Efficacy of closed reduction of nasal fractures-a retrospective analysis with focus on factors affecting functional and aesthetic outcomes.

[BACKGROUND] Nasal bone fractures are the most common type of facial bone fractures. While the nasal anatomy and closed reduction techniques of nasal fractures are well described, there is a paucity of data reporting on the need for revision rhinoplasty. The objective of this study is to analyze the factors affecting the outcome and need for revision rhinoplasty in patients who underwent closed reduction for nasal bone fracture.

[METHODS] From 2010 to 2020, a total of 417 consecutive patients underwent closed nasal reduction. Medical files of the patients were reviewed retrospectively. The rate of rhinoplasty after fracture consolidation was determined. Factors influencing the need for revision rhinoplasty were assessed using univariable and multivariable logistic regression analyses.

[RESULTS] Forty-seven patients (11.3%) required revision rhinoplasty after fracture healing. Patients who had suffered an additional septum fracture were more likely to undergo rhinoplasty. The risk of the need for open revision rhinoplasty after fracture healing was increased for patients complaining of airway obstruction at the time of cast removal after closed reduction.

[CONCLUSION] A certain number of patients will require secondary revision rhinoplasty after closed reduction of a nasal fracture. Subjective airway obstruction at the time of cast removal after closed reduction is a predictor for revision rhinoplasty. Prospective studies are required to support the findings of this investigation.
