Single stage reconstruction of complex head and neck defects involving the skin with a single ALT flap: A ten year review.

ABSTRACT: Background:Multicomponent defects of the head and neck involving the cervical skin pose a reconstructive challenge for microsurgeons and usually requires two flaps. However, many patients who undergo such surgical treatment had prior treatment with radiotherapy and the availability of recipient vessels for free flap reconstruction may be limited. The purpose of this study was to review our experience in the reconstruction of these extensive head and neck defects using a single ALT free flap. Methods:A total of 21 patients with complex defects of the head and neck involving multiple anatomical subunits, including the overlying cervical skin, underwent reconstruction with a single ALT flap. The clinical, functional, and aesthetic outcomes of these patients were reviewed. Results:The mean hospital stay was 24 days. There was one total flap loss due to pedicle thrombosis. The patient underwent a further ALT reconstruction with no postoperative complications. Cervical fistulas occurred in three patients, and all fistulas were healed by simple wound packing. Three patients with tracheal defect had a functional tracheostoma with adequate stomal patency. A modified barium swallowing study was performed on each patient, and all of them achieved total oral intake. Among them, two patients tolerated only a pureed diet. Conclusions:Complex neck reconstruction can be accomplished with a single ALT flap with good clinical and functional results, minimal morbidity and quick recovery.

Project description:Background:Poor nutritional status among patients with advanced stage head and neck squamous cell carcinoma (HNSCC) is common. Albumin is a common indicator of nutritional status and has been shown to be a predictor of oncological outcomes and perioperative morbidity. This study aims to determine the prognostic value of the serum albumin level among patients with advanced HNSCC undergoing surgery with simultaneous free flap reconstruction. Methods:A total of 233 patients with advanced head and neck cancer undergoing tumor resection and immediate microvascular free flap reconstruction in a tertiary referral center were enrolled retrospectively between January 2009 and December 2011. Statistical analyses including Pearson's chi-squared test were used to determine whether there was a significant difference between each selected clinical factors and postoperative major wound infection. Multiple regression analysis was performed to reveal the relationship between postoperative major wound infection and clinical factors. Kaplan-Meier curves and multivariate Cox regression were applied to analyse survival outcome for overall survival (OS), disease-specific survival (DSS) and disease-free survival (DFS). Results:Postoperative serum albumin level (p < 0.001) and tumor location were both significantly associated with postoperative major wound infection (p = 0.018) in univariate analysis. Multiple regression analysis showed a higher risk of postoperative major wound infection among patients with postoperative hypoalbuminemia than in their counterparts (odds ratio [OR] 9.811, 95% CI [2.288-42.065], p = 0.002). Patients with a tumor located over the hypopharynx experienced increased risk of postoperative major wound infection (OR 2.591, 95% CI [1.095-6.129], p = 0.030). With respect to oncological outcomes, preoperative serum albumin level is a significant independent prognostic factor for overall survival (OS), disease-specific survival (DSS) and disease-free survival (DFS). Conclusions:Postoperative hypoalbuminemia is a useful indicator for the development of postoperative complications. In addition, preoperative hypoalbuminemia is a negative prognostic factor for patients who have undergone tumor excision and free flap reconstruction for the advanced stage of HNSCC.

Project description:BackgroundExtensive through-and-through oromandibular defects after advanced oral carcinoma excision pose a reconstructive challenge for the head and neck surgeon. These complex oromandibular wounds often involve the mandible, oral and/or aerodigestive mucosa, and the external skin. As a result, these defects are often not amenable to reconstruction with a single flap due to the volume of soft tissue needed and the three-dimensional reconstructive requirement. The use of two free flaps has often been suggested to overcome this reconstructive challenge. A simpler and less technically demanding way to deal with this may involve the use of a free flap in combination with a pedicled regional flap. We present our experience of the use of a simultaneous microvascular fibula free flap (FFF) with a pectoralis major myocutaneous flap (PMMC) for addressing these defects.MethodsA retrospective chart review was performed of patients treated with a FFF and PMMC combination for the reconstruction of oromandibular defects at the University of Mississippi Medical Center (Jackson, MS) between October 2013 and February 2016. A minimum follow-up of 12 months was required. Data collected included the extent and location of tumor involvement, size of the postablative defect, tumor histology, clinical and pathological staging, length of follow-up, functional outcomes, and associated complications.ResultsA total of three patients were identified to have been treated with the above technique. Defects repaired involved through-and-through mandibular defects with associated oral mucosa and external skin defects. In all cases, the FFF was used for restoring bony continuity with the skin paddle used to reconstruct the intraoral lining. The PMMC was used for reconstruction of the external skin defect and for providing soft tissue bulk. The average size of the fibula skin paddle used for intraoral reconstruction was 7.7 cm × 11.7 cm. The average size of the PMMC paddle was 7.3 × 9 cm. The mean follow-up was 21.7 months. Both the FFF and PMMC survived in all cases, although postoperative wound healing complications occurred in two of the three patients. There was one partial flap loss. Two patients regained good oral intake while one patient tolerated oral intake but was PEG tube-dependent.ConclusionsThe combination of pectoralis major myocutaneous flap and a vascularized free fibular flap is a viable option for the reconstruction of complex through-and-through oromandibular defects. This technique may be useful when a single microvascular free flap is not sufficient for reconstruction of such defects.
