T. Fdi, However iatrogenic PFP tend to better QOL than idiopathic PFP as means were all superior for iatrogenic PFP (32.08 versus 26.51, 30.88 versus 27.18 and 31.40 versus 26.89 for Physical, Social functions of FDI and Total FaCE score respectively)

, Our study permitted French translation and re-validation of both used PFP-specific QOL questionnaires, FDI and FaCE scale. French translation complied with the highest international guidelines for translation of self-assessment questionnaires. No difficulty in translation process and in French adaptation was encountered. In our validation study, the population size (67 patients) was consistent with the literature (19-23). PFP was idiopathic in 53.7% of cases, and iatrogenic in 29.9%. Given that our university hospital is a reference in term of otoneurosurgery, this over-representation of iatrogenic PFP is due to a recruiting bias. Moreover, idiopathic PFP tend to recover faster, PFP-specific QOL scale was validated in French language

. French,

, Swedish (20) and German (21) versions. For FDI, Cronbach's ? were 0.88 and 0.86 (test-retest) for physical function and 0.70 and 0.82 (testretest) for social function, These values are conformable with Spanish (0.77 for physical and 0.82 for social functions) and Swedish (0.86 for physical and 0.81 for social functions) validations

, 81) and social (0.86) domains of FDI and for FaCE (0.89, including sub-scores from 0.75 to 0.94). Considering Bland and Altman method, the bias (or means of differences) had confidence interval which included zero, Test-retest reliability was evaluated by ICC with a good range for physical

F. Fdi and . Volk, 21) found a weak but significant correlation between FDI and HB (-0.23, p=0.015 for physical function and -0.2, p=0.03 for social function) compared to correlation between FaCE and HB (p=0.0001). The validation study of Spanish FDI (19) found no significant correlation between social function of FDI and HB but significant for physical function (0.41, p=0.001). Kahn and al. (10) showed that the average difference in FDI social function scores between healthy subjects and PFP subjects was quite low, FaCE showed different correlation with clinical scores, House Brackmann and Sunnybrook. Correlation between FaCE and clinical scores was good except for Facial comfort and Social function subdomains
