Long-term Results of Olfaction Rehabilitation Using the Nasal Airflow–Inducing ("Polite Yawning") Maneuver After Total Laryngectomy

Abstract

The effectiveness of the NAIM, or so-called polite yawning technique, for the rehabilitation of olfaction in individuals who have undergone total laryngectomy was reconfirmed. Long-term olfaction rehabilitation was achieved in about 50% of the patients, but more intensified training may be needed to increase the percentage of successfully rehabilitated individuals. The SDT is an effective and simple test for the assessment of olfaction acuity after laryngectomy.
