Generally speaking, neither cold nor hot compresses are necessary for sinusitis, because sinusitis is mainly an acute or chronic bacterial infection of the sinuses. Common symptoms include nasal congestion, purulent nasal discharge, and reduced sense of smell. Some people may also experience headaches and dizziness. The main treatment is still medication, and it is also possible to consider rinsing the nasal cavity with saline solution, regular follow-ups, and if the inflammation is severe, sinus opening surgery may need to be considered, which currently mainly involves endoscopic sinus surgery. Overall, neither hot nor cold compresses have a therapeutic effect on sinusitis, so they are not recommended.
