Abstract

Objectives: The purpose of this study was to evaluate the clinical features and surgical outcome of CP tumors with retractorless method.
Material and Methods: It is a retrospective study of 7 cases operated in Neurosurgery Unit 1, PINS/Lahore General Hospital, Lahore. Study span was 2 months and follow up duration was 15 days. Predominating symptoms were related to cranial nerves 5th, 6th, 7th, 8th and cerebellum.
Results: Age range was 25 – 45 years with an average age of 35 years. 4 patients were male and 3 patients were female. In all patients, surgery was performed. Clinical presentation was tinnitus, decrease hearing, hearing loss, abnormal balance, headache, facial numbness, buccal numbness, ataxia and trigeminal neuralgia in one case. All patients were operated through retrosigmoid sub-occipital approach with retractorless method. VP shunt was inserted in 3 cases and EVD was done in all other cases just before surgery. Histopathology report was 4 patients were of vestibular schwannoma, 2 were of meningioma and 1 was of epidermoid cyst. Five patients operated successfully with no new focal neurological deficit. One patient died intraoperatively and one patient was re-explored postoperatively due to intracranial hemorrhage.
Conclusion: It is concluded that surgery via the retrosigmoid approach with retractorless method is relatively safe corridor for the treatment of CP Angle Tumors.
