Background: Substances available for vocal cord augmentation procedure have their own advantages and limitations. Autologous fat is accepted to be one of the safest substance for augmentation. Objective: To evaluate the subjective and objective changes in vocal outcome following fat augmentation surgery for phonatory gaps. Materials and Methods: 30 patients with phonatory gap <2 mm were included in this prospective study. These consisted of sulcus vocalis (14), vocal cord atrophy (05) and vocal cord palsy (11). Per-operatively harvested umbilical fat was used for augmentation after mincing it and removing all the connective tissue. Follow-up of patients was done at 1, 3 and 6 months interval. Pre- and postoperative videostroboscopy was done. Objective analysis of voice was done using maximum phonatory time (MPT) and noise to harmonic ratio (NHR). Subjective assessment of voice was done using the voice handicap index (VHI) and subjective change in quality of voice as assessed by the patient. Results: Patients with early stage sulcus, vocal atrophy and vocal cord palsy, with small vocal gap, showed significantly good results after fat augmentation; however, results of patients with sulcus vocalis of grade II and III were not very satisfactory.
