摘要:
A series of 23 patients with glomus tumors of the temporal region, treated surgically at the ENT Department, University of Zurich, Switzerland from 1970 to 1977, is presented. A system of classification as to tumor size is described with tympanic, tympanomastoid, infralabyrinthine and intracranial tumors categorized as types A,B, C, and D respectively. A majority of tumors, 12 of 19 were infralabyrinthine (type C), and a surgical approach featuring permanent anterior displacement of the facial nerve, an cavity obliteration, has been employed with the aim of total tumor extirpation.There were five males in this series, with a mean age 22 years younger than for the females and all having infralabyrinthine (type C) tumors.The most frequent clinical presentation included pulsatile tinnitus, hearing loss, and observable tumor mass in the ear. Fifteen of 23 patients had significant hearing loss, of varying types on the tumor side, with one presenting as sudden hearing loss, and another as progressive unilateral sensorineural loss over several years, in the absence, initially, of tinnitus.en of 23 patients with type B, C, and D tumors had cranial nerve involvement, seventh and tenth being the most frequent.Because of slow growth and tendency to multicentric origin, final conclusions cannot be made regarding treatment in such a recent series of cases. However, the impression gained suggests that radiotherapy is less effective than complete surgical excision, and that partial excision is to be avoided.

摘要:
Refinement of the techniques of ossicular reconstruction has provided satisfactory hearing results for a majority of patients with chronic ear disease. As documented in 1976', 16% of patients, those requiring a columneller type of ossiculoplasty because of absence of the malleus, did not realize the same degree of hearing improvement as with other types of reconstruction. These procedures, short and long “L-shaped” assemblies, used for patients without a malleus, resulted in a mean 27 dB bone-air gap postoperatively. The conclusion reached after comparison with the results obtained with other types of reconstruction was “… the L-shaped conductive system is less efficient than normal by the amount observed (27 dB). If these results are to be improved, a change in the method of reconstruction resulting in a more normal system may be required.” Following duplication of the aforecited report a change in the method of reconstruction used for patients with the malleus absent was instituted, but perversely creating a less normal conductive system. This paper will present the one year results of those patients in which a Plastipore prosthesis has been used as a replacement of the previously decribed method and will compare these results with those of the past technique.

摘要:
We reviewed the records of 498 primary stapedectomy cases in regard to duration of disease, age at surgery, oval window pathology, hearing results, dizziness, and tinnitus.Ninety percent of the cases in which a tissue graft had been used as an oval window covering obtained a postoperative hearing level within 10 dB of the preoperative bone conduction. Postoperative sensorineural hearing impairment occurred infrequently and was two to three times more common in cases in which Gelfoam had been used as an oval window covering as compared to tissue grafts.Postoperative dizziness of one degree or another persisted at four months in 2 percent of the cases and was a problem for the patient in two cases (0.4%). This dizziness was likewise more common in Gelfoam cases.We concluded that tussue grafts are a better covering for the oval window than Gelfoam both in regard to hearing improvement and lack of postoperative complications.

摘要:
In this report, performance intensity functions for monosyllabic materials (Pl-PB) were obtained on two groups of subject: 20 patients with eighth nerve pathology and 15 individuals with Meniere's disease. The subjects with retrocochlear involvement exhibited marked deterioration in word recognition as the speech intensity was increased beyond the level required for a maximum discrimination score. Such a dramatic breakdown, referred to as the “rollover effect,” was not seen to occur among the subjects with cochlear disorders. Hence, the Pl-PB function appears to be a valuable tool for use in the special test battery.

摘要:
Five patients with signs and symptoms of acoustic neuroma had a filling defect on positive contrast posterior fossa myelography. At surgical exploration they were found to have a vascular loop accounting for the space occupying lesion.

摘要:
The histopathological findings in the temporal bones of three patients who underwent endolymphatic subarachnoid shunt operation for Meniere's disease are reported. The postoperative follow-up period varied from three to five years. Two patients had a successful operation; the third was unsuccessful. The continuity between the mesothelial lining of the endolymphatic sac and the subarachnoid space was demonstrated in one case; no definite conclusions could be made for the other two cases. Although failure of shunt surgery was presumably due to fibrosis in the shunt area in the reported case, the human endolymphatic sac seemed to be more resistant to surgical trauma than the sac of the experimental animals.

摘要:
A series of 70 cholesteatoma patients is reported. The incidence of recurrent and residual cholesteatoma following intact canal wall mastoidectomy (ICWM) is 22%. Revision surgery is discussed, and data are presented to support performing ICWM as a revision procedure. The place of ICWM in chronic ear surgery is discussed.
