The full procedure of frontal sinusitis surgery is as follows:
After completion of general anesthesia, routine disinfection of the toweling was performed, and the nasal cavity was viewed endoscopically at 0°. Gauze or cotton pads infiltrated with epinephrine saline were used to shrink the nasal mucosa in the operative area, and the lateral leptomeningeal process was excised to reveal the natural opening of the maxillary sinus. The sieve bubble was excised with a stripper, reverse biting forceps, or nasal power planing system, and the nasal mound airspace was opened with biting forceps to fully expose the frontal recess.
The frontal sinus is explored with a curved suction device using a 30° or 70° angled nasal endoscope, and the inflammatory secretions in the frontal sinus are aspirated. If deeper penetration into the frontal sinus is needed, an axillary mucosal flap of the middle turbinate can be made to expose the bone. The maxillary frontal ridge is resected using a pterygoid sinus biting forceps or a nasal power grinder to open the anterior and inferior frontal sinus walls.
After removing the lesion and completing the frontal sinus opening, the surgical area was completely hemostatized, and the frontal sinus surgical area was filled and supported with absorbable hemostatic material. After the patient awoke, he returned to the ward.
