Repeated Atmospheric Pressure Alteration Effect on the Cochlea in Rats: Experimental Animal Study.

This study aimed to evaluate the effects of repeated pressure alterations on cochlear structures in rats in an attempt to understand indirectly the inner ear status of flight crew who are repeatedly exposed to pressure alterations. There were 12 adult Wistar albino rats equally divided into 2 groups: Group 1 (controls) and Group 2 (study group). The animals in Group 2 were exposed to repeated pressure changes in a pressure cabin which is regulated by manometers.

Dorsal Augmentation of Saddle Nose Deformity With Toothpick-Shaped Costal Cartilage Grafts in the Secondary Septorhinoplasty.

Saddle nose deformity is a challenging complication of septoplasty or septorhinoplasty, characterized by underprojected cartilaginous dorsum. Nasal dorsal augmentation is a significant part of reconstructive surgery of saddle nose deformities. In this study, the authors aimed to discuss the results of using toothpick-shaped costal cartilage grafts in nasal dorsal augmentation of saddle nose deformity.

Recovery of Tinnitus and Sensorineural Hearing Loss Due to Lysis of Arachnoid Adhesions in the Posterior Cranial Fossa: Is There a Novel Etiology in Neurotological Disorders?

We reported the recovery of sensorineural hearing loss and tinnitus in a 22-year-old man after complete removal of intracranial portion of jugular foramen schwannoma via the retrosigmoid approach. The aim of this case report was to present the excision of a large jugular foramen schwannoma via the retrosigmoid approach and to describe the improvement of sensorineural hearing loss related to arachnoid inflammations due to chronic arachnoiditis after suboccipital craniectomy. The recovery of sensorineural hearing loss and tinnitus after release of arachnoid adhesions may indicate the clinical significance of these adhesions or arachnoiditis, which should also be considered and investigated in the etiology of other neurotological diseases.

Influence of Time and Direction Information on Video Head Impulse Gains.

Objective: The objective of this study was to establish which factor leads to a higher vestibulo-ocular reflex (VOR) gain: the timing of the movement or the direction of the movement. For this purpose, healthy volunteers were examined under three conditions: (1) when they were informed about the timing of the head movement; (2) when they were informed about the direction of the head movement; and (3) when they knew both the timing and the direction of the head movement.

Materials And Methods: This study included data from 19 participants between the ages of 20 and 23 years with no neurological or vestibular ailments.

Association of Helicobacter pylori infection with olfactory function using smell identification screening test.

The aim of the present study is to investigate the role of Helicobacter pylori in olfactory function. Thirty-six patients (mean age 38.5) aged between 18 and 55 years who were diagnosed with H.

Flexible CO2 Laser Treatment for Subglottic Stenosis.

Objectives: To assess the efficacy and safety of flexible fiber CO2 laser surgery for subglottic stenosis and to present retrospective experience of 14 patients treated with flexible fiber CO2 laser system. To determine the characteristics, management protocols, prognostic factors, and postoperative outcomes of the sample.

Methods: Retrospective review of patients with subglottic stenosis undergoing flexible fiber CO2 laser surgery at the tertiary medical center.

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.

Treatment of seborrheic keratosis in bilateral external auditory canal using fiber CO2 laser.

In this article, we report a 33-year-old female patient with lesions of bilateral external auditory canals who was treated using fiber CO2 laser without canaloplasty. Histopathological examination confirmed the diagnosis of irritated type seborrheic keratosis, which is rare in external auditory canal. Twelve months after the treatment, the patient showed no signs of recurrence.

Role of nasal problems on positional and nonpositional obstructive sleep apnea.

Objectives: This study aims to examine the relationship between nasal pathologies and positional (PP) obstructive sleep apnea (OSA) or nonpositional (NPP) OSA.

Objective: To assess the histopathological effects of parylene C (PC) (poly-chloro-p-xylylene) in the inner ear.

Methods: Nine adult Dunkin Hartley guinea pigs (500-600 g) were included in the study. PC pieces were inserted into the cochlea in the right ear of the animals (study group).

Auditory brainstem implant in postlingual postmeningitic patients.

Objectives/hypothesis: The aim of this study was to evaluate outcomes of postlingual postmeningitic patients who received an auditory brainstem implant (ABI).
