Analysis of the use of isotretinoin as an adjuvant in rhinoplasty.

Background: Isotretinoin has been used in the treatment of acne for decades through the reduction of sebaceous secretion. There are reports in the literature that isotretinoin may be associated with decreased skin thickness, especially in patients with thick nasal skin for whom rhinoplasty can be more challenging. The objective of this study was to quantify, through ultrasonography, the effect of the use of oral isotretinoin in patients undergoing rhinoplasty, pre- and postoperatively.
