ABSTRACT

BACKGROUND: To date, the literature directly comparing the translabyrinthine approach and retrosigmoid approach in the operation of patients with vestibular schwannoma was limited. We aimed to evaluate postoperative complications between translabyrinthine approach and retrosigmoid approach for treating vestibular schwannoma patients. MATERIAL AND METHOD: Potential publications were selected from PubMed, Web of Science and Cochrane Library. Gray relevant studies were manually searched. We set the searching time spanning from the creation date of electronic engines to February 2020. STATA version 12.0 was exerted to process the pooled data. RESULTS: A total of 9 literature included in the study, involving 2429 patients, hails from the Germany, USA, Canada, Italy, and France. Of these 2429 patients with vestibular schwannoma, there were 1628 cases from the translabyrinthine approach group versus 801 cases from the retrosigmoid approach group. The results demonstrated that the translabyrinthine approach group was associated with a lower rate of tinnitus (OR = 2.687; 95 %CI, 1.167-6.191; P = 0.02) and cranial nerve deficit (OR = 2.946; 95 %CI, 1.562-5.557; P = 0.001). And the translabyrinthine approach group was associated with a higher total resection rate (OR = 0.246; 95 %CI (0.071-0.848); P = 0.026). However, no statistic differences were found in the incidence of the near total (OR = 0.751; P = 0.351), subtotal resection (OR = 3.664; P = 0.109), postoperative facial nerve dysfunctions (OR, 0.763; P = 0.626), postoperative meningitis (OR = 2.7; P = 0.279), cerebrospinal fluid leak (OR = 1.225; P = 0.777), postoperative headache (OR = 1.412; P = 0.339), ophthalmic complications (OR = 0.87; P = 0.59), and vascular complications (OR = 2.501; P = 0.139). CONCLUSION: Based on current evidence, the translabyrinthine approach was associated with a higher rate of total resection and a lower rate of the tinnitus and cranial nerve deficit. But the risk of cranial nerve deficit was clearly affected by the preoperative status. And a translabyrintine approach could imply a complete sensorineural hearing loss, which contribute to the lower rate of postoperative tinnitus. Consequently, more evidence-based researches are needed to supplement this opinion.

ABSTRACT

BACKGROUND: Surgical decompression and conservative treatment are routinely used in the treatment of patients with malignant infarction of the middle cerebral artery (MIMCA). However, efficacy and safety are controversial. The purpose of this study is to systematically compare the clinical outcomes between surgical decompression and conservative treatment in patients with MIMCA. METHODS: This study retrieved available academic randomized controlled trials (RCTs) comparing the clinical outcomes between surgical decompression and conservative treatment in patients with MIMCA from the databases of ScienceDirect, Cochrane Library, Embase, and PubMed. The references of previous reviews and related clinical studies were manually checked to retrieve potential literature that was not involved in our electronic search results. RESULTS: A total of 7 RCTs were included in the study. The overall number of participants in the surgical decompression group was 165, whereas it was 173 in the conservative treatment group. The results revealed that the surgical decompression group was related to a lower incidence of 1-year death (odds ratio [OR], 0.192; 95% confidence interval [CI], 0.119-0.309; P < 0.001), 1-year death in patients >60 years of age (OR, 0.202; 95% CI, 0.097-0.421; P < 0.001), 1-year death in patients <60 years of age (OR, 0.145; 95% CI, 0.069-0.301; P < 0.001), 1-year death in patients treated within 48 hours of stroke onset (OR, 0.159; 95% CI, 0.090-0.282; P < 0.001), and modified Rankin Scale (mRS) score ≤3 (OR, 2.082; 95% CI, 1.185-3.658; P < 0.001). CONCLUSIONS: Based on current evidence for patients with MIMCA, decompressive surgery not only is a life-saving therapy but also reduces the incidence of mortality without increasing the risk of severe disability.
