Abstract

Objective: Sporadic acoustic neuroma, usually occur between the ages of 40 and 70 years, are very rare in children. We review the experiences of 10 cases of sporadic (non-NF2) acoustic neuromas in pediatric patients. Method: During last 26 years 2000 skull base procedures were performed in the Otorhinolaryngology Unit of the Ospedali Riuniti di Bergamo. Among these almost 900 cases were acoustic neuromas. Only 10 were at or under the age of 18 years. Results: The age of the youngest patient in our series was 12 years. Deafness were the commonest presentation and were seen in eight patients. It varied between 10 and 65 dB sensorineural hearing loss. Among these eight cases, two patients have sudden onset of hearing loss. Two patients presented with dizziness. The duration of complaints were between 2 months and 5 years in these patients. The diameter of the tumors varied widely with minimum of 10 mm to maximum up to 60 mm. Five patients each underwent resection of the tumor by translabyrinthine and retrosigmoid approach, respectively. The minimum postoperative follow-up was 3 years and maximum was 22 years in our series. Postoperatively seven cases the facial nerve recovered to grade I, and one each to grade II and grade VI of House-Brackmann classification. All five cases who underwent retrosigmoid approach had moderate (40 dB) to total sensorineural hearing loss postoperatively. The youngest patient with largest tumor diameter of 60 mm developed transient hemiparesis in the immediate postoperative period and he recovered fully in due course. Conclusion: We found preservation of facial nerve function is more easier than hearing in this group of patients.
