ABSTRACT

Background: Endoscopic rhinoscopy allows adequate visualization of nasal structures and thus facilitates diagnosis in rhinology. Systematically nasal preparation is performed with topical anesthetic and vasoconstrictor; however, its efficacy and utility have not been measured.
Objective: To evaluate the effectiveness of the application of two combinations for nasal preparation.
Material and Method: A prospective, random, simple blind study in which patients of both sexes were recruited in the private consultation of the main author during November 2016; their consent was obtained and they were randomized to receive a combination of lidocaine 10% nasal spray with 0.05% oxymetazoline or 2% lidocaine and epinephrine 0.005 mg/mL prior to performing nasal rigid endoscopy. Patients were asked to assess the degree of discomfort of drug application and the procedure and a comparison of the means for both groups was performed. Likewise, the degree of decongestion was evaluated by the author.
Results:: A total of 22 patients were studied, 12 men (54.5%) and 10 women (45.5%). The mean age was 41.45 ± 12.85 years. Both groups show very similar means for all variables without significant statistical differences.
Conclusion: There was no significant advantage of any of the combinations used for routine nasal preparation prior to endoscopy. There are factors that must be taken into account prior to the completion of the study and preparation of the nose with medications, such as pain threshold and patient age.
