Frontal sinus surgery: endoscopic technique and preliminary results.

Area of Science:

• Otolaryngology
• Endoscopic Sinus Surgery
• Surgical Anatomy

Background:

• Endoscopic frontal sinus surgery is challenging, with high risks and failure rates.
• Accurate surgical anatomy is crucial for safe and effective frontal sinus access.
• Previous techniques often lacked predictability and had suboptimal outcomes.

Purpose of the Study:

• To clarify surgical anatomy for safe and predictable endoscopic frontal sinus surgery.
• To describe a detailed surgical technique for accessing the frontal sinus.
• To evaluate the efficacy and safety of this refined surgical approach.

Main Methods:

• Study of 200 consecutive patients undergoing endoscopic frontal sinus surgery.
• Detailed description of surgical technique: CT identification of uncinate process attachments, microdebrider removal, agger nasi cell removal, and frontal sinus patency verification.
• Inclusion of computed tomography (CT) and endoscopic findings, patient outcomes, and complication assessment.

Main Results:

• Achieved 90% frontal sinus patency in short-term follow-up (average 12.2 months).
• No major complications were reported.
• Minor complications included frontal recess stenosis and polypoid mucosa, which can lead to recurrence.

Conclusions:

• A thorough understanding of anatomical variations, particularly the uncinate process, is essential.
• Precise surgical removal of superior uncinate attachments ensures access via the natural ostia.
• This technique provides a more reliable and patent surgical pathway for the frontal sinus.
