Article Synopsis
- The study investigates how papaverine affects myringosclerosis (MS) in rats, focusing on its impact on hearing issues caused by the condition.
- Twenty Wistar albino rats were divided into four groups to test different treatments, including myringotomy, saline application, and both systemic and topical papaverine.
- Results indicated that papaverine increased the severity of MS, possibly due to its vasodilating effects that lead to higher levels of oxygen-derived free radicals, warranting further evaluation of its implications on MS.
Purpose: There is no guideline or consensus on preoperative radiologic imaging modality despite the fact that it has a vital importance in appropriate candidacy selection of cochlear implantation. We aimed to find out the role of high-resolution computed tomography (HRCT) and magnetic resonance imaging (MRI) on surgical planning, intraoperative technique in cochlear implant candidates.
Methods: The clinical charts, imagings, and operative reports of patients who underwent cochlear implant surgery at a tertiary institution were retrospectively examined.
Purpose: Pediatric population may be more prone to complications in comparison to adults because of the variability of developmental changes of paranasal sinuses and skull base. Knowledge of standard columellar distances regarding age in addition to anatomical landmarks is an important guide during functional endoscopic sinus surgery. We aimed to identify standard distances from columella and anterior nasal spine to the anterior and posterior border of frontal and sphenoid sinus ostiums and provide an objective reference graph in regard to age in children.

Methods: A total of 56 subjects were evaluated by lateral cephalometric radiography and polysomnography (PSG). The OSA diagnosis was made according to the patients' AHI.
Objective: In this study, we aimed to functionally and morphologically demonstrate the effectiveness of platelet-rich plasma (PRP) on anosmia in a mouse model of anosmia.
Study Design: Animal study.
Methods: A total of 16 male mice were included.
Objective: To identify the vertebral artery blood flow in different head positions in patients with positional vertigo with no specific diagnosis.
Methods: Patients with history of vestibular symptoms associated with changes in head position were enrolled into the study. Healthy volunteers were evaluated as control group.

Objective This study aimed to determine the value of submental ultrasonography (US) parameters for diagnostic workup among patients with obstructive sleep apnea (OSA) and to determine whether there is a correlation between US findings and the severity of OSA. Study Design Cross-sectional analysis. Setting Tertiary education hospital.
