Abstract

Background Nasal irrigation is among the most widely used treatment modalities for sinonasal diseases. The extent of irrigation is well studied in operated sinuses but not for non-operated sinuses. Moreover, the preferred head positioning during irrigation is not known. Herein, we studied the extent of nasal irrigation in cadaveric heads with non-operated sinuses. Methods Nine cadaveric heads were used. Normal saline solution mixed with radiological contrast material was used to irrigate the nasal cavities with the heads in 2 different positions: standing-leaning-forward (SLF) and Head-down forward (HDF). After each irrigation, computed tomography images of the head were acquired. The extent of irrigation was assessed for each subunit of the sinonasal cavity. Results Irrigation was performed twice on a total of 18 sides, each time in 1 position. Nine subunits were evaluated: inferior, middle, and superior meati; the olfactory cleft; and the frontal, maxillary, anterior, and posterior ethmoid and sphenoid sinuses. The extent of irrigation was significantly better in the HDF position for the olfactory cleft (100% vs 33%), P-value=.001, frontal sinus (33% vs 11%), P-value=.002, maxillary sinus (78% vs 17%), P-value=.001, and anterior ethmoid sinus (89% vs 17%), P-value=.001. There was no significant difference in the extent of irrigation between the 2 positions for the other evaluated subunits. The overall extent of irrigation was 70.37% of the subunits in HDF position and 45.06% of the subunits for SLF position, P-value= .001 Conclusions Nasal irrigation reached the cavities of non-operated paranasal sinuses. However, while the extent of irrigation was limited in the SLF, it was well achieved in the HDF position. Studies on the clinical efficacy of irrigation in this position are recommended.
