Abstract
Objective: To explore the methods and effects of pectoralis major myocutaneous flap in pharyngolaryngeal cancer surgery. Methods: Among 23 cases of pharyngolaryngeal cancer patients, the surgical procedure was based on pathologic conditions, and the surgical defects were repaired by pectoralis major myocutaneous flap. Results: Among 23 patients, there were 1 case of skin flap necrosis, 4 cases of pharyngeal fistula, 1 case of hypopharyngeal esophageal stenosis; except 1 case of pharyngeal fistula died of carotid artery rupture caused by infection, 1 case of hypopharyngeal esophageal stenosis required a gastric tube, and the rest patient’s swallowing function is normal. Conclusion: The blood supply of pectoralis major myocutaneous flap is reliable with the tissue volume enough for reconstruction. It turns out to improve patient survival and postoperative quality of life with the application of pharyngolaryngeal cancer surgery.
Highlights
Pectoralis major myocutaneous flap (PMMF) is a pedicle flap technique used in reconstructive head and neck surgery [1] [2]
Among 23 cases of pharyngolaryngeal cancer patients, the surgical procedure was based on pathologic conditions, and the surgical defects were repaired by pectoralis major myocutaneous flap
Pharyngeal fistula appeared 7 days after surgery, musculocutaneous flap necrosis, followed by secondary neck infection, carotid rupture died half a year later. 2 cases with musculocutaneous flap were operated from hypopharyngeal esophageal entrance pathway, 1 case of hypopharyngeal esophageal stricture was discharged, 1 case with a nasogastric tube was discharged, and the patient returned to normal swallowing function. 2 patients with tongue root cancer developed mild cough after operation, and the symptoms disappeared at 3 months and 6 months respectively. 7 cases cervical skin defected repaired with PMMF, all healed
Summary
Pectoralis major myocutaneous flap (PMMF) is a pedicle flap technique used in reconstructive head and neck surgery [1] [2]. With the development of otolaryngology, head and neck surgery, the PMMF is widely used to repair large area tissue defects. The PMMF has abundant blood supply, strong anti-infection ability, low necrosis rate, and easy survival; the transferable skin area is large, and at the same time, it can provide a large number of muscles to repair defects; the muscle pedicle is long, and the flap can be extended to repair multiple types of composite defects of the head and neck, meeting most of the repair requirements of the head and neck; during the operation, there is no need to change the patient’s position, and the wound of the donor site can be directly sutured without skin grafting; the operation is simple, does not require vascular anastomosis, and is easy for clinical promotion.
