Publication The prognostic value of thyroid gland invasion in locally advanced laryngeal cancers(Taylor, 2021-08-16) Aslıer, Mustafa; Uçurum, Bahar Ezgi; Kaya, Hilmi Cem; Coşkun, Hakan; ASLIER, MUSTAFA; UÇURUM KANTARCI, BAHAR EZGİ; KAYA, HİLMİ CEM; COŞKUN, HAMDİ HAKAN; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Kulak Burun Boğaz-Baş Boyun Cerrahisi Anabilim Dalı; 0000-0001-8257-0979; 0000-0003-0786-4453; 0000-0003-3670-4651; 0000-0002-0881-1444; ABH-1328-2021; KHB-5653-2024; GDF-8132-2022; GEH-1871-2022; DVC-7511-2022Background Locally advanced laryngeal cancers can spread to the thyroid gland by direct invasion of cricothyroid membrane. The prevalence of thyroid gland invasion (TGI) and the predictive factors of TGI were well described in literature. However, the association of TGI with survival was undetermined yet. Objectives The aim of this study is to analyze the effects of TGI on survival rates in patients with locally advanced laryngeal cancer. Materials and methods Medical records of 91 patients who underwent total laryngectomy with thyroidectomy were retrospectively reviewed. Demographical, clinical, and histopathological characteristics of the patients were noted. Kaplan-Meier test was used for survival analysis. Results Histopathology reports revealed the prevalence of TGI as 14.3% (13/91). Survival analyses showed that TGI did not affect recurrence free (p = .078) and overall (p = .080) survival rates. Conclusions Thyroid gland invasion is one of the characteristic features of locally aggressive laryngeal tumors. In this study, TGI is not a statistically significant prognostic factor that has impact on survival of the patients with locally advanced laryngeal cancer.Publication Inflammatory complications of vocal fold injection with hyaluronic acid: A multiinstitutional study(TUBİTAK, 2021-01-01) Enver, Necati; Azizli, Elad; Akbulut, Sevtap; Tatar, Emel Cadalli; Yelken, Muhammed Kursad; Ozturk, Kayhan; Birkent, Ahmet Hakan; Buyukatalay, Zahide Ciler; Ozgursoy, Ozan Bagis; Oguz, Haldun; Coskun, Hakan; COŞKUN, HAMDİ HAKAN; Bursa Uludağ Üniversitesi/Tıp Fakültesi.; 0000-0002-0881-1444Background/aim: This study aimed to assess the inflammatory adverse reactions of vocal fold injection laryngoplasty with hyaluronic acid.Materials and methods: This study was a retrospective chart review of patients who underwent vocal fold injection augmentation with HA injection from January 2005 to September 2016 in nine different institutions. Demographic data, indication for injection, injection techniques, types of injection material, settings of procedure, and complications were reviewed. The types of complication, onset time, and management of complications were also noted.Results: In all, 467 patients were identified. The majority of patients had been injected under general anesthesia (n = 382, 84.7%). For injection material, two different types of hyaluronic acid were used: hyaluronic acid alone or hyaluronic acid with dextranomer. Complications occurred in nine patients (1.9%). The majority of complications were inflammatory reactions (n = 7, 1.47%). Main symptoms were dysphonia and/or dyspnea with an onset of 0 h to 3 weeks after the hyaluronic acid injection. Three patients were hospitalized, one of which was also intubated and observed in the intensive care unit for 24 h. Systemic steroids and antibiotics were the main medical treatment in the majority of cases. There was no statistical difference in complication rates between patients who received hyaluronic acid and those who received hyaluronic acid with dextranomer (P = 0.220).Conclusion: Hyaluronic acid can be considered as a safe substance for the injection of vocal folds with a low risk of inflammatory reaction.Publication Laryngoscopic examination during the COVID-19 pandemic: Turkish voice speech and swallowing disorders society and Turkish professional voice society recommendations(Galenos Yayıncılık, 2020-09-15) Çobanoğlu, H.

This increases the occupational risk for health care workers. In otolaryngology clinic practice, patients with upper respiratory tract infection symptoms are common. Also, routine head and neck examinations such as oral cavity examination, nasal/nasopharyngeal examination, or video laryngostroboscopic evaluation are highly risky because of the aerosol formation. To emphasize this issue, two leading otolaryngology organizations in Turkey; 'Voice Speech and Swallowing Disorders Society', and 'Professional Voice Society' gathered a task force. This task force aimed to prepare a consensus report that would provide practical recommendations of the safety measurements during routine clinical care of laryngology patients. To fulfill this, universal aim, on the 2nd and 9th of May 2020, two web-based meetings were conducted by 20 expert physicians. This eighteen items list was prepared as an output.Publication The incidence of thyroid gland invasion in advanced stage laryngeal cancers with emphasis on risk factors and its impact on survival(Elsevier, 2021-07-01) Aslıer, Mustafa; Uçurum, Bahar Ezgi; Kaya, Hilmi Cem; Coşkun, Hakan; ASLIER, MUSTAFA; KAYA, HİLMİ CEM; UÇURUM KANTARCI, BAHAR EZGİ; COŞKUN, HAMDİ HAKAN; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Kulak Burun Boğaz Hastalıkları Anabilim Dalı.; 0000-0003-3670-4651; 0000-0002-0881-1444; CCA-0193-2022; JJJ-8575-2023; GEH-1871-2022; DVC-7511-2022Publication Lesions that mimic malignant tumors in nasopharyngeal biopsies: Case series of 10 years(Sage Publications Ltd, 2021-03-17) Özşen, Mine; Saraydaroğlu, Özlem; Yirmibeş, Selin; Coşkun, H.

These include inflammatory, metaplastic, and cystic lesions. We aimed to draw attention to rare tumor-like lesions that can be confused with malignancies and cause diagnostic difficulties clinically and radiologically. Methods: A total of 538 patients who underwent nasopharyngeal biopsy in our center between January 2010 and June 2020 were evaluated. Patient information was obtained from patient files and evaluated retrospectively. Results: A total of 19 of the 538 patients had tumor-like lesions that were included in the study. Granulomatous inflammation was present in seven cases, oncocytic metaplasia in four cases, benign cyst in five cases, fungal infection in two cases, and immunoglobulin G4-related disease in one case. Conclusions: The nasopharynx is a region where various lesions can be seen. Some lesions form tumor-mimicking mass effect, cause increased thickness, and lead to increased metabolic activity in positron emission tomography-computed tomography that create the illusion of a malignant tumor and histopathologic verification is crucial. We aimed to present these rare tumor-like lesions that should be kept in mind in the differential diagnosis.Publication Comparison of clinical results in nasal tip augmentation either via face to face or back to back technique with autogenous auricular conchal cartilage(Lippincott Williams & Wilkins, 2015-06-28) Şahin, Murat Sertan; Kasapoğlu, Fikret; Demir, Uygar Levent; Özmen, Ömer Afşin; Coşkun, Hakan; Basut, Oğuz; Sahin, Murat Sertan; KASAPOĞLU, FİKRET; DEMİR, UYGAR LEVENT; ÖZMEN, ÖMER AFŞIN; COŞKUN, HAMDİ HAKAN; BASUT, OĞUZ İBRAHİM; Uludağ Üniversitesi/Tıp Fakültesi/Kulak Burun Boğaz Cerrahisi Anabilim Dalı.; 0000-0002-4718-0083; 0000-0002-9698-0546; 0000-0002-0881-1444; A-1452-2019; AAI-3877-2021; BBC-2978-2021; CNQ-7672-2022; DVC-7511-2022; CFJ-8210-2022Objective:To compare the objective and subjective findings between patients who underwent nasal tip augmentation surgery via two different methods using autogenous auricular conchal cartilage.Materials and Methods:This study included the data of 21 patients who underwent nasal tip augmentation surgery. The patients were randomly divided in two groups according to the technique used to form a double layer columellar strut graft; either face to face (group 1) and back to back (group 2). All patients were assessed via nasal obstruction symptom evaluation scale (NOSE) and via acoustic rhinometry and rhinomanometry at preoperative and postoperative 1st and 6th months.Results:There was statistically significant improvement in symptom score in both patient groups with no difference inbetween. Total nasal resistance decreased nonsignificantly at the end of 6th month in both groups; 13.1Pa/cm(3) to 8.6Pa/cm(3) and 10.3Pa/cm(3) to 9.5Pa/cm(3) respectively. There was no significant increment in MCA values for both groups except left MCA1.Conclusions:We achieved good results in tip augmentation via both techniques. An autogenous conchal cartilage is a good alternative to replace lacking caudal septal cartilage. It provides safe and stable support to the nasal tip. However, further comprehensive studies with larger sample size and long follow-up are required to elucidate any difference between these two techniques.
