Understanding of the anatomy and physiology of the vocal folds, availability of better diagnostic tools and precise instruments has spurred the development of newer techniques for the management of benign lesions arising in the vocal folds. As the propensity of the superficial lamina propria to regenerate is minimal, it is of paramount importance to maximally preserve it. Microflap surgery of the vocal folds is based on this principle. There exists a dichotomy in opinion regarding the role of subepithelial infiltration in microflap surgery; the disadvantages cited being possible confusion of the surgical plane following infiltration and hydrodissection of the normal basement membrane from the superficial layer of the lamina propria. A prospective study was therefore carried out in 30 cases of benign glottic lesions and microflap surgery was performed with and without infiltration in similar pathologic lesions. The vocal outcomes i.e. fundamental frequency, jitter, shimmer and maximum phonation time were audited. The advantages of this technique with a review of the literature are discussed.
