OBJECTIVE To report hearing results using a titanium ossicular replacement prosthesis during canal wall down mastoidectomy with tympanoplasty to treat cholesteatoma. DESIGN Retrospective medical record review. SETTING Referral university hospital. PATIENTS Patients with cholesteatoma treated with primary or revision canal wall down mastoidectomy with tympanoplasty in a single stage. Patie...

Introduction: Chronic otitis media (COM) has been broadly classified into mucosal and squamous subtypes. COM types are associated with erosion of the ossicular chain. The aim of the present study was to correlate the type of COM, the site of perforation/retraction, and the type of disease pathology with the pattern and degree of ossicular chain necrosis.   Materials and Methods: A prospecti...

Malformations of the middle ear are classified as minor and major malformations. Minor malformations appear with regular external auditory canal, tympanic membrane and aerated middle ear space. The conducting hearing loss is due to fixation or interruption of the ossicular chain. The treatment is surgical, following the rules of ossiculoplasty and stapes surgery. In major malformations (congeni...

The surgical results of ossicular chain reconstruction using a hydroxyapatite prosthesis were evaluated in 106 ears of 101 patients who were followed up for > 5 years. Successful reconstruction was defined as: (1) postoperative air-bone gap of </= 20 db; or (2) postoperative air conduction better than 40 db; or (3) hearing gain better than 15 db. Success in hearing was obtained in 63/106 ears (...

In conductive hearing loss caused by otosclerosis stapes, surgery is the generally accepted treatment of choice. Since the introduction of stapes surgery in the 1950’s many different approaches have been developed. All modern procedures aim at reconstruction of a functional, mobile ossicular chain and adequate sound transfer at the stapes footplate. In the last two decennia small fenestra stape...

Objective This study aimed to compare hearing and anatomical outcomes after ossicular chain reconstruction with titanium or hydroxyapatite prostheses. Methods In this study, patients who underwent tympanoplasty and ossicular chain reconstruction with titanium or hydroxyapatite prostheses at a university hospital from January 2007 to February 2013 were retrospectively reviewed; they had a mini...

Objectives. Tutoplast processed human cadaveric ossicular allografts are a safe alternative for ossicular reconstruction where there is insufficient material suitable for autograft ossiculoplasty. We present a series of 7 consecutive cases showing excellent air-bone gap closure following canal-wall-down mastoidectomy for cholesteatoma and reconstruction of the middle ear using Tutoplast process...

Acoustic reflex is a sensitive indicator of middle ear lesions when the tympanic membrane is intact and tympanometry is normal. Acoustic reflex is not usually observed in conductive hearing loss caused by disruption of the ossicular chain including ossicular discontinuity and fixation. Ossicular disruption can show at least partially intact acoustic reflex under a certain condition. Moreover, o...

OBJECTIVE Ossicular chain disruption in children leads to conductive hearing loss. Few studies have focused on factors influencing successful results in pediatric ossicular chain reconstruction (OCR). We aim to determine whether demographic or surgical factors affect hearing outcomes in pediatric OCR. METHODS We conducted a retrospective chart review of 120 patients undergoing OCR at our inst...

Cartilage tympanoplasty is an established procedure for tympanic membrane and attic reconstruction. Cartilage has been used as an ossiculoplasty material for many years. The aim of this study was to evaluate hearing results of costal cartilage prostheses in ossicular chain reconstruction procedures in subjects operated on for middle ear cholesteatoma and to determine the presence of prognostic ...
