A soft palate support having a layered structure (3) for treating sleep apnea syndrome or snoring and an implanting method. The soft palate support having a layered structure (3) is a flat implant made of a material capable of being implanted into a human body for a long time, and comprises a hard palate connecting end (1) and a supporting body (2). The supporting body (2) is a layered structure capable of being inserted into a soft palate (7) and is formed from two or more than two layers of supporting boards (21) superposed. The supporting body (2) is fixed to the hard palate connecting end (1) removably or non-removably. A connecting structure (11) connected with the hard palate (6) is disposed on the hard palate connecting end (1). The hard palate connecting end (1) is fixed to the hard palate (6) by the connecting structure (11). The supporting body (2) is implanted into muscular layers of the soft palate (7), the supporting body (2) being inserted into the soft palate (7) by a length equal to 1/5 to 4/5 of the total length of the soft palate (7). The layered structure formed by the superposed supporting boards (21) ensures the supporting force, enhances the compliance of the supporting body (2), and substantially improves the fatigue life of the supporting body (2).La présente invention concerne un support (3) pour palais mou ayant une structure stratifiée destiné au traitement du syndrome de l'apnée du sommeil ou des ronflements, ainsi qu'un procédé d'implantation associé, le support (3) pour palais mou à structure stratifiée étant un implant plat constitué d'un matériau pouvant être implanté dans un corps humain pour une longue durée et comprenant une extrémité de connexion (1) au palais dur et un corps de support (2) qui est une structure stratifiée pouvant être insérée dans le palais mou (7) et formée par deux couches ou plus de plaques de support (21). Le corps de support (2) est fixé à l'extrémité de connexion (1) au palais dur de manière amovible ou ina
