Sinusitis symptoms may resemble those of a cold or an allergy. In addition to nasal congestion, mucus, or phlegm, there may also be headaches, facial pain, and a reduced sense of smell. If left untreated for a long time, it may become chronic and severe, affecting daily life.
Nowadays, most sinus surgery can be done by endoscopic surgery. Endoscopic surgical technique has been available for 30 years. This technique can be used for the treatment of nasolacrimal duct obstruction, exophthalmos, optic nerve compression, cerebrospinal fluid rhinorrhea, pituitary adenoma, and tumor of nose and paranasal sinus.
