What is the recommended treatment for an oro-antral fistula?

The recommended treatment for an oro-antral fistula is surgical closure. An oro-antral fistula is an abnormal connection between the oral cavity and the maxillary sinus, often resulting from dental procedures, infections, or trauma. Surgery is typically necessary to effectively close the fistula and promote healing, as well as to prevent complications such as chronic sinusitis or further infections.

Surgical closure involves techniques that might include flaps of tissue from surrounding areas to ensure a tight seal and promote healing from both the oral and sinus sides. This intervention is critical to restore normal anatomy and function, thus offering a definitive solution to the problem.

In contrast, antibiotic therapy may help in managing infections but does not address the underlying structural issue. Observation only would not be suitable, as the fistula could lead to complications if left untreated. Bone grafting is often utilized for different purposes, such as in the context of reconstructive surgery after the fistula is closed, rather than as a primary treatment for the fistula itself.
