Rhinoplasty: French validation of the MiRa scale.

[AIMS] The aim of this study was to translate the MiRa scale into French and validate its use for French-speaking surgeons.

[MATERIAL AND METHODS] ISPOR and WHO recommendations were used to carry out the translation process from English to French in five steps. The MiRa scale is a validated analysis scale of nasal dysmorphoses. Few tools are available in French for French-speaking surgeons. ISPOR and WHO recommendations were used to complete the five-step translation process from English into French. To assess the reliability of the MiRa scale-French version, we statistically compared intra-observer repeatability (comparison of scores obtained when one observer assessed each patient twice at a one-month interval) and inter-observer repeatability (comparison of scores obtained when 2 observers assessed the same patient) using the Wilcoxon test and the intraclass correlation coefficient (ICC) (α=5%).

[OBJECTIVES] Our goal was to obtain a translation of the idea or concept rather than a literal translation to enable good intra- and inter-observer repeatability.

[RESULTS] Each step allowed us to make changes gradually working towards a conceptual translation equivalent to the original version.

[CONCLUSION] The MiRa scale is the only aesthetic analysis scale validated in the literature for nasal dysmorphoses. The combined use of two sets of translation recommendations, with a five-step translation-back-translation process, made it possible to obtain a French version perfectly in line with the original. This version is usable by French-speakers.
