Abstract
Abstract:
Introduction: Every human voice is unique because of anatomical, physiological, cultural, sociolinguistic and behavioural factors. Any disorder interfering with approximation, tension or vibration of vocal cord will change the quality, pitch and loudness of voice. The objective was to study the clinical profile, histopathological patterns and treatment options of benign lesions of larynx.
Materials and Methods: A prospective observational study was conducted for 80 cases clinically diagnosed as benign lesions of larynx. The inflammatory lesions were treated by conservative medical and speech therapy. Surgical intervention was done for neoplastic lesions of vocal cord.
Results: In our study, majority of patients 28(35%) were between 21-30 years of age. Male preponderence was seen. Voice abuse in 53 cases was the common predisposing factor. The most frequent symptom Hoarseness or voice change together constituted 66(82.5%), followed by vocal fatigue. Vocal cord polyp was the most frequent benign lesion in 17(21.25%) patients, followed by vocal cord nodule in 14, chronic laryngitis in 8 and vocal cord palsy in 7 patients. Microlaryngeal surgery was done in 49 patients.
Conclusion: The vocal cord polyp is the commonest benign laryngeal lesions producing hoarseness of voice as the chief complaint. There was a high correlation between clinical and pathological diagnosis of benign lesions of larynx.
