How do you manage OAC?

How do you manage OAC?

OAC/OAF should be managed promptly by creating a barrier between oral cavity and maxillary sinus to prevent maxillary sinusitis. Treatment modalities to repair the oro-antral defects include local or free soft tissue flaps, with or without autografts or alloplastic materials.

How long does it take for a sinus communication to heal?

Sinus communication: A sinus communication occurs when a very small hole is made in your sinus lining. Sinus communications are the most commonly experienced side effect of a root canal. These holes are so small they often heal on their own, taking about 2-3 days to fully heal before you are symptom-free.

How can Oroantral fistula be prevented?

Avoid using too much of apical pressure during tooth extraction. Perform surgical extraction with roots sectioning.

What is OAC dental?

An oroantral communication (OAC) is an unnatural space that forms between the maxillary sinus and oral cavity following extraction of antral teeth, infection, or several different complications. If left untreated, an OAC can develop into an oroantral fistula (OAF) or chronic sinus disease.

What is oroantral communication?

Introduction Oroantral communication (OAC) is a gap between the maxillary sinus and the oral cavity. When left untreated, it can lead to an oroantral fistula and maxillary sinusitis [1]. Oroantral communications are often iatrogenic following the extraction of antral or sinus teeth.

How long does it take for oroantral communication to cause sinusitis?

Indeed, in the face of extensive untreated oroantral communication, 50% of patients develop sinusitis after 48 hours and 90% after two weeks with a filling of the sinus on radiological examination [3] (Figure 2). In the healthy sinus, OACs less than 5 mm close spontaneously [4].

What are oro-antral communications and fistulas?

Oro-antral communications and fistulas (OACs & OAFs) are complications frequently encountered by oral and maxillofacial surgeons. Oro-antral communication is an unnatural communication between the oral cavity and the maxillary sinus. These complications occur most commonly during extraction of upper molar and premolar teeth (48%).

How long does oroantral communication take to develop?

Material and methods TERMINOLOGY The term oroantral communication comprises two pathologic conditions. One is the acute oroantral perforation and the other is the chro- nic communication (fistula). Szano~4 found 7-8 days to be the average time for an oro- antral perforation to epithelialize and become a chronic fistulous tract.
