AbstractThe aim of this study is to determine whether rhinologic preoperative evaluation and pretreatments reduce intranasal trauma and decrease postoperative complications, such as nasal obstruction and epistaxis, in patients undergoing 2-jaw surgery with nasotracheal intubation. This study included 360 patients with malocclusion (Class III) who underwent 2-jaw surgery under general anesthesia via nasotracheal intubation in our hospital from January to December 2013 and categorized into 3 groups. Nasotracheal intubation was performed according to the nasal cavity the patient was able to breathe comfortably (Group I). The site of nasotracheal intubation was decided by 1 rhinologic specialist who evaluated preoperative dental computed tomography (Group II). The site of nasotracheal intubation was decided upon nasal endoscopic findings, dental computed tomography evaluation, and rhinologic pretreatment (Group III).Group II and Group III showed less damage to the nasal mucosa compared with the nasal status of Group I. Upon comparing Group II and Group III, Group III showed better overall status of the nasal mucosa compared with Group II. Visual analogue scale scores for nasal obstruction were pretty similar for all groups on the first postoperative day. In Group III, the nasal mucosa, however, was improved to that of preoperative status on the third postoperative day.In conclusion, it may be useful to pre-evaluate the mucosal and anatomical status of the nasal cavity to select patients requiring rhinologic pretreatment and decide the site for nasotracheal intubation to minimize complications arising from nasotracheal intubation.
