Summary
Brief summary
Rhinoplasty is one of the most common cosmetic surgeries. Lateral osteotomy is one of the surgical methods in rhinoplasty. There are several methods to determine the tear passage time through nasolacrimal duct (NLD) such as dacryocystography, dacryoscintigraphy, Taste test, etc.
One of the useful tests which can be used for determining of tear passage through NLD is dripping of chloramphenicol drop in the eye and recording the passage time by its bitter taste perception by the patient. It should be pointed out that this test is easy to do, inexpensive, accessible, and safe. there is a controversy in the effects of rheinoplasty on naso lacrimal duct system.
In this clinical trial study (before and after intervention), 37 patients (74 eyes) were examined. The chloramphenicol taste test was done one week before and one week, one month, three months, six month after Rhinoplasty. All the results have been statistically analyzed through paired T and other statistic test.
