AbstractThe effect on tinnitus in 110 patients undergoing translabyrinthine vestibular nerve section is presented. The effect on tinnitus of vestibular and cochlear nerve section (VCNS) together and vestibular nerve section (VNS) alone was studied. The number of patients improved with VCNS (61 per cent) was slightly better than with VNS alone (49 per cent). VNS alone worsened tinnitus more often than VCNS. Age, side involved, sex, etiology of vertigo, severity of tinnitus, interference with sleep and activities, slope of the pre-operative audiogram, and magnitude of the hearing loss had no value in predicting the change in tinnitus following either VNS or VCNS.

AbstractIntroduction:Vestibular nerve section is a highly effective procedure for the control of vertigo in patients with Ménière's disease. However, hearing loss is a possible complication. If hearing loss occurs after vestibular nerve section, magnetic resonance imaging should make it possible to establish the presence or absence of an intact cochlear nerve.Method:Case report and review of the world literature concerning cochlear implantation after vestibular nerve section.Case report:We present a patient who developed subtotal hearing loss after vestibular nerve section. Magnetic resonance imaging was used to verify the presence of an intact cochlear nerve, enabling successful cochlear implantation.Conclusion:To our knowledge, this is the first reported case of cochlear implantation carried out after selective vestibular nerve section. Given recent advances in cochlear implantation, this case indicates that it is essential to make every effort to spare the cochlear nerve if vestibular nerve section is required. If hearing loss occurs after vestibular nerve section, magnetic resonance imaging should be undertaken to establish whether the cochlear nerve is intact.

The rationale for operations on the saccus and vestlbular nerve in patients incapacitated by Meniere's disease as a replacement for total labyrinthectomy, has been the expectancy that less radical procedures will protect these patients from total auditory incapacity. Aware of postoperative hearing losses in some patients after 3 years, we have studied the results in 21 Shambaugh saccus decompression (SD) and 29 middle fossa vestibular nerve section (VNS) operations, in order to assess the claims made for these procedures. We found that while control of vertigo was similar to that reported elsewhere, worse hearing (AAOO criteria) developed in many cases. With SD this increased from 14% at 1 year to 58% at 10 years, and with VNS it increased from 17% at 1 year to 48% at 10 years, when the worse preoperative audiogram was used. Only 17% of SD and 11% VNS ears with serviceable best preoperative hearing had retained this at 10 years. Nineteen percent developed aud iometric evidence of contralateral disease during the first 10 postoperative years. It is concluded that although, regrettably, neither of these surgical therapies appears to have the capability of preventing the progress of hearing loss, the reallty of bllateral disease justifies the continued use of SD or VNS by adequately trained surgeons.

✓ The late course of preserved hearing and tinnitus following retrosigmoid transmeatal surgery for acoustic neurilemoma is reported. Over a period of 5 years, useful hearing was preserved in 15 patients after preservation was attempted in 42 patients. In five patients the hearing was better than the preoperative level; in three it was worse. Three patients developed delayed worsening and fluctuations of hearing in the surgically treated ear during a median follow-up period of 2½ years. While the exact reason for such worsening was not clear in two patients, in one patient it appeared that the muscle graft placed in the internal auditory canal after tumor resection resulted in fibrosis and compromise of the cochlear nerve. The causes of delayed worsening of hearing in the absence of tumor recurrence are analyzed, and possible treatment and methods of prevention of worsening are suggested. In six patients, tinnitus persisted after surgery in the ear with successful preservation of hearing, but hearing was not worsened and the tinnitus was not bothersome to the patient. In one patient with preoperative tinnitus, hearing was not preserved and tinnitus persisted sufficiently to necessitate re-exploration and cochlear nerve section.

Ménière's Disease

In 1985 the American Academy of Otolaryngology—Head and Neck Surgery Committee on Hearing and Equilibrium established revised guidelines for reporting treatment results for Menière's disease. Since then little Information regarding the newly adapted criteria and their effects on the evaluation process has appeared. Thus we compared the results of different surgical procedures for Menière's disease using both the 1985 and 1972 guidelines. One hundred nine surgical procedures from 1969 to 1985 were reviewed. Six different surgical procedures were evaluated: The Cody-Tack, cochleosacculotomy, endolymphatic mastoid shunt, endolymphatic subarachnoid shunt, translabyrinthine vestibular nerve section, and transcanal labyrinthectomy. Results show that 68% of patients who had a Cody-Tack procedure continued to have vertiginous episodes in the same freguency postoperatively. Hearing was worse in 17 of these 25 patients. Of the patients who had a eochleosacculotomy, most had significant control of their vertiginous symptoms, but 10 patients had greater than 10 dB hearing loss postoperatively. Patients who had an endolymphatic mastoid shunt performed had better results when the 1972 guldllnes were applied. In this group, the 1985 guidelines indicate that only 35% of the patients had significant relief of their vertiginous symptoms and 47% had hearing loss greater than 10 dB postoperatively. Six of the seven patients who underwent an endolymphatic subarachnoid shunt obtained significant relief of their vertiginous episodes, but hearing loss was more than 10 dB In four patients. Those patients who had either a labyrinthectomy or a translabyrinthine vestibular nerve section had relief of their vertiginous episodes. We conclude that the new guidelines appear to be superior to the 1972 guidelines for reporting results for the treatment of Menière's disease.

Background: In this study, optic coherence tomography (OCT) examination was performed to check whether there was any interaction between ophthalmic axonal structures in unilateral tinnitus patients, and the relationship between optic nerve thickness and cochlear nerve thickness was evaluated. Objective: The aim of the study was to evaluate the relatioship between hearing loss, tinnitus, and nerve thicknesses. Study Design: Prospective study. Setting: Tertiary referral university hospital. Patients: The study included 88 patients with unilateral tinnitus, for which no organic cause could be found in physical examination, psychiatric evaluation, or with imaging methods. Study groups were formed of the tinnitus side and control groups were formed of the healthy side as follows: Group 1 (Non-tinnitus side normal hearing values – n = 30), Group 2 (non-tinnitus side minimal hearing loss – n = 27), Group 3 (non-tinnitus side moderate hearing loss – n = 31), Group 4 (tinnitus side normal hearing values – n = 25), Group 5 (tinnitus side minimal hearing loss – n = 25), and Group 6 (tinnitus side moderate hearing loss – n = 38). Intervention: Retinal nerve fiber layer (RNFL) thickness was evaluated with OCT, and the cochlear nerve cross-sectional area was evaluated with MRI. Main Outcome Measures: RNFL measurements were taken with OCT from the subfoveal area (RNFL-SF) and 1.5 mm temporal to the fovea (RNFL-T µm) and nasal (RNFL-N µm) sectors. On MRI, 3 measurements were taken along the nerve from the cerebellopontine angle as far as the internal auditory canal, and the mean value of these 3 measurements was calculated. Results: When the groups were evaluated in respect of cochlear nerve thickness, a significant difference was seen between Group 1 and both the groups with hearing loss and the tinnitus groups. In the subgroup analysis, a statistically significant difference was determined between Group 1 and Groups 3, 4, 5, and 6 (p = 0.013, p = 0.003, p < 0.001, and p < 0.001, respectively). When the groups were evaluated in respect of the RNFL-SF (µm), RNFL-T (µm), and RNFL-N (µm) values, the differences were determined to be statistically significant (p < 0.001 for all). In the correlation analysis, a negative correlation was determined between hearing loss and cochlear nerve diameter (r: −0.184, p = 0.014), and RNFL-N (r: −0.272, p < 0.001) and between tinnitus and cochlear nerve diameter (r: −0.536, p < 0.001), and RNFL-T (r: −0.222, p < 0.009). Conclusion: The study results clearly showed a relationship between cochlear nerve fiber thickness and hearing loss and the severity of tinnitus in cases with unilateral tinnitus and that there could be neurodegenerative factors in the disease etiology. A similar relationship seen with the RNFL supports the study hypothesis.
