[Puncture of the maxillary sinus with the Sinojet]

A method is presented by which "blind" puncture of the maxillary sinuses can be performed and which is based on the use of the Sinoject puncture set. This technique has been applied so far in 36 patients. It enables puncture of the maxillary sinus with minimum trauma and hardly any pain. The fact that the puncture needle is pushed via a spring coil to a depth of only 1 cm greatly reduces the risk of injuring neighbouring structures such as the posterior wall of the maxillary sinus. Contrary to the classical procedure a small drainage tube is introduced into the maxillary sinus simultaneously with the puncture. Due to the low tendency to bleeding when this procedure is applied, the method is particularly suitable for use with patients with disturbed coagulation, as well as for AIDS patients.
