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...

BACKGROUND Hip and knee replacement are some of the most frequently performed surgical procedures in the world. Resurfacing of the hip and unicondylar knee replacement are increasingly being used. There is relatively little evidence on their performance. To study performance of joint replacement in England, we investigated revision rates in the first 3 y after hip or knee replacement according ...

Objective The purpose of this study is to evaluate our experience with endoscopic repair of ossicular discontinuity at the incudostapedial joint, with or without an intact stapes suprastructure, and present our hearing results. We classify results based on the causative pathology, the type of ossiculoplasty, and type of lesion. We demonstrate the ability to endoscopically place a total ossicula...

Vibration of tympanic membranes of the middle ear model with TORP and flat membrane made of gum were studied by means of holographic interferometry. Results were as follows. 1) As the tension of the gum became high, the amplitude decreased in low frequency. The segmental vibration was observed in low frequency as the tension became low. 2) The difference between 0.03mm and 0.06mm was not signif...

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...

A total of 20 stapedotomy and 24 stapedectomy cases were retrospectively reviewed to establish the causes of failure, and to evaluate hearing results after revision surgery. Our series included 23 male and 21 female patients. Mean age at revision time was 42 years, and the mean interval from primary surgery and revision stapes surgery was 27 months. The retrospective review of our data, reveale...

OBJECTIVE To evaluate the long-term results and predictive factors of a good outcome with the use of a total ossicular replacement prosthesis in children. DESIGN Retrospective case review. SETTING Tertiary referral center. PATIENTS The study included 114 children (116 ears). INTERVENTIONS A total of 116 ears underwent total ossicular chain reconstruction with a titanium prosthesis. Cart...

BACKGROUND Some patients with chronic middle ear disease and multiple failed revisions, who also need a hearing aid, may benefit from an active middle ear implant. An advantage of an active middle ear implant is that the ear canal is unoccluded. METHODS Following extensive experimental development in temporal bones and investigations of various locations and attachments of a Vibrant Soundbrid...
