Background: In various studies, the platysma muscle was used as myofascial flap for intraoral reconstruction and as musculocutaneous flap for esophageal reconstruction. However it was not used as myofascial flap for esophageal reconstruction. In this preliminary study, an early postoperative result of the usage of myofascial flaps for esophageal reconstruction in the dog model is presented.Methods: Platysma myofascial flaps were used in reconstruction of circumferential defects of cervical esophagus in mongrel dogs. The platysma muscle and the superficial layer of deep cervical fascia were used as a myofascial flap in 13 young adult mongrel dogs. First 3 dogs were used to evaluate the size of esophagus and exploration of platysma. In the remaining 10 dogs, axial pedicle myofascial platysma flaps were harvested. The flaps were raised on the superficial cervical branch of omo cervical artery. The flaps were inverted to form a tube and interposed to 6 cm to 8 cm long defects created in the cervical esophagus.Results: Barium esophagograms were performed in 3 dogs at 21 days and in 5 dogs at 35 days postoperatively. Minimal narrowing and irregularity observed in the reconstructed segments at 21 days disappeared at 35 days. Migration of esophageal mucosa over the reconstructed segment was found to be irregular on the 21st day, however on the 35th day the whole segment was covered with esophageal mucosa as demonstrated by histological investigations.Conclusion: Platysma myofascial flap may be considered in reconstruction of cervical esophagus; however more experimental and clinical studies are needed before moving on to its usage in human.
