RESUMO
BACKGROUND: In this study, we observed the frequency of side effects encountered when the neural integrity monitor electromyogram endotracheal tube (NIM-EMG-ETT) was used in thyroidectomy and parathyroidectomy surgeries. METHODS: After obtaining hospital ethics committee approval, 239 cases affiliated with the American Society of Anesthesiologists (ASA II-IV) who used NIM EMG tubes in thyroid and parathyroid surgery were included in the prospective observational study. Tube and patient-related complications encountered with two different NIM EMG-ETT (silicone and polyvinyl chloride-PVC) were recorded. RESULTS: The average age of the patients is 49.50 ± 13.44 years, the average BMI is 28.25 ± 4.91 kg/m2, the median surgery time is 115 (32-475) minutes, 75.7% are women, 97.5% are ASA II. Additional diseases other than thyroid and parathyroid problems were present in 77.3%. Thyroidectomy was performed in 73.2% of the patients. In our study, only 0.8% of patients with transient recurrent laryngeal nerve RLN paralysis were observed in thyroid and parathyroid surgeries performed using NIM-EMG tubes, 3 patient already had nerve involvement in the preoperative period. The most common complication was loss of stimulation response related to tubes and patient-related ventilation failure. There was no difference between the complications of silicone and PVC tubes except for irregular EMG response. CONCLUSIONS: There was no significant difference in side effects other than irregular EMG response in the two different tubes we used in our study. It was observed that prolonging the surgical time increased the risk of irregular EMG response. It should not be forgotten that no matter which NIM-EMG tube is used, additional risks are encountered during the intubation and extubation process. In order to avoid negative consequences, it is necessary to follow the usage rules recommended by the manufacturer when using NIM-EMG tubes.

OBJECTIVE: To compare the efficacy of tonsillectomy and expansion sphincter pharyngoplasty (ESP) in the surgical treatment of obstructive sleep apnea (OSA). METHODS: OSA patients with Friedman grade III-IV tonsil hypertrophy diagnosed with polysomnography were separated into two groups according to the surgery performed, as the classic tonsillectomy group (Group 1) and the ESP group (Group 2). The primary endpoint of the study was to determine the Apnea-Hypopnea Index (AHI) value. RESULTS: Group 1 comprised 24 patients with median preoperative AHI of 19.7 and postoperative AHI of median 11.8 (p = .0001). Group 2 comprised 29 patients with median preoperative AHI of 25.1 and postoperative AHI of median 16.3 (p = .0001). Nine (37.5%) of the 24 patients in Group 1 accepted as cure (79.1%). Eight (27.5%) of the 29 patients in Group 2 accepted as cure (72.4%). CONCLUSION: There was no superiority of ESP over tonsillectomy in patients with lateral pharyngeal obstruction.
RESUMO
OBJECTIVE: To reveal the incidence and predictive parameters of occult cervical lymph node metastasis (LNM) in patients with cN0 laryngeal squamous cell cancer (LSCC) who underwent surgery as definitive treatment. METHODS: Patients with cN0 laryngeal cancer who had undergone elective neck dissection together with partial or total laryngectomy between January 2006 and November 2020 were retrospectively analyzed. Clinical and histopathologic predictors of occult metastasis were also analyzed. Follow-up data were used to obtain recurrence and survival analysis. RESULTS: A total of 86 patients with a mean age of 62.5 years were included in the study. Occult LNM was detected in 15 (17.4%) patients. Tumor grade, pT stage, thyroid cartilage invasion, and extralaryngeal extension were found to predict occult neck metastasis in univariate analysis. The mean follow-up time was 60.7 months and in the survival/recurrence analysis, pT stage, tumor location, tumor grade, presence of occult metastasis, pre-epiglottic space involvement. and extralaryngeal extension were found to predict poorer outcome. CONCLUSION: Overall occult LNM is low (17.4%) in N0 laryngeal cancer, but the presence of LNM is a poor prognostic factor. Correct determination of the neck status and proper treatment is crucial. The incidence of LNM is very low in T1-T2 stages and well-differentiated tumors. The "wait and see" strategy may be applied in T1-T2 cases as well as selected T3 cases with well-differentiated tumors.

Background/aim: Because of close relations to important anatomical structures such as cavernous sinus and optic nerve, sphenoid sinus variations must be well trained by the otolaryngologist who has an interest in endoscopic sinus surgery. Newly defined sphenoseptal cell (SSC) is one of those variations that may lead to insufficient endoscopic sinus surgery outcomes if not defined preoperatively with imaging studies. The present study aimed to present the main characteristics of this special type of nasal cell. Materials and methods: In this study, 610 paranasal sinus CT scans were analyzed and reviewed retrospectively between May 2018 and December 2019. Also, endoscopic findings of SSC that cause a surgical catastrophe in identifying skull base and sella are presented during transnasal transsphenoidal pituitary surgery. Results: According to its definition and relation to the sphenoid sinus and the skull base, an SSC was seen in 21 scans of 610 patients (3.4%), 11 were women (55%) and 10 were men (45%). Conclusion: Although an SSC is a rare variation of nasal air cells, preoperative diagnosis of this cell is of paramount importance in some patients during endoscopic transnasal surgery for the identification of skull base.

OBJECTIVE: This study aimed to investigate the correlation between morphological features of vocal fold polyps (VFPs) and subjective/objective voice parameters. METHODS: Perceptual evaluations, aerodynamic and acoustic tests were performed on 47 patients with VFPs. Still images were captured from video and the morphological features associated with the size of VFP were quantified. To reveal the correlation between size-related morphological features (length of polyp base, the ratio of polyp base to vocal fold length, glottal gap area) and objective/subjective parameters of voice, Pearson's and Spearman's tests were carried out. RESULTS: This cohort was composed of 30 (63.8 %) male and 17 (36.2%) female patients with the mean age of 45.2 years and 41.3 years, respectively. No correlation was found between the morphological features of VFPs and any of perceptual, aerodynamic and acoustic voice parameters. CONCLUSIONS: Our findings indicated that controversies still exist regarding the role of vocal fold polyp morphology in clinical decision making.

Background: Head and neck paragangliomas are slowly growing benign tumors and they originate from specialized neural crest cells. Aims/objectives: This study aimed to express the safety of paraganglioma surgery regarding complications, treatment, and outcomes of patients with head and neck glomus tumors. Materials and methods: Medical records of patients who were operated because of head and neck paraganglioma between 2006 and 2016 were reviewed. Results: The study group consisted of 49 patients (M/F: 6/43). The patients were distributed as follows: 22 glomus caroticum (GC) (44.8%), 8 glomus jugulare (GJ) (16.3%), 10 glomus tympanicum (GT) (20.4%), 4 glomus vagale (GV) (8.1%), 2 GC + GV (4%), 2 bilateral GC (4%) and 1 thyroidal glomus tumor (2%). All GC and GV tumors were resected via cervical approach. Three of GJ tumors were resected through transmastoid approach while five of them were resected through both transmastoid and cervical approach. Nine GT tumors were resected via transmastoid approach. One patient received cyberknife. Thyroid paraganglioma was diagnosed incidentally after total thyroidectomy. Mean follow-up period was 61.92 ± 35.11 months (1-124 m). Conclusions and significance: The choice of treatment depends on the size, location and biologic activity of tumor as well as the physical condition of the patient. Our results show that glomus tumors can be resected with low mortality and morbidity rates due to developing imaging and microsurgical methods.
