Objective:To describe the early surgical and audiometric outcomes in pediatric patients implanted with a new active transcutaneous bone conduction implant system.Study Design:Retrospective case review.Setting:Tertiary pediatric hospital.Patients:Pediatric patients (18 or younger) with conductive or mixed hearing loss that completed postoperative aided testing following implantation with the Cochlear Osia system from December 2019 to December 2020.Intervention:Rehabilitative.Main Outcome Measure:Preoperative air conduction (AC), preoperative bone conduction (BC), and postoperative aided thresholds were compared. Pure-tone averages (PTA), air-bone gap (ABG), and functional gain were calculated. Surgical complications and patient satisfaction were summarized from the chart review.Results:Sixteen patients (20 implants) met the inclusion criteria. The average age at the time of implantation was 12.9 ± 2.4 years. The preoperative AC and BC thresholds were 64.4 dB (±11.9 dB) and 7.9 dB (±4.90 dB), respectively, with an average ABG of 56.5 dB (±12.8 dB). The average postoperative aided threshold was 21.2 dB (± 4.25 dB) with a mean functional gain of 43.1 dB (±10.2 dB). One patient developed seroma postoperatively, which was treated conservatively. No other complications were reported over a mean follow-up time of 7.1 ± 4 months. For 13 patients with previous passive bone conduction implants or devices, the Osia system was universally favored.Conclusions:The new active transcutaneous bone conduction system showed favorable early clinical and audiometric outcomes. Repeated processor connectivity issues represent a potential area for future device development. This is the largest pediatric case series to date.Level of Evidence: Level 4—Retrospective Review.

PurposeObesity is a complex and multifactorial disease identified as a global epidemic. Convergent evidence indicates that obesity differentially influences patients with neuropsychiatric disorders providing a basis for hypothesizing that obesity alters brain structure and function associated with the brain’s propensity toward disturbances in mood and cognition. Herein, we characterize alterations in brain structures and networks among obese subjects (ie, body mass index [BMI] ≥30 kg/m2) when compared with non-obese controls.Patients and methodsWe obtained noninvasive diffusion tensor imaging and generalized q-sampling imaging scans of 20 obese subjects (BMI=37.9±5.2 SD) and 30 non-obese controls (BMI=22.6±3.4 SD). Graph theoretical analysis and network-based statistical analysis were performed to assess structural and functional differences between groups. We additionally assessed for correlations between diffusion indices, BMI, and anxiety and depressive symptom severity (ie, Hospital Anxiety and Depression Scale total score).ResultsThe diffusion indices of the posterior limb of the internal capsule, corona radiata, and superior longitudinal fasciculus were significantly lower among obese subjects when compared with controls. Moreover, obese subjects were more likely to report anxiety and depressive symptoms. There were fewer structural network connections observed in obese subjects compared with non-obese controls. Topological measures of clustering coefficient (C), local efficiency (Elocal), global efficiency (Eglobal), and transitivity were significantly lower among obese subjects. Similarly, three sub-networks were identified to have decreased structural connectivity among frontal–temporal regions in obese subjects compared with non-obese controls.ConclusionWe extend knowledge further by delineating structural interconnectivity alterations within and across brain regions that are adversely affected in individuals who are obese.

Bacteria can grow as free-floating, planktonic bacteria or complex communities called biofilms. Biofilms promote bacterial growth and diversity and offer bacteria unique environments, including aerobic and anaerobic layers, that facilitate resistance to antimicrobial therapies. Respiratory and related structures provide ideal environments for the development of bacterial biofilms, which predispose patients to recurrent and chronic infections. Biofilms are important for the persistence of chronic rhinosinusitis, pulmonary infections in cystic fibrosis, chronic otitis media, and device-related infections. Antimicrobial therapy that is proven effective against planktonic bacteria is often insufficiently effective against the defenses of biofilms. Furthermore, biofilms modify themselves following exposure to antimicrobial therapy, thus developing increased resistance. Understanding the nature of biofilms in common pediatric infections is essential to comprehending the expected course of bacterial illness and identifying treatments that are most likely to be beneficial against more resistant biofilms.

Objective To develop an expert consensus statement regarding persistent pediatric obstructive sleep apnea (OSA) focused on quality improvement and clarification of controversies. Persistent OSA was defined as OSA after adenotonsillectomy or OSA after tonsillectomy when adenoids are not enlarged. Methods An expert panel of clinicians, nominated by stakeholder organizations, used the published consensus statement methodology from the American Academy of Otolaryngology‐Head and Neck Surgery to develop statements for a target population of children aged 2‐18 years. A medical librarian systematically searched the literature used as a basis for the clinical statements. A modified Delphi method was used to distill expert opinion and compose statements that met a standardized definition of consensus. Duplicate statements were combined prior to the final Delphi survey. Results After 3 iterative Delphi surveys, 34 statements met the criteria for consensus, while 18 statements did not. The clinical statements were grouped into 7 categories: general, patient assessment, management of patients with obesity, medical management, drug‐induced sleep endoscopy, surgical management, and postoperative care. Conclusion The panel reached a consensus for 34 statements related to the assessment, management and postoperative care of children with persistent OSA. These statements can be used to establish care algorithms, improve clinical care, and identify areas that would benefit from future research.

Objectives/Hypothesis: To further clinically characterize lingual hamartomas, and to consolidate literature by analyzing clinical presentation, diagnostic evaluation, treatment, and outcomes.Study Design: Retrospective chart review and literature review. Methods: Case series from 1989 to 2020 at a tertiary pediatric center; follow-up ranging from 2 months to 12 years. Patient demographics, clinical presentations, physical examination findings, surgical pathology, operative methods, preoperative imaging, and follow-up. A review of English-language literature from 1945 to 2020 was conducted.Results: Seven patients (four male, three female) with nine lingual hamartomas were identified. Average age at surgical excision was 7.9 months (SD 3.5 months, range 3 to 14 months). Follow-up ranged from 2 months to 12 years, with all patients having no recurrence. Physical examination identified five pedunculated hamartomas and two sessile hamartomas. One patient had a neck CT, one had neck ultrasound, and two had facial MRIs. CT and ultrasounds confirmed presence of cervical thyroid. MRI suggested no muscular invasion for one patient, whereas motion artifact obscured findings for the other patient. Most patients who presented with dysphagia or poor weight gain achieved post-surgical improvement. The present cases combined with the literature review identified 57 patients with 63 lingual hamartomas.Conclusions: Lingual hamartomas appear as hypovascular pedunculated masses near the foramen cecum. There is no demographic predisposition, and most are identified during infancy. Imaging is not necessary, unless there is concern for lingual thyroid, in which case thyroid ultrasound should be performed. Surgical excision is curative, with dysphagia resolution and low likelihood for recurrence.

Auricular reconstruction with autologous rib cartilage involves using a soft tissue envelope to cover the cartilage framework. In patients with a low hairline, hair-bearing skin may be incorporated on the reconstructed ear, creating a difficult and conspicuous aesthetic problem. A retrospective chart review was conducted to summarize and share the experience of using the Candela GentleMax Pro 755-nm alexandrite laser system (Candela Corp) in children following auricular reconstruction. Nine patients received laser hair removal via the alexandrite laser system with good results. The number of completed sessions ranged from 1 to 5. The procedures were completed without the need for premedication or procedural sedation. Laser hair removal with an alexandrite laser system was safe, fast, and effective. With multistage auricular reconstruction, it was feasible to incorporate laser hair removal between the stages.
