　　Purpose: To study the difference in the allowable pressure of the mucosa of the sinuses of goats (maxillary sinus and frontal sinus), analyze the reasons for this difference, and establish reasons for the mucosal problems in the maxillary sinus ridge. Provide guidance.

　　Method: Use a push-pull force gauge and homemade clamps and pressure tools to cut the mucosa of the required size from various parts of the sinus mucosa (maxillary sinus, mandibular sinus and frontal sinus mucosa) to measure the pressure resistance value and use matching. The t test determines the relationship between the parameters, and P is considered statistically significant. Results: The maxillary sinus mucosa of goats can withstand pressure of 260.08±80.12Kpa, the bottom of the sinus mucosa is 306.90±94.37Kpa, and the frontal sinus mucosa is 121.72±31.72Kpa. There was a statistically significant difference between the average mucosal pressure of the maxillary sinus and the frontal sinus, the bottom of the maxillary sinus and the frontal sinus, and the upper and lower sinuses (P\u003c0.05). The mucosa of the maxillary sinus bears more pressure than the frontal sinus, the mucosa of the maxillary sinus bears more pressure than the frontal sinus, and the mucosa of the maxillary sinus bears more pressure than the sinuses. I can.

　　Conclusion: There is a pressure difference between the mucosa of the frontal sinus, the upper part of the maxillary sinus and the lower part of the maxillary sinus, which increase in turn.
