Postanaesthetic Aseptic Palatal Necrosis - A Case Report

RATIONALE: In dentistry, the most common procedure to be applied is administration of a local anaesthetic agent. It is impossible to practice dentistry without local anaesthesia. In the oral cavity, the palatal mucosa is tightly adherent to the palatal bone and there is little space for anaesthetic solution to be deposited. If local anaesthetic is forcefully injected by the syringe, it creates pressure on blood vessels and causes palatal necrosis. PATIENT CONCERN: Here, we present a case report of a 25-year-old male patient who reported to us with chief complaint of an ulcer on the palate. DIAGNOSIS: Patient was diagnosed with postanaesthetic aseptic palatal necrosis. INTERVENTION: The patient was managed conservatively using copious irrigation and a palatal acrylic splint. OUTCOME: On the 6(th) month follow-up, the lesion was completely replaced by healthy mucosa. TAKE-AWAY LESSONS: We should avoid forceful injection of local anaesthetic agent to prevent further postoperative complications.
