Introduction: The knowledge of the anatomy surrounding Bichat's fat pad, as well as its clinical applications, is essential to indicate and to safely perform its removal. This surgery is indicated not only for esthetic purposes, but also for functional reasons. When used properly, Bichat's fat pad is composed of stem cells that have a similar phenotype to adipose stem cells, useful in the treatment of pathologies and/or complications, such as maxillary sinus membrane perforation, oroantral/oronasal communications, peri-implantitis, ulcers, fibrosis of the oral mucosa, soft tissue reconstruction, among others. Due to its location, it is prone to suffer clinically significant pathologies, as well as constant trauma. Aim: The aim of this study is to report two clinical cases and subsequent follow-ups, where bichectomy was performed to avoid dental trauma to mucosal tissues during the masticatory function. Also, literature review on the application of Bichat's fat pad in dentistry is provided. Case report: Two female patients (20 and 24 years) reported discomfort and constant pain in the oral mucosa caused by dental trauma. At the clinical examination, patient presented augmented and injured mucosa. The surgical sequence of Bichat's fat pad removal, as well as the extra-/intraoral photographic follow-up (8, 15, 30, and 180 days) of the patients is described. Conclusion: In order to indicate and/or accomplish surgical procedures involving Bichat's fat pad, it is fundamental to know its anatomy and possible applications, not only for esthetic purposes, but also for functional purposes. The patients showed evident improvements following the removal of Bichat's fat pad. Clinical significance: Application of Bichat's fat and its removal should be evaluated, being an alternative in patients who constantly undergo mucosal injury during masticatory function.
