We examined the surgical anatomy of the ophthalmic artery (OA) by dissection of cadaver heads, evaluating the anatomic relationships between the origin of the OA and both its proximal course and surrounding structures. In addition, we demonstrated the surgical application of these anatomic features for safe surgical exploration of this region. ⋯ Our anatomic findings demonstrate anatomic variation of the OA in terms of its region of origin. Several anatomic points that were noteworthy during surgical exploration of this region are discussed.

We have developed scaled suction to facilitate the measurement of aneurysm neck width and tumor size during operations. ⋯ Our scaled suction device is a simple and useful navigator for continuously measuring intraoperative variables such as lesion size and distance between the lesion and the surrounding vital structures.

The mini-open approach for transforaminal lumbar interbody fusion is described in detail. Operating room setup and surgical positioning are demonstrated. ⋯ The surgical technique used for decompression and fusion is presented in detail. The surgical pearls and pitfalls of the mini-open TLIF are described and illustrated.
