14.4 3D PRINTING OF PERSONALIZED SILICONE IMPLANT 277

FIG. 14.4 (A) Inflammatory granuloma of the vocal fold in laryngoscopy. Endoscopic views of the three types of benign tracheal stenosis:
(B) simple stenosis in diaphragm. (C) and (D) are complex stenoses. (E) Posttracheostomy stenosis in “B.” Tumor stenosis: (F) squamous cell carcinoma
of the trachea. (G) Adenoid cystic carcinoma of the trachea. Pictures (A), (F), and (G) were kindly provided by the University of Reims. (Reprinted with

these diseases. These implants are manufactured using injection molding technique, and we will demonstrate the lim-
itations of this technique from the point of view of implant personalization.
a. Laryngeal level

There are generally two types of laryngeal prostheses used to treat these diseases, Fig. 14.6A–C. The most estab-
lished implant is the Montgomery “T” tube. It is used for multidilated laryngeal stenosis and for postoperative cali-
bration. The anterior horizontal part allows breathing during the pose in the same way as a tracheotomy tube.
