A series of 785 bone grafts between the tympanic membrane and head of the stapes were performed between 1964 and 1998. Ears were divided into 'normal tympanic membrane', 'stage I' and 'stage II' groups, in which the averages of the last postoperative air-bone gaps were 13.2, 18.7 and 18.1 dB, respectively (revision operations included). In the same order 43%, 26% and 23% of the ears showed air-...

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 (...

Introduction: The use of ossicular graft material in ossicular chain reconstruction has significantly improved hearing results hearing after tympanoplasty and tympanomastoid surgery for chronic otitis media. Today, otologists have a wide array of tools from which to choose, but may find it difficult to know which middle ear implant works best.   Materials and Methods: A prospective study of 80 ...

INTRODUCTION Cartilage interposition grafting is commonly utilized during allograft ossiculoplasty as a way to prevent extrusion of the prosthesis through the tympanic membrane. Even with the earliest materials such as Plastipore (Xomed, Jacksonville, FL) and hydroxyapatite, use of cartilage interposition has led to lower extrusion rates without the expense of poorer hearing outcomes. Allograft...
