[A modification of Toti's operation (author's transl)]. 1977

F Hollwich

An external dacryocystorhinostomy with simplified suture is described. This method was suggested in 1937 by Kaleff and further developed by us. The modified operation consists of the following: The nasal mucous membrane is prepared free, and from this a complete pedicle is made with the base underneath. The tear sac is split in the long axis into a broad upper and a narrower lower part. The narrow lower part is sewed to the nasal mucous membrane with 3 atraumatic catgut sutures. The broader upper lobe of the sac is fixed to the covering subcutis with 3 catgut sutures.
