Abstract:
Objective:To investigate the effect of ship-shaped expanded polytetrafluoroethylene (e-PTFE) nasal prosthesis in rhinoplasty.Methods:From February 2016 to June 2021, 86 patients, including 9 males and 77 females, aged 18-47 (24±5) years old, were admitted to Chengdu High-tech Zone Xinyuerong Medical Aesthetic Clinic for cosmetic treatment of rhinoplasty. All patients underwent rhinoplasty with the application of ship-shaped e-PTFE and autologous cartilage. The postoperative complications, glabellar fullness, inverted brow triangle, nasal polygon aesthetic shape and patient satisfaction were evaluated. These data were measured and analyzed, including the nasal length, nasal tip height, nasal frontal angle and nasal facial angle before and after the operation.Results:In 86 patients, the incision healed in one stage after surgery, and 8 cases had nasal vestibular scar hyperplasia. All patients were followed up for 1-5 years: 84 cases obtained satisfactory nasal morphology, and 2 cases recovered naturally after adjusting and lowering the prosthesis height half a year after surgery because the interbrow area was too full. 74 patients (86%) were very satisfied, 10 cases (11.6%) were satisfied. The nasal length was (4.07±0.20) cm, the nasal tip height was (2.66±0.36) cm, the nasal frontal angle was (106.42±8.04)°, and the nasal face angle was (15.90±0.85)°before operation. The nasal length was (4.23±0.20) cm, the nasal tip height was (2.59±0.26) cm, the naso-frontal angle was (113.69±6.34)°, and the naso-facial angle was (21.57±0.78)° at eighteen months after operation. There were statistically significant differences in nasal length, naso-frontal angle and naso-facial angle ( t=-5.51, -5.96, -52.31, P<0.01), but no statistically significant differences in nasal tip height ( t=1.47, P=0.146). Conclusions:The ship-shaped e-PTFE can be shaped to reflect the aesthetic of the nose dorsum, which is similar to the anatomical structure of the nose dorsum, increase the stability and authenticity of the prosthesis, and is worthy of clinical application.
