Detaljert beskrivelse
Total or subtotal nasal amputation - defined as loss of at least three nasal subunits, or two subunits including the dorsum - results in major aesthetic and functional consequences with a significant impact on quality of life and social reintegration. Currently, two main rehabilitation approaches exist: surgical reconstruction (paramedian forehead flap as the gold standard, or free flaps such as the radial forearm free flap for larger defects) and nasal epithesis (implant-retained or adhesive prosthesis).
The choice between these techniques is often guided by the surgeon's experience and patient preference, in the absence of clear consensus, as very few studies have directly compared both options using standardised, patient-reported outcome measures.
The primary objective of this study is to compare functional and aesthetic outcomes between surgical reconstruction and epithesis groups using the SCHNOS questionnaire validated in French. Secondary objectives include comparison of subgroups by complications, comorbidities, patient profile, and identification of patients who switched rehabilitation modality.
Eligible patients will be identified via medical records by investigators at each participating centre. Those meeting inclusion criteria will be contacted by phone and then sent the information letter and questionnaire by mail or email. They may complete the questionnaire in paper form or via the secure Microsoft Forms platform. Questionnaire data will be exported to a centralised, password-protected Excel database for statistical analysis.
