Deltopectoral flap revisited: Role of the extended flap in reconstruction of the head and neck

The extended deltopectoral flap is still the best choice in selected cases. During the period 1987-2004, 34 patients required reconstruction of the head and neck using this flap. Twenty-nine had had one or more failed attempts at microsurgical reconstruction after excision of cancer. Five were treated primarily. The flap was divided at least three weeks after the primary operation. All 34 survived, and there were no donor site complications. Twenty-seven patients had an uncomplicated outcome, but the remaining seven required later closure or skin grafting, usually under local anaesthesia, for complications. The extended deltopectoral flap has been used successfully to provide stable coverage of defects in the head and neck and should remain in the armamentarium of reconstructive microsurgeons.

Posterior tibial artery flap in poliomyelitis patients with lower extremity paralysis

Background: Poliomyelitis is a disease that can render affected individuals incapacitated to a variable degree. A normal lifespan is expected and therefore the patients deserve every effort at curative cancer resection and reconstruction. Those with lower extremity paralysis rely heavily on their upper limbs and torso for ambulation; therefore, their compromised limbs may be a better donor site for flaps. Methods: All poliomyelitis patients with lower extremity paralysis over a 20-month period who underwent head and neck reconstruction were selected for a retrospective review. Perioperative complications were noted and outpatient follow-up was performed. Results: Three patients underwent reconstruction of defects using the posterior tibial artery flap. Two patients required reconstruction of a buccal defect and one patient required soft palate reconstruction. All patients healed without complications and none required reexploration. At a mean follow-up of 10 months, there was no incidence of donor limb vascular compromise, cold intolerance, or long-term paresthesias. Conclusions: The posterior tibial artery free flap has been used successfully in the past; however, its popularity has been limited because of sacrifice of the posterior tibial artery. Nevertheless, in patients with lower extremity paralysis, this flap may fulfill the requirements of a thin, pliable flap with minimal hair that has a long pedicle and a reliable blood supply. Most importantly, the use of this flap obviates the need to use flaps that fulfill the same requirement, such as forearm flaps, that would be taken from patients’ functioning limbs.

Tubed deltopectoral flap for creation of a controlled esophagocutaneous fistula in patients with persistent choking following esophageal reconstruction with free diversionary jejunum

Esophageal reconstruction in patients with abnormal pharyngeal muscles or epiglottis may result in episodes of choking. The jejunal flap has been used to prevent choking by insetting the proximal end into the gingivobuccal sulcus and separating the digestive tract from the airway. A technique has been developed to deal with patients with aspiration due to collection of food near the nonfunctioning epiglottis. Between 1997 and 2004, 25 patients underwent reconstruction with jejunal flaps inset into the gingivobuccal sulcus. Postoperatively, 5 patients presented with episodes of choking. All patients underwent creation of an esophagocutaneous fistula using a deltopectoral flap. All flaps survived. Choking resolved and vocal performance was preserved in all patients. The jejunum, inset proximally into the gingivobuccal sulcus, has been successful in reconstructing patients unable to separate the airway from the digestive tract. The deltopectoral flap provides tissue for creation of a tubed flap and allows for the creation of a long fistula that prevents aspiration and can divert oral fluids away from a tracheostomy or a fresh wound.
