This is a quantitative and objective study using spirometry to verify that the airway is maintained in the case of intranasal packing with a Doyle Combo Splint (Boston Products, Westborough, MA, USA) [1]. The patient's discomfort during the nasal packing was scored on a survey using a visual analogue scale. Thus, the topic of this study is not a new one in which the airway was maintained after the nasal packing with the Doyle Combo Splint, and patient's discomfort was reduced because nasal respiration was possible. The researchers evaluated the patients using plain X-ray images postoperatively and immediately after removing the nasal packing. They reported that there was no difference in the degree of support for the reduced bone in the control group and experimental group using a Doyle Combo Splint with. Considering the purpose of the nasal packing, this result is the main point of this study.However, the research method is insufficient for producing objective scientific results. Plain X-ray images can be changed depending on the angle because they are two-dimensional images. Some simple fractures can be displayed well on dedicated X-ray projections. On the other hand, complex fractures can only be partially evaluated because of the overlap of the various structures in the craniofacial skeleton, the complexity of which demands considerable expertise in evaluation [2].
