Methods: This study was retrospectively conducted on twenty four patients, age ranging from 20 to 65 years old, with anterior cranial fossa lesions who were meeting the eligibility criteria for eyebrow craniotomy in the period from August 2019 to January 2023. These patients were operated through eyebrow supraorbital approach in which microscopic endoscopic assisted technique were used. Extent of resection, clinical and cosmetic outcomes and complication incidence were assessed. Results: We included the twenty four patients who met inclusion criteria (17 females and 7 males) their ages ranged from 20 to 65 years. The most common pathology was meningioma in 19 patients. Two patients experienced supraorbital loss of sensation and only one patient experienced palsy of frontalis branch of facial nerve. Frontal sinus was breached in 3 patients with no patient experienced postoperative CSF leak. Total excision was accomplished for 23 patients. Four patients who had preoperative visual compromise, improvement of visual acuity and field defects was observed in 3 patients. No major intraoperative complications occurred. All patients filled cosmetic satisfaction questionnaire during their outpatient visits. For the eyebrow supraorbital approach, no incision related intolerable pain, no craniotomy defects or irregularities, no cosmetic complaints nor limitation of jaw opening were reported, and only minor symptoms in the form of limited eyebrow elevation, swelling and numbness in the forehead. Conclusions: The eyebrow craniotomy could be used safely as a more cosmetic and minimally invasive approach for a variety of anterior cranial fossa lesions. Endoscopic assistance has been found very useful for deeply seated lesions and hidden residuals with minimal brain retraction which couldn’t be accessed easily through microscopic field solely. Endoscopic assisted eyebrow supraorbital keyhole approach could be performed on a wider scale with great results but requires good selection of cases and more practice to expertise the needed skills.展开更多

This report summarized our experience in 25 patients with petroclival meningioma who had been treated with keyhole approach surgery. Methods From July 2000 to July 2005, 25 patients with petroclival meningioma were subjected to resection via subtemporal, retrosigmoid or combined keyhole approaches. The extent of tumor resection was evaluated by MRI 3 months after surgery, and postoperative complications were investigated. Results The maximum diameter of tumors ranged from 2 to 7 cm （mean, 4.5 cm）. Gross total resection （GTR） was achieved in 14 patients, giving a GTR rate of 56%. Subtotal resection （STR） was carried out in 8 patients and partial resection in 3. Thirteen patients kept normal neurological status, whereas others suffered from cranial nerve deficits （Ⅶ, Ⅶ, Ⅲ and lower CN）. One patient died in the postoperative period. Conclusions Keyhole approach surgery, especially the combined keyhole approach is suitable for the treatment of petroclival meningioma. It provides easy and quick access to the supra- and infratentorial juxta-clival region without drilling of the petrous bone. Complications related to the approach can be minimized.展开更多
