Background: Porous high-density polyethylene implants (Medpor®) have been extensively used for septal extension grafts in Asian rhinoplasty. However, studies on the long-term complications associated with Medpor® have not been reported. Therefore, the purpose of this study was to evaluate the long-term complications of septal extension grafts using Medpor® and present a reconstructive strategy for destructed septal L-struts. Methods: We conducted a 12-year retrospective medical chart review of 428 patients who visited our center for septorhinoplasty. Among 428 patients, 43 patients had Medpor® for septal extension grafts previously applied at other clinics. The quadrangular cartilage was devoid or destructed in the area where Medpor® was previously applied. Therefore, all patients underwent secondary septorhinoplasty using autogenous cartilage grafts. Patient outcome was assessed to evaluate satisfaction, hardness of nasal tip, functional nasal obstruction symptom evaluation (NOSE) scores, and pain scores. Anthropometric analyses were carried out with patients’ photographs. Postoperative complications were also evaluated. Results: After septal L-strut reconstruction, 87% of patients were satisfied with their aesthetic results. Hardness of nasal tip, NOSE scores, and pain scores also improved after reconstruction. Anthropometric analyses demonstrated that increased nasal length and decreased columellar–labial angle were achieved in patients with short nose deformities. No postoperative complications related to the reconstruction were recorded for any patient. Conclusions: The devastated destruction of nasal support lines was found after the use of Medpor® for septorhinoplasty. Therefore, the use of Medpor® should be reduced. Autogenous cartilage grafts are the last resort for reconstruction of destructed septal L-struts. Level of Evidence IV: This journal requires that authors assign a level of evidence to each article.
