Özet
This study aims to develop and demonstrate a new method of creating polymeric vocal cord (VC) models via 3D printing to reduce model production time, increase sound efficiency, and lay the groundwork for future models using more realistic geometric and functional biomaterials. For this purpose, it is to produce a poly (lactic acid) (PLA) based VC implant using a 3D printer as a special design according to the patient's vocal structure. In this study, VC 3D PLA implant (VC3DPLAI), VC stretch piece (measured = 35 mm length), fixed to thyroid cartilage VC (cartilage length = 12 mm) and titanium (Ti64) springs pieces are expected to be produced as a patient-specific implant It is composed of three different biomechanical designs. When you compare this implant with other biomaterials, the VC3DPLAI provides personal convenience compared to complex models and allows unlimited time-cost competition.
Abstract
Vocal cord paralysis (VCP) is considered as a closure of glottal cavity during phonation. Vibration impairment in the vocal mucosa to loss of voice is as a result of the glottic space not closing. Many implant biomaterials are used for VCP. These implants, which can be applied to restore the cord function of the paralyzed cord and to improve the sound quality, are applied in Medialization thyroplasty (MT) type 1 surgeon. The aim of this study is to produce customizable poly (lactic-acid) (PLA) based vocal cord (VC), also called as vocal fold, implant by using 3D printer and compare this implant with other biomaterials. This VC 3D PLA implant (VC3DPLAI) biomaterial can be specially designed and manufactured for the individual.
