Pectoralis major myocutaneous flap reconstruction of the laryngopharynx and cervical esophagus.
Advanced carcinoma of the hypopharynx and cervical esophagus is a formidable challenge to the skills of the head and neck surgeon. Radiation therapy is valuable as adjunctive therapy when combined with curative surgery, which is the primary treatment modality. The extent of anatomical disease associated with extensive neoplasia of the hypopharynx and cervical esophagus is frequently not amenable to total laryngectomy with local tissue repair. Surgical ablation usually requires an extended laryngectomy, which does not permit primary local repair. A previous report by this author, comparing all techniques historically and chronologically, indicated that the present impetus is toward procedures characterized by a one-stage primary repair with shorter completion times. Presently, the three most promising procedures that meet these criteria are the gastric transposition, free microvascular bowel transfer, and regional myocutaneous flap repair. Theogaraj, et al. reported the use of a partially tubulated pectoralis muscle flap over preserved posterior wall cervical esophageal mucosa in cases of short segment stenosis. Encouraged by these results, a technique using partial tubulation for long-segment stenosis was reported. The use of this technique was expanded to include the repair of the defect left after total ablation of the laryngopharynx and cervical esophagus. Over the past 40 months, 22 patients have undergone repair using partial tubulation of the pectoralis myocutaneous flap. This paper will discuss the technical aspects of the procedure and analyze the procedure as it relates to mortality, morbidity, and completion time. Low morbidity and a completion time of 18 days competes favorably with gastric transposition and free jejunal transfer. A rational approach to reconstruction using all procedures will be discussed.
