Vocal cord paralysis after cardiovascular surgery in children: incidence, risk factors and diagnostic options.

OBJECTIVES: The aim of this study was to assess the incidence of vocal cord paralysis (VCP) in children after cardiovascular surgery. The secondary aims were to identify the factors potentially associated with VCP and to assess the diagnostic utility of laryngeal ultrasound (US). METHODS: This study is a retrospective review of patients who underwent aortic repair, patent ductus arteriosus ligation and left pulmonary artery surgeries from 2007 to 2017. The following data were collected: patient demographics, gestational age, weight and age at surgery, comorbidities, cardiovascular anomaly and type of procedure, laryngoscopic and US evaluation results. Univariable and multivariable logistic regression models were used to identify the variables associated with VCP. RESULTS: Two hundred and six patients were included in the study. Seventy-two patients (35%) were preterm and 32.5% showed comorbidities. At surgery, median age and weight were 0.6 months [interquartile range (IQR) 0.3-2.1] and 3.0 kg (IQR 1.3-4.0), respectively. Postoperatively, symptomatic patients underwent endoscopic evaluation and VCP was detected in 25 cases (12.1%). Laryngeal US was performed in 8 of these showing an excellent diagnostic relationship. On univariable analysis, factors significantly associated with VCP were prematurity, young age and lower weight at surgery and the presence of comorbidities. The presence of comorbidities and weight at surgery exhibited a significant risk of developing VCP postoperatively on multivariable analysis. CONCLUSIONS: VCP is not an unusual complication of cardiovascular surgery. Certain factors were associated with VCP development but only the presence of comorbidities and weight at surgery were statistically significant on multivariable analysis. Flexible laryngoscopy is the standard diagnostic technique and laryngeal US appears to be a reliable complement.

Bilateral tuberculous otomastoiditis in an immmunocompetent 5-year-old child: CT and MRI findings (2009: 3b).

Bilateral tuberculous mastoiditis (TOM) in an immunocompetent child is a very uncommon form of tuberculous infection presentation. This report shows the CT and MR imaging of bilateral tuberculous otomastoiditis consisting of aggressive signs of middle ear and mastoid involvement with bony destruction and periauricular collections with no signs of brain involvement. Differential diagnosis at pediatric age of destructive lesions such as mainly aggressive forms of histiocytosis is underscored. This form of bilateral TOM at this early age has not been described from a radiological perspective.

Congenital subglottic web: a rare cause of neonatal stridor.

Laryngeal web is a rare malformation caused by an anomalous embryologic development of the primitive larynx. Most of the reported cases are of the glottic type; the subglottic web is extremely rare. Laryngotracheobronchoscopy plays an essential role in the diagnostic workup of this lesion, and endolaryngeal resection is the preferred treatment whenever a structural cartilaginous subglottic stenosis is not present. The authors present the case of a neonate with a subglottic web diagnosed soon after birth. Management of this rare entity is discussed.

Safety of outpatient tonsillectomy in children: a review of 6 years in a tertiary hospital experience.

OBJECTIVE: We present our experience with outpatient tonsillectomy in children and critically review safety to support the outpatient policy. STUDY DESIGN AND SETTING: We conducted a retrospective chart review from January 1995 through December 2000 in the pediatric otolaryngology unit of a tertiary care university hospital. RESULTS: One thousand two hundred forty-three patients were accepted in the outpatient program with permissive criteria. Postoperative observation time ranged from 3 to 5 hours (median, 4.5 hours). The overall rate of complications was 9.3% (n = 116). Primary and secondary bleeding rates were 6.27% (n = 78) and 0.48% (n = 6), respectively. Thirty-six children (2.9%) had major bleeding; 2 of them were not identified in day-hospital (0.16%). Discharge was delayed in 103 patients (8.3%), and 13 patients showed complications after discharge (about 1% readmission rate). CONCLUSION: Our program outcomes support safety. Outpatient surgery is meant to provide comfort to the patient and efficiency to the health care system, without impairing safety; in our experience, most tonsillectomies in children comply with these objectives. SIGNIFICANCE: Outpatient tonsillectomy in children may be safe even with permissive criteria, when an appropriate setting is available.
