ABSTRACT
[ABSTRACT]OBJECTIVETo observe the anatomic relationship between the middle and distal section of bony nasolacrimal duct and anterior wall of maxillary sinus. METHODS206 cases of sinus CT without maxillary disorders were enrolled. The middle and distal section of bony nasolacrimal duct and anterior wall of maxillary sinus is divided into fusion type and separation types, and the angle between the anterior and medial wall of the maxillary sinus is divided into frontal and lateral types in relation to the middle and distal section of bony lacrimal duct.RESULTSThe fusion type accounted for 40.05%, and the separate type was 59.95%. There was no statistical difference between male and female.The proportion of inconsistency on both sides was 16.02%. The frontal type of the angle between the anterior and medial wall of the maxillary sinus accounted for 64.08%, meanwhile the proportion of the lateral type was 35.92%. The lateral type was 84.24% out of the cases of fusion type, whereas the frontal type was15.76%. In the separate type, the frontal type accounted for 97.17%, and the lateral type was 2.92%. CONCLUSIONThe anatomic relationship between the middle and distal section of bony nasolacrimal duct and anterior wall of maxillary sinus shows different type, which is helpful to choose operative strategy.
