PURPOSE OF REVIEW: The present review is focused on the main reconstructive options currently used after partial or circumferential resection of the hypopharynx and cervical esophagus. The advantages and disadvantages of pectoralis major myocutaneous (PMMC) pedicled flap, fasciocutaneous free flaps as radial forearm and anterolateral thigh (ALT), and visceral free grafts like jejunum and gastro-omental are overviewed. RECENT FINDINGS: For partial hypopharyngeal defects with limited extension to the cervical esophagus, no specific pedicled or free flap is deemed superior over others: the patient's body habitus and surgeon's preference remain the most important factors affecting the reconstructive choice. In contrast, after circumferential hypopharyngectomy, pharyngocutaneous fistula (PCF) and stricture rates of PMMC are higher than those obtained by free flaps. In the most recent series applying ALT and jejunum, PCF and stricture occurrence is comparable, whereas reduced mortality, overall complication rate, and donor-site morbidity of ALT and its better swallowing and speech outcomes have contributed to make this option progressively more popular. On the other hand, gastro-omental seems to offer an unparalleled amount of highly vascularized tissue to manage the difficult situation of salvage surgery after chemoradiation, even though complication rates remain not negligible and this technique has not been widely adopted. SUMMARY: The reconstructive armamentarium of head and neck surgeons involved in hypopharyngeal and cervical esophagus reconstruction should encompass every option described herein in order to appropriately deal with specific clinical needs and patient requirements. However, fasciocutaneous free flaps (especially ALT) seem to play an ever greater role in restoration of pharyngoesophageal continuity.
