<p>Mini-implants for orthodontic anchorage are commonly used for orthodontic treatment. Inflammation of periodontal ligaments, root damage, fractures, and loss of fixation have been reported as complications associated with mini-implants. Nevertheless, emphysema has not yet been reported. We report a case of emphysema caused by nose blowing after removal of mini-implants.</p><p>　A 43-year-old woman was referred to our hospital because of swelling of her right cheek. One day before, two mini-implants had been placed in her right maxillary molar region at another hospital. However, they were removed because of inadequate anchorage. Swelling of her right cheek suddenly occurred after nose blowing. Computed tomographic images revealed perforation of the right maxillary sinus and pneumatic spaces around the right eyeball, in the subcutaneous tissue of the right eyelid, as well as in the temporal, buccal, and cervical regions. The diagnosis was subcutaneous emphysema in the right side of the face and neck. The patient was given antibiotics for 1 week, and the symptoms of emphysema resolved. To prevent emphysema after the placement of mini-implants in the maxillary molar region, it is necessary to perform thorough preoperative examinations and to appropriately explain postoperative self-care to the patient.</p>
