ABSTRACT
The objective of the study was to evaluate the effect of sternocleidomastoid (SCM) flap augmentation of the pharyngeal closure after total laryngectomy on the incidence of pharyngocutaneous fistula (PCF). Thirty patients with T4a laryngeal carcinoma and none of them receiving primary radiotherapy previously were divided into two equal groups. Group A patients had SCM flap augmentation of the pharyngeal closure after total laryngectomy. Group B patients had the standard pharyngeal closure without augmentation. Both groups were followed up for 30 days postoperatively for the development of PCF. The use of the SCM added about extra 15 min to the surgical procedure in all patients (p < 0.001). The shape of the suture line of the neopharynx was horizontal in 14 patients (7 in each group) while it was T-shaped in the remaining 16 (8 in each group). Neck dissection was done in all patients except only two patients who previously had the neck dissection done in combination with partial laryngectomy. Three patients in each group developed PCF either early (10 days or less postoperatively) or late (more than 10 days but less than 30 days postoperatively). There was no statistically significant difference in the length of hospital stay between the two groups. The use of SCM flap did not reduce the incidence of PCF after total laryngectomy.
