It pierces the buccal fat, buccopharyngeal fascia and buccinator muscle then opens into the vestibule of the mouth opposite the upper 2nd molar tooth. The buccinator acts as a valve which prevents inflation of the duct during blowing. Running along with the duct superiorly is the transverse facial artery and upper buccal nerve, inferiorly is the lower buccal nerve.
