the logistic regression analysis only surgical margin p53 value was significant in the prediction of recurrences (odds ratio (OR) = 1.68, 95% CI = 1.1-2.6, p = 0.017). Receiver operating characteristic (ROC) curve analysis demonstrated that the area under the curve was 0.86 (p = 0.002) and 0.65 (p = 0.180) in the surgical margin and the primary tumor, respectively.

The adenomatous polyposis coli (APC) membrane recruitment (Amer) family proteins Amer1/Wilms tumour gene on the X chromosome and Amer2 are binding partners of the APC tumour suppressor protein, and act as negative regulators in the Wnt signalling cascade. So far, nothing has been known about the third member of the family, Amer3. Here we show that Amer3 binds to the armadillo repeat domain of APC, similarly to Amer1 and Amer2. Amer3 also binds to the Wnt pathway regulator conductin/axin2. Furthermore, we identified Amer1 as binding partner of Amer3. Whereas Amer1 and Amer2 are linked to the plasma membrane by an N-terminal membrane localization domain, Amer3 lacks this domain. Amer3 localizes to the cytoplasm and nucleus of epithelial cells, and this is dependent on specific nuclear import and export sequences. Functionally, exogenous Amer3 enhances the expression of a β-catenin/T-cell factor-dependent reporter gene, and knockdown of endogenous Amer3 reduces Wnt target gene expression in colorectal cancer cells. Thus, Amer3 acts as an activator of Wnt signalling, in contrast to Amer1 and Amer2, which are inhibitors, suggesting a nonredundant role of Amer proteins in the regulation of this pathway. Our data, together with those of previous studies, provide a comprehensive picture of similarities and differences within the Amer protein family., (© 2013 FEBS.)

Laryngotracheal invasion worsens the prognosis of thyroid cancer and the surgical approach for laryngotracheal invasion is controversial. In this paper, partial full-thickness excision of the cricoid cartilage with supracricoid laryngectomy and reconstruction of existing defect with thyroid cartilage are explained in a patient with papillary thyroid carcinoma invading the thyroid cartilage and cricoid cartilage without intraluminal invasion. Surgical indication should not be established by the site of involvement in thyroid carcinomas invading the larynx, as in primary cancers of the larynx. We think that partial laryngectomy according to the involvement site and the appropriate reconstruction techniques should be used for thyroid cancer invading the larynx.

Objectives: To identify the effects of laryngopharyngeal reflux (LPR)-related laryngeal findings on objective voice parameters., Methods: Two hundred and thirty patients clinically diagnosed as having LPR and 48 healthy controls were included. The reflux finding score was determined for each subject via videolaryngoscopy. The acoustic parameters evaluated were jitter, shimmer, noise-to-harmonic ratio and Voice Turbulence Index (VTI)., Results: Shimmer and VTI showed statistically significant differences between the LPR and control groups among males (p < 0.05). For females, all of the 4 acoustic voice parameters were significantly different between the two groups (p < 0.05). Erythema/hyperemia was found to affect the highest number of voice parameters. VTI was found to be affected by the highest number of laryngeal findings., Conclusion: Objective voice changes were documented in LPR patients, with VTI being the most affected parameter, and therefore it should be considered in the acoustic analysis of patients with LPR in addition to the conventional parameters. With hyperemia in the first rank, ventricular obliteration, pseudosulcus and vocal fold edema are found to have an impact on voice, suggesting that these should be concentrated on in the diagnosis and follow-up of LPR patients with voice disorders., (Copyright © 2012 S.

The techniques used in the diagnosis of gastroesophageal reflux disease (GERD) have insufficient specificity and sensitivity in diagnosing laryngopharyngeal reflux (LPR). The purpose of this study was to evaluate the role of esophagogastroduodenoscopy (EGD) and laryngological examination in the diagnosis of LPR. A total of 684 diagnosed GERD and suspected LPR patients were prospectively scored by the reflux finding score (RFS) which was suggested by Koufman. A total of 484 patients with GERD who had RFS ≥ 7 were accepted as having LPR. 248 patients with GERD plus LPR on whom an endoscopic examination was performed were evaluated. As a control group, results from 82 patients with GERD who had RFS <7 were available for comparison. The GERD symptom score (RSS) was counted according to the existence of symptoms (heartburn/regurgitation) and frequency, duration, and severity. The reflux symptom index (RSI) suggested by Belafsky et al. was also evaluated. The relationship between esophageal endoscopic findings, RSS, RFS and RSI was investigated. Mean age was 46 ± 12 (19-80). The mean values of RSS, RFS, and RSI were 18.9 ± 7.7, 10 ± 2.2, 16.6 ± 11.9, respectively. Erosive esophagitis was detected in 75 cases (30%). Hiatus hernia was observed in 32 patients (13%). There was no correlation between RSS and RFS, RSI. The severity of esophagitis did not correlate with the severity of the laryngeal findings. LPR should be suspected when the history and laryngoscopy findings are suggestive of the diagnosis. EGD has no role in the diagnosis of LPR.

Background: The aim of this study was to compare the facial photogrammetric analysis results of the Turkish population who are pleased with their facial appearance with the facial analysis data of patients who underwent rhinoplasty in order to find the most prominent objective facial measurements that lead patients to surgical correction of the nose., Methods: Forty rhinoplasty patients (20M, 20F) and 40 people without nasal deformity (20M, 20F) were included in this study. Rhinobase software was used for photogrammetric facial analysis., Results: The differences in the nasofrontal angle (NFA), nasolabial angle (NLA), chin projection (CP), middle facial height (MFH), and tip deviation angle (TDA) between the patient and the control groups and between the males and females were statistically significant (P < 0.05)., Conclusion: The most significant differences between the control group and the patient group were crooked nose, obtuse NFA, acute NLA, chin underprojection, and increased MFH.

Background: Sphenopalatine artery (SPA) ligation or cauterization stands to be one of the most common management options of refractory epistaxis. Ramification pattern of SPA as it passes through sphenopalatine foramen (SPF) has not been clearly established. The aim of this study is to investigate situations in which middle meatal approach may fail due to anatomic variations of SPA and to define a minimally invasive surgical cauterization procedure. Anatomic variations of SPA were determined by microdissection of 20 adult sagittally cross-sectioned head specimens., Methods: Branching characteristics of SPA and its anatomic relations were evaluated and anatomic variations were noted., Results: SPA was generally (80%) forming branches within SPF before entering into the nasal cavity. In 20% of the specimens, SPF was located superior to the horizontal lamella of the middle turbinate, and accessory foramen was present in 10%. In 10% of the cases, the posterior lateral nasal branch was situated as two branches in a deep sulcus in the middle meatus., Conclusion: The ramification pattern of SPA can not be fully exposed without resection of the posterior part of the middle turbinate via the middle meatal approach. Two-step procedures are advocated in reducing failure rates. Previously defined two-step procedures are relatively invasive. A less invasive procedure is defined based on the variations of SPA and SPF.

Purpose: To retrospectively assess prognostic factors and patterns of relapse in patients with oral tongue cancer treated by adjuvant radiotherapy (RT)., Patients and Methods: Between 1995 and 2005, 65 patients with stage II-IV oral tongue cancer were treated with postoperative adjuvant RT at our institution. The influence of multiple patient- and treatment-related factors on local and regional control, and overall survival (OS), locoregional failure- free survival (LRFFS) and cause-specific survival (CSS) were evaluated. Median patient follow-up was 74 months., Results: Five-year disease-free survival (DFS), LRFFS and CSS rates were 56, 60 and 58%, respectively. During the study period 27 (41.5%) patients had locoregional failures. Seventeen of the recurrences were in the primary tumor region, 4 in the neck, 6 in both regions. Most of the local failures occurred in the first year (median 13 months, range 5-15). Gender, T stage, stage (AJCC TN stage), surgical margin, localization of tumor, and hemoglobin level had predictive value for improved local-regional control in univariate analysis. In total, 35 deaths occurred: 28 patients died of progressive disease, one patient died due to another primary tumor (esophageal cancer) and 6 patients died of other causes., Conclusion: Local failure was the most important problem concerning the final outcome. High local recurrence rates and poor survival rates are important issues in the management of oral tongue cancer. Further strategies should be directed to enhancing cure rates.

Objective: To evaluate the impact of thyroidectomy and the possible effects of factors such as patient sex, operation type, and surgeon experience on objective voice parameters of patients undergoing thyroidectomy without laryngeal nerve injury., Design: Prospective study., Setting: University hospital., Patients: Thirty-six patients undergoing primary thyroidectomy because of thyroid disease., Main Outcome Measures: The effect of thyroidectomy on voice was examined by recording the voices of the patients before and 1 week after thyroidectomy. The Multi-Dimensional Voice Program was used for capturing and analyzing the voice samples., Results: On postoperative examination of objective voice changes, thyroidectomy had no multivariate effect on the combination of voice parameters. Patient sex, type of surgery, and surgeon experience had no effect on the combination of voice parameters before and after thyroidectomy. Regardless of within-patient factors (type of surgery, patient sex, and surgeon experience), 4 acoustic parameters (highest fundamental frequency, standard deviation of average fundamental frequency, phonatory average fundamental frequency range in semitones, and degree of subharmonics) significantly decreased after thyroidectomy (P < .05). Although they tended to be worse, none of the acoustic parameters showed significant changes in male patients. However, significant changes in some of the acoustic parameters of female patients were observed. Highest fundamental frequency, standard deviation of average fundamental frequency, phonatory average fundamental frequency range in semitones, absolute jitter, relative average perturbation, pitch perturbation quotient, shimmer in decibels, percentage of shimmer, amplitude perturbation quotient, noise to harmonic ratio, and degree of subharmonics values were all lower in female patients after thyroidectomy (P < .05)., Conclusions: Voice changes may occur after thyroidectomy without any evident laryngeal injury, and deterioration and amelioration of acoustic parameters can be observed to occur differently among male and female patients. Preoperative and postoperative objective voice analyses may be helpful in documenting voice changes.

Aberrant course of the internal carotid artery within the middle ear is a rare condition. Surgical interventions following clinical or radiological misinterpretations may lead to fatal complications. A 23-year-old female patient presented with a hearing impairment of 10-month duration. On otoscopic examination, the left tympanic membrane was intact, but there was a pulsatile lesion in the tympanic cavity, synchronous with the heartbeats. Pure-tone audiometric examination of the left ear showed a unilateral mixed hearing loss, especially in low frequencies. Computed tomography showed protrusion of the internal carotid artery into the middle ear from the lateral and superior aspects of the cochlea. Magnetic resonance imaging and MR-angiography showed a left-sided deviation of the left internal carotid artery near the cochlea, associated with a filling defect. The caliber of the left internal carotid artery was narrower than the right one in the middle ear, and its proximal part was thinner. A diagnosis of aberrant internal carotid artery was made.

Pulsatile tinnitus associated with normal otoscopic findings may present as the only sign of a potentially life-threatening serious disease such as a dural arteriovenous fistula (dAVF) of the transverse or sigmoid sinus. If left untreated, dAVFs may lead to focal neurologic symptoms, intracranial hypertension, or hemorrhage, and finally to death. We report two cases of dAVF presenting with pulsatile tinnitus. Following diagnosis, both patients underwent transarterial embolization, after which their symptoms resolved.

One of the most challenging and neglected issues in medicine is the effective recording of the data obtained from the patients. The "European Work Group on the Genetics of Hearing Impairment," which has been working since 1996, proposed a few questionnaires to collect data regarding the phenotype, ENT findings, audiological examination findings and other special investigations. In this study, a computerized patient database application named "Izmir H.E.A.R version 1.0," written in Delphi 4.0 for Windows for recording the patients with hearing problems, is presented. The application consists of a modular form, including information about identity, genetic condition, proband query, audiology and vestibular tests, phenotype, pedigree and special examinations, which allows data entry on all these issues. It has been developed by using the guidelines of Hereditary Deafness Epidemiology and Clinical Research (H.E.A.R.) and by the experience gained within the last 10 years by the authors. The target population of the program is the ENT clinicians, audiologists, epidemiologists, geneticists and researchers in the field. The main idea is to create a program serving the needs of both the daily routine work and research purposes and to distribute this program to the above-mentioned specialists, to encourage them to try the first version and to find a standard and/or better way to collect data. For this reason, the program aims to be multilingual, and the currently available languages are English, German, Spanish and Turkish.

Objective: To examine whether insulinlike growth factor I (IGF I), IGF II and IGF binding protein 3 (IGFBP 3) in serum and peritoneal fluid (PF) correlate with the presence and severity of endometriosis., Study Design: Case-control study including 29 patients with endometriosis and 15 controls. The revised American Fertility Society classification stages of I and II were pooled as early-stage (n = 15), and stages III and IV were taken as late stage (n = 14). Simultaneous sampling of blood and PF was performed during laparoscopy, and IGF I, IGF II and IGFBP 3 levels were determined by immunoradiometric assay., Results: The serum levels of all three proteins were higher than PF levels except for a reversed IGF I PF: serum ratio in the early stage. There were no significant differences in IGF II and IGFBP 3 levels among the groups. The mean serum IGF I levels of controls and early-stage patients were significantly lower than those in the late stage. Also, mean PF IGF I levels in controls were significantly lower than in the late stage., Conclusion: IGF I may be an important mediator in the development and/or maintenance of endometriosis or progression to late-stage disease.
