Topical Tretinoin in the Management of Thick-skinned Rhinoplasty Patients.

[BACKGROUND] Despite the increasing popularity of cosmetic surgeries, some patients still experience skin problems, particularly those with thick nasal skin. Isotretinoin is a commonly used drug for severe acne, and its effects on rhinoplasty aesthetic results have recently been studied. This placebo-controlled clinical trial aimed to investigate the effects of topical tretinoin gel on the cosmetic outcomes of rhinoplasty in patients with thick nasal skin.

[METHODS] Forty-nine individuals were randomly allocated to either the treatment group or the control group in Mashhad, Iran from 2019 to 2021. The treatment group received topical tretinoin gel (0.05%) beginning on the 31st postoperative day and continued for six months, while the control group received a usual dermatological recommendation as a placebo. Patients were assessed during the first, third, and sixth months after the intervention, and their cosmetic results were evaluated by an expert surgeon and dermatologist.

[RESULTS] There were no significant differences in baseline features between the two groups. The median score given by the surgeon was not significantly different between the groups. However, the median score given by the dermatologist was significantly higher in the treatment group during the first, third, and sixth months (<0.001). Patient satisfaction scores were also significantly higher in the treatment group during the third and sixth months compared to the control group. (=0.02 and 0.01, respectively).

[CONCLUSION] Topical tretinoin gel could effectively reduce acne in patients with thick nasal skin after rhinoplasty and increase patient satisfaction in the early months following surgery. However, it did not significantly affect final cosmetic outcomes.
