Polysomnographic Characteristics of Sleep Architecture in Children With Obstructive Sleep Apnea.

BACKGROUND: The conventional measure of sleep fragmentation is via polysomnographic evaluation of sleep architecture. Adults with OSA have disruption in their sleep cycles and spend less time in deep sleep stages. However, there is no available evidence to suggest that this is also true for children and published results have been inconclusive. OBJECTIVE: To determine polysomnographic characteristics of sleep architecture in children with OSA and investigate effects relative to OSA severity. METHODS: Overnight polysomnograms (PSG) of children referred for suspected OSA were reviewed. Subjects were classified by apnea hypopnea index (AHI). PSG parameters of sleep architecture were recorded and analyzed according to OSA severity. RESULTS: Two hundred and eleven children were studied (median age of 7.0 years, range 4-10 years) Stage N1 sleep was longer while stage N2 sleep and REM sleep was reduced in the OSA group when compared to those without OSA (6.10 vs 2.9, P < .001; 42.0 vs 49.7, P < .001; 14.0 vs 15.9, P = .05). The arousal index was also higher in the OSA group (12.9 vs 8.2, P < .001). There was a reduction in sleep efficiency and total sleep time and an increase in wake after sleep onset noted in the OSA group (83.90 vs 89.40, P = .003; 368.50 vs 387.25, P = .001; 40.1 ± 35.59 vs 28.66 ± 24.14, P = .007; 29.00 vs 20.50; P = .011). No significant difference was found in N3 sleep stage (33.60 vs 30.60, P = .14). CONCLUSION: We found evidence that children with OSA have a disturbance in their sleep architecture. The changes indicate greater sleep fragmentation and more time spent in lighter stages of sleep. Future research is needed and should focus on more effective methods to measure alterations in sleep architecture.

Salvage of Infected Alloplastic Ear Reconstructions via Negative Pressure Wound Therapy.

This is the first description of Negative Pressure Wound Therapy (NPWT) use in rescuing alloplastic ear reconstructions. Previously considered a sign of certain impending failure, severe infections with frank purulence can be salvaged. As a more recently developed technique, porous polyethylene (PPE) ear reconstruction provides benefits when compared to rib techniques. Increasing surgeon awareness of complication management may lead to further adoption of the technique and improve reconstructive results. Described herein are two cases of draining infections following PPE ear reconstruction that were salvaged with satisfactory results. Laryngoscope, 2024.

Dual Option Microtia Clinic: A Comparison of Outcomes in Microtia Reconstruction Using Autologous Rib or Porous Polyethylene Implant.

Introduction: Auricular reconstruction techniques most frequently utilize either autologous costal cartilage or alloplastic porous polyethylene (PPE) implant. Objectives: To compare the aesthetic outcomes, number of surgeries, and complications in children who underwent microtia reconstruction with either rib or PPE implant by blinded photograph review. Methods: This retrospective cohort study included consecutive pediatric patients who underwent auricular reconstruction with either autologous cartilage or PPE between November 2017 and February 2022. Blinded observers rated each postoperative ear through a web-based survey. Data on patient characteristics, operative time, length of admission, and complications were collected, bivariate analyses were performed using chi-square or Fisher's exact tests for categorical variables and Wilcoxon rank-sum test for continuous variables. Results: Forty-four ears were included, 28 of which (63.6%) were reconstructed with cartilage. Median patient age was 8 years (range 4-18 years) and 29 (65.9%) were male. The cartilage group had more surgeries (median 2.5 vs. 1.0, p < 0.001), and total operating time across all surgeries did not differ significantly. Conclusion: The two groups in our study had similar rates of complications and aesthetic scores, and aesthetic scores were worse for ears with wound complications requiring unplanned revisions.

Pediatric Invasive Fungal Rhinosinusitis: A Comprehensive Analysis of Prognostic Factors for Survival.

OBJECTIVE: Pediatric invasive fungal rhinosinusitis (IFS) is a devastating infection that manifests almost exclusively in immunocompromised children. The goal of this work was to determine which clinical features carry prognostic value for survival. METHODS: A retrospective review of children with a histopathological diagnosis of IFS was performed at an academic tertiary care institution from 1990 to 2021. Clinical variables were collected to generate survival and life-table estimators at 6-months and 1-year. RESULTS: Eighteen patients were included in this analysis, with a mean age of 9.8 years (range, 1-17 years). Most children were neutropenic (n = 15, 83.3%), with acute lymphoblastic leukemia (n = 10, 55.6%) representing the most common primary diagnosis. A mean of 3.2 operations (range 1-7 operations) was performed per patient for either mucormycosis (n = 10, 55.6%) or aspergillosis (n = 8, 44.4%). The mean time to absolute neutrophil count recovery was 65.8 days (range 20-137 days), with a 6-month and 1-year survival rate of 47.6% and 41.7%, respectively. Gross total resection (p = 0.006, p < 0.001), number of antifungals (p = 0.0004, p = 0.0003), and total operation number (p = 0.0032, p = 0.0035), served as positive prognostic factors for 6-month and 1-year survival. Conversely, altered mental status (p = 0.0026), cerebral involvement (p = 0.0010), cranial neuropathies (p < 0.0001), hyperglycemia (p = 0.0445, p = 0.0208), and intensive care unit status (p = 0.0013) served as negative prognostic factors for 6-month and 1-year survival. CONCLUSION: Several key elements were identified and found to play a vital role in influencing survival for pediatric IFS. Early diagnosis, prompt medical therapy, and aggressive surgical intervention remain at the forefront in the treatment of this complex opportunistic infection.

Identifying Posterior Fossa Abnormality in Pediatric Aerodigestive Patients, a Case Series.

OBJECTIVES: Multidisciplinary clinics like Aerodigestive programs focus on issues associated with airway, pulmonary, and gastrointestinal issues. Rarely, significant neurological issues like posterior fossa abnormality are identified as the primary etiology. We describe 3 such patients and compare their clinical presentation to the other patients seen in Aerodigestive clinic. METHODS: A retrospective chart review was conducted to review the 3 posterior fossa patients and the remainder of children that were referred to the Aerodigestive Clinic at Children's Hospital Los Angeles from June 2016 to August 2018. Clinical characteristics including triple endoscopies and sleep studies were recorded. RESULTS: Of the 110 patients included for review, 3 patients (3%) had an underlying posterior fossa abnormality; all of whom had symptoms of sleep disordered breathing along with dysphagia compared with 30% incidence of this symptom profile in the remaining Aerodigestive population. CONCLUSION: Presence of sleep disordered breathing and dysphagia, with underlying vomiting history, warrants considering evaluation for posterior fossa abnormalities in addition to traditional workup for aerodigestive disorders. Due to the rarity of this presentation and small sample size, future studies with multicenter collaboration may help better describe identifiers to delineate this population with similar aerodigestive symptoms and clarify diagnostic algorithms.

Malignancy Rates by Bethesda Subcategory in the Pediatric Population.

INTRODUCTION: While the Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) is the most widely used method for categorizing thyroid nodules, its applicability to children is often debated. We describe our institution's experience utilizing the TBSRTC and examine the rates of malignancy in our population. METHODS: We conducted a retrospective chart review of eligible patients undergoing primary thyroidectomy at a high-volume tertiary care pediatric hospital. All patients had pre-operative fine needle aspiration. RESULTS: Of the 112 patients in our cohort, 85 (76%) were female. The median age was 15.1 years. The patients were divided into groups based on the Bethesda categorization of the fine needle aspirations of their nodules. The percentages of patients whose resection specimens showed evidence of malignancy on the surgical pathology reports were recorded as follows: category I (n = 5): 20%, category II (n = 11): 0%, category III (n = 30): 17%, category IV (n = 13): 31%, category V (n = 17): 94% and category VI (n = 36): 100%. CONCLUSION: Our findings indicate that the malignancy rates at our institution are comparable to those reported by other high-volume studies. When compared with the 2017 TBSRTC data, we found that our results were similar in many categories, with the exception of categories I and V.

Incidence of thymic tissue in pediatric thyroidectomy.

OBJECTIVES: The nuances in the technical approach to pediatric thyroidectomy have been sparsely reported in the literature. No previous studies have reported on the rates of unintentional thymic tissue excision during pediatric thyroidectomy. In this study, we sought to describe the rates of thymic tissue excision noted on surgical specimens from pediatric thyroidectomies and investigate any correlations with preoperative factors and long-term outcomes. METHODS: A retrospective chart review was conducted of patients who underwent thyroidectomy at a tertiary care children's hospital between January 2010 and October 2020. Presence of thymic tissue (PTT) was defined as any pathologist-documented evidence of thymic tissue in the surgical specimen. Patient characteristics, operative details, and disease related datapoints were investigated for any correlation with PTT. RESULTS: Of the 209 patients who underwent thyroidectomy in the study period, 53 (25%) had PTT. After conducting a stepwise multivariate analysis, those with a concomitant central neck dissection had 3.3 times the odds of having PTT as compared to those with no neck dissection (p = 0.013, 95%CI: 1.3, 8.3). Additionally, patients with evidence of incidental parathyroidectomy had 8.99 times the odds of also having PTT as compared to those without IPE (p < 0.001, 95%CI: 4.0, 20.1). CONCLUSION: This is the first report analyzing the rate of thymic tissue excision during pediatric thyroidectomy. Thyroid surgeons should be prepared to encounter thymic tissue during pediatric cases and be aware of its associated risk of incidental parathyroid gland excision and dissection of tissue beyond intended surgical limits.

Thyroid tumor ratio: Improving the assessment of the impact of size in pediatric thyroid cancer.

BACKGROUND: The impact of thyroid nodule size is less useful in children who have smaller thyroid volumes than in adults. We investigate using a novel thyroid tumor ratio measurement in children with thyroid cancer. METHODS: Patient and pathologic characteristics were investigated via Student's t-test in a univariate analysis for any correlation with the log-transformed tumor ratio, followed by a multivariate linear regression. RESULTS: Of 75 patients with malignancy and tumor ratio information, mean ratio decreased with increasing age (p = 0.04). Out of several clinical factors, patients with lymph node metastases and those treated with postoperative radioactive iodine had significantly higher mean tumor ratios on multivariate analysis (p = 0.04 for both factors). CONCLUSIONS: Our study is the first to describe thyroid tumor volume in pediatric thyroid cancer and shows that increased tumor ratio was associated with indicators of more advanced disease such as lymph node metastases and use of radioactive iodine.

Postoperative respiratory adverse events in children after endoscopic laryngeal cleft repair.

PURPOSE: Due to the serious nature of respiratory adverse events, understanding their incidence can help in decisions regarding safe postoperative disposition. There have been no studies, however, evaluating the risk of postoperative respiratory adverse events (PRAEs) in children undergoing endoscopic laryngeal cleft (LC) repair, which is the primary objective of this study. METHODS: We conducted a retrospective chart review of all patients who underwent LC repair at a large tertiary children's hospital from 2015 to 2020. PRAEs were defined as having at least one of the following: remained intubated, required reintubation, required positive pressure ventilation, required high flow O2 nasal cannula, or required more than one dose of racemic epinephrine. Univariate analyses compared demographic, preoperative characteristics, and intraoperative characteristics between those with and without a PRAE. RESULTS: Overall, 8/26 (31%) patients had a PRAE and there were no differences between patients who did and did not have a PRAE and most comorbidities. Younger age (p = 0.03), being male (p = 0.07), and being admitted preoperatively (p = 0.07) were potentially associated with PRAEs. Need for intraoperative intubation for any reason or duration was associated with increased incidence of PRAEs (p = 0.02). CONCLUSION: The overall 31% incidence of postoperative respiratory adverse events reaffirms the appropriateness of PICU disposition for a large proportion of children undergoing endoscopic LC repair. Further studies with increased sample sizes are needed to tease apart patient or procedure-specific factors that significantly increase the risk of respiratory adverse events to have more definitive evidence regarding safe postoperative disposition.

Preoperative SARS-CoV-2 Screening Fails to Detect Viral Particles Prior to Airway Surgery.

OBJECTIVES/HYPOTHESIS: Children have higher rates of asymptomatic SARS-CoV-2 infections or milder courses of infection, and their carrier status may potentially impact viral transmission to those providing them care. The aim of this study is to compare the existing COVID-19 preoperative screening protocols to the detection of SARS-CoV-2 viral particles in surgical samples. STUDY DESIGN: Cross-sectional study. METHODS: We conducted a prospective study with consecutive convenience sampling of children undergoing adenoidectomy between January and April 2021. Total nucleic acid was extracted from adenoid tissue and real-time reverse transcription-polymerase chain reaction was conducted to test for the presence of SARS-CoV-2 viral particles. Univariate logistic regression was used to summarize the effect size of variables of interest on the odds of having SARS-CoV-2 positive adenoid tissue. RESULTS: Forty adenoid samples were collected and 11 (27.5%) had a positive SARS-CoV-2 reverse transcriptase-polymerase chain reaction. Patients with positive adenoids were older (11.8 vs. 7.9 years, odds ratio: 1.3, P = .01) and more likely to have had a positive nasopharyngeal swab in the previous 90 days (4/11 or 36% vs. 0). CONCLUSION: These data are the first report on the presence of SARS-CoV-2 particles in pediatric adenoidectomy specimens, with a high percentage of patients showing evidence of viral particles within the adenoid. This finding calls in to question the utility of preoperative COVID screening protocols which have yet to be rigorously validated in asymptomatic patients and have the potential to delay patients' surgical care.

Microtia Reconstruction and Erector Spinae Block in Children: A Case Series With Chart Review.

OBJECTIVES: Autologous reconstruction of microtia is advantageous due to its inherent biocompatibility and long-term stability, but postoperative pain associated with costal harvest is a significant issue. A well-planned pain management approach is imperative. Our objective is to introduce the novel application of erector spinae block anesthesia in pediatric microtia reconstruction and evaluate its impact on pain scores, use of opioids, and hospital length of stay. STUDY DESIGN: Case series with chart review. SETTING: Patients undergoing stage 1 microtia reconstruction at a tertiary pediatric hospital. METHODS: Data collected included demographics, opioid amounts, Wong-Baker FACES Pain Rating Scale scores, opioid-related side effects, and hospital length of stay. We used generalized estimating equations to examine the effect of erector spinae block use on total opioid use and pain scores and a linear regression model to assess the effect on hospital stay. RESULTS: Forty-seven patients were included: 14 in the erector spinae block group and 33 in the continuous wound pump group. The mean age was 8.3 years (SD, 2; range, 6-13), and 13 (32%) were female. Patients in the erector spinae block group had a 65.44% decrease in adjusted total opioid use (95% CI, -79.72% to -41.10%; P < .0001), a decrease in length of hospital stay (ß = -1.69 [95% CI, -2.11 to -1.26], P < .0001), and no difference in reported pain scores when compared with patients in the continuous wound pump group. CONCLUSIONS: This study demonstrates that early experience with an erector spinae block resulted in decreased opioid use and shorter hospital stay as compared with continuous wound infiltration with local anesthetic.

Disparities in Access to Pediatric Otolaryngology Care During the COVID-19 Pandemic.

OBJECTIVE: Racial/ethnic minority pediatric otolaryngology patients experience health disparities, including barriers to accessing health care. Our hypothesis for this study is that Hispanic or economically disadvantaged patients would represent a larger percentage of missed appointments and report more barriers to receiving care during the COVID-19 pandemic. METHODS: A cross-sectional survey utilizing a modified version of the Barriers to Care Questionnaire was administered via telephone to no-show patients, and median income by zip code was collected. Chi-squared, logistic regression, and Student's t-tests were used to investigate any differences in those who did and did not keep their appointments as well as any differences in mean questionnaire scores. RESULTS: No-show patients were more likely to be Hispanic than not (OR 2.3, 95% CI: 1.3, 3.9, P = .002) and to live in a zip code that had a median income less than 200% of the federal poverty level (OR 1.7, 95% CI: 1.2, 2.4, P = .004). Respondents with a high school degree tended to report more barriers to care compared to those with less education. CONCLUSION: In our study, we identified ethnic, financial, and logistic concerns that may contribute to patients failing to keep their appointments with the otolaryngology clinic. Future studies are needed to assess the efficacy of measures aimed to reduce these barriers to care such as preventive plans to assist new patients and expanding telehealth services.

Rate of Incidental Parathyroidectomy in a Pediatric Population.

OBJECTIVE: Incidental parathyroidectomy is a relatively common occurrence in thyroid surgery, which may lead to hypoparathyroidism and postoperative hypocalcemia, but it is not well studied in children. The objectives of this study were to determine the rate of incidental parathyroidectomy, identify potential risk factors, and investigate postoperative complications in children undergoing thyroidectomy. STUDY DESIGN: Retrospective cohort study. SETTING: Patients who underwent thyroidectomy over a 10-year period at a tertiary children's hospital. METHODS: Pathology reports were reviewed to determine incidental parathyroid gland tissue. Additional data collected included patient demographics, type of procedure, underlying thyroid pathology, as well as immediate and long-term postoperative clinical outcomes. RESULTS: Of 209 patients, 65 (31%) had incidental parathyroidectomy. Several variables were associated with incidental parathyroidectomy on univariable analysis. However, in the final multivariable model, only thyroidectomy with lymph node dissection was associated with increased odds of having incidental parathyroidectomy (odds ratio, 3.3; P = .04; 95% CI, 1.1-9.8). After a median follow up of 1 year, a significantly higher percentage of patients with incidental parathyroidectomy had evidence of long-term hypoparathyroidism (9/62 [15%] vs 3/144 [2%], P = .001). CONCLUSION: Incidental parathyroidectomy was relatively common in our pediatric thyroidectomy population, which may be a result of several anatomic, clinical, and surgeon-related factors. Close attention to parathyroid preservation with meticulous surgical technique is the most practical method of preventing long-term hypoparathyroidism and hypocalcemia.

Perioperative respiratory adverse events in children undergoing triple endoscopy.

OBJECTIVES: Children with aerodigestive disorders often have many of the reported risk factors for development of perioperative respiratory adverse events. This study sought to evaluate the incidence of such events in this group of patients undergoing general anesthesia for "triple endoscopy" (flexible bronchoscopy with bronchoalveolar lavage, rigid laryngoscopy and bronchoscopy, and esophagogastroduodenoscopy) and to identify any patient-specific or procedure-specific risk factors associated with higher incidence of perioperative respiratory adverse events. METHODS: We performed a retrospective chart review of children 18 years or younger who underwent triple endoscopy as part of an aerodigestive evaluation. Data collected from medical records included: preoperative polysomnography, symptoms of acute respiratory illness, medical comorbidities, demographics, postoperative hospital or intensive care unit admission, and all respiratory events and interventions in the perioperative period. Patient-specific and procedure-specific factors were investigated via univariate analysis for any correlations with perioperative respiratory adverse events. RESULTS: Of the 122 patients undergoing triple endoscopy, 69 (57%) experienced a perioperative respiratory adverse event. We found no difference in the incidence of perioperative respiratory adverse events among children with documented lung disease compared with those with no lung disease (OR: 0.89, p = .8 95% CI: 0.43, 1.8), and no significant difference between those children who had a respiratory illness at the time of surgery, 1-2 weeks prior, 3-4 weeks prior, and those with no preceding respiratory illness. A higher percentage of males had a perioperative respiratory adverse event, compared with females (OR: 2.7, p = .01 95% CI: 1.3, 5.09). CONCLUSION: Patients undergoing triple endoscopy for evaluation of aerodigestive disorders at our institution experienced perioperative respiratory adverse events at a rate of 57%.

Risk factors for peri-operative respiratory adverse events after supraglottoplasty.

OBJECTIVE: To determine demographic and peri-operative characteristics that predict peri-operative respiratory adverse events (PRAE) requiring intensive care unit (ICU) level intervention after supraglottoplasty. STUDY DESIGN: Case series with chart review. SETTING: Tertiary care children's hospital. METHODS: Retrospective chart review was conducted of children with laryngomalacia who underwent supraglottoplasty between October 2014 and November 2019. PRAE were defined as any of the following events or requirements within 24 h of surgery: 1) failure to extubate, 2) reintubation, 3) positive pressure ventilation, 4) more than one dose of racemic epinephrine, or 5) greater than 4 L of oxygen via nasal cannula. RESULTS: Fifty-one subjects were enrolled, with a median age of 4.8 months and majority (62 %) Hispanic. Twenty-one (41 %) subjects experienced PRAE. After adjusting for age and gender on multivariate analysis, children admitted preoperatively to the ICU were more likely to have PRAE than those not admitted or admitted to a floor unit (OR 40.1, 95%CI: 4.1-388.6, p = 0.001). Additionally, children with intraoperative oxygen desaturations below 90 % for greater than 1 min were more likely to have PRAE than those who did not (OR 21.3, 95%CI: 2.4-189.9, p = 0.006). Other factors significantly associated with PRAE on univariate analysis included chronic lung disease, congenital cardiac abnormality, history of intubation, supplemental oxygen requirement, gastrostomy tube dependence, intraoperative intubation and longer surgery length. CONCLUSION: Preoperative ICU admission and intraoperative oxygen desaturations are independent risk factors for PRAE after supraglottoplasty. Results from this study can help inform decisions regarding the appropriate level of postoperative care required after supraglottoplasty. LEVEL OF EVIDENCE: IV.

Exceptionally early tympanostomy tube placement in pediatric patients with cleft lip and palate.

OBJECTIVE: At our institution, cleft lip repair is performed at or before 8 weeks of age, and tympanostomy tubes (TT) have been inserted concurrently in some of these patients. Our objective was to determine the feasibility and present the preliminary results of TT placement at this early age. METHODS: A retrospective review was conducted of 22 patients born with cleft lip and/or palate who had TT placement in the first 8 weeks of life. Data collected included complications and audiologic function post TT placement. RESULTS: Subjects had a mean age of 3.9 weeks at the time of TT placement and cleft lip repair. Thirteen patients (59%) reported otorrhea during the follow-up period. Eighteen of 21 (86%) patients who underwent auditory evaluation had normal audiological function following TT placement. One patient had sensorineural hearing loss and 2 patients had mild conductive hearing loss due to bilateral extruded TT and OME at 15.9 and 39.2 months after surgery. CONCLUSION: Exceptionally early TT is feasible. Placing TT at or before 8 weeks of age did not result in any major complications but demonstrated a high incidence of otorrhea. A randomized, prospective study with a larger sample size is necessary to determine the benefits of TT placement at this age.

Sleep positions in children with Down syndrome and obstructive sleep apnea.

OBJECTIVES: To assess sleep positions in children with both Down syndrome (DS) and obstructive sleep apnea (OSA) and determine if there is a preferred sleep position by severity of apnea. METHODS: A single-center retrospective review of patients with both DS and OSA was performed. Caregivers reported sleep position utilized greater than 50% of observed sleep time. Accuracy of this report was confirmed through review of hypnograms from polysomnography studies. RESULTS: Eighty-two patients met inclusion criteria. Median body mass index (BMI) was 26.6 and 56% of patients had a prior tonsillectomy and/or adenoidectomy. The mean obstructive AHI (OAHI) was 25.33 with 90.4% having severe OSA, 9.6% having moderate OSA, and no patients having mild OSA. Reported sleep positions were skewed towards lateral/decubitus (82.9%) compared to prone (11.0%) and supine (6.1%). This was consistent with hypnogram data where 71% of total sleep time in lateral/decubitus positions compared to prone (13%) and supine (6%). The median changes in sleep position per patient was 5 (IQR: 3-6). Lower BMI (p < 0.001, 95% CI: 0.32-1.13) and tonsillectomy (p < 0.001, 95% CI: 7.7-18.19) were associated with lower OAHI. Sleep position was not associated with age (p = 0.19), sex (p = 0.66), race (p = 0.10), ethnicity (p = 0.68) nor history of tonsillectomy (p = 0.34). Preferred sleep position was not correlated with OAHI (p = 0.78, r = 0.03) or OSA severity (p = 0.72, r = 0.03). CONCLUSIONS: This study highlights the possibility that children with DS may have preferential sleep positions that cater to optimized airflow in the context of OSA although further prospective study is needed.

The Relevance of and Surgical Approach to the Suprahyoid Region in Thyroglossal Duct Surgery.

OBJECTIVES: Persistent or recurrent disease following excision of a thyroglossal duct cyst/sinus (TGDC) is often found in the suprahyoid region. Cadaver dissections were performed to identify and name important surgical landmarks in the suprahyoid area; a histopathologic analysis of surgical specimens was completed to determine the incidence and extent of microscopic disease; and clinical outcomes were compared to determine the efficacy of a specific anatomic dissection. STUDY DESIGN: Retrospective case series. METHODS: Standardized dissections of four adult cadavers were performed. Consecutive surgical specimens were examined for evidence of microscopic TDGC disease in the suprahyoid region, measuring the greatest width and length of disease. A retrospective review of all consecutive TGDC procedures was completed. RESULTS: The important surgical landmarks in the suprahyoid area were identified in all cadavers. Microscopic disease in the suprahyoid area was found in 79% (37 of 47) of surgical specimens. The mean greatest length and width of microscopic disease was 12.4 mm and 1.4 mm, respectively. Following identification of these landmarks, the incidence of recurrent or persistent disease decreased (P = .02) from 5% (8 of 159) to 0% (0 of 112). CONCLUSION: The majority of pediatric patients with a TGDC will have microscopic disease in the suprahyoid area. The surgical landmark of the fascial plane between the geniohyoid and genioglossus muscles demarcates the anterior and lateral borders of resection in the suprahyoid area. This approach can be used as a reliable and easily reproducible technique in TGDC surgery to increase confidence of achieving complete removal of disease in the suprahyoid area, avoiding persistent or recurrent disease and a revision procedure.

Prospective Evaluation of a Smartphone Otoscope for Home Tympanostomy Tube Surveillance: A Pilot Study.

OBJECTIVES: Recent technological advances have led to the capability of performing high resolution imaging of the tympanic membrane. Smartphone technologies and applications have provided the opportunity to capture digital images and easily share them. The smartphone otoscope device was developed as a simple system that can convert a smartphone into a digital otoscope. This device has the prospective ability to improve physician-patient communication and assist with the diagnosis and management of ear disease. Our objective was to evaluate the feasibility and physician/parental satisfaction using the Cellscope® smartphone attachment for at home tympanostomy tube monitoring. METHODS: Children between 6 months and 15 years of age at an urban tertiary children's hospital that were scheduled for bilateral tympanostomy tube insertion or underwent bilateral tympanostomy tube surgery were prospectively enrolled in the study. Comparisons were made between parental home-recorded videos and findings during in-office otoscopy. Two independent otolaryngologists reviewed the videos and concordance between inter-rater agreements was calculated. Acceptability and use questionnaires were administered to physicians and parents. RESULTS: There was good intra-rater agreement between traditional otoscopy and video-otoscopy for tube extruding, tube blocked and tube extruded with at least 80% agreement (P < .05) and excellent inter-rater agreement between physicians for nearly all tube variables (P < .0001) There was a high degree of satisfaction with this mode of surveillance. Parents and physicians agreed that the CellScope® smartphone was easy to use, helpful with the occurrence of acute events, and appeared to improve quality of care. CONCLUSIONS: The CellScope® smartphone is feasible for use in tympanostomy tube surveillance. Use of the device may allow otolaryngologists to easily follow a child's tympanostomy tube remotely over time and offer greater parental satisfaction.
