Comparison of Dorsal Preservation and Dorsal Reduction Rhinoplasty: Analysis of Nasal Patency and Aesthetic Outcomes by Rhinomanometry, NOSE and SCHNOS Scales

Background Dorsal preservation techniques have been preferred and gained popularity in recent years. The current study compares the effects of dorsal preservation and dorsal reduction rhinoplasty on nasal patency and aesthetic outcomes by using Patient-Reported Outcome Measures (PROMs) and rhinomanometry. To our knowledge, this is the first study to compare dorsal preservation and dorsal reduction techniques with rhinomanometry. Methods This is a prospective study of 34 patients who underwent rhinoplasty between January 2021–June 2022. The patients were randomly selected preoperatively and divided into two groups as structural rhinoplasty (SR) and preservation rhinoplasty (PR). Nasal Obstruction and Symptom Evaluation (NOSE), Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS) scales and rhinomanometric evaluation were performed preoperatively, at 3rd month and 12th month postoperatively. Results Nineteen patients (10 female, 9 male) were in SR group, 15 patients (7 female, 8 male) were in PR group. There was not significant difference in terms of age and gender between groups. In both groups, NOSE, SCHNOS-O and SCHNOS-C results were found to be significantly lower at postoperative 3rd and 12th month compared to preoperatively ( p
