“…The degree of hearing impairment in the contralateral ear varied from mild to profound SNHL; including mild, 22 , 25 , 30 moderate, 3 , 20 , 22 , 25 , 26 moderate to severe, 3 , 22 , 25 severe, 3 , 4 , 8 , 20 , 24 , 26 - 28 and profound 6 , 7 , 21 , 25 , 29 degree of hearing loss. It has been suggested that hearing thresholds before vestibular schwannoma surgery could be regarded as an important factor to predict CoHL outcomes following tumor removal.…”

Background: Progression of contralateral hearing loss following otologic and neuro-otologic surgeries is a distressing and rare complication. The aim of this study was to systematically review the suspected etiologies and audiological findings in adults who experienced contralateral hearing loss. Methods: PubMed/MEDLINE, PsycINFO, CINAHL, ISI Web of Science, Cochrane Library, EMBASE, and Scopus databases were searched for this scoping review. The current review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. No limits were placed on language or year of publication. Results: Of a total of 46 studies, 43 studies met the inclusion criteria reporting contralateral hearing loss. The included studies were classified into 3 different categories: contralateral hearing loss after skull base surgeries (n = 21), contralateral hearing loss after middle ear surgeries (n = 17), and contralateral hearing loss after traumatic lesions (n = 5). The cerebrospinal fluid leakage and drill-generated noise were reported as the most reported etiology of contralateral hearing loss following skull base and middle ear surgeries, respectively. The onset of contralateral hearing loss varied from immediately to 18 months after surgery. The severity of contralateral hearing loss varied from a slight to a profound degree of hearing loss. Conclusion: Our results highlighted that contralateral hearing loss should be considered following the skull base and middle ear surgeries. Furthermore, this rare complication should be noticed after traumatic lesions.

“…In our electronic database, there were multiple pure-tone audiogram measurements per patient. Since, as mentioned earlier, subclinical and pronounced contralateral hearing loss after surgery was detected in several patients, [17][18][19][20][21][22][23][24][25][26][27][28] the last measurement directly before therapy and the most recent puretone audiogram after therapy were used for the comparison. For patients under the wait-and-scan strategy, the most recent puretone audiogram was used for analysis.…”

“…There are case reports documenting contralateral hearing loss after surgical removal of VSs. 17-26 Furthermore, Walsted et al 27,28 demonstrated in 2 prospective studies that more than half of their patients had a small threshold increase after VS surgery, which might be subclinical. Probably the most accurate explanation for this phenomenon is intraoperative loss of CSF, which leads to decreased pressure of CSF and, via the cochlear aqueduct, also of the perilymph.…”

Objective The aim of this study was to investigate the contralateral hearing of patients with sporadic vestibular schwannoma (VS). Study Design Retrospective cohort study. Setting Pure-tone audiograms of the contralateral ear from patients with a wait-and-scan strategy were compared to the ones who received therapy. Due to a possible bias caused by the therapy, hearing thresholds before and after radiotherapy or surgery were compared separately with the wait-and-scan group. Methods From 1979 to 2017, 508 patients with sporadic VS could be included in the study. Of these, 240 received regular controls in the sense of wait-and-scan, 72 underwent radiotherapy (63 audiograms before and 43 after radiotherapy), and 196 had a surgery (186 audiograms before and 146 after surgery). Age-normalized hearing thresholds of the contralateral ear from patients with a wait-and-scan strategy were compared to ones who received therapy. In addition, hearing thresholds were compared to norm values. Results There was no evidence for a difference in the contralateral hearing of patients with sporadic VS between the wait-and-scan and therapy groups. The mean difference of hearing thresholds in our sample to norm values was found to be larger for the high frequencies and more pronounced in male patients. Conclusion There was no evidence for a difference in the contralateral hearing loss of patients with sporadic VS between the wait-and-scan and therapy groups. However, there was some indirect indication of poorer contralateral hearing in all patients with sporadic VS compared to normative values.

“…Sanna modified the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) grading scheme to reflect more accurately what kind of hearing is being preserved, and reported that class A or B was obtained in 6.8% of the middle cranial fossa approach patients and in 16.7% of the retrosigmoid approach patients, while the figures were 32.2% and 31.3%, respectively, when the AAO-HNS system was applied ( Sanna et al., 2004 ). Even contralateral hearing loss and facial paralysis have been associated with excessive loss of cerebrospinal fluid ( Lustig et al., 1995 , Shuto et al., 2011 , Warade et al., 2016 ). New tinnitus also appeared postoperatively in 39.8% of VS patients ( Levo et al., 2000c ).…”

Vestibular schwannoma (VS) is a slow-growing benign neoplasm. There has been an evolution in the management of VS from active treatments (microsurgery and stereotactic radiotherapy) to conservative management (wait and scan). Regular MRI scanning is necessary to monitor tumor progression. Conservative management causes significantly less complications and offers a higher quality of life compared with active treatments. The mean growth rate of VS varies from 0.4 to 2.9 mm/year, and spontaneous shrinkage is observed in 3.8 percent of tumors during observation. If significant growth occurs, active treatment is considered. Significant growth is defined as an increase of at least 3 mm in the largest extrameatal diameter in any plane between the first and last available scans. The vestibulocochlear nerve is surrounded by cerebrospinal fluid, which provides natural contrast for MRI; thus, gadolinium may not be needed to detect VS. Specific sequences have high sensitivity, specificity, and accuracy for detection of progression. Hypointense signal in the ipsilateral inner ear fluid might be a useful sign to distinguish VS from meningioma. In this paper, we summarize the current status of research on conservative management and non-contrast MRI for the detection of VS.
