RESUMO
Subcutaneous emphysema occurs when air is forced under the tissue, causing swelling, crepitus on palpation, and the possibility of spreading along the fascial planes. Although subcutaneous emphysema secondary to dental procedures is rare, it can be a potentially fatal complication if not diagnosed and treated promptly and correctly. Dentists need to be able to differentiate subcutaneous emphysemas from more common disease processes that have similar clinical presentations. We report a 22-year-old male who underwent mandibular wisdom tooth extraction and subsequently developed extensive subcutaneous emphysema. The patient was quickly taken care of, in partnership with the maxillofacial department. The purpose of this report is to bring attention to the fact that obtaining an accurate diagnosis for this condition is very important and management on time can prevent serious complications.
