Introduction:
The autologous conchal cartilage of good elasticity is easy to harvest, thus is often used in nasal tip plasty of East Asians. However, the operation techniques vary a lot among different surgeons. This article aims to introduce 3 techniques commonly used in clinical practice.
Methods:
One hundred three patients were included in this study and divided into 3 groups according to the shape of the nasal tip during 2017 to 2019. The patients were followed up for at least 6 months. All patients were measured with Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS). ImageJ software was used to measure and calculate the projection ratio for lateral position standard image, and columella-labial angle (CLA) was measured.
Results:
In group 1, SCHNOS for nasal obstruction (SCHNOS-O) score were 13.23 ± 7.61 and 14.49 ± 10.55 (P > 0.05); SCHNOS for nasal cosmesis (SCHNOS-C) score were 66.55 ± 31.23 and 21.73 ± 18.91 (P < 0.001); projection ratio were 0.51 ± 0.04 and 0.57 ± 0.05 (P < 0.001); CLA were 91.02° ± 5.67° and 93.55° ± 4.64° (P > 0.05), preoperative and postoperative, respectively. In group 2, SCHNOS-O score were 16.76 ± 13.44 and 15.44 ± 9.26 (P > 0.05); SCHNOS-C score were 61.87 ± 44.14 and 19.16 ± 29.37 (P < 0.001); projection ratio were 0.50 ± 0.05 and 0.58 ± 0.03 (P < 0.001); CLA were 92.32° ± 6.39° and 94.86° ± 5.96°(P > 0.05), preoperative and postoperative, respectively. In group 3, SCHNOS-O score were 15.25 ± 7.83 and 17.73 ± 11.66 (P > 0.05); SCHNOS-C score were 52.03 ± 33.38 and 17.73 ± 11.66 (P < 0.001); projection ratio were 0.53 ± 0.05 and 0.57 ± 0.02 (P < 0.001); CLA were 91.65° ± 5.75° and 93.21° ± 5.38° (P > 0.05), preoperational and postoperational, respectively.
Conclusions:
None of these 3 techniques cause or aggravate nasal obstruction, and all of them can achieve high cosmetic satisfaction. Technique 1 and technique 2 are suitable for the patients with moderate and moderate to severe short nose that is common in East Asia, which can better increase the protrusion of the tip and length of the nose. Technique 3 is suitable for the patients with better shape of the nose, who need to slightly increase the protrusion of the nasal tip and increase the upward rotation.
