In a lip-switch vestibuloplasty, the mucosal flap sutures are typically placed to the cut periosteal edge at the depth of the vestibule. This technique involves creating a flap of mucosa, which is then repositioned to extend the vestibule.

Placing the sutures at the periosteal edge ensures proper anchorage and stability of the flap, facilitating optimal healing and maintaining the new vestibular depth. This method enhances the functional and aesthetic outcome by preserving the mucosal integrity and ensuring that the soft tissue aligns well with the underlying bone, allowing for better adaptation and reduced tension on the flap.

The positioning of sutures at the depth of the vestibule plays a critical role in re-establishing the anatomical and functional relationships in the area, which can be beneficial in preventing complications like flap necrosis or inadequate vestibular depth.
