The 'swing-door' technique for uncinectomy in endoscopic sinus surgery

Area of Science:

• Otolaryngology
• Surgical Innovation
• Endoscopic Sinus Surgery

Background:

• Uncinectomy is a critical step in endoscopic sinus surgery.
• Traditional uncinectomy carries risks, including lamina papyracea penetration and orbital fat exposure, potentially leading to severe complications.
• Accurate identification of the natural ostium is essential for successful sinus surgery.

Purpose of the Study:

• To compare the safety and efficacy of a novel 'swing-door' uncinectomy technique against the traditional method.
• To evaluate the incidence of orbital penetration, natural ostium identification, and lacrimal apparatus injury between the two techniques.

Main Methods:

• A retrospective study comparing 636 uncinectomies using the 'swing-door' technique with historical controls (636 prior uncinectomies).
• Data collected included orbital penetration, identification of the natural ostium, and lacrimal apparatus injury.
• Statistical analysis (p-values) was used to determine the significance of differences between techniques.

Main Results:

• The 'swing-door' technique showed a significantly lower incidence of orbital penetration (0 vs. 6; p < 0.05) compared to the traditional method.
• Non-identification of the natural ostium was significantly reduced with the 'swing-door' technique (0 vs. 42; p < 0.001).
• Lacrimal apparatus injury occurred in one case with the 'swing-door' technique versus zero with the standard technique (p > 0.05).

Conclusions:

• The 'swing-door' uncinectomy technique is a safer and more effective alternative to the traditional method.
• This technique facilitates easier learning, precise uncinate removal, and improved identification of the maxillary sinus natural ostium.
• The findings support the recommendation of the 'swing-door' technique for routine endoscopic sinus surgery.
