Sinus surgery may be indicated when significant sinusitis symptoms persist despite appropriate treatment with medications. Before surgery is recommended, a CT scan of the sinuses will be recommended in order to better understand the causes of the patients symptoms and the extent of sinus disease present. Most commonly, sinus surgery can be performed with the aid of endoscopes, which will allow for a clear view inside the nose without the need for incisions on the face. Balloon Sinuplasty may be recommended for certain types of sinus conditions. This technique involves the use of specialized balloons to widen the opening into the sinuses in order to improve sinus function. Not every type of sinus condition is amenable to Balloon Sinuplasty techniques as a treatment. Suitability is determined after a complete evaluation.
