OBJECTIVES To determine whether ossicular reconstruction (OCR) performed concurrent with tympanomastoidectomy for cholesteatoma results in significantly different hearing results when compared to OCR performed in a separate, staged procedure. STUDY DESIGN Retrospective. MATERIALS AND METHODS Study subjects were patients undergoing OCR within a 2-year period. Intervention was OCR concurrent ...
Background: Conductive hearing loss due to ossicular abnormalities occurs from many causes, including trauma, infection, cholesteatoma, surgery and congenital anomalies. Surgical reconstruction of the ossicular chain is a wellestablished procedure for repair of ossicular defects, but is still plagued by high failure rates. Underlying disease and proper sizing of prostheses are two challenges th...
OBJECTIVE Since 1993, titanium prostheses have been used in Europe as a biocompatible implant for ossicular reconstruction. More recently, the titanium ossicular prosthesis has become more widely available in the United States as a newer means of surgical restoration of hearing. We will review the hearing results of patients who have undergone tympano-ossiculoplasty using a titanium total ossic...
HYPOTHESIS The osseointegrative capacity of medical-grade bone cement can be used to improve fixation and prevent displacement of an ossicular prosthesis in a guinea pig model. BACKGROUND Successful ossiculoplasty requires a firm connection between the vibrating tympanic membrane and the inner ear. In patients requiring revision ossiculoplasty, half of failures are due to prosthesis displacem...
OBJECTIVE To assess the efficacy of partial ossicular chain reconstruction using autologous cartilage. DESIGN Prospective study (April 1, 1997, through January 1, 2008). SETTING Tertiary academic children's hospital. PATIENTS Two hundred forty-eight children (268 ears) underwent partial ossicular chain reconstruction using a shaped block of tragal cartilage interposed between the head of ...
Background: For many years, Canal Wall Down (CWD) tympanomastoidectomy has been the gold standard for treatment of cholesteatoma; however, this method has long-term complications for the patients. The Intact Canal Wall (ICW) tympanomastoidectomy has relatively lower complications, but access to the middle-ear recesses is difficult in this method. Therefore, endoscopy is used to visualize the un...
