INTRODUCTION: Previous reports indicated that middle ear surgery might partially improve tinnitus after surgery. However, until now, no influencing factor has been determined for tinnitus outcome after middle ear surgery. OBJECTIVE: The purpose of this study was to investigate the association between preoperative air-bone gap (ABG) and tinnitus outcome after tympanoplasty type I. METHODS: Seventy-five patients with tinnitus who had more than 6 months of symptoms of Chronic Otitis Media (COM) on the ipsilateral side that were refractory to medical treatment were included in this study...

Tympanic membrane (TM) perforation is one of the most common otology complications. To date, there has not been reported TM regeneration using bioprinted scaffold. The purpose of this study was to evaluate the efficacy and feasibility of bioprinted polycaprolactone/collagen/alginate-mesenchymal stem cell (PCAMSC) scaffolds for the regeneration of subacute TM perforation. Sprague-Dawley rats were used in an animal model of subacute TM perforation. In the experimental group (n=7), bioprinted 3D PCAMSC scaffold was placed on the perforation...

BACKGROUND AND OBJECTIVES: The recent increase in the reported incidence of congenital cholesteatoma (CC) may be secondary to the widespread use of otoendoscopy as well as an increased awareness of these lesions among primary care physicians. However, little research about CC has been conducted in a large group of patients. This study aimed to analyze the clinical characteristics of CC including the annual number of patients, symptoms, age at diagnosis, stage and type of disease, surgical techniques, recurrence, and postoperative complications...

BACKGROUND: The surgical management of cholesteatoma is a controversial issue, particularly regarding intact-canal-wall mastoidectomy (ICWM) versus canal-wall-down mastoidectomy (CWDM). The current experiment compared the quality of visualization in different middle ear structures using ICWM with otoendoscopy with findings of CWDM by microscopy. MATERIALS AND METHODS: The patients diagnosed with cholesteatoma underwent tympanomastoidectomy, and then the patients selected for CWDM were included in the study (25 patients: 11 females and 14 males)...

The objective of this is to verify whether the hearing impairment caused by posterior epitympanic differed from that caused by posterior mesotympanic cholesteatomas by a cross-sectional study. We evaluated 264 ears of patients with cholesteatoma, who had not been subjected to ear surgery. Otoendoscopy and pure-tone audiometry were performed. Analyzed route involved in cholesteatoma formation: posterior epitympanic or posterior mesotympanic, air-bone gaps at 512-4000 Hz and pure-tone averages. The mean age of the patients enrolled in this study was 33...

OBJECTIVE: To determine whether middle ear cholesteatoma is associated with, sensorineural hearing loss, and whether patient age, cholesteatoma growth pattern, or, air bone gap size contribute to inner ear impairment. STUDY DESIGN: Cross-sectional comparative. SETTING: A tertiary hospital. PATIENTS: The subjects were 115 patients with middle ear cholesteatoma in one ear, and normal video-otoscopy in the contralateral ear (CLE)...

IMPORTANCE: Several classifications of cholesteatoma exist, but there are controversies about their clinical application. OBJECTIVE: To classify cholesteatomas and describe the prevalence of the subtypes. DESIGN, SETTING, AND PARTICIPANTS: A cross-sectional comparative study of 414 ears in 356 consecutive patients with middle ear cholesteatoma and no history of ear surgery treated at a tertiary hospital was conducted from March 8, 2000, to March 30, 2015...

OBJECTIVE: A pilot study was performed to investigate the utility of basic fibroblast growth factor (bFGF) in the repair of blast-induced total or near-total tympanic membrane perforations (TMPs). STUDY DESIGN: Prospective clinical study. SETTING: Tertiary university hospital. SUBJECTS AND METHODS: Patients who fulfilled the inclusion criteria were treated with 0.10-0.15 mL of bFGF solution applied directly to total or near-total TMPs once daily until the perforations closed or for a maximum of 6 months...

Middle ear cholesteatoma has been extensively studied. Theories of cholesteatoma pathogenesis involving previous tympanic membrane retraction are the most widely accepted, but the contralateral ear in patients with cholesteatoma remains unstudied. This study aimed to investigate the contralateral ear in patients with cholesteatoma, and to determine whether the characteristics of it differ according to patient age and cholesteatoma growth patterns. This study was cross sectional. We evaluated 356 patients with middle ear cholesteatoma in at least one ear, and no history of surgery, between August 2000 and March 2013...

OBJECTIVE: In this study, we developed a biocompatible and biodegradable vancomycin (VM)-eluting electrospun poly(ɛ-caprolactone) (PCL)/polyethylene oxide (PEO)/VM/PCL nanofiber mat. The purpose of this study was to evaluate the efficacy of this nanofiber mat for preventing methicillin-resistant Staphylococcus aureus (MRSA) biofilm on the ossicular prostheses and otitis media. MATERIALS AND METHODS: Fabrication of VM eluting nanofiber mat was carried out using PCL and PEO...

Myringoplasty aims to reconstruct the tympanic membrane, restoring protection to the middle ear and improve hearing. Success of Myringoplasty in terms of anatomical closure is influenced by many factors. This study focuses on the influence of size and site of tympanic membrane perforation on success rate of Myringoplasty. This is a prospective study of 60 patients who underwent myringoplasty and were then followed up for 6 months from the date of operation. Patients with dry perforation, with good cochlear reserve, intact and mobile ossicular chain, functioning Eustachian tube were selected randomly for the operation...

BACKGROUND: The performance of nationwide studies of chronic otitis media (COM) in adults has been insufficient in Korea. We evaluated the prevalence and risk factors of COM in Korea. METHODS: This study was conducted using data from the fifth Korean National Health and Nutrition Examination Survey (n = 23,621). After excluding the subjects under 20 year old and suffered from cancers, 16,063 patients were evaluated for COM. Participants underwent a medical interview, physical examination, endoscopic examination, and blood and urine test...

The objective of the present work was to enhance the effectiveness of diagnostics of cholesteatoma of the external and middle ear in the children. The study included 66 patients presenting with chronic suppurative otitis media and one child having cholesteatoma of the external auditory meatus. All the patients were examined with the use of otoendoscopy and CT of the temporal bones. It was shown that the frequent occurrence of acute suppurative otitis media, exudative suppurative otitis media, and adhesive otitis media is the risk factor of the development of cholesteatoma of the external and middle ear in the children...
