[Posttraumatic anosmia: olfactory event related potentials and MRI evaluation].

Objective: Using olfactory event related potentials (OERP) and magnetic resonance to evaluate olfactory function in patients with posttraumatic anosmia.

Methods: Twenty four patients with posttraumatic anosmia were reviewed retrospectively. A thorough medical history, physical examination, nasal endoscopy, T&T olfactory testing, olfactory event-related potentials, brain computed tomography scan and magnetic resonance image of olfactory pathway were performed in all patients.

[Diagnostic value for detection of aspergillus ribosomal RNA in fungal rhinosinusitis with hybridization in situ].

Objective: To develop a reliable, rapid assay for detecting pathogenic aspergillus species in fungal sinusitis.

Methods: Thirty-seven formalin-fixed and paraffin-embedded surgical tissue specimens from patients with fungal sinusitis were used in the present study. The aspergillus specific oligonucleotide probe was designed, commercially synthesized, and digoxigenin-labeled.

[Clinical research of patients with congenital anosmia].

Objective: To report on a series of patients with congenital anosmia, and to discuss its classification and clinical characteristics.

Methods: Eight patients with congenital anosmia were reviewed retrospectively. Four of eight cases were congenital anosmia with other abnormalities, including three cases with Kallmann's syndrome, one with hypoplasia of nasal cavity and nasal sinus.
