Extensive subcutaneous emphysema, pneumomediastinum, and pneumorrhachis following third molar surgery.

Third molar extraction is a common procedure in dental surgery. Common complications that may occur post procedure include pain, trismus, bleeding, dry socket, and nerve injuries. Subcutaneous emphysema is an uncommon complication. A rare case of extensive cervicofacial subcutaneous emphysema, pneumomediastinum, and pneumorrhachis following third molar extraction is reported here. Issues relating to the diagnosis, aetiology, and management of these complications are discussed.
