Concerning articulation disorders of Moebius syndrome, three cases were analyzed by point of articulation and one case was enforced speech therapy, obtaining following conclusions. 1. Articulation disorders were recognized in bilabials, dentals, alveolars, palatals, velars and / e/ vowel, and appeared in wide ranging points of articulation. This tendency was noticed in two out of three cases. The younger case showed only anterior points of articulation, bilabials and alveolars. 2. In two (cases 1 and 3) out of three cases, the articulation disorders were the most frequently recognized on bilabials, but the other case showed the most disorders in palatals. Therefore, it was suggested that articulation disorders of Moebius syndrome was not always located on the bilabials. 3. In articulation of bilabials, the tongue was seen between upper and lower dentition, and compensated movement between tongue and upper alveolars was observed. By this compensating method, articulation on /p, b, m/ was good, or some distortion for mild disorders was recovered, but /pj, bj, mil were substituted in each alveolars as / pj→tj, bj→t or d, mj→n. 4. But this like compensating method of bilabials was not recognized in the child's case. Therefore, it was thought that this function compenstion was mastered with advancing ages. 5. In the case of the child case, who had been treated only for /p/ sound, showed good result. At the same time, the other bilabials were improved, receiving some good influences from the therapy for /p/ disorder, although the other bilabials were not treated.
