Resumen
Objetivo

Detallar las maniobras quirúrgicas y valorar los resultados tras la realización de dacriocistorrinostomías endonasales y endocanaliculares con láser diodo, incluyendo las ventajas y restricciones de esta cirugía

Método

Se practican 34 dacriocistorrinostomías endonasales y endocanaliculares con láser diodo bajo anestesia tópica y local en pacientes con clínica de epífora, con o sin secreción mucopurulenta, por obstrucción a nivel del conducto nasolagrimal. El estudio es prospectivo, intervencional, no randomizado y no comparativo. Se realiza vaporización de saco lagrimal, la osteotomía y la vaporización y coagulación de mucosa nasal con el láser diodo. El tiempo quirúrgico medio fue de 15 minutos (rango 9 - 25 minutos). En todos los procesos se efectúa intubación bicanalicular con tubos de silicona e hilo de prolene durante dos meses. El periodo observacional postquirúrgico fue entre 4 y 11 meses. En todos los pacientes se valoró el grado de epífora mediante la escala de Munk y la permeabilidad lagrimal con el test de tinción funcional endoscópica

Resultados

De las 34 dacriocistorrinostomías endonasales y endocanaliculares, permanecen asintomáticos 32 casos (94,11%). Dos (5,88%) pacientes precisaron de dacriocistorrinostomía endonasal con fresado por imposibilidad de perforación ósea con la fibra del láser. Dos casos (5,88%) presentaron fibrosis y obstrucción del punto lagrimal y canalículo inferior, estando sin epífora por permeabilidad del trayecto superior

Conclusiones

La dacriocistorrinostomía endonasal y endocanalicular con láser diodo es un procedimiento válido que no origina cicatriz en piel, disminuye el daño térmico canalicular, respeta el bombeo lagrimal excretor, minimiza el dolor y sangrado, y reduce el tiempo quirúrgico, siendo una cirugía ambulatoria con morbilidad operatoria y postquirúrgica mínima

Abstract
Aim of the study

To describe the surgical technique and to evaluate the clinical results after having performed the transcanalicular and endocanalicular dacryocystorhinostomies by diode laser, including the advantages and limits of this technique

Methods

34 were performed by diode laser in patients with clinical history of epiphora, with or without mucopurulent secretion, for nasolacrimal duct obstruction. The study was prospective, interventional, non randomized and non comparative. Diode laser was used to realize vaporization of lacrimal sac, osteotomy and vaporization with coagulation of nasal mucosa.The mean of surgical time was 15 minutes (range 7 to 29 minutes). Bicanalicular intubation was permormed with a silicone tube and prolene filament for two months in all cases. Postsurgical follow-up was between 4 and 11 months. The degree of epiphora was evaluated by the Munk scale and lacrimal permeability was evaluated by endoscopic functional staining test in all cases

Results

Out of the 34 DCR-EDN+ENC that were performed, 32 cases (94.11%) remain asymptomatic. Two of them (5.88%) required endonasal dacryocystorhinostomies by drilling, because the bony perforation was impossible to achieve by laser fiber.Two cases (5.88%) presented fibrosis and lacrimal and lower canaliculi obstruction, without epiphora because the superior canaliculi was permeable

Conclusion

Endonasal and endocanalicular dacryocystorhinostomy technique performed by diode laser is a valid method. It does not cause cutaneous scarring, it decreases thermic canalicular damage, it respects the lacrimal pump, it minimizes pain and bleeding, it needs less surgical time and it has turned into an out-patient procedure with a minimal surgical and postsurgical morbility
