Abstract
Sialolithasis occurs due to the calculous concretion in salivary ducts or glands, but it is rare in childhood.
In this paper, a case of sialolithisis with a parotid gland calculous observed in 3-year and 10month old girl is reported. Subject is one of the youngest, based on a review of the literature regarding sialolthiasis found in Japan.
The retrospective survey was made in 23 cases of sialolithiasis in children under 10 years of age which were reported in the Japanese literature with clear descriptions of age, sex and location.
The summaries are as follows:
1) Sex difference: The difference between males and females was in the ratio 12/11. There was no significant difference according to sex.
2) Location of the salivary calculi: In 20 cases they were found in the duct of the submandibular glands, and in 3 cases in the parotid glands, and in no cases in the sublingual glands.
3) Term before treatment: Most cases were treated within a month after the patients had noticed the symptom.
4) Removal method of salivary calculi: Salivary calculi were removed by means of intraoral incision in most cases.
5) Number of the removed calculi: In each of all cases, one calculous was removed.
6) Size of the removed calculi: The diameter of the calculi was less than 5.0 milimeters long in most cases, but in two cases of the parotid duct they were more than 5.0 milimeters long.
