A Study on Morphometry and Related Surgical Importance of Naso Lacrimal Duct

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, ethnicity present department GMCH, Chandigarh were studied. following parameters made using a digital calliper rounded off nearest millimetres. 1.Length (NLD Length) 2. Nearest distance from maxillary sinus ostium - MSO) 3. NLD anterior spine. (NLD- ANS)4. orifice floor NF) 5. roof. (NSD- NR) 6. attachment Inferior concha. AIT). Observations: In our average length 19.8±1.57mm. observed be located an 24.5±2.6mm spine, ranging 5.5-2. 9mm.The roof found 32.2±1.67mm 16.08±1.71mm floor. addition, inferior concha 14.82±2.37mm. 4.08±0.67mm MSO at level MT. On Comparing side Was slightly longer 22.7 comparison 22.2 mm side. From also larger distances NLD-ANS, NR, -AIT NLD- NF Conclusion: We that most closer done by Ertugel while NLD-NF more specimen.
