상악 제3대구치 발거후 발생한 광범위한 피하기종 = SUBCUTANEOUS EMPHYSEMA FOLLOWING EXTRACTION OF MAXILLARY THIRD MOLAR

다국어 초록 (Multilingual Abstract)

Subcutaneous air emphysema is a relatively uncommon phenomenon. It has been reported in both the medical and dental literature following such various procedures as rectal biopsy, nasogastric intubation, radical neck dissection, tonsillectomy, adenoidectomy, root canal treatment, dental restoration and extraction of maxillary and mandibular teeth. The most common cause involves extraction of mandibular third molar.
Subcutaneous emphysema of the head, neck and thorax is a swelling caused by introduction of air into the space of the connective tissue.
The clinical signs are local swelling, tenting of the skin, and crepitation on palpation.
In extreme casesk, air has been reported to pass through the masticatory space into the parapharyngeal and retropharyngeal space, and penetrate into the mediastinum. If the inflowing air contains bacteria, serious infection may ensue.
The first case of subcutaneous emphysema associated with a dental procedure was first reported in 1900. This emphysema is a often limited only to the spaces of head and neck, but also can involve deeper structure.
This case is diffuse subcutaneous emphysema following maxillary third molar extraction with a high-speed drill.
