Aeration of the middle ear and mastoid in tympanoplasty.

In order to achieve a good hearing result following tympanoplasty it is necessary to maintain an aerated middle ear space. Poor Eustachian tube function is most commonly blamed in cases of failure to obtain an adequately aerated middle ear following tympanoplasty. Although this may be the true etiology in some cases, middle ear adhesions, loss of support of the posterior canal wall and inadvertent blockage of the Eustachian tube orifice by graft material may be contributing factors. Aeration of the mastoidectomy cavity is also important to prevent collapse of the posterior canal wall, retraction pockets and to insure an adequate air reserve. Surgical techniques for prevention of these complications and a means of bypassing the totally blocked Eustachian tube are discussed.

Chronic mastoiditis mimicking recurrence of nasopharyngeal carcinoma: report of a case.

A nasopharyngeal mass with cranial neuropathies usually indicates an advanced neoplastic process. We present a case of nasopharyngeal carcinoma diagnosed and treated 38 years ago. A nasopharyngeal mass recurred with cranial neuropathies and concurrent otologic infection in June, 1990. Repeated nasopharyngeal biopsies were negative with respect to tumors. Suspecting direct extension of the otologic infection, modified radical mastoidectomy was performed. The nasopharyngeal mass resolved after the surgical intervention. Spread of otologic infection from the temporal bone to the nasopharynx may be more common than was previously thought. Clinicians should modify diagnostic approaches in patients with a nasopharyngeal mass and concurrent otologic disease.

Tissue-integrated prostheses in the rehabilitation of auricular defects: results with percutaneous mastoid implants.

Functional and cosmetic rehabilitation of the severely atretic auricle poses a formidable challenge. Conventional autologous grafts for auricular reconstruction may produce inconsistent results, and revision of failed grafts is often unsatisfactory. Osseointegrated implant systems to retain auricular prostheses provide an alternative approach in rehabilitating patients with severe auricular defects. Fourteen patients were implanted with 30 osseointegrating implants for rehabilitating major auricular defects and were followed for 1 to 3.5 years, yielding 143 implant observations. Symptomatic skin reactions to the percutaneous implant were noted in 3.5 percent of the observations. Implant extrusion did not occur. This evaluation of tissue-integrated prosthetic systems suggests this approach to be an extremely reliable alternative for selected patients with major auricular defects. The technique of implanting the retention unit is readily adapted to atresia repair.

[Pneumocephalus as a complication of mastoid surgery].

Non-traumatic otologic diseases are a rare cause of Pneumocephalus. Among them few reports have been published whereas it presented following oto-surgery. The AA. communicate one of those events in a patient who presented with CSF-otorrhea, headache and disorientation after recent radical mastoidectomy. The definitive diagnosis was done by CT-scan imaging. Survey of the scarce literature on the subject, description of the clinical and diagnostic features, its possible physiopathology and surgical management.
