Effects of vestibular nerve section on sound-evoked myogenic potentials in the sternocleidomastoid muscle of monkeys

AbstractObjective:To present the profile of patients undergoing surgical treatment for vertigo at a contemporary institutional vertigo clinic.Study design:A retrospective analysis of clinical charts.Methods:The charts of 1060 patients, referred to an institutional vertigo clinic from January 2003 to December 2012, were studied. The clinical profile and long-term outcomes of patients who underwent surgery were analysed.Results:Of 1060 patients, 12 (1.13 per cent) were managed surgically. Of these, disease-modifying surgical procedures included perilymphatic fistula repair (n = 7) and microvascular decompression of the vestibular nerve (n = 1). Labyrinth destructive procedures included transmastoid labyrinthectomy (n = 2) and labyrinthectomy with vestibular nerve section (n = 1). One patient with vestibular schwannoma underwent both a disease-modifying and destructive procedure (translabyrinthine excision). All patients achieved excellent vertigo control, classified as per the American Academy of Otolaryngology – Head and Neck Surgery 1995 criteria.Conclusion:With the advent of intratympanic treatments, surgical treatments for vertigo have become further limited. However, surgery with directed intent, in select patients, can give excellent results.

Ménière's Disease

The role of vestibular nerve section (VNS) surgery in the management of Meniere's disease is considered by prospective analysis of a large series of 531 patients treated by the author over a period of 11 years. Twenty-seven percent were referred by their primary care physicians, while the rest were secondary (45.6%) or tertiary (27.3%) referrals. Overall, 62 (11.7%) Meniere's patients underwent 63 VNS procedures. This surgery was undertaken more frequently in the secondary and tertiary referral patients (14.2%) than in the primary referrals (5.5%). The retrolabyrinthine technique was the preferred approach in almost 90% of ears. The results and complications of these and other surgical options are discussed in an attempt to define the present role of VNS in intractable Meniere's disease. Vertigo was abolished after VNS in 93% of cases. Compensation was significantly impaired in 12.9%. All these patients had contralateral Meniere's disease or marked labyrinthine hypofunction. Although highly effective and associated with few postoperative complications, VNS is generally reserved for sac failures, though may be appropriate as a primary procedure in severe unilateral cases.

Objective: The aim of this study is to present a methodology of vestibular evoked myogenic potentials registered from sternocleidomastoid muscle (SCM) using skull tap stimulation (Tap-cVEMP) in a patient with cerebellopontine angle tumor (CPAT). Material and methods: A 23-year-old female with CPAT. The methodology of Tap-cVEMP is introduced. The results of VEMP is confronted with surgical information about the tumor. Results: The results of AC-cVEMP and Tap-cVEMP revealed the inferior vestibular nerve bundle to be affected by the tumor with intact superior bundle. Information obtained from VEMP was confirmed during surgery. Conclusion: Skull Tap Vestibular Evoked Myogenic Potentials (Tap-cVEMP) may be the useful method in the diagnostics of CPAT. AC-cVEMP and Tap-cVEMP may be helpful to evaluate the functional integrity of both vestibular nerve bundles providing the information about their involvement in the pathological process.
