Nasal Deviation and Facial Asymmetry in Patients Undergoing Rhinoplasty.

Background: The existing literature is conflicted on whether nasal deviation is primarily attributable to trauma or the result of asymmetric facial development.

Objectives: The aim of this study was to establish the prevalence of nasal trauma and facial asymmetry in patients undergoing rhinoplasty, and to determine if a correlation exists between the laterality of facial asymmetry and nasal deviation.

Methods: A retrospective review was undertaken of patients who had undergone primary rhinoplasty with the senior author over a 12-month period. Patient charts were reviewed and clinical photographs were analyzed.

Results: In total, 144 patients underwent rhinoplasty over the study period; 68 patients underwent revision rhinoplasty and were excluded. Of the 76 patients who underwent primary rhinoplasty, 9% reported prior nasal trauma, 68% had deviated nasal bones, 46% had deviated nasal tips, 70% had asymmetric midfaces, and 36% had deviated chins. In patients without prior trauma history, nasal bones were most commonly deviated towards the side of midface hypoplasia (53%, P = .008). The nasal tip was most commonly deviated contralateral to the side of septal deviation (59%, P = .001). There was no association between nasal bone and chin deviation. Nasal tip deviation was not associated with midface hypoplasia or chin deviation.

Conclusions: Nasal deviation is primarily driven by asymmetric facial growth rather than being the result of nasal trauma.
