Abstract
Objective: To report the case of extensive traumatic self-bite traumatic tissue loss of the lip after blockage of the lower alveolar nerve for included lower third molar extraction. Case Details: A 20-year-old female patient, leukoderma, without systemic and psychological changes, attended the clinic for extraction of the included dental element 48. The patient underwent uneventful pterigomandibular anesthesia. After the procedure, the patient went home with her anesthetized lip and ended up sleeping. When she woke up, she noticed that she had her face and blood blouse, and when she looked in the mirror, she noticed that she had lost part of her lower lip and that she probably would have chewed and swallowed since she was still under anesthesia. The patient sought the service of the Hospital where she underwent a surgical procedure by the oral and maxillofacial surgery team and plastic surgery under general anesthesia. Final considerations: The surgeon's explanation of postoperative surgeries, local anesthetic care, the duration of drug duration and the effects it may cause pending complete metabolization of the solution in question is of paramount importance.
