Introduction: The size of meningioma and its relation with neurovascular structures in petroclival region stipulate the degree of surgical radicalism and determine an operation risk. In spite of progress of surgical technology, the rate of surgical morbidity in view of cranial nerves deficit is 30%-50%. Objective: The objective of our study was to present the results of treatment of patients with petroclival meningiomas and to point to correlation of preoperative radiological findings and intraoperative results as well as neurological status of patients before and after surgical treatment. Method: Retrospective analysis of 35 operated petroclival meningiomas at the Institute of Neurosurgery, CCS, in the period from 1995 to 2004 was presented. The following parameters were analyzed: size of tumor, relation with bone and neurovascular structures, preoperative condition, degree of surgical radicalism and postoperative outcome. Results: The size of tumor was classified in four groups. There were 20 tumors at the right, and 15 at the left side. At the time of diagnostic procedures (based on CT and MRI), 20 tumors were in contact with brainstem, 9 compressed the brainstem, and 6 obstructed the IV ventricle. Preoperative patient condition was evaluated by Karnofsky index. Mean value for group I was 90, II - 80, III - 70 and IV - 50. In 9 cases, liquor drainage was performed preoperatively. In 3 cases, external liquor drainage was carried out postoperatively, and in one case it was replaced by permanent liquor drainage. Radical operation was performed in 44%, and significant reduction was done in other cases. In the postoperative period, 11% patients died, 28% had cranial nerves deficit, and pyramid deficit was recorded in 14% of the patients. The tumor size (III-IV) and brainstem compression were found to be statistically significant (p<0.05) as predisposed factors of deficit prolongation. Conclusion: Petroclival meningoma surgery is reljuired upon precise preoperative analysis. Radicalism of operation is reserved for small and medium tumors, younger patients, and patients in good preoperative condition.

Object Petroclival meningiomas are notoriously difficult lesions to manage surgically, given the critical neurovascular structures that are intimately associated with the tumors. In this paper, the authors' aim was to review their series of patients with petroclival meningiomas who underwent surgical treatment; emphasis was placed on evaluating modes of presentation, postoperative neurological outcome, complications, and recurrence rates. Methods Fifty patients underwent surgical treatment for petroclival meningiomas. The majority of the patients were women (72%). The authors retrospectively reviewed the patients' medical records, imaging studies, and pathology reports to analyze presentation, surgical approach, neurological outcomes, complications, and recurrence rates. Results Headache was the most common presentation (58%). The most commonly used approach was the transpetrous approach (in 16 patients), followed by the orbitozygomatic approach (in 13). Gross-total resection was performed in 14 patients (28%), and in the remaining patients there was residual tumor (72%). Eighteen patients with tumor remnants were treated with Gamma Knife surgery. New postoperative cranial neuropathies were noted in 22 patients (44%). The most common cranial nerve (CN) deficit following surgery was CN III dysfunction (in 11 patients) and facial weakness (in 10). In 9 patients, the CN dysfunction was transient (41%), and 7 patients had permanent dysfunction (32%). Eight patients developed hydrocephalus and all required placement of a ventriculoperitoneal shunt. A CSF leak was noted in only 2 patients (4%), and wound dehiscence was noted in 1. The CSF leaks and the wound dehiscence occurred in patients who were undergoing reoperations. Adequate radiographic follow-up (minimum 6 months) was available for 31 patients (62%). The mean follow-up was 22.1 months. In 6 patients, tumor progression or recurrences were noted. The median time to recurrence was 84 months. At the time of discharge from the hospital, 92% of the patients had good outcomes (Glasgow Outcome Scale Scores 4 and 5). Three patients died of causes not directly related to the surgery. Conclusions Petroclival meningiomas still pose a formidable challenge to neurosurgeons. In their series, the authors used multiple skull base approaches and careful microneurosurgical technique to achieve a good functional outcome (Glasgow Otcome Scale Score 4 or 5) in 92% of patients, although the extent of gross-total resection was only 28%. The authors' primary surgical goal was to achieve maximal tumor resection while maintaining or improving neurological function. The authors favor the treatment of residual tumor or recurrent tumor with stereotactic radiosurgery.
