[|Human|] a 6 months pregnant woman had her upper right first molar extracted because it was crossly carious. unfortunately after 3 weekis shes experiencing water coming out of her nose, as well as wind coming out of the unhealed socket. if it is oroantral fistula, what can we do about it?
[|AI|]  Thanks for using Chat Doctor. Read your query. Signs and symptoms suggests the creation of an frontal fistula, which should be of some concern. Oroantral fistula closure is very important to avoid food and saliva contamination that could lead to bacterial infection, impaired healing and chronic sinusitis. The treatment is done taken in consideration the width, epithelialization and presence or absence of infections. I would advise that is the fistula is less than 3 mm, it usually heals spontaneously in the absence of any infections. If in your case the defect is more than this, it will require further treatment using flaps which will be best decided by your surgeon. Please consult your surgeon and have it reviewed. Hope this was helpful. Thanks and regards.
