In clinical oral surgery, we often encounter cases of infants who fall down while holding a toothbrush in their mouth and receive an oral injury from a toothbrush. This particular case was that of a 5-year-old girl who accidentally injured her left buccal mucosa with a toothbrush. After the injury, she was immediately brought to the hospital by ambulance. When she arrived at our hospital, the toothbrush was still embedded in the oral wound. We examined her oral wound by computer tomography (CT). We found that the tip of the toothbrush was located in the vicinity of the left medial pterygoid muscle, and there was neither damage from the toothbrush itself nor on the maxillary artery and basal skull. We removed the toothbrush carefully under local anesthesia, and then cleaned the wound by adequate normal saline and administered antibacterial drugs (SBT/ABPC) intravenously. No serious complications were seen after the treatment.It is strongly suggested that in such a case an immediate examination be conducted by CT in order to avoid severe complications and to insure a good healing process.

Malignant tumors rarely arise from jaws cyst. We report a case of squamous cell carcinoma arising from a nasopalatine duct cyst. A 70-year-old man presented with a swelling in the palatal gingiva at the middle of the maxilla. Oral examination showed a 28×25mm swelling with a puncture mark, asmooth surface, and normal color. Radiographic examination revealed a round translucent image measuring 15×12mm in diameter in the middle of maxilla. The image was clearly demarcated. Under general anesthesia, extirpation of the cyst was performed for a diagnosis of nasopalatine canal cyst. Histopathological examination of the resected specimens showed transition of histologically normal cystic epithelium to squamous cell carcinoma. After the first operation, partial resection of the maxilla was performed. Three months after the partial resection, left jugular lymph node metastasis was detected. Partial neck dissection, chemotherapy, and irradiation were performed. Twelve months after partial resection of the maxilla, right jugular lymph node metastasis was found. Radical neck dissection was performed.For 2 years 4 months, there was no disease recurrence. However, the patient died due of pneumonia on April 13, 2002.
