Abstract:
Objective:To investigate the clinical effect of "mutual support" framework in costal cartilage rhinoplasty.Methods:From June 2020 to December 2021, the patients were enrolled and undergone rhinoplasty with bilateral lower lateral cartilage margin incision combined with nasal columnar incision in the Department of Plastic & Reconstructive Surgery of Zhejiang Provincial People’s Hospital. During the operation, the sixth costal cartilage was made into the nasal columella support graft(strut) and the nasal tip graft integrated scaffold, and the septal extension grafts (SEG). The strut and SEG were sutured in the same plane to construct the framework to correct the aesthetic defects of the nose. Abode Photoshop CS 6.0 was used to measure a series of aesthetics index before and 6 months after surgery, including nasofrontal angle, nasorostral angle, nasolabial angle, columella lobular angle, ratio of tip projection to the length of the nose and ratio of the length of the infratip lobule to the length of the nasal columella to evaluate the surgical effect. Visual analogue scale (VAS) and rhinoplasty outcome evaluation (ROE) were used to investigate the patients’ satisfaction. Paired t-test was used for data analysis and P<0.05 was considered statistically significant. Results:A total of 53 patients were enrolled, including 4 males and 49 females, aged from 18 to 45 years (average age: 25.6 years). Forty-nine cases were primary rhinoplasty and 4 cases were secondary rhinoplasty. No short-term complications including hemorrhage and infection occurred in 53 patients. All patients were followed up for 6-12 months. There were statistically significant differences in nasofrontal angle, nasorostral angle, nasolabial angle, columella lobular angle, ratio of tip projection to the length of the nose and ratio of the length of the infratip lobule to the length of the nasal columella( P<0.01), which sugguested that aesthetic defects of the nose were corrected and no obvious deflection and rotation of nasal tip occured. VAS score and ROE score postoperatively were 7.6±0.4 and 21.3±2.1, respectively, which were significantly higher than preoperatively( 6.1±0.5, 10.5±1.6)( P< 0.01). Postoperative satisfaction survey showed that swelling disappeared within 4-6 weeks after surgery, and no obvious ventilatory disorder, paresthesia and hyposmia symptoms occurred. Most patients were satisfied with the aesthetic and functional results. Conclusions:The "mutual support" framework in costal cartilage rhinoplasty can reduce the risk of framework deflection and nasal tip rotation and obtain satisfactory nasal columella shape.
