Post-traumatic cholesteatoma of the external auditory canal is a rare condition which is not mentioned in any of the American or British otological reference works. Three cases are described, and the pathogenesis, management, and medico-legal implications discussed.
Surgical intervention is considered for patients whose disabling vertigo fails to respond to appropriate medical therapy. Topics discussed in this article include indications, preoperative assessment, and surgical techniques. Fifteen case studies supplement the text, followed by a discussion.
Preservation of the facial nerve during acoustic neuroma resection may be enhanced by the use of intraoperative electrical stimulation. Although stimulation of the extratemporal facial nerve is an effective and established procedure, anatomic differences of the intradural facial nerve and its microenvironment demand more exacting stimulus protocols. The… (More)
Hemangiomas involving the posterior bony external auditory canal and adjacent tympanic membrane, although rare, do appear to be a specific disease entity of the human external auditory canal. To date it has been reported in two males in their sixth decade of life. This third case in the world literature, which is reported here, appears to confirm the… (More)
This is an analysis of 1,024 primary cases of mastoid surgery for cholesteatoma operated upon during a ten-year period at the Otologic Medical Group, Inc. Our philosophy of management of the mastoid in these cases has been as follows: 1) avoid an open mastoid cavity when possible; 2) perform the operation in two stages if necessary; 3) reexplore the mastoid… (More)
Following disarticulation of the stapes from the oval window, the free edge of the adult human stapes was examined with the scanning electron microscope. Regions of the articulating surface of the rim were examined and found to vary considerably. Anterior, posterior, and lateral ligaments are described, each with tympanic, intermediate, and lateral… (More)
The use of intratympanic gentamicin is currently a popular and easily performed office procedure for the conservative treatment of the Meniere's disease patient who has failed medical therapy or who is not a candidate for surgical therapy. The procedure provides excellent control for the symptom of vertigo. Despite this success, there remains a significant… (More)
The objective of surgical management of acoustic tumors is to remove them entirely and preserve facial nerve function and hearing when possible. A dilemma arises when it is not possible to remove the entire tumor without incurring additional neurologic deficits. Twenty patients who underwent intentional incomplete surgical removal of an acoustic neuroma to… (More)
Current techniques for ossicular reconstruction include ossicular autografts and homografts, and plastic and ceramic prostheses. Experimental testing of ceramic materials has led to the development of a nonporous, bioactive form of glass ceramic (Ceravital) for tympanoplastic reconstruction. To determine the clinical usefulness of these implants, Ceravital… (More)
Advances in neurotologic diagnosis and surgery has pointed to the need for a complete reassessment of the relationship and significance of the jugular bulb and sigmoid sinus is discussed and selected temporal bone sections presented to illustrate the varying locations of the jugualr bulb. Considerations in differential diagnosis are presented and examples… (More)
