Overview
The feasibility of surgery depends on the stage of schwannoma at diagnosis. Surgery is the mainstay of treatment for schwannoma. There are three main approaches like translybyrinthine, retrosigmoid, middle fossa. The common complications of surgery include vertigo, hearing loss is another important complication associated with the operation, post-operative headache, cerebrospinal fluid (CSF) leakage, facial paralysis
Indications
- Surgical intervention is recommended the management of schwannoma.
Surgery
- The feasibility of surgery depends on the stage of schwannoma at diagnosis.
- Surgery is the mainstay of treatment for schwannoma.
- The following table compares the different type of surgical approaches for vestibular schwannoma management.
| Translybyrinthine | Retrosigmoid | Middle fossa | |
|---|---|---|---|
| Indications | Non-serviceable hearing; any IAC or CPA VS | VS with large CPA component; medial IAC VS | Small lateral IAC VS (<0.5 cm); small medial IAC VS with < 1 cm CPA component |
| Advantages | Minimal brain retraction | Panoramic CPA exposure; better facial nerve and hearing preservation for medial VS | Better exposure lateral IAC |
| Disadvantages | Complete hearing loss; difficult approach for CPA VS ventral to porus acusticus; risk for facial nerve injury | Limited access to lateral IAC; potential for cerebellar and brainstem injury | Limited PF access; temporal lobe retraction; risk for facial nerve injury |
- The common complications of surgery include the following:
- Vertigo
- Hearing loss
- Post-operative headache
- Cerebrospinal fluid (CSF) leakage
- Facial paralysis
Contraindications
