American Cancer Society Since the update of November 27, 2017* the possibility to rehabilitate the sense of smell is mentioned on the website pages "Living as a Laryngeal or Hypopharyngeal Cancer Survivor" with paragraph on "Restoring your sense of smell"" "If you have lost your sense of smell, or are smelling odors that aren't really there, olfactory rehabilitation might be another part of your recovery. Problems with smell (called olfactory disorders) can affect your appetite, sense of taste, food enjoyment, and how much you eat. Nearly all people who have had a laryngectomy will find they cannot smell things the way they did before. This is because air no longer travels through your nose. With olfactory rehabilitation, you can be taught techniques that cause nasal airflow and may help you recover your sense of smell. Examples are the nasal airflow-inducing maneuver (NAIM) and polite yawning. Olfactory rehabilitation (rehab) is available at some large medical centers. Talk to your health care team to learn more."
