Background and Objectives Polylactic-co-glycolic acid (PLGA) plate has been recognizedfor its biocompatibility and biomechanical properties and used widely in various clinicalfields. The aim of this study was to evaluate the usefulness and reliability of PLGA plate as agraft material in septorhinoplasty. Subjects and Method Medical records were retrospectively analyzed for patients who underwentseptorhinoplasty including extracorporeal septoplasty from January 2017 to June 2020. We evaluated demographics, diagnosis, operation techniques, and complications of PLGA plateas a graft material used in these patients. Results A total of 33 patients were enrolled in this study. Twenty-eight were male and 5 werefemale. The median age was 32 years old. The follow-up period after surgery was 6-32 months,and the mean follow-up period was 18.03 months. The PLGA plate was used in unilateralspreader graft (n=17), bilateral spreader graft (n=10), batten graft (n=3), strengthening of septalextension graft (n=2) and columellar strut graft (n=3), and fixing L-strut during extracorporealseptoplasty (n=12). During the follow-up period, no patient experienced extrusion orexposure of the grafts. Mild complications, such as redness of the columella skin, granulationin the marginal incision site, and pain on the nasal dorsum were observed in three patients;these complications were temporary and patients improved with conservative treatments. Conclusion The PLGA plate may be a useful graft material in correcting deviated nose especiallywhen the harvested septal cartilage is insufficient and if used carefully in limited locationssuch as L-strut and columella.
