Rates of bone reabsorption and union in mandibular reconstruction using the osteocutaneous radial forearm free flap.

BACKGROUND: Historical concerns over bone resorption and malunion of the osteocutaneous radial forearm free flap (OCRFFF) limited its widespread adoption for head and neck reconstruction, despite lack of outcomes data evaluating this notion. METHODS: A retrospective cohort study was performed including patients 18 years or older who underwent reconstruction of the mandible using an OCRFFF. Linear modeling and logistic regression were used to evaluate the change in bone volume and union over time. RESULTS: One hundred and twenty-one patients were included in the study. A mixed effects linear model incorporating age, sex, treatment type, and number of bone segments did not demonstrate a significant loss of bone volume over time. A logistic regression model identified lack of adjuvant treatment and time to be significantly associated with complete union. CONCLUSION: This study supports that the OCRFFF is a stable form of osseus reconstruction for defects of the head and neck.

Comparison of Modern Rigid Fixation Plating Outcomes for Segmental Mandibular Microvascular Reconstruction.

OBJECTIVES/HYPOTHESIS: New advances in osseous microvascular mandibular rigid fixation are being employed at many institutions. These include standardized prebent/preformed reconstruction plates as well as computer-aided design/computer-aided manufacturing (CAD/CAM) custom plates that are patient specific. Our goal was to assess and compare the outcomes of both of these new technologies when utilized for mandibular microvascular reconstruction. STUDY DESIGN: Retrospective chart review. METHODS: Subjects were categorized into two groups according to their mandibular rigid fixation technique: group 1 = prebent/preformed plates and group 2 = CAD/CAM custom plates. Primary outcome measures were 1) perioperative complications (defined as deep tissue infection, wound dehiscence resulting in bone exposure, and/or plate exposure) and 2) reoperation rates for mandibular hardware failure/explantation. Statistical analysis consisted of χ2 , Fisher exact test, and multivariable regression models. RESULTS: A total of 142 subjects underwent microvascular mandibular reconstruction in a 6-year period. Eighty-nine subjects utilized prebent/preformed plates, and 53 employed CAD/CAM custom plates. Perioperative complications occurred in 32 of 89 (35.9%) subjects with prebent/preformed plates and 11 of 53 (20.7%) subjects using CAD/CAM custom plates. Reoperation requiring hardware explantation occurred in 18 of 89 (20.2%) subjects and three of 53 (5.6%) using CAD/CAM custom plates. Statistical comparison of perioperative complications between the two groups approached significance (P = .0556), and the rate of reoperation was significant favoring CAD/CAM implants (P = .0180). CONCLUSIONS: In our experience, CAD/CAM custom plates utilized for rigid fixation during microvascular mandibular reconstruction demonstrated fewer complications and statistically lower reoperation rates when compared with prebent/preformed plates.

Potent Antitumor Effects of a Combination of Three Nutraceutical Compounds.

Head and neck squamous cell carcinoma (HNSCC) is associated with low survival, and the current aggressive therapies result in high morbidity. Nutraceuticals are dietary compounds with few side effects. However, limited antitumor efficacy has restricted their application for cancer therapy. Here, we examine combining nutraceuticals, establishing a combination therapy that is more potent than any singular component, and delineate the mechanism of action. Three formulations were tested: GZ17-S (combined plant extracts from Arum palaestinum, Peganum harmala and Curcuma longa); GZ17-05.00 (16 synthetic components of GZ17-S); and GZ17-6.02 (3 synthetic components of GZ17S; curcumin, harmine and isovanillin). We tested the formulations on HNSCC proliferation, migration, invasion, angiogenesis, macrophage viability and infiltration into the tumor and tumor apoptosis. GZ17-6.02, the most effective formulation, significantly reduced in vitro assessments of HNSCC progression. When combined with cisplatin, GZ17-6.02 enhanced anti-proliferative effects. Molecular signaling cascades inhibited by GZ17-6.02 include EGFR, ERK1/2, and AKT, and molecular docking analyses demonstrate GZ17-6.02 components bind at distinct binding sites. GZ17-6.02 significantly inhibited growth of HNSCC cell line, patient-derived xenografts, and murine syngeneic tumors in vivo (P < 0.001). We demonstrate GZ17-6.02 as a highly effective plant extract combination and pave the way for future clinical application in HNSCC.

Cancer-Associated Fibroblasts Drive Glycolysis in a Targetable Signaling Loop Implicated in Head and Neck Squamous Cell Carcinoma Progression.

Despite aggressive therapies, head and neck squamous cell carcinoma (HNSCC) is associated with a less than 50% 5-year survival rate. Late-stage HNSCC frequently consists of up to 80% cancer-associated fibroblasts (CAF). We previously reported that CAF-secreted HGF facilitates HNSCC progression; however, very little is known about the role of CAFs in HNSCC metabolism. Here, we demonstrate that CAF-secreted HGF increases extracellular lactate levels in HNSCC via upregulation of glycolysis. CAF-secreted HGF induced basic FGF (bFGF) secretion from HNSCC. CAFs were more efficient than HNSCC in using lactate as a carbon source. HNSCC-secreted bFGF increased mitochondrial oxidative phosphorylation and HGF secretion from CAFs. Combined inhibition of c-Met and FGFR significantly inhibited CAF-induced HNSCC growth in vitro and in vivo (P < 0.001). Our cumulative findings underscore reciprocal signaling between CAF and HNSCC involving bFGF and HGF. This contributes to metabolic symbiosis and a targetable therapeutic axis involving c-Met and FGFR.Significance: HNSCC cancer cells and CAFs have a metabolic relationship where CAFs secrete HGF to induce a glycolytic switch in HNSCC cells and HNSCC cells secrete bFGF to promote lactate consumption by CAFs.

Outcomes after free tissue transfer for composite oral cavity resections involving skin.

BACKGROUND: Resections involving oral cavity mucosa, bone, and skin present a unique challenge. Optimizing outcomes often requires technically demanding reconstruction. The purpose of this study is to evaluate outcomes of several reconstructive approaches for patients with composite through-and-through defects, with a focus on the osteocutaneous radial forearm free flap (RFFF). METHODS: We conducted a retrospective evaluation of the cohort of patients treated for composite through-and-through defects with cutaneous involvement who underwent free flap reconstruction from August 2012 through October 2015. RESULTS: Seventeen patients received a single flap (12 cases of osteocutaneous RFFF), whereas 10 patients underwent a combination of flaps. Complication rates and functional outcomes were favorable in patients who underwent osteocutaneous RFFFs. The supraclavicular artery island flap (SCAIF) was used as a second flap in 3 cases. CONCLUSION: The osteocutaneous RFFF provides a valuable reconstructive option for complex composite resection defects involving skin. When 2 flaps are required, the SCAIF is a viable alternative to a second free flap or pectoralis flap.

Mandibular reconstruction.

Mandibular reconstruction presents unique functional and aesthetic challenges to the reconstructive surgeon. This review will cover current techniques for mandibular reconstruction, including the various plating strategies for rigid fixation, the choice of osseous donor site, and the concurrent reconstruction of associated soft tissue defects. Recent developments and future horizons in mandibular reconstruction including the use of virtual surgical planning and tissue engineering will also be addressed.

Secretory Autophagy in Cancer-Associated Fibroblasts Promotes Head and Neck Cancer Progression and Offers a Novel Therapeutic Target.

Despite therapeutic advancements, there has been little change in the survival of patients with head and neck squamous cell carcinoma (HNSCC). Recent results suggest that cancer-associated fibroblasts (CAF) drive progression of this disease. Here, we report that autophagy is upregulated in HNSCC-associated CAFs, where it is responsible for key pathogenic contributions in this disease. Autophagy is fundamentally involved in cell degradation, but there is emerging evidence that suggests it is also important for cellular secretion. Thus, we hypothesized that autophagy-dependent secretion of tumor-promoting factors by HNSCC-associated CAFs may explain their role in malignant development. In support of this hypothesis, we observed a reduction in CAF-facilitated HNSCC progression after blocking CAF autophagy. Studies of cell growth media conditioned after autophagy blockade revealed levels of secreted IL6, IL8, and other cytokines were modulated by autophagy. Notably, when HNSCC cells were cocultured with normal fibroblasts, they upregulated autophagy through IL6, IL8, and basic fibroblast growth factor. In a mouse xenograft model of HNSCC, pharmacologic inhibition of Vps34, a key mediator of autophagy, enhanced the antitumor efficacy of cisplatin. Our results establish an oncogenic function for secretory autophagy in HNSCC stromal cells that promotes malignant progression. Cancer Res; 77(23); 6679-91. ©2017 AACR.

Expanding the Utilization of the Osteocutaneous Radial Forearm Free Flap beyond Mandibular Reconstruction.

Background The osteocutaneous radial forearm free flap (OCRFFF) for mandibular reconstruction has been well described. Despite this flap's utility in the repair of such defects, the indications for the OCRFFF have continued to expand in recent years. The advantages of the OCRFFF allow for a high degree of versatility in the reconstruction of the various anatomical and aesthetic units of the head and neck. In this review, the authors aim to explore the successful utilization of the OCRFFF beyond the reconstruction of composite mandibular defects. Methods A retrospective chart review was performed. All subjects who underwent OCRFFF reconstruction at a tertiary academic center between January 2004 and December 2014 were identified. A total of six patients undergoing this procedure for indications other than composite mandibular defects of the head and neck were included. Results A total of six patients underwent OCRFFF reconstruction for correction of nonmandibular defects. Flap success was experienced in six of six cases (100%). Indications included midface maxillary reconstruction (N = 2), orbit reconstruction (N = 1), frontal sinus and forehead reconstruction (N = 2), and subglottic stenosis reconstruction (N = 1). There were no immediate perioperative complications. On long-term follow-up, one subject developed a nasocutaneous fistula following radiation and eventually required maxillary hardware removal. Conclusion As a result of its growing role and versatility, the OCRFFF should be incorporated as a multipurpose tool in the armamentarium of reconstructive microvascular surgeons in the repair of composite head and neck defects beyond the mandible.

Revisiting the argument for 1- versus 2-vein outflow in head and neck free tissue transfers: A review of 317 microvascular reconstructions.

BACKGROUND: The purpose of this study was to determine the benefit of 1-vein versus 2-vein outflow in microvascular free tissue transfers. METHODS: A retrospective review reflects the experience of 6 surgeons. Analysis included all patients who underwent reconstruction at a single institution between January 2004 and December 2012. RESULTS: Three hundred nine patients underwent a total of 317 microvascular free flap reconstructions for head and neck defects. Two hundred thirteen of 317 flaps (67.2%) used 1 venous anastomosis and 104 (32.8%) used 2 venous anastomoses. Venous congestion necessitated urgent take back in 37 of 57 patients (64.9%) requiring exploration for perioperative complications. Thirty of 37 flaps (81.1%) with venous congestion had 1 vein anastomosis, whereas 7 (18.9%) had dual vein outflow (p = .03). Overall flap success was 303 of 317 (95.6%), despite an 18.0% (57 of 317) perioperative take back rate. CONCLUSION: Coapting 2 veins was shown to minimize venous congestion. © 2015 Wiley Periodicals, Inc. Head Neck 38: 820-823, 2016.

Evaluation of bone length and number of osteotomies utilizing the osteocutaneous radial forearm free flap for mandible reconstruction: An 8-year review of complications and flap survival.

BACKGROUND: The purpose of this study was to assess the impact of bone harvest length and multiple osteotomies on osteocutaneous radial forearm free flap (RFFF) complication rates. METHODS: A retrospective chart review was conducted for patients undergoing osteocutaneous RFFF reconstruction during an 8-year period. RESULTS: One hundred fifty-five osteocutaneous RFFF 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 it was ≥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, whereas 17 of 155 required more than 1 osteotomy; complications were experienced in 42% (29 of 69) and 47% (8 of 17) of these cases, respectively. CONCLUSION: Osteocutaneous RFFF complication rates were only slightly higher when the bone length was ≥7 cm or when multiple osteotomies were required.

The Role of the Head and Neck Surgeon in the New World of Health Care Reform.

The landscape of health care delivery in the United States is in the midst of irreversible and progressive changes that present tremendous opportunities to do maximal good for patients. Clinicians must embrace this opportunity to ensure this redesign is done properly and to the benefit of patients-not the bottom line of the health system. This sweeping change in health care will also align the benefits of preventive care and public health with the economic health of health systems for the first time. Clinicians will be incentivized to ensure that legislative environment fully supports efforts to create a healthier population-which for the American Head and Neck Society means a reduction or elimination of tobacco use and widespread HPV vaccination of children.

A longitudinal study of emotional intelligence training for otolaryngology residents and faculty.

IMPORTANCE: Emotions underlie and influence physician communications and relationships with patients and colleagues. Training programs to enhance emotional attunement, or emotional intelligence (EI), for physicians and assess training effects are scarce. OBJECTIVE: To assess whether an EI training program for otolaryngology residents and faculty affects patient satisfaction. DESIGN, SETTING, AND PARTICIPANTS: Prospective longitudinal, cohort study of physician residents and faculty in an EI training program at the Department of Otolaryngology, University of Kansas Medical Center, with annual training from 2005 to 2011. INTERVENTIONS: Three levels of interventions included 4 years of repeated EI assessment, 7 years of highly interactive EI training with high-risk/high-stress simulations, and ongoing modeling and mentoring of EI skills by faculty. MAIN OUTCOMES AND MEASURES: Four levels of outcome of the EI training were assessed with the following questions: Did participants enjoy the program? Could they apply the training to their practice? Did it change their behavior? Did it affect patient satisfaction? The Emotional Quotient Inventory (EQ-i) was administered to faculty and residents, and the Press Ganey Patient Satisfaction Survey was completed by patients. RESULTS: Ninety-seven percent of participants (103 of 106) reported that they enjoyed the programs, and 98% (104 of 106) reported that they have or could have applied what they learned. Participants demonstrated improvement in mean EQ-i scores from 102.19 (baseline/pretraining) to 107.29 (posttraining and assessment 1 year later; change, 6.71; 95% CI, 3.44-9.98). This increase was sustained in successive years, and these results were supported with linear growth curve analysis. The total department mean EQ-i score in pretraining year 2005 was 104.29 ("average" range), with posttraining scores in the "high average" range (112.46 in 2006, 111.67 in 2007, and 113.15 in 2008). An increase in EQ-i scores and EI training corresponded with an increase in patient satisfaction scores. Percentile rank patient satisfaction scores before EI training ranged from 85% to 90%; after training, scores ranged from 92% to 99%. CONCLUSIONS AND RELEVANCE: Emotional intelligence training positively influences patient satisfaction and may enhance medical education and health care outcome.

Factors influencing morbidity after surgical management of malignant thyroid disease.

OBJECTIVES: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Ultrasound for localization in primary hyperparathyroidism.

OBJECTIVE: To evaluate the capability of ultrasound for preoperative localization in primary hyperparathyroidism. STUDY DESIGN: Prospective study. SETTING: Multi-institutional Midwest Head and Neck Cancer Consortium. SUBJECTS AND METHODS: Two hundred twenty patients who underwent preoperative localization and had parathyroid surgery were evaluated. The findings of preoperative localization studies were correlated with surgical findings. RESULTS: Preoperative ultrasonography, sestamibi scintigraphy, or both were obtained in 77%, 93%, and 69% of the patients, respectively. Preoperative ultrasonography and sestamibi scintigraphy localized an abnormality in 71% and 79% of patients, respectively. At the time of surgery, the localization by ultrasound was accurate in 82%. The accuracy of localization was similar for sestamibi scintigraphy (85%). In patients with inaccurate ultrasound localization, the sestamibi scintigraphy correctly identified the site of disease in only 45%. In patients with a nonlocalizing ultrasound, sestamibi scintigraphy was able to localize disease in only 47%, with 2 being in the mediastinum. CONCLUSIONS: Ultrasonography is an acceptable initial localization study for patients with primary hyperparathyroidism. In patients with nonlocalizing ultrasound, sestamibi scintigraphy should be obtained, but can be expected to detect an abnormality in less than 50% of patients.

Outcomes of the osteocutaneous radial forearm free flap for mandibular reconstruction.

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.

Identifying incident oral and pharyngeal cancer cases using Medicare claims.

BACKGROUND: Baseline and trend data for oral and pharyngeal cancer incidence is limited. A new algorithm was derived using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database to create an algorithm to identify incident cases of oral and pharyngeal cancer using Medicare claims. METHODS: Using a split-sample approach, Medicare claims' procedure and diagnosis codes were used to generate a new algorithm to identify oral and pharyngeal cancer cases and validate its operating characteristics. RESULTS: The algorithm had high sensitivity (95%) and specificity (97%), which varied little by age group, sex, and race and ethnicity. CONCLUSION: Examples of the utility of this algorithm and its operating characteristics include using it to derive baseline and trend estimates of oral and pharyngeal cancer incidence. Such measures could be used to provide incidence estimates where they are lacking or to serve as comparator estimates for tumor registries.

Functional swallowing outcomes following transoral robotic surgery vs primary chemoradiotherapy in patients with advanced-stage oropharynx and supraglottis cancers.

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.

Chemotherapy in head and neck cancer: clinical predictors of tolerance and outcomes.

BACKGROUND: The addition of chemotherapy is more efficacious than radiation alone in the treatment of head and neck cancer (HNC). However, little data are available regarding the best chemotherapy agent and dosing, or factors associated with chemotherapy compliance. METHODS: Retrospective review of all HNC patients receiving combined chemotherapy and radiotherapy at the University of Kansas Medical Center between 1994 and 2006. A total of 172 patients were analyzed in this report. RESULTS: A total of 37% of patients were able to complete the entire chemotherapy regimen as intended. Multiple factors were examined in relation to chemotherapy completion and clinical outcome. Factors associated with not being able to complete chemotherapy on Cox regression analysis include use of a platinum agent and older age at diagnosis. No chemotherapy-related variables were prognostic for overall survival or disease-free survival. CONCLUSION: Factors associated with reduced chemotherapy compliance include older age and cisplatin agent. None of the chemotherapy characteristics (agent, total dose, and schedule) were associated with outcome.

Safe osteocutaneous radial forearm flap harvest with prophylactic internal fixation.

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.

Sinonasal adenoid cystic carcinoma presenting as an orbital mass.

A 61-year-old man with a history of sinus polyposis and prior sinus surgery presented with left-sided retrobulbar pain and headache. He was found to have left-sided proptosis, and imaging studies showed a large left medial orbital soft-tissue mass. Incisional biopsy revealed adenoid cystic carcinoma. Further evaluation revealed extensive sinonasal adenoid cystic carcinoma. The patient underwent en bloc maxillectomy with orbital exenteration and partial rhinectomy, followed by radiation therapy. The medial orbit is an unusual location for adenoid cystic carcinoma, which the authors believe was a secondary manifestation due to perineural spread from the sinuses via the ethmoidal nerves. Adenoid cystic carcinoma should be included in the differential diagnosis of tumors of the medial orbit, especially if there is a history of sinonasal disease.
