Comment améliorer la rentabilité diagnostique des biopsies de la sphère oto-rhino-laryngée dans la maladie de Wegener : analyse anatomo-clinique de 49 biopsies chez 21 patients

We found that it was always better to perform biopsies targeted on macroscopic lesions. When there was no lesion, samples from paranasal sinuses obtained under GA had the highest diagnostic value in the head and neck region, whereas 90% of nasal systematic biopsies performed under LA were nonspecific. Moreover, we demonstrated that performing two further sections increased the sensitivity of histological examination by 7%.
