Endoscope-assisted surgical resection of acoustic neuroma / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To explore the therapeutic efficacy and complications of endoscope-assisted surgical resection of acoustic neuroma.@*METHOD@#Assisted by hard-tube ear endoscope, 11 patients with acoustic neuroma were operated via labyrinthine approach and retrosigmoid approach.@*RESULT@#Total removal was achieved in 9 (81.8%) cases, while subtotal removal was achieved in 2 (18.2%) cases. Facial nerves and cochlear nerves were preserved completely during operation in all cases. After operation 9 (81.8%) cases had no facial paralysis, while the other 2 cases (18.2%) had mild peripheral facial paralysis. The same hearing level as that of preoperation in 2 patients (18.2%), hearing impairment in different degrees in 9 patients (81.8%), among which moderate sensorineural hearing loss in 1 patient, moderate to severe in 2 patients, severe in 3 patients, profound in 3 patients.@*CONCLUSION@#The application of ear endoscope in acoustic neuroma surgery can improve the total removal rate of tumors and the salvage rate of vessels and nerves. However, its disadvantages make it an assistant method for microsurgery.
