[Correlation studies in goats about the membrane thickness and pressure of the maxillary and frontal sinuses].
OBJECTIVE
This study aimed to explore the differences of membrane thickness and pressure on the paranasal sinus membrane in goats and analyze their causes. The results can provide theoretical basis and guidance for the issues of the maxillary sinus floor augmentation related to the membrane.


METHODS
The membrane was cut into two sizes from every sinus membrane. The membrane was fixed in formalin to obtain tissue specimens for the membrane thickness study and pressure study. The correlation between the two parameters was then analyzed, and appropriate statistical methods and software were selected.


RESULTS
The top of maxillary sinus, the bottom of maxillary sinus and the frontal sinus membrane thickness were (410.03 ± 65.97), (461.33 ± 91.37), (216.90 ± 46.47) µm. The pressure were (260.08 ± 80.12), (306.90 ± 94.37), (121.72 ± 31.72) kPa. The mean differences of the membrane thickness between the top of the maxillary sinus and the frontal sinus, bottom and frontal, and top and bottom were statistically significant (P < 0.05). The mean differences in membrane pressure were also statistically significant (P < 0.05).


CONCLUSIONS
The membrane thickness and pressure of the top and bottom of the maxillary sinus are higher than those of the frontal sinus membrane. However, the thickness and pressure of the bottom membrane are slightly higher than those of the top membrane. Pressure and membrane thickness are positively correlated in the sinus membrane.
