RESUMO
ABSTRACT: Recipient vessel selection in head and neck reconstruction is based on multiple factors, including defect size and location, patient history, and vessel location, diameter, and length. The authors present a comparison of proximal and distal anastomotic sites of the facial artery. A chart review of head and neck reconstructions using the facial artery as a recipient vessel over a 7-year period was conducted. The anastomosis site was identified as distal (at the inferior mandible border) or proximal (at the origin of the artery). The distal site was utilized for both defects of the midface/ scalp and of the mandible/neck, while the proximal site was exclusively used for mandible/neck defects. The following complications were included in the analysis: facial nerve injury, surgical site infection, thrombosis, flap congestion, flap loss, hardware failure, malunion/nonunion, osteomyelitis, sinus/fistula, hematoma, seroma, reoperation, and 90-day mortality. Fifty-four free tissue transfers were performed. The overall complication rate (including major and minor complications) was 53.7%. Anastomosis level did not have a significant impact on complication rate. In addition, there were no significant differences in complication rates for the distal anastomosis site when stratified by defect location. However, obese patients were more likely to have a complication than nonobese patients. This conclusion may reassure surgeons that factors related to anastomosis level, such as vessel diameter and proximity to the zone of injury, have less impact on outcomes than factors like obesity, which may inform preoperative planning, intraoperative decision-making, and postoperative monitoring.

BACKGROUND: Resurfacing of facial and neck defects is challenging due to the unique skin color, texture, and thickness of the region. With the development of microsurgical reconstruction, perforator- free flaps can provide adequate soft tissue. However, despite various modifications, such flaps hardly satisfy cosmetic requirements, due to differences in color and bulkiness. We have used superthin thoracodorsal artery perforator (TDAp) free flaps to overcome these limitations. METHODS: Between January 2012 and January 2020, 15 patients underwent reconstructive procedures for facial and neck soft tissue defects using superthin TDAp free flaps. First a perforator was found above the deep fascia and a flap was elevated over the superficial fascia layer. A process named "pushing with pressure and cutting" was carried out before pedicle ligation until all the superficial fat tissue had been removed except for around the perforator. Patient satisfaction was evaluated using a questionnaire about color, contour, and overall satisfaction a minimum of 12âmonths after surgery. RESULTS: Flap size ranged from 6â×â4âcm to 25â×â14âcm (mean, 126.3âcm2). Final flap thickness ranged from 4 to 6âmm. (mean, 4.97âmm). All flaps survived without any loss and there were no flap-related complications. After a mean follow-up period of 14.4âmonths, patients were satisfied with the aesthetic results, and cervical range of motion increased by 11.25 degree on average in burn scar contracture patients. CONCLUSIONS: The superthin TDAp free flap is an excellent alternative to face and neck resurfacing, providing a large and thin flap with excellent color matching and good vascularity.

BACKGROUND: Care pathways (CPs) offer a proven method of systematically improving patient care. CPs are particularly helpful in complex clinical conditions where variation in care is a problem such as patients undergoing major head and neck resection with free flap reconstruction. Although CPs have been used to manage this patient group, most CPs are implemented as part of relatively short-term quality improvement projects. This paper outlines a detailed methodology for designing and delivering a quality management program sustained for 9 years. METHODS: We describe a change management approach informed by Kotter's "8 Step Process" that provided a useful framework to guide program development and implementation. We then provide a detailed, step by step description of how such a program can be implemented as well as a detailed summary of time and costs for design, implementation and sustainability phases. An approach to design and delivery of a measurement, audit and feedback system is also provided. RESULTS: We present a summary of resources needed to design and implement a head and neck surgery quality management program. The primary result of this study is a design for a sustainable quality management program that can be used to guide and improve care for patients undergoing major head and neck resection with free flap reconstruction. CONCLUSIONS: A change management approach to design and delivery of a head and neck quality management program is practical and feasible.

BACKGROUND: Care pathways (CPs) are helpful in reducing unwanted variation in clinical care. Most studies of CPs show they improve clinical outcomes but there is little known about the long-term impact of CPs as part of a sustained quality management program. Head and neck (HN) surgery with free flap reconstruction is complex, time-consuming and expensive. Complications are common and therefore CPs applied to this patient population are the focus of this paper. In this paper we report outcomes from a 9 year experience designing and using CPs in the management of patients undergoing major head and neck resection with free flap reconstruction. METHODS: The Calgary quality management program and CP design is described the accompanying article. Data from CP managed patients undergoing major HN surgery were prospectively collected and compared to a baseline cohort of patients managed with standard care. Data were retrospectively analyzed and intergroup comparisons were made. RESULTS: Mobilization, decannulation time and hospital length of stay were significantly improved in pathway-managed patients (p = 0.001). Trend analysis showed sustained improvement in key performance indicators including complications. Return to the OR, primarily to assess a compromised flap, is increasing. CONCLUSIONS: Care pathways when deployed as part of an ongoing quality management program are associated with improved clinical outcomes in this complex group of patients.

INTRODUCTION: A knowledge gap exists regarding factors to optimize limb salvage and function following oncologic resection. METHODS: We conducted a retrospective review of all free flaps performed for upper extremity (UE) and lower extremity (LE) salvage from 2000 to 2012. RESULTS: Overall, 220 patients underwent free-flap reconstruction for limb salvage (UE: 64, and LE: 156). Flaps were classified as muscle-only (n = 77), myocutaneous (MC; n = 67), or fasciocutaneous (FC; n = 76). Smoking, diabetes, peripheral vascular disease, and prior chemotherapy or radiation had no impact on complications, while osteomyelitis significantly increased the risk of infection (odds ratio [OR] 19.5, confidence interval [95% CI] 3.77-100.64; p = 0.0004), wound healing complications (OR 7.51, 95% CI 2.21-25.49; p = 0.001), and amputation (OR 4.63, 95% CI 1.41-15.19; p = 0.01). Hardware increased the risk for flap loss (OR 4.92, 95% CI 1.33-18.23; p = 0.017). MC and FC flaps had increased risks for hematoma (p = 0.02) and reoperation for microvascular complications (p = 0.005) but were at lower risk for infection (OR 0.14, 95% CI 0.02-0.87; p = 0.03) compared with muscle-only flaps. There were a total of seven total flap losses (3.2%), with significantly increased risks for MC/FC flaps (OR 2.58, 95% CI 1.06-6.26; p = 0.03). For LE, 103 patients (66.3%) were fully ambulatory, while 23 (14.7%) were ambulatory with assistance (mean Musculoskeletal Tumor Society score (MSTS) 80.2, and Karnofsky score 84.0). For UE, 49 patients (76.6%) were able to perform their activities of daily living independently (mean MSTS 80.2, and Karnofsky score 86.0). Overall, 190 patients (86.4%) were successfully salvaged. CONCLUSIONS: Free flaps can be performed reliably for limb salvage following tumor extirpation. While MC/FC flaps demonstrated improved postoperative function, they were at significantly higher risk for take-backs and total flap loss.

It has been a common practice among the oncologist to reduce the dosage of adjuvant radiotherapy for patients after free jejunal flap reconstruction. The current aims to study potential risk of radiation to the visceral flap and the subsequent oncological outcome. Between 1996 and 2010, consecutive patients with carcinoma of the hypopharynx requiring laryngectomy, circumferential pharyngectomy and post-operative irradiation were recruited. Ninety-six patients were recruited. TNM tumor staging at presentation was: stage II (40.6%), stage III (34.4%) and stage IV (25.0%). Median follow-up period after surgery was 68 months. After tumor ablation, reconstruction was performed using free jejunal flap (60.4%), pectoralis major myocutaneous (PM) flap (31.3%) and free anterolateral thigh (ALT) flap (8.3%). All patients underwent adjuvant radiotherapy within 6.4 weeks after surgery. The mean total dose of radiation given to those receiving cutaneous and jejunal flap reconstruction was 62.2 Gy and 54.8 Gy, respectively. There was no secondary ischaemia or necrosis of the flaps after radiotherapy. The 5-year actuarial loco-regional tumor control for the cutaneous flap and jejunal flap group was: stage II (61 vs. 69%, p = 0.9), stage III (36 vs. 46%, p = 0.2) and stage IV (32 vs. 14%, p = 0.04), respectively. Reduction of radiation dosage in free jejunal group adversely affects the oncological control in stage IV hypopharyngeal carcinoma. In such circumstances, tubed cutaneous flaps are the preferred reconstructive option, so that full-dose radiotherapy can be given.

Full-thickness defects of the nose result in severe aesthetic and functional problems. Nasal alar defects are frequently caused by trauma, surgical resection or congenital deformities, yet an alar defect due to a human bite is quite rarely seen. For a successful alar reconstruction, selected tissue must be similar to nasal structures in texture, color and thickness. The structural similarities between the nasal alae and auricular helices have allowed the use of free helical composite flaps for the repair of nasal defects. In this article, we report a 36-year-old male patient who had a right alar defect caused by a human bite. The defect was successfully reconstructed with a reverse flow superficial temporal vessel based pre-auricular and ascending helical free composite flap. Since the color and the texture of the flap was compatible with the nose integuments, this flap enjoyed of an optimal integration in the central facial area.

BACKGROUND: Designing a reliable fibula flap skin paddle can be challenging because of the lack of information on precise perforator locations. The purpose of this study was to precisely map the perforators and provide a simple and reliable method for skin paddle design. METHODS: Eighty consecutive patients undergoing free fibula flap reconstruction were included in this prospectively designed study. The location, size, and type of perforators were recorded intraoperatively and mapped on the line connecting the fibular head and lateral malleolus. RESULTS: There were 46 male and 34 female patients with a total of 202 perforators. The average length of the fibular head and lateral malleolus line was 36.1 ± 3.4 cm (male patients, 38.2 ± 2.2 cm; female patients, 34.1 ± 2.7 cm). Two discrete groups of perforators could be identified. The proximal perforator was consistently found one-third the length and 1.5 cm posterior to the line. The majority of these perforators (84 percent) were musculocutaneous. The more clinically useful perforators to support a skin paddle are the distal ones over the third quarter of the fibula. One to three distal perforators were consistently present, grouped as perforators A, B, and C at points 0.51, 0.62, and 0.73 along the line, respectively. Perforators were approximately 3.5 cm apart and 2 cm posterior to the line, and the majority (96 percent) were septocutaneous. CONCLUSIONS: Using common anatomical landmarks, a reliable skin paddle can be designed with simplicity and confidence over the third quarter of the fibula. The proximal perforator can be useful as a second skin paddle for through-and-through reconstruction.
