A comparison of unilevel and multilevel surgery in obstructive sleep apnea syndrome.

We conducted a retrospective study of 35 adults who had undergone tongue base suspension in addition to other surgery for the treatment of obstructive sleep apnea syndrome (OSAS). Our goal was to determine the most effective surgical approach by comparing these patients' preoperative apnea-hypopnea index (AHI) with their postoperative scores at 6 months. The 35 patients were divided into three groups based on a preoperative assessment of their level of airway obstruction; the assessment included a determination of AHI and endoscopic findings during the MÜller maneuver.

The effects of tumor size, degree of differentiation, and depth of invasion on the risk of neck node metastasis in squamous cell carcinoma of the oral cavity.

Cervical lymph node metastasis is the most important prognostic factor in patients with head and neck carcinoma. We retrospectively analyzed the effects of three different variables-tumor size, degree of differentiation, and depth of invasion-on the risk of neck node metastasis in 50 adults who had been treated with surgery for primary squamous cell carcinoma of the oral cavity. Primary tumor depth and other pathologic features were determined by reviewing the pathology specimens.

[Management of recurrent lower lip carcinomas].

Objectives: In this study patients who had locoregional recurrence of lower lip carcinomas after therapies such as surgery, electrocoagulation, cryotherapy or traditional local therapies are discussed.

Patients And Methods: The records of 16 cases (1 female, 15 males; mean age 58 years; range 30 to 83 years) with recurrent lower lip carcinoma admitted between March 2002 and September 2007 to Dr. Abdurrahman Yurtarslan Oncology Training and Research Hospital, Ear, Nose and Throat Department were retrospectively reviewed.

Measurement of tympanic cavity volume by the Cavalieri principle in Turkish population.

Objectives: The aim of this study is to measure the tympanic cavity (TC) volumes with Cavalieri principle using computed tomography (CT) scanning of temporal bones, to investigate the difference between the right and the left ears with respect to sexes and to exemplify the TC volume measurements.

Patients And Methods: Clinical records of 91 patients (46 females 45 males; mean age 48.1 years; range 15 to 60 years) whose TCs were measured at ear nose throat clinic of Ankara Oncology Education and Research Hospital between January 2007 and March 2008, were retrospectively investigated.

Can the Müller maneuver detect multilevel obstruction of the upper airway in patients with obstructive sleep apnea syndrome?

Objectives: Our aim is to figure out the role of Müller maneuver (MM) to detect the level of upper airway obstruction and the severity of obstructive sleep apnea syndrome (OSAS).

Patients And Methods: In this study, polysomnographies were made after the routine otorhinolaryngological examination including MM in patients admitted with OSAS suspicion in Ankara Oncology Training and Research Hospital's Department of Otorhinolaryngology, Sleep Medicine Policlinic. Two-hundred and twenty-one OSAS patients (142 males, 179 females; mean age 47.
