title: Unexpected rare complication of the facial paralysis in a patient with an antrochoanal polyp following canine fossa puncture.
abstract: Canine fossa puncture (CFP) combined with endoscopic sinus surgery is a simple and effective method for treating antrochoanal polyps, particularly those that originate in the anterior, inferior or medial aspect of the antrum. Several complications can occur following CFP, including facial paraesthesia and dental numbness. However, facial palsy is extremely rare after CFP. We postulated that a possible mechanism of facial palsy is pressure injury to the soft tissues adjacent to the puncture site, which can damage the buccal branch of the facial nerve during CFP.
