The nasolacrimal apparatus is intimately associated with the lateral nasal wall and may be approached using an endoscopic technique. This study was undertaken to describe in detail the gross anatomy of the nasolacrimal duct orifice in relation to various landmarks of the lateral nasal wall to improve the safety and efficiency of endoscopic surgical procedures. The study was conducted on 25 sagi...

Introduction: This study was done to determine the site of obstruction in lacrimal drainage system in Asian patients suffering from epiphora and to determine the transit time taken for the tracer material to reach the lacrimal sac and the nasal cavity. Methods:Dacryoscintigraphy was performed using radionuclide technetium-99m pertechnetate (99m...

Purpose: To investigate whether neonatal dacryocystoceles and dacryocystitis are associated with nasolacrimal duct cysts, and to report the outcomes of treatment of these disorders. Methods: This was a retrospective medical record review of two groups of infants with nasolacrimal duct (NLD) obstruction. The first group had dacryocystoceles with or without dacryocystitis. The second group had NL...

UNLABELLED The anatomical relation between the maxillary sinus and the nasolacrimal duct has gained greater importance with the advent of microsurgeries and endoscopic-assisted sinonasal procedures, and the growing use of endonasal surgery to perform middle meatus procedures and transnasal dacryocystorhinostomy. We did not find reports on maxillary sinus classification concerning its lacrimal r...

Aims and Objectives: To compare the success rates of non endoscopic endonasal dacryocystorhinostomy and conventional external dacryocystorhinostomy for the surgical management of primary acquired nasolacrimal duct obstruction. Materials and methods: A retrospective, nonrandomized, comparative interventional case series of 302 patients who underwent either endonasal or external dacryocystorhinos...

Linear compartmental analysis was applied to lacrimal scintigraphy data from asymptomatic and obstructed lacrimal systems. Failure to achieve satisfactory results in most of the asymptomatic systems studied suggests that variable tear flow is a feature of normal lacrimal drainage which precludes linear analysis. However, in cases where the analysis was successful the results were consistent wit...

Chronic dacryocystitis results very often from obstruction to the nasolacrimal duct. It manifests as epiphora or watering of the eyes. The lacrimal sac gets expanded and also the wall of the sac gets thickened as a result of collection of mucopus due to obstruction of the nasolacrimal duct. Treatment of chronic dacryocystitis is by a surgical approach which consists of making an opening between...

PURPOSE To investigate the diagnostic effectiveness of dacryoscintigraphy in children with tearing; to evaluate tear clearance rate as a diagnostic factor of dacryoscintigraphy in children with tearing; and to analyze the results of treatment according to dacryoscintigraphic findings in children with tearing. METHODS Between January 2010 and April 2014, 176 eyes of 88 children with tearing (4...

Introduction: The Nasolacrimal duct is the terminal part of nasolacrimal apparatus or tear apparatus. anatomy lateral nasal wall Important for planning surgeries on lacrimal through intranasal approach. Objective: current study was designed to review in relation wall. Material and method: Thirty sagittal sections (14 right 16 left side) head neck formalin fixed adult cadavers known sex, gender,...
