Supraorbital keyhole approach for microsurgical treatment of aneurysms in the anterior circulation / 中华外科杂志

<p><b>OBJECTIVE</b>To study the method with endoscope-assisted microsurgical technique through the supraorbital keyhole approach to treat aneurysms in the anterior circulation.</p><p><b>METHODS</b>According to preoperative diagnostic imagings, to work out of the individual operation planning. Skin incision was made in the eyebrow, and the diameter of supraorbital craniotomy was about 2 cm, endoscope-assisted microsurgical technique was used to clip aneurysm. The technique was used in the most recent 12 consecutive patients.</p><p><b>RESULTS</b>Five different kinds of aneurysms in the anterior circulation were clipped through this method and 12 patients were cured. One patient, intraoperative accidental aneurysm rupture occurred. There were no approach-related complications.</p><p><b>CONCLUSIONS</b>This endoscope-assisted microsurgical technique via supraorbital keyhole approach is a safe, minimal invasive and effective way for the treatment of aneurysms in the anterior circulation, and there is more sufficient operating space.</p>

Endoscope-assisted supraorbital keyhole approach for excision of suprasellar region tumor / 中华外科杂志

<p><b>OBJECTIVE</b>To study endoscope-assisted microsurgical technique with supraorbital keyhole approach for the treatment of suprasellar region tumor so as to maximize tumor removal and minimize operative-trauma.</p><p><b>METHODS</b>According to high resolution CT and MR images before operation, individual operation schemes were worked out. Skin incision was made in the eyebrow, and the diameter of supraorbital craniotomy was approximately 2 cm. Endoscope-assisted microsurgical technique was used to resect lesions in 16 consecutive patients.</p><p><b>RESULTS</b>Total Tumors were removed in all of the 16 patients via the supraorbital keyhole approach. No postoperative complications occurred.</p><p><b>CONCLUSIONS</b>Supraorbital keyhole approach may diminish tissue injury considerably and has proven to provide sufficient operating space in the suprasellar region for tumor removal.</p>
