Function-preserving intracapsular enucleation of brachial plexus schwannomas: Is it safe and effective?

Brachial plexus schwannomas are rare diseases treated by complete resection, leading to potential neurological deficits. Intracapsular enucleation is an acceptable alternative to preserve the involved nerve function. This study has examined the safety and effectiveness of intracapsular enucleation in preserving nerve function. This observational study included 19 consecutive patients with brachial plexus schwannomas originating from the roots (42 %), the trunks (37 %), and the cords (21 %). After enucleation, immediate sensory and motor weakness occurred in 21 % and 11 % of patients, and other early complications did not happen. No patients had neural deficits at postoperative one year and recurrence for a median follow-up of 72 months. In conclusion, function-preserving intracapsular enucleation via a lateral collar incision is a safe and effective treatment for brachial plexus schwannomas.
