The short-term outcomes of surgical scars in head and neck surgery comparing between surgical blade and geometric electron modulation electrocautery.

Background: Scar formation after neck surgery is a frequent concern, impacting patients both physically and psychologically. Cosmetic appearance plays a crucial role in assessing surgical success. At present, the evolving medical technologies introduces innovations like Geometric Electron Modulation (GEM) electrocautery.

Variation of the Great Auricular Nerve and Prediction of the Facial Nerve Trunk Size.

Background: This study aimed to reveal the anatomical variation in the great auricular nerve (GAN) and the correlation between the size of the GAN and the facial nerve trunk (FNT), so as to aid surgeons to perform safe facelift surgery and parotidectomy.

Methods: Sixteen human cadavers were studied on 16 left and 15 right facial sides. The GAN's branching patterns, location, and the mean width of the GAN and FNT were measured.
