OBJECTIVE: Cholesterol granulomas are benign lesions that sometimes occur on the petrous apex (PA). We report our experience using an endoscopic endonasal approach to remove PA cholesterol granulomas. MATERIAL AND METHODS: A retrospective patient chart analysis was conducted at a tertiary care university hospital. RESULTS: Four patients (3 females, 1 male) were included in this study. Patients' ages ranged from 27 to 78 years. Computed tomography (CT) and magnetic resonance imaging (MRI) for diagnosis and computer-assisted navigation were performed. The most common symptom was abducens nerve palsy. The largest granuloma measured 5 x 2 cm and was located on the left side. An endoscopic endonasal approach was chosen and navigation was applied (3/4 patients) to identify the optimal area for opening the granuloma. No complications occurred, and patients were free from recurrence during the follow-up period. CONCLUSION: The endoscopic endonasal approach to PA cholesterol granulomas is feasible and safe. Intra-operative navigation is recommended to identify the position of the internal carotid artery and determine the safest area for opening the granuloma without damaging the artery. Another advantage of this approach is an easier follow-up through diagnostic nasal endoscopy.

OBJECTIVE: To date, the efficacy and safety of repeat radiosurgery (RS) for trigeminal neuralgia (TN) is based mainly on short term results. METHODS: Between 1994 and 2006, 93 patients were treated by RS for TN at the Department of Neurosurgery, Graz, Austria. 22 patients underwent repeat gamma knife radiosurgery (GKRS) a mean of 18.8 months after the initial treatment. The mean dose for repeat treatment was 74.3 Gy. Pain outcome was rated using the Barrow Neurological Institute (BNI) Pain Intensity Scale and facial numbness according to the BNI Facial Numbness Scale. RESULTS: Mean follow-up after repeat RS was 5.4 years. Pain relief was noted in 72.7% (16/22) of patients; six patients had a second pain recurrence after a mean of 9.3 months and underwent medical, alternative and/or further RS. One patient was lost to follow-up. BNI pain scale evaluation for 21 patients indicated improvement in 76.2% (16/21) of cases without medication (BNI I and II). Facial numbness was recorded in 73.7% (14/19) but in only one was it classified as bothersome. CONCLUSIONS: Long term observation of repeat GKRS for TN showed good pain relief in more than two-thirds of patients. Despite a high percentage of facial numbness, most likely attributable to the higher delivered dose, repeat RS can still be regarded as safe. However, further studies are needed to determine an optimised treatment protocol.
