RESUMO

INTRODUCTION: Many theories on the pathophysiology of chronic rhinosinusitis with nasal polyposis (CRSwNP) exist. The most effective management of CRSwNP has not been elucidated. Doxycycline, which has anti-inflammatory and anti-bacterial properties, has shown durable effects; however, its efficacy in combination with standard therapy has not been examined. We hypothesized that its addition to the standard anti-inflammatory regimen would improve patient outcomes. METHODS: We performed a double-blind, placebo-controlled trial at a tertiary level institution. Patients with moderate or severe CRSwNP were randomized into two groups, each receiving a 20-day course of oral corticosteroids and doxycycline or placebo. The 22-item Sinonasal Outcome Test (SNOT-22), nasal polyp scores, and visual analog scale (VAS) scores were recorded at the initial, 3-, 8- and 12-week visits. RESULTS: 49 patients were enrolled, 24 in the experimental and 25 in the placebo group with 3 moderate disease patients in each group. There were 12 dropouts in the treatment group and 14 in the placebo group. The most common reasons for dropout were severe CRS and asthma exacerbations. There was no significant difference in SNOT-22 scores, nasal polyp scores, and VAS scores between the two arms. CONCLUSIONS: Non-surgical management of patients with CRSwNP remains challenging. Our conclusions are limited given the high dropout rate and thus, limited sample size with inadequate power. This study is important, however, because a high dropout rate of mostly severe disease patients may illustrate that this patient population may not be optimally managed with medical therapy alone.

RESUMO

BACKGROUND: Chronic rhinosinusitis (CRS) is a disease of widespread prevalence and high morbidity. Many suggest that the introduction of toxins and allergens via nasal airflow plays a significant role in the development of CRS. In patients who have undergone total laryngectomy, nasal airflow is disrupted, providing an opportunity to examine the role of nasal airflow in sinonasal pathology. METHODS: All patients who received a total laryngectomy between 2002 and 2012 with preoperative and postoperative computed tomography (CT) scans were retrospectively reviewed. The Lund-Mackay (LM) score for each sinus was recorded for both scans. The assessment of differences in pre-operative and post-operative LM scores was analyzed utilizing paired t-tests. RESULTS: 56 patients underwent total laryngectomy and had both preoperative and postoperative CT scans. There were no significant differences in the LM scores between pre-operative and post-operative scans within each sinus (frontal sinus, p = 1.0; anterior ethmoid sinus, p = 0.77; posterior ethmoid sinus, p = 0.45; maxillary sinus, p = 0.90; sphenoid sinus, p = 0.63; ostiomeatal complex, p = 0.78) or in the total LM scores (p = 0.97). Furthermore, patients with pre-operative sinonasal mucosal thickening (total LM score > 0) showed no significant change in their total LM score post-operatively (p = 0.13). CONCLUSION: In total laryngectomy patients, studies demonstrate that a disruption in nasal airflow is correlated to altered sinonasal physiology and decreased subjective symptoms. However, our study shows that the disruption of nasal airflow results in no significant change in radiographic evidence of sinonasal mucosal thickening.

RESUMO

OBJECTIVES: High-resolution microendoscopy (HRME) is an optical imaging modality that allows real time imaging of epithelial tissue and structural changes within. We hypothesize that HRME, using proflavine, a contrast agent that preferentially stains cell nuclei and allows detection of cellular morphologic changes, can distinguish sinonasal pathology from uninvolved mucosa, potentially enabling real-time surgical margin differentiation. STUDY DESIGN: Ex vivo imaging of histopathologically confirmed samples of sinonasal pathology and uninvolved, normal sinus epithelium. SETTING: Single tertiary-level institution. SUBJECTS AND METHODS: Five inverted papillomas, one oncocytic papilloma, two uninvolved sinus epithelia specimens, and three inflammatory polyps were imaged ex vivo with HRME after surface staining with proflavine. Following imaging, the specimens were submitted for hematoxylin and eosin staining to allow histopathological correlation. RESULTS: Results show that sinonasal pathology and normal sinus epithelia have distinct HRME imaging characteristics. Schneiderian papilloma specimens show increased nuclear-to-cytoplasmic ratio, nuclear crowding, and small internuclear separation, whereas normal sinus epithelia specimens show small, bright nuclei with dark cytoplasm and relatively large internuclear separation. Inflammatory polyps, however, have varying imaging characteristics, that resemble both Schneiderian papilloma and normal sinus epithelia. CONCLUSIONS: This study demonstrates the feasibility of HRME imaging to discriminate sinonasal pathology from normal sinus epithelia. While the system performed well in the absence of inflammation, discrimination of inflamed tissue was inconsistent, creating a significant limitation for this application. Novel imaging systems such as HRME with alternative contrast agents may assist with real-time surgical margin differentiation, enabling complete surgical resection of inverted papilloma and reducing recurrence rates.

RESUMO

INTRODUCTION: The mainstay of treatment for primary hyperparathyroidism is surgery. Hypocalcemia after parathyroidectomy is common and poses a significant challenge, leading to increased patient morbidity and health care costs. While several groups have found predictor factors for hypocalcemia, none have created a risk stratification model. Here, we recognize important factors and optimal cut-off values that can allow risk stratification of patients. METHODS: A single-institution retrospective chart review of 339 patients that underwent parathyroidectomy from 2009 to 2012 was conducted. Pre-operative, intra-operative, and post-operative data were collected. A non-routine outcome was defined as post-operative admission, outpatient hypocalcemia-related complication, or inpatient hypocalcemia-related complication. The preoperative or intraoperative factors of patients that experienced a non-routine outcome were compared to those that did not. Optimal cut-off values were determined for preoperative and intraoperative factors and a risk stratification method was created. RESULTS: A total of 39 patients experienced a non-routine outcome including 24 postoperative admissions, 2 inpatient hypocalcemia-related complications, and 17 outpatient hypocalcemia-related complications. Patients with a non-routine outcome displayed a trend toward preoperative hypercalcemia (calcium >11.0mg/dL) than not (p=0.0543). The median preoperative parathyroid hormone (PTH) level was significantly higher among patients with a non-routine outcome (p=0.0037). Furthermore, the median percent decrease in PTH at 20min intraoperatively among patients with a non-routine outcome was significantly higher compared to those that did not (p=0.0421). The optimal cut-off value for preoperative PTH was 129pg/mL and for median percent decrease in intraoperative PTH at 20min was 90.7% for predicting a non-routine outcome. A risk stratification model was created based on these data. CONCLUSION: Our analysis reveals that patients with larger intraoperative decrease in PTH levels (greater than 90.7% drop at 20min), higher preoperative hypercalcemia (greater than 11mg/dL), and higher preoperative PTH levels (greater than 129pg/mL) are more likely to experience a non-routine outcome during outpatient parathyroidectomy. Patients can be risk stratified based on this criteria.

RESUMO

INTRODUCTION: NK/T-cell lymphoma (NKCL), nasal-type is rare in the United States, representing only 1.5% of non-Hodgkin lymphomas. Classically, patients initially present with nasal obstruction (70%), caused by invasion of the localized lesion into the sinuses and nasal cavities. Initial presentation with persistent sore throat and odynophagia due to oropharyngeal tumor extension is rare, and thus, is often overlooked as viral or bacterial pharyngitis. By studying a case of NKTCL nasal type, we emphasize the need to apply high clinical suspicion for NKTCL, nasal type for early diagnosis and improved survival. METHODS: A case report of a rare presentation of NKTCL, nasal-type is discussed. A literature review is provided to define clinical signs crucial for early diagnosis, appropriate work-up, and expedient treatment of this aggressive, rapidly progressive malignancy. RESULTS: In the present case, a 25year-old healthy male presented with a 2-week history of sore throat and odynophagia. On exam, the patient had an ulcerative lesion of the soft palate, an enlarged uvula, and tonsillar exudate with tender submandibular lymphadenopathy. After the patient failed to respond to antibiotic therapy for presumptive pharyngitis, a biopsy of the oropharyngeal tissue was completed, which identified necrotizing sialometaplasia. High clinical suspicion led to repeat deep-tissue biopsy, where a final diagnosis of NKTCL, nasal type was made. The patient then began definitive treatment with chemotherapy and radiation. CONCLUSIONS: High clinical suspicion is key to early diagnosis and improved survival of NKTCL, nasal-type. Otolaryngologists who encounter prolonged, complicated cases of pharyngitis or necrotizing sialometaplasia should consider a diagnosis of NKTCL, nasal-type, in order to prevent rapid disease progression.

RESUMO

BACKGROUND: Nonsurgical rhinoplasty using filler injections has become a common procedure in cosmetic practices. This is offered to patients that prefer a temporary outcome or would like to avoid general anesthesia. In addition, it can be used in postrhinoplasty patients to correct nasal deformities or irregularities. This systematic review highlights common filler types and injection techniques, and associated patient satisfaction and complications to further guide practitioners. METHODS: A systematic review was performed using keywords and Medical Subject Headings search terms. PubMed, EmBase, the Cochrane Library, and Scopus were searched using the appropriate search terms. Data collected from each study included patient satisfaction and complications, in addition to injection material, location, and technique. RESULTS: Four thousand six hundred thirty-two studies were found based on search criteria. After full-text screening for inclusion and exclusion criteria, 23 studies were included. A total of 1600 patients underwent nonsurgical rhinoplasty, most commonly with hyaluronic acid (73.38 percent), followed by calcium hydroxyapatite (12.44 percent). Nearly 95 percent of patients were satisfied with results, and there were only 26 relatively minor complications reported. There were no reports of vascular complications such as skin necrosis or visual compromise. CONCLUSIONS: Based on the authors' review of the literature, nonsurgical rhinoplasty is an effective temporary alternative to traditional augmentation rhinoplasty for corrections of nasal shape with a high degree of patient satisfaction. Complications may be underreported, and thus further investigation is needed to better understand the true incidence of major complications related to vascular compromise.

RESUMO

OBJECTIVE: To examine trends in female author representation within original otolaryngology research between 2000 and 2015. METHODS: Original research articles published in 11 otolaryngology journals were analyzed for 2000, 2003, 2006, 2009, 2012, and 2015. The genders of the first and last authors for each article were recorded. Overall female authorship was calculated by summing the numbers of the first, last, and both first and last female-authored articles. Student t test and Cochran-Armitage trend test were utilized to determine significance between years and groups. RESULTS: Of the 9,623 research articles published during 5 representative years, 223 were excluded due to one or more gender-indeterminate authors. Female first authorship exhibited a significant upward trend from 2000 to 2015 (P < 0.0001), as did the proportion of literature with female first and last authors (P < 0.0001). Although female senior authorship in literature with an impact factor (IF) greater than 2 did not increase significantly (10.0% in 2000 to 10.1% in 2015; P = 0.738), this metric did increase significantly just within journals with an IF between 1 and 2 (9.7%-12.3%, P = 0.036). The proportion of articles with a female author in the first, last, or both positions increased from 28% to 39% (P < 0.0001). CONCLUSION: Increasing female representation in otolaryngology literature may reflect the rising proportion of women within otolaryngology as well as greater mentorship availability. Despite these auspicious strides, female-authored articles nonetheless represent a smaller proportion of the literature, and female senior authors remain a stark minority. Future studies should identify the barriers to female access and advancement within the field. LEVEL OF EVIDENCE: III Laryngoscope, 130:2126-2132, 2020.

RESUMO

Introduction Significant charge disparities exist across New York State (NYS). Race and income are associated with increased charges. To determine risk factor, we correlate hospital charges for pituitary surgery with socioeconomic factors. Additionally, we identify patients at risk for increased hospital charges and provide insight into cost-effective practices. Methods Retrospective cohort study of the Statewide Planning and Research Cooperative System (SPARCS) database from the NYS Department of Health was conducted. The SPARCS database was reviewed. Patients who underwent transsphenoidal pituitary surgery from 1995 to 2015 were identified. Income and urban status were referenced from U.S. census data. Linear regression was performed to analyze the effect of sociodemographic factors, comorbidities, and complications on hospital charges while controlling for length of stay. Results A total of 9,373 patients were identified. Black (10.8%, p < 0.001) and Asian (14.5%, p < 0.001) had higher hospital charges. Patients from nonurban cities (13.4%, p < 0.001), Medicaid (13.8%, p < 0.001), and those from the 0 to 25th (9.1%, p < 0.001) and 25 to 50th (11.7%, p < 0.001) income quartile had lower hospital charges. Patients with postoperative cerebrospinal fluid leak (24.0%, p < 0.001), diabetes insipidus (22.1%, p < 0.001), smoking history (11.8%, p < 0.001), hypertension (7.4%, p < 0.001), and hypothyroidism (6.9%, p < 0.001) had higher hospital charges. Conclusion Patients incurring higher chargers were more likely to have a smoking history, hypertension, hypothyroidism, and comorbidities. The determinants of this analysis may provide insight into barriers to patient access and cost improvement strategies. In addition, this emphasizes the need for future studies to create a risk stratification model, similar to those in other fields.

RESUMO

OBJECTIVES/HYPOTHESIS: The purpose of this study was to compare timing of procedure, patient characteristics, outcomes, and charges for patients who underwent percutaneous versus surgical tracheostomy. STUDY DESIGN: Retrospective cohort study. METHODS: A retrospective analysis was performed for all patients who underwent tracheostomy in 2015 to 2016 in New York State. Patients were identified using International Classification of Diseases, 10th Revision, Clinical Modification codes and stratified to the type of tracheostomy performed. The primary outcome of interest was mortality at index stay. Secondary outcomes of interest included length of stay and total hospitalization charges. RESULTS: Of the 8,682 patients, 2,488 (28.7%) underwent percutaneous and 6,194 (71.3%) underwent surgical tracheostomy. At hospitals where both procedures were performed, percutaneous tracheostomy patients were older, had more comorbidities, and had lower income (P < .05). Timing of the tracheostomy relative to admission did not affect the type of tracheostomy performed. While controlling for patient characteristics and complications during the visit, percutaneous tracheostomy was associated with increased mortality (odds ratio [OR]: 1.17, 95% confidence interval [CI]: 1.03-1.33, P = .0153) and increased hospital charges (OR: + 7.76%, 95% CI: 5.4-10.11, P < .0001). Length of stay was not affected by procedure type. CONCLUSIONS: Surgical tracheostomies are more commonly performed than percutaneous tracheostomies across New York State. Older, lower-income, and sicker patients have a higher chance of receiving percutaneous tracheostomies. Percutaneous approaches were associated with statistically significant increased mortality and higher charges despite no difference in length of stay. Further studies are needed to determine if these differences in outcomes are clinically significant. LEVEL OF EVIDENCE: NA Laryngoscope, 128:2844-2851, 2018.

RESUMO

Objective To investigate the influence of patient demographic factors and hospital factors on cost and length of stay in patients undergoing pituitary surgery. Design/Setting A retrospective cross-sectional study of the 2008 to 2012 Nationwide/National Inpatient Sample. Participants Patient demographics and hospital characteristics for patients undergoing pituitary surgery were compared between white, black, and Hispanic patients. Main Outcome Measures Variables associated with increased cost and increased length of hospital stay were ascertained and compared against each racial and ethnic group via multiple linear regression analysis. Results Of 8,812 patients who underwent pituitary surgery, 5,924 (67.2%) patients were white, 1,590 (18.0%) were black, and 1,296 (14.7%) were Hispanic. Patient variables found to be significantly different between racial groups via univariate analysis were age, chronic conditions, gender, income, and primary payer. Hospital variables found to be significantly different were location/teaching status, region, and ownership. Hospitalization cost was significantly lower for whites (-$3,082, 95% confidence interval [CI] -$3,961 to -$2,202) and significantly higher for both blacks ($1,889, 95% CI $842-$2,937) and Hispanics ($2,997, 95% CI $1,842-$4,152). Length of hospital stay was also significantly lower in whites (-1.01, 95% CI -1.31 to -0.72) and significantly higher for both blacks (0.65, 95% CI 0.30 to 1.00) and Hispanics (0.96, 95% CI 0.57-1.35). Conclusions Racial and ethnic factors contribute to differences in hospital utilization and cost for patients undergoing pituitary surgery. Further investigations are necessary to uncover the sources of these disparities in an effort to provide safer and more affordable care to all patients.

RESUMO

BACKGROUND: Improvement in topical delivery to nasal mucosa is a fundamental goal of endoscopic sinus surgery (ESS). This study compares the penetration of irrigation before and after middle turbinate resection (MTR) to assess the efficacy of topical delivery. METHODS: ESS was performed on 4 cadaver heads, followed by MTR. Each head was irrigated with fluorescein-dyed water using a squeeze bottle both before and after MTR. Videos were recorded by rigid nasal endoscopy. Four blinded raters reviewed videos and scored the extent of staining (0 to 3) for each site. RESULTS: The mean score for the extent of staining of all anatomical sites before and after MTR was 1.30 and 1.92, respectively (p = 0.035). The mean score for extent of staining before and after MTR was 2.56 and 2.81 (p = 0.134) for the maxillary sinus, 1.66 and 2.25 (p = 0.022) for the ethmoid sinus, 1.03 and 1.94 (p = 0.263) for the sphenoid sinus, 0.16 and 0.94 (p = 0.055) for the frontal sinus, and 1.09 and 1.66 (p = 0.340) for the olfactory cleft, respectively. When evaluating interrater reliability, Cronbach's alpha was 0.92, which is acceptable. When evaluating intrarater reliability, the Fleiss kappa statistic for each rater was excellent or good. CONCLUSION: Overall, MTR results in significant improvement in the penetration of nasal irrigations in the cadaver model. Each individual sinus displays a trend toward improvement; however, only the ethmoid sinus displays a statistically significant improvement. Further in vivo studies are needed to elucidate the role of MTR.

RESUMO

OBJECTIVE: Contralateral reactive lesions (RLs) represent a distinct entity among benign bilateral vocal fold (VF) lesions. Lack of uniform nomenclature and a myriad of surgical options have hampered attempts to develop treatment guidelines. The objective of this study is to better define RLs and their prognosis, through the development of a standard nomenclature, with an aim to guide treatment and delineate the role of phonosurgery. STUDY DESIGN: Case series with chart review. SETTING: Tertiary care center. SUBJECTS AND METHODS: Analysis was performed on patients with Current Procedural Terminology code 31545. Operative reports with a primary lesion and contralateral RL were included. Outcomes included the Voice Handicap Index-10 (VHI-10) and GRBAS (grade, roughness, breathiness, asthenia, and strain) scale, lesion persistence/recurrence, mucosal wave, and edge character based on blinded videostroboscopy review. RESULTS: A nomenclature was developed based on intraoperative RLs (n = 30), defined by lesion consistency (fibrous or polypoid) and relationship to normal VF edge (gradual or steep). Reactive lesion treatment included no intervention, excision, potassium titanyl phosphate laser, steroid injection, or a combination thereof. Observations included the following: inconsistent treatment modalities were employed, excision of RLs did not yield better outcomes, fibrous RLs were more likely to persist and polypoid lesions more likely to recur, gradual lesions were more likely to remain disease free, and most treatments showed improved mucosal wave, VHI-10, and GRBAS. CONCLUSIONS: Reactive lesions have not been well classified, and treatments are based on subjective intraoperative decision making with unpredictable outcomes. The nomenclature proposed will allow for a better definition of the RL and provide a framework for future research to identify optimal treatment.

RESUMO

BACKGROUND: High-resolution microendoscopy (HRME) enables real-time imaging of epithelial tissue. The utility of this novel imaging modality for inverted papilloma has not been previously described. This study examines the ability of otolaryngologists to differentiate between images of inverted papilloma and normal sinonasal mucosa obtained with a HRME. METHODS: Inverted papilloma and normal sinonasal mucosa specimens were stained with a contrast agent, proflavine. HRME images were subsequently captured. Histopathological diagnosis was obtained for each sample. Quality-controlled images were used to assemble a training set. After reviewing the training images, 6 otolaryngologists without prior HRME experience reviewed and classified test images. RESULTS: Five samples of inverted papilloma and 2 normal sinonasal mucosa samples were collected. Four representative images from each specimen were used for the 28-image test set. The mean accuracy among all reviewers was 89.9% (95% confidence interval [CI], 84.3% to 94.0%). The sensitivity to correctly identify inverted papilloma was 86.7% (95% CI, 79.2% to 92.2%), and the specificity was 92.9% (95% CI, 89.0% to 100.0%). The Fleiss kappa interrater reliability score was 0.80 (95% CI, 0.70 to 0.89). CONCLUSION: Inverted papilloma and normal sinonasal mucosa have distinct HRME imaging characteristics. Otolaryngologists can be successfully trained to distinguish between inverted papilloma and normal sinonasal mucosa. HRME is a feasible tool for identification of inverted papilloma. By conducting future in vivo trials, HRME potentially may enable real-time surgical margin determination during surgical excision of inverted papilloma.
