Surgical Decompression of the Eighth Nerve for Tinnitus.

This article reports two cases of vascular decompression for tinnitus, both of which were successful. The pathophysiology of vascular compression syndromes in general and specifically eighth nerve vascular compression syndromes is reviewed. The anatomy of the anterior inferior cerebellar artery and its relationship to the eighth nerve complex is discussed in detail and the literature of vascular compression syndrome reviewed. Although no unequivocal definitive test procedure is available for preoperative diagnosis of vascular compression syndrome, the presence of the following features makes the diagnosis more likely: I-III interpeak latency abnormalities on auditory brain stem response (ABR), abnormalities of stapedius reflex, unilateral sensorineural hearing loss, ipsilateral electronystagmography (ENG) abnormalities, especially spontaneous nystagmus, and radiographic visualization of a vessel contacting the eighth nerve complex.

Management of the external auditory canal in skull base surgery.

Transtemporal approaches to the skull base are being used with increasing frequency. When the external auditory canal is transected in the course of these operations, the risk of cerebrospinal fluid fistula is created. When hearing is to be sacrificed, we use a modification of the technique developed by Rambo for closure of the external auditory canal. This technique permits a cosmetically acceptable reliable watertight closure. When hearing is to be salvaged, we use a "conchal flap technique," which prevents circumferential scarring and stenosis and permits a watertight suture closure.

Current management of esophageal foreign bodies.

Between 1972 and 1978, a total of 159 cases of esophageal foreign body were treated at the University of Minnesota Affiliated Hospitals, Minneapolis. Although coins were the most frequent offending agent in the pediatric group, meat was the most common in the entire series (60%). Eighty percent of coins were impacted in the upper esophagus, while meat impaction occurred most frequently in the distal esophagus (42%). Rigid esophagoscopy was performed in 134 patients. The foreign body was removed during esophagoscopy in 122 cases, advanced into the stomach in two cases, and not found in ten cases. In addition to esophagoscopy, when meat obstruction was suspected, several pharmacologic agents were successful in relieving the obstruction, such as parenterally administered diazepam (Valium) (8/27) and glucagon (6/14). Spontaneous passage was noted in seven cases. No cases of esophageal carcinoma were discovered in this series.
