Lingually Displaced Third Molar Root during Surgical Removal – A Case Report

NA Jalil, F Maarof, FQ Chao: Lingually Displaced Third Molar Root during Surgical Removal – A Case Report. Mal. J. Oral Maxillofac. Surg. 2015; 13: 34–37.

Abstract: Background: Displacement of tooth into the lingual space is a rare complication of surgical removal of third molars. Once displaced, its retrieval is often difficult due to poor visualization and limited access.

Case Presentation: This case report is of a lingually displaced third molar seen in Oral & Maxillofacial Surgery (OMFS) Department of Queen Elizabeth Hospital, Kota Kinabalu, Sabah. A 24 years old female patient who attended the OMFS department had her 48 removed by a first year dental officer in the department. During removal, the root of her 48 was accidentally displaced into the lingual space. With the aid of an orthopantomogram (OPG), the fragment was later removed by the consultant oral & maxillofacial surgeon using blunt dissection and manual palpation.

Conclusion: Iatrogenic lingual displacement of lower third molar root during surgical removal is a rare but complex complication. Appropriate imaging, good preoperative evaluation and competent instrumentation and techniques may reduce the incidence of iatrogenic displacement of tooth during surgical removal.
