Dear DoctorI am Sabu, 27/male from Kerala. I had a right side molar tooth extraction 3 years ago and then I had recurrent sinusitis. I felt pus coming out of my nostrils and got bad smell of the pus. When that happened I took some antibiotics and it was subsided. It happened a  couple of times. Then in January 2010(after 2 yrs of extraction) I had the pus formation and bad smell and I met an ENT. They took scanning and some other tests and told me that I have to undergo FESS. So I underwent FESS in February. After 35 days of FESS, I had the pus formation again and that time I consulted an Oro Maxilo Facial surgeon . he did many x rays and found out that there is an Oro Antral fistula , which was the cause of the recurrent infection and PUS formation. So I had to undergo cod wel luc surgery and they close the fistula by flap. After 5 months of the surgery now, I again felt some pain over the flap and some blockage of nose. But this time I did not feel pus or bad smell. What comes out of nose is clear mucous. I again met the doctor and he told me that the pain is because of the inflammation on the top layer of flap due to the common sinusitis. He gave me augmentin 625 mg for 5 days. I am worried if the infection will become any serious trouble in future. Should I undergo any checkups again, or to take any medicines? IS the sinusitis I feel now is common?? Will it affect the flap adversely? Please let  me know as early as possible.Thanks doctor.

Thanks for using Chat Doctor. Read your query. Yes, An oro-antral communication is a potential complication of an upper molar extraction. Since you have already undergone a successful closure operation, the mucus discharge should be of a regular sinusitis. If it is persistent and is getting infected regularly, please visit your oral and maxillofacial surgeon and have the astral communication status reviewed. Continue with the antibiotics and medication for sinusitis as prescribed. Hope this was helpful. Thanks and regards
