Pit of the lower lip » Mouth Q38.0


Para-medial sinus, pit or fistula of the lower lip that when epithelized forms a mucous cyst. Lip printing can be a simple, noninvasive way to document this abnormality.
ICD10 lacks a specific code and considers them as lip anomalies not classified elsewhere [Q38.0].
Lower lip pits in patients with oral clefts or their relatives suggests the diagnosis of Van der Woude syndrome {OMIM 119300}, which is the most frequent syndrome among oral cleft cases.
