Summary

We present a series of reconstruction of 47 patients with large full thickness cheek defects secondary to cancer ablative surgery. All patients were reconstructed primarily by bipaddle pectoralis major myocutaneous (PMMC) flap. The age of patients ranged from 25 to 85 years (mean 49.5 years). All patients were male. The size of the paddle used for mucosal defect repair ranged from 5×3 to 9×7 cm and the size of the paddle used for skin cover ranged from 4×4 to 9×8 cm. The total flap size ranged from 10×5 to 17×7 cm. One patient had complete loss of flap (2.12%). Sixteen patients had minor complications all of which settled with conservative management. The follow up period varied from 1 month to 4 years.

The modification adopted in bipaddling the flap was based on anatomical location of perforators to ensure good blood supply to both paddles of flap. Placing the flap horizontally with inclusion of nipple and areola increased the reach and size of available flap. We found the technique to be anatomically sound, technically easy and reliable. Precautions taken included proper assessment of reach of the paddle, placing not more than one-third of the paddle outside the muscle and securing the skin paddle to the muscle to avoid shearing of perforators during flap raising. We conclude that this technique is a useful alternative where microsurgical free tissue transfer is not possible or as a salvage procedure in selected large full thickness oral cavity lesions. However, the disadvantages of this method include loss of nipple and areola and technical difficulty in obese patients and females.

Anatomic details

For head and neck reconstruction, the skin between the nipple and midline based on the pectoralis major muscle is used, depending on the distance between the pivot point of the flap (the mid-clavicular point) and the recipient site. The thoracoacromial artery descends from its origin from the subclavian artery at the level of the mid-clavicular point in an inferomedial direction and anastomoses within the muscle with the direct branches of internal mammary and anterior intercostal branches of

Flap design and operative technique

On the basis of this vascular anatomy we developed the present method of bipaddling of the PMMC flap. The paddle is placed horizontally, including the nipple, extending from midline medially and crossing the lateral border of the muscle laterally (Figure 1, Figure 2(c)). Paddle for lining defect is placed around the nipple, which will be nourished by two sets of perforators (P2, P3). The paddle for the skin defect is placed on the medial edge of the muscle based on P1 perforators. As the paddle

Material and methods

This is a prospective study of 47 patients with postablative full thickness cheek defects and segmental mandibulectomy who underwent reconstruction with bipaddle PMMC flaps between May 2000 and July 2004. The age ranged from 25 years to 85 years (mean 49.5 years). All patients were male. Of these, 24 patients had lesions involving left buccal mucosa, 19 with right buccal mucosa, one involving the middle 1/3 of alveolus and floor of mouth, one with left alveolar carcinoma, one with right

Results

The size of the paddle used for mucosal defect cover ranged from 5×3 to 9×7 cm and the size of the paddle used for skin cover ranged from 4×4 to 9×8 cm. The total size of flap ranged from 10×5 to 17×7 cm (Table 1).

Of the 47 patients included in this study, all achieved satisfactory cover except one patient who had complete flap necrosis. We were unable to find the exact cause of this loss. This patient was later reconstructed with a folded forehead flap. Fifteen patients had minor complications,

Discussion

From the time of Ariyan's description7 in 1979, the pectoralis major myocutaneous flap has been the workhorse for head and neck reconstruction. Easy reach of the flap, reliable vascularity, technical simplicity, coverage of the exposed vessels by muscle after neck dissection and the ability to provide bulk made it a popular option amongst oncoreconstructive surgeons.

However, the availability of the skin paddle is limited for larger defects and most patients develop an unaesthetic neck

Conclusion

We conclude that this method of bipaddling the pectoralis major myocutaneous flap is a useful technique for reconstruction of complex composite cheek defects in male patients. It serves as a viable alternative to free tissue transfer or even as a salvage procedure. The method is technically easy and based on sound anatomic concepts.

    These situations require composite flaps. Pedicled flaps that reliably provide significant skin and soft tissue volume are the pectoralis major myocutaneous [129] and pedicled latissimus dorsi flap [130]. These still have an important role in the unfit patient, in failed free flap reconstructions, and in combination with free flap reconstructions.

    Repairing the cheek can be done with a large variety of methods either local or free flaps. Most authors agree that cheek reconstruction ideally needs double lining, although some teams use only one thick musculocutaneous flap (Adekeye et al., 1986; Adams-Ray and James, 1992; Ahmad et al., 2006; Kang et al., 2009). Tessier always used the Barron–Tessier flap to rebuild the inner lining of the cheek and mostly temporofrontal rotation flaps for the outer lining.

    Moreover, these procedures frequently fail to provide enough tissue, especially for large, full-thickness oral perforated defects involving the mandible or maxilla. The bipaddle pectoralis major myocutaneous flap can offer an alternative method for the reconstruction of large and full-thickness cheek defects (Ahmad et al., 2006). However, the drawbacks of this method include loss of the nipple and limitation of applicability in females or in patients who do not need a radical neck dissection.

    In a retrospective study, McLean and colleagues51 reported that they successfully use this flap to reconstruct 24 patients with temporal or cheek defects; however, the aesthetic outcome was not evaluated in this study. In addition, Ahmad and colleagues52 has used pectoralis major myocutaneous flaps designed with two skin islands for the reconstruction of full-thickness cheek defects. They emphasized that although it is not the first option for these defects, this technique can be useful when free flaps are not applicable or free flap failure has occurred.
