There have been few large scale surveys of salivary gland tumors, because the salivary gland tumors comprised less than 3 percent of all neoplasms of the head and neck. Also there is a problem that the incidences of specific types of tumors have the variation according to the geographic regions. ]'nother Korean reports about salivary gland tumor, they only treated about 100 cases only. Objectives : The purpose of this study is to identify the frequency and clinical characteristics of salivary gland tumors and to compare with other Korean reports. Materials and Methods : We had performed to analyze 387 cases of salivary gland tumors from 1983 to June 1997, were reviewed in histopathological and clinical aspects. The diagnoses of individual tumors were based on the World Health Organization classification. Tumors were analyzed according to the histologic type site, age and sex. Results : The majority (79.1%) of cases occurred in the major salivary glands and 20.9% in the minor. The parotid gland was the most frequent site with 52.4% and submandibular glands with 26.3%. Benign tumors were 79.3% of the tumors and malignant tmon were 20.7%. The most frequent tumor was pleomorphic adenoma occupied 63.8% of the total and frequency percent of histologic type of 98 malignant tumors showed 35.7% of mucoepidermoid carcinomas, 24.5% of adenoid cystic carcinomas. Overall gender with female predominance with 1 : 1.4 of male to female ratio. The average age of patients was 42.8 years. The most frequent chief complaint was a palpable mass. The duration of the symptom was shorter in the malignant salivary gland tumors (26.7 months) than in the benign salivary gland tumors (38.2 months). Conclusion : Comparing to the previous Korean reports, the present study confirms that the incidence of salivary gland tumor was lower in the parotid gland, and was higher in the submandibular and minor salivary glands.

Background and Objectives:Obstructive lesion of salivary glands by salivary duct calculi and stenosis is the main inflama-tory disease of major salivary glands. Recently, the sialendoscopy has been introduced for the diagnosis and intervention of tory salivary gland diseases. Subjects and Method:Diagnostic and interventional sialendoscopy were performed in 19 patients (7 parotid glands, 12 submandibular glands), who had salivary duct calculi or recurrent sialadenitis without calculi from 2003 Sep. to 2004 Jun. Diagnostic sialendoscopy was performed for obstructive lesions and evaluation of ductal status. Interventional sialendoscopy was performed for the removal of salivary duct calculi and dilatation of duct stenosis in cases with calculi and stenosis. Results:3 glands had sialadenitis with no evidence of obstruction. Only one case with salivary duct calculi was failed. The remaining 10 calculi were removed with microforceps and basket with or without laser fragmentation. The average size of sialoliths was 5.2 m and multiple stones were found in 2 cases. Five cases with stenosis of parotid and submandibular gland duct were dilated with balloon catheter or endoscopy sheath successfully. In the remaining 3 glands with no obstruction, the finding of ductal in-flamation was identified. No major complications were noted. Conclusions:Diagnostic sialendoscopy is a new and minimal allows the extraction of salivary duct calculi in most cases and the dilatation of stenotic duct. This technique might be useful in preventing open gland surgery in well indicated cases.

타액선 종양의 치료지침

박윤규(Yoon Kyu Park) 대한두경부종양학회 1993 대한두경부 종양학회지 Vol.9 No.1

The salivary gland consists of major and minor glands. The major glands are parotid, submandibular and sublingual glands. The numerous minor salivary glands are located in the mucosa of the upper aerodigestive tracts. Tumors of the salivary gland are relatively uncommon, and the incidence of the salivary gland tumor among the head and neck neoplasm is approximately 3%. Surgery is the primary treatment of choice for the most tumors of the salivary glands. Author reviewed the recent reports of salivary gland neoplasms of Korea and foreign institutes and suggest the guideline of managemnt of salivary gland tumors.

Background and Objectives :This study reports our clinicopathological experiences of major salivary gland tumors. Materials and Methods :This study included 302 patients with major salivary gland tumors who had got the diagnosis from January 1995 through December 2004. Medical records were reviewed retrospectively. Results :We found 244 benign and 58 malignant major salivary gland tumors. Among 267 parotid tumors, the most common benign parotid tumor was pleomorphic adenoma. Mucoepidermoid carcinoma, adenoid cystic carcinoma, and acinic cell carcinoma were three most common parotid malignancies. Among 33 submandibular gland tumors, 20 cases were benign and 13 were malignant. There were one benign and one malignant su-blingual gland tumors. The duration of symptom of submandibular gland tumors was longer than that of parotid tumors. Most patients presented with asymptomatic mass. Seventy-one percent of salivary gland malignancies underwent postoperative radiation therapy. Five-year disease free survival rate of parotid malignant tumors seemed to be higher than that of submandibular one, although there was no statistical significance. Conclusion :Malignancy rate of each salivary gland followed old axiom that it is inversely related with the size of gland. Submandibular gland tumor tends to be delayed to reach diagnosis. Clinicians must be alert about this finding because submandibular gland tumors are known to have poorer prognosis than parotid tumors.

Currently, there has been rapid increase in the studies about salivary production because of the hyposalivation, xerostomia, caused by radiotherapy for head and neck cancer, Sjogren syndrome and aging. An overview of anatomy and development of salivary gland is crucial to understand about the patho-physiological disorders related with saliva. For study of the morphogenesis and development of salivary glands, experiment using rodent models is widely necessary. This review wraps up the early to latest studies - the different features of each salivary gland, morphogenesis of developing salivary glands, and the comparison of human and rodent salivary glands. The goal of this review is to provide hypothesis for the further researches about differentiation of specific acinar cells, from which it is determined to be specific acini. Additionally, we discuss approaches to regenerate the function of salivary glands using environmental factor, time dependent factor and nerve factor.

Pleomorphic adenoma is the most common salivary neoplasm mainly occurring in the major salivary glands - especially in parotid gland, which is characterized by variable histopathologic appearances and high recurrence rate with malignant transformation according to surgical situations. And this benign mixed tumor occurring in minor salivary glands is believed to shows same clinicopathologic appearances and relatively low recurrent rate compared with the case in major salivary glands. But there are few comparative studies of large series of pleomorphic adenoma occurring in minor salivary glands which includes different histopathologic appearance, clinical characteristics, treatment methods, recurrence rate, and malignant transformation. We retrospectively studied the 54 patients who were pathologically confirmed with pleomorphic adenoma occurring in minor salivary glands, and analyzed the clinico-histopathological appearance, surgical methods, recurrent cases. The results obtained are as follows. 1. The incidence of the tumor was most frequent in 4th & 5th decade, and in female. 2. Palate(90%) including hard & soft palate was the most frequent site for pleomorphic adenoma in minor salivary glands. 3. The exact duration could not be known due to asymptomatic slow growth patterns of the tumor. 4. The mean tumor size was 2.3cm. 5. 28 (52%) pleomorphic adenomas were classified as Cellular type (cell-rich), 17 (31%) specimen as Intermediate type(equal cell to stroma ratio), and 9 (17%) as Myxoid type(stroma-rich). 6. Surgically 51 cases (94%) were showed well-encapsulated tumors, but histopathologically only 34 specimen (63%) were wellencapsulated. Therefore pleomorphic adenomas in minor salivary glands also have to be excised more widely, not enucleated. And in case of suspicious malignancy or large tumor, preoperative incisional biopsy can be applied in the center of the tumor for prevention of rupture of tumor cell, and total excision with use of frozen biopsy for detection of malignancy and confirming the excision margin, and closed follow-up according to final histopathologic results is recommended.

악하선 분비관의 결찰 후 타액선 조직의 변화

차승만(Seung-Man Cha),정인교(In-Kyo Chung) 대한구강악안면외과학회 2005 대한구강악안면외과학회지 Vol.31 No.5

Obstructive adenitis of the salivary gland following salivary stone or infectious disease of the gland and surrounding tissues is a common disease. It is often difficult to decide whether to perform total excision of the gland or to consider conservative treatment. The present study was designed to investigate histological, histochemical changes of submandibular gland after ligating the excretory duct for identifying the results of gland duct obstruction. A group of 40 rat of Sprague-Dawley weighing about 200~220gm were used in the present study. 30 rats had ligation of the main excretory ducts of submandibular glands just at the exit from the glands. For controls, 10 rats had a sham operation without duct ligation. They were inducted into euthanagia state by intracardial Ketamine injection in 1, 2, 3, 5, 7, 14, 21, 28, 35 and 42 days after the ligation. In each ligation period, 3 animals were used for ligation and one animal was for control. The submandibular glands were dissected out at sacrifice and stained with H&E, PAS, mucicarmine stain and histological examination were carried out under the light microscope. After examination and comparison of all specimens, the results were as follows: 1. In the features of H&E stain, acini disappeared by degrees after the ligation of the excretary duct and interstitial cells were displaced into fibrous connective tissue. Salivary gland had been atrophied with enlarging ducts and proliferating ductal cells. 2. Through total experimental period, a lot of vessels were observed and the atrophy of serous gland was severer than that of mucous gland. 3. The deep portion of submandibular glands showed severe degeneration rather than superficial portion of them after the ligation. 4. The changes which had enlarged ducts and proliferating ductal cells were observed in entire gland and more prominent in serous gland than mucous gland after the ligation. 5. Although PAS and mucicarmine reactions were decreased gradually after the ligation with the lapse of time, since 2 to 3 weeks they were strong positive reactions on entire gland, especially on duct-like structure. So, we can suggest that salivary gland will be atrophied but, survived acini will be redistributed around the ducts.

Purpose: Sialolithiasis is one of the most prevalent large obstructive disorders of the submandibular glands. The aim of this study was to investigate submandibular sialolithiasis with computed tomography (CT) and scintigraphy, with a particular focus on the relationship between CT values of the submandibular glands and their excretion rate. Materials and Methods: Fifteen patients with submandibular sialolithiasis who underwent CT and salivary gland scintigraphy were included in this study. The relationship between the CT values of submandibular glands with and without sialoliths and salivary gland excretion measured using salivary gland scintigraphy was statistically analyzed. Dynamic images were recorded on the computer at 1 frame per 20 seconds. The salivary gland excretion fraction was defined as A (before stimulation test [counts/frame]) / B (after stimulation test [counts/frame]) using time-activity curves. Results: The CT values in the submandibular glands with and without sialoliths was 9.9±44.9 Hounsfield units (HU) and 34.2±21.8 HU, respectively (P=.233). Regarding the salivary gland excretion fraction using scintigraphy, the A/B value in the submandibular glands with sialoliths (1.09±0.23) was significantly lower than in the submandibular glands without sialoliths (1.99±0.57, P=.000). Conclusion: Assessments of the CT values and the salivary gland excretion fraction using scintigraphy in the submandibular glands seem to be useful tools evaluating submandibular sialolithiasis.
