概要	[Objective] Pierre Robin sequence is characterized by retrognathia, which has been reported to lead to a narrow airway. We herein report a case of improvement of retrognathia and narrow airway with orthognathic surgery for mandibular advancement in Pierre Robin sequence. [Results] Following preoperative orthodontic treatment, upper and lower severe crowding was improved. The upper and lower constricted dental arches were expanded, and the dental arch width was coordinated. The mandible was moved forward, and the narrow airway widened after mandibular advancement surgery. The resulting improvements were maintained during a 2-year-1-month retention period. [Discussion and Summary] Orthodontic treatment combined with mandibular advancement surgery improved retrognathia and a narrow airway in a case of Pierre Robin sequence. The airway is considered to have been widened due to mandibular advancement surgery.
