Effect of tongue reconstruction following hemiglossectomy on articulation and speech intelligibility

Abstract

This study is aimed to investigate the articulatory functions of patients who have undergone tongue reconstruction following hemiglossectomy. The second aim of the study is to compare the speech intelligibility between hemiglossectomy patients who have undergone tongue reconstruction using pectoralis major myocutaneous with those hemiglossectomy patients who had undergone tongue reconstruction using radial forearm free flap.Fourteen patients who have undergone tongue reconstruction following hemiglossectomy as a treatment for oral cancer between the age of 30 to 60 years were taken up for this study. Tamil Articulation Test was used for assessing the articulatory functions of patients. The speech intelligibility of each patient was assessed using the Ali Yavar Jung National Institute for the Hearing Handicapped intelligibility rating scale. Analysis of articulatory errors revealed linguoalveolar consonants were more impaired when compared to other consonants. Patients with radial forearm free flap had somewhat better speech intelligibility compared to patients with pectoralis major myocutaneous flap reconstruction.The type of reconstruction also impacts the speech intelligibility. Effective intervention can be planned based on the comprehensive speech evaluation and analysis of articulatory error relative to place and manner of production.
