Hi, Your scan report indicates osteomeatal pattern of sinusitis on both sides. This means that there is blockage of the drainage of both your maxillary sinuses following due to which there is development of sinusitis within both maxillary sinuses. The surgery performed would be to relieve this block or to provide an alternate route of drainage for your sinuses. Functional Endoscopic Sinus Surgery (FESS) is often employed to clear the blockage and involves putting a tube in your nose with a camera mounted on it and doing the surgery under direct vision. There are few complications and when performed well, it has a high success rate. The alternative older method is the Caldwell Luc surgery where a small portion of your medial maxillary wall is removed to provide an alternate drainage route. However, sometimes, your symptoms may markedly improve with medications and it would be advisable to consult an ENT surgeon to discuss various options. The deviated nasal septum, hypoplastic turbinate and minimal mucosal thickening in frontal sinus need not be a cause of worry. Sincerely, Vamshi
