Olfactory function in laryngectomised patients: tracheo-oesophageal oesophageal speech.

Objective: This study aimed to evaluate olfactory function in patients rehabilitated with oesophageal (ES) voice or tracheo-oesophageal (TES) prosthesis to further verify whether there were differences in smell alterations depending on voice rehabilitation modality.

Methods: A total of 40 patients who had undergone total laryngectomy participated in the study. Speech rehabilitation was achieved through TES in 20 patients (Group A) or ES in 20 patients (Group B).
