Characteristics of Intranasal Structures for Endonasal Dacryocystorhinostomy in Asians

The uncinate process, operculum of the middle turbinate, and agger nasi cell should be removed for sufficient osteotomy in a significant portion of Asian patients during dacryocystorhinostomy. A thick frontal process of the maxilla can be anticipated for the patient with a low nasal bridge. Further studies on the variation in intranasal procedures and the success rate of endonasal dacryocystorhinostomy need to be established.
