Abstract: ABSTRACT:Soft palate tumors pose the challenge during reconstructive and rehabilitating procedures. Surgical resection of these tumors leads to velopharyngeal insufficiency (VPI). The primary effects of VPI are hypernasality and air-flow escape, while the secondary effects are abnormalities in speech articulation. Surgical revision along with speech therapy is a common approach to the treatment of VPI. Prosthetic management by means of speech aid prosthesis helps to reduce resonance, nasal emission and consonants errors. This clinical report describes the different stages of rehabilitation of velopharyngeal insufficiency defect following resection of malignant melanoma of left posterior alveolar ridge and soft palate. The speech aid prosthesis helped to rehabilitate the velopharyngeal insufficiency defect and aided in the diagnosis of extent of speech function improvement by perceptual and objective methods.
