Abstract:
Objective The aim of this study was to investigate the heating and facial nerve preservation in the middle fossa approach surgery for the removal of small acoustic tumor (vestibular schwannomas,VS).Methods A prospective database was established,and data were retrospectively reviewed.Between January 2004 and February 2013,13 patients with acoustic tumor underwent surgery via middle fossa approach for heating preservation.The patients consisted of six men and seven women with a mean age of 48 years.Tumor size ranged from 0.8 cm to 1.5 cm.Heating loss was categorized as American Academy of Otolaryngology Head and Neck Surgery (AAO-HNS) class A,class B,class C and class D.Facial nerve function was evaluated according to House-Brackmann (HB) Grade Ⅰ-Ⅵ.Results Grosstotal resection was accomplished in 12 of 13 patients.Preoperative heating as class A in ten,class B in two,and class C in one patient respectively.Postoperatively,heating was graded as class A in eight patients,class B in 3,and class C in 2 patients.Facial nerve function was House-Brackmann(HB) grade Ⅰ in twelve patients,grade Ⅱ in one patient preoperatively.Postoperatively,facial nerve function was HB Grade Ⅰ in twelve patients and Grade Ⅲ in one patient.The overall heating preservation rate was at least 80％ (8/10)and HB Grade Ⅰ facial nerve outcome of 100％ (12/12).All cases were followed up for 0.5 to 5 years,no complications were abserved.Conclusions The middle fossa approach for the resection of small VS with heating preservation is a viable and relatively option.It should be considered among the various options available for the management of small and growing VS.
