Objective The uncinate process may play a role in the amount of irrigation penetrance. In this cadaver study, we aimed to investigate if the addition of partial uncinectomy provides better maxillary sinus irrigation penetrance than balloon sinuplasty (BSP) alone. Study Design Cadaveric study. Setting Simulation laboratory at the Mayo Clinic in Florida. Methods Five fresh‐frozen human cadaveric heads (10 sides) were used to assess maxillary sinus irrigation penetration after 3 interventions performed sequentially: irrigation penetrance with no intervention, irrigation after BSP, and irrigation after BSP and partial removal of the uncinate. Penetrance was recorded with intrasinus endoscopy and scored by 4 blinded observers using a scale from 0 (no irrigation) to 5 (fully irrigated). The diameter of the maxillary ostium was measured before and after BSP. Internal consistency was evaluated with Cronbach’s alpha. Results Mean ostium size increased from 4.1 to 6.8 mm after BSP ( P =. 013). Cronbach’s alpha was 0.93. The median scores of irrigation penetration after no intervention, BSP, and BSP and partial uncinectomy were 2.5, 3, and 4, respectively. We found a significantly higher penetrance following partial uncinectomy plus BSP versus BSP alone ( P =. 008). Both interventions had a statistically significant difference in irrigation penetrance as compared with no intervention ( P =. 0001). Conclusion Maxillary sinus irrigation penetration increased from baseline after BSP. The addition of a partial uncinectomy to the balloon dilation of the maxillary sinus was associated with a statistically significant increase in irrigation penetrance scores as compared with BSP alone.
