Comparative study of anatomical features of primary and accessory maxillary ostia between patients with obstructive sleep apnea and healthy controls.

Purpose: The purpose of this study was to examine how the size and shape of the maxillary sinus and its ostia (the primary maxillary ostium and accessory maxillary ostium) relate to each other in patients with OSA using computed tomography (CT) scans. Additionally, the study aimed to explore whether or not obstructive sleep apnea (OSA) had an effect on these structures.

Methods: CT images of patients diagnosed with OSAS and healthy participants were evaluated to compare the patency, location, dimension, and presence of PMOs and AMOs using the Mann-Whitney U, Student t, and chi-square tests.

Failure of Concurrent Chemoradiotherapy for Organ Preservation in Laryngeal Cancer: Survival Outcomes and Recurrence Patterns.

Although definitive chemoradiation (CRT) has been used for locally advanced laryngeal cancer for more than 2 decades, studies focusing on CRT failures in advanced laryngeal cancer are scarce. In this study, we aimed to determine the failure patterns and the survival outcomes in the patients who had recurrence after concurrent CRT for laryngeal cancer. Clinical records of the patients who had definitive concurrent CRT for laryngeal cancer between 2001 and 2014 at a tertiary referral center were reviewed.

The demographics and histopathological features of oral cavity cancers in Turkey.

Background/aim: This study aimed to examine the demographics and histopathological features of oral cavity cancers (OCCs) managed in our clinic.

Materials And Methods: Patients who were diagnosed with OCCs in the Gazi University Otorhinolaryngology Department between the years 1993 and 2013 were retrospectively enrolled in the study. Surgical archive charts and pathology records were reviewed in detail regarding the anatomical and histopathological profiles of the tumors, as well as the demographic data of the patients.

Comparison of three different concurrent chemoradiation regimens for treatment of laryngeal cancer.

During last decades, laryngeal organ preservation strategies have emerged. The data about the oncological outcomes mainly come from multi-institutional prospective studies. In this study, we aimed to determine the oncological outcomes of different organ preservation regimens applied in routine practice.

Mucosal melanoma of the head and neck: recurrence characteristics and survival outcomes.

Objective: The aim of this study was to review oncologic outcomes and recurrence characteristics of head and neck mucosal melanomas (HNMMs) managed at a tertiary referral center.

Study Design: Clinical records of 10 patients who were managed for HNMMs between 2001 and 2013 were retrospectively analyzed.

Results: The median age was 66 years (range 28-76 years) and male/female (M/F) ratio was 1:5.

The basaloid variant of squamous cell carcinoma of the larynx.

Introduction: Basaloid squamous cell carcinoma (BSCC) is a rare subtype of squamous cell carcinoma (SCC). Because of its rarity, both clinical and prognostic features of this variant are not well known.

Objective: In this study, we aimed to determine the frequency of BSCC and other SCC variants among all laryngeal SCC cases, and to determine clinical and prognostic features of BSCC variant.

Neoplasms of the hard palate.

Purpose: Although the most common neoplastic lesion of the oral cavity is squamous cell carcinoma (SCC), primary neoplastic lesions of the hard palate have not been systematically reviewed to date. The aim of this study was to determine the histopathologic composition and characteristics of neoplasms of the hard palate.

Materials And Methods: A retrospective analysis of 66 patients with a primary neoplasm of the hard palate managed at the authors' institution from 1985 through 2012 was performed.

An analysis of petrous bone cholesteatomas treated with translabyrinthine transotic petrosectomy.

Conclusion: In cases of petrous apex cholesteatoma, radical removal should be prioritized over an unreasonable sparing of hearing or facial symmetry. Restoration of facial nerve function is achievable by reanimation procedures.

Objectives: To analyze clinical manifestations, surgical findings, and postoperative functional results of petrous apex cholesteatoma.
