Porous high-density polyethylene (pHDPE) is an alternative material for septal extension grafts. This study investigated the clinical application of a single T-shaped pHDPE graft combined with auricular cartilage in oriental nasal tip-plasty. A retrospective analysis was conducted of 66 patients who underwent septal extension graft with a T-shaped pHDPE and auricular cartilage graft from December 2018 to November 2021. All patients were female from 19 to 51 years old (average: 28.9 years). Patients were followed up for 5 to 40 months with an average of 23.8 months. The postoperative nasal length (39.8±3.7 mm) was significantly improved (35.6±5.7 mm preoperatively, P <0.0001) with the tip projection increasing from 23.9±2.3 mm preoperatively to 25.3±2.4 mm postoperatively ( P =0.0005). There was a significant difference in the nasolabial angle (96.8±14.1 degrees preoperatively versus 101.8±7.2 degrees postoperatively, P =0.0105) but no significant change in the nasofrontal angle (143.3±9.5 degrees preoperatively versus 143.7±5.5 degrees postoperatively, P =0.7546), with an improved tip projection achieved in 93.9% of patients. One patient had an abscess in the nasal septum and a tip graft was performed using auricular cartilage in another patient because of an insufficient postoperative tip projection. There was a slight tip deviation in 2 patients, 1 case of a deviated nasal tip was corrected with a pHDPE sheet graft, while the other was left intact. Two patients had excess cartilaginous graft protruding to the nasal cavity that did not affect nasal ventilation and the shape of the nasal tip was relatively good, so the prominent cartilaginous graft was not addressed. In conclusion, this technique not only improved the bulbous nasal tip, lengthened the short nose, and increase the tip projection, but also prevented absorption of the existing septal cartilage and reduced infection or extrusion of the pHDPE.
