Intracordal hydrodissection method at vocal cord lesions by lateral microflap technique and its results

Abstract

The major objectives in the treatment of organic lesions located on the vocal cords are to remove of the lesions as well as establishing a normal quality voice pattern with physiological vibratuary pattern in postoperative period. In the intracordal submucosal injection technique, lidocaine HCI 0.5 cc 2% + adrenalin 0.025 was injected to the superficial lamina propria. This technique protected scar formation, vocal ligament and vocal muscle by enhancing lamina propria superficial layer’s distance from these anatomic structures. In twenty-one cases, lesions were removed by lateral microflap technique with the submucosal injection. Cases were assessed by stroboscopic inspection at preoperative and postoperative periods, noninjury to vocal ligament and muscle was observed by mucosal waves. The preoperative and postoperative glottic closure defects of the cases, mucosal waving patterns, amplitude and periodicity were compared with McNemar statistical method. Intracordal submucosal hydrodissection technique had a positive impact on the following improvements; glottic closure defect (p=0.000), mucosal wave patterns (p=0.008), amplitude (p=0.016) and periodicity (p=0.000), which were found statistically significant. In this study, the objective was to prevent vocal ligament and muscle by intracordal submucosal injection technique during the removal of the lesions located on the vocal cords.
