Introduction: The forming mechanisms of the pneumosinus dilatans have been investigated for a long time, but are still not totally clear. Besides the genetic and hormonal factors, an entire explanation of the pressure variation of the sinuses is still missing. A contradiction is found in the case of subjects suffering of choanal artesia, who in some cases have quite developed sinuses. The theory claiming that the ostium acts like a high pressure valve, is not valid in all these cases, considering the lack of intra-sinusal accumulated secretions.

Method: As a result of several years of investigations, we managed to find a different explanation for the hyperpneumatizations and the patology-causing location of these. Using relatively simple means to determine pressure variations in the maxillary, frontal, and sphenoidal sinuses lead us to conclude a theory that is exact opposite of the original.

Result/conclusions: The study is trying to give the logical explication to the exaggerated bone resorption in case of dominant negative pressurized oscillations.
