Abstract
To examine the social perception of microtia and quantify the effect of reconstruction on socially perceived attributes.Parental consent was obtained for peri-reconstruction photographs in a patient with unilateral grade 3 microtia without an underlying craniofacial syndrome. With computer simulation, the normal, preoperative microtia, and postoperative reconstruction ear were isolated and blended into the oblique and lateral views of that volunteer's face to isolate ear morphology as a variable against a constant facial baseline. These photographs were embedded into Web-based surveys with visual analogue scales to capture social perception data and then were sourced to general population adults.Survey respondents totaled 631. On average, the face with the microtia ear was perceived to be less friendly (P = .015), less healthy (P = .022), and less successful (P = .005) than the same face with the "normal" ear. There were no statistically significant differences in socially perceived attributes between the face with the normal ear and the face with the reconstructed ear.This is the first study to examine the social perception consequences of microtia and microtia reconstruction in children. These findings may explain the significant psychosocial distress experienced by these patients by exploring the social perception of specific attributes perceived. Lastly, this study may better inform microtia patients and their physicians on the impact of auricular reconstruction on third party's perception of social attributes.N/A Laryngoscope, 2020.

Abstract
Importance: Current therapeutic options for patients with extracranial head and neck arteriovenous malformations are limited. Surgical intervention, such as sclerotherapy or resection, often result in rapid recurrence and progression of disease.Objective: To assess the efficacy and tolerability of sirolimus as an adjuvant therapy for endovascular embolization in the management of complicated extracranial head and neck arteriovenous malformations.Design, Setting, and Participants: This case series examined 6 patients with extracranial head and neck arteriovenous malformations treated from January 1, 2013, to December 31, 2017, at a multidisciplinary vascular anomalies clinic within Stanford Hospital and Clinics.Intervention: Initiation of sirolimus at least 1 month prior to endovascular embolization, targeting a trough level of 10 to 15 ng/mL throughout the course of the endovascular embolization series and continued for at least 1 month after the series.Main Outcomes and Measures: Clinical manifestations; disease progression and overall response to treatment were assessed via clinical evaluation and radiographic imaging.Results: All 6 patients (4 male and 2 female patients; mean age, 24.5 years [range, 9-44 years]) responded favorably to the combination of sirolimus therapy followed by endovascular embolization, and 4 patients exhibited a near-complete response. The median duration of follow-up was 19 months (range, 6-40 months). One patient discontinued sirolimus soon after embolization and experienced regrowth of the arteriovenous malformation after 1 year. Sirolimus was resumed, which has stabilized his disease for more than 2 years. Mild adverse effects were noted in 4 patients. The combination therapy was well tolerated in all patients. One patient developed skin ulceration after embolization and required surgical debridement. Another patient developed pulmonary microthrombi after embolization with cyanoacrylate glue that resolved with a brief course of anti-inflammatory therapy.Conclusions and Relevance: Although further prospective trials are needed, this report suggests the benefit of a mammalian target of rapamycin inhibitor as an adjuvant therapy for surgical embolization of complex, extracranial head and neck arteriovenous malformations. The optimal dosing and therapeutic duration of sirolimus treatment before and after embolization remain to be determined.

Abstract
OBJECTIVE: Renal abnormalities are commonly considered in the work up of pediatric patients with external ear malformations. However, there is little consensus regarding an appropriate renal screening protocol for patients with microtia. We sought to characterize renal abnormalities detected on ultrasonography in pediatric patients with microtia.METHODS: We conducted a retrospective cohort study of pediatric patients diagnosed with microtia who underwent renal ultrasound from 1991 to 2014 at a single tertiary academic institution. Renal ultrasound reports and medical records were reviewed to assess for renal abnormalities and to determine whether patients required specialist follow-up or interventions. Audiograms and otolaryngology notes were used to determine patterns of hearing loss. The following additional information was recorded from the electronic medical records: patient sex, microtia grade (I-IV), microtia laterality, and known associated syndromes. Characteristics were compared between those who did and did not have renal ultrasound findings using Fisher's exact test. Univariate logistic regression analysis was performed to determine factors associated with renal ultrasound findings.RESULTS: The majority of patients in this cohort were syndromic (n = 51, 64%) with grade III microtia (n = 46, 58%) and conductive hearing loss (n = 58, 72%). Syndromic children with microtia demonstrated a higher crude rate of renal ultrasound abnormalities (22%) than children with isolated microtia (7%). Of these patients, 69% required specialist follow-up. Univariate logistic regression analysis did not identify predictors that were significantly associated with renal ultrasound findings.CONCLUSION: Fairly high rates of abnormalities in syndromic and non-syndromic patients may warrant screening renal ultrasound in all patients with microtia, especially given the high percentage of findings requiring renal follow-up. A prospective study to formally evaluate screening efficacy is needed.

Abstract
Introduction and Objectives: There has been an emergence of procedures to release the superior labial frenula in infants, yet little is known about the normal appearance or incidence of severe attachment, or "lip-tie." The objective of this article was to develop a classification system for superior labial frenula and to estimate the incidence of different degrees of attachment. Methods: A prospective cross-sectional study. Newborns were examined and had photographs taken of their upper frenula. Relevant medical professionals rated the appearance of the labial frenula using a previously described Kotlow classification system. The raters assessed each photograph twice and were blinded to their previous rating and to other raters' scores. Results: All newborns have a labial frenula, with most attached at the gingival margins (83%). Raters had poor intra- and interrater reliability (64% to 74% and 8%, respectively), using the Kotlow classification system, which improved when the classification system was simplified. Conclusions: The Kotlow classification of lip-tie fails to be reproducible by relevant experts. The majority of infants had a significant level of attachment of the labial frenulum. As more procedures are done to release the upper lip frenulum, it is important to understand what degree of attachment is normal, or more common.

Abstract
Silent sinus syndrome is characterized by an asymptomatic hypoplastic maxillary sinus with progressive enophthalmos and hypoglobus. This is a disease rarely affecting children with the majority of reported cases involving adult patients. Treatment is primarily surgical with endoscopic sinus surgery to restore aeration of the sinus along with orbital reconstruction to restore facial symmetry. In this report, we describe a 7 year old child with facial asymmetry and no sinonasal symptoms. CT showed an opacified hypoplastic right maxillary sinus. One year after endoscopic sinus surgery, there was spontaneous improvement of facial asymmetry and relative maxillary sinus size.

Abstract
Propranolol has recently emerged as an effective therapy for infantile hemangiomas causing regression. The β-adrenergic receptor (AR) antagonist is thought to cause vasoconstriction by its effect on nitric oxide, block angiogenesis by its effect on vascular endothelial growth factor (VEGF), and induce apoptosis. In a prior report, we identified expression of β2-AR (B2-AR) and its phosphorylated form (B2-ARP) in a case of infantile hemangioma that responded to propranolol treatment. We now explore the expression of βARs on a variety of vascular lesions utilizing a tissue microarray containing 141 lesions, including infantile hemangiomas, angiosarcomas, hemangiomas, hemangioendotheliomas, and various vascular malformations. The array was immunostained for B2-AR, B2-ARP, and β3-AR (B3-AR), and the results scored for the intensity of endothelial cell expression as negative, weak positive, or strong positive. All phases of infantile hemangiomas had strong expression of all three receptors, with the exception of only weak expression of B2-ARP in the proliferative phase infantile hemangioma. Strong expression of all three receptors was present in many hemangiomas, hemangioendotheliomas, and vascular malformations. Absent to weak expression of all three receptors was seen in glomus tumor, hobnail hemangioendothelioma, pyogenic granuloma, and reactive vascular proliferations. This is the first study to report β-AR expression in a variety of vascular lesions. Although immunohistochemical expression of the receptors does not necessarily indicate that similar pathways of responsiveness to β-blockade are present, it does raises the possibility that β-blockade could potentially affect apoptosis and decrease responsiveness to VEGF. Additional study is warranted, as therapeutic options are limited for some patients with these lesions.

Abstract
Ten to twenty percent of children have persistent obstructive sleep apnea (OSA) after adenotonsillectomy (T&A). We hypothesize that sleep endoscopy, a flexible fiberoptic examination of the pharynx under anesthesia, is an effective tool for identifying sites of persistent obstruction.In this retrospective cohort study, we reviewed records of children who had symptoms consistent with OSA and a positive polysomnogram (PSG) who underwent sleep endoscopy followed by sleep endoscopy directed surgery. Data collection included age, BMI and co-morbidities. Apnea-hypopnea index (AHI) was compared to pre and post surgery for each child using a paired t-test.Of the 80 children who underwent sleep endoscopy followed by directed surgery, 65% were male, mean age was 6 years (SD 3.75 years), average BMI was 19 (SD 0.43 years) and 28% had co-morbidities. For the 51% of patients who had persistent OSA after T&A, the mean AHI after sleep endoscopy directed surgery was significantly lower then before surgery (7.9 vs. 15.7, p<.01). For the 49% of patients who had never undergone surgery for OSA, or who were surgically naïve, and underwent sleep endoscopy directed surgery, the mean AHI was significantly lower then before surgery (8.0 vs. 13.8, p<.01).Sleep endoscopy is a consistently reliable tool for identifying the sites of obstruction in both surgically naive children and those with persistent OSA after T&A.

Abstract
To evaluate the polysomnographic outcomes after supraglottoplasty (SGP) performed for obstructive sleep apnea syndrome (OSAS) associated with occult laryngomalacia.Retrospective case series with medical chart review.Tertiary pediatric medical center.Twenty-two patients aged 2 to 17 years met the inclusion criteria of polysomnography-proven OSAS and occult laryngomalacia seen on flexible fiber-optic sleep endoscopy. Infants with congenital laryngomalacia were excluded.Carbon dioxide laser SGP was performed either alone or in conjunction with other operations for OSAS.Preoperative and postoperative nocturnal polysomnographic data were paired and analyzed statistically.Supraglottoplasty for occult laryngomalacia resulted in statistically significant reduction in the apnea-hypopnea index (AHI) (from 15.4 to 5.4) (P <.001). Subgroup analysis of children who underwent either SGP alone or in combination with other interventions showed comparable reductions in AHI. Medical comorbidities were associated with worsened postoperative outcomes, although still significantly improved compared with baseline. Overall, 91% of children had an improvement in AHI, and 64% had only mild or no residual OSAS after SGP.Supraglottoplasty is an effective technique for the treatment of OSAS associated with occult laryngomalacia.

Abstract
(1) To present six patients with symptomatic airway hemangiomas treated with oral propranolol. (2) To review the diagnostic and treatment options for airway hemangiomas and propose a new management protocol.Retrospective review.Tertiary care children's hospital.Pediatric patients diagnosed with obstructive airway hemangiomas treated with oral propranolol. Patients were followed for symptomatic improvement and relief of airway obstruction on imaging or laryngoscopy.Seven patients presenting with airway obstruction were treated with propranolol. One patient had a focal hemangioma confined to the subglottis. Four patients had airway hemangiomas that extended beyond the confines of the larynx and trachea. A sixth patient had a bulky supraglottic hemangioma. A seventh patient with an extensive maxillofacial lesion failed propranolol therapy and was found to have a pyogenic granuloma on final pathology after excision. Six patients had failed standard medical therapy and/or surgical interventions and were treated successfully with oral propranolol with improvements in airway symptoms and oral intake, requiring no further surgical intervention. Treatment was initiated as early as 1.5 months of age, and as late as 22 months. No adverse side effects of propranolol were noted.Oral propranolol was successfully used to treat airway hemangiomas, resulting in rapid airway stabilization, obviating the need for operative intervention, and reducing the duration of systemic corticosteroid therapy while causing no obvious adverse effects. These outstanding results enable the possibility of use of a standardized diagnostic and treatment algorithm for airway hemangiomas that incorporates systemic propranolol.

Abstract
To determine the rate of recovery of pediatric vocal fold paralysis (VFP) after cardiac surgery.Retrospective case series from January 2000 to 2005 at 4 tertiary care pediatric hospitals.A total of 109 children with VFP were identified. Of 80 patients with follow-up >3 months, 28 (35%) recovered vocal fold function with a median time to diagnosis of recovery of 6.6 months. Fifty-two (65%) patients had persistent vocal fold paralysis with a median follow-up time of 16.4 months. Twenty-five (45%) of 55 patients demonstrated aspiration or laryngeal penetration with modified barium swallow. Twenty-nine (27%) of the 109 patients underwent surgical intervention for their airway, feeding, or voice.Pediatric VFP is not an uncommon complication after cardiac surgery and can result in serious sequelae. This study demonstrates a 35% rate of recovery, 45% rate of aspiration, and 27% rate of complications that require surgical intervention.

Abstract
We present a pediatric case report of cisplatin-induced ototoxicity with subsequent recovery. The patient experienced tinnitus and fluctuating mild high-frequency sensorineural hearing loss (SNHL) with a concomitant decrease in distortion product otoacoustic emissions (DPOAE). There was recovery of hearing loss and return of DPOAE at 1 year after completion of cisplatin therapy. Reports of recovery from cisplatin-induced ototoxicity in humans are limited in the literature, especially in the pediatric population. A review of cisplatin ototoxicity and mechanisms of recovery are discussed, with an emphasis on the particular chemotherapy regimen and dosing schedule in this case, given at 4-11 week intervals.
