RESUMEN
Background: Treatment of Bell's palsy ranges from medical management with high-dose corticosteroids to complex facial reanimation procedures. Objective: To characterize the number of static, dynamic, and combined facial reanimation procedures for the management of Bell's palsy using a national database over time. Methods: This retrospective cohort study included patients in the 2013-2020 National Surgical Quality Improvement Project database with a postoperative diagnosis of Bell's palsy. Cases were categorized as involving only static, only dynamic, and a combination of static and dynamic procedures. Chi-square or Fisher's exact tests were performed for patient demographics, and linear regressions were created to evaluate utilization trends. Results: In total, 294 patients were identified. There was no significant difference in patient sex and comorbidities between these treatment groups. Of the 294 patients, 101 received both types of procedures, 107 received only dynamic procedures, and 86 received only static procedures. The trendlines for all treatment groups were significantly positive (B = 1.27 for both, B = 0.89 for dynamic only, and B = 1.01 for static only). Conclusion: In this study of a national surgical database, an increase in static, dynamic, and combined treatments for patients with Bell's palsy was found.
RESUMEN
OBJECTIVE: To assess the long-term outcomes and efficacy of respiratory retraining therapy in patients with exercise-induced laryngeal obstruction (EILO). METHODS: A retrospective chart review and prospective questionnaire-based survey were conducted on 88 patients who received respiratory retraining therapy for EILO at our institution over the past 5 years RESULTS: Thirty-four patients were included in the final analysis, with a mean age at symptom onset and age at initial evaluation of 13.67 ± 2.96 and 15.12 ± 3.48, respectively. We found a statistically significant difference in the pretreatment and post-treatment Dyspnea indices following respiratory retraining therapy, with a mean difference of 12.03 ± 7.18 (P < 0.001). When asked about the effectiveness of respiratory retraining therapy, the majority of patients (n = 28) reported improvement (13.3% "a little," 13.3% "somewhat better," 53.3% ("a lot better," and 13.3% complete resolution of symptoms. Only two patients (6.7%) responded that their breathing "did not get better." The most effective therapy techniques cited by patients were abdominal breathing (n = 10), ratio breathing (n = 5), and pursed lips or "straw" breathing (n = 5). CONCLUSIONS: Respiratory retraining therapy represents an effective technique in both the short-term and long-term management of EILO. This therapy remains the first line in the management of EILO due to its ease of administration, non-invasive nature, and durable effect on breathing function.
RESUMEN
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.
RESUMEN
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. LEVEL OF EVIDENCE: 2 Laryngoscope, 134:2177-2181, 2024.

BACKGROUND: While the etiology of Bell's palsy (BP) is largely unknown, current evidence shows it may occur secondary to the immune response following a viral infection. Recently, BP has been reported as a clinical manifestation of coronavirus disease (COVID-19). OBJECTIVES: To investigate an association between COVID-19 infection and BP. Additionally, to evaluate the need for COVID-19 testing in patients who present with BP. METHODS: Hospital records of patients who presented to a single tertiary care center with BP in 2020 and 2021 were reviewed for presenting symptoms, demographics, COVID-19 infection and vaccination status. RESULTS: There was no statistically significant difference between patients with BP who had a positive or negative COVID test in terms of sex, BMI, age, race, smoking history or alcohol use. All 7 patients with BP and a positive COVID test were unvaccinated. Of the total cohort of 94 patients, 82 % were unvaccinated at the time of the study. None of the 17 patients who were vaccinated had a positive COVID test. A history of BP showed no statistical significance (10.3 % vs 14.3 %, p-value 0.73). CONCLUSION: We discovered a limited cohort of patients who underwent COVID-19 testing at the time of presentation for BP. Though there have been recent studies suggesting a COVID-19 and BP, we were unable to clearly identify a relationship between COVID-19 and BP. Interestingly, all patients with facial paralysis and COVID-19 were unvaccinated. To further study this relationship, we recommend consideration of a COVID-19 test for any patient that presents with facial paralysis.

OBJECTIVE: To assess emergency department (ED) abdominopelvic computed tomography (CT) imaging utilization and findings in patients with known human immunodeficiency virus (HIV) positive status. MATERIALS AND METHODS: A retrospective chart review of imaging, clinical, and laboratory data was performed for HIV positive patients who demonstrated HIV-related findings on abdominopelvic CT imaging performed within the ED. RESULTS: One hundred and eighty-eight patients with 522 CT scans of the abdomen and/or pelvis were reviewed. 47 patients with HIV presenting to the ED on 82 separate occasions were included in this study (mean age 43.3 years). Patients presented to the ED with infectious/inflammatory disease (n = 54) or history of HIV-related malignancy or new/worsening HIV-related malignancy (n = 28). The most common findings on abdominopelvic CT were anorectal pathology including anorectal abscess or proctitis (n = 22), followed by colitis (n = 19). Findings of HIV-associated malignancy were less common, including anal/rectal cancer (n = 7), Kaposi's sarcoma (n = 4), and lymphoma (n = 2). At the time of ED visit, 25.6% (n = 21) of patients had acquired immunodeficiency syndrome (AIDS). Higher WBC counts were found in the infectious/inflammatory group (P = 0.021) and patients without AIDS (P = 0.0159), while lower WBC counts were associated with new or worsening malignancy (P = 0.007) and AIDS (P = 0.0000). Patients with AIDS were more likely to be deceased at the time of our study. CONCLUSIONS: The majority of ED visits within our population were attributed to infectious/inflammatory etiologies. CT findings demonstrated predominantly infectious/inflammatory processes, with anorectal pathology being the most common. Findings of malignancy on CT were less common, while opportunistic infections and AIDS-defining malignancies were uncommon.

PURPOSE: The aim of this study was to analyze chest CT imaging findings and relevant clinical factors in patients with HIV presenting to the emergency department (ED). MATERIALS AND METHODS: A retrospective review was performed to identify patients with HIV who received chest CT imaging evaluation in the acute ED setting. Analyzed patients included adults with a known diagnosis of HIV who presented to the ED at a single tertiary care center between 2004 and 2020 and received chest CT imaging. Chest CT findings were assessed by 2 radiologist readers, and relevant clinical data were gathered. Statistical analysis was performed to determine if imaging and clinical factors demonstrate significant associations with CD4 count, viral load, and antiretroviral therapy status. RESULTS: A total of 113 patients with HIV were identified who presented to the ED and underwent chest CT imaging evaluation (mean age 47 ± 11 years). Frequently detected chest CT findings included infectious pneumonia (24%), malignancy (11%), pleural effusion (17%), pericardial effusion (13%), and pulmonary embolism (4%). CD4 count, viral load, and active retroviral therapy demonstrated statistically significant associations with a number of key imaging and clinical factors, including presence of pneumonia, malignancy, average length of hospital admission, and survival. CONCLUSION: Patients with HIV present with a wide range of imaging findings when presenting in the acute ED setting. CD4 count, viral load, and active retroviral therapy status demonstrate statistically significant associations with multiple key imaging findings and clinical factors. Chest CT plays an integral role in the clinical management of this unique patient population.

ABSTRACT: Treatment strategies for malignant melanoma have rapidly evolved over the past decade. Because of its propensity to develop advanced stage and metastatic disease, melanoma has contributed to the majority of mortalities among patients with skin cancer. The development of novel therapeutics such as immunotherapy and targeted molecular therapies has revolutionized the treatment of patients with advanced stage and metastatic malignant melanoma. Immune checkpoint inhibitors, BRAF/MEK inhibitors, and other revolutionary therapies have demonstrated remarkable success in the treatment of this common malignancy. Along with these advancements in systemic therapies, imaging has continued to play a critical role in the diagnosis and follow-up of patients with malignant melanoma. As the use of these novel therapies continues to expand, knowledge of the evolving therapeutic landscape of melanoma is becoming critical for radiologists. In this review, we provide a primer for radiologists outlining the evolution of immunotherapy and targeted therapy in the treatment of melanoma. We discuss the critical role of imaging in evaluation of treatment response, including a summary of current imaging response guidelines. Last, we summarize the essential role of imaging in the evaluation of potential adverse events seen in patients with malignant melanoma undergoing treatment with immune checkpoint inhibitors.

Patients with human immunodeficiency virus (HIV) can present with a wide range of different acute and chronic pathologies. Anorectal conditions are particularly common in this unique patient population, including pathologies, such as proctitis, anorectal abscess, anorectal fistula, and anal squamous cell carcinoma. The radiologist plays a critical role in the assessment of these common forms of anorectal disease, as these conditions can present with various findings on imaging assessment. Pelvic CT, MRI, and FDG-PET/CT are among the most common modalities used for assessment of anorectal disease in the HIV patient population. Knowledge of the fundamental clinical and imaging findings associated with these pathologies in HIV patients is critical for radiologists.

Primary peritoneal serous carcinoma (PPSC) is a rare primary peritoneal tumor characterized by a unique range of clinical features and imaging findings. Though it shares many clinical, histologic, and imaging features with serous ovarian carcinoma, it remains a distinct clinical entity. Although less common than its primary ovarian counterpart, PPSC is characterized by a prognosis that is often equally poor with presentations common in late stages of disease. Key imaging modalities used in the evaluation of PPSC include ultrasound, CT, MRI, and PET/CT. For radiologists, an understanding of the pertinent imaging findings, pathologic correlations, and clinical features of PPSC is essential for arriving at the correct diagnosis and guiding the subsequent appropriate management of this complex malignancy.

PURPOSE: To analyze emergency department (ED) computerized tomography (CT) utilization in cancer patients with coronavirus disease 2019 (COVID-19). METHODS: A retrospective chart review was performed to identify cancer patients who received COVID-19 diagnosis within the single healthcare system and presented to the ED within 30 days of COVID-19 positive date between May 1 and December 31, 2020. RESULTS: In our 61 patients, the mean age was 72.5 years old, with 34% of patients (n = 21) on active cancer therapy and 66% (n = 40) on surveillance only. Most patients (n = 53) received their COVID-19 diagnosis within the ED, with 8 patients diagnosed prior to initial ED visit. The most common CT studies ordered within the ED were CT chest (n = 25), CT abdomen/pelvis (A/P) (n = 20), CT head (n = 8), and CT chest/abdomen/pelvis (C/A/P) (n = 7). COVID-19 findings were present on 33 scans, findings of worsening malignancy on 12 scans, and non-COVID non-cancer findings on 9 scans. Significant differences in CT severity score (p = 0.0001), indication for hospitalization (p = 0.026), length of hospitalization (p = 0.004), interventions (remdesivir, mechanical ventilation, and vasopressor support) while hospitalized (p < 0.05), and mortality (p = 0.042) were found between the prior diagnosis and ED diagnosis groups. No such differences were found between the active treatment and surveillance groups. CONCLUSION: ED CT imaging findings in patients with cancer and COVID-19 are predominantly related to COVID-19 infection, rather than cancer history or anti-cancer therapy status.

ABSTRACT: Lung cancer continues to be a major cause of death throughout the world. The ability to both accurately diagnose lung cancer in its early stages and monitor response to treatment is essential to reducing the morbidity and mortality associated with the disease. Serum tumor markers have been identified as potential biomarkers that may aid in lung cancer diagnosis and surveillance. These markers, when combined with cross-sectional imaging, may result in more robust screening and surveillance protocols. The future role of serum tumor markers in lung cancer includes the advancement of "liquid biopsies," in which peripheral blood samples are analyzed for tumor components without the need for a tissue biopsy.

Hypercalcemia is a marker for a wide variety of underlying etiologies, and its presentation in the emergency setting may be asymptomatic, incidental, or a primary complaint with associated symptoms and physical exam findings. While the workup is initially driven through serum laboratory testing, imaging plays an important role in diagnosis and post-treatment follow up. This review covers multiple common and uncommon etiologies of hypercalcemia, details their underlying mechanisms, and identifies the most important associated imaging findings. It is important for radiologists to be familiar with these etiologies and imaging findings, particularly in the emergency setting since hypercalcemia may represent the only significant laboratory abnormality associated with the presenting condition. Furthermore, the radiologist's interpretation of a study may be directly influenced by knowing about a patient's hypercalcemia.

OBJECTIVE: The study aims to demonstrate risk factors for colitis in intensive care unit patients with and without coronavirus disease 2019 (COVID-19). METHODS: Retrospective review was performed to identify intensive care unit (ICU) patients with the diagnosis of COVID-19 with computed tomography (CT) between March 20 and December 31, 2020. ICU patients without COVID-19 diagnosis with CT between March 20 and May 10, 2020 were also identified. CT image findings of colitis or terminal ileitis as well as supportive treatment including ventilator, vasopressors, or extracorporeal membrane oxygenation (ECMO) were recorded. Statistical analysis was performed to determine if clinical factors differed in patients with and without positive CT finding. RESULTS: Total 61 ICU patients were selected, including 32 (52%) COVID-19-positive patients and 29 (48%) non-COVID-19 patients. CT findings of colitis or terminal ileitis were identified in 27 patients (44%). Seventy-four percent of the patients with positive CT findings (20/27) received supportive therapies prior to CT, while 56% of the patients without abnormal CT findings (19/34) received supportive therapies. Vasopressor treatment was significantly associated with development of colitis and/or terminal ileitis (p = 0.04) and COVID-19 status was not significantly different between these groups (p = 0.07). CONCLUSIONS: In our study, there was significant correlation between prior vasopressor therapy and imaging findings of colitis or terminal ileitis in ICU patients, independent of COVID-19 status. Our observation raises a possibility that the reported COVID-19-related severe gastrointestinal complications and potential poor outcome could have been confounded by underlying severe critically ill status, and warrants a caution in diagnosis of gastrointestinal complication.
