[Raverdino's operation, a procedure to resolve lacrimal dacryostenosis with deficient pituitary mucosa]

The paper presents the efficiency of the Raverdino operatorial technique, which creates a large anastomosis between the lacrimal sac and nose, followed by an effective drainage in those cases with persistent obstruction of the nasolacrimal duct. The paper also exposes clinical cases in which the mentioned technique was used as first intervention or as reintervention after an inefficient dacryocystorhinostomy. The Raverdino technique offers a successful, long lasting result, without major intra- or postoperative complications.
