Pharyngeal wall and soft palate motion after two common speech surgeries.

PURPOSE: To assess how pharyngeal wall and soft palate motion are affected after two common interventions for velopharyngeal insufficiency. MATERIALS AND METHODS: A retrospective observational study was performed. A database of patients who had undergone Furlow palatoplasty or pharyngeal flap surgery between 2011 and 2019 and had video-archived preoperative and postoperative nasopharyngoscopy recordings was created. Recordings were deidentified and randomized, with 5 randomly-selected videos duplicated to determine intra-rater reliability. The videos were scored by 3 experienced raters using a modified Golding-Kushner scale. Pre- and postoperative scores were compared using paired t-test. Inter- and intra-rater reliability were estimated using intra-class correlation (ICC). RESULTS: There were 17 patients who met inclusion criteria. The mean age was 6.9 years (range 3-22 years, 59% male). In the Furlow palatoplasty group (n = 9), an increase in left soft palate motion was noted postoperatively (t(8) = 2.71, p = 0.02). In the pharyngeal flap group (n = 8), increases in lateral pharyngeal wall motion (left: t(7) = 3.58, p = 0.008, right: t(7) = 3.84, p = 0.006) and right soft palate motion (t(6) = 2.49, p = 0.04) were identified. Intra-rater reliability and inter-rater agreement were lower than prior studies utilizing the Golding Kushner scale. CONCLUSIONS: Our results provide objective evidence that Furlow palatoplasty and pharyngeal flap surgeries achieve velopharyngeal closure by increasing movement at different anatomical sites. Palatal and pharyngeal wall motion observed during preoperative nasopharyngoscopy may influence a surgeon's choice of intervention.

Ambient noise limits efficacy of smartphone-based screening for hearing loss in children at risk.

OBJECTIVE: To determine if hearScreen®, a smartphone-based pure tone audiometric screen, serves as an effective hearing screen for identifying hearing loss in children at risk, such as those with chronic otitis media and/or craniofacial anomalies. METHODS: A cross-sectional, single-center, prospective study at an urban tertiary care hospital was completed. From June to October 2019, a total of 208 pediatric ears at risk for hearing loss were evaluated by both hearScreen® and conventional pure tone audiometry. The efficacy of hearScreen® for detecting hearing loss in a pediatric population at risk was determined. RESULTS: A total of 208 pediatric ears at risk for hearing loss were screened. HearScreen® demonstrated a sensitivity of 85%, a specificity of 41%, a positive predictive value of 36%, and a negative predictive value of 87%. Subgroup analysis stratified by hearing loss type showed that hearScreen® screens for conductive hearing loss with increased sensitivity. CONCLUSIONS: This investigation suggests that hearScreen® may serve as a an accessible, low-cost, and sensitive pure tone audiometric screen for hearing loss in children at risk, particularly those with conductive hearing loss, with the caveat that it may generate a high proportion of false positives due to the influence of ambient noise, especially when screening at 500 Hz. Future investigations should weigh the utility of including 500 Hz in the screening protocol as well as assess methods that may mitigate the influence of ambient noise during a pure-tone audiometric screen.

Symptomatic Lingual Thyroglossal Duct Cyst in Children: A Laryngomalacia Phenotype.

OBJECTIVES: Patients with lingual thyroglossal duct cyst (TGDC) can present as symptomatic with obstructive airway and feeding difficulties. METHODS: We present 3 cases of symptomatic lingual TGDC. RESULTS: All 3 patients were diagnosed with laryngomalacia and underwent further concurrent or delayed airway intervention, in addition to cyst removal. CONCLUSIONS: We reason that there is a phenotype of laryngomalacia in the symptomatic lingual thyroglossal duct cyst patients who present with symptoms due to disruption in laryngeal anatomy rather than the cyst itself causing obstructive symptoms. Distinguishing this phenotype, especially in comparison to other pathologies such as vallecular cysts, may better allow for planning of concurrent or delayed airway procedures and overall counseling of parents.

Prophylactic Flexible Bronchoscopy Immediately following Open Airway Reconstruction in Children.

OBJECTIVES: Prophylactic flexible bronchoscopy immediately following open airway reconstruction allows for directed clearance of the distal airways, potentially reducing the rate of certain postoperative respiratory complications. In this investigation, we sought to determine if prophylactic flexible bronchoscopy at the conclusion of pediatric open airway reconstruction has any benefit over blind flexible suctioning of the trachea. METHODS: A retrospective, single-center study at an urban tertiary care hospital was completed. From January 2010 to April 2013, patients underwent open airway reconstruction, immediately followed by blind flexible suctioning of the trachea for distal airway clearance. From May 2013 through December 2016, sequential patients underwent prophylactic flexible bronchoscopy immediately following airway reconstruction. RESULTS: A total of 29 patients (age: 3.6 months-6.2 years) met inclusion criteria. Sixteen sequential patients underwent simple blind flexible suctioning and 13 sequential patients underwent directed, prophylactic flexible bronchoscopy. Demographics and comorbidities between the groups were equivalent other than slightly older age in the prophylactic bronchoscopy group. All clinical outcomes analyzed were equivalent other than faster time to room air (P < .002) and a decrease in the number of chest physical therapy sessions (P < .02) in a subset of patients who did not undergo prophylactic bronchoscopy. CONCLUSION: This investigation suggests that the use of prophylactic flexible bronchoscopy immediately following open airway reconstruction may not be superior to blind flexible suctioning of the trachea in limiting postoperative pulmonary complications. Further studies of greater power are needed to better elucidate any small differences that may exist between these two interventions.

Comparing the real and perceived cost of adenotonsillectomy using time-driven activity-based costing.

OBJECTIVE: This study aims to measure the costs of treating obstructive sleep apnea (OSA) in children with an adenotonsillectomy using time-driven activity-based costing (TDABC) and explore how this differs from cost estimates using traditional forms of hospital accounting. STUDY DESIGN: Prospective observational study. METHODS: A total of 53 pediatric patients with symptoms of OSA or sleep-related breathing disorder were followed from their initial appointment through surgery to their postoperative visit at an academic medical center. Personnel timing and overhead costs were calculated for TDABC analysis. RESULTS: Treating OSA with an adenotonsillectomy in a pediatric patient costs $1,192.61. On average, outpatient adenotonsillectomy costs $957.74 (80.31%); $412.18 of this cost ($4.89 per minute) was attributed to the overhead cost of the operating room. Traditional hospital accounting estimates outpatient adenotonsillectomy costs $2,987, with overhead attributing $11.27 per minute or $949.23 per case. 57% ($6.38 per minute) of the hospital's estimate for overhead was actually for equipment and implants used by different hospital services and not for equipment used in adenotonsillectomies. CONCLUSION: Through TDABC, we were able to highlight how traditional RVU-based hospital accounting systems apportion all overhead costs, including items such as orthopedic implants, evenly across specialties, thus increasing the perceived cost of equipment-light procedures such as adenotonsillectomies. We suspect that providers who perform a TDABC analysis at their home institution or practice will find their own unique insights, which will help them understand and control the different components of healthcare costs.

Cholesteatoma as a complication of Langerhans Cell Histiocytosis of the temporal bone: A nationwide cross-sectional analysis.

OBJECTIVE: To determine if patients with Langerhans Cell Histiocytosis (LCH) of the temporal bone have a higher risk of developing cholesteatoma. METHODS: Review of literature and cross-sectional weighted analysis of patients under 19 with a diagnosis of LCH from the National Inpatient Sample (NIS) and Kids' Inpatient Database (KID) from 2000 to 2013. ICD-9 codes and demographics were analyzed; pairwise comparisons and multivariate analyses were performed. RESULTS: Only seven cases of cholesteatoma after the treatment for LCH of the temporal bone have been documented in the literature. No significant association between cholesteatoma and LCH was seen (OR 0.747 [0.149-3.751]). Patients with LCH did have a higher incidence of chronic otitis media, chronic otitis externa, chronic sinusitis, hearing loss, and otitis media with effusion. CONCLUSION: Our results show that patients with Langerhans Cell Histiocytosis do not appear to have a higher risk of developing cholesteatoma. However they are more likely to be diagnosed with chronic otitis externa which should be differentiated from cholesteatoma or recurrence of LCH.

Palatal Motion After Primary and Secondary Furlow Palatoplasty.

Importance: Indications for Furlow palatoplasty include primary repair of cleft palate as well as secondary repair, or secondary palatoplasty for treatment of velopharyngeal insufficiency. Speculation exists surrounding the benefit of secondary Furlow palatoplasty in cases of a previously well-reconstructed palate or a short but otherwise anatomically normal soft palate because it has been theorized that reorientation of a previously reconstructed or normal muscular levator sling should in fact worsen palatal motion. Objective: To compare palatal motion following primary and secondary Furlow palatoplasty using footage from postoperative nasopharyngoscopy videos. Design, Setting, and Participants: In this retrospective case series, medical records in a database of an urban academic pediatric otolaryngology practice was used to identify patients who had undergone either primary or secondary Furlow palatoplasty. Subjects with adequate postoperative nasopharyngoscopy footage were randomized, and 2 blinded reviewers assessed soft palate motion in each video using an abbreviated version of the Golding-Kushner scale. Main Outcomes and Measures: Reviewers' blinded ratings of soft palate motion were quantified using a modified Golding-Kushner scale to generate a mean palatal motion score for each subject (range, 0.0-2.0). Scores of primary and secondary Furlow palatoplasty patients were compared. Results: Over a 4-year period, 20 patients with adequate postoperative nasopharyngoscopy footage were identified (12 primary Furlow palatoplasty patients and 8 secondary Furlow palatoplasty patients). Patients consisted of 8 males and 12 females and ranged in age from 12 months to 22 years at the time of postoperative nasopharyngoscopy. Modified Golding-Kushner scores were similar between groups: mean primary group, 1.61 (range, 0.5-2.0); mean secondary group, 1.53 (range, 0.75-2.0); absolute difference in mean, 0.08 (95% CI, 0.00-0.43); effect size, Hedges g, 0.18. There was fair interrater reliability (interclass coefficient, R = 0.45), consistent with prior reports using this scale. No significant difference in postoperative palatal motion scores was identified between primary and secondary palatoplasty groups in this study. Conclusions and Relevance: When examined in isolation, postoperative motion of the soft palate appears similar following both primary and secondary Furlow palatoplasty procedures, suggesting that there are no major deleterious effects on palatal motion following secondary Furlow palatoplasty.

A rare case of pediatric Nontraumatic Myositis Ossificans in the posterior triangle.

BACKGROUND: Myositis Ossificans Cicumscripta is a rare condition characterized by aberrant bone formation in paramuscular soft tissue of the extremities usually associated with trauma or a genetic mutation. Very few cases involve the head or neck and it is rarely found in the pediatric population. OBJECTIVES: We present a case of a 5-month old with a rapidly growing posterior neck mass suspicious for neoplasia, which was treated with surgical resection and found to be a non-traumatic, non-genetic form of Myositis Ossificans. The workup, treatment, and findings of the patient are outlined and a review of the literature on this disease is discussed. CONCLUSION: Myositis Ossificans is characterized by aberrant bone formation typically occurring after trauma but may be secondary to an underlying genetic abnormality. The case presented in the absence of trauma or an underlying genetic abnormality and is therefore an exceedingly rare instance of the sporadic form that presented spontaneously in the head and neck of a pediatric patient.

Endolymphatic duct violation during retrosigmoid dissection of the internal auditory canal: a human temporal bone radiographic study.

OBJECTIVE/HYPOTHESIS: Successful hearing preservation after acoustic neuroma resection is sometimes complicated by delayed hearing deterioration. The goal of this study was to investigate the hypothesis that internal auditory canal (IAC) drilling during retrosigmoid acoustic neuroma removal may result in endolymphatic duct (ELD) injury, a potential cause of delayed hearing loss (HL) after hearing preservation surgery. STUDY DESIGN: Temporal bone anatomic and radiographic study and literature review. METHODS: Twenty-one human temporal bones were analyzed with high-resolution multislice computed tomography (HRMCT) and subjected to standard retrosigmoid IAC dissection with labyrinthine preservation and follow-up HRMCT for analyses of the ELD. A MEDLINE search was performed of studies documenting long-term hearing preservation outcomes after retrosigmoid dissection. RESULTS: Five of 21 (24%) bones were found to have violation of the ELD despite preservation of labyrinthine structures and the endolymphatic sac. These results correlate with the mean incidence of long-term hearing decline (26.6%). Reviews of human and animal studies indicate that injury to the ELD may create endolymphatic hydrops. CONCLUSIONS: The ELD is vulnerable to injury during IAC dissection even if labyrinthine structures at the lateral aspect of the IAC are preserved. These findings may be helpful in explaining and potentially preventing some cases of long-term hearing deterioration that may be a result of endolymphatic hydrops after ELD injury during acoustic tumor removal. Careful preoperative review of imaging studies using HRMCT may prove useful before retrosigmoid dissection.

Otologic outcomes after blast injury: the Boston Marathon experience.

OBJECTIVE: Otologic trauma was the most common physical injury sustained after the April 15, 2013, Boston Marathon bombings. The goal of this study is to describe the resultant otologic morbidity and to report on early outcomes. STUDY DESIGN: Multi-institutional prospective cohort study. METHODS: Children and adults seen for otologic complaints related to the Boston Marathon bombings comprised the study population. Participants completed symptom assessments, quality-of-life questionnaires, and audiograms at initial and 6-month visits. Otologic evaluation and treatment, including tympanoplasty results, were reviewed. RESULTS: More than 100 patients from eight medical campuses have been evaluated for blast-related otologic injuries; 94 have enrolled. Only 7% had any otologic symptoms before the blasts. Ninety percent of hospitalized patients sustained tympanic membrane perforation. Proximity to blast (RR = 2.7, p < 0.01) and significant nonotologic injury (RR = 2.7, p < 0.01) were positive predictors of perforation. Spontaneous healing occurred in 38% of patients, and tympanoplasty success was 86%. After oral steroid therapy in eight patients, improvement in hearing at 2 and 4 kHz was seen, although changes did not reach statistical significance. Hearing loss, tinnitus, hyperacusis, and difficulty hearing in noise remain persistent and, in some cases, progressive complaints for patients. Otologic-specific quality of life was impaired in this population. CONCLUSION: Blast-related otologic injuries constitute a major source of ongoing morbidity after the Boston Marathon bombings. Continued follow-up and care of this patient population are warranted.

Lower island trapezius myocutaneous flap reconstruction of a large neck defect in an infant.

Free tissues transfer has been well-described in infants but there is limited data on techniques for reconstruction of large neck defects with regional myocutaneous flaps in this population. We report on the use of a lower island trapezius myocutaneous flap to reconstruct a large posterior neck and occiput wound in an 18-month-old child. The use of a regional myocutaneous flap allowed for reliable transfer of a relatively large volume of skin and soft tissue, providing coverage of the internal jugular vein and spinal accessory nerve as well as limiting the likelihood of debilitating scar contracture.

Photodynamic therapy of cottontail rabbit papillomavirus-induced papillomas in a severe combined immunodeficient mouse xenograft system.

OBJECTIVES/HYPOTHESIS: To evaluate the efficacy of photodynamic therapy (PDT) with the phthalocyanine photosensitizer Pc 4 for treating an animal model of recurrent respiratory papillomatosis (RRP). METHODS: Rabbit skin was grafted onto the dorsum of severe combined immunodeficient mice, two xenografts per animal. After the graft healed, it was inoculated with cottontail rabbit papillomavirus (CRPV). When papillomas developed, Pc 4 (0.6 or 1.0 mg/kg) was administered systemically, and 48 hours later, one papilloma of the two on each animal was exposed to 675-nm photoactivating light at either 100 or 150 J/cm(2). In addition to the contralateral tumors, which received Pc 4 but no light, other controls included animals receiving light only or neither agent. Response was assessed by measuring papilloma size with a caliper. Some papillomas and residual skin were harvested for histological assessment. RESULTS: For the lower-dose PDT regimens, papilloma growth rates were not significantly different from the controls. In contrast, 13 of 15 papillomas receiving the higher Pc 4 dose (1.0 mg/kg) and the higher light fluence (150 J/cm(2)) regressed completely and did not regrow within the observation period of up to 79 days. The response of these papillomas was significantly different from the controls (P < .001). Histological analysis confirmed the absence of residual tumor following complete response and replacement with near-normal epithelium. CONCLUSIONS: Pc 4-PDT is highly effective in treating virally induced (CRPV) papillomas in a murine model of RRP, and thus warrants further study as a treatment for HPV-induced papillomas.
