    Author: Kang SK, Kim KS.

    Abstract:
    Mucoceles are commonly occurring lesions of the oral mucous membrane and the most common lesion involving minor salivary tissue. The incidence of mucoceles is understandable since accessary salivary gland tissue is widely distributed throughout the oral mucous membrane and trauma to the mucosa, which causes their formation, occurs frequently. But only a few studies have been reported that describe its detailed features. This is a retrospective study on the salivary mucoceles in the oral mucous membrane and based on clinical chart, biopsy request and photomicroscopic finding of 112 patients treated by Dept. of Oral Surgery in Seoul National University Hospital, during the period of last 10 years. The results were as following. 1. The age range of the 112 patients was 2 to 60 years, with a peak incidence in the second decade and a gradual decline thereafter. Of the 112 patients, 49 (44%) were males and 63 (56%) were females, the male-to-female ratio being 1:1.29. 2. The majority of these lesions were located on the lower lip but occurred with lesser frequently on the buccal mucosa, floor of the mouth, tongue, retromolar region, upper lip. 3. Of the 112 patients, 107 (95%) were treated by excision and only 5 were treated by marsupialization. 18 of 112 cases had recurrence and the recurrence rate in this study was 16%. 4. Only 3 of the 112 cases revealed an epithelial lining. This incidence indicates that the mucus-extravasation by the damage of excretory duct rather than the ductal dilatation by mucus-retention may play a critical role in the production of these lesions. 5. In 81 cases (72.3%) minor salivary gland were included in the excision biopsy, specimen. Changes observed in the glandular tissue were atrophy and infiltration of chronic inflammatory cell, but the secretory function of gland was thought to be normal in most cases because the changes were mild.
