Congenital lower lip fistula is a comparatively rare malformation. We report here 2 such cases accompanied by cheilognathopalatoschisis. Besides, some additional consideration in the literature was given to a total of 102 cases including cases found between 1933 and 1986 and 2 cases of ours.<BR>Our 2 cases were males, whose hereditary backgrounds remained uncertain. Two fistulas of about 10mm depth were found bilaterally at the central prolabium of the lower pit. These fistulas, which showed discharge of mucoid fluid upon compression, were totally resected according to Kaptanskys method.<BR>Cases reported in our country comprised of males and 46 females with one unknown sex, 81 of which had 2 fistulas. Inter-fistular distance averaged about 8mm, and fistulas with mention of the depth amounted to 63 with an average inter-fistular distance of 8.2mm.<BR>About half of the patients with this malformation had some cleft malformations within their identical lineages. Surgical resection was most frequently adopted.
