“…Loss of cerebrospinal fluid (CSF) is another of the possible reasons of contralateral hearing loss, especially during the acoustic neuroma surgery [9]. In normal conditions the pressures of CSF, endolymph and perilymph are equal.…”

We performed a review of the VS operated in our institution between 2004 and 2015, finding a total of 185 cases. Four of these patients developed a contralateral SNHL after VS surgery (Table 1). They were 3 men and 1 woman, with an average tumour size of 19,5 mm (range 7,8-30mm). Three of them were operated by a retrosigmoid approach, and the other one by a translabyrinthine approach. At the time of diagnosis of the VS, 2 patients had normal hearing (pure tone average (PTA): 20 and 22 dB) and 2 has mild hearing loss (PTA: 26 and 40 dB). After surgery all patients developed a complete hearing loss in the operated ear. The median time of appearance of the contralateral SNHL was 16 months (range 2-54 months) with an average of hearing loss in the contralateral ear at the moment of diagnosis of 46dB. Moreover, 3 patients developed tinnitus in the contralateral ear and 2 of them developed also episodic vertigo. AbstractContralateral sensorineural hearing loss after vestibular schwannoma (VS) resection has been described, resulting in a severe complication, especially if hearing preservation in the operated side was not a reachable outcome. There exist several theories that would explain this complication, without any guideline of treatment established. We report four patients treated in our institution who developed a severe contralateral SNHL after surgery. After medical treatment only one patient recovered hearing (moderate SNHL) and the other 3 presented a severe SNHL. Cochlear implant was the only treatment of choice in two of them.

“…Contralateral hearing disturbance after acoustic neuroma surgery is extremely rare and its association with contralateral facial palsy is almost unheard of with the last report in 1983 [1]. Till date, literature review reveals only 14 patients with contralateral hearing loss after VS surgery [1], [2], [3], [4], [5], [6], [7], [8], [9].…”

“…The other contributory factors could be long hours of surgery, intra operative hypotension and bleeding that can aggravate the vasospasm. The importance of maintaining normal blood pressure during VS surgery to preserve auditory function is emphasized [9]. Uncontrolled blood pressure, diabetes and sympathetic over activity can also contribute to the vascular hypothesis.…”

“…At least 12 instances of contralateral hearing loss have been documented after acoustic neuroma surgery. 31 Drilling of the mastoid can temporarily affect both the ipsilateral and contralateral hearing function and contribute to HFHL. 5,12,19,36 In addition, a lower number of patients had a change in pure tone audiometry at 4 kHz compared to 8 kHz in both the ipsilateral and contralateral ears.…”

S enSorineural hearing loss after microvascular decompression (MVD) has a reported incidence of 1%-23.8% when performed for trigeminal neuralgia (TGN), 1.5%-4.2% for glossopharyngeal neuralgia (GPN), and 22% for geniculate neuralgia (GN). 21,24,25,27 Because of the proximity of the cranial nerve VIII to cranial nerves decompressed during the procedure, the auditory nerve in many patients is often stretched or damaged, resulting in hearing impairment. Although sensorineural hearing loss after MVD is frequently documented and well understood, high-frequency hearing loss (HFHL) is currently not well recognized. HFHL has been recently reported after MVD for hemifacial spasm (HFS). . disclosure The authors report no conflict of interest concerning the materials or methods used in this study or the findings specified in this paper. obJect The primary aim of this study was to evaluate the incidence and discuss the pathogenesis of high-frequency hearing loss (HFHL) after microvascular decompression (MVD) for trigeminal neuralgia (TGN), glossopharyngeal neuralgia (GPN), or geniculate neuralgia (GN). methods The authors analyzed preoperative and postoperative audiogram data and brainstem auditory evoked potentials (BAEPs) from 93 patients with TGN, 6 patients with GPN, and 8 patients with GN who underwent MVD. Differences in pure tone audiometry > 10 dB at frequencies of 0.25, 0.5, 1, 2, 4, and 8 kHz were calculated preoperatively and postoperatively for both the ipsilateral and the contralateral sides. Intraoperative monitoring records were analyzed and compared with the incidence of HFHL, which was defined as a change in pure tone audiometry > 10 dB at frequencies of 4 and 8 kHz. results The incidence of HFHL was 30.84% on the side ipsilateral to the surgery and 20.56% on the contralateral side. Of the 47 patients with HFHL, 20 had conductive hearing loss, and 2 experienced nonserviceable hearing loss after the surgery. The incidences of HFHL on the ipsilateral side at 4 and 8 kHz were 17.76% and 25.23%, respectively, and 8.41% and 15.89%, respectively, on the contralateral side. As the audiometric frequency increased, the number of patients with hearing loss increased. No significant postoperative difference was found between patients with and without HFHL in intraoperative BAEP waveforms. Sex, age, and affected side were not associated with an increase in the incidence of hearing loss. coNclusioNs High-frequency hearing loss occurred after MVD for TGN, GPN, or GN, and the greatest incidence occurred on the ipsilateral side. This hearing loss may be a result of drill-induced noise and/or transient loss of cerebrospinal fluid during the course of the procedure. Changes in intraoperative BAEP waveforms were not useful in predicting HFHL after MVD. Repeated postoperative audiological examinations may be useful in assessing the prognosis of HFHL.
