Pectoralis Major Island Flap Research Articles

Modified harvesting technique for pedicled pectoralis major muscle flap after extended manubrial resection in case of recurrent cervicothoracic junction tumors.

The problem of the replacement after manubrial resection can be solved standardly through apedicled pectoralis major muscle flap (PMMF) defect coverage, harvested thought an accessory incision. We recently established an alternative and easier harvesting technique, also in critical cases (patients with recurrent tumor and after radio-chemotherapy), that improves aesthetic outcome and allows harvesting an adequate muscle flap for an optimal chest wall coverage. Asingle center retrospective analysis between 2017 and 2020 was performed. Flap harvest was performed subcutaneously using the same incision resections line, thereby sparing the clavicular and upper sternocostal aspects of the pectoralis muscle. Fifteen patients with recurrent tumors after radio-chemotherapy and involving the upper thoracic inlet underwent manubrial resection with associated extended upper mediastinal dissection and replacement using apectoralis major island flap following our harvesting technique. The majority (70%) of patients had an uneventful course of recovery and showed satisfying aesthetic results and low donor site morbidity. Four (26%) patients had major complications that required surgical revision. All patients had early postoperative shoulder mobilization without functional deficit or aesthetic deformity. Pedicled pectoralis major muscle flap (modified harvesting) provides an adequate replacement of the upper thoracic inlet, with excellent aesthetic and functional results, also in high risk patients.

The Pectoralis Major Island Flap: Short Scar Modified Muscle-Sparing Harvesting Technique Improves Aesthetic Outcome in Reconstructive Head and Neck Surgery

Background: Pectoralis major flap reconstruction is often associated with large unappealing scars in head-neck surgery. We recently established an alternative harvesting technique that improves aesthetic outcome. Objectives: The objective of this study was to demonstrate a modified surgical technique that harvests the pectoralis major muscle as an island flap and focuses on minimizing incision lines and applying a muscle-sparing approach. Methods: A retrospective analysis covering the period 2008–2018 was conducted. Patients who underwent pectoralis major island flap reconstruction for fistula prophylaxis after salvage laryngectomy at the Medical University of Innsbruck were included. Flap harvesting was performed subcutaneously using two small incision lines, thereby sparing the clavicular and upper sternocostal aspects of the pectoralis muscle. Results: Twenty-three patients with squamous cell carcinoma of the larynx (n = 19) or pharynx (n = 4) underwent salvage laryngectomy and consecutive reconstruction using a pectoralis major island flap and our muscle-sparing technique. Mean overall operation time was 147 ± 48.6 min. The majority (70%) of patients had an uneventful course of recovery and showed satisfying aesthetic results and low donor site morbidity as compared to traditional harvesting techniques. Six (26%) patients had major complications that required surgical revision. Three (13%) cases were complicated with fistulas. Conclusion: The pectoralis major island flap is shown to be reliable in otolaryngeal surgery. This surgical technique minimizes scarring and preserves thoracic wall architecture by taking a less invasive approach, thereby improving aesthetic outcome and reducing overall patient morbidity.

The nerve supply to the clavicular part of the pectoralis major muscle: an anatomical study and clinical application of the function-preserving pectoralis major island flap.

The purpose of this study was to investigate the nerve supply to the clavicular part of the pectoralis major muscle so that the innervation to this part can be maintained in the muscle-preserving pectoralis major island-flap transfer. Although methods have been described that include a limited portion of the muscle while leaving the upper parts undisturbed with an intact motor innervation, reports on anatomical studies of this nerve supply are brief. The distal distribution of the nerves, the spatial relationship to the main vascular pedicle, and the ways to preserve them during surgical procedures remain unclear. Surgically relevant features of the clavicular part of the pectoralis major muscle were studied by dissection. The nerve supply to this part was examined on 11 sides of eight formalin-fixed cadavers. Two fresh cadavers were used for dissection, intraarterial polymer injection, and application of a nerve-preserving surgical technique. In all subjects, a separate nerve innervated the clavicular and upper medial sternocostal portions of the pectoralis major muscle. This nerve arises craniomedial to the main vascular pedicle of the flap and divides into several branches. These branches run in a fascia on the deep surface of the pectoralis major muscle, superficial to the origin and distal course of the vascular pedicle. Most branches to the clavicular part end medial to the coracoid process. The course of the branches to the upper sternocostal part is more medial. Based on their anatomical findings, the authors propose a surgical technique for transfer of the pectoralis major island flap to the head and neck area through a tunnel in the deltopectoral groove, lateral to the origin of the vascular pedicle. Head and neck reconstruction was performed using this technique. The presented method is a muscle-preserving procedure that maintains maximal donor-site function and morphology.

The “double faced” pectoralis major island flap: A valuable alternative in full-thickness cheek reconstruction

Experience with cheek reconstruction after resection, using a single pectoralis major island flap with its inner surface previously split-skin grafted, is presented. No complications were observed in the initial series of 4 cases. The method appears to be a valuable alternative in selected cases, whenever local tissues cannot be used for reconstruction.

Primary reconstruction of a major loss of lower jaw by an animal bite using a “rib sandwich” pectoralis major island flap

A 20 weeks pregnant woman was bitten by a wild bear which took away the central portion of her jaw. A single stage primary reconstruction was performed using a composite pedicled pectoralis major “rib sandwich” island flap. This provided continence of the mouth, allowing her to feed herself within 3 weeks of the operation and to speak reasonably by 6 weeks.

Mediastinal Tracheostomy

Upper airway obstruction in primary or recurrent carcinomas of the head and neck extending into the mediastinum may demand surgical intervention despite severe technical difficulties in patients with tumors previously considered inoperable. In fact, many of these tumors may be operable and some perhaps curable. A technique has been developed based in part on our experience with previously described procedures. A preliminary sternal split is used to demonstrate the extent of the mediastinal involvement as well as to provide enhanced exposure and proximal control of the great vessels. The pectoralis major muscle is used with a generous flap of overlying skin comprising nearly half of the anterior portion of the chest. A tracheostomy is then created in a fashion similar to the placement of a cardiac valvular prosthesis by creating a circular defect in the pectoralis major flap and suturing it to the tracheal remnant. This technique offers a reasonably safe and reliable means of creating a low anterior mediastinal tracheostomy for tumors previously considered inoperable. The preliminary sternal split makes the procedure safer and easier to perform, and the use of a very large pectoralis major island flap allows for reliable closure of the resulting mediastinal and sternal defects.

The pectoralis major island flap for coverage in the upper extremity

From July 1, 1978, to July 1, 1980, 26 patients required pedicle flap coverage for acute skin loss defects in the hand and upper extremity. Eighteen patients had groin or abdominal flap coverage, and the pectoralis major island flap (PMIF) was used in eight patients. The circumstances of injury were approximately the same in both groups, consisting of a gunshot wound or electrical injury in over half of the cases. The PMIF was selected more often in proximal and dorsal injuries of the forearm and wrist and in older patients. Two of 13 groin flaps sustained partial necrosis, but none of the abdominal or PMIF flaps necrosed. The principle advantages of the PMIF in these selected cases was fourfold: (1) an extremity placed in a less dependent, sling-like position, (2) mobility, (3) reliability, and (4) a complete inset into the defect. The chest wall donor site defect, however, must be given some consideration.

It is the author's belief that the recently introduced island type of pectoralis major myocutaneous flap ( Ariyan, 1979) will eventually replace the deltopectoral flap as the preferred flap for the majority of head and neck reconstructions.
