Penetration of topical treatment to the olfactory cleft (OC), such as nasal drops, is greatly dependent on the position of the head when the treatment is administered. We aimed to examine the penetrance of nasal drops to the OC in two different head positions: the Mygind (lying head back) position and the Kaiteki position. Design and Setting The specimens were firstly positioned in Mygind, and thereafter in Kaiteki positions. Nasal drops mixed with blue food dye were administered into the nostrils in each of the head position. Endoscopic videos were recorded, and two blinded observers scored the extent of olfactory cleft penetration (OCP) using a 4‐point scale (0 = none, 3 = heavy). Participants Twelve fresh‐frozen cadaver specimens. Main outcome measures Penetration of the dye into the OC. Results The mean score of nasal drops penetrance to the OC in the Mygind position was 1.34 (standard deviation, SD = 0.92), as compared to 1.76 (SD = 0.65) in the Kaiteki position. The difference in the OCP score between the two groups was not statistically significant (P > .05). Conclusion Both Mygind and Kaiteki head positions are reasonable options for patients considering topical nasal drops for olfaction impairment. The preference of one position over the other should be determined by patient's preference and comfort.

The aim of the present study was to investigate how drops distribute within the nasal cavity when the "Kaiteki" position is performed. Thirteen healthy volunteers participated. Subjects were lying on the side with the head tilted and the chin turned upward. Blue liquid was used to visualize the intranasal distribution of the nasal drops. The investigation was carried out using photo documentation thorough nasal endoscopy; the intranasal distribution of the dye was judged by two independent observers in both a decongested state and a natural state where no decongestants had been used. With regard to the main criterion of this study, using the "Kaiteki" position, nasal drops reached the olfactory cleft in 96 % of the decongested cases and 75 % of the cases who had not been decong ested. However, this difference was not statistically different. Because the "Kaiteki" maneuver is not too difficult to perform, it is more likely that topical steroids can be helpful in cases of olfactory loss.
