Background and Objective: The ability to predict the impact of different rhinoplasty methods on the changes made in facial components is important. The aim of this study was to predict the possible changes in the upper lip following the cutting of the depressor septi nasi muscle in rhinoplasty in order to choose the appropriate treatment plan (a suitable choice).
Methods: In this cross-sectional study, 22 candidates for rhinoplasty who were operated on in private hospitals and clinics in Babol city in 2023 were examined for changes in the upper lip after cutting the depressor muscle septi nasi muscle in rhinoplasty. The size of the length of the upper lip (from the columella area to the upper edge of the vermilion of the upper lip), vermilion view (from the upper edge of the vermilion to the lower teeth of the upper lip) and anterior teeth (the lower edge of the vermilion to the lower edge of the incisors of the middle incisors of the upper jaw) and the gum view ( from the lower vermilion edge of the upper lip to the gingival zenith of the maxillary central incisors) between the time intervals before surgery, 14 days, 1 and 3 months after surgery were compared by using repeated measurements and paired samples t-tests. A significant level of 0.05 was considered.
Findings: The average length of the upper lip before surgery was 17.82±3.05 mm, which significantly increased 3 months after surgery to 20.77±3.22 mm (p<0.001). The average vermilion display also increased significantly from 6.50±2.12 before surgery to 7.44±2.30 mm 3 months after surgery (p<0.001). The average display of anterior teeth 3 months after surgery was 2.14±1.13 compared to before surgery by 2.58±1.43 mm (p<0.001).
Conclusion: According to the results, cutting the depressor muscle of the nasal septum causes an increase in the length of the upper lip and the display of vermilion, and a decrease in the display of the anterior teeth in the state of rest and the gums in the state of smiling. Therefore, smile analysis is recommended for every person before performing rhinoplasty.
