International pediatric otolaryngology group (IPOG) consensus on approach to aspiration.

OBJECTIVE: To provide recommendations for a comprehensive management approach for infants and children presenting with symptoms or signs of aspiration. METHODS: Three rounds of surveys were sent to authors from 23 institutions worldwide. The threshold for the critical level of agreement among respondents was set at 80 %. To develop the definition of "intractable aspiration," each author was first asked to define the condition. Second, each author was asked to complete a 5-point Likert scale to specify the level of agreement with the definition derived in the first step. RESULTS: Recommendations by the authors regarding the clinical presentation, diagnostic considerations, and medical and surgical management options for aspiration in children. CONCLUSION: Approach to pediatric aspiration is best achieved by implementing a multidisciplinary approach with a comprehensive investigation strategy and different treatment options.

Associations of deep sleep and obstructive sleep apnea with family relationships, life satisfaction, and physical stress experience in children: a caregiver perspective.

STUDY OBJECTIVES: Obstructive sleep apnea (OSA) and poor quality of sleep negatively impacts health-related quality of life in adults, but few studies have evaluated the association between sleep disturbance (eg, OSA, inadequate sleep) and health-related quality of life domains (eg, family relations, life satisfaction) in children. METHODS: Children ages 8-17 years referred to a sleep center for routine polysomnography from April 2022 to August 2022 were approached to participate in the study, and children visiting the department of pediatrics for their wellness visit were recruited for comparisons. Statistical analysis was conducted using R 3.6.0. RESULTS: Ninety-nine children were recruited from the sleep clinic, and 23 children were recruited from the primary care clinic. Of these children, 62 were diagnosed with obstructive sleep apnea (31 mild, 12 moderate, 19 severe), and 37 did not meet criteria for a diagnosis. Health-related quality of life domains did not differ across OSA severity levels. Children in general had lower life satisfaction and higher physical stress experience compared to children visiting for their wellness examination (well-child visitors, P = .05 and P = .005, respectively). Children with severe OSA had significantly lower life satisfaction and significantly higher physical stress experience when compared with well-child visitors (P = .008 and P = .009, respectively). Correlation analysis showed that N3 (deep) sleep was positively associated with family relations and life satisfaction, while it was negatively associated with anger. CONCLUSIONS: Based on caregiver response, N3 sleep is positively associated with family relations and life satisfaction and negatively associated with anger. Severe OSA is associated with lower life satisfaction and higher physical stress experience. CITATION: Bhushan B, Zee PC, Grandner MA, et al.

Fiberoptic Endoscopic Evaluation of Swallowing in the Breastfeeding Infant.

OBJECTIVE: To demonstrate the importance of utilizing fiberoptic endoscopic evaluation of swallowing (FEES) when evaluating breastfeeding infants with suspected dysphagia. Failure to recognize and account for the fundamentally different physiology of the primarily breastfed infant can lead to false assumptions about the safety of breastfeeding in this understudied patient population. METHODS: Case-series. The medical records of patients referred to an urban, university-based, pediatric hospital for FEES from February 2017 to October 2020 were reviewed. Their presenting symptoms, dysphagia severity, comorbidity, dysphagia workup, and management were analyzed. The standardized Dysphagia Outcome and Severity Scale was used to appraise dysphagia severity. RESULTS: 204 FEES exams were reviewed. 35 were conducted on breastfed infants. 34 of the 35 infants calmed for the FEES exam while breastfeeding. Cohorts were defined by a particular presenting sign (cough, laryngeal congestion, choking, and respiratory illness) and anatomical characteristic (laryngomalacia, vocal cord paralysis, aspiration, penetration, etc.) and then compared to all other exams. The average dysphagia score for all the exams was 2.37. Patients presenting with laryngeal congestion had an average dysphagia score of 2.81. There was no difference in dysphagia score based on comorbidities or anatomy. CONCLUSIONS: FEES is the instrumental exam of choice when evaluating a primarily breastfed infant who has suspected dysphagia. The exam is well tolerated and provides accurate, objective information while accounting for this population's unique swallowing physiology. Primarily breastfed infants presenting with laryngeal congestion are more likely to have clinically worse dysphagia than those presenting with other clinical symptoms. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:2803-2807, 2023.

Evaluating dysphagia in infants with congenital heart disease using Fiberoptic Endoscopic Evaluation of Swallowing.

OBJECTIVE: Dysphagia is common in infants with congenital heart disease (CHD). However, there is minimal published data regarding its management outside of the perioperative period. The objective of this study is to describe the role of Fiberoptic Endoscopic Evaluation of Swallowing (FEES) in the diagnosis and management of dysphagia in infants with CHD. METHODS: Infants with CHD who underwent FEES exam for evaluation of swallowing dysfunction between February 2015 and February 2021 at a university-based, tertiary care urban pediatric hospital were studied. Demographic data, presenting symptoms, medical history, and dysphagia history were examined. The validated Dysphagia Outcome and Severity Scale (DOSS) was used to standardize and compare dysphagia severity. RESULTS: 62 FEES exams were performed on 48 patients. All 48 patients were diagnosed with dysphagia and had a mean dysphagia severity score (DOSS) of 2.68. Patients with wet laryngeal congestion on presentation had worse mean DOSS score and were more likely to demonstrate aspiration on FEES exam (p < 0.01). There was no significant difference in mean DOSS or presence of aspiration when comparing infants who had cardiothoracic surgery, vocal cord paralysis, or lower respiratory tract illness with those who had not (p > 0.05). CONCLUSION: A FEES exam is an effective and well-tolerated procedure for evaluating swallowing dysfunction in pediatric patients with CHD and its use reduces radiation exposure for this vulnerable population. Wet laryngeal congestion was found to be predictive of more severe dysphagia and aspiration. There is no significant association between severity of dysphagia or aspiration on FEES exam and history of cardiac surgery, vocal cord paralysis, or lower respiratory tract illness.

Fiberoptic Endoscopic Evaluation of Swallowing Across the Age Spectrum.

Purpose Fiberoptic endoscopic evaluation of swallowing (FEES) is a widely used instrumental procedure used to assess swallowing function in persons of all ages, from infants to older adults. In this article, the history of FEES in adults, the protocol, the scoring system, and the interpretation of abnormal findings are summarized. The use of FEES to guide treatment in adults is also covered briefly. Following this review in adults, the use of FEES in infants and children is presented, including the anatomical-physiological assessment and the assessment of swallowing of food and liquid. Interpretation of findings and therapeutic applications are discussed. Conclusion FEES is a valuable part of the clinical protocol for evaluation and management of dysphagia across the life span. It provides a mechanism for in-depth analysis of swallowing structures and function during intake of liquid and food boluses. Future developments include standardized training content to ensure clinical competency and the development of standardized examination and interpretation protocols.

Polysomnography Outcomes after Supraglottoplasty in Children with Obstructive Sleep Apnea.

OBJECTIVE: Laryngomalacia has been reported to contribute to the severity of obstructive sleep apnea (OSA) in children. It is unclear if surgical treatment of laryngomalacia improves polysomnography (PSG) outcomes in these patients. The objective of this study is to report the impact of supraglottoplasty on PSG parameters in children with laryngomalacia-related OSA. STUDY DESIGN: Retrospective case series. SETTING: Tertiary care medical center. SUBJECTS AND METHODS: Historical cohort study of consecutive children with laryngomalacia who underwent supraglottoplasty and who had undergone overnight PSG before and after surgery. RESULTS: Forty-one patients were included in the final analysis: 22 (53.6%) were male, and 19 (46.3%) were female. The mean ± SEM age of patients at preoperative PSG was 1.3 ± 0.89 years (range, 0.003-2.9). In entire cohort, the mean obstructive apnea-hypopnea index score was reduced from 26.6 events/h before supraglottoplasty to 7.3 events/h after surgery (P = .003). Respiratory disturbance index was reduced from 27.3 events/h before supraglottoplasty to 7.8 events/h after surgery (P = .003). The percentage of REM sleep decreased from 30.1% ± 2.4 to 24.8% ± 1.3 (P = .04). Sleep efficiency was improved (P = .05). CONCLUSION: Overall, supraglottoplasty significantly improved several PSG outcomes in children with laryngomalacia. However, mild to moderate OSA was still present postoperatively in most children. This suggested a multifactorial cause for OSA in this population.

A Chronic Glottic Foreign Body Diagnosed by Radiograph after 9 Months of Symptoms.

A six-year-old girl presented to an emergency room after describing choking on a rubber band. She was in no distress and was discharged. Over the course of the next 9 months, she had numerous outpatient and emergency room visits due to intermittent stridor, difficulty breathing, and hoarseness. Eventually, dedicated airway films revealed a laryngeal foreign body. During rigid bronchoscopy, a two-centimeter rubber band was discovered in the larynx. It extended from the supraglottis, through the glottis, and into the subglottis. It was successfully removed. The patient was asymptomatic 24 hours later. This case highlights the appropriate evaluation and management of a child with stridor.

Five year follow-up after autologous peripheral blood hematopoietic stem cell transplantation for refractory, chronic, corticosteroid-dependent systemic lupus erythematosus: effect of conditioning regimen on outcome.

Some patients with systemic lupus erythematosus (SLE) are refractory to traditional therapies, dependent on chronic corticosteroids, have organ damage, and are at high risk of mortality. In this group of patients, we report outcome at a median of five years after autologous hematopoietic stem cell transplant (HSCT) using two different non-myeloablative regimens. Four patients received a conditioning regimen of cyclophosphamide (200 mg/kg) and alemtuzumab (60 mg), while 26 patients underwent conditioning with cyclophosphamide (200 mg/kg), rATG (Thymoglobulin) (5.5 mg/kg), and rituximab 1000 mg. Unselected peripheral blood stem cells were infused on day 0. There were no treatment related deaths. Of the four patients treated with cyclophosphamide and alemtuzumab, none entered remission. For the 26 patients treated with cyclophosphamide, rATG, and rituximab, disease remission defined as no immune suppressive drugs except hydroxychloroquine and/or 10 mg or less of prednisone a day was 92% at 6 months, 92% at one year, 81% at 2 years, 71% at 3 years, and 62% at 4 and 5 years post-HSCT. Autologous HSCT outcome is dependent on the conditioning regimen but prior organ damage may cause lingering symptoms.

The "Surgeon on Service" Model for Timely, Economically Viable Inpatient Care of Tracheostomy Patients in Academic Pediatric Otolaryngology.

Importance: The traditional practice model for pediatric otolaryngologists at high-volume academic centers is to simultaneously balance outpatient care responsibilities with those of the inpatient service, emergency department, and ambulatory care clinics. This model leads to challenges with care coordination, timeliness of nonemergency operative care, and consistent participation in care and consultation at the attending surgeon level. The "surgeon on service" (SOS) model-where faculty members rotate to manage the inpatient service in lieu of outpatient responsibilities-has been described as one method to address this conundrum. The operational and economic feasibility of the SOS model has been demonstrated; however, its impact on care coordination, time from consultation to surgical care, and length of stay (LOS) have not been evaluated. Objective: To determine the impact of the SOS model on the quality principles of timeliness and efficiency of tracheostomy tube placement and to determine if the SOS model is fiscally feasible in an academic pediatric otolaryngology practice. Design, Setting, and Participants: Medical record review of patients undergoing tracheostomy in a pediatric academic medical center and survey of their treating physician trainees, comparing the 6-month SOS pilot phase (postimplementation, January-June 2016) with the 6-month preimplementation period (January-June 2015). Intervention: Implementation of the SOS model. Main Outcomes and Measures: Time to tracheostomy, frequency of successful coordination of tracheostomy with gastrostomy tube placement, total LOS, productivity measured in work relative value units, and responses to trainee surveys. Results: Of the 41 patients included in the study (24 boys and 17 girls; mean age, 3 years; range, 3 months to 17 years), 15 were treated before SOS implementation, and 26 after. Also included were 21 trainees. Before SOS implementation, median time to tracheostomy was 7 days (range, 2-20 days); after SOS implementation, it was 4 days (range, 1-10 days) (difference between the medians, before to after, -3 days; 95% CI, -5 to 0 days). There was no significant difference in overall LOS or ability to coordinate tracheostomy with gastrostomy tube placement. Preimplementation trainee surveys cited dissatisfaction with the communication channels to the primary team when the consulting surgeon was not immediately available to perform tracheostomy. No challenges were reported after implementation. Productivity was comparable to that in the outpatient setting. Conclusions and Relevance: In this study, the presence of a rotating inpatient pediatric otolaryngologist was a productive approach to patient care associated with more timely performance of tracheostomy. Other benefits were an improved balance of service with education to trainees and a better perception of communication with consulting services.

Jaw Rotation in Dysarthria Measured With a Single Electromagnetic Articulography Sensor.

PURPOSE: This study evaluated a novel method for characterizing jaw rotation using orientation data from a single electromagnetic articulography sensor. This method was optimized for clinical application, and a preliminary examination of clinical feasibility and value was undertaken. METHOD: The computational adequacy of the single-sensor orientation method was evaluated through comparisons of jaw-rotation histories calculated from dual-sensor positional data for 16 typical talkers. The clinical feasibility and potential value of single-sensor jaw rotation were assessed through comparisons of 7 talkers with dysarthria and 19 typical talkers in connected speech. RESULTS: The single-sensor orientation method allowed faster and safer participant preparation, required lower data-acquisition costs, and generated less high-frequency artifact than the dual-sensor positional approach. All talkers with dysarthria, regardless of severity, demonstrated jaw-rotation histories with more numerous changes in movement direction and reduced smoothness compared with typical talkers. CONCLUSIONS: Results suggest that the single-sensor orientation method for calculating jaw rotation during speech is clinically feasible. Given the preliminary nature of this study and the small participant pool, the clinical value of such measures remains an open question. Further work must address the potential confound of reduced speaking rate on movement smoothness.

Clinical symptoms that predict the presence of Obstructive Sleep Apnea.

OBJECTIVE: To determine if a set of clinical symptoms can help in determining the presence and severity of OSA. SETTING: Tertiary urban pediatric hospital. METHODS: Parents of children undergoing an overnight PSG answered a 56 item questionnaire based on their child's symptoms. The responses to the questionnaire were compared between patients with different severities of OSA (s determined by PSG) and those without OSA. Responses to questionnaire were also analyzed between obese and non-obese patients. RESULTS: 235 children were included (140 male and 95 female) with a mean age of 5.76 ± 2.78 years. The mean Apnea Hypopnea Index (AHI) was 7.78 ± 14.50 events/hour (range 0-110 events/h). 74 (31.5%) children had mild-OSA (AHI between 1 and 4.99 events/h), 31 (13.19%) had moderate-OSA (AHI between 5 and 9.99 events/h), 58 (24.7%) had severe-OSA (AHI≥10events/h) and the remaining 72 (30.64%) had No-OSA (AHI≤1event/h). 87 (37%) patients were obese. Eight clinical symptoms in non-obese and six clinical symptoms in obese patients predicted the mild to severe OSA. Sixteen symptoms in non-obese patients and nine symptoms in obese patients predicted the presence of severe OSA in these patients. CONCLUSION: Clinical symptoms reported in this study are useful to predict the presence of and the severity of OSA in children. Clinical symptoms can also predict the presence and severity of OSA in children who are obese, however, the symptoms required to make the prediction are different in obese children.

Development of the maxillary sinus in infants and children.

OBJECTIVE: To examine the age related volume change of the maxillary sinus in children by measuring the change of the height, weight, and depth using computed tomography (CT). METHODS: Children <18 years of age who underwent a CT Scan of the sinuses for reasons other than sinus related issues were included in the study. RESULTS: 139 patients were included (68 females and 71 Males) and the mean age of the patients was 9.6 ± 5.4 years. The cohort was divided into three groups based on their ages - Age <6 years (n = 45), age between 6 and 12 years (n = 44) and age > 12 years (n = 50). Patients in each age group demonstrated an increase in their Maxillary sinus height (p<0.001). Patients < 6years of age and between 6 and 12 years of age had a significant increase in their maxillary sinus width and depth (p < 0.001). The maxillary sinus width, depth and volume did not increase significantly after the age of 12 years in these patients. CONCLUSION: We demonstrated periods of significant size increase of the maxillary sinuses as determined by different dimensions in children at various ages. The height of the maxillary sinus has steady growth from birth to at least the age of 18 years. The width and depth increase up to 12 years of age.

Antibiotic Prescribing by Physicians Versus Nurse Practitioners for Pediatric Upper Respiratory Infections.

BACKGROUND: This study investigates differences in antibiotic prescribing rates for pediatric upper respiratory infections (URIs) between physicians and nurse practitioners (NPs). METHODS: Visits by children <18 years old diagnosed with URI to physicians or NPs between 2001 and 2010 were abstracted from the National Ambulatory Medical Care Survey and National Hospital Ambulatory Care Survey. Logistic regression analyses examined variations in antibiotic prescribing rates. RESULTS: Upper respiratory infections accounted for approximately 439 ± 21.5 million visits. Patients seen by NPs were more likely to have Medicaid, live in the lowest median household income quartile zip codes and micropolitan locations, and live in the South compared to patients seen by physicians. Nurse practitioners prescribed antibiotics 66.7% ± 4.2% of the time versus physicians at 52.8% ± 0.8% for URI visits (unadjusted P-value = .002). Adjusted by specialty, URI type, and chronic diseases, NPs had marginally significantly different odds of prescribing antibiotics (OR = 1.6, 95% CI, 1.0-2.6, P-value = .048), but the association with prescribing broad-spectrum antibiotics is not as strong (adjusted P-value = .063). Patient visits to a pediatric (OR = 0.54, 95% CI, 0.43-0.67) or ENT/surgery practice (OR = 0.11, 95% CI, 0.06-0.18) had lower odds of antibiotic prescribing compared to general/family medicine practices. Year (2001-2010) was not significantly associated with antibiotic or broad-spectrum antibiotic prescribing rates for physicians, but rates for NPs fell for otitis media (P-value = .007) from 90.2% ± 8.2% (2001-2002) to 74.8% ± 6.8% (2009-2010) of visits. CONCLUSIONS: Nurse practitioners have higher rates of antibiotic prescribing compared to physicians for pediatric patients with URIs; however, this difference is less after adjusting for specialty. Examining comparative antibiotic prescribing is important to promote evidence-based practice and adoption of clinical guidelines.

The impact of delayed surgical drainage of deep neck abscesses in adult and pediatric populations.

OBJECTIVES/HYPOTHESIS: The conventional treatment for deep neck abscesses in adults is antibiotic therapy with surgical drainage, whereas in children there is debate about the role of surgical drainage versus conservative therapy. It is presently unclear if delayed surgical drainage negatively affects outcomes. STUDY DESIGN: We performed a multicenter, prospective, risk-adjusted cohort study of adult and pediatric patients with deep neck abscess who received incision and drainage within 7 days of admission in the American College of Surgeons National Surgical Quality Improvement Program from 2005 to 2013 (adults) and from 2012 to 2013 (pediatrics). METHODS: Patients were compared based on age (≤ 18 years, > 18 years), timing of surgical drainage (day 0, day 1-2, or day 3-7), and complication rates (specifically, abscess-specific morbidity and mortality [M&M]). Multivariate regression was performed to control for preoperative differences. RESULTS: A total of 1,012 cases of deep neck abscess were identified (347 adult, 665 pediatric). In adults, delay in surgical drainage was associated with increased abscess-specific M&M, from 11.5% (day 0) to 17.3% (day 1-2) to 25.0% (day 3-7) (P = 0.02). On multivariate regression, delay in drainage of ≥ 3 days in adults was associated with a 2.38-fold increase in M&M (95% confidence interval 1.01-5.59, P = 0.019). In pediatrics, there was no association between surgical delay and increased abscess-specific M&M, with rates of 5.0% (day 0), 4.0% (day 1-2), and 4.8% (day 3-7) (P = 0.68). CONCLUSION: In adults, delay in surgical drainage of deep neck abscess is associated with increased M&M. There is no association between timing of drainage and M&M in children. LEVEL OF EVIDENCE: 2c.

Fiberoptic examination of swallowing in the breastfeeding infant.

OBJECTIVES/HYPOTHESIS: Fiberoptic endoscopic evaluation of swallowing (FEES) is the only instrumental exam that can be used to assess swallowing in a breastfeeding infant. There is minimal data on its efficacy and safety in this patient population. Analyze the common indications for, findings of, and safety of FEES exam in breastfeeding infants. STUDY DESIGN: Case series. METHODS: Consecutive 10 months old or younger breastfed infants undergoing a FEES exam between June 1, 2012, and August 1, 2014, at a university-based, tertiary care urban children's hospital were studied. Common indications for and findings of FEES, as well as complications of the procedure, were determined. RESULTS: Twenty-four FEES were reviewed on 23 patients. There were 14 males (58%). The average age was 14 weeks, and two children were premature. Common indications for FEES were feeding difficulties (52%), noisy breathing with/without feeding (28%), and cyanosis (16%). Of the patients who participated in active breastfeeding during the exam, a functional swallow was identified in 12.5%. The remaining patients demonstrated dysphagia characterized by laryngeal penetration (83%) and/or direct aspiration (50%). The most common findings were laryngeal edema (29%), anterior displacement of glottis structures (14%), and cobblestoning (11%). There was no morbidity directly associated with the procedure. No cyanosis or respiratory distress occurred during or immediately after the procedure. CONCLUSION: Performing FEES exams on breastfeeding infants is safe and effective. There is no other instrumental evaluation of swallowing to assess dysphagia in this population. LEVEL OF EVIDENCE: 4. Laryngoscope, 126:1681-1686, 2016.

Cost effective use of audiograms after pediatric temporal bone fractures.

OBJECTIVE: To identify the relationship of pediatric temporal fractures to the incidence and type of hearing loss present. To analyze the timing and utility of audiometric testing in children with temporal bone fractures. METHODS: Retrospective case series of 50 pediatric patients with temporal bone fractures who were treated at an urban, tertiary care children's hospital from 2008 to 2014. A statistical analysis of predictors of hearing loss after temporal bone fracture was performed. RESULTS: Fifty-three fractures (69.7%) in 50 patients involved the petrous portion of the temporal bone. The mean age of patients was 7.13 years, and 39 (73.6%) were male. A fall was the most common mechanism of injury in 28 (52.8%) patients, followed by crush injury (n=14, 26.2%), and vehicular trauma (n=10, 18.9%). All otic capsule violating fractures were associated with a sensorineural hearing loss (n=4, 7.5%, p=0.002). Three of four otic capsule sparing fractures were associated with ossicular dislocation, with a corresponding mixed or conductive hearing loss on follow up audiometric testing. The majority of otic capsule sparing fracture patients (n=19/43, 44.2%) who had follow up audiograms had normal hearing, and those with otic capsule violating fractures were statistically more likely to have persistent hearing loss than those with otic capsule sparing fractures (p=0.01). CONCLUSIONS: Patients with otic capsule violating fractures or those with ossicular disruption are at higher risk for persistent hearing loss. Cost-saving may be accrued by selecting only those patients at high risk for persistent hearing loss for audiometric testing after temporal bone fractures.

Preliminary data using computed tomography texture analysis for the classification of hypervascular liver lesions: generation of a predictive model on the basis of quantitative spatial frequency measurements--a work in progress.

OBJECTIVE: Computed tomography texture analysis (CTTA) is a method of quantifying lesion heterogeneity based on distribution of pixel intensities within a region of interest. This study investigates the ability of CTTA to distinguish different hypervascular liver lesions and compares CTTA parameters by creating a proof-of-concept model to distinguish between different lesions. METHODS: Following institutional review board approval, CTTA software (TexRAD Ltd) was used to retrospectively analyze 17 cases of focal nodular hyperplasia, 19 hepatic adenomas, 25 hepatocellular carcinomas, and 19 cases of normal liver parenchyma using arterial phase scans. Two radiologists read the same image series used by the CTTA software and reported their best guess diagnosis. Computed tomography texture analysis parameters were computed from regions of interest using spatial band-pass filters to quantify heterogeneity. Random-forest method was used to construct a predictive model from these parameters, and a separate regression model was created using a subset of parameters. RESULTS: The random-forest model successfully distinguished the 3 lesion types and normal liver with predicted classification performance accuracy for 91.2% for adenoma, 94.4% for focal nodular hyperplasia, and 98.6% for hepatocellular carcinoma. This error prediction was generated using a subset of data points not used in generation of the model, but not on discrete prospective cases. In contrast, the 2 human readers using the same image series data analyzed by the CTTA software had lower accuracies, of 72.2% and 65.6%, respectively. The explicit regression model with a subset of image parameters had intermediate overall accuracy of 84.9%. CONCLUSIONS: Computed tomography texture analysis may prove valuable in lesion characterization. Differentiation between common hypervascular lesion types could be aided by the judicious incorporation of texture parameters into clinical analysis.

Trends in the management of pediatric peritonsillar abscess infections in the U.S., 2000-2009.

OBJECTIVES: To analyze temporal trends in the incidence and surgical management of children with peritonsillar abscesses (PTAs), and to examine whether there has been concurrent changes in hospital charges or length of stay. METHODS: The Kids' Inpatient Database (KID) from 2000 to 2009 was examined for children less than 18 years old with ICD-9-CM diagnostic codes for PTA (475). Survey weighted frequency and regression analyses were performed across the entire study period on variables of interest in order to determine estimates of national incidence, demographics and outcomes. RESULTS: A total of 20,546 weighted cases of PTA were identified during the study period. There was no significant change in the incidence of pediatric PTA across the study period (p=0.63) or in the rate of nonsurgical management (p=0.85). There was a significant increase in the rates of I&D from 26.4% to 33.7% (p<0.001) and a significant decrease in the rate of tonsillectomy from 13.0% to 7.8% (p<0.001). Mean inflation-adjusted charges significantly increased from approximately $8400 in 2000 to $13,300 in 2009 (p<0.001), and average length of stay was 2.15 days with no significant change during the study period (p=0.164). Mean inflation-adjusted charges for patients undergoing tonsillectomy alone were approximately $1800 greater than mean charges for those undergoing I&D alone (p=0.003) and length of stay was also significantly longer for tonsillectomy patients versus I&D patients [I&D 1.99 days versus tonsillectomy 2.23 days (p<0.001)]. CONCLUSIONS: There was no change in the incidence of pediatric PTAs from 2000 to 2009 but there was a change in surgical management, with a significant decrease in the rate of tonsillectomy and significant increase in the rate of incision and drainage procedures. Hospital charges during this period increased nearly 60% despite no change in rates of CT imaging, surgical intervention or length of stay.

Prenatal diagnosis of obstructive head and neck masses and perinatal airway management: the ex utero intrapartum treatment procedure.

Advances in prenatal imaging in the last 20 years have enabled prenatal diagnosis of obstructive head and neck masses. These advances, coupled with improvements in maternal-fetal anesthesia, have made possible the development of the ex utero intrapartum treatment (EXIT) procedure for management of obstructive head and neck masses, during which the airway is managed in a controlled fashion while maintaining fetal circulation for oxygenation. This review addresses the preoperative and perioperative assessment and management of patients with prenatally diagnosed airway obstruction, indications and contraindications for the EXIT procedure, technical details of the procedure, and outcomes.
