PURPOSE: To evaluate whether the use of a direct otoscope in the nose is an effective method to observe the nasolacrimal anastomosis site after dacryocystorhinostomy.
METHODS: In 75 eyes undergoing external dacryocystorhinostomy, the lacrimal irrigation test was performed and fluorescein solution was instilled in the conjunctival sac. After applying topical anesthetics and decongestant, a direct otoscope was inserted in the middle meatus and directed toward the medial canthus.
RESULTS: In 69 eyes (92%), intranasal lacrimal examination with the otoscope could be performed. In 6 eyes (8%), the otoscope could not be adequately advanced in the nose because of middle meatal stenosis (n = 5 eyes) or intolerance to the intranasal examination (n = 1). In 66 (96%) of 69 eyes, concordant with the results of the lacrimal irrigation test, the presence or absence of fluorescein dye flow in the nose was observed. In this examination, the main features that were useful in locating the anastomotic area were (1) the use of fluorescein dye, (2) motility of the nasal mucosa that was synchronized with eyelid movements, (3) appearance of mucosal hole or internal orifice in the nasal wall, and (4) dye or air-fluid bubble emergence upon blinking or finger pressure over the sac region.
CONCLUSIONS: Direct otoscope can be effectively used in the nose for examining the nasolacrimal anastomosis in patients undergoing dacryocystorhinostomy.
