Objectives: (1) To investigate the prevalence and severity of drooling among healthy young children referred for adenotonsillectomy; (2) to evaluate the effect of adenotonsillectomy on drooling. Study Design: Prospective study. Setting: Tertiary referral center. Methods: Healthy typically developed children aged 18 to 48 months referred to adenotonsillectomy for upper airway obstruction (UAO) were recruited. Age‐matched children recruited from the community served as controls. Drooling frequency and severity were assessed at baseline and 2 months following surgery based on 2 subjective scales: the Drooling Infants and Preschoolers Scale (DRIPS) and Thomas‐Stonell and Greenberg Saliva Severity Scale (TSGS). Results: Eighty‐seven children aged 18 to 48 months were included in the study. Forty‐three children referred to adenotonsillectomy (study group) and 44 age‐matched controls. There were significant differences in almost all of the DRIPS items between children in the presurgery group compared to controls. Drooling severity and frequency were greater in the former compared to the latter (TGF‐s severity: 1.4 ± 1.0 vs 0.6 ± 0.8, P =.001; TGF frequency: 1.3 ± 0.9 vs 0.5 ± 0.6, P <.001). After surgery, the scores for all DRIPS and TSGS items decreased significantly and were comparable to the control group. Conclusions: The frequency and severity of drooling among otherwise young children referred for adenotonsillectomy were greater than those for healthy controls. Following surgery, both the frequency and severity significantly improved and became comparable to those of controls. These findings suggest that a major improvement in drooling is one of the benefits of a surgical intervention in a child with UAO. [ABSTRACT FROM AUTHOR]

Two nasal foreign bodies were discovered by a dental practitioner on a routine radiographic examination of a 15-year-old autistic patient. Going over past radiographs, one of the nasal foreign bodies was detected in a radiograph performed 2 years previously. No nasal complaints or other clues to the problem were apparent. The patient was referred to the emergency room, and the foreign bodies were removed by an Ear Nose and Throat specialist, under general anesthesia. This paper reviews the diagnosis and treatment of nasal foreign bodies, and highlights the important role of the dental practitioner in the proper detection and diagnosis, prompt referral for management, and reduction in related complications.

Objective: The value of pre-operative coagulation testing for adenotonsillar surgery is controversial. The purpose of this study was to evaluate the role of routine coagulation tests and a standardized questionnaire in children before tonsillectomy and/or adenoidectomy. Results: A total of 143 children were prospectively enrolled in the study between 2013 and 2017, 81 males (56.6%) and 62 females (43.4%), age range 1 to 18 years (median age 5 years). Eighteen bleeding events were documented, three of them required treatment in the operating room. Abnormal coagulation tests were not associated with higher odds of bleeding after surgery. Higher risk of bleeding (p = 0.01) was associated with an abnormal standardized medical questionnaire. [ABSTRACT FROM AUTHOR]

Background: Obstructive sleep apnea (OSA) occurs in 1%-4% of children; adenotonsillectomy is an effective treatment. Mortality/severe brain injury occurs among 0.6/10 000 adenotonsillectomies; in children, 60% are secondary to airway/respiratory events. Earlier studies identified that children aged <2 years, extremes of weight, with co-morbidities of craniofacial, neuromuscular, cardiac/respiratory disease, or severe OSA are at high risk for adverse post-operative respiratory events (AE). We aimed to: Firstly, investigate which risk factors were associated with AEs either in the post-anesthesia care unit (PACU), pediatric intensive care unit (PICU), or both in this population. Secondly, we investigated factors associated with post-operative PICU AE despite no event in the PACU in order to predict need of post-operative PICU after their PACU stay.Methods: Retrospective study of children admitted to the PICU after adenotonsillectomy between 08/2006-09/2015. Demographics, risk factors, and occurrence of AE (oxygen saturation <92, stridor, bronchospasm, pneumonia, pulmonary edema, re-intubation) were recorded.Results: During the studied time period 4029 tonsil/adenoid procedures were performed in 3997 children. 179, admitted to the PICU post-operatively, met criteria for analysis. PICU AEs occurred in 59%: 44%-83% in any particular risk category. PACU AEs occurred in 42%. Of those with PACU events: 92% suffered AEs in the PICU; however, 35% of those without a PACU AE still suffered a PICU AE.Conclusions: Among high-risk children undergoing TA, absence of adverse events in PACU during a 2-hour observation period does not predict absence of subsequent AEs in the PICU.

Objectives/hypothesis: Investigate the feasibility of soldering a free cartilage graft into a tracheal defect by laser heating and assessing the resulting burst pressure and thermal damage to the cartilage.Study Design: Animal study.Methods: A 20 × 8 mm defect was created in fresh cadaveric pig tracheas, a cartilage graft of the same size was harvested from the thyroid ala cartilage, and the graft was fitted into the defect. The soldering process involved covering the edges with liquid albumin and using a fiber-laser system for heating the edges to temperature T under temperature control. This was done for groups of grafts at various temperatures T = 60°C to 90°C. The tracheas were sealed, for each group the burst pressure was measured, and a histologic examination of the soldered incisions was performed.Results: The burst pressures were in the range of 66 to 409 mm Hg. The median burst pressure was 78, 157, 231, and 146 mm Hg, respectively, for T = 60°C, 70°C, 80°C, and 90°C. Statistical analysis revealed significant differences in burst pressures between the T = 60°C group and the T = 80°C and T = 90°C groups (P < .05). The highest burst pressure was measured in the T = 80°C group. Histologic examination revealed no thermal damage to the cartilage at this temperature.Conclusions: Performing a sutureless laser soldering of a free cartilage graft to a tracheal defect, achieving an immediate watertight bond, is feasible. At T = 80°C the highest burst pressures were achieved. No histologic damage was observed. In vivo studies are needed before implementation of this technique in laryngotracheopasty.Level Of Evidence: NA Laryngoscope, 129:58-62, 2019. [ABSTRACT FROM AUTHOR]

Introduction: Skull base lesions in children and adolescents are rare, and comprise only 5.6% of all skull base surgery. Anterior skull base lesions dominate, averaging slightly more than 50% of the cases. Until recently, surgery of the anterior skull base was dominated by open procedures and endoscopic skull base surgery was reserved for benign pathologies. Endoscopic skull base surgery is gradually gaining popularity. In spite of that, open skull base surgery is still considered the “gold standard” for the treatment of anterior skull base lesions, and it is the preferred approach in selected cases. Objective: This article reviews current concepts and open approaches to the anterior skull base in children in the era of endoscopic surgery. Materials and Methods Comprehensive literature review. Results: Extensive intracranial–intradural invasion, extensive orbital invasion, encasement of the optic nerve or the internal carotid artery, lateral supraorbital dural involvement and involvement of the anterior table of the frontal sinus or lateral portion of the frontal sinus precludes endoscopic surgery, and mandates open skull base surgery. The open approaches which are used most frequently for surgical resection of anterior skull base tumors are the transfacial/transmaxillary, subcranial, and subfrontal approaches. Reconstruction of anterior skull base defects is discussed in a separate article in this supplement. Discussion: Although endoscopic skull base surgery in children is gaining popularity in developed countries, in many cases open surgery is still required. In addition, in developing countries, which accounts for more than 80% of the world’s population, limited access to expensive equipment precludes the use of endoscopic surgery. Several open surgical approaches are still employed to resect anterior skull base lesions in the pediatric population. With this large armamentarium of surgical approaches, tailoring themost suitable approach to a specific lesion in regard to its nature, location, and extent is of utmost importance.

Adenoid hypertrophy is the most common cause of upper airway obstruction and sleep-disordered breathing in children, yet its pathogenesis remains unclear. The identification of the novel helper T cell subsets, Th17 cells and regulatory T cells (Tregs) could provide new insight into our understanding of the mechanisms involved in the development of this condition. The purpose of this study is to evaluate the adenoidal lymphocyte subsets to describe the percentage of various lymphocyte subsets in hypertrophied adenoids and correlate them with symptom severity. Twenty consecutive children undergoing adenoidectomy were included, and lymphocytes were isolated from their adenoids. T cell subpopulations were detected by flow cytometry using a fluoresceinated monoclonal antibody directed against a number of cell markers (CD4++, CD8++, CD25++, FOXP3 IL17++, and others). We found a significant negative linear correlation between the Th17/Treg ratio and the patients'' clinical scores (R == −−0.71 p < 0.005). The correlation was independent of age and gender. Decreased ratios of Th17/Treg subpopulations may play a role in the pathogenesis of adenoid hypertrophy. [ABSTRACT FROM AUTHOR]

Objectives: We describe the clinical characteristics and management of vocal fold paralysis in infants who were born with a tracheoesophageal fistula (TEA). Methods: This retrospective case series included all infants born with TEFs who presented to our pediatric otolaryngology unit and intensive care unit because of dyspnea or aphonia in the years 2005 and 2006, and who were found to have vocal fold paralysis. Results: Five boys and 1 girl were studied. One infant had stridor before TEA repair, and 5 after it. All children underwent flexible laryngotracheobronchoscopy and were treated in the pediatric intensive care unit before diagnosis of the vocal fold paralysis (5 bilaterally and 1 unilaterally) was made. The ages at diagnosis of paralysis ranged between 14 days and 14 months. Five infants required tracheostomy. Conclusions: Vocal fold paresis in infants is difficult to diagnose. The risk for recurrent laryngeal nerve injury associated with TEA and TEA repair should be emphasized in these children. We recommend that all newborns with TEA should be examined by an otolaryngologist before operation to confirm the mobility of the vocal folds and to rule out other associated airway malformations, and examined after operation if respiratory difficulties develop.

Objectives: Hyperkinetic laryngeal behaviors may be used to achieve glottal closure in the presence of vocal cord disorders. In adults, the Glottal Function Index (GFI) is a validated self-administered survey used to evaluate glottal insufficiency. In children, the relationships between glottal closure and vocal cord lesions have not been examined. We undertook to evaluate the efficacy of the GFI in detecting disorders of the vocal cords in children. Methods: We evaluated 100 consecutive children who underwent flexible fiberoptic laryngoscopy. A 4-item GFI questionnaire was administered to the parents of each study subject on study entry. The videotapes of the examinations were evaluated and scored by 3 investigators in a blinded manner. The GFI scores were compared in subjects with and without vocal cord findings. Results: The final analysis included 100 children 2 to 16 years of age. The mean age of the study group was 7.3 years (±3.9 years). Of the 100 patients, 54 had vocal cord disorders. The most common was vocal cord nodules, in most cases combined with bowing of the vocal cords; the two variables were highly correlated (p << .01). We performed a receiver operating characteristics test between the presence of vocal cord disorders and the GFI score. We found that the ‘optimal’ score, on which the sensitivity and specificity curves cross, was 3. Of the 54 patients who had vocal cord disorders, the index identified 38 patients (70%), whereas the patients' complaints identified only 30 patients (55.6%). This difference was statistically significant (p < .05). Conclusions: The GFI is a reliable 4-item symptom index with excellent correlation to the presence of vocal cord lesions in children.

Described is a 15-year-old boy who presented with an ulcerative destructive soft palate lesion, skin lesions, and prolonged history of weakness and abdominal pain associated with abnormal liver functions.A midline destructive lesion was considered. However biopsies revealed chronic inflammation. After thorough investigation including colon, liver, skin and uvular biopsies a diagnosis of Inflammatory Bowel Disease in association of Autoimmune Sclerosing Cholangitis was made. Treatment with steroids improved his symptoms, normalized liver functions and enhanced healing of the skin and palatal lesions.This case demonstrates the involvement of the palate in a rare systemic disease and to our knowledge is the first description of Sclerosing Cholangitis presenting as an ulcerative lesion of the soft palate.

Objective: To define the etiology, management and prevention of iatrogenic neonatal nasal obstruction caused by intra-nasal synechia (INS). Design: Case series retrospectively reviewed, years 2001–2002. Setting: Tertiary care children’s hospital Patients: Four neonates, ages 2 weeks to 3 months, evaluated for nasal obstruction and consequent respiratory distress. Endoscopic findings were of intra-nasal synechia caused by previous intra-nasal invasive interventions. Main outcome measures: The procedures inciting the formation of synechia, possible management problems leading to synechia formation, clinical presentation, treatment and results of treatment were documented. Results: Initial incorrect diagnosis and management with an inappropriate intervention was found to be a possible cause of nasal obstruction due to synechia formation in three of these patients (two with associated craniofacial anomalies). In one patient complete nasal obstruction due to synechia was a result of continuous positive airway pressure (CPAP) intra-nasal catheters. Treatment including endoscopic synechiolysis resulted in an improved airway but not a complete cure. All patients required multiple procedures to attain a satisfactory nasal airway. Conclusion: Careful initial diagnosis and management of neonatal nasal obstruction may prevent severe complications caused by synechia in the nasal cavity. [Copyright &y& Elsevier]

Objective: To determine if children with neurological impairment are at additional risk for foreign body aspiration or impaction and if they present with a different clinical course than normal children. Design: Retrospective cohort study. Setting: Tertiary care children''s hospital. Patients and other participants: A retrospective chart review of 328 consecutive procedures for aero-digestive foreign body removal over a 6 year period was performed. Of these patients 52 (15.9%) were identified with neurological impairment. Results: Compared with the non-impaired children, those with neurological impairment were older, diagnosed later, hospitalized longer and had a higher incidence of complications. Conclusion: A greater index of suspicion is needed to timely treat aero-digestive foreign bodies in children with neurological impairment. These children may not be receiving the necessary attention when presenting with non-specific symptoms. [Copyright &y& Elsevier]

Described is a 2-year-old child who required a tracheotomy for an obstructing laryngeal tumor. Post-operatively the child responded with extreme anxiety and refused to cooperate with tracheostomy care including suctioning, tie changing and cannula change. A novel approach was attempted. We performed a tracheotomy on the child''s favorite doll and taught her to perform all the necessary tracheostomy care on the doll. Once the child became accustomed to treating the doll, it became much easier to care for her tracheostomy and compliance to treatment improved greatly to the point were restraint was no longer required. This model of mock surgery and care of a child''s doll may be helpful in treating young children with tracheotomies. [Copyright &y& Elsevier]

Background: Enlarged tonsils and adenoids are the major etiology of obstructive sleep apnea (OSA) in children. Lymphatic hyperplasia is common to both OSA and celiac disease. We aimed to investigate the effect of a gluten-free diet on OSA symptoms in children with celiac disease.Methods: Children with celiac disease aged 2-18 years were prospectively recruited before the initiation of a gluten-free diet. Children with negative celiac serology who underwent gastrointestinal endoscopies for other indications served as controls. All participants completed a validated OSA-related symptoms questionnaire and the pediatric sleep questionnaire (PSQ) at baseline and 6 months later.Results: Thirty-four children with celiac disease (mean age 6.6 ± 3.5 years) and 24 controls (mean age 7.3 ± 4.6 years, P = 0.5) were recruited. There were no significant differences in gender, body mass index or season at recruitment between the two groups. The rate of positive PSQ scores was higher (more OSA-related symptoms) in the control group compared to the celiac group, both at recruitment and at the 6-month follow-up (33.3% vs. 11.8%, P = 0.046, and 16.7% vs. 0, P = 0.014, respectively). PSQ scores improved significantly in both groups at the 6-month follow-up (P < 0.001 for both). Improvement was significantly higher in the celiac group compared to controls (0.1 ± 0.09 vs.0.06 ± 0.06, respectively, P = 0.04).Conclusions: Children with celiac disease had fewer OSA-related symptoms than controls, but the degree of improvement following the initiation of a gluten-free diet was significantly higher. These findings suggest that a gluten-free diet may improve OSA-related symptoms in children with celiac disease. [ABSTRACT FROM AUTHOR]

BACKGROUND: To evaluate chorda tympani nerve function as measured by unilateral increases of gustatory thresholds in the presence of ipsilateral acute otitis media. METHODS: Prospective clinical study comparing electrogustometric measurements was conducted to evaluate the taste thresholds of each side of the tongue in a patient during an acute episode of unilateral acute otitis media. Included were patients aged 12-40 who presented to the emergency department and outpatient ear, nose, and throat clinic of a university-affiliate tertiary medical center with unilateral acute otitis media between January 2019 and January 2020 and consented to the study. RESULTS: Eleven patients were initially recruited into the study, and 10 patients aged (mean ± standard deviation) 26.1 ± 11.2 years comprised the final study group. Taste thresholds were significantly elevated on the side ipsilateral to the ear affected by acute otitis media (P < .05). CONCLUSION: Chorda tympani nerve conductance is impaired during the acute stage of acute otitis media. This may have implications in the understanding of peripheral neural properties during acute middle ear inflammatory conditions and on the diagnosis of acute otitis media. [ABSTRACT FROM AUTHOR]

Complications from a prolonged nasogastric tube intubation, though seldom reported, are well described. Herein we describe the first two reported cases of velopharyngeal insufficiency secondary to velopharyngeal scarring and immobility from repetitive nasogastric tube insertions and prolonged use. Differing only in location, the proposed pathophysiologic mechanism of injury is identical to that of the nasogastric tube syndrome, a rare and serious, well described entity consisting of bilateral vocal fold paralysis due to pressure-induced ulceration of the posterior cricoarytenoid musculature.
