RESUMEN

Maackia amurensis lectins serve as research and botanical agents that bind to sialic residues on proteins. For example, M. amurensis seed lectin (MASL) targets the sialic acid modified podoplanin (PDPN) receptor to suppress arthritic chondrocyte inflammation, and inhibit tumor cell growth and motility. However, M. amurensis lectin nomenclature and composition are not clearly defined. Here, we sought to definitively characterize MASL and its effects on tumor cell behavior. We utilized SDS-PAGE and LC-MS/MS to find that M. amurensis lectins can be divided into two groups. MASL is a member of one group which is composed of subunits that form dimers, evidently mediated by a cysteine residue in the carboxy region of the protein. In contrast to MASL, members of the other group do not dimerize under nonreducing conditions. These data also indicate that MASL is composed of 4 isoforms with an identical amino acid sequence, but unique glycosylation sites. We also produced a novel recombinant soluble human PDPN receptor (shPDPN) with 17 threonine residues glycosylated with sialic acid moieties with potential to act as a ligand trap that inhibits OSCC cell growth and motility. In addition, we report here that MASL targets PDPN with very strong binding kinetics in the nanomolar range. Moreover, we confirm that MASL can inhibit the growth and motility of human oral squamous cell carcinoma (OSCC) cells that express the PDPN receptor. Taken together, these data characterize M. amurensis lectins into two major groups based on their intrinsic properties, clarify the composition of MASL and its subunit isoform sequence and glycosylation sites, define sialic acid modifications on the PDPN receptor and its ability to act as a ligand trap, quantitate MASL binding to PDPN with KD in the nanomolar range, and verify the ability of MASL to serve as a potential anticancer agent.

RESUMEN

Plasmacytoid dendritic cells (pDCs) have been implicated as having a role in antifungal immunity, but mechanisms of their interaction with fungi and the resulting cellular responses are not well understood. In this study, we identify the direct and indirect biological response of human pDCs to the fungal pathogen Aspergillus fumigatus and characterize the expression and regulation of antifungal receptors on the pDC surface. Results indicate pDCs do not phagocytose Aspergillus conidia, but instead bind hyphal surfaces and undergo activation and maturation via the upregulation of costimulatory and maturation markers. Measuring the expression of C-type lectin receptors dectin-1, dectin-2, dectin-3, and mannose receptor on human pDCs revealed intermediate expression of each receptor compared with monocytes. The specific dectin-1 agonist curdlan induced pDC activation and maturation in a cell-intrinsic and cell-extrinsic manner. The indirect activation of pDCs by curdlan was much stronger than direct stimulation and was mediated through cytokine production by other PBMCs. Overall, our data indicate pDCs express various C-type lectin receptors, recognize and respond to Aspergillus hyphal Ag, and serve as immune enhancers or modulators in the overarching fungal immune response.

RESUMEN

OBJECTIVES: Tympanostomy tubes can prevent sequelae of otitis media that adversely affect long term hearing and language development in children. These negative outcomes compound the existing difficulties faced by children who are already diagnosed with developmental disorders. This study aims to characterize this subset of children with developmental disorders undergoing myringotomy and tympanostomy tube insertion. METHODS: A retrospective review using the Kids' Inpatient Database (KID) was conducted, with codes from International Classification of Diseases, Ninth Revision used to query data from the years 2003 to 2012 to determine a study group of children with a diagnosis of a developmental disorder undergoing myringotomy and tympanostomy insertion. This group was compared statistically to patients undergoing these procedures who did not have a diagnosed developmental disorder. RESULTS: In total, 21 945 cases of patients with myringotomy with or without tympanostomy tube insertion were identified, of which 1200 (5.5%) had a diagnosis of a developmental disorder. Children with developmental disorders had a higher mean age (3.3 years vs 2.9 years, P = .002) and higher mean hospital charges ($43 704.77 vs $32 764.22, P = .003). This cohort also had higher proportions of black (17.6% vs 12.3%, P < .001) and Hispanic (23.9% vs 20.6%, P = .014) patients, and had lower rates of private insurance coverage (39.6% vs 49%, P < .001). CONCLUSION: The population of children with developmental disorders undergoing myringotomy or tympanostomy tube placement has a different demographic composition than the general population and faces distinct financial and insurance coverage burdens. Further study should be done to assess if these differences impact long term outcomes.

RESUMEN

OBJECTIVES: Tonsillectomy is one of the most common otolaryngologic procedures. Hemorrhage after tonsillectomy is one of the most feared complications by surgeons and patients alike. The objective of this study was to analyze the risk factors associated with an increase in post-tonsillectomy hemorrhage in the pediatric population using a large national database. METHODS: The Kids' Inpatient Database (KID) from 2000 to 2012 was queried for patients between the ages of 1 to 17 years with post-tonsillectomy hemorrhage. Univariate and multivariate analyses were performed to obtain trends in patient demographics, comorbidities, and hospital information. RESULTS: Overall 45 940 pediatric cases of tonsillectomy were identified of which 5470 (11.9%) resulted in postoperative hemorrhage. Patients with postoperative hemorrhage were significantly older with mean age of 8.62 (±4.75) compared to all patients. Females were found to have higher rates of hemorrhage when compared to males 14.6% versus 11.5% (P < .001). The rate of white patients who had hemorrhage was 16.3% (P < .001). The most common comorbidities significantly associated with hemorrhage were fluid and electrolyte disorders (6.6% P < .001), deficiency anemia (3.8%; P < .001), and coagulopathy (2.7%; P < .001). Urban nonteaching hospitals had higher rates of hemorrhage (19.6%; P < .001) and the Northeast was the most common region (15.2%; P < .001). On multivariate analysis, older patients and white ethnicity showed a significantly increased risk of hemorrhage. Patients with pre-existing comorbidities such as coagulopathy, deficiency anemia, and fluid and electrolyte disorders circulation were also found to have higher odds ratios of bleeding. CONCLUSION: Postoperative hemorrhage is a common complication following tonsillectomy with a rate of 11.9% in this study. A higher rate of hemorrhage was seen with increasing age, white race, and males overall, as well as patients with fluid and electrolyte disorders. Urban non-teaching hospitals and the Northeast region also saw increased rates of hemorrhage.

RESUMEN

BACKGROUND: Self-management regimens for oral and oropharyngeal cancer survivors can be complex and challenging. Effective self-management skills can foster better outcomes. We report on the development, feasibility, and pilot testing of a web-based self-management tool called "Empowered Survivor" (ES) for survivors of oral and oropharyngeal cancer. METHODS: ES content was developed in two phases, with modules focusing on oral care, swallowing and muscle strength, and long-term follow-up. This single-arm pilot study consisted of a pre-, 2-month, and a 6-month postintervention survey. RESULTS: Enrollment rates were relatively low. Once enrolled, data collected from the ES website indicated that 81.8% viewed ES. Participants provided positive evaluations of ES. Preliminary results indicate that ES had a beneficial impact on self-management self-efficacy, preparedness for survivorship care, and quality of life. ES improved survivors' engagement in oral self-exams and head and neck strengthening exercises, improved ability to address barriers, and decreased information and support needs. CONCLUSIONS: This study provides preliminary evidence of engagement, acceptability, and beneficial impact of ES, which should be evaluated in a larger controlled clinical trial.

RESUMEN

Otolaryngology is a competitive specialty, with 398 US seniors applying to an offered 328 positions in 2019. Recent changes to US Medical Licensing Exam (USMLE) Step 1 scoring raise many questions for both medical student applicants and program directors. Otolaryngologists are known to be collegial and thoughtful physicians. Focusing on other nonstandardized testing scores may help the specialty "reboot" and refocus on recruiting the best people, not just applicants with a high Step 1 score and Alpha Omega Alpha (AOA) status.

RESUMEN

Plasmacytoid dendritic cells (pDCs) are potent producers of type I and type III IFNs and play a major role in antiviral immunity and autoimmune disorders. The innate sensing of nucleic acids remains the major initiating factor for IFN production by pDCs. TLR-mediated sensing of nucleic acids via endosomal pathways has been studied and documented in detail, whereas the sensing of DNA in cytosolic compartment in human pDCs remains relatively unexplored. We now demonstrate the existence and functionality of the components of cytosolic DNA-sensing pathway comprising cyclic GMP-AMP (cGAMP) synthase (cGAS) and stimulator of IFN gene (STING) in human pDCs. cGAS was initially located in the cytosolic compartment of pDCs and time-dependently colocalized with non-CpG double-stranded immunostimulatory DNA (ISD). Following the colocalization of ISD with cGAS, the downstream pathway was triggered as STING disassociated from its location at the endoplasmic reticulum. Upon direct stimulation of pDCs by STING agonist 2'3' cGAMP or dsDNA, pDC-s produced type I, and type III IFN. Moreover, we documented that cGAS-STING-mediated IFN production is mediated by nuclear translocation of IRF3 whereas TLR9-mediated activation occurs through IRF7. Our data also indicate that pDC prestimulation of cGAS-STING dampened the TLR9-mediated IFN production. Furthermore, triggering of cGAS-STING induced expression of SOCS1 and SOCS3 in pDCs, indicating a possible autoinhibitory loop that impedes IFN production by pDCs. Thus, our study indicates that the cGAS-STING pathway exists in parallel to the TLR9-mediated DNA recognition in human pDCs with cross-talk between these two pathways.

RESUMEN

OBJECTIVES/HYPOTHESIS: To evaluate the "July effect," as a possible risk factor for perioperative complications in otolaryngology microvascular reconstruction during the transitional period in the academic calendar. STUDY DESIGN: Retrospective database review. METHODS: Microvascular reconstruction outcomes in the National Surgical Quality Improvement Program (2005-2016) database were compared between the first academic quarter (July-September) to the last academic quarter (April-June). The primary outcome was 30-day morbidity, and secondary outcomes included 30-day mortality, operative complications, or postoperative adverse events. RESULTS: There were 612 and 580 patients who underwent microvascular reconstruction during the first and last academic quarters, respectively. There was no significant difference between the 30-day mortality between the first academic quarter (1.5%) and the last academic quarter (0.7%) (P = .194). There was no difference in 30-day morbidity (47.9% vs. 49.5%, P = .586), operative complications (wound disruption, P = .151; bleeding, P = .526; operative time, P = .162), or postoperative adverse events (deep vein thrombosis, P = .460; pneumonia, P = .737; reintubation, P = .201; pulmonary embolism, P = .452; ventilation for >48 hours, P = .769; acute renal failure, P = .500; urinary tract infection, P = .693; unplanned readmission, P = .202; and mean length of stay, P = .497). CONCLUSIONS: There appears to be no July effect in microvascular reconstruction. Further studies should identify the mechanisms that preserve the safety of this operation year-round for application to other areas of medicine who have observed the July effect.

RESUMEN

OBJECTIVES: To identify risk factors of perioperative blood transfusions (PBTs) for neck dissection and identify the association of PBTs with other postoperative outcomes. METHODS: This is a retrospective study of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. The database was queried for neck dissection procedures performed by otolaryngologists from 2006 to 2014. Multivariable logistic regression was used to determine associations between demographic and preoperative factors, mortality, unplanned reoperation, and unplanned readmission with PBTs. RESULTS: Of the 3090 patients included in our study, 346 (11.2%) received a PBT, 249 patients (72.0%) received blood intraoperatively or on postoperative day (POD) 0, and 97 patients (28.0%) received blood within 5 PODs. American Society of Anesthesiologists (ASA) class ≥3 (odds ratio [OR], 2.1; 95% confidence interval [CI], 1.4-3.2), preoperative weight loss (OR, 2.2; 95% CI, 1.5-3.2), and anemia (OR, 5.5; 95% CI, 4.1-7.6) were independently associated with PBTs. Free flaps were also significantly associated with PBTs. PBTs were significantly associated with unplanned return to the operating room within 30 days (OR, 4.31; 95% CI, 3.01-6.18) but not with 30-day unplanned readmission or 30-day mortality. DISCUSSION: Eleven percent of patients undergoing neck dissection receive a PBT. Identifying associated risk factors may reduce PBT among patients with cancer. Comorbid data, such as weight loss, anemia, and ASA class, may be useful in determining risk for transfusion during these procedures. IMPLICATIONS FOR PRACTICE: Awareness of preoperative risk factors for PBT may lead surgeons to reduce the risk of PBT, anticipate the need for transfusion, and manage these patients carefully to prevent unplanned reoperation.

RESUMEN

OBJECTIVES: As the country ages, thyroidectomies can be expected to be performed more frequently among the elderly. In this study, we stratified patients by age to explore demographics and complications of patients undergoing thyroidectomy. STUDY DESIGN: Retrospective study with a national database. SETTING: Nationwide Inpatient Sample. SUBJECTS AND METHODS: A total of 414,079 thyroidectomy cases from 2005 to 2013 were identified. Complications, outcomes, demographics, length of stay, and hospital charges were evaluated among patients and stratified by age into 4 cohorts: younger (<65 years), advanced age (65-74 years), elderly (75-84 years), and superelderly (≥85 years). RESULTS: Of 414,079 thyroidectomy cases identified, patients aged <65 years accounted for 75.6% of cases, while those aged 65-74, 75-84, and ≥85 years accounted for 16.3%, 7.2%, and 0.9%, respectively ( P < .001). There was a significant difference in length of stay, total hospital charges, and mortality throughout the different age groups ( P < .001), all trending upward with advancing age. In the aging population, incidence of recurrent laryngeal nerve injury, transfusion of erythrocytes, and acute cardiac complications increased with increasing age ( P < .001), while hypoparathyroidism decreased with age ≥65 but ≤85 years ( P < .001). Patients aged ≥75 years had increased odds of mortality as compared with their younger counterparts ( P < .001). CONCLUSION: This study utilized a national database to describe and elucidate trends in older populations undergoing thyroidectomy. Thyroid-related complications, including blood transfusion and recurrent laryngeal nerve injury, increased with increasing patient age. This information will help to guide pre- and postoperative care for aging patients undergoing thyroidectomy.

RESUMEN

OBJECTIVES/HYPOTHESIS: Many human immunodeficiency virus (HIV)-infected pediatric patients develop otolaryngologic disease. We aimed to characterize their otolaryngologic manifestations by type and demographic variation, and model temporal trends. STUDY DESIGN: Retrospective cohort review. METHODS: A retrospective review utilizing the Kids' Inpatient Database (KID) was conducted. International Classification of Diseases, Ninth Revision, Clinical Modification codes for HIV and otolaryngologic diagnoses were used to query data from the triennially published KID files from 1997 to 2012. A subset analysis of infectious versus non-infectious admitting otolaryngologic diagnoses was conducted. RESULTS: A total of 11,150 cases met the inclusion criteria. Of these cases, 21.8% were admitted for otolaryngologic manifestations, with 18.0% presenting with infectious symptomatology, 4.8% with noninfectious disease, and 1.0% with both. On average, patients presenting with infectious disease were younger (8.17 years vs. 9.65 years, P < .001). Patients in the South were significantly more likely to be admitted for infection (54.8% vs. 42.0%, P < .001), with non-infectious predominance in the Northeast and West. HIV-infected children in 1997 were more likely to present with infectious otolaryngologic disease (56.3% vs. 45.8%, P < .001); however, there has been a decrease in the prevalence of infectious head and neck presentations (46.5%, 19.9%, 11.5%, 6.7%, 3.7%, and 1.9% from 1997 to 2012), and a gradual shift toward noninfectious manifestation with notable differences in 2000 and 2012 (19.9% vs. 25.2%; P = .017; and 1.9% vs. 4.8%, P < .001, respectively). CONCLUSIONS: Otolaryngologic disease accounts for nearly one-fifth of hospitalizations in HIV-infected children; however, rates of hospitalization as well as otolaryngologic manifestations have progressively decreased over time. HIV-infected children nowadays are more likely to present with noninfectious rather than infectious disease. LEVEL OF EVIDENCE: NA Laryngoscope, 129:E377-E382, 2019.

RESUMEN

BACKGROUND: Increased anesthesia time may lead to respiratory complications in patients receiving tracheostomy, which contributes to patient morbidity. METHODS: The American College of Surgeon's National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for cases of planned tracheostomy (CPT 31600) from 2005 to 2012. Patients were stratified into quintiles based on anesthesia duration. Pearson's chi square, Fischer's exact test, one-way ANOVA, and multivariate regression were used to determine the association between patient characteristics with pneumonia and ventilator dependence. RESULTS: Out of 752 patients, 83 patients experienced post-operative pneumonia, and 166 experienced ventilator dependence. Following multivariate regression analysis, anesthesia quintiles were not significantly associated with pneumonia or ventilator dependence. Age (OR 1.03, 95% CI 1.00-1.05, P = .032), dyspnea (OR 2.21, 95% CI 1.18-4.13; P = .013), pre-operative ventilator dependence (OR 3.08, 95% CI 1.19-7.98; P = .020), and sepsis (OR 6.68, 95% CI 3.19-14.0; P < .001) remained as significant predictors of post-operative ventilator dependence. CONCLUSIONS: Faster may not be better-- prolonged anesthesia time does not increase the risk of post-operative pneumonia or ventilator dependence in patients receiving a planned tracheostomy in the operating room.

RESUMEN

OBJECTIVES: To evaluate gender-based differences in narrative letters of recommendation (NLORs) and standardized letters of recommendation (SLORs) submitted for applicants to an otolaryngology head and neck surgery (OHNS) residency program. STUDY DESIGN: Retrospective review. METHODS: Nine hundred fifty-eight letters of recommendation (LORs) submitted to one OHNS program in 2013 to 2014 were analyzed. RESULTS: NLORs (n = 590) and SLORs (n = 368) were reviewed. Male writers composed over 85% of all LORs. Compared with male writers, female writers of LORs were more likely to compose a letter of minimal assurance (P < 0.025). Female writers of SLORs were more likely to rank applicants higher in communication skills (P < 0.035) and match potential (P < 0.045). Analysis of LORs by applicant gender revealed that female applicants were more likely than male applicants to be described as team players (P < 0.025) and less likely to receive a letter of minimal assurance (P < 0.001). Compared with SLORs, NLORs written for male applicants were more likely to reference their leadership potential (P < 0.001). Female applicants were less likely to be described as "bright" (P < 0.001) and more likely to have their appearance mentioned (P < 0.03) in NLORs when compared to SLORs. CONCLUSION: Although we found that SLORs reduce gender biases compared to NLORs, there remain significant differences in how female and male applicants are described. Greater awareness of historical biases likely has contributed to more equitable letter writing, although impactful gender biases remain when reviewing applicants. LEVEL OF EVIDENCE: NA.

RESUMEN

PURPOSE: Head and neck soft tissue sarcoma (HNSTS) is a distinct entity within the soft tissue sarcoma group and the evidence supporting treatment options for this disease is poorly defined. Using the National Cancer Database, this study aims to reveal adjuvant therapy utilization patterns and their outcomes. MATERIALS: HNSTS patients constituted 6.5% of all sarcoma patients and the analysis was limited to non-metastatic patients who underwent resection between 2004 and 2012. Chi-square test assessed the distribution of demographic, tumor and treatment variables in the treatment subgroups. Kaplan-Meier method estimated overall survival and proportional hazards model estimated survival hazard ratios for prognostic factors including age, comorbidity, gender, race, size, grade, margin status, histology, chemotherapy administration and radiotherapy technique/dose. RESULTS: The cohort included 2493 patients with a median age of 62years. Adjuvant therapies were more frequently delivered in high-grade, large tumors and with positive surgical margins. Limiting the analysis to 788 high-grade HNSTS patients, adjunctive radiotherapy improved 5-year survival from 44% (95% confidence interval (CI): 38-50) to 49% (CI: 43-55); reducing mortality hazards ratio by 24% (p<0.001). On multivariate analysis, older age, positive surgical margins and large tumor size were significant predictors of poor survival. These findings were consistent after propensity score analysis. CONCLUSION: Our analysis suggests that adjuvant radiotherapy is associated with improved survival in high-grade HNSTS. Higher dose and precise technique did not accentuate this benefit; however, further studies are needed to refine the treatment strategies, including the role of chemotherapy in the management of this rare disease.

RESUMEN

Surgical debridement of medication-related osteonecrosis of the jaw (MRONJ) lesions is far less predictable than lesion resection. Margins for surgical debridement are guided by surrogate markers of bone viability, such as bleeding and bone fluorescence, which limit debridement to visibly necrotic bone. In contrast, surgical resection is extensive, including a substantial portion of surrounding bone. The concept that the MRONJ lesion is a composite of affected but viable ("compromised") and necrotic bone is supported by histopathological data. Hence, removing only the necrotic bone during lesion debridement could inadvertently leave behind residual compromised bone in the lesion, subsequently contributing to persistence or reestablishment of the lesion. Using 2 case reports, this manuscript illustrates a novel assessment of the MRONJ lesion to enable demarcation of both the compromised and necrotic portions of the lesion. This assessment uses tumor-surveillance functional bone imaging data that may already be available for cancer patients with MRONJ and fuses these data digitally with computed tomography/cone-beam computed tomography imaging of the jaw obtained during MRONJ assessment. If validated, preoperative functional imaging-based assessment of the MRONJ lesion could enable surgeons to eliminate both the compromised and nonviable portions of the lesion precisely with conservative debridement, matching surgical resection in outcome.

RESUMEN

Neuronal stimulation improves physiological responses to infection and trauma, but the clinical potential of this strategy is unknown. We hypothesized that transdermal neural stimulation through low-frequency electroacupuncture might control the immune responses to surgical trauma and expedite the postoperative recovery. However, the efficiency of electroacupuncture is questioned due to the placebo effect. Here, electroacupuncture was performed on anesthetized patients to avoid any placebo. This is a prospective double-blinded pilot trial to determine whether intraoperative electroacupuncture on anesthetized patients improves postoperative recovery. Patients with electroacupuncture required 60% less postoperative analgesic, even they had pain scores similar to those in the control patients. Electroacupuncture prevented postoperative hyperglycemia and attenuated serum adrenocorticotropic hormone in the older and heavier group of patients. From an immunological perspective, electroacupuncture did not affect the protective immune responses to surgical trauma, including the induction of interleukin-6 and interleukin-10. The most significant immunological effect of electroacupuncture was enhancing transforming growth factor-ß1 production during surgery in the older and lighter group of patients. These results suggest that intraoperative electroacupuncture on anesthetized patients can reduce postoperative use of analgesics and improve immune and stress responses to surgery.

RESUMEN

BACKGROUND: There is little research documenting the posttreatment experiences and needs of oral/oropharyngeal cancer survivors. METHODS: In this cross-sectional study, 92 patients with oral/oropharyngeal cancer diagnosed between 2 and 5 years prior completed a survey about oral cancer information and support needs. RESULTS: About half retrospectively reported that they did not receive a written treatment summary. The desire for more oral cancer information was common; one-third or more desired more information about long-term effects, recommended follow-up, and symptoms that should prompt contacting a doctor. Support needs were less common; only a lack of energy was rated as a significant support need. Patients who had a recurrence, did not drink alcohol, and had a greater recurrence fear desired more information. Smokers and more distressed patients reported more support needs. CONCLUSION: Survivors reported the desire for more oral cancer information. A desire for assistance was less common. © 2016 Wiley Periodicals, Inc. Head Neck 38: E1935-E1946, 2016.

RESUMEN

OBJECTIVES/HYPOTHESIS: Orbital cellulitis represents a spectrum of diseases, some of which may progress to potentially serious complications. The authors used the Nationwide Inpatient Sample (NIS) database to analyze the epidemiologic features of pediatric and adult patients admitted for the treatment of orbital cellulitis and to examine associations with surgical management. METHODS: The NIS was queried for patients admitted for treatment of orbital cellulitis from 2002 to 2010. Patient demographics, length of stay, hospital charges, and concomitant diagnoses were analyzed. RESULTS: There were 14,149 cases of orbital cellulitis identified with 1,717 (12.1%) having undergone surgical management. Surgical patients were older (29.6 ± 23.4) and more commonly male (62.0%) (P = 0.004 and < 0.001, respectively). Patients who had surgical intervention had longer length of stay and higher hospital charges than nonsurgical patients (P < 0.001). Our study showed that the proportion of pediatric patients age 10 to 19 years (22.1%) undergoing surgery was four times that of patients < 5 years of age (5.1%) (P < 0.001). Patients with concomitant diagnoses of acute and chronic sinusitis, acute osteomyelitis, exophthalmos, diplopia, and conjunctival edema had significantly increased odds ratio of surgical intervention. Frontal sinusitis was the site most commonly associated with surgical intervention among sinusitis patients. CONCLUSION: This study describes the characteristics of pediatric and adult patients admitted for orbital cellulitis from a national perspective. Patients 10 to 19 years of age were most likely to undergo surgical management. Acute and chronic sinusitis, acute osteomyelitis, exophthalmos, diplopia, and conjunctival edema were concomitant diagnoses associated with significantly increased odds ratio of surgical intervention.

RESUMEN

OBJECTIVES/HYPOTHESIS: There are few studies that discuss the issues surrounding emergent awake tracheostomy. We aim to review the indications, anesthesia used, complications, and outcomes of patients undergoing urgent awake tracheostomy. STUDY DESIGN: Chart review. METHODS: Medical charts of patients who underwent an emergent awake tracheostomy at our institution-affiliated tertiary care center over a 5-year period from 2009 to 2014 were reviewed. Data were collected from inpatient, outpatient, and operative records. RESULTS: Sixty-eight patients underwent emergent awake tracheostomy. Over half presented with hoarseness (n=37, 54.4%) and/or stridor (n=37, 54.4%). Acute upper airway obstruction secondary to malignancy was the most common indication and accounted for 58 cases (85.3%). Thirty-nine (70.1%) of the 55 patients with squamous cell carcinoma presented with advanced disease (stage III or IV). Other indications included glottic or subglottic stenosis (4.4%), failure to intubate (2.9%), and other (7.4%). Local anesthesia was used alone in 35.3% of cases and in combination with conscious sedation in 64.7% of cases. Mild bleeding occurred postoperatively in five patients (7.4%). There were no other postoperative complications. Nineteen patients were lost to follow-up. The mean follow-up of 49 patients was 7.2 weeks, ranging from 2 to 261 weeks. Long-term complications occurred in three patients and included tracheitis 7.4% and suprastomal granuloma 2.9%. Eleven patients (22%) were decannulated at a mean of 11.8 months following tracheostomy. CONCLUSIONS: Emergent awake tracheostomy should be considered in patients with impeding airway obstruction and is a safe and effective method to secure an airway in these patients. LEVEL OF EVIDENCE: 4.
