악하선계 타석증의 임상적 연구

Abstract

The salivary stone consists of molecules of abnormal mucoid material coalescing into a gel and eventually into a laminar structure, not an uncommon condition encountered in practice. The salivary stone may found in all the salivary glands or ducts, but the larger proportion in the submandibular gland or duct. Authors performed the analysis of 18 cases of the salivary stone which were diagnosed and treated from March 1989 to May 1994 at our department. The results were as follows; Age and sex distributions were more predominantly third decade(55.5%) and male(55.5%), respectively. Site distributions were more common at submandibuar duct(72.2%) and Left side(66.7%)· Number of stone was from 1 to 2, and 15 cases(83.3%) were single stone. Size was diverse from 2 to 15mm in the longest diameter and 12 stones(57.1% ) were from 5 to 9mm. 14 stones(66.7%) had yellow color. The clinical symptoms were 10 cases(55.6%) of submandibular swelling, 8 cases(44.4%) of painful swelling of submandibular area at meal, 3 cases(16.7%) of odynophagia, 2cases(11.1%) of submandibular area and mouth floor pain, and 1 case(5.6%) of fever and chilling sensation. Among diagnostic methods of the salivary gland stone, the plain x-ray and sialogram were very important. The 16 cases(88.9%) were treated by submandibular gland resection and 2 cases (11.1%) by intraoral removal.
