Object The goals of this study were twofold: 1) to determine outcome, including quality of life, in patients who have undergone surgery for petroclival meningioma in which a standard skull base approach was used; and 2) to assess the impact of the patients' surgical treatment on their caregivers. Methods Seventeen patients (13 women and four men ranging in age from 29 to 63 years) who underwent a transpetrosal approach for a petroclival meningioma during a 5-year period were prospectively included in this study. Pre- and postoperative data including adverse events were noted. The patients were assessed at 3, 6, and 12 months postoperatively, and annually thereafter, and they completed a postoperative SF-36 questionnaire. In addition, each patient's caregiver was interviewed to determine the effect of the patient's illness on the caregiver's life and responsibilities. Twenty-two operations were performed. A new permanent neurological deficit developed in five patients and in eight a temporary deficit or exacerbation of existing deficits occurred. Two patients underwent surgery to create a facial-hypoglossal nerve communication; five required a temporary percutaneous gastrostomy and/or tracheostomy; three required a shunt; and one underwent successful squint surgery. At 1 year postoperatively 13 patients had made a good or moderate recovery, three were severely disabled, and one had died--outcomes in keeping with other studies. By contrast, responses to the SF-36 questionnaire showed that, in all eight of its categories, between 43% and 75% of surviving patients were functioning below accepted norms. Fifty-six percent of caregivers experienced a major change in lifestyle and 38% experienced a major change with respect to their work. Conclusions After transpetrosal excision of a petroclival meningioma, the quality of life for the patient is worse than that indicated in surgeons' reported results. The impact on the patient's caregiver is profound--a burden perhaps not fully appreciated by the surgeon.

Abstract The pons is the most frequent local for brain stem cavernoma.1 Repeated hemorrhage of brainstem cavernoma is associated with significant and accumulative neurological deficits and thus requires treatment. According to the Swedish Karolinska’s group of radiosurgery, ”it could not be concluded whether GKRS affects the natural course of a CM. The incidence of radiation-induced complications was approximately seven times higher than that expected.”2 Thus, microsurgical removal has become the mainstay of treatment. In our experience, the following details assist in obtaining favorable outcomes and avoiding postoperative complications3,4: (a) the entry into the cavernoma based on thorough knowledge of the microanatomy; (b) the detailed study of the images and the presentation of the cavernoma on or near the brain stem surface; (c) the resection of the live cavernous hemangioma and not the mere removal of the multiple aged organized hematomas; (d) the preservation of the associated venous angioma; (e) the direct and shortest access to the lesion provided by a skull base approach; and (f) the use of the available technology, such as intraoperative neuromonitoring and neuroimaging. We present the case of a 54-yr-old male with recent deterioration in year 2001, past repetitive episodes of gait imbalance, and speech difficulty over a 7-yr period from known pontine cavernoma. The anterior petrosal approach provided superb and direct exposure to the entry at the lateral pons and the cavernoma was totally removed with preservation of the venous angioma. His preoperative neurological deficit rapidly recovered. Patient consented to the procedure and photography.

Abstract Objective: We examined the surgical approaches used at a single institution to treat petroclival meningioma and evaluated changes in method utilization over time. Methods: Craniotomies performed to treat petroclival meningioma between September of 1994 and July of 2005 were examined retrospectively. We reviewed 46 patients (mean follow-up, 3.6 yr). Techniques included combined petrosal or transcochlear approaches (15% of patients), retrosigmoid craniotomies with or without some degree of petrosectomy (59% of patients), orbitozygomatic craniotomies (7% of patients), and combined orbitozygomatic-retrosigmoid approaches (19% of patients). In 18 patients, the tumor extended supratentorially. Overall, the rate of gross total resection was 43%. Seven patients demonstrated progression over a mean of 5.9 years. No patients died. At 36 months, the progression-free survival rate for patients treated without petrosal approaches was 96%. Of 14 patients treated with stereotactic radiosurgery, none developed progression. Conclusion: Over the study period, a diminishing proportion of patients with petroclival meningioma were treated using petrosal approaches. Utilization of the orbitozygomatic and retrosigmoid approaches alone or in combination provided a viable alternative to petrosal approaches for treatment of petroclival meningioma. Regardless of approach, progression-free survival rates were excellent over short-term follow-up period.
