摘要:

The history of implants in otology is reviewed. Currently available biocompatible ossicular implants are described, and a survey of their use by members of the American Otological Society and the American Neurotology Society is reported.

摘要:

Fifteen percent of patients who have had an acute episode of Bell's palsy will be left with debilitating facial dysfunction.1,2This chapter describes our approach to managing a variety of hypo- and hyperkinetic disorders caused by injury and faulty regeneration of the facial nerve, using electromyographic rehabilitation (EMGR) (13 patients), Oculinum toxin injection (14 patients), or surgical reanimation (72 patients). Improvement was noted after EMGR in 12 of 13 patients (92%), all 14 patients treated with Oculinum experienced temporary improvement, and improvement was noted in 66 of 72 patients who underwent surgery (92%). The indications, techniques, and results of these three rehabilitative methods are discussed.

摘要:

The senior author has performed shunt procedures routinely for medically refractory cases of Meniere's disease starting in 1964 and ending in 1984. Five hundred and sixty-eight consecutive patients were operated on and followed from 1970 to 1984. Combining the cases of C. G. Jackson, there have been a total of 676 procedures done at the Otology Group. Initially endolymphatic-subarachnoid (ES) shunts were used, then endolymphatic-mastoid shunts (EM), and recently, the Denver valve has been employed. No significant difference between these procedures was noted in the control of vertigo or stabilization of hearing. Successful resolution of vertigo occurred in less than 60%. Sac surgery at the Otology Group, therefore, has been abandoned in favor of vestibular nerve section for the surgical management of medically refractory Meniere's disease with disabling vertigo.

摘要:

This paper describes central and peripheral eustachian tube function in relation to tympanoplasty. Central obstruction of the eustachian tube at the pharyngeal orifice is frequently correctable and is not a contraindication to tympanoplasty, whereas chronic cicatricial peripheral obstruction of the eustachian tube at the isthmus is a contraindication to tympanoplasty. These findings are based on tubal patency pressure studies measured with a mercurial manometer with the patient performing the Valsalva maneuver, with catheterization of the eustachian tube, and with politzerization.If the patient can autoinflate the middle ear and if the eustachian tube will open with politzerization, then the likelihood exists that there is no peripheral obstruction of the eustachian tube and you have a good candidate for tympanoplasty.When there is a perforation of the ear drum, the best test for eustachian tube function is microscopic examination of the middle ear mucosa. If the middle ear mucosa is perfectly normal, then you know that you have good eustachian tube function and can proceed with the tympanoplasty.

摘要:

Idiopathic sudden sensorineural hearing loss remains one of the major unsolved otologic emergencies. In this paper the most important recent clinical literature is reviewed, a new method of clinical staging is presented, and unexplored potential treatrments are presented. The method of clinical staging presented here is based on four elements represented by the acronym HEAR. The individual elements of the staging are hearing threshold (H), elapsed time from onset (E.), audiogram shape (A), and related vestibular symptoms (R). Insufficiently explored potential treatments of sudden hearing loss include antiviral drugs, rheologic agents, and free radical scavengers.

摘要:

The results of 11 years experience with 1,577 otologic surgical procedures performed in The Ear & Nose-Throat Clinic, P.A. in Little Rock, Arkansas, a freestanding outpatient surgical setting, are analyzed and compared to 703 hospitalized inpatient cases performed during the same time period. This study includes tympanoplasty, stapedectomy, mastoidectomy, labyrinthectomy and other otologic procedures. Analysis of results in these cases compares hearing results, graft take rates and the occurrence of complications in both the outpatient and inpatient settings. No significant differences are seen between the results or complications in these settings, thus supporting the use of outpatient surgical settings for most standard otologic procedures.
