Objectives/Hypothesis There is evidence that the olfactory system can be modulated by repeated exposure to odors, a procedure called training . The aim of this study was assess effectiveness in patients with postinfectious and post‐traumatic dysfunction. Study Design Prospective 119 Methods Two groups (postinfectious post‐traumatic) performed (n = 49 n 23, respectively) over period 16 weeks were compared two control same etiology 32 15).

OBJECTIVE Olfactory neuroblastoma constitutes a rare and, in clinical terms, biologically variable tumor of the nasal cavity, paranasal sinuses, and base skull presents challenge to modern multidisciplinary therapy. Generally acknowledged prognostic factors standard therapy fail exist. METHODS Between 1975 2000 we diagnosed treated 26 patients with an olfactory neuroblastoma. According Kadish's classification, 1 patient (4%) showed stage A, 16 (53%) B, 11 cases (43%) C. Hyams grading was...
