Q:
What is oroantral fistula?
A:
Oroantral fistula (OAF) is an abnormal condition that manifests a pathological communication between the maxillary sinus and the oral cavity.
Cause
OAF mostly results from insufficient knowledge and preparation before dental procedures such as extraction of the teeth.
Symptoms
- Fluid going from mouth to nose when drinking;
- A sensation of air rushing through the socket while breathing;
- Feeling painful when secondary sinusitis develops.
Diagnosis
You can take following tests to diagnose the condition:
- Extraoral and intraoral examination;
- Patency of communication test (rinsing the mouth);
- Valsalva test (nose blowing test);
- Cotton wisp test;
- Mouth mirror test;
- Gentle suctioning test (check for hollow sound)
Treatments
Your doctor may first estimate your fistula diameter. Estimation results can provide the foundation for your treatment planning, including:
- Drug therapy;
- Surgical procedure.
If you have any questions, please go to see a doctor for professional help.
