Background:

Endoscopic sinus surgery (ESS) for maxillary sinus lesions can be technically demanding.
Complete removal of soft tissue lesions via ESS is not always achievable.
Alternative approaches like the canine fossa approach may be required, increasing complexity.

Purpose of the Study:

To introduce a novel surgical instrument, the 'Derevator', designed to simplify the removal of soft tissue lesions from the maxillary sinus.
To facilitate the removal of pathological tissues through the middle meatal antrostomy during endoscopic sinus surgery.

Main Methods:

Development and application of the 'Derevator' instrument.
Utilizing the middle meatal antrostomy for access to the maxillary sinus.
