An endolymphatic-mastoid Silastic shunt procedure was performed in 122 cases of Menière's disease having a mean follow-up period of three years. In accordance with American Academy of Ophthalmology and Otolaryngology 1972 criteria, there were 43 % class A, 20% class B, 21% class C, and 17% class D results. Analysis of 35 recent cases having a mean follow-up period of nine months revealed 57% class A, 25% class B, 9% class C, and 9% class D results. Sixteen percent of the patients who experienced classes A, B or C results complained of other fluctuating symptoms which were not relieved by surgery. Moreover, three new eases of otolithic crisis were found in the postoperative group. Seven of ten patients who experienced a class A or B result had either a recrudescence of their vertigo or a significant decrement in hearing in response to a postoperative salt-loading test. It is concluded that the surgical success rate decreases with time and that the procedure appears to alter the symptom complex but does not cure Menière's disease.

AbstractObjective:To evaluate hearing results following intratympanic gentamicin perfusion in patients with Ménière's disease.Materials and methods:Middle-ear perfusion of 0.4 ml of gentamicin 40 mg/ml solution was performed in Ménière's disease patients who had previously failed to respond to other medical treatment.Results:Between May 1999 and November 2005, 22 patients (mean age 58.5 years) underwent intratympanic gentamicin perfusion. Mean follow up was 30 months. At the first post-perfusion visit (four to six weeks following perfusion), three of the 22 patients (13.63 per cent) had a pure tone average improvement of at least 10 dB, 15 (68.18 per cent) showed no change and four (18.18 per cent) demonstrated a decrease in hearing of more than 10 dB. Regarding speech discrimination scores, one patient (4.54 per cent) exhibited an improvement of at least 15 per cent, 15 (68.18 per cent) showed no change and six (27.27 per cent) showed a decrease of at least 15 per cent. After long-term follow up (12–40 months following perfusion), 10 patients (45.45 per cent) showed stable hearing, and 12 (54.54 per cent) exhibited a pure tone average decrease of more than 10 dB. Six patients (27.27 per cent) showed a speech discrimination score decrease of at least 15 per cent, while 16 (72.72 per cent) had no change. Complete cessation of vertigo was reported by 20 of the 22 patients (90.9 per cent), while two (9.09 per cent) reported episodic vertigo spells.Conclusion:Intratympanic gentamicin perfusion provides effective control of vertigo in patients with Ménière's disease. However, significant hearing loss may occur immediately after perfusion; therefore, this treatment should be considered only for patients whose hearing has already been affected by the disease.

This paper discusses the use of vestibular testing to discriminate between right (n = 29) and left (n = 27) Ménière's disease. We examined reduced vestibular response (RVR), directional preponderance, and spontaneous and positional nystagmus measurements from electronystagmography, as well as the asymmetry measurements from the sinusoidal harmonic acceleration test, to determine whether multivariate logistic regression could improve upon the discrimination performance of RVR alone. We found that patients with a spontaneous or positional nystagmus often had a “recovery nystagmus”, beating in the opposite direction of that predicted for an acute lesion. When present, the direction and magnitude of such nystagmus could be used in the classification algorithm to increase the discriminatory power over RVR alone, but in these patients the rotation test asymmetry measurements were rendered useless. In the absence of spontaneous or positional nystagmus, asymmetry measurements significantly enhanced right/left discrimination. Directional preponderance was insignificant in determining the side of lesion.
