When utilizing a tongue flap to close an alveolar cleft defect, the typical flap orientation is anterior based. This choice is grounded in the anatomical and functional characteristics of the tongue and the surgical objectives involved in repairing the cleft.

An anterior-based flap allows for adequate blood supply, as the vascularity of the tongue is best at the anterior aspect, stemming from the lingual artery. This orientation also ensures that the flap can be rotated into the defect with minimal tension, promoting better healing and reducing the risk of flap necrosis. Additionally, it facilitates optimal alignment of the mucosal tissues, which is crucial for functional and aesthetic outcomes in the orofacial region.

The goal of using a tongue flap in this manner is to achieve a well-vascularized area of tissue that can effectively cover the alveolar cleft, promoting successful integration and functioning of the surrounding structures. Given these points, the anterior-based orientation is well supported clinically and aligns with best practices in oral and maxillofacial surgery for managing such defects.
