More than 30 years of rapid development of endoscopic surgery has led to the mainstreaming of this procedure in many surgical departments in China. Since the first report on endoscopy, it has been used in salivary gland resection for more than 20 years. The overall development of endoscopic surgery indicates that its use in oral and maxillofacial surgery is still in the early exploration stage; it has not yet been maturely developed or applied. Owing to the advancement of other disciplines and corresponding widening experiences in those fields, the development of endoscopic technology in oral and maxillofacial surgery will likely achieve a leapfrogging. Learning from the general development pattern of endoscopy, this research explores the application history, current situation, and future direction of the application of endoscopy in salivary gland surgery.

salivary gland in the field of Oral & Maxillofacial surgery. Obstruction of salivary secretion by a sialolith can result in swelling and pain, as well as infection of the gland. The swelling is usually correlated to meals, when salivary secretion is enhanced. Sialolithiasis occurs mainly in the submandibular gland(92%) and to a lesser degree in the parotid gland(6%). The sublingual gland and the minor salivary gland are rarely affected(2%). This is a report of rare case, the authors have experienced, within the left sublingual gland and the minor salivary glands. It is multiple sialolithiasis(about 22 silaoliths) in the sublingual and the minor salivary glands which has very low incidence of sialolithiasis. The pathosis were removed using transoral sialolithotomy with sublingual sialadenectomy.]]>

The face and notably the lips are important structures not only of aestheticvalue but also for expression, vibrancy and vitality. Sometimes we are encountered with the functional and aesthtetic lip problems especially in the patients with mandibular prognathism, such as excessive vermilion exposure, lip incompetence and hyperactivity of mentalis muscle. The etiologic factors are usually related to excessive anterior facial height, secondary to the abnormal development of perioral muscle, salivary gland and the swelling of lymphatic gland. Sometimes orthognathic surgery (mandibular setback osteotomy) alone is not accepted regarding to aesthetic value, there is likely to be a corresponding interest in adjunctive procedures such as genioplasty and soft tissue procedures. This article urges the incorporation of reduction cheiloplasty. It is a relatively minor procedure that can be easily reproducible and yields excellent, predictatable results with few complications. We treated two patients who have excessive vermilion exposure and marked abnormal lip eversion using reduction cheiloplasty combined with mandibular setback osteotomy, followed by improved facial harmony and patients were pleased.

Salivary glands, major and minor, are susceptible to a wide variety of pathologic conditions. Excision of the submandibular gland is a surgical procedure often undertaken. The procedure is the treatment of choice for patients with neoplasm of the submandibular gland and those with non-neoplastic submandibular disorders which are not controlled with conservative medical measures. Extirpation of the submandibular gland may also be undertaken for diagnostic purposes. We evaluated 84 patients who had been admitted to the Dept. of oral and maxillofacial surgery of Pusan National University Hospital from January, 1989 to December, 2002 and had been performed submandibular gland excision. The results are as follows : 1. The patients undertaken the excision of the submandibular gland showed an age range of 16 to 71 years. The average was 49.1. 2. They consisted of 60 males(71.4%) and 24 females(28.6%), having 2.5 : 1 of genda ratio. 3. The most common symptom was swelling in 41 cases(48.8%), followed by the pain in 23 cases(27.4%). Other symptoms included mass, dysphagia, facial abnormaly and neck dyscinesia. 4. 42 cases(50.0%) showed sialadenitis and sialodochitis associated with salivary calculus. 5. According to the histopathologic study, all cases consisted of 17 neoplasmatic conditions(20.3%) and 67 non-neoplasmatic(79.7%). The neoplasmatic cases included 13 benign tumors and 4 primary malignant tumors. Sialadenitis and sialodochitis associated with or without salivary calculus were most marked, found in 50 cases(59.3%), in the non-neoplasmatic conditions. Pleoomorphic adenoma showed the highest frequency of the benign tumor.

The submandibular gland is the second largest major salivary gland, which secretes 40% of the total daily saliva. Owing to its anatomic characteristics as well as the high viscosity and basicity of the saliva, sialolithiasis is found most commonly in the submandibular gland. Sialolithiasis that cannot be treated by conservative treatment is conventionally removed by an excision of the submandibular gland. Generally, an excision of the submandibular gland is performed via an extra-oral approach but the disadvantages of this treatment include a risk of injuring the facial nerve and scar formation. Case reports have revealed an even less invasive intraoral surgical technique for the removal of sialolith that does not affect the submandibular gland function. The functional recovery of the gland, complications and recurrence rates after surgery with this conservative intraoral procedure were all successful. We report 5 patients from the department of Oral and Maxillofacial Surgery at Dental Hospital, Yonsei University, who had undergone a resection of the sialolith though the intraoral approach with successful results.

INTRODUCTIONClear cell carcinoma is a rare low-grade carcinoma that almost exclusively occurs in the minor salivary glands. This tumour is one of the new additions in the recent World Health Organization (WHO) classification of salivary gland tumours.

CLINICAL PICTUREA 50- year-old woman presented with a gradually enlarging painless submucosal mass of 3 months' duration over the left side of the palate.

TREATMENT AND OUTCOMEA preoperative diagnosis of primary clear cell carcinoma of salivary gland with focal surface epithelial dysplasia was rendered after thorough clinical examination to rule out renal origin. The lesions were excised with wide surgical margins and 3 years into the postoperative period, the patient was disease-free.

CONCLUSIONWe report a case of clear cell carcinoma of intra-oral minor salivary gland and draw comparisons with metastatic clear cell carcinoma of renal origin.

Pleomorphic adenoma is the most common salivary benign tumor, constituting over 60% of parotid gland tumor, 25% of sublingual gland tumor and 50% of minor salivary gland tumor. It is somewhat more frequent in the fourth to sixth decades. The recurrent rate which enforces only a simple enucleation is very high (20.45%). Histologically, it contains the epithelial cell, the myo-epithelial cell and mesenchymal ingredient, which is various aspect. We analyzed clinicopathologically and immunohistochemically the patients(34 cases) who are diagnosed with pleomorphic adenoma in Department of Oral and Maxillofacial Surgery, College of Dentisty, Dankook university since 1998. The results are as follow: 1. The incidence of the tumor was most frequent in age 30 to 50. The ratio of male to female was 1:1.43. 2. The most chief complain was a painless mass(94.1%) and the duration time was more than decade in 18 cases(52.9%). 3. Palate(soft and hard palate) was the most occurred site(64.7%). In major salivary glands, the parotid gland was the most frequent site(17.6%). 4. The tumor size was 2 to 3cm on the average. Most of tumors were with capsule(91.2%). 5. Surgical excision was a main treatment method(20 cases, 58.8%) and 14 cases were excised with a glandectomy, 1 case was treated with a partial maxillectomy. Only 1 case of all cases was recurred. 6. Histopathologically, 9 cases(26.5%) were cellular type, 11 cases(32.4%) were intermediate(classic) type and 14 cases(41.1%) were myxoid type. 7. Immunohistochemically, the specimen of all tumors reacted positively to cytokeratin and vimentin marker.
