Pneumatic dental extractions: an unusual cause of extensive cervical surgical emphysema.

A 50-year-old fit and well man presented to the Accident and Emergency Department in a tertiary centre following lower molar extraction, complaining of voice hoarseness with neck and facial swelling. Clinical examination along with plain film radiography revealed pneumomediastinum and extensive cervical surgical emphysema. He was subsequently admitted for observation and managed conservatively under the ENT team with input from the maxillofacial and anaesthetic teams. With supportive treatment only, the emphysema resolved and he remained well up until discharge. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.
