Anosmia is complete loss of the ability to smell. The SOP covers (only) permanent, total loss. The anosmia can arise due to a defect in the nose, the olfactory nerves or the brain.
Confirming the diagnosis
Diagnosis is based on history and examination findings, generally involving smell testing using dedicated kits or other materials with characteristic odours.
The relevant medical specialist is an ENT surgeon.
Additional diagnoses covered by SOP
- Complete, permanent loss of smell
Conditions excluded from SOP
- Partial loss of smell
- Temporary loss of smell
Time of clinical onset will generally be based on self report. Onset may be associated with an acute event such as head trauma or a stroke.
The only SOP worsening factor is for inability to obtain appropriate clinical management. As the SOP covers only permanent complete loss, there will be no treatment that can modify the course of the condition.
