A case of maxillary duplication with a soft palate reconstruction using a forearm flap.

Maxillary duplication is a rare congenital anomaly that occurs in the jaw/mouth area. It is generally regarded as sporadic in nature. Total or subtotal soft palate reconstruction for oropharyngeal defects, which include post-surgical and congenital defects, presents a difficult surgical challenge. A maxillary duplication in which the soft palate is reconstructed using a vascularized forearm flap is described. The velopharyngeal insufficiency in the present case is caused by the almost complete deficiency of the soft palate, suggesting that a conventional pharyngeal flap operation with localized mucosal myocutaneous flaps would not produce favorable results in terms of postoperative contractions in the pharyngeal flaps. In such cases, the reconstruction of the soft palate using vascularized free forearm flaps, guided by flexibility regarding the size and adequate thickness of the flaps, may be useful.
