Olfactory Disorders (Dysosmia): Examination

A comprehensive clinical examination is the basis for selecting further diagnostic steps:

  • General physical examination – including blood pressure, pulse, body weight, height; furthermore:
    • Inspection (viewing).
      • Skin and mucous membranes
    • Auscultation of the lungs
  • ENT medical examination – including nasal endoscopy (nasal endoscopy; nasal cavity mirroring) or endoscopy (mirroring) of the nasal cavity and nasopharynx incl. inspection (viewing) of the olfactory fissure and the skull base (eg, to exclude a mechanical obstruction of the olfactory fissure) possibly with biopsy (tissue sampling) [due todifferential diagnoses:
    • Chronic recurrent rhinosinusitis (RS; simultaneous inflammation of the nasal mucosa (“rhinitis”) and the mucosa of the paranasal sinuses).
    • Chronic sinusitis (sinusitis).
    • Polyposis nasi – occurrence of multiple nasal polyps.
    • Septum deviation (deviation of the nasal septum).
  • Neurological examination – including examination of motor function, sensitivity, coordination, and cranial nerve function [due todifferential diagnoses:
    • Familial dysautonomia (Riley-Day syndrome) – genetic disorder leading to autonomic nervous system dysfunction.
    • Alzheimer’s disease
    • Parkinson’s disease (shaking palsy)
    • Multiple sclerosis (MS)
    • Neoplasms in the area of the brain
    • Progressive paralysis – manifestation of neurosyphilis, which proceeds as psychosis with neurological deficits]
  • Psychiatric examination [due todifferential diagnoses:
    • Depression
    • Psychosis]
  • Health Check
