Summary
Retrosigmoid cranial nerve surgery for hemifacial spasm, trigeminal neuralgia, and glossopharyngeal neuralgia is generally safe. However, severe complications like hearing loss and cerebrospinal fluid leakage can occur, necessitating careful surgical attention.
Area of Science:
- Neurosurgery
- Cranial Nerve Surgery
- Retrosigmoid Approach
Background:
- The retrosigmoid approach is utilized for treating hemifacial spasm (HFS), trigeminal neuralgia (TN), and glossopharyngeal neuralgia (GPN).
- Procedures include microvascular decompression (MVD), facial nerve splitting (FNS), and neurectomy.
Observation:
- A review of 516 cases undergoing retrosigmoid cranial nerve surgery was conducted.
- The study analyzed complications associated with MVD, FNS, and neurectomy for HFS, TN, and GPN.
Findings:
- Two fatalities (0.4%) occurred. Hearing impairment affected 6.0% of patients, with 0.8% experiencing total hearing loss.
- Postoperative cerebrospinal fluid leakage was observed in 5.6% of cases.
Implications:
- While generally safe, retrosigmoid cranial nerve surgery carries risks of severe complications.
- Meticulous surgical technique is crucial to minimize adverse outcomes in patients undergoing these procedures.
