Positive Trends in Racial Disparities for Head and Neck Microvascular Reconstructive Surgery.

OBJECTIVE: To evaluate national trends in racial disparities for patients undergoing head and neck reconstructive surgery. METHODS: Retrospective analysis using the 2008 to 2021 American College of Surgeons National Surgical Quality Improvement Program database. Patients receiving microvascular free tissue transfer were eligible for inclusion. Pediatric patients and those treated by non-otolaryngologists were excluded. Outcomes were analyzed with univariate and multivariable models. RESULTS: A total of 5831 head and neck free flap cases were analyzed, 4869 (83.5%) were White, 560 (9.6%) were Black or African American, and 402 (6.9%) were Asian, Native American, or other groups (ANAOG). The proportion of Black or African American patients and ANAOG patients undergoing free tissue transfer increased significantly over the time period (p = 0.047 and p = 0.010, respectively). However, there was a downtrend that started around 2017. In a multivariable model, Black or African American race was not associated with readmission (OR = 0.99 [95% CI 0.74, 1.31], p > 0.05), returning to the operating room (OR = 1.20 [95% CI 0.96, 1.49], p > 0.05), or any post-operative complication (OR = 0.83 [95% CI 0.68, 1.01], p > 0.05). There were also no significant associations found in the ANAOG population on multivariate analysis (p > 0.05 for all). CONCLUSION: The percentage of free tissue transfer performed in patients from minority backgrounds with head and neck cancer has been increasing in the United States. Outcomes after head and neck microvascular reconstruction are similar when stratified by race. However, racial disparities remain and further work is necessary to reduce these disparities.

Analysis of antibiotic resistant infections associated with hirudotherapy.

OBJECTIVE: Given rising concern regarding antibiotic resistance, our objective was to evaluate antibiotic-resistant infections following leech therapy and to characterize the use of prophylactic antibiotics. METHODS: All reports of adverse events involving hirudotherapy (product code "NRN") were retrieved from the U.S. Food and Drug Administration MAUDE database between 2012 and 2021. Antibiotic resistance was defined by bacterial culture or infection after antibiotic administration. RESULTS: Nineteen cases of antibiotic resistance involving hirudotherapy were identified. Only three cases of antibiotic resistance were discovered on routine testing and the remaining 16 cases were associated with patient injury. Positive blood cultures or fever were present in 26.3 % (n = 5) of cases. Cultures of the infection grew Aeromonas hydrophilia (n = 13; 68.4 %), Vibrio vulnificus (n = 3; 15.8 %), Pseudomonas aeruginosa (n = 2; 10.5 %), and Proteus vulgaris (n = 1; 5.3 %). There were nine (47.4 %) multi-drug resistant infections. Infection was most commonly resistant to fluoroquinolones (n = 9; 47.4 %), trimethoprim-sulfamethoxazole (n = 9; 47.4 %) and ertapenem (n = 4; 21.1 %). CONCLUSION: Antibiotic-resistant infections involving hirudotherapy are frequently resistant to multiple drugs, including fluoroquinolones and trimethoprim-sulfamethoxazole. Resistance to ertapenem, a drug of last resort, was also documented. The findings presented in this study support growing literature that the trend in multi-drug resistance is more severe than previously reported.

Patterns of failure after salvage head and neck surgery.

BACKGROUND: Advancements in immunotherapy for recurrent head and neck cancer have necessitated a better understanding of salvage surgical outcomes. This study aimed to determine patterns of failure following salvage head and neck surgery. METHODS: A retrospective cohort study was conducted of 280 patients who underwent salvage surgery for recurrent mucosal squamous cell carcinoma from 1997 to 2018. Cumulative incidence was calculated using the nonparametric Aalen-Johansen estimator. Time to recurrence (TTR) and overall survival (OS) were estimated using the Kaplan-Meier method and multivariable Cox proportional hazard models were used to evaluate associated factors. RESULTS: The 2 and 5-year cumulative incidence rates of second recurrence were 48.3 % (95 % CI 42.4-54.3) and 54.9 % (95 % CI 48.9-60.8), respectively. At 5 years, second locoregional recurrence was twice as common as distant recurrence (41.5 % [95 % CI 35.6-47.4] vs. 21.7 % [95 % CI 16.8-26.6]). The median TTR was 21.1 months (95 % CI 4.4-34.8), which varied by site (38.2 larynx/hypopharynx, 13.9 oral cavity, 8.3 sinonasal, and 7.8 oropharynx, P=.0001). The median OS was 32.1 months (95 % CI 24.1-47.6) and was worse for patients who were Black (hazard ratio [HR] 2.15, 95 % CI 1.19-3.9), current smokers (HR 2.73, 95 % CI 1.53-4.88), former smokers (HR 2.00, 95 % CI 1.19-3.35), ≥ 60 years of age (HR 1.41, 95 % CI 1.01-1.97), or received multimodal primary therapy (HR 1.98, 95 % CI 1.26-3.13). CONCLUSION: Rates of recurrence and mortality after salvage surgery were poor but worse for patients who were Black, older, smoked, had initial multimodal therapy, or had sinonasal or oropharyngeal cancers.

Masseteric Atrophy Following Masseteric Nerve Transfer: Radiographic Findings of Asymmetry in the Paralyzed Face?

OBJECTIVES: To characterize the effect of facial reanimation using masseteric nerve transfer on the masseter muscle itself, examining whether there is any demonstrable atrophy postoperatively. METHODS: Electronic medical records of adult patients who underwent facial reanimation using masseteric nerve transfer at our institution over a 15-year period were reviewed. To account for the impact of postoperative radiation, randomly selected patients who underwent radical parotidectomy without nerve transfer and received postoperative radiation served as controls in a 1:1 fashion against those who underwent masseteric nerve transfer with postoperative radiation. RESULTS: Twenty patients were identified who underwent masseteric nerve transfer and had sufficient pre- and postoperative imaging to assess masseter volume (mean age 58.2, 60% female). Of the four patients who did not receive postoperative radiation, each demonstrated masseteric atrophy on the side of their nerve transfer, with a mean reduction in masseter volume of 20.6%. The remaining 16 patients were included in the case-control analysis accounting for radiation. When compared with controls, those in the study group were found to have a statistically significant difference in atrophy (p = 0.0047) and total volume loss (p = 0.0002). The overall reduction in masseter volume in the study group was significantly higher compared with the control group, at 41.7% and 16.6%, respectively (p = 0.0001). CONCLUSION: Facial reanimation utilizing masseteric nerve transfer appears to result in atrophy of the denervated masseter when compared with the contralateral muscle. This volume deficit may lead to further facial asymmetry for patients undergoing comprehensive reanimation surgery. LEVEL OF EVIDENCE: 3 Laryngoscope, 2024.

Prevention and Management of Osteoradionecrosis in Patients With Head and Neck Cancer Treated With Radiation Therapy: ISOO-MASCC-ASCO Guideline.

PURPOSE: To provide evidence-based recommendations for prevention and management of osteoradionecrosis (ORN) of the jaw secondary to head and neck radiation therapy in patients with cancer. METHODS: The International Society of Oral Oncology-Multinational Association for Supportive Care in Cancer (ISOO-MASCC) and ASCO convened a multidisciplinary Expert Panel to evaluate the evidence and formulate recommendations. PubMed, EMBASE, and Cochrane Library databases were searched for randomized controlled trials and observational studies, published between January 1, 2009, and December 1, 2023. The guideline also incorporated systematic reviews conducted by ISOO-MASCC, which included studies published from January 1, 1990, through December 31, 2008. RESULTS: A total of 1,539 publications were initially identified. There were 487 duplicate publications, resulting in 1,052 studies screened by abstract, 104 screened by full text, and 80 included for systematic review evaluation. RECOMMENDATIONS: Due to limitations of available evidence, the guideline relied on informal consensus for some recommendations. Recommendations that were deemed evidence-based with strong evidence by the Expert Panel were those pertaining to best practices in prevention of ORN and surgical management. No recommendation was possible for the utilization of leukocyte- and platelet-rich fibrin or photobiomodulation for prevention of ORN. The use of hyperbaric oxygen in prevention and management of ORN remains largely unjustified, with limited evidence to support its practice.Additional information is available at www.asco.org/head-neck-cancer-guidelines.

Subjective and objective assessments of executive functions are independently predictive of aggressive tendencies in patients with substance use disorder.

BACKGROUND AND AIMS: Impairments in executive functions have been found to influence violent behavior. Executive functions are crucial in the treatment of patients with substance use disorders because substance use generally impairs cognitive processes and is therefore detrimental for executive functions thereby reducing control of behavior and thus of consumption impulses. We studied correlations between subjective, i.e. self-report, and objective, i.e. behavior-based, assessment of executive functions and the predictive validity of these measures for aggression in patients with substance use disorder. METHODS: The study included 64 patients with a diagnosed substance use disorder who were convicted according to the German Criminal Code for crimes they committed in the context of their disorder and were therefore in treatment in forensic psychiatric departments in Germany. Multiple self-report and behavior-based instruments were used to assess executive functions, appetitive and facilitative aggression as well as clinical and sociodemographic variables. RESULTS: Participants showed impaired executive functions, and measures of executive functions predicted aggressive tendencies and violent offenses. Despite ecological validity of the findings, the subjective and objective assessments of executive functions did not correlate with each other, which corroborates studies in other clinical settings. CONCLUSIONS: We discuss that this finding may be due to the conceptual differences between subjective and objective measures. Therefore, self-report and behavior-based measures should not be used as proxies of each other but as complementary measures that are useful for comprehensive diagnostics of cognitive impairments and assessment of risks for violent behavior.

Adverse events associated with anastomotic coupling devices in microvascular reconstruction.

OBJECTIVE: In light of the recent US Food and Drug Administration (FDA) Class 2 safety recall notice for anastomotic coupling devices, it is important to understand related adverse events. The aim of this study was to characterize adverse events in anastomotic coupling devices for microvascular reconstruction. METHODS: A retrospective cross-sectional analysis using the 2011 to 2021 US FDA Manufacturer and User Facility Device Experience (MAUDE) database. All reports of adverse events involving anastomotic coupling devices were retrieved from the MAUDE database. Descriptive statistics were used to analyze categorized events. RESULTS: There were a total of 293 documented adverse events related to anastomotic coupling devices. These adverse events resulted in 91 (31.1 %) patient injuries and 239 (81.6 %) device malfunctions. The most frequent patient problems were thrombosis/hematoma (n = 38; 41.8 %), unspecified injury (n = 31; 34.1 %), and failure to anastomose (n = 13; 14.3 %). Free flap necrosis was reported in 42 % of thrombosis/hematoma cases (n = 16). The most common malfunctions were devices operating differently than expected (n = 74; 31.0 %), connection problems (n = 41; 17.2 %), and twisted/bent material (n = 19; 7.9 %). There was no significant trend in the number of adverse events over the study period (p > 0.05). CONCLUSIONS: Adverse events from anastomotic coupling devices represent an important and modifiable factor in free tissue failure. Adverse events are predominately related to devices operating differently than expected and may result in vascular compromise of the free flap. Reconstructive surgeons should be cognizant of defective anastomotic coupling devices and be prepared to utilize traditional hand-sewn anastomosis.

Supraorbital Rim and Roof Reconstruction with Vascularized Fascia Lata and Autogenous Rib Graft.

OBJECTIVE: Describe a novel technique for reconstruction of complex defects involving supraorbital rim and orbital roof. METHODS: Retrospective chart review and description of surgical technique. RESULTS: Four patients underwent tumor resection with neurosurgery (2 intraosseous hemangioma, 1 meningioma, and 1 ossifying fibroma), with mean tumor size of 42.6 cubic centimeters on preoperative imaging. All defects involved supraorbital rim and orbital roof. Patients were reconstructed with autogenous osseous rib graft for structure and contour and anterolateral thigh fascia lata (ALTFL) free flap to provide robust vascularity to rib bone and as a barrier between skull base dura and the orbit and/or sinonasal cavities. Two patients underwent resection and reconstruction using minimal access incisions, and two underwent major cranial and skull base resections. All flaps are vascularized via superficial temporal vessels. On postoperative follow-up (mean 33.5 months, range 8-48), all patients report no vision change or diplopia, with excellent contour symmetry to contralateral orbit. Follow-up imaging (mean 29.5 months, range 3-48) demonstrated maintained orbital volume and retention of rib bone graft compared to immediate postoperative imaging. There were no complications related to graft use. Minor complications include 1 patient with cerebrospinal fluid leak managed with lumbar drain placement and 1 patient with mild enophthalmos at 7-month follow-up. CONCLUSION: We describe a series of patients who underwent a novel technique for reconstruction of complex defects involving supraorbital rim and orbital roof with autogenous osseous rib and vascularized ALTFL-free flap with excellent functional and cosmetic outcomes. This can be accomplished using minimal access techniques to minimize patient morbidity. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:654-658, 2024.

Minimally Invasive Approach to Access Vessels for Microvascular Anastomosis in Head and Neck Reconstruction.

OBJECTIVES: To describe our technique, review indications, and evaluate the outcomes of the minimal access approach for recipient vessel identification in microvascular tissue transfer. METHODS: Retrospective chart review of all patients who underwent microvascular reconstruction using the minimal access technique between 2015 and 2021. RESULTS: We report 236 cases, comprising 214 patients with a mean age of 60.2 years (3-88). The most common primary defect sites were the mandible (22.6%), cranium (14%), maxilla (13.2%), skull base (12.8%), and nose/nasal cavity (10.6%). Indications for free flap reconstruction included head and neck cancer extirpation (32.2%), osteoradionecrosis (29.7%), acquired deformity (14.0%), chronic wound (11.9%) and oral motor dysfunction (7.2%). Free flap donor sites used were the anterolateral thigh (84.3%), fibula (7.2%), and radial forearm (6.4%). Vessels utilized include superficial temporal (49.8%), facial (38.3%), angular (11.1%), and transverse cervical (0.4%). The overall complication rate was 14% (n = 33), with surgical complications at the recipient site accounting for 67.6% (n = 25). Flap failure occurred in 3.4% of procedures. Prior head and neck surgery and free flaps were associated with an increased risk of major recipient site complications (n = 20, p = 0.0257 and n = 14, p = 0.0117, respectively). CONCLUSION: Minimal access techniques allow consistent recipient vessel identification for microvascular-free tissue transfer. These approaches may be utilized in reconstructing a broad range of head and neck defects, are low morbidity, and contribute to an overall shorter length of stay.

Mandibular Osteoradionecrosis: Defining the Microbial Milieu and Antimicrobial Resistance at the Time of Rescue Flap Surgery.

OBJECTIVE: To report the microorganisms and their antibiotic sensitivity profile from tissue cultures and stains at the time of anterolateral thigh fascia lata (ALTFL) rescue flap for management of mandibular osteoradionecrosis (ORN). METHODS: Retrospective chart review of patients who underwent ALTFL rescue flap for native mandibular ORN between 2011 and 2022. RESULTS: Twenty-six cases comprising 24 patients (mean age 65.4 years, 65.4% male) with mandibular ORN from whom tissue cultures and gram stain were obtained at the time of ALTFL rescue flap. 57.7% grew bacterial species, while 34.6% grew fungal species. Multibacterial speciation was noted in 26.9% of cultures. A combination of bacterial and fungal growth was also seen in 15.4% of cases. All gram-positive cocci (GPC) were pansensitive to antibiotics except for one case of Staphylococcus aureus, which was resistant to levofloxacin. Gram-negative bacilli (GNB) species were isolated in 50.0% of cases. All fungal growth was due to Candida species. No growth was noted in 23.1% of cases. Multidrug resistance was noted in 53.8% of cases when GNB was isolated. CONCLUSION: We report 76.9% of our cases of mandibular ORN had microbial growth from tissue cultures obtained at the time of the ALTFL rescue flap. Fungal growth was noted in a substantial number of cases and should be obtained as a specimen when pursuing culture-driven antibiotic therapy. Most GPCs were pansensitive to antibiotics, while GNBs were often the harbinger of multidrug resistant mandibular ORN. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:166-169, 2024.

The curse of experiencing and committing violence as a criminal recidivism predictor: A comparison between female forensic psychiatric patients with severe mental disorders and substance use disorder.

BACKGROUND: Violence occurs frequently in the life of forensic psychiatric patients, both as active aggression and in the form of victimization. Undoubtedly, these incidents shape personality, behavior, and affect the ability to interact adequately socially. Thus, such experiences may influence criminal recidivism and serve as forensic psychiatric/psychological predictors upon hospital discharge. METHODS: Hence, this study aimed at characterizing two distinct female forensic psychiatric patient populations (nonsubstance use mental disorders [n = 110] versus substance use disorder [n = 415]) regarding their active and passive violent experiences as well as contextualizing these with their individual crime recidivism rates. The analysis followed a record-based, retrospective approach. RESULTS: While both groups experienced aggression throughout childhood and youth equally often, substance use disorder patients were significantly more often exposed to violence during adulthood. On the other hand, severely mentally ill patients tended to react more often with violence during their hospital confinement. However, regarding their violent recidivism rate, no intergroup effects were observed. Finally, within the addicted group, a violent index crime as well as physical aggression during hospital confinement increased the odds for violent reoffending by approximately 2.4-fold (95% confidence interval 1.3-4.5) and 2.5-fold (95% confidence interval 1.1-5.9), respectively. CONCLUSION: In summary, these findings underline the importance of active aggression rather than victimization as an influencing factor on resocialization especially in a substance use disorder patient population.

Variations in Payer-Negotiated Prices for Head and Neck Reconstructive Surgery.

OBJECTIVE: Little is known about pricing for reconstructive procedures of the head and neck. As of January 2021, the Centers for Medicare and Medicaid Services requires hospitals to disclose payer-negotiated prices for services, offering new insight into prices for privately insured patients. STUDY DESIGN: Cross-sectional analysis. SETTING: Turquoise database. METHODS: Payer-negotiated facility fees for 41 reconstructive surgeries were grouped by procedure type: primary closure, skin grafts, tissue rearrangement, locoregional flaps, or free flaps. Prices were normalized to account for local labor costs, then calculated as percent markup in excess of Medicare reimbursement. The mean percent markup between procedure groups was compared by the Kruskal-Wallis test. Subset analyses were performed to compare mean percent markup using a Student's t test. We also assessed price variation by calculating the ratio of 90th/10th percentile mean prices both across and within hospitals. RESULTS: In total, 1324 hospitals (85% urban, 81% nonprofit, 49% teaching) were included. Median payer-negotiated fees showed an increasing trend with more complex procedures, ranging from $379.54 (interquartile range [IQR], $230.87-$656.96) for Current Procedural Terminology (CPT) code 12001 ("simple repair of superficial wounds ≤2.5 cm") to $5422.60 ($3983.55-$8169.41) for CPT code 20969 ("free osteocutaneous flap with microvascular anastomosis"). Median percent markup was highest for primary closure procedures (576.17% [IQR, 326.28%-1089.34%]) and lowest for free flaps (99.56% [37.86%-194.02%]). Higher mean percent markups were observed for rural, for-profit, non-Northeast, nonteaching, and smaller hospitals. CONCLUSION: Wide variation in private payer-negotiated facility fees exists for head/neck reconstruction surgeries. Further research is necessary to better understand how pricing variation may correlate with out-of-pocket costs and quality of care.

Evaluation of Anterolateral Thigh Fascia Lata Rescue Flap for Mandibular Osteoradionecrosis.

Importance: Mandibular osteoradionecrosis (ORN) is a progressive disease that can be difficult to treat. Conservative measures often fail, while conventional definitive management requires a morbid segmental resection with osteocutaneous reconstruction. Evidence of the anterolateral thigh fascia lata (ALTFL) rescue flap technique's safety, effectiveness, and long-term outcomes is needed. Objective: To determine the long-term outcomes of the ALTFL rescue flap procedure for treating patients with mandibular ORN. Design, Settings, and Participants: This was a retrospective medical record review performed at a single tertiary-level academic health care institution with patients who were appropriate candidates for the ALTFL procedure to treat mandibular ORN from March 3, 2011, to December 31, 2022. Data analyses were performed from January 1 to March 26, 2023. Main Outcomes and Measures: Patient characteristics, preoperative radiographic Notani staging, intraoperative defect size, length of stay, complication rates, and clinical and radiographic findings of progression-free intervals. Results: The study population of 43 patients (mean [SD] age, 66.1 [47-80] years; 24 [55.8%] male individuals) included 52 cases of mandibular ORN. The preoperative Notani staging of the study population was known for 46 of the 52 total cases: 11 cases (23.9%) were stage I; 21 (45.7%), stage II; and 14 (30.4%), stage III. The mean defect area was 20.9 cm2. Successful arrest of ORN disease progression was noted in the clinical and radiographic findings of 50 of the 52 (96.2%) cases, with only 2 (3.8%) cases subsequently requiring fibular free flap reconstruction. The major complication rate was 1.9% (1 case). Clinical and radiographic progression-free intervals were assessed, and no statistically significant differences were noted between Notani staging groups (log-rank P = .43 and P = .43, respectively); ie, patients with stage III disease had no significant difference in risk of clinical (HR, 0.866; 95% CI, 0.054-13.853) or radiographic (HR, 0.959; 95% CI, 0.059-15.474) progression vs those with stage I disease. Weibull profiling revealed 96.9%, 94.6%, and 93.1% successful mandibular ORN arrest at 1, 3, and 5 years, respectively. The major complication rate was 1.9%. Mean (SD) length of stay was 2.7 (0.0-7.0) days. Mean (SD) radiographic follow-up was 29.3 (30.7) months. Conclusions and Relevance: The findings of this large retrospective patient case series support the continued success of the ALTFL rescue flap technique, a safe and highly effective long-term treatment for mandibular ORN in carefully selected patients.

Neurobiology of Aggression-Review of Recent Findings and Relationship with Alcohol and Trauma.

Aggression can be conceptualized as any behavior, physical or verbal, that involves attacking another person or animal with the intent of causing harm, pain or injury. Because of its high prevalence worldwide, aggression has remained a central clinical and public safety issue. Aggression can be caused by several risk factors, including biological and psychological, such as genetics and mental health disorders, and socioeconomic such as education, employment, financial status, and neighborhood. Research over the past few decades has also proposed a link between alcohol consumption and aggressive behaviors. Alcohol consumption can escalate aggressive behavior in humans, often leading to domestic violence or serious crimes. Converging lines of evidence have also shown that trauma and posttraumatic stress disorder (PTSD) could have a tremendous impact on behavior associated with both alcohol use problems and violence. However, although the link between trauma, alcohol, and aggression is well documented, the underlying neurobiological mechanisms and their impact on behavior have not been properly discussed. This article provides an overview of recent advances in understanding the translational neurobiological basis of aggression and its intricate links to alcoholism and trauma, focusing on behavior. It does so by shedding light from several perspectives, including in vivo imaging, genes, receptors, and neurotransmitters and their influence on human and animal behavior.

Management, Referral Patterns, and Outcomes in Bell's Palsy: A Single-Institution 903 Patient Series.

OBJECTIVE: In 2013, the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) published guidelines for Bell's palsy (BP), including recommendations for workup, management, and specialist referral. Patients with BP often present to primary care; however, adherence to guidelines may vary by setting. This study sought to evaluate the management of patients with BP presenting to primary care, emergency department (ED), and urgent care settings. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary care center. METHODS: Retrospective chart review of patients identified by diagnosis code for BP. RESULTS: A total of 903 patients were included; 687 (76.1%) presented to ED, 87 (9.6%) to internal medicine, 77 (8.5%) to family medicine, and 52 (5.8%) to urgent care. On presentation, 804 (89.0%) patients were prescribed corticosteroids and 592 (65.6%) antiviral therapy. Steroid therapy ranged from 1 dose to greater than a 14-day course, with 177 (19.6%) receiving an adequate duration of 10 days or greater. Referrals were provided to facial plastics and/or otolaryngology for 51 patients (5.6%). For all comers, 283 (31.3%) had complete resolution, 197 (21.8%) had an incomplete resolution, 62 (6.9%) had persistent palsy, and 361 (40.0%) lost to follow-up. In assessing the association between clinic setting and management, appropriate corticosteroid therapy (p < .01), imaging (p < .01), and eye care (p < .01) were statistically significant. CONCLUSION: Adherence to guidelines for BP management varies amongst providers. In our study cohort, 15.5% of patients received medical therapy in accordance with AAO-HNS guidelines, and only 5.6% were referred to facial plastics. To facilitate more appropriate care, tertiary care institutions may benefit from system-wide care pathways to manage acute BP.

Rates of osteoradionecrosis in resected oral cavity cancer reconstructed with free tissue transfer in the intensity-modulated radiotherapy era.

BACKGROUND: Resected oral cavity carcinoma defects are often reconstructed with osteocutaneous or soft-tissue free flaps, but risk of osteoradionecrosis (ORN) is unknown. METHODS: This retrospective study included oral cavity carcinoma treated with free-tissue reconstruction and postoperative IMRT between 2000 and 2019. Risk-regression assessed risk factors for grade ≥2 ORN. RESULTS: One hundred fifty-five patients (51% male, 28% current smokers, mean age 62 ± 11 years) were included. Median follow-up was 32.6 months (range, 1.0-190.6). Thirty-eight (25%) patients had fibular free flap for mandibular reconstruction, whereas 117 (76%) had soft-tissue reconstruction. Grade ≥2 ORN occurred in 14 (9.0%) patients, at a median 9.8 months (range, 2.4-61.5) after IMRT. Post-radiation teeth extraction was significantly associated with ORN. One-year and 10-year ORN rates were 5.2% and 10%, respectively. CONCLUSIONS: ORN risk was comparable between osteocutaneous and soft-tissue reconstruction for resected oral cavity carcinoma. Osteocutaneous flaps can be safely performed with no excess concern for mandibular ORN.

Free Tissue Transfer for Skull Base Osteoradionecrosis: A Novel Approach in the Endoscopic Era.

OBJECTIVES: Osteoradionecrosis (ORN) of the skull base and craniovertebral junction is a challenging complication of radiation therapy (RT). Severe cases often require surgical intervention through a multi-modal approach. With the evolution in endoscopic surgery and advances in skull base reconstruction, there is an increasing role for microvascular free tissue transfer (MFTT). We describe an endoscopic-assisted approach for the management of ORN of the skull base using fascia lata for MFTT. STUDY DESIGN: Retrospective case series. METHODS: Between 2017 and 2021, a review of all cases in which fascia lata MFTT was utilized for skull base ORN was performed. Patient demographics, preoperative characteristics, and postoperative outcomes with long-term follow-up were reviewed. RESULTS: Five patients were identified. Mean duration to onset of ORN was 17 months following RT. A trial of antibiotics, hyperbaric oxygen (HBO), and/or limited debridement was attempted without success. Refractory pain and progressive osteomyelitis were unifying symptoms. All patients underwent endoscopic debridement of the affected region of ORN prior to MFTT. Vascularized fascia lata was inset through a combined endonasal and transoral corridor. There was improvement in chronic pain in the postop setting with no patients requiring continued antibiotics or HBO therapy. Mean post-op follow-up was 23 months. CONCLUSIONS: With continued evolution in endoscopic, minimally invasive approaches, there is an expanding indication for early surgical management in refractory ORN. Fascia lata MFTT is a novel and effective strategy for the management of ORN of the skull base and upper cervical spine with excellent postoperative outcomes and limited patient morbidity.

Relevance of neurocognition in chronic pain syndrome: a systematic and methodical approach.

INTRODUCTION: Subjective and objective deficits in neurocognitive domains are well-documented in patients with chronic pain. However, neurocognitive deficits have not been investigated consistently. The main objective of this study was to conduct a comprehensive assessment of self-rated and objectively assessed cognitive differences between patients with chronic pain (CP) and healthy controls (HC). METHOD: The cognitive functioning of 40 CP and 41 HC was assessed using a standardized computer-based test battery, enabling a comparison of subjective and objective neurocognitive factors. To achieve this, the Vienna Test System (VTS) was utilized, incorporating standardized tests from the Cognitive Basic Assessment Battery (COGBAT) with the advantage of objectivity, reliability, validity, efficiency, utility, and standardization. This approach enables the evaluation of cognitive functioning across all pertinent domains. RESULTS: CP reported cognitive deficits in overall performance as well as specific functions, such as attention, memory, and executive functions. Across all neurocognitive domains, CP showed a poorer performance. Affected subdomains of attention were intensity and selectivity of attention. Lower performance was found also in concentration performance, obtaining and overview, visual orientation performance and reactive stress tolerance. Regarding memory, CP performed worse in figural episodic memory and recognition tasks. In addition, CP exhibited poorer performance in mental flexibility, working memory, planning ability, and inhibition as components of executive functioning, when compared to HC. CONCLUSIONS: CP expressed subjective cognitive deficits and demonstrated impaired neurocognitive performance.
