Abstract
This clinical report describes the management of a patient who was diagnosed with amniotic band sequence (ABS) complicated with severe skeletal malocclusion, associated with severe muscle weakness. The patient was a 23-year-old male who underwent treatment in our hospital to improve chewing, phonation, and swallowing difficulties caused by severe abnormality of the maxillofacial skeleton. We evaluated chewing, swallowing and language functions preoperatively, and started muscle function and oral rehabilitation therapy. We performed 2-jaw osteotomy after preoperative orthodontic treatment. The patient continued with postoperative orthodontic treatment and oral rehabilitation. Postoperatively, the patient showed improved maxillofacial morphology, but was unable to attain sufficient improvement of masticatory and language functions due to atrophy and poor development of the masticatory muscles. These results suggest that obtaining sufficient therapeutic effect on oral functions is not possible if the masticatory muscles are not sufficiently strong due to atrophy or hypoplasia.

Summary
Amniotic band sequence (ABS) is caused by rupture of the amniotic membrane in the early embryonic stage,. (2015) A Case of Amniotic Band Sequence Complicated by Severe Skeletal Malocclusion. This syndrome is sporadic, reportedly occurring in approximately 1 in 12,000 15,000 live births [3]. We encountered a case of ABS in which the patient exhibited severe skeletal dysfunction associated with muscle weakness. To the best of our knowledge, this represents the first case of ABS described in the literature characterized by severe skeletal malocclusion and managed by 2-jaw osteotomy with pre- and postoperative functional evaluations
