Closure of Oroantral Fistula

What is oroantral fistula? 

An oroantral fistula is an opening formed between the maxillary sinus and the oral cavity. The cause can be various, including trauma, infection or the result of oral surgery. Treatment of this fistula includes surgical closure.

Surgical methods of closing an oroantral fistula 

It is important to consult with an oral surgeon or an oral and maxillofacial specialist to determine the best treatment for oroantral fistula closure.

There are different surgical methods used to close an oroantral fistula, and the choice depends on the size and location of the fistula. One of the most common methods is so-called flap surgery, which involves taking skin or mucosa from another area of the oral cavity and moving it to the site of the fistula to close it. This surgery may also require additional bone or implant support to ensure that the fistula does not recur.

Surgical closure of an antrooral fistula can be performed using a variety of techniques, depending on the size and location of the fistula. Some of the techniques include:

• Flap technique - this technique involves taking skin or mucosa from another area of ​​the oral cavity, such as the cheek or palate, and moving it to the site of the fistula to close it. The flap is usually placed over the fistula and secured with sutures. This technique is often used to close smaller fistulas.
• Buccal Fat Pad Graft - this is a similar technique to flap surgery, but instead of skin or mucosa, fat tissue from the inside of the cheek is used. This technique is also used to close smaller fistulas.
• Titanium Plate with Transalveolar Wiring - this technique involves placing a bone plate over the fistula to create a physical barrier between the maxillary sinus and the oral cavity. It is usually used to close larger fistulas.
• Endoscopic Repair - this technique involves using an endoscope to examine the maxillary sinus and fistula and placing a fistula closure material from the inside of the sinus. It is usually used to close larger fistulas or if there is a risk of damage to surrounding tissues.
• Combined techniques - in some cases, the surgery may involve a combination of different techniques to achieve the best result

It is important to note that each technique is selected individually for each patient, depending on their specific needs and conditions. The surgeon will discuss with the patient the best option for him/her and explain any risks and complications that may arise.
