Surgical correction of sunken upper eyelid with upper arcus marginalis release and precision fat distribution technique.

Background: Sunken upper eyelids, characterized by hollowing in the upper orbital region, can contribute to an aged or fatigued appearance. We aim to report on the surgical technique and its effects, involving the release of the arcus marginalis of the upper eyelid and the precise distribution of orbital fat.

Methods: From December 2021 to March 2023, a total of 84 eyelids from 42 patients who underwent surgical correction for sunken upper eyelids, utilizing the upper arcus marginalis release and precision fat distribution technique, were included in this study.

Sliced Costochondral Chip Grafts in Posttraumatic Enophthalmos Correction.

Background: Posttraumatic enophthalmos is a relatively common problem following orbitozygomatic fractures. However, inadequate long-term results are frequently observed due to the difficulty of performing intraoperative fine adjustments to soft-tissue volume and orbital size and gradual absorption of some grafted materials. Here, the authors describe an efficient method of enophthalmos correction using sliced costochondral bone and cartilage combination grafts.

Experimental Forelimb Allotransplantation in Canine Model.

As reconstructive transplantation is gaining popularity as a viable alternative for upper limb amputees, it is becoming increasingly important for plastic surgeons to renew surgical skills and knowledge of this area. Forelimb allotransplantation research has been performed previously in rodent and swine models. However, preclinical canine forelimb allotransplantation studies are lacking in the literature.
