The surgery is done under general anaesthesia. The sinus opening will be widened with all the obstruction removed. The sinuses will be cleansed with the mucopus drained. The normal mucus clearance mechanism will be restored. The operation is performed inside the nose under endoscopic control with no external surgical scar.
In certain situation, it will combine with other nasal surgeries (such as septoplasty or polypectomy) to improve the access of the surgical field and the ventilation of the sinuses.
Postoperatively, the nose will be packed with dressing for hemostasis. The dressing will be removed in 1 to 2 days. Nasal saline irrigation should be started after the removal of nasal packing.
The complications include bleeding and infection which is not common. Rare complications include brain and eye injury.
