Iatrogenic Cervicofacial Emphysema and Pneumomediastinum after Wisdom Tooth Extraction

Y. Dennai, F. Slimani

Abstract: Subcutaneous emphysema and pneumomediastinum following extraction of mandibular third molars are rare. These complications are caused by air forced into the loose connective tissue under the dermal layer at the site of extraction while using a high-speed air-turbine dental drill. The symptoms may vary depending on the quantity of air, its location and the presence or absence of infection. In most cases, the subcutaneous emphysema will begin to disappear in 3-5 days. This report presents a case of subcutaneous emphysema and pneumomediastinum after wisdom extraction.
