Closure of Abnormal Openings Between the Mouth and Sinus or Nose
An oroantral or oronasal communication is an abnormal opening between the mouth and either the maxillary sinus (oroantral) or the nasal cavity (oronasal).
These can occur following trauma or surgery, and may lead to persistent symptoms if not repaired appropriately.
The aim of treatment is to restore separation between the oral and nasal/sinus cavities, allowing normal healing and function.
Symptoms
Symptoms may include:
- Fluid passing from the mouth into the nose
- Altered sensation when drinking
- Air escape through the nose when speaking
- Persistent sinus symptoms (e.g. infection, discharge)
- Bad taste in the mouth
Small communications may initially be subtle but can persist without treatment.
When Treatment Is Required
Management depends on size and duration.
- Small, recent openings may close spontaneously with conservative measures
- Larger or persistent defects usually require surgical repair
The Procedure
Repair is typically performed under general anaesthetic.
- The defect is carefully exposed
- Any infected or non-viable tissue is removed
- A flap or closure technique is performed
- The site is closed to achieve a watertight seal
The procedure is planned to minimise tension and maximise healing.
Postoperative Care
Care following repair is critical.
Patients are advised to:
- Avoid nose blowing
- Avoid forceful sneezing (or sneeze with mouth open)
- Follow a soft diet initially
- Wear a cover plate
- Maintain careful oral hygiene
These measures help protect the repair during early healing.
Recovery
- Mild discomfort and swelling are expected
- Healing generally progresses over several weeks
- Sutures are removed or dissolve depending on the technique
Follow-up ensures the closure remains intact.
Risks and Considerations
Potential risks include:
- Breakdown of the repair
- Recurrence of the communication
- Infection (particularly sinus-related)
- Need for further surgery in complex cases
Careful technique and postoperative management reduce these risks.
When to Seek Assessment
You should seek assessment if you experience:
- Fluid passing between mouth and nose
- Persistent symptoms following upper tooth extraction
- Signs of sinus involvement
Early assessment allows simpler and more predictable treatment.
Consultation
A consultation allows confirmation of the diagnosis and planning of appropriate repair.
