Abstract:
Objective:To investigate subalar change after rhinoplasty with costal cartilage.Methods:A retrospective study was performed on patients who received cartilaginous rhinoplasty at the Rhinoplasty Center of Plastic Surgery Hospital, Chinese Academy of Medical Sciences from May 2019 to August 2020. The facial three-dimensional(3D) and CT scanning data of young female cases was analyzed. Pre-operative and more than 6 months follow-up data was matched. The 3D facial coordinate system was established. Preoperative and postoperative location of the subnasale and the lateral point of nasal-facial junction, the angle between endocanthion-alare and coronal plane and the nasolabial angle were analyzed with paired samples t-test. The volume of subalar area was analyzed with one-sample t-test. Results:Eighteen female cases aged (27.30±4.41) years were enrolled in the study with (10.61±3.53) months follow-up. One case (5.6%) suffered from nostril asymmetry one month after the surgery. The subnasale moved forward from (74.30±1.97) mm to (77.67±2.37) mm [average difference (3.36±0.96) mm]. The lateral point of nasal-facial junction moved forward from (65.51±2.45) mm to (68.05±2.52) mm [average difference (2.53±1.50) mm]. Nasolabial angle was (88.79±11.21) degree preoperatively and (101.37±5.53) degree postoperatively [average difference (12.57±7.57) degree]. Angle between endocanthion-alare and coronal plane increased from (9.01±3.24) degree to (12.73±3.27) degree [average difference (3.72±2.22) degree]. The differences between pre- and post-operative data were statistically significant ( P<0.01). The volume of subalar area increased by (282.59±103.22) mm 3. The difference was statistically significant ( P<0.01). Conclusions:Rhinoplasty with costal cartilage could make subalar area move forward.
