Abstract
To evaluate the clinical efficacy and safety of three-dimensional (3D)-printed patient-specific polyetheretherketone (PEEK) implants for correcting nasal base depression in East Asians, and summarize standardized design principles.
A retrospective study was conducted on 73 patients who underwent 3D-printed PEEK implant augmentation for nasal base depression from May 2024 to May 2025, including 19 cases of isolated alar base augmentation and 54 cases of combined alar-columellar base augmentation. Personalized implants were designed based on preoperative 3D-CT data and fixed with titanium screws intraoperatively. All patients were followed up for 6 months, and implant parameters, operative time, complications, and clinical outcomes were analyzed.
No severe complications such as hematoma, infection, or implant displacement occurred in all patients. Significant correction of nasal base depression was achieved in all cases, with 95.9% of patients reporting complete satisfaction at 6-month follow-up. Key design principles included the lateral border confined within the nasolabial fold, a safety distance of ≥5 mm from the gingiva, and screw holes avoiding dental roots and the maxillary sinus.
Three-dimensional-printed patient-specific PEEK implants are safe, effective, and customizable for correcting nasal base depression in East Asians. Preoperative precise design combined with titanium screw fixation can achieve excellent bony adaptation and high patient satisfaction, serving as a reliable solution for individualized nasal base augmentation.
