Bleeding on taking down the MAXILLARY CREST in a septoplasty comes from a branch of the GREATER PALATINE ARTERY, which reaches the anterior floor of the nose and antero-inferior septum through the incisive canal. It is controlled with packing, bipolar cautery or a greater palatine canal injection; the facial and superior labial arteries supply the vestibule and columella, and the posterior superior alveolar artery supplies the maxillary teeth and sinus.
