[Malformation of the tear ducts associated with clefts in the face (author's transl)].

A case of malformation of the tear duct associated with clefts in the face is described. To our knowledge this combination has not been described before. The whole symptoms complex consisted of: bilateral cleft lip upper jaw and gum, choanalatresia, mucocele of the left nasal cavity from adhesions of the lower concha with the nasal septum, cystic dilatation of the tear sac at the connection to a bony naso-lacrimal duct. Right inguinal hernia, syndactyly of the first and second left toes, iris-chroid coloboma right with congenital cataract and unilateral right convergent squint. Because of the advanced dacryocystitis on the basis of the congenital dacryostenosis, and external dacryostorhinostomy (modified after Kaleff 1937) was performed after pre-treatment by instillation of antibiotic solutions in the tear ducts. At the same time the nasal cavity mucocele was opened by partial excision of the lower concha and opening the choanal atresia. After a post-operative course free of complications and with clear patency of the tear ducts the oral surgical operation was done--closure of the face clefts. The chromosome analysis was normal the only abnormal result here was an unexplained slow rate of multiplication of lymphocytes in four cultures inoculated at various points of time. Because we could not find any hereditary factors, this symptom complex is probably due to exogenous embryo damage during the early development phase.
