Lugol cautery is a treatment used for sinus pain and drainage. The procedure uses multiple nasal sprays to superficially cauterize (burn) the nasal passages. This procedure is very helpful in controlling a chronic runny nose, bothersome post nasal drainage, and preventing sinus headaches. Many patients note an improvement in their symptoms within days. Treatments have a cumulative effect, often decreasing the need for other nasal medications. Symptoms may, however, reappear before the next treatment. The treatment is repeated monthly for a total of three (3) applications. It may be repeated as needed after that time, typically 3-4 times per year.
