Possibly the commonest skull disease in humans is sinusitis. Sinuses are cavities in the frontal bones, the sphenoid bones, the maxillary bone, and the mastoid processes of the temporal bone of the skull that are lined with mucous membrane and that open into the nasal cavity. Sinuses are often infected by bacteria, causing inflammation and producing severe pain.

With conventional medicine, acute sinusitis is treated with antibiotics; but chronic sinusitis is extremely difficult to eradicate.

As homeopathy is especially effective in chronic diseases, it has very effective treatment for chronic sinusitis also. It treats sinusitis effectively and also prevents recurrent infection of the sinuses.
