Surgical management of vocal cord nodules in children: Trends and outcomes.

OBJECTIVES: Vocal cord nodules (VCNs) are the most common cause of dysphonia in school-aged children, with potential negative impacts on quality of life including diminished self-esteem and academic performance. The standard of care for VCNs is conservative management which ranges from voice hygiene to speech therapy with a focus on voice otherwise known as voice therapy, with surgical excision reserved for refractory cases. Thus, few studies have analyzed outcomes of surgical management of VCNs. The purpose of this study is to assess the prevalence and efficacy of surgical excision of VCNs when compared to speech therapy. METHODS: Children with VCNs seen at a single tertiary care institution between 2015 and 2020 were identified by ICD-9 code 478.5 and ICD-10 code J38.2. Demographics, objective voice assessment, intervention, and follow-up assessment data were reviewed. Frequencies, medians, and interquartile ranges were calculated. Time to resolution and improvement were assessed by Cox proportional hazards model. Univariate logistic regression was performed. A P value of <0.05 was considered statistically significant. RESULTS: Three hundred sixty-eight patients diagnosed with VCNs were identified. 169 patients received intervention for VCNs, with 159 (43.2 %) receiving speech therapy alone and 5 (1.4 %) receiving surgery alone. On bivariate analysis, there was no significant difference in demographic features between treatment groups, however speech therapy patients did have a longer follow-up time. 154 patients underwent objective voice assessment at the time of VCN diagnosis. Among these patients, 95 (61.7 %) received speech therapy and 59 (40.3 %) received no intervention. Speech therapy patients had significantly higher pVHI scores, however there was no significant difference in CAPE-V Overall Severity scores or computerized voice assessment analysis. On Cox proportional hazards analysis, surgical intervention was associated with faster resolution and faster improvement of dysphonic symptoms. On binary logistic regression, surgery was associated with a significantly greater proportion of patients reporting resolution of dysphonic symptoms, however there was no significant difference in proportion of patients reporting improvement of dysphonia. CONCLUSION: For most patients with VCNs, conservative measures such as voice hygiene and speech therapy remain first line, however certain patients may benefit from the rapid improvement and resolution of symptoms that surgical intervention may provide.

Visual outcomes following orbital decompression for orbital infections.

OBJECTIVE: To analyze the visual outcomes and sequelae of endonasal intervention for orbital infections. INTRODUCTION: Orbital infections pose a serious threat to vision in the pediatric population and can result in complications such as blindness, diplopia, intracranial involvement, and death. [1] Orbital decompression by endonasal intervention is a common treatment to address a variety of orbital infections including orbital cellulitis, orbital abscesses, and subperiosteal abscesses. [2] The outcomes of visual sequelae such as loss or limitation of visual acuity, extraocular movements, and increased intraocular pressure following orbital decompression via endonasal intervention have not been sufficiently investigated in the current literature. METHODS: This retrospective cohort study was performed at our tertiary care pediatric hospital using data from 69 patients aged 0-18 years who were admitted between 2008 and 2018. Data was extracted from the electronic medical record system. RESULTS: Following endoscopic sinus surgery, symptoms of orbital infection improved throughout the cohort. Improvement in visual acuity is demonstrated by a statistically significant decrease in the average logMAR value in both the right and left eye (P = 0.002 and P = 0.028 respectively). There was also a significant improvement to normal values postoperatively for patients who initially presented with abnormal tonometry, extraocular movement, and the appearance of eyelids and eyelashes. CONCLUSION: There is no decline or loss of vision with otolaryngology surgical intervention for orbital cellulitis in our cohort. This retrospective chart review demonstrates the efficacy of surgical intervention on overall visual outcomes following endonasal intervention for orbital infections such as orbital cellulitis, orbital abscesses, and subperiosteal abscesses.

Chronic mild stress leads to anxiety-like behavior and decreased p70 S6K1 activity in the hippocampus of male mice.

Major affective disorders are highly prevalent, however, current treatments are limited in their effectiveness due to a lack of understanding of underlying molecular mechanisms. Recent studies have shown that reduced activity of p70 S6 kinase 1 (S6K1), a downstream target of the mechanistic target of rapamycin complex 1 (mTORC1), is linked to anxiety-like behavior in both humans and rodents. The purpose of this study was to investigate the relationship between S6K1 and anxiety-like behavior following chronic mild stress (CMS) and drug-induced inhibition of S6K1. Following CMS, anxiety-like behavior was evaluated using an open field (OF) and elevated plus maze (EPM) in adult male C57/Bl6 mice. After behavior analysis, samples of the hippocampus were harvested for quantification of S6K1, S6 ribosomal protein, glycogen synthase kinase-3 ß (GSK3ß), and beta tubulin via western blot. Our results demonstrate that CMS mice exhibit anxiety-like behavior in the OF and EPM and reduced activity of S6K1 in the hippocampus (HPC). We measured phosphorylation levels of GSK3ß and found that GSK3ß phosphorylation was also reduced following CMS compared to control mice. Furthermore, pharmacological inhibition of S6K1 with PF-4708671 in male mice was sufficient to produce anxiety-like behavior in the OF and EPM. These results further support the significant role of S6K1 in the pathogenesis of anxiety and affective disorders.

Effect of injection laryngoplasty material on outcomes in pediatric vocal fold paralysis.

Background: While injection laryngoplasty is becoming increasingly common in children, there has not been clearly established guidelines for the choice of injection material. This study evaluates for variability in post-surgical outcomes between different materials used for injection laryngoplasty in the treatment of pediatric unilateral vocal cord paralysis. Methods: In this cohort study, a retrospective chart review was performed for all patients undergoing injection laryngoplasty for unilateral vocal cord paralysis at our tertiary-care children's hospital between January 2010 and December 2019. Patients with vocal cord paresis or bilateral vocal cord paralysis were excluded from this study. Demographics, pre- and post-injection clinic visits, and operative reports were reviewed to compare outcomes between injection materials, including the number of injections required, inter-surgical interval, and rate of vocal improvement. Results: Forty-four patients were included in the analysis. Half of the patients were female, and half were male. A total of 97 injections were observed, with 32 patients receiving multiple injections. The mean age at first injection was 7 years. The most common causes of vocal fold paralysis were iatrogenic (n=21, 48%) and idiopathic (n=9, 20%). Thirty-nine percent (n=17) had a history of cardiac surgery. Forty-five percent of injections used Radiesse® voice/Prolaryn® plus, 35% used Radiesse®/Prolaryn® voice Gel, and 20% used Cymetra™. The material used was not associated with a difference in post-operative outcomes, including number of injections, (P=0.10; 0.29), inter-surgical interval (P=0.27; 0.29), or rate of voice improvement (P=0.86; 0.36). Conclusions: Neither material choice nor demographic factors were associated with a difference in outcomes following injection laryngoplasty or a change in the inter-surgical interval. Further research is needed to develop standardized protocols for injection laryngoplasty in this population.

Tolerance of one-way in-line speaking valve trials in ventilator dependent children.

BACKGROUND: Despite the advantages of tracheostomy placement in children requiring prolonged mechanical ventilation, vocalization and verbal communication remains limited in this population of children. The lack of these essential elements during a critical period of development can have a negative impact on overall development. In ventilator dependent children, in-line speaking valves (ISV) provide an opportunity for initiating speech and communication. The objective of this study is to examine patient characteristics and risk factors associated with tolerance and success of ISV trials performed with mechanically ventilated children. METHODS: A retrospective cohort study was conducted at a large, tertiary care children's hospital to evaluate the outcomes of ISV trials in ventilator-dependent children with tracheostomies, from 2009 to 2019. The primary endpoints were tolerance of the initial ISV assessment, and successful completion of a trial. We compared demographic and clinical characteristics among children that had a successful ISV trial to those that did not. RESULTS: Eighty-nine patients were included, 56 (62%) were male and 33 (38%) were female. Overall, 76 (85%) patients completed an ISV assessment and trial successfully during their hospitalization. The number of attempts before completing a successful trial varied with 41 (46%) patients succeeding on the first attempt. Children that underwent a tracheostomy for airway obstruction were more likely to fail. CONCLUSIONS: Ventilator-dependent children with complex comorbidities demonstrate excellent tolerance of in-line speaking valves. Patients should be selected for ISV trials in a multidisciplinary setting. Airway obstruction as an indication for tracheostomy placement is a significant predictor of failure for ISV trials.

Using the Craniovertebral Angle to Quantify Intraoperative Ergonomic Risk.

OBJECTIVE: To measure the craniovertebral angle during tonsillectomy, assess the interrater reliability of our methodology, and investigate the correlations of the Rapid Upper Limb Assessment and the craniovertebral angle to quantify ergonomic risk. STUDY DESIGN: Prospective, observational study. SETTING: Tertiary care pediatric institution. METHODS: Neck posture was evaluated for 92 images with 7 surgeons. Lateral images of the surgeon were captured every minute in a standardized method. Images were assessed by 3 raters, measuring the craniovertebral angle, defined as the angle between a horizontal line through the C7 vertebrae and another line through C7 and the tragus of the ear. Interrater reliability of the craniovertebral angle was evaluated using the κ statistic. Per prior publications, reports of neck pain were frequent when the craniovertebral angle value was <50°; thus, we defined an abnormal posture if the craniovertebral angle was <50°. RESULTS: Mean (SD) craniovertebral angle during tonsillectomy was 26.0° (11.3°). One hundred percent of procedures had at least 1 assessment of abnormal posture. The lowest interrater reliability was 0.77 (CI: 0.67-0.87). Rapid Upper Limb Assessment and craniovertebral angle (CA) correlation was -0.12 (P = .27) and, therefore, null. CONCLUSION: Poor posture during tonsillectomy places otolaryngologists at intraoperative ergonomic risk. The craniovertebral angle is a predictor of future neck pain, and a pathologic neck position during tonsillectomy was identified. Given the high interrater reliability, our approach to assessing intraoperative surgical ergonomics was validated. Overall, RULA and the CA are not a substitute for one another but complementary.

Assessing the use of telehealth for the surgical management of recurrent otitis media.

OBJECTIVE: To compare the incidence of middle ear effusion (MEE) at the time of bilateral tympanostomy tube insertion (BTI) for recurrent acute otitis media (rAOM) patients initially seen in-office or via telehealth. METHODS: After obtaining IRB approval from Nationwide Children's Hospital, a total of 524 patients evaluated for rAOM were retrospectively reviewed after being divided into two cohorts: those seen via a telehealth visit from April to June of 2020 (n = 140), and those seen via an in-person visit from April to June of 2019 (n = 384). Recommendation for BTI was captured for each patient following their visit. Clinical characteristics documented at the time of the visit, such as history of intramuscular (IM) antibiotic use and hearing or speech concerns were also captured to determine whether both telehealth and in-person cohorts were similar in clinical presentation. For BTI patients, the presence or absence of MEE in either ear at the time of BTI was recorded. Patients with cleft palate or prior BTI were excluded. RESULTS: 51.43% (72/140) of patients in the telehealth cohort were recommended for BTI. Of those recommended, 87.50% (63/72) underwent BTI. Of these, 31.75% (20/63) had a MEE at the time of BTI. In the in-office cohort, 69.01% (265/384) of patients were recommended for BTI. Of those recommended, 92.83% (246/265) underwent BTI. Of these, 69.92% (172/246) had a MEE at the time of BTI. CONCLUSION: There were significantly less middle ear effusions in the telehealth cohort compared to the in-office cohort (p < 0.0001). It is well understood that telehealth is limited in its physical exam capabilities. It is possible that the use of telehealth for the surgical management of rAOM may lead to more procedures on patients without MEE.
