    ABSTRACT: Purpose: Vascular compromise after microvascular head and neck reconstruction is rare. When it does occur venous problems are most likely to blame. The benefit of utilizing one versus two veins for outflow is debatable in the literature1-4. We hypothesize that performing dual vein outflow improves flap viability and reduces peri-operative complications in head and neck microvascular reconstruction. Methods: A retrospective chart review was performed. All subjects who underwent head and neck microvascular reconstruction at the University of Kansas Medical Center between January 2004 and December 2012 were included. Outcomes of flaps utilizing one and two vein outflow were compared. First peri-operative vascular compromise was compared between the two groups. Secondly, flap complications including hematoma, wound healing problems/dehiscence/fistula, and partial or complete flap failure were compared. A Chi-square test was used to compare both groups. Results: In this study, 309 subjects underwent a total of 317 microvascular free flap reconstructions of the head and neck. 213 of the 317 (67.2%) flaps utilized one vein outflow and 104 (32.8%) employed dual vein outflow. 57 of 317 (18%) flaps required urgent exploration for peri-operative vascular compromise. Of these 57 flaps, 41 (71.9%) had only one venous anastomosis while 16 (28.1%) had two venous anastomoses. Venous congestion was the reason for urgent exploration in 37 of the 57 (64.9%) subjects. 30 of the 37 (81.1%) flaps with venous congestion had one vein anastomosis and 7 of the 37 (18.9%) had dual vein outflow (p = 0.03). The incidence of flap complications included 38 of 213 (17.8%) in the single vein group and 15 of 104 (14.4%) in the group utilizing dual venous outflow (p = 0.44). The overall flap success rate was 303 out of 317 (95.6%) flaps. Interestingly, 12 of 14 (85.7%) flap failures had a single vein anastomosis while 2 of 14 (14.3%) flap failures utilized a dual vein outflow (p = 0.15). Conclusion: Our experience demonstrates a statistically significant decrease in re-exploration for venous congestion when dual vein outflow is utilized compared with single vein anastomosis. The incidence of overall flap complications and flap failure was lower although not significant when dual vein outflow was utilized. Based on these findings, when feasible, coapting two veins should be considered in any head and neck microvascular reconstruction.

    ABSTRACT: Background. The purpose of this study was to assess the impact of bone harvest length and multiple osteotomies on osteocutaneous radial forearm free flap (OCRFFF) complication rates.Methods. A retrospective chart review was conducted for patients undergoing OCRFFF reconstruction during an 8-year period.Results. 155 OCRFFF procedures were performed. Recipient-site flap complications were 18 of 55 (32.7%) when bone harvest length was less than 7 cm and 40 of 100 (40.0%) when ≥ 7 cm. No osteotomies were performed in 69 of 155 cases with a corresponding complication rate of 30.4% (21 of 69). One osteotomy was utilized in 69 of 155 flaps while 17 of 155 required more than one osteotomy; complications were experienced in 42% (29 of 69) and 47% (8 of 17) of these cases, respectively.Conclusion. OCRFFF complication rates were only slightly higher when bone length was ≥ 7 cm or when multiple osteotomies were required. Head Neck, 2014

    ABSTRACT: We performed a retrospective study of cases from 2005 to 2010 at an academic tertiary care center to analyze the factors that influence morbidity in surgical management of thyroid malignancy. The rates of recurrent laryngeal nerve (RLN) injury and hypoparathyroidism (HPT) were analyzed in the entire cohort. The comparison groups were 1) primary surgery versus revision; 2) total thyroidectomy versus total thyroidectomy combined with neck node dissection; and 3) two groups defined by surgical technique according to the RLN approach: group 1, in which the RLN was identified inferiorly in the tracheoesophageal groove, and group 2, in which the RLN was identified near the cricothyroid joint point of entry. We reviewed 308 patients who underwent surgery for thyroid cancer. Thirty-six (11.7%) had temporary HPT, and 8 (2.6%) had permanent HPT. Of a total of 586 RLNs at risk, 16 (2.7%) had temporary damage and 2 (0.3%) had permanent damage. The incidences of temporary RLN injury significantly differed between the primary-surgery and revision-surgery groups (2.5% versus 15.6%; p = 0.001), and also between the groups with total thyroidectomy and thyroidectomy with neck dissection (1.2% versus 7.8%; p = 0.027). The incidences of temporary HPT were significantly different between the groups with primary surgery and revision surgery (6.6% versus 31.3%; p = 0.001), between the groups with total thyroidectomy and total thyroidectomy with neck dissection (4.7% versus 15.6%; p = 0.009), and between group 1 and group 2 (surgical technique in terms of RLN approach; 8.2% versus 17.9%; p = 0.011). Permanent HPT and permanent RLN injury both occurred rarely in this cohort, with no significant differences among comparison groups. Our study shows a higher incidence of temporary RLN injury and teniporary HPT in revision surgery cases and in total thyroidectomy with neck dissection. Temporary HPT was significantly more common when the RLN was identified near the cricothyroid joint.

    ABSTRACT: IMPORTANCE Limited donor and recipient site complications support the osteocutaneous radial forearm free flap (OCRFFF) for mandibular reconstruction as a useful option for single-stage mandibular reconstruction. OBJECTIVE To examine and report long-term outcomes and complications at the donor and recipient sites for patients undergoing the OCRFFF for mandibular reconstruction. DESIGN Retrospective review. SETTING Academic, tertiary care medical center. PATIENTS The study population comprised 167 consecutive patients who underwent single-staged mandibular reconstruction with an OCRFFF. MEAN OUTCOME MEASURES Rates of complications at the donor and recipient sites. RESULTS The mean patient age was 61 years (range, 20-93 years). Men compromised 68% of the population. Follow-up interval ranged from 2 to 99 months (mean, 25.9 months). The median length of bone harvested was 7 cm (range, 2.5-12.0 cm). Prophylactic plating was completed for each of the radii at the time of harvest. Donor site complications included radial fracture (1 patient [0.5%]), tendon exposure (47 patients [28%]), and donor hand weakness or numbness (13 patients [9%]). Recipient site complications included mandible hardware exposure (29 patients [17%]), mandible nonunion or malunion (4 patients [2%]), and mandible bone or hardware fracture (4 patients [2%]). Using regression analysis, we found that patients were 1.3 times more likely to have plate exposure for every increase of 1 cm of bone harvest length; this was statistically significant (P = .04). CONCLUSIONS AND RELEVANCE This is the largest single study reporting outcomes and complications for patients undergoing OCRFFF for mandibular reconstruction. Prophylactic plating of the donor radius has nearly eliminated the risk of pathologic radial bone fractures. Limited long-term donor and recipient site complications support the use of this flap for single-stage mandibular reconstruction.

    ABSTRACT: OBJECTIVES To evaluate functional swallowing outcomes in patients undergoing transoral robotic surgery vs primary chemoradiotherapy for the management of advanced-stage oropharynx and supraglottis cancers. DESIGN Prospective nonrandomized clinical trial. SETTING Academic research. PATIENTS We studied 40 patients with stage III or stage IVA oropharynx and supraglottis squamous cell carcinoma. Group 1 comprised 20 patients who received transoral robotic surgery with adjuvant therapy, while group 2 comprised 20 patients whose disease was managed by primary chemoradiotherapy. MAIN OUTCOME MEASURES Patients completed the M. D. Anderson Dysphagia Inventory (MDADI) before treatment and then at follow-up visits at 3, 6, and 12 months. The MDADI scores were analyzed and compared. RESULTS The median follow-up period for both groups was 14 months (range, 12-16 months). When comparing the median MDADI scores between group 1 and group 2, we found no statistically significant differences before treatment or at the 3-month follow-up visit. However, this difference was significant at the posttreatment visits at 6 months (P = .004) and 12 months (P = .006), where group 1 had better swallowing MDADI scores. We also found significant differences in swallowing MDADI scores between the groups at the 6-month posttreatment visit for patients with T1, T2, and T3 disease and at the 12-month follow-up visit for patients with T2 and T3 disease, where group 1 had significantly better MDADI scores. Comparing tumor subsites, group 1 fared significantly better at the follow-up visits at 6 months (P = .02) and 12 months (P = .04) for patients with primary tumor at the tonsil. Compared with group 2, group 1 patients having base of tongue cancers exhibited significantly better swallowing MDADI scores at the 6-month follow-up visit (P = .02), and group 1 patients having lateral oropharynx disease had significantly better swallowing MDADI scores at the 12-month follow-up visit (P = .04). CONCLUSION Advanced-stage oropharynx and supraglottis cancers managed by transoral robotic surgery with adjuvant therapy resulted in significantly better swallowing MDADI outcomes at the follow-up visits at 6 and 12 months compared with tumors treated by primary chemoradiotherapy.

    ABSTRACT: The Accreditation Council for Graduate Medical Education (ACGME) requires residency programs to meet and demonstrate outcomes across 6 competencies. Measuring residents' competency in practice-based learning and improvement (PBLI) is particularly challenging. We developed an educational tool to meet ACGME requirements for PBLI. The PBLI template helped programs document quality improvement (QI) projects and supported increased scholarly activity surrounding PBLI learning. We reviewed program requirements for 43 residency and fellowship programs and identified specific PBLI requirements for QI activities. We also examined ACGME Program Information Form responses on PBLI core competency questions surrounding QI projects for program sites visited in 2008-2009. Data were integrated by a multidisciplinary committee to develop a peer-protected PBLI template guiding programs through process, documentation, and evaluation of QI projects. All steps were reviewed and approved through our GME Committee structure. An electronic template, companion checklist, and evaluation form were developed using identified project characteristics to guide programs through the PBLI process and facilitate documentation and evaluation of the process. During a 24 month period, 27 programs have completed PBLI projects, and 15 have reviewed the template with their education committees, but have not initiated projects using the template. The development of the tool generated program leaders' support because the tool enhanced the ability to meet program-specific objectives. The peer-protected status of this document for confidentiality and from discovery has been beneficial for program usage. The document aggregates data on PBLI and QI initiatives, offers opportunities to increase scholarship in QI, and meets the ACGME goal of linking measures to outcomes important to meeting accreditation requirements at the program and institutional level.

    ABSTRACT: We studied the efficacy of prophylactic plate fixation technique and a modified harvest of the osteocutaneous radial forearm free flap (OCRFFF) to minimize the incidence of postoperative donor radius pathological fracture. We retrospectively studied of the first 70 consecutive patients undergoing OCRFFF harvest by the University of Kansas Head and Neck Microvascular Reconstruction Team. Mean follow-up was 13 months. One of two patients undergoing OCRFFF harvest without prophylactic fixation developed a pathological radius fracture. The 68 subsequent OCRFFF patients underwent prophylactic fixation of the donor radius, and none developed a symptomatic radius fracture. Five of 68 patients did have a radiographically visible fracture requiring no intervention. The plate fixation technique was further modified to exclude monocortical screws in the radius bone donor defect (subsequent 39 patients), without any further fractures detected. One patient required forearm hardware removal for an attritional extensor tendon tear. The described modified OCRFFF harvest and prophylactic plate fixation technique may eliminate postoperative pathological fracture of the donor radius. Donor morbidity is similar to that of the fasciocutaneous radial forearm free flap , affording safe use of OCRFFF in head and neck reconstruction.

    ABSTRACT: To compare the efficacy of acellular dermal matrix (ADM) and split thickness skin grafts (STSG) in oral cavity reconstruction. Prospective cohort study. Thirty-four patients were included in this study (ADM, n = 22; STSG, n = 12). Evaluation for patient demographics, graft site, graft contracture, and functional status as defined by the EORTC QLQ-C30 and the H&N35 questionnaires. A subgroup of patients underwent graft site biopsy for histological analysis. A cost estimate of both procedures was also performed. Patient groups were similar in age, sex, race, smoking exposure, and site grafted. More patients were treated with radiation therapy (pre- or postoperative) in the ADM group (45%) compared to the STSG group (17%). Graft failure rate was higher in the ADM group (14% vs. 0%), and both groups had similar estimated graft contraction. The quality of life survey results favored the ADM group, but only the category of trouble with social eating was statistically significant (P = .03). Radiation therapy had a significantly negative impact for both ADM and STSG. Histology demonstrated increased inflammation, fibrosis, and elastic fibers in the STSG group. The cost of the STSG was 3.5 times higher than the ADM group. Acellular dermis grafting for reconstruction of the oral cavity offers several advantages over STSG, including the lack of donor site morbidity, lower cost, a natural appearing mucosal surface, and comparable if not superior functional status. Lower graft survival rates for ADM in the setting of prior radiation and with thicker graft material was encountered.

    ABSTRACT: Technical skill is only one component of overall surgical competency, but it has been one of the most difficult to measure. Assessment methods are currently subjective and unreliable, and include techniques such as operative logs, end-of-rotation global assessments, and direct observation without criteria. Newer objective methods of technical skill assessment are being developed and undergoing rigorous validation, including methods such as direct observation with criteria, final product analysis, and hand-motion analysis. Following the example set in other fields in which high-stakes assessment is paramount, such as in aviation, virtual reality simulators have been introduced to surgical competency assessment and training. Significant work remains to integrate these assessments into both training programs and practice and to demonstrate a resultant improvement in surgical outcome.

    ABSTRACT: The osteocutaneous radial forearm free flap (ORFFF) is an ideal source of vascularized bone and soft tissue for repair of defects in reconstructions of the head and neck. However, studies have revealed significant donor site morbidity, decreasing the popularity of this procedure. We have previously reported our technique of prophylactic internal fixation of the radius at the time of graft harvest, developed to decrease donor radius fractures. This is a retrospective radiographic review of our long-term radius donor site morbidity. Forearm radiographs more than 3 years after ORFFF with prophylactic plating were evaluated and compared with prior postoperative films. No donor radius fractures were identified. All radiographs exhibited remodeling and/or reconstitution of donor radii. There was no evidence of implant failure, loosening, or surrounding osteopenia. This study lends further credibility to the ORFFF, when prophylactically plated, as a safe and reliable source of vascularized bone and soft tissue for reconstructive procedures.

    ABSTRACT: We sought to evaluate the functional and aesthetic outcomes of immediate facial reconstruction with a Gore-Tex (expanded polytetrofluoroethylene) sling in irradiated patients undergoing large head and neck tumor extirpation with facial nerve resection. We conducted a retrospective study of 17 patients at two academic institutions who underwent extirpative surgery with immediate Gore-Tex sling reconstruction and completed radiotherapy. Functional and aesthetic results were evaluated at three intervals. All patients had excellent immediate results and good or excellent intermediate-term results. At long-term follow-up, results were good to excellent in 47% and unacceptable in 35% of patients. In irradiated patients undergoing total parotidectomy with immediate facial reconstruction using Gore-Tex slings, early results are excellent, but there is a high incidence of major wound complications and unacceptable results in long-term follow-up. There is a high rate of late complications associated with immediate facial reconstruction with Gore-Tex slings in irradiated patients.

    ABSTRACT: Static facial suspension (SFS) continues to play a role for rehabilitation in patients with facial paralysis. We perform SFS almost exclusively with a suture technique in our practice. Monofilament polypropylene suture (Prolene) is commonly used for SFS, but we have witnessed occasional failure and some stretching with this material. The purpose of this study was to establish and compare the biomechanical properties of 3 suture types-polypropylene, polybutilate-coated braided polyester (PBCP) (Ethibond Excel), and braided polyester impregnated with polytetrafluoroethylene (PIP) (Tevdek)-to assess their suitability for SFS. Six samples of 0, 2-0, and 3-0 polypropylene, PBCP, and PIP were tested. The mean load to failure was calculated for each suture type. Stiffness and elongation at specific loads were calculated to compare stretch between materials. The load to failure of PBCP and PIP was significantly greater than that for polypropylene for all suture sizes. In addition, PBCP and PIP had significantly less elongation than did polypropylene at clinically relevant loads. Both PBCP and PIP had superior load-bearing properties and decreased stretch when compared with polypropylene. These properties suggest that, for SFS with suture, use of PBCP or PIP may reduce the incidence of breakage and elongation, improving outcomes.

    ABSTRACT: To evaluate the role of the osteocutaneous radial forearm free flap (OCRFFF) in the treatment of mandibular osteoradionecrosis (ORN). Retrospective case review of patients who underwent OCRFFF oromandibular reconstruction after resection of nonviable tissue at an academic tertiary care center because of ORN. Patients with reconstructions other than OCRFFF were excluded from this study. Nine patients underwent a composite oromandibular resection for ORN with a reconstruction using an OCRFFF between April 1998 and February 2003. All patients had failed previous less aggressive surgical and medical management of the ORN. Mean follow-up was 36 months (range, 14-67 months). There were no flap failures or significant immediate postoperative or long-term complications observed. All patients had successful restoration of mandibular integrity and continuity, with 100% success rate of stabilization of ORN. All patients were able to tolerate PO diet, with only one third having to supplement their diet with gastrostomy feedings, compared with 89% gastrostomy dependence preoperatively. Primary or adjuvant radiotherapy for head and neck malignancies can result in ORN of the mandible. This difficult problem often requires surgical intervention. In our experience, the OCRFFF can be successfully used for oromandibular reconstruction, even in the setting of the heavily radiated tissue with excellent postoperative outcomes. This is the first study that demonstrates the efficacy of the OCRFFF as a treatment of mandibular ORN.

    ABSTRACT: To compare our experience with the osteocutaneous radial forearm free flap (group 1) (n = 108) with other commonly used osteocutaneous free flaps (group 2) (n = 56) such as the fibula and scapula in single-stage oromandibular reconstruction. Retrospective case review. Tertiary-care academic medical center. One hundred sixty-three consecutive patients who underwent 164 mandibular reconstructions with osteocutaneous free flaps. Assessment of preoperative and intraoperative variables for both groups. We compared recipient-site complication rate, intensive care unit stay, total hospital stay, and postoperative function. The most common donor site used was the radius (n = 108 [66%]), followed by the fibula (n = 36 [22%]) and scapula (n = 20 [12%]). Mean follow-up was 29 months (range, 1-116 months). Group 2 patients had larger soft tissue and/or bony defects. Surgical and medical complication rates and major donor site morbidity in group 1 were similar or better when compared with those in group 2. The lengths of the intensive care unit (4 vs 7 days; P = .009) and hospital stays (13 vs 15 days; P = .06) were shorter in group 1. Although the microvascular success rate was similar in both groups, the local wound complication rate was significantly better for group 1. The difference for the length of intensive care unit stay was statistically significant and potentially amounts to more than 6000 dollars of savings. Functional outcomes, including the ability to tolerate oral diet, tracheostomy presence, and dental rehabilitation, were similar between the groups. The primary site long-term morbidity, donor site morbidity, and postoperative function of osteocutaneous radial forearm free flaps are comparable to those of other commonly used osteocutaneous free flaps such as the fibula and scapula when used in single-stage oromandibular reconstruction.

    ABSTRACT: To review our experience with 2.0-mm locking reconstruction plate (LRP) system for patients requiring oromandibular reconstruction. Retrospective case review of 43 consecutive patients who underwent mandibular composite resection with immediate reconstruction. Tertiary care center. Forty-three patients underwent oromandibular reconstruction with the 2.0-mm mandibular LRP system and free flaps containing vascularized bone. Mean follow-up was 11 months. There were no intraoperative difficulties utilizing this system. Two (5%) patients had partial fasciocutaneous flap loss resulting in plate exposure. There were no instances of plate fracture or complications requiring plate removal to date. 2.0-mm LRP mandibular system is reliable even in the setting of previous or adjuvant radiation therapy. Its technical ease of application, contouring malleability, and very low profile have proven to be advantageous in oromandibular reconstruction. No previous descriptions of use of the 2.0-mm LRP in combination with osteocutaneous free flaps for mandibular reconstruction are found in the literature. EBM rating: C.

    ABSTRACT: Our goal was to evaluate our experience with radiation-induced malignancy (RIM), compare that experience to the literature, and review treatment modalities. The setting is the University of Kansas Medical Center. A retrospective review was performed to identify patients with RIM. Patients were included if they met the criteria for RIM as delineated in the literature. Thirteen patients met the criteria for RIM. The mean latency period was 22 years. Sarcomas were the most common type of RIM and the paranasal sinuses were the most common location. Surgical resection was our treatment of choice. Our patient series differs from previous reports in that sarcomas were the predominating RIM and the paranasal sinuses were the most common location. We noted a shorter latency period than has been previously published. Surgical excision is the treatment of choice. EBM rating: C.
