Definitive treatment of congenital larcrimal sac fistula
A. R. Caputo, N. H. Smith, A. A. Cinotti and D. Angiuoli
The procedure we describe is believed to be a rational and effective
approach to the rare but preplexing problem of congenital lacrimal sac
fistula. The procedure is based on the principles of: (1) definite location
of the lacrimal sac for protection of canaliculi and sac through probe
insertion; (2) fastidious dissection of the tract to its base; and (3)
positive testing of the suture and sac site for leakage.
