Hearing in patients with intracanalicular vestibular schwannomas.
This paper reports data on the spontaneous course of hearing in 156 patients with purely intracanalicular vestibular schwannomas. The mean pure tone average (PTA) was 51 dB HL and the mean speech discrimination score (SDS) 60% at diagnosis. The risk of a significant subsequent hearing loss (>or=10 dB PTA or >or=10% SDS) was 54% during 4.6 years of observation. Patients with normal speech discri...
متن کاملEndoscopic-Assisted Middle Fossa Craniotomy for Resection of Vestibular Schwannoma
Background Rates of hearing preservation following surgery via middle fossa craniotomy in patients harboring tumors with unfavorable characteristics are significantly lower than for those patients with "favorable" tumors. Objectives We will present two cases both with unfavorable conditions, which underwent endoscopic-assisted middle fossa craniotomy (MFC) resection of intracanalicular vestibul...
متن کاملEndoscopic endonasal approach for nonvestibular schwannomas.
BACKGROUND Nonvestibular schwannomas of the skull base often represent a challenge owing to their anatomic location. With improved techniques in endoscopic endonasal skull base surgery, resection of various ventral skull base tumors, including schwannomas, has become possible. OBJECTIVE To assess the outcomes of using endoscopic endonasal approach (EEA) for nonvestibular schwannomas of the sk...
متن کاملAnalysis of hearing preservation and facial nerve function for patients undergoing vestibular schwannoma surgery: the middle cranial fossa approach versus the retrosigmoid approach--personal experience and literature review.
OBJECTIVE To compare hearing preservation and facial nerve function outcomes in patients undergoing vestibular schwannoma surgery performed using either the middle cranial fossa approach (MCFA) or the retrosigmoid approach (RSA). MATERIALS AND METHODS A review of the medical records of patients diagnosed with vestibular schwannoma who underwent surgical tumor removal in a single reference cen...
