Observation on the effect of filling nasal base with connected expanded polytetrafluoroethylene prosthesis through intranasal approach
Objective To explore the clinical efficacy of connected expanded polytetrafluoroethylene prosthesis in improving nasal base depression.Methods From April 2019 to October 2023,a total of 79 patients with poor nasal morphology with nasal base de-pression were retrospectively analyzed.There were 30 cases of primary rhinoplasty and 49 cases of nasal repair.According to the degree of nasal base depression,rhinoplasty was performed and the lacuna was prepared from the nasal column incision and the prosthesis was in-serted.Postoperative complications were observed,patient satisfaction was assessed,and the depression of the nasal base,nasolabial angle,and columnar lobular angle were measured to evaluate the changes.Results All incisions healed by the first intention.One patient had upper lip swelling on the first day after surgery,which disappeared half a month later.One patient had a slightly outward displacement of one nasal base prosthesis in the 7th day after surgery,which was discoverd when removing the 3M tape,and the prosthesis was re-duced after manual extrusion.Seventy-three patients were very satisfied,5 were satisfied and 1 was normal.The depression of the nasal base,nasolabial angle and columnar lobule angle were significantly improved compared with those before operation,with statistical sig-nificance(P＜0.05).Conclusion The application of connected expanded polytetrafluoroethylene prosthesis in nasal reconstruction is effec-tive and of high satisfactionin improving nasal base depression,with fewer complications such as displacement and asymmetry.
