Comparative study of primary intention lacrimal probing with and without nasal endoscopy.

Objective: Our objective was to compare the results of probing with and without endoscopy in cases of congenital nasolacrimal duct obstruction without prior probing.

Methods: This was a retrospective analysis on 2 non-randomized cohorts, 36 simple soundings (group 1) and 36 soundings with endoscope (group 2), between January 2011 and January 2013. Both groups were similar in age and had no previous surgery.

[Treatment of the congenital obstruction of the lachrymal duct, by means of balloon catheter, monocanalicular intubation, and endoscopic control].

Introduction And Goals: Congenital lachrymal obstruction is a frequent motive of consultation. Endoscopic control in the inferior meatus of the nostril allows to realize surgical controlled procedures. The aim of the study is to analyze the result obtained in the treatment of congenital obstruction of the lachrymal duct by monocanalicular intubation with Monoka and endoscopic control in children who had failed two lachrymal system probings.

[Conjunctivodacryocystorhinostomy with the assistance of diode laser. Endoscopic placement of Jones lacrimal tubes].

Objective: To describe and assess a surgical technique for cases of complete bicanalicular lachrymal destruction by means of the endoscopic insertion use of the Jones tube with a diode laser to study functionality and complications.

Patients And Method: A descriptive study of a case series with 24 consecutive patients with complete bicanalicular obstruction who underwent conjunctivodacryocystorhinostomy with diode laser. The surgery time, intra-operative and post-operative complications, long-term patency, and need for secondary revision were evaluated.

[Comparative study between auditory steady-state responses, auditory brain-stem responses and liminar tonal audiometry].

Objectives: Auditory steady-state responses (ASSR) using frequencies of modulation between 70-110 Hz are a new auditive exploration technique. The aim of the study was to evaluate the contribution of the ASSR to diagnostic of the audition.

Material And Method: Different aportations of auditory steady-states responses (ASSR) and auditory brain-stem responses (ABR) to diagnostic of threshold of audition were studied Differences between these thresholds and thresholds obtained by liminar tonal audiometry (LTA) were studied too.
