Injection Laryngoplasty for Children with Dysphagia after Cardiac Surgery.

Objective: To determine whether injection laryngoplasty (IL) resolves thin liquid aspiration among children with unilateral vocal cord paralysis (UVCP) after cardiac surgery. Study Design: Retrospective case-control. Setting: Tertiary children's hospital. Methods: Consecutive children (<5 years) between 2012 and 2022 with UVCP after cardiac surgery were included. Resolution of thin liquid aspiration after IL versus observation was determined for children obtaining videofluoroscopic swallow studies (VFSS). Results: A total of 32 children with left UVCP after cardiac surgery met inclusion. Initial surgeries were N = 9 (28%) patent ductus arteriosus ligations, N = 7 (22%) aortic arch surgeries, N = 9 (28%) surgeries for hypoplastic left heart syndrome, and N = 7 (22%) other cardiac surgeries. The mean age at initial surgery was 1.8 months (SD: 3.7). All children had a VFSS obtained after surgery that confirmed aspiration. There were 17 children that obtained an IL at 33.6 months (SD: 20.9) after cardiac surgery and 15 children observed without IL procedure. No surgical complications after IL were noted. The rate of aspiration resolution based on postoperative VFSS was N = 14 (82%) for the IL group and N = 9 (60%) for the control group P = .24. Documented VFSS aspiration resolution after cardiac surgery occurred by 9.6 months (SD: 10.0) in the observation group and 47.4 months (SD: 24.1) in the IL group (P < .001). Conclusion: IL can help treat aspiration in children with UVCP after cardiac surgery but the benefit beyond observation remains unclear. Future studies should continue to explore the utility for IL in managing dysphagia in this pediatric population.

Tracheal A-frame deformity and suprastomal collapse after pediatric tracheostomy.

Objectives: To determine the incidence of A-frame deformity and suprastomal collapse after pediatric tracheostomy. Study design: Retrospective cohort. Methods: All patients (<18 years) that had a tracheostomy placed at a tertiary institution between 2015 and 2020 were included. Children without a surveillance bronchoscopy at least 6 months after tracheostomy were excluded. Operative reports identified tracheal A-frame deformity or suprastomal collapse. Results: A total of 175 children met inclusion with 18% (N = 32) developing A-frame deformity within a mean of 35.8 months (SD: 19.4) after tracheostomy. For 18 children (18/32, 56%), A-frame developed within a mean of 11.3 months (SD: 15.7) after decannulation. There were 96 children developing suprastomal collapse (55%) by a mean of 17.7 months (SD: 14.2) after tracheostomy. All suprastomal collapse was identified prior to decannulation. Older age at tracheostomy was associated with a lower likelihood of collapse (OR: 0.92, 95% CI: 0.86-0.99, p = .03). The estimated 5-year incidence of A-frame deformity after tracheostomy was 32.8% (95% CI: 23.0-45.3) and the 3-year incidence after decannulation was 36.1% (95% CI: 24.0-51.8). Highly complex children had an earlier time to A-frame development (p = .04). At 5 years after tracheostomy, the estimated rate of suprastomal collapse was 73.7% (95% CI: 63.8-82.8). Conclusions: Tracheal A-frame deformity is estimated to occur in 36% of children within 3 years after tracheostomy decannulation. Suprastomal collapse, which approaches 74% at 5 years after tracheostomy, is more common when tracheostomy is placed at a younger age. Surgeons caring for tracheostomy-dependent children should recognize acquired airway obstruction and appropriately monitor these outcomes. Level of evidence: 3.

Surgical Outcomes by Early Airway Endoscopy Findings after Pediatric Staged Laryngotracheoplasty.

OBJECTIVES: To determine how initial postoperative airway endoscopy findings after stent removal predict successful decannulation in children undergoing double-staged laryngotracheoplasty (dsLTP). Secondary objectives assessed timing of decannulation and number of endoscopic interventions needed after dsLTP. METHODS: A case series with chart review included children who underwent dsLTP at a tertiary children's hospital between 2008 and 2021. Rates of decannulation, time to decannulation, and number of interventions after dsLTP were recorded for children with high- or low-grade stenosis at the first bronchoscopy after stent removal. RESULTS: Of the 65 children who were included, 88% had high-grade stenosis and 98% had a preoperative tracheostomy. Successful decannulation happened in 74% of the children, and 44% of the children were decannulated within 12 months of surgery. For children with low-grade stenosis at the first endoscopy after stent removal, 84% were successfully decannulated compared with 36% of the children with high-grade stenosis (p = 0.001). After dsLTP, children with high-grade stenosis required 7.5 interventions (SD: 3.3) compared with 4.0 interventions (SD: 3.0) for children with low-grade stenosis (p < 0.001). Decannulated children with high-grade stenosis necessitated more endoscopic procedures (7.0 vs. 3.7, p = 0.02). Time to decannulation was similar between children with high- and low-grade early postoperative stenosis (21.9 vs. 17.8 months, p = 0.63). CONCLUSIONS: Higher grade stenosis identified on the first airway endoscopy after suprastomal stent removal is correlated with lower decannulation rates and more postoperative endoscopic interventions. Although time to decannulation was not impacted by early stenosis grade, surgeons might utilize these early airway findings to counsel families and prognosticate possible surgical success.

Neighborhood Socioeconomic Disadvantage and Long-Term Outcomes After Pediatric Tracheostomy.

OBJECTIVES: To determine whether long-term outcomes after pediatric tracheostomy are impacted by neighborhood socioeconomic disadvantage. METHODS: A prospective cohort of children with tracheostomies was followed at an academic pediatric hospital between 2015 and 2020. Patients were grouped into low or high socioeconomic disadvantage using their neighborhood area deprivation index (ADI). Survival and logistic regression analyses determined the relationship between ADI group, decannulation, and mortality. RESULTS: A total of 260 children were included with a median age at tracheostomy of 6.6 months (interquartile range [IQR], 3.9-42.3). The cohort was 53% male (N = 138), 55% White race (N = 143), and 35% Black or African American (N = 90). Tracheostomy was most frequently indicated for respiratory failure (N = 189, 73%). High neighborhood socioeconomic disadvantage was noted for 66% of children (N = 172) and 61% (N = 158) had severe neurocognitive disability. ADI was not associated with time to decannulation (HR = 0.90, 95% confidence interval [95% CI]: 0.53-1.53) or time to death (HR = 0.92, 95% CI: 0.49-1.72). CONCLUSIONS: Neighborhood socioeconomic disadvantage was not associated with decannulation or mortality among children with a tracheostomy. These findings suggest that long-term outcomes after pediatric tracheostomy are less dependent on socioeconomic factors in an individual community.

Pediatric tracheostomy audiometric outcomes - A quality improvement initiative.

OBJECTIVE: Pediatric tracheostomy patients disproportionately experience hearing loss and are at risk for delayed identification due to their medical complexity. Nonetheless, protocols to monitor hearing in these children are lacking. This quality improvement (QI) initiative aimed to increase the rates of audiometric testing within 12 months of pediatric tracheostomy placement. METHODS: A retrospective cohort study included children who underwent tracheostomy under 18 months of age between 2012 and 2020. Rates of audiometric assessments before and after QI project implementation (2015) were reported along with hearing loss characteristics. RESULTS: A total of 253 children met inclusion. Before project initiation (2012-2014), 32% of children (28/87) obtained audiometric testing within 12 months after tracheostomy. During the first three years of implementation (2015-2017), 39% (38/97) were tested, while 55% (38/69) were tested during the subsequent three years (2018-2020) (P = .01). A passing newborn hearing screen was obtained for 70% of the 210 children with a recorded result, and 198 survived at least 12 months to receive audiometric testing at a median of 11.3 months (IQR: 6.2-22.8) after tracheostomy. Hearing loss was identified for 44% of children (N = 88), of which 42 children initially passed newborn hearing screen. A second assessment was obtained for 62% of children (123/198) at a median of 11.3 months (IQR: 4.5-17.5) after the initial test. In this group, 23% with a previously normal audiometric exam were found to have hearing loss (15/66). CONCLUSIONS: QI initiatives designed to monitor hearing loss in children with a tracheostomy can result in improved rates of audiometric assessments. This population has disproportionately high rates of hearing loss, including delayed onset hearing loss making audiometric protocols valuable to address speech and language development delays.

Vocal Fold Paralysis Secondary to Subclavian Venous Thrombosis.

The etiology of vocal fold paralysis is multifaceted. One of the rare causes is internal jugular vein thrombosis secondary to central venous catheterization. The palsy is usually ipsilateral to the site of indwelled catheterization, self-limited and reversible. The authors of this manuscript report a rare case of contralateral recurrent laryngeal nerve palsy induced by subclavian vein thrombosis following central venous catheterization. The patient developed irreversible vocal fold paralysis that necessitated office-based injection laryngoplasty.

Delayed Periorbital Reconstruction After War Injuries.

INTRODUCTION: Syrian patients injured in the war frequently undergo rudimentary primary wound closure in combat zones. These patients are later transferred to Lebanon where their wounds need to be secondarily managed. This often leads to the creation of unorthodox approaches for reconstruction of orbital injuries. CASE PRESENTATION: The authors of this manuscript demonstrate a few cases of peri-ocular trauma with a delayed presentation, in which adaptations of conventional reconstructive methods had to be implemented had to be undertaken for optimal results. CONCLUSION: Modified techniques for reconstruction of peri-ocular injuries with delayed presentation are discussed in this paper. The patients are cases of trauma secondary to war in the region of Lebanon and Syria. The unique presentations of these patients have led to the use of "opportunity flaps" surrounding highly fibrotic and scarred tissue, in an attempt to allow for delayed reconstruction.

HPV-related oropharyngeal cancer prevalence in a middle eastern population using E6/E7 PCR.

BACKGROUND: Given the paucity of data and widely variable rates that have been reported, the main objective of this study was to examine the prevalence of HPV-positivity in oropharyngeal squamous cell carcinoma (OPSCC) in Middle Eastern patients presenting to one of the region's largest tertiary care centers using polymerase chain reaction (PCR) amplification of the HPV E6/E7 oncogenes, a highly sensitive and specific method of detection. METHODS: Medical charts and archived pathological specimens were obtained for patients diagnosed with biopsy proven oropharyngeal cancer who presented to the American University of Beirut Medical Center between 1972 and 2017. DNA was extracted from paraffin-embedded specimens and tested for 30 high-risk and low-risk papilloma viruses using the PCR-based EUROarray HPV kit (EuroImmun). RESULTS: A total of 57 patients with oropharyngeal cancer were initially identified; only 34 met inclusion/exclusion criteria and were included in the present study. Most patients were males (73.5%) from Lebanon (79.4%). The most common primary tumor site was in the base of tongue (50%), followed by the tonsil (41.2%). The majority of patients (85.3%) tested positive for HPV DNA. CONCLUSION: The prevalence of HPV-positivity amongst Middle Eastern OPSCC patients, specifically those from Lebanon, may be far greater than previously thought. The Lebanese population and other neighboring Middle Eastern countries may require a more vigilant approach towards HPV detection and awareness. On an international level, further research is required to better elucidate non-classical mechanisms of HPV exposure and transmission.

Simultaneous Brucella breast and pacemaker infection.

Infection with Brucella spp. is endemic to the Middle East and the eastern Mediterranean basin. Brucellosis can mimic infectious and non-infectious febrile illnesses and therefore it can pose a diagnostic challenge. A wide range of deep-seated infections have been ascribed to brucellosis including breast abscesses and infections of prosthetic endovascular devices. The latter are usually rare but difficult to treat short of excision of the infected device. Here, we present the case of a middle-aged Lebanese woman who presented with simultaneous breast abscesses and a pacemaker infection due to brucellosis. To our knowledge, a similar manifestation has not been reported in the literature.
