Warning! This very short video may put you off your dinner. It shows pus and blood flowing out of the caudal maxillary sinus as the drill guide is removed. This is called sinus trephination and was necessary because a tooth root abscess and deep periodontal pocket resulted in a secondary sinusitis. Go to related post from last night to see a foley catheter stitched into the frontal sinus to facilitate flushing of this and the caudal and rostral maxillary sinuses. Most times, it is necessary to puncture the bulla of the ventral conchal sinus in order to create a communication channel between the Group I and Group II sinuses. In this case, there was already a communication. There are 7 paired sinuses in all and they are complicated in structure but oh, soooo fascinating. Deryck
