Transient alopecia and transient facial nerve palsy following scalp autologous fat grafting: a case report of an unusual complication

Facial fat grafting is a common procedure in plastic, aesthetic and maxillofacial surgery. Indications are facial rejuvenation, lip augmentation, correction of asymmetries or facial soft tissue volume defects and softening of scar tissue. Complications reported are scarce and usually temporary. Common side effects are bruising, swelling, feeling of numbness or altered sensation of the injected area. Uncommon complications such as bleeding and infection have been described. Transient hair loss at the fat-injected site is rarely reported as a complication of. of facial autologous fat grafting. We report a case of transient scalp alopecia following fat grafting of the temporal area in a reconstructive context. The aim of this case report is to make surgeons aware of this possible complication and its management as well as expose its differential diagnosis.
