Salvage total pharyngolaryngectomy after failed organ-preserving therapy often results in composite defects involving the alimentary tract, trachea, and neck skin. This retrospective study examined combined use of the free jejunum flap and the pectoralis major muscle flap with skin graft for such a complex reconstruction. We reviewed 11 patients who(More)
OBJECTIVES Microsurgery is difficult to perform in necks that have been previously irradiated and operated upon because of the limited availability of recipient vessels. The objective of this study was to clarify the feasibility and safety of performing microsurgery in necks that are scarred and fibrous owing to previous treatment. METHODS Twenty patients(More)
Functional reconstruction of the anterior mandibular defect in combination with a significant glossectomy is a challenging problem for reconstructive micro-surgeons. In this retrospective study, clinical results were compared between mandibular reconstruction plate (MRP) procedures and double flap transfers. The subjects were 23 patients who underwent(More)
BACKGROUND During neck dissection, the current practice is to preserve the internal jugular vein in the majority of cases. However, sacrifice of bilateral internal jugular veins is required in rare cases. Simultaneous excision of both internal jugular veins is known to frequently cause fatal complications. Even if staged, bilateral internal jugular vein(More)
Soft-tissue defects after wide resection of groin sarcomas have been reconstructed with well-characterized flaps, such as rectus abdominis, gracilis, and anterolateral thigh flaps. To our knowledge, the use of superficial femoral artery perforator (S-FAP) flaps for this purpose has not been reported. We report on three female patients in whom groin defects(More)
OBJECTIVE Through our experiences in the parapharyngeal space (PPS) surgery, we have learned that it is possible to gain wide exposure of the PPS near to the skull base with a transcervical approach alone. Thus, we presumed that if this type of transcervical approach would be combined with a transoral approach, a less invasive oropharyngectomy without(More)
Postoperative dysphagia is not uncommon following significant glossectomy with laryngeal preservation. To develop effective treatments for this patient population, risk factors for postoperative dysphagia must be accurately identified. The objective of this retrospective study was to identify independent risk factors for dysphagia following microvascular(More)
INTRODUCTION To prevent postoperative pharyngocutaneous fistula (PCF) after total (pharyngo)laryngectomy, simultaneous coverage of pharyngeal anastomosis with vascularised flaps such as pectoralis major muscle, anterolateral thigh or radial forearm, has been reported to be effective. As an alternative to the invasive methods using distant flaps, we used the(More)
Reconstruction of a tracheal defect is a challenge because it often requires invasive surgery associated with relatively high morbidity. We recently invented a less-invasive method using a modified infrahyoid myocutaneous (IHMC) flap for the reconstruction of a tracheal defect in an 83-year-old male. A tracheal defect, the right half of the cricoid(More)
Reconstructing large defects of the extremities is a challenging problem for reconstructive microsurgeons. The latissimus dorsi musculocutaneous flap (LDMCF) is widely used for this purpose, but a skin graft is needed when the defect is wider than available flaps. We used flow-through divided LDMCFs to reconstruct large defects of the extremities in 5(More)
