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)...

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...

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...

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...

OBJECTIVE: To determine whether endoscopic cholesteatoma removal can be performed efficiently and safely using a curved fiberoptic-based laser. BACKGROUND: Angled instruments are required in endoscopic ear surgery to access recesses of the middle ear without extra drilling.

OBJECTIVES: In this retrospective study, we investigated the outcomes of fat graft myringoplasty (FGM) in different perforation sizes and locations. The outcomes were evaluated in terms of closure rates and audiological test results. METHODS: The study population included 172 patients who were operated between 2007 and 2012. 161 had unilateral and 11 had bilateral chronic otitis media; and 183 ears were operated by FGM. The patients were divided into two groups based on size as small and larger (size of ≤30 of TM was defined as small perforations, and size of >30% TM was defined as a medium-large perforations); and two groups based on location of perforation [anterior and other (non-anteriorly located)]...

INTRODUCTION: To reduce incidence of residual cholesteatoma following ear surgery; and to reduce the need for second look "open" mastoidectomy using endoscopic mastoidotomy. Ten-year retrospective chart review of 249 primary cholesteatoma cases (1994-2004) with a minimum follow-up of two years. The first objective was to evaluate the effectiveness of otoendoscopy in reducing the incidence of "cholesteatoma remnant" at the time of primary surgery. The second investigation was to evaluate the effectiveness of otoendoscopy in reducing the need to open the mastoid cavities during "second look operations"...

Chronic tympanic membrane (TM) perforation is one of the most common otology complications. Current surgical management of TM perforation includes myringoplasty and tympanoplasty. The purpose of this study was to evaluate the efficacy and feasibility of three dimensional (3D) porous collagen scaffolds with topically applied human umbilical cord serum (UCS) for the regeneration of chronic TM perforation in guinea pigs. To achieve this goal, we fabricated porous 3D collagen scaffolds (avg. strut diameter of 236 ± 51 μm, avg...

A cadaveric study was performed to test the hypothesis that intact-canal-wall mastoidectomy (ICWM) with otoendoscopy allows for equal or better visualization of the middle ear cavity structures when compared with canal-wall-down mastoidectomy (CWDM) with microscopy. Ten temporal bones were prepared with a reversible canal-wall-down tympanomastoidectomy technique. Five anatomic sites in each middle ear cavity (lateral epitympanum, posterior crus of the stapes, the sinus tympani, eustachian tube orifice, and round window niche) were marked with paint...
