Objective: We aimed to evaluate the clinical findings of our cochlear implant (CI) patients with otitis media with effusion (OME) and CI patients treated with ventilation tube (VT) for OME.

Methods: The medical records of patients who underwent CI surgery at Hacettepe University, Department of Otorhinolaryngology, between November 1997 and March 2023 were reviewed. Patients who had OME or VT in the implanted ear at the time of surgery were included in the study.

Morphometric Measurements of the Incomplete Partition Type II (IP-II) Cochlea and Implications on Cochlear Implantation.

Hypothesis: The objective of this study is to obtain comprehensive morphometric measurements of the incomplete partition type II (IP-II) cochlea to provide a better understanding of intracochlear anatomy and important considerations for electrode selection and insertion.

Background: IP-II is the most common bony inner ear malformation that often requires cochlear implantation. Currently, there is significant controversy on electrode selection due to a lack of research that can provide reliable, high-resolution measurements.

Setting: Tertiary referral center.

Children with Auditory Brainstem Implants: Language Proficiency and Reading Comprehension Process.

Introduction: Auditory performance and language proficiency in young children who utilize auditory brainstem implants (ABIs) throughout the first 3 years of life are difficult to predict. ABI users have challenges as a result of delays in language proficiency and the acquisition of reading comprehension, even if ABI technology offers auditory experiences that enhance spoken language development. The aim of this study was to evaluate about the impact of language proficiency on reading comprehension skills in children with ABI.

The Management of Pediatric Otitic Hydrocephalus: Case Report.

Otitic Hydrocephalus (OH) is one of the most significant life-threatening complications of otological infections. Given their low prevalence and non-specific ear symptoms, this complication requires a high index of suspicion for diagnosis. In this case report, we aim to provide an analysis of OH and describe common clinical signs and symptoms, treatment options, morbidity and mortality.

Unimodal versus bimodal auditory stimulation in inner ear malformations: Cognitive, language, and motor performance.

Purpose: New perspectives on rehabilitation options for inner ear malformations have still been studied in the literature. This study investigated the cognitive, language, and motor skills of auditory brainstem implant (ABI) users in unimodal and bimodal groups.

Methods: The motor competency of the participants was assessed with Bruininks-Oseretsky Motor Proficiency Test-2 Short Form (BOT2 SF).

Long term results of glass ionomer ossiculoplasty.

Objective: To analyze and compare the early and late post-operative results of glass ionomer bone cement (GIBC) used in ossiculoplasty.

Methods: The pre-operative, early post-operative (3 months) and late post-operative (> 2 years) audiometric findings, namely the pure-tone average (PTA), bone conduction threshold (BCT) and air-bone gap (ABG) of 40 patients who underwent GIBC ossiculoplasty for different etiologies were analyzed. Early and late results were compared.

Flocculus Herniation into the Internal Acoustic Canal in Incomplete Partition Type I: A Case Report.

In this study, we present the first case with cerebellar herniation into the internal acoustic canal in incomplete partition type I anomaly. Cerebellar herniation into the internal acoustic canal is very rare with only a few cases reported in the literature. Although it is a rare clinical situation, cerebellar herniation into the internal acoustic canal may be seen in patients with incomplete partition type I.

Hearing Loss Related to Gene Mutations in Distal Renal Tubular Acidosis.

Introduction: Distal renal tubular acidosis (dRTA) is a disease that may develop either primarily or secondarily, resulting from urinary acidification defects in distal tubules. Hearing loss may accompany primary forms of dRTA. This study aims to determine the characteristics of hearing loss due to different gene mutations in patients with dRTA.

Speech Perception and Sound Localization Skills in Inner Ear Malformations: Children With Incomplete Partition Type-II.

Objective: The present study aimed to evaluate binaural auditory skills in bimodal and bilateral pediatric cochlear implant (CI) users with incomplete partition type-II (IP-II) and to reveal the effect of IP-II on performance by comparing the results to pediatric CI users with normal cochlear morphology.

Study Design: Cross-sectional study.

Setting: Tertiary referral center.

Evaluation of the non-auditory responses in individuals with auditory brainstem implant.

Objectives: After auditory brainstem implant (ABI) surgery, stimulation of certain cranial nerves may result in a non-auditory response, and the electrodes that stimulate these nerves may be deactivated. The goals of this study are to compare the number of active electrodes in the initial activation and the last fitting, to investigate non-auditory response types and their frequency as a result of non-auditory stimulation, to compare the placements of deactivated electrodes as a result of non-auditory stimulation in the initial activation and the last fitting.

Methods: The computer software system was used to perform a retrospective analysis of the fitting data of 69 ABI users who underwent auditory brainstem implant surgery between January 1997 and January 2019.

Written language skills in children with auditory brainstem implants.

Purpose: This study aimed to assess the written language skills of children with auditory brainstem implants (ABI).

Methods: In this study, 15 children (from second to eighth grades) with ABI were evaluated for their written language abilities using a written expression skill assessment form. Five different features of written expression points were scored and analyzed, yielding a composite score for written expression skills.

X-linked deafness/incomplete partition type 3: Radiological evaluation of temporal bone and intracranial findings.

Purpose: X-linked deafness (XLD) is a rare disease, characterized by typical cochlear incomplete partition type 3 anomaly (IP-III). Accompanying hypothalamic anomalies were also recently described. The purpose of this study was to document the temporal bone and intracranial imaging findings in a series of patients with XLD with a review of the literature, to better understand this anomaly.

3 Tesla MR imaging of the large endolymphatic duct and sac anomaly with audiological correlation.

Purpose: Large endolymphatic duct and sac (LEDS) is one of the most common imaging abnormalities in congenital sensorineural hearing loss and is frequently seen with coexistent cochlear anomalies, especially incomplete partition type II. However, MRI findings of accompanying cochlear and especially modiolar dysplasias may be subtle. The purpose of this study is to evaluate the imaging findings of LEDS with high-resolution imaging at 3 T and correlate with the audiological data.

Radiological Features and Pathognomonic Sign of Stapes Footplate Fistula in Inner Ear Malformations.

Objective: Some inner ear malformations may cause recurrent meningitis, which may be fatal. The etiology is usually a stapes footplate fistula which enables microorganisms to pass into the inner ear containing cerebrospinal fluid (CSF), causing repeated attacks of meningitis. Radiological signs of the fistula are not obvious and are not reported in detail in the literature.

Computed tomography scans of all cases with congenital stapes fixation were reviewed, and cases with inner ear anomalies were taken into account.

Unilateral Facial Paralysis and Ophthalmoplegia Caused by Lower Lip Carcinoma: A Case Report.

We discuss a case of lower lip carcinoma which presented with atypical symptoms; facial paralysis, conductive type hearing loss, and ophthalmoplegia. Due to an earlier resection, no mass was evident on the primary examination. Diagnostic imaging revealed a mass originating from the lower lip, the perineural spread of the tumor along the left inferior alveolar nerve to the left infratemporal fossa and the left foramen ovale.
