Where is the incision made for sinus surgery?

Surgery for frontal sinusitis generally does not require open incisions. The procedure is performed under nasal endoscopy and completed entirely under a microscope, with no external cuts.

Additionally, frontal sinusitis is a type of sinusitis and can be treated using surgical methods for sinusitis. The specific surgical procedure is as follows:

1. The patient is placed in a supine position and administered general anesthesia. Mucosal surface anesthesia is achieved using cotton strips soaked in 1% tetracaine with epinephrine to anesthetize and shrink the nasal turbinates. The surgeon stands on the patient's right side.

2. The surgeon inserts a nasal endoscope through the patient’s nasal cavity to observe internal structures.

3. Under a 30° or 70° endoscope, use a 45° or 90° ethmoidectomy forceps to remove the anterosuperior portion of the uncinate process up to the lamina papyracea and near the skull base.

4. If the agger nasi cell is extensively pneumatized, it may first be removed to fully expose the frontal recess. First, identify the roof of the ethmoid sinus and locate the anterior ethmoid artery. Just anterior to this artery lies a small recess, and the frontal sinus opening is located anterior to this recess. When the frontal sinus opening is difficult to identify, first locate the anterior ethmoid artery and then search forward for the frontal sinus opening.

5. The location of the frontal sinus opening can be determined by observing the flow of secretions from it. Carefully remove diseased tissue surrounding the frontal sinus opening to fully expose it.

6. Use a curved suction tip to probe the frontonasal duct, further removing bony fragments around its opening to enlarge it. Make every effort to preserve the mucosa surrounding the frontonasal duct opening.

7. After surgery, hemostatic gauze and high-molecular-weight expanding sponge are placed in the nasal cavity. These packing materials are removed after 48 hours. Postoperative management includes enhanced anti-inflammatory treatment and hemostasis.
