Current control of pathogenic bacteria at all biomaterial interfaces is poorly attuned to a broad range of disease-causing pathogens. Leading antimicrobial surface functionalization strategies with antimicrobial peptides (AMPs), Defensins, have...

Objective: This study aims to investigate the clinical effects of the combination of rhytidectomy and temporomandibular joint (TMJ) disc repositioning surgery in internal derangement (ID) stage IV-V and facial aging patients. Methods: Eighteen facial aging with bilateral ID IV-V patients were enrolled in this study. All of them had undergone temporomandibular disc repositioning surgery and rhytidectomy by the same surgeon (Yao Min Zhu). Pre-/post-surgical clinical manifestations, facial photography, radiographic data were recorded and analyzed, as well as doctor, patient, third-party evaluation of postsurgical facial appearance satisfaction. Results: The average age of 18 female patients was 52.9. The average of presurgical visual analog pain scale score was 5.94, ranged from 4 to 8. After 6 months, the average of postsurgical visual analog pain scale score was 0.28, ranged from 0 to 1 (P > 0.05). The average maximal mouth opening of presurgical and postsurgical was 2.19 and 3.29 cm, ranged from 1.2 to 2.8 cm and 3.0 to 3.5 cm, respectively (P < 0.05). Postoperative magnetic resonance imaging showed the location of the bilateral TMJ discs directly above the mandibular condyle. The satisfaction rate of doctors, patients and third-party with facial appearance was 95% to 98%, 96% to 99% and 96% to 99%, respectively, with an average of 95.72%, 98.11%, and 97.50%. Conclusions: For patients with bilateral ID IV-V and facial aging, the combination of disc repositioning surgery and rhytidectomy is a very feasible procedure to treat TMJ disorders and improve patients' facial appearance and satisfaction.
