BACKGROUND: Factors related to surgical outcomes of type I tympanoplasty for tympanic membrane (TM) perforation in children are controversial. OBJECTIVES: To investigate factors related to anatomical results of type I tympanoplasty for TM perforation 1 year after surgery. MATERIAL AND METHODS: We examined 68 ears. Anatomical results were determined based on the presence or absence of re-perforation, atelectasis, and otitis media with effusion...

BACKGROUND: To ensure that subjective tinnitus patients develop positive attitudes toward tele-audiology. AIMS/OBJECTIVES: This study investigates the appropriateness of the internet-based software in patients with subjective tinnitus. MATERIAL AND METHODS: Patients between the ages of 19 and 59 applying to the clinic with the subjective tinnitus filled in Tinnitus Handicap Index (THI) and Coronavirus Anxiety Scale (CAS). Visual Numeric Scale (VNS) was applied to the patients to complaint of tinnitus...

BACKGROUND: Clinically, we find that tinnitus patients often have hearing loss. According to the most accepted mechanism of tinnitus, that is, the spontaneous discharge and abnormal synchronization of neurons after afferent reduction, tinnitus frequency is closely related to the frequency of hearing loss. OBJECTIVE: The purpose of this study was to investigate the correlation of tinnitus pitch with the frequency of hearing loss. MATERIALS AND METHODS: A total of 500 patients with unilateral or bilateral chronic tinnitus were enrolled in this study...

BACKGROUND: Follow-up of cochlear implant effectiveness is mainly focused on 3 years postoperatively, and studies with more than 5 years of observation are rare, especially for local Chinese brands. OBJECTIVES: Nurotron (Chinese domestic cochlear implant brand) CI recipients who participated in the clinical trial in 2009 were followed-up for 10 years prospectively, providing data to guide doctors and patients. MATERIAL AND METHODS: From December 2009 to April 2010, 57 subjects underwent Nurotron Venus CI surgery at multiple-centers, and were continued to be followed up and assessed at 1, 2, 3, 4, 5, and 10 years after switch on...

BACKGROUND: Inflammatory conditions such as chronic otitis media (COM) can cause irreversible impairments in the microarchitecture and functions of the incus, which subsequently leads to conductive hearing loss. OBJECTIVES: To investigate bone mineral density (BMD) of the incus body (IB) and long process (ILP) on preoperative temporal CT in COM patients with and without incudo-stapedial joint discontinuity (ISJD), and also to determine the association between BMD values and the postoperative air-bone gap (ABG) in the ISJD group...

BACKGROUND: Large Language Models (LLMs) might offer a solution for the lack of trained health personnel, particularly in low- and middle-income countries. However, their strengths and weaknesses remain unclear. AIMS/OBJECTIVES: Here we benchmark different LLMs (Bard 2023.07.13, Claude 2, ChatGPT 4) against six consultants in otorhinolaryngology (ORL). MATERIAL AND METHODS: Case-based questions were extracted from literature and German state examinations...

INTRODUCTION: Cochlear implant (CI) is a viable option of treatment for older patients with severe to profound deafness in resource-rich countries. Implantation is limited in developing countries. OBJECTIVE: To review factors and outcomes of elderly patients that underwent CI in a pioneer centre in a developing country. MATERIAL AND METHODS: An observational retrospective review of patients older than 60, implanted between 2005 to 2020. RESULTS: Eleven patients were included...

BACKGROUND: Studies of risk factors for middle ear cholesteatoma surgery using population-based data are lacking. OBJECTIVES: To investigate the risk factors for cholesteatoma surgery in adults based on population data from Korea. MATERIALS AND METHODS: For this retrospective study, we used Korean National Health Insurance Service National Sample Cohort data. Patients who were 20 years or older and underwent mastoidectomy from 2006 through 2015 under the diagnostic codes of cholesteatoma were defined as patients with middle ear cholesteatoma surgery...

BACKGROUND: There are few adequate randomized clinical trials directly comparing the therapeutic options of primary laryngectomy (pLE) vs. primary radio(system)therapy (pR(S)T) in patients with locally advanced laryngeal and hypopharyngeal carcinoma and thus little clear scientific evidence to decide which patients will benefit most from which procedure. AIMS/OBJECTIVES: Aim was to compare survival between the therapeutic options and to learn from the limitations of this study, especially in the context of improved clinical assessment...

BACKGROUND: Recycling of synaptic vesicles plays an important role in vesicle pool replenishment, neurotransmitter release and synaptic plasticity. Clathrin-mediated endocytosis (CME) is considered to be the main mechanism for synaptic vesicle replenishment. AP-2 (adaptor-related protein complex 2) and myosin Ⅵ are known as key proteins that regulate the structure and dynamics of CME. OBJECTIVE: This study aims to reveal the spatiotemporal expression of AP-2/myosin Ⅵ in inner hair cells (IHCs) of the mouse cochlea and its correlation with auditory function...
