What is the most critical factor for success in a submucosal vestibuloplasty?

In the context of a submucosal vestibuloplasty, the most critical factor for success is the careful management of the stent placement and its duration. Leaving the stent for an extended period allows for adequate healing of the tissues involved and helps maintain the created vestibule, thereby preventing fibrosis or contraction that could hinder the surgical outcome.

The purpose of the stent is to provide a barrier that prevents the vestibular tissue from collapsing during the healing phase. If the stent is removed too soon, there is a risk that the newly formed tissue may not be sufficient to maintain the vestibular depth necessary for functional and aesthetic outcomes.

A stent that is left in place for an appropriate duration ensures that the tissues have sufficient time to adapt and heal in their new position, which is essential for the long-term success of the procedure. Successful vestibuloplasty not only relies on creating the vestibule but also on ensuring that it remains open and functional post-operatively.
