[Meningitis in otologic surgery of acoustic neurinoma]
Abstract:
Bacterial meningitis following operation for ablation of acoustic neurinoma is a rare but always possible complication. Of 350 cases of neurinoma operated upon between 1965 and 1982, this postoperative lesion was reported in eleven patients (3.4 p. 100). Recovery occurred in all cases without sequelae. Mode of onset, symptoms and signs, curative therapy and preventive factors are discussed.
Insights
Bacterial meningitis can occur after acoustic neurinoma surgery, affecting 3.4% of patients in one study. Fortunately, all patients recovered fully without lasting effects.
Area of Science:
- Neurosurgery
- Infectious Diseases
- Neurology
Background:
- Acoustic neurinoma (vestibular schwannoma) is a tumor arising from the nerve sheath of the cranial nerve VIII.
- Surgical ablation is a primary treatment for acoustic neurinoma.
- Postoperative complications, including infection, are a concern following neurosurgery.
Observation:
- A retrospective review of 350 patients who underwent acoustic neurinoma ablation between 1965 and 1982 was conducted.
- Eleven patients (3.4%) developed bacterial meningitis as a postoperative complication.
- The study analyzed the onset, clinical presentation, treatment, and prevention of this complication.
Findings:
- Bacterial meningitis is a rare but documented complication following acoustic neurinoma surgery.
- The incidence observed was 3.4% in the studied cohort.
- All affected patients achieved complete recovery without any long-term neurological deficits.
Implications:
- Awareness of this potential complication is crucial for neurosurgical teams.
- Prompt diagnosis and appropriate antibiotic therapy are key to successful outcomes.
- Further research into preventive strategies may reduce the incidence of postoperative meningitis.
