Summary
This study reports on 47 acoustic neurinoma surgeries, noting a rise in prevalence. Surgical outcomes show high facial nerve preservation rates and low complications, indicating effective treatment for these tumors.
Area of Science:
- Neurosurgery
- Otolaryngology
- Neurology
Background:
- Acoustic neurinomas, benign tumors of the vestibulocochlear nerve, present a surgical challenge.
- The period 1987-1989 saw a notable increase in acoustic neurinoma diagnoses and surgical interventions.
Purpose of the Study:
- To evaluate the surgical outcomes and complication rates for acoustic neurinoma resection.
- To assess the preservation of facial nerve function and hearing following surgery.
Main Methods:
- Retrospective analysis of 47 acoustic neurinoma surgeries performed on 46 patients between 1987 and 1989.
- Classification of tumors by size (large, medium, small) and assessment of surgical excision completeness.
- Evaluation of postoperative facial nerve function, hearing preservation, and overall complication rates.
Main Results:
- Out of 47 tumors, 26 were large, 18 medium, and 1 small. Complete excision was achieved in 16 cases, incomplete in 31.
- Facial nerve function was preserved in 80% (36/47) of patients, with 60% (27/47) exhibiting good function.
- Postoperative mortality was low (2 patients), and useful hearing was preserved in most cases, with a low overall complication rate.
Conclusions:
- Surgical management of acoustic neurinomas during this period demonstrated favorable outcomes.
- High rates of facial nerve preservation and hearing preservation, coupled with a low complication profile, underscore the efficacy of surgical intervention.
