RESUMO
Patient-reported outcomes questionnaires are accepted measurement tools to evaluate procedures results. The Rhinoplasty Health Inventory and Nasal Outcomes (RHINO) scale is an English-language validated and reliable quality-of-life instrument that evaluates both functional and aesthetic outcomes after rhinoplasty, and is not available in Hebrew. We followed the forward-and-back-translation method, defined by the European Organization for Research and Treatment of Cancer. Translation of the RHINO scale and merging it into one version were performed, following back-translation and validation on native Hebrew-speaking patients who underwent rhinoplasty and control healthy group. Lastly, we review and analyzed the results. The translated questionnaire had high reliability measures, demonstrating homogeneity (α value 0.800 in the rhinoplasty group and 0.896 in the control group), test-retest reproducibility with no significant difference (p = 0.5), and high agreement scores represented by the Bland-Altman plot (95% limits of agreement ranged from 8.78 to 9.80). Validity demonstrated by significant differences between the two study groups' mean questionnaire scores (p < 0.001 for rhinoplasty vs. controls, p < 0.001 for preoperative vs. postoperative, and p = 0.002 for postoperative vs. control group) and also between the aesthetic scores and functional scores of the rhinoplasty group before and after the surgery (p < 0.001). There were no reported understanding problems. The Hebrew version of the RHINO scale is a reliable and valid tool for pre- and post-rhinoplasty surgery outcomes measuring among Hebrew-speaking patients, and can improve coordination of expectations, follow-up, and quantify subjective evaluation of the surgery. Level of evidence: IV.
RESUMO
Objective: Nasal obstruction is a common complaint. The Nasal Obstruction Symptom Evaluation scale (NOSE) is a reliable validated tool used to assess the quality of life of patients with nasal obstruction. The purpose of this study is to validate the Hebrew version of the NOSE scale (He-NOSE). Methods: A prospective instrument validation was conducted. The NOSE scale was translated primarily from English to Hebrew and then back from Hebrew to English according to the accepted guidelines of the cross-cultural adaptation process. The study group included surgery candidates suffering from nasal obstruction due to a deviated nasal septum and/or inferior turbinate hypertrophy. The study group completed the validated He-NOSE questionnaire twice prior to the surgery and once again, a month post-surgery. A control group of individuals with no history of nasal complaints or surgeries was asked to complete the questionnaire once. Reliability, internal consistency, validity, and responsiveness to change of the He-NOSE were evaluated. Results: Fifty-three patients and 100 controls were included in this study. The scale showed excellent ability to discriminate between the study and the control group, exhibiting significantly lower scores in the control group (73.8 and 7 average scores respectively, p < .001). Good internal consistency (Cronbach's alpha .71 and .76) and test-retest reliability (Spearman rank correlation r = .752, p < .0001) were measured. Moreover, the scale revealed remarkable responsiveness to change (p < .00001). Conclusion: The translated and adapted He-NOSE scale can be a useful tool to be applied in both clinical and research fields when assessing nasal obstruction. Level of evidence: N/A.
