- Persistent symptoms such as fluid passing into the nose
- A small opening that hasn't closed on its own
- Recurrent sinus infection linked to the opening
A maxillofacial surgeon's evaluation confirms whether this treatment is the right option for you.
What Does This Repair Involve?
This surgery closes the abnormal opening between the mouth and the maxillary sinus using local tissue, restoring normal separation and preventing sinus complications.
Closing the opening promptly, once any acute sinus infection is controlled, gives the best chance of successful healing.

The Care Pathway
1. Assessment & Sinus Treatment
Any active sinus infection is treated before or alongside the repair.
2. Surgical Closure
Local tissue is used to close the opening under local anesthesia.
3. Post-Operative Precautions
Specific precautions, such as avoiding nose-blowing, support healing in the early days.
4. Follow-up
A follow-up visit confirms successful closure and healing.
“Your care team supports you through every stage, from evaluation to recovery and follow-up.”
Expected Benefits and Possible Risks
Surgical closure has a high success rate, effectively resolving the communication and preventing further sinus complications.
Every treatment has potential risks. Your surgeon will discuss your individual risks before treatment.
Recovery & Follow-up
Most patients heal within one to two weeks, with sinus precautions observed during this period.
Your surgeon will provide specific instructions on precautions and confirm complete healing at follow-up.
Careful follow-up and guidance on diet and oral hygiene all play an important role in achieving the best possible outcome.
