Most of the intraoral infections origin in odontogenic infection. Odontogenic infection spreads out along the least resistant path. In maxilla, the thickness between periapical area and cortical bone is narrower on the buccal side than the palatal side. So infection usually spreads out along the buccal side rather than the palatal side. The failure of root canal treatment more frequently occurs on the buccal root compared to the palatal root. So the palatal abscess is rarer than the buccal abscess. It is difficult to differential diagnosis palatal abscess from salivary gland tumors, benign neural tumors and cysts on the palate. Therefore, when the palatal swelling is observed in children, you need to prevent the systemic spread of infection by early diagnosis of the odontogenic palatal abscess. In these cases, the patient who complained of the pain in deciduous teeth and the palatal swelling was diagnosed with odontogenic palatal abscess. The patient was treated with extraction and antibiotic medication. The palatal abscess was resolved, and we report after treatments.

Intracranial involvement by adenoid cystic carcinoma (ACC) is very rare and there is no report of intracranial extension from the palate ACC in Korea. Intracranial involvement can occur in one of three ways: direct extension, perineural spread, and hematogenous spread. A case report of a 35-year-old woman with intracranial ACC is presented. Initially she had ACC of the right palate and was treated by surgery and postoperative radiation therapy. Three years and 10 months later, the paresthesia in the distribution of ophthalmic and maxillary branch of right trigeminal none developed without evidence of recurrence in CT scan. Ptosis and total ophthalmoplegia developed sequentially and the second operation was peformed. It was suggested that the tumor was spread perineurally along the trigeminal news into the Gasserian ganglion and then cavernous sinus and orbit. Seven years and 6 months after the first operation, direct intracranial extension into the right temporal lobe developed via sphenoid bone, sphenoid sinus and temporal bone and the third operation was done. And then lung metastasis was diagnosed. She is alive for 9 years 5 months after first operation.

Leiomyoma is benign neoplasm of smooth muscle, but it is rare in the oral cavity. The most common type of leiomyoma in the oral cavity is vascular leiomyoma. Clinically, vascular leiomyoma usually grows slowly and is generally a small, painless, sessile, firm and superficial nodule like lesion, and the length of time before patients seek medical attention may span months to years. The diagnosis of oral leiomyoma is possible with only histological studies with special stains because there are no specific clinical and radiological signs. We experienced a 53-year-old woman with palatal mass. She underwent surgical excision and the final pathological result confirmed it to be vascular leiomyoma. We report this case with a review of the related literatures.

The present study was based on the multicenter study and retrospective method of 200 patients with intraoral minor salivary gland tumors which were received at the Yonsei university dental hospital, Soonchunhyang Bucheon hospital and Yonsei university Severance hospital from 1990 to 2006. In this study, 61.5% of the cases were benign tumor and 38.5% were malignant tumor. Of the benign tumors, pleomorphic adenoma was the most common benign tumor (n=104) and Warthin's tumor, lymphangioma, myoepithelioma and basal cell adenoma were followed. Of the malignant tumors, adenoid cystic carcinoma was the most common malignant tumor (n=32) and mucoepidermoid carcinoma, adenocarcinoma, carcinoma ex pleomorphic adenoma, metastatic adenocarcinoma and acinic cell carcinoma were followed. The most common primary tumor location was palate. The result of this study was compared with other previous reviews and showed some differences.

Two dogs were presented with a history of anorexia, respiratory distress, or epistaxis. On physical examination, the dogs showed difficulty breathing and open-mouth breathing and large masses were found on the hard palate and soft palate. Cardiac arrest happened in case 2 and the dog was stabilized with cardiopulmonary resuscitation and oxygen therapy. Computed tomography demonstrated that the mass occupied the oropharynx, intrapharyngeal ostium, and laryngopharynx including the hard palate and soft palate in case 1. Palliative surgery was decided to improve swallowing and breathing with owner's consent in two dogs. Buccal mucosal flaps were performed for reconstruction of defects using rotational and single-pedicle advancement flaps and bilateral 90 degree transposition flaps in cases 1 and 2, respectively. Histopathology results described the oral masses as amelanotic melanoma in two dogs. The owners reported that there was normal swallowing and breathing at 7 days postoperatively in two dogs. In case 1, recurrent tumor was identified caudal to the hard palate 4 weeks after surgery. The owner did not allow further treatment and the dog became lost to follow-up at 2 months postoperatively. In case 2, there was no clinical or radiographic evidence of a local recurrence or distant metastasis at 3 weeks after surgery. The owner informed that the dog died suddenly with no signs of anything particularly wrong at 7 weeks after surgery.

Minor salivary gland tumors vary in their primary sites, histopathology and bilogical behavior. Therefore various factors are considered in selecting the treatment modality and predicting the prognosis. The prognosis of milignant tumors of minor salivary glands are worse than that of such lesions of major salivary glands. Authors experienced 26 cases of minor salivary gland tumors(10 benign tumors and 16 malignant tumors) during the past 7 years and analyzed their clinical characteristics. 1) The palate was the most common site of origin of minor salivary gland tumors (38.5%). 2) The most common benign tumor was pleomorphic adenoma and majority of them occur red in the palate(60.0%) and the remaining occured in the nasal cavity or the paranasal sinuses (30.0%), and the lip ( 10.0%). 3) In the case of malignant tumors the most frequent sites were the nasal cavity or the paranasal sinuses (31.3%) with the following histopathologic frequencies: adenoid cystic carcinoma(56.3%), malignant pleomorphic adenoma(12.5%), mucoepidermoid carcinoma(12.5%), polymorphic adenocarcinoma (12.5%), epthelial-myoepithelial carcinoma (6.25%). 4) Minor salivary gland tumors have high probability of malignancy and tumor extension is important to their treatment.

The nasolabial flap is a well-known one for regional repairs. When the inferior-based nasolabial flap was used, the beard area was avoided, and subcutaneous flap pedicle versatility was increased. The inferiorly-based nasolabial flap with a subcutaneous pedicle was useful in the primary repair of surgical defects of the floor of mouth. maxillary alveolus, palate. and tonsillar area in selected patients.

신경초종은 천천히 자라는 양성종양으로 뇌신경, 말초신경, 또는 자율신경 등 신경초세포(Schwann cells)를 포함한 신경 어디에나 발생할 수 있다. 대부분의 신경초종은 무증상이며, 악성화되는 경우는 드물다. 전체 신경초종 중 약 25%에서 45%가 두경부 영역에서 발생하지만 구강 내 발생하는 경우는 거의 없는 것으로 알려져 있다. 구강 내 신경초종의 대부분은 설부에서 발생하며 그 외 발생하는 부위로 협부점막, 구개, 구강저, 잇몸, 입술 등이 있다. 본 저자들은 최근에 경구개에 발생한 신경초종 1예를 경험하였으며, 이를 관련문헌 고찰과 더불어 보고하는 바이다.
