Life-Threatening Hemorrhage from the Lingual Artery after a Genioplasty-Case Report and Review of Possible Complications Associated with Orthognathic Surgeries

Life-threatening hemorrhage after orthognathic surgery is rare. However, when it occurs, immediate diagnosis of the source of bleeding is imperative for successful management. The current report is the first to describe a rare life-threatening bleed from the left lingual artery following a genioplasty in a young healthy patient. Such occurrence also emphasizes the diverse anatomical course of the lingual artery and focuses on raising awareness about its numerous variations, sites of origin. Surgeons are often unaware of the anatomic variations of the lingual artery and its relation to the surrounding structures, which often lead to unexpected hemorrhages. Moreover, depending on severity, they can become challenging to manage and may lead to life-threatening complications. Taking into consideration the variations and the classification of the anatomical course of the lingual artery will improve surgical outcome, reduce morbidity, and lead to appropriate healing and recovery. This previously unpublished case regarding complications of lingual artery hemorrhage after genioplasty can bring awareness for future surgical considerations.
