[Endonasal dacryocystorhinostomy: a personal experience].
Stenosis of the naso-lachrymal duct as a consequence of acute or chronic inflammation, trauma or congenital malformation is a relatively frequent lachrymal duct pathology. The symptoms include epiphora and intermittent tumefaction of the medial ocular canthus, indicative of a deficiency in lachrymal drainage. If such conditions do not respond to medical treatment, lavage and transcanicular probe, surgery proves necessary. Modern techniques for endonasal surgery place the otologist in the forefront in the surgical treatment of this disorder. Endonasal dacryocystorhinostomy (DCR) is indeed a valid alternative to traditional extra-nasal surgery; once exclusively the domain of the ophthalmologist. However, it does require a certain expertise in micro-endoscopic surgery. In most cases sophisticated equipment is not required and the procedure can be performed with just a few instruments: electric knives, scalpel and Citelli forceps. Endonasal DCR makes skin incisions unnecessary and makes it possible to reveal, and possibly, correct, any sequela subsequent to traditional DCR such as ethmoidal rhino-sinusitis or the presence of adhesions. In the present work 67 patients--24 with recurrence after traditional surgery--underwent endonasal DCR within the last 22 months and with an average follow-up of one year. Surgery was successful in 90% of the cases.
