Vascular anatomy of anterolateral thigh flap.

Objectives: To understand the vascular anatomy of the anterolateral thigh (ALT) free flap. To anatomically determine whether including a 2-cm cuff of vastus lateralis muscle (VLM) incorporates musculocutaneous perforators in the harvest of the ALT free flap.

Study Design: Anatomic study on human cadavers.

The voice-controlled robotic assist scope holder AESOP for the endoscopic approach to the sella.

Objective: To evaluate the feasibility of using a voice-controlled robot Automated Endoscopic System for Optimal Positioning (AESOP) for holding and maneuvering the endoscope in the trans-sphenoidal approach to the pituitary.

Design: To compare the manual approach to the voice-activated robotic scope holder in maneuvering the endoscope and resecting pituitary lesions using a two-handed technique.

Setting: Robotic laboratory at Louisiana State University Health Sciences Center, Shreveport.
