Objective: To corroborate the result of postlaryngectomy olfactory rehabilitation evaluating the efficacy of the Polite Yawning Technique (PYT) with rhinomanometry and odours with the Smell diskettes Olfaction test (SDOT). Materials and methods: Thirty-two laryngectomised patients were subjected to olfactory rehabilitation consisting of 15-minute training and independent exercising for two weeks. The sense of smell and nasal airflow in laryngectomised patients were examined before and after implementation of PYT. Results: The differences in SDOT results prior to and after introduction of PYT were statistically significant, most patients achieving better results after rehabilitation. A significant positive correlation was obtained in results of SDOT and rhinomanometry prior to and after introduction of PYT. The results of measurements after rehabilitation showed that 75% of patients had improved nasal breathing, 78% of patients had a better sense of smell and 40% of patients became normosmic. Conclusions: PYT has proved to be an effective method in olfaction rehabilitation following total laryngectomy. Using rhinomanometry, evaluation of the rehabilitation success is substantiated while the technique is simplified.
