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.
