Sinus problems are common, and often can be treated with medicines, nasal sprays or other non-surgical methods. However, surgery may be needed for those with chronic sinusitis, nasal polyps, recurrent infections, blocked sinus openings or structural problems in the nose. In India, experienced ENT (ear, nose and throat) specialists perform sinus surgery with modern techniques such as Functional Endoscopic Sinus Surgery (FESS).India has well developed hospitals, skilled ENT doctors, modern diagnostic facilities and relatively affordable cost of treatment. The cost will vary depending on the type of surgery, hospital, surgeon's experience, city, any diagnostic tests and if additional procedures such as septoplasty or turbinate reduction are required.
