How do you close an Oroantral fistula?
The various techniques used to close oroantral fistula include the buccal advancement flap, palatal rotation flap, combination flaps, bone grafts, and buccal fat pad. Occasionally, even a nonsurgical treatment modality like palatal splint is used.
What is oral antral fistula closure?
An oro-antral fistula (OAF) is an epithelialized pathological unnatural communication between oral cavity and maxillary sinus. It develops when the oro-antral communication fails to close spontaneously, remains patent and gets epithelialized. 5. There is migration of oral epithelium into the defect. 1.
What is a primary closure of sinus perforation?
Primary closure of a sinus perforation is indicated for large (≥ 2mm) defects resulting from routine tooth extraction, retrieval of root tips, or implant placement. Bone replacement graft for ridge preservation is indicated to preserve the alveolar ridge needed to support a dental prosthesis.
What is a sinus closure?
A sinus closure is performed when an opening or communication between the mouth and sinus occurs. Sinus closure often heals slowly and with some difficulty. With this procedure light bleeding from the nose is not uncommon for several days after the surgery.
How do you stop OAC?
Preventing an OAC from occurring This involves dividing the tooth roots , and possibly removing a little of the bone surrounding the roots. This preserves more of the bone which forms the sinus floor than extracting the tooth as a whole.
How do you identify an oral antral fistula?
Diagnosis
- Valsalva test (nose blowing test): Ask the patient to pinch the nostrils together and open the mouth, then blow gently through the nose.
- Perform a complete extra- and intra-oral examination using a dental mirror under good lighting, look for granulation tissue in the socket and openings into the antrum.
How is Oroantral fistula diagnosed?
The establishment of oroantral communication can be confirmed by the Valsalva method. The patient is instructed to expel air against closed nostrils, while the clinician checks if air hisses from the fistula into the mouth. A hissing noise from air leakage through the maxillary sinus and nose indicates a positive test.
What is PRF in dentistry?
Platelet-rich fibrin (PRF) is an autologous platelet concentrate prepared from the patient’s own blood at the dentist’s office just before the oral/dental procedure.
How is a sinus closure done?

Primary Closure of a Sinus Perforation Primary closure of a sinus perforation is indicated for large (≥ 2mm) defects resulting from routine tooth extraction, retrieval of root tips, or implant placement.
