Abstract
In the Out-Patient Department of Oral Surgery we daily come across salivary cysts which we treat surgically - by scaling or marsupialisation.
We considered that it would be helpful to analyse these changes clinically, histopathologically and pathogenetically.
There are two types of salivary cysts: retention cysts (histologically a salivary gland with dilated secretory canals lined with large cells with honeycomb cytoplasm) and extravasation cysts (a hollow mass filled with cellular detritus and bacteria, coated with cylindrical and stratified epithelia).
Mucocele are coated with a lining of granulation tissue and contain eozinophyllic hyaline material. They occur throughout the whole of the mucous membrane of the oral cavity, although the majority are on the lower lip. They most frequently occur because of mechanical injury to the secretory canals of the small salivary glands and retention. They are approximately 1.5 cm in diameter. They cause slight cyanosis of the area and bluish-white surface which occurs as a result of the narrowing of the blood vessels and thin walls of the mucocele.
We retrospectively analysed histopathological findings with a clinical diagnosis “mucocele” during the period 1 January 1995 to 31 December 2000. During that period a total number of 9047 people were operated. Of 1358 findings sent for histopathological analysis (PHD), 89 were clinically diagnosed as mucocele. Of these 89 lesions in only 72 cases was the diagnosis of mucocele confirmed histopathologically. Differences in gender did not essentially have an effect on the occurrence of mucocele, and according to the results of the investigation we found that although mucocele occurs in all age groups, it is more frequent in younger people during the second and third decade of life. In our investigation mucocele were largely located on the lower lip, 83.3%. Other mucocele were located in the sublingual space, on the mucous membrane of the cheek and in the vestibulum of the oral cavity. According to the histopathological description we concluded that 23 mucocele were of retention type and two extravasation lesions.
