Huo Z, et al. - In this retrospective study involving 138 patients, researchers assessed the long-term hearing results of vestibular schwannoma (VS) patients in order to explore suitable surgical treatment. From January 2006 to December 2015, patients diagnosed with small and medium-sized VS with serviceable hearing were included. All patients had retrosigmoid (RSA) or middle cranial fossa approach (MFA) microsurgery and have been followed up for more than 2 years. Data reported that the mean tumor size and volume were 16.6 ± 3.4 mm and 1711.8 ± 918.5 mm³, respectively. Prognostic factors for a serviceable hearing were better preoperative hearing, shorter hearing loss period, tumors from superior vestibular nerve, and normal intraoperative I wave. For tumor removal and hearing preservation, RSA and MFA are effective and safe. Hearing loss within six months affected postoperative hearing positively. The size of the tumor, cystic variation, or extension of the internal auditory canal fundus did not affect hearing preservation.
