To determine the difference in bleeding when extracapsular tonsillectomy with electrocautery is performed on the dominant and nondominant side of the surgeon's hands.Retrospective cohort study.Academic university hospital.Medical record data of patients who were admitted with posttonsillectomy bleeding from January 1, 2000, to July 31, 2017, were reviewed. Included were age, sex, surgical indication, side of posttonsillectomy bleeding, and time of bleeding. Information on the surgeon's dominant hand was also collected. All patients underwent total extracapsular resection with electrocautery.Of 280 patients, 186 met the inclusion criteria, 116 (62.3%) males and 70 (37.7%) females. Ages ranged from 2 to 74 years (mean ± SD, 17 ± 13 years; median, 13 years). In 136 cases (73.1%), bleeding was on the side of the surgeon's nondominant hand (The risk of bleeding following extracapsular tonsillectomy with electrocautery on the side of the surgeon's nondominant hand is significantly higher than on the side of the dominant hand. Thus, additional caution is required when operating on the nondominant side of the oral cavity in extracapsular tonsillectomy using electrocautery. These findings raise questions regarding dexterity as a risk factor for posttonsillectomy bleeding.

STUDY OBJECTIVES: Body position during sleep has been related to breathing in adults with obstructive sleep apnea (OSA). While sleep-disordered breathing is common, little information is available on the relation between sleep position and maternal breathing in pregnancy. We examined associations between the supine position, maternal breathing, and perinatal outcomes. METHODS: Women with a singleton, uncomplicated pregnancy were recruited and underwent an ambulatory overnight sleep study between 33 to 36 weeks using the Watch-PAT device. Their medical records were also reviewed. RESULTS: A total of 148 pregnant women were recruited (mean age: 33 ± 4 years; mean body mass index: 27.6 ± 4.0 kg/m(2)). They spent approximately one-half of their sleeping time in a supine position. The group’s mean apnea-hypopnea index (AHI) was 3.6 events/h in the supine position and 2.9, 2.6, and 2.1 events/h for the prone, right, and left positions, respectively. Median AHI and oxygen desaturation index were higher and SpO(2) nadir was lower in the supine versus nonsupine position (P < .0001, P < .0001, and P = .006, respectively). Peripheral oxygen saturation nadir was associated with the percentage of time spent sleeping in the supine position (P = .02). No correlations were found between supine sleep position and perinatal outcomes. There were no differences in the distributions of body positions between women with and those without OSA. CONCLUSIONS: Women in the third trimester of pregnancy with or without OSA spent large proportions of sleeping time in a supine position. Supine position was associated with more respiratory events and more and deeper oxygen desaturation events. They were not associated with perinatal outcomes.

ObjectiveThe 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.ResultsA 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.

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

Objectives Dysphonia and stridor are not infrequent in the pediatric population. Awake nasolaryngoscopy (ANL) is the primary diagnostic procedure used to evaluate a child with stridor and/or dysphonia. The major limitation of this technique is poor cooperation in children, resulting in inadequate visualization of the larynx. Ultrasound is a widely used noninvasive imaging modality that has yet to be applied to the laryngeal examination. Our goal was to investigate the feasibility and diagnostic potential of laryngeal ultrasound (LUS) in cases of pediatric stridor and/or dysphonia. Methods Prospective blinded cohort study of infants and children 0–16 years of age referred for ANL due to voice disorders and/or stridor. Prior knowledge of the etiology was considered an exclusion criterion. Results LUS concurred with the ANL in the diagnosis of abnormal vs normal larynx in 28/32 children that were recruited. LUS had a sensitivity and specificity of 87% (95% CI: 69%–96%) and 100% (95% CI: 16%–100%) respectively, for diagnosing overall laryngeal disorders in comparison to ANL. LUS also had an area under the receiver operating characteristic (ROC) curve (AUC) of 0.93, (P = 0.04, 95% CI: 0.84–1). Conclusion LUS may be applied as an adjuvant diagnostic tool for ruling in laryngeal pathologies in children including dysphonia and stridor. As further experience is acquired the value of LUS in diagnosis will be better understood.

Importance Peristomal pathologies in tracheostomized children are common and often difficult to treat. They may preclude decannulation even after the initial pathology that required tracheostomy had been resolved. Objective We evaluated the safety and effectiveness of combined direct laryngoscopy and trans-stomal endotracheal surgery in the treatment of pediatric peristomal pathologies. Methods The medical records of all children and adolescents with tracheostomies who were surgically treated for peristomal pathologies by a combined endotracheal and trans-stomal approach between January 2006 and August 2018 were retrospectively reviewed. Pathologies included stenosis, tracheomalacia, granulation tissue, and a combination of pathologies. Patient demographics and clinical details were retrieved. The primary outcome measure was successful decannulation. Secondary outcome measures were intra- and postoperative complications and number of procedures performed. Results In total, 105 subjects aged 6 months to 17 years who underwent combined direct laryngoscopy and trans-stomal surgery were included. Fifty-two (49.5%) of them were successfully decannulated. The specific decannulation rates were 30.3%, 56%, and 59.6% for tracheal stenosis (TS), suprastomal granulation tissue (SSGT), and both, respectively. Trans-stomal microdebrider resection resulted in decannulation rates of 66.7% for TS and 88.8% for SSGT. Intra- and postoperative complications occurred in 4 (12.1%), 1 (4%), and 9 (20.45%) patients with TS, SSGT, and both, respectively. Older age at the time of first operation (p = .03) and tracheal stenosis (p = .02) were significantly associated with decannulation failure. Conclusion Combined direct laryngoscopy and trans-stomal endotracheal surgery can enable decannulation in almost 50% of children with peristomal pathologies, thus obviating open surgery. Multiple procedures may be required, depending upon the type and severity of the pathology. Complications are more common with multiple pathologies.

Endoscopic balloon dilation (EBD) is the mainstay of endoscopic therapy for laryngotracheal stenosis (LTS), although there is no evidence that it achieves better results than traditional rigid laryngeal dilators. Rigid bougie dilators are less expensive and easier to use, and confer the advantage of providing tactile information about the stenosis to the surgeon. We analyzed the outcome of endoscopic rigid bougie dilatation of LTS in a large series of children and compared it to the reported results of EBD in the same setting. All cases of pediatric LTS treated by endoscopic rigid dilatation in a tertiary referral center between 2006 and 2015 were retrospectively studied. They were divided into a primary dilatation group (PDG) and a post-reconstruction dilatation group (PRG). The PDG children had no history of reconstructive airway surgery, and dilatation was the major treatment approach. The PRG children underwent dilatations after airway reconstruction surgery as part of routine postoperative management. A successful primary outcome was defined as improvement of dyspnea and achievement of a functional airway without reconstructive laryngotracheal surgery or need for a tracheostomy at final follow-up. Sixty-two children (68 cases, mean age 5.1 years, range 0.7–17.2) underwent 156 endoscopic rigid dilatations. Successful outcome was achieved in 48 cases (70.6%), 73.0% in the PDG and 67.7% in the PRG. There were no procedure-related adverse events. Endoscopic rigid dilatation is a relatively inexpensive and efficacious tool in endoscopic management of pediatric LTS. Its success rates are in the same range as those of EBD.

Introduction Direct laryngoscopy in children is usually performed with spontaneous ventilation and monitored by pulse oximetry. It is currently unknown if spontaneous ventilation has an effect on cerebral oxygenation. We hypothesized that cerebral oxygenation may be impeded during direct laryngoscopy with spontaneous ventilation in children. Objective Our objective was to determine if children who undergo direct laryngoscopy under general anesthesia with spontaneous breathing experience significant reductions in cerebral oxygen saturation levels, and whether or not these reductions are accompanied by decreases in peripheral oxygen saturation levels. Methods This pilot study included 16 consecutive children who underwent direct laryngoscopy under general anesthesia and spontaneous ventilation. The INVOS™ system, which is currently used to monitor cerebral oxygen saturation levels during neurosurgery and cardiothoracic surgery, consists of a processing unit and 2 sensors that are applied to the patient's forehead. We used it to record cerebral oxygenation levels throughout the procedure. Peripheral pulse oximetry was recorded simultaneously, and the results were compared to the levels recorded by the INVOS™ system. Results Cerebral oxygen saturation levels decreased by more than 20% from baseline in 7/10 children with tracheostomy and in 2/6 children without tracheostomy, while peripheral oxygen saturation levels remained intact in all the children. The mean time from induction of anesthesia to significant decrease in the cerebral oxygenation level (rSO2) was 14 ± 6 min for the tracheostomy group and 14.5 ± 1.5 min for the no tracheostomy group. Conclusions Children who undergo direct laryngoscopy under general anesthesia with spontaneous ventilation may display reductions in brain oxygenation levels that are not detected by standard pulse oximetry, which reflects only peripheral oxygenation levels. Further study is required to explore the possible effect of this phenomenon in children who undergo direct laryngoscopy.

Background Direct laryngoscopy and rigid bronchoscopy are currently performed using 2-dimensional endoscopic systems. Our objective was to determine whether a 3-dimensional endoscopic system can enhance visualization of the surgical field in pediatric direct laryngoscopy and rigid bronchoscopy. Methods A prospective cohort study was conducted. Thirty three children who underwent direct laryngoscopies in a tertiary referral children's hospital were enrolled. Direct laryngoscopy was performed using both 2- and 3-dimensional endoscopic systems, after which the surgeons scored the quality of the images obtained with each system on a scale from 1 (low) to 5 (high). Comparison of the scores obtained with the 2 endoscopic systems was performed. Results The 33 study children (mean age 2.3 years, M:F ratio 1:1.6) underwent 47 direct laryngoscopies. The mean score for visualization of the glottis was 4.8 for the three-dimensional system compared to 4.0 for the two-dimensional system (P = .025), 4.7 vs. 3.8, respectively, (P = .019) for the subglottis, and 4.6 vs. 3.9, respectively (P = .031) for visualization of the proximal trachea. The mean score for visualization of the distal trachea was 3.0 vs. 3.7, respectively (P = .020). In a child with recurrent type 3 laryngotracheal cleft a residual tracheo-esophageal fistula could not be detected using the 2D system, but was immediately detected using the 3D system. Conclusions Visualization of the glottis, subglottis and proximal trachea during direct laryngoscopy using a 3-dimensional endoscopic system was rated by the surgeons as being superior to the conventional 2-dimensional technique. Further outcome studies that will demonstrate the clinical advantage of the 3D technology are highly required. Level of evidence: 2b.

Informed consent is an important part of the surgical process. Based on our clinical experience, we hypothesized that parents providing consent for their children's tonsillectomy do not comprehend all the information that is given to them by the operating surgeon at the time of a conventional consent process.Parents whose children were scheduled for tonsillectomy with or without adenoidectomy and/or tympanostomy tubes insertion were enrolled. Within one hour after the consent process, they were asked to complete a questionnaire designed to collect demographic data and to evaluate how much of the information that was given to them was actually understood.Ninety-seven parents were enrolled between October 2011 and March 2013. The average percentage of correct answers (score) for the 16 multiple-choice questions was 76.3%. The average scores were 84.8% for the native Hebrew-speaking parents and 71.9% for the parents whose first language was other than Hebrew (p 0.01). The average scores were 83.3% for the parents who are healthcare system workers and 74.4% for those parents whose profession is not related to medicine (p 0.05). Fifty parents (51.5%) responded incorrectly to at least one of two questions that we defined as essential: "What would you do if your child starts to bleed from the mouth" and "What kind of food is recommended for your child during the first week after the surgery".The current conventional method of obtaining informed consent for tonsillectomy is inadequate, as reflected by the low level of parental comprehension of essential information. Further studies which will evaluate methods for improving the consent process are highly warranted.

Introduction An accepted screening question for Obstructive Sleep Apnea (OSA) in children is “Does your child snore”. However, this has no correlation to severity. The purpose of this study is to evaluate a simple 2-item questionnaire that reflects the degree of parental concern to predict the severity of Obstructive Sleep Apnea (OSA) in children as measured by Polysomnography (PSG). Methods Prospective analysis of parental concern regarding their children referred for PSG due to suspected OSA. Parents of all study children completed the brief Parental Concern Scale (PCS) questionnaire that we devised and the validated Pediatric Sleep Questionnaire-Sleep-Related Breathing Disorder questionnaire (PSQ-SRBD). The PCS consisted of 1 question on the need for surgery and 1 question on concerns about the child's breathing. Both questionnaires were compared to PSG results. Results Ninety-five children (mean age 4.2 ± 2.5 years, 52% males, mean body mass index z score 0.45 ± 1.8) were recruited. Twenty-three children (24%) had moderate-severe OSA and were referred for adenotonsillectomy. Correlations were found between the need for surgery score and the apnea-hypopnea index (r = 0.22, P = .029), as well as the mean SpO2 levels (r = −0.24, P = .02). The likelihood for the diagnosis of moderate-severe OSA by PSG increased as parental ranking for the need for surgery increased (P = .003). The need for surgery score was the only predictor for moderate-severe OSA (P = .039). Conclusion Querying parents on their perception of their child's need for surgery is a practical, and easy-to-use tool that can help the clinician in prioritizing referral to PSG.

To describe a novel radiographic sign ("halo") and a new classification method of an evolving perisigmoid epidural abscess and present its correlation with intraoperative findings.Retrospective and prospective cohort study in a tertiary academic children's hospital.The retrospective arm (15 children) was conducted between 1998 and 2007 and the prospective arm (11 children) between 2008 and 2013. The computerized tomographic appearance of the perisigmoid region was classified into four groups: Class I, normal; Class II, smooth halo; Class III, nodular halo 4 mm or less in diameter; and Class IV, gross nodular halo more than 4 mm in diameter. Intraoperative findings of the perisigmoid region were compared with the preoperative scan results.The correlation between preoperative imaging and intraoperative findings of the retrospective arm was highly significant (p = 0.007). The correlation between the preoperative imaging studies and intraoperative findings of the prospective arm was also highly significant (p = 0.005). The interobserver agreement for the proposed classification method was high (Cohen kappa score, 0.76; weighted kappa score, 0.84).A novel radiographic sign ("halo") and a new classification method for an evolving perisigmoid epidural abscess in acute mastoiditis are described. A thin and smooth halo sign is not indicative of a true abscess formation. Gross perisigmoid granular changes, however, are highly suggestive of an epidural abscess that warrants surgical intervention.

Objectives Seven years after the introduction of the pneumococcal conjugate vaccines (PCV) in Israel, its effect on the incidence and severity of episodes of acute mastoiditis (AM) remains unclear. The primary objective of this study was to determine the incidence of AM and describe its clinical features in children during the years that followed the introduction of the PCV13 in comparison with the pre-PCV period. Methods Included in this retrospective comparative case series were all pediatric patients diagnosed with AM between Jan. 2007 and Dec. 2015 in one tertiary medical center. The patients were divided into 3 groups: pre-PCV, post-PCV7 (July 2009 through Dec. 2010) and post-PCV13 (Jan. 2011 through Dec. 2015). The patients' medical records were reviewed, and data on age at presentation, gender, presenting signs, bacterial ear cultures, hospitalization course, complications, surgical interventions, inflammatory response and outcome were retrieved and compared between the groups. Comparison was made between the pre-PCV and the post-PCV13 groups. Results 216 children were identified for analysis, 80 children in the pre-PCV period, 31 in the post-PCV7 period and 105 in the post-PCV13 period. Their mean age was 2.6 years. The number of AM cases per 1000 visits at the emergency room decreased by 46% in the post-PCV13 period compared to the pre-PCV period. There was no difference in the rate of AM between the post-PCV7 and post-PCV13 periods. No differences were found in age, gender, hospitalization length, C-reactive protein level, white blood cell count, rate of surgical interventions (mastoidectomy and incision and drainage) and rate of complications between the 3 groups. Conclusion The incidence of AM was lower in the post-PCV13 period compared to the pre-PCV period. The rate of AM complications, however, has not changed, nor has the number of mastoidectomies.

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

OBJECTIVES To characterise the craniofacial structure by cephalometry, especially the skull base and nasopharyngeal space, in children who underwent adenoidectomy and developed persistent velopharyngeal dysfunction (VPD). DESIGN Retrospective study. SETTING Speech and swallowing clinic of a single academic hospital. PARTICIPANTS Thirty-nine children with persistent VPD following adenoidectomy (mean age 8.0±3.6 years) and a control group of 80 healthy children. MAIN OUTCOME MEASURES Cephalometric landmarks were chosen; craniofacial linear and angular dimensions were measured and analysed. RESULTS The linear dimensions of the nasopharyngeal area were shorter in the VPD group, S-Ba (41.6±4.2 mm, P

Objective Evaluate the inter-observer correlation of sleep endoscopy findings in children with persistent obstructive sleep apnea (OSA) with awake office fiber-optic endoscopy. Method Design: retrospective case series; blinded review. Setting: tertiary care children's hospital. Patients: Children with persistent obstructive sleep apnea. Interventions: Both awake and drug induced sleep endoscopy were performed. Endoscopy video recordings were mixed at random on a DVD. Two pediatric otolaryngologists and two pediatric pulmonologists independently scored each recording using an upper airway endoscopy scoring survey. Main outcome measures: reviewers scored the following parameters: each structure's contribution (nose, nasopharynx, lateral pharyngeal walls, tongue base, supraglottis) to the obstruction, the main site in which the obstruction occurs, the severity of OSA (mild, moderate, severe), the level of confidence of endoscopy findings (poor, fair, good). Results When reviewing sleep endoscopy recordings for the upper airway obstruction site, the highest correlation among the four observers was found for the nasopharynx and the supraglottis (Kappa score: 0.6 and 0.5, respectively). Compared to awake endoscopy, sleep endoscopy demonstrated more cases of airway obstruction caused by collapse of lateral pharyngeal walls and base of tongue (McNemar test for symmetry, P value Conclusions Sleep endoscopy is a consistently reliable tool for identifying the site of obstruction in children with persistent OSA. Though anesthetic induced sleep is not a perfect model for real sleep, the technique demonstrably guides further therapy better than awake endoscopy.

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.

To review the current management of acute mastoiditis with critical emphasis on the role of myringotomy.A retrospective chart review.Tertiary-care, university affiliated children's hospital.One hundred and forty-four consecutive children hospitalized for acute mastoiditis between the years 1991 and 2002.All children were treated with parenteral antibiotics (conservative management). Myringotomy was performed at the discretion of the otolaryngologist on-call.Comparing outcomes of children with or without myringotomy regarding hospital stay, complications and the need for surgical interventions.Myringotomy was performed in 34.6% of episodes. The children who underwent myringotomy were found to be significantly younger (22.4 compared to 28.8 months, p=0.028) and had more complications (n=17 vs. n=8, p0.001). Complications overall occurred in 16.3% of episodes. Performing myringotomy had no significant effect on the duration of hospital stay. Children pretreated with antibiotics underwent significantly less myringotomies p=0.027. There were no significant differences between children who underwent myringotomy and those who did not with regard to WBC count, or ESR.These findings suggest that myringotomy may not be required in all cases of acute mastoiditis. Parenteral antibiotics is sufficient in most cases. Criteria for myringotomy may include a younger age. Conservative management resulted in good outcomes in this series.

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.

Cochlear dysplasia is a rare congenital anomaly. However, early detection of this anomaly can prevent serious consequences. We describe three cases of cochlear dysplasia that presented with recurrent meningitis and cerebro-spinal fluid (CSF) leak in children in which early diagnosis prevented further complications.

To evaluate the long-term outcome of atticotomy (AT) surgery for cholesteatoma in children.Case series, retrospective chart review.General otology practice in a teaching hospital.Fifty-three children aged 5 to 16 years old with cholesteatoma limited to the attic and middle ear who underwent AT between the years 1979 to 1994.AT consisting of removal of cholesteatoma confined mainly to the attic. The procedure consists of removal of the lateral attic wall (scutum) and involved ossicles with excision of the cholesteatoma and tympanic membrane grafting with temporalis fascia, leaving a small attical cavity. The mastoid antrum was left intact.Disease recurrence, middle ear status, hearing results, and the need for further surgery.Mean follow up was 5.1 (+/-3.6) years. Eleven (21%) children required completion canal wall down tympanomastoidectomy because of residual disease or recurrence. The mean preoperative speech recognition threshold was 39.4 +/- 13.4 dB. The mean postoperative speech recognition threshold was 34.5 +/- 15.4, an improvement of 6.1 dB compared with the preoperative level. Last follow-up examination revealed a dry ear in all cases but one.In selected cases, AT can be a less invasive option in children with cholesteatoma limited to the attic and middle ear.

OBJECTIVE: To evaluate children with obstructive sleep apnea syndrome (OSAS) for features of attention deficit disorder (ADD) using an objective test of inattention and impulsivity: Test of Variables of Attention (TOVA) and then to determine whether tonsillectomy and adenoidectomy (TA) results in an improvement in TOVA scores. STUDY DESIGN AND SETTING: This study was a prospective interventional comparative trial in a tertiary care children’s hospital. Nineteen children ages 5 to 14 years with OSAS, and otherwise healthy, with a clinical indication for TA. Preoperative and 2 months postoperative OSA-18, CBCL questionnaires, and TOVA scores were evaluated. RESULTS: The preoperative TOVA scores were in the abnormal range in 12/19 (63%) of the children. The mean preoperative TOVA score was 2.9 ( 3.1). The mean postoperative TOVA score was 0.4 (2.8). The improvement in the TOVA scores was significant (P < 0.0001, t-test). CONCLUSION: This preliminary data suggests that treatment of OSAS with TA results in significant improvement in objective parameters of inattention and impulsivity. SIGNIFICANCE: These findings may be important in understanding the impact of OSAS and therapeutic interventions on behavioral problems in children. (Otolaryngol Head Neck Surg 2004;131:367-71.) S leep-disordered breathing (SDB) is a relatively common condition in otherwise healthy children. It includes a continuum of pathologies, with obstructive sleep apnea (OSA) considered to be the more severe form. The prevalence of OSA is estimated to be 1% to 2% of all children. 1 The underlying pathophysiology of OSA in children is thought to be a dynamic process caused by upper airway narrowing and abnormal upper airway neuromotor tone resulting in airway collapse during sleep. OSA in children is predominately associated with adenotonsillar hypertrophy, but can also be associated with other upper airway pathology such as a small mouth or pharynx, decreased upper airway tone

Summary Objective: Adenotonsillar hypertrophy (ATH) is the leading cause for obstructive sleep apnea syndrome (OSAS) in children. The peak age for adenoid and tonsillar hypertrophy and related OSAS is 3/6 years. It has been suggested that OSAS due to ATH is extremely rare in infants. The purpose of the present study was to delineate OSAS due to ATH in infants. Methods: Twenty-nine consecutive infants B/18 months of age who underwent polysomnography (PSG) and were diagnosed with OSAS due to ATH were studied. A pediatric sleep questionnaire was completed by parents of all infants. Information regarding demographic variables, referring physician specialty, assessment of infant’s development and recurrence of symptoms post treatment was collected. Pre and post surgery body weight and developmental assessment by parents were evaluated. Results: The mean age of adenotonsillectomy was 12.39 /3.9 months with the mean duration of symptoms ranging 6.29 /3.0 months. 24% of the infants were born preterm. Snoring was the most common finding and appeared in all infants. Other symptoms were sleep apnea (72%), frequent movements during sleep (69%), mouth breathing (62%) and recurrent awakenings (38%). During the preoperative period, mean body weight decreased from the 67th9 /25 percentile to the 42nd9 / 32 percentile (P B/0.00001). 14/29 (48%) of the infants dropped two or more major percentiles before treatment. A significant weight gain to the 59th9 /31 percentile was observed post surgery (P B/0.0001). 5/29 (17%) infants were considered by their parents as having a developmental delay preoperatively, which resolved in 3/5 (60%) post treatment. Clinical symptoms resolved or improved significantly after surgery. Recurrence of symptoms was documented in 6/23 (26%) of infants. Conclusions: Infantile OSAS due to hypertrophic adenoids and tonsils does occur in infants. Unique characteristics for this age group include: male predominance, high incidence of preterm infants, failure to gain weight and high recurrence rate after surgery. Otolaryngologists and pediatricians should be aware to the existence of the ‘‘early OSAS’’ in small infants.

Multilevel surgery for obstructive sleep apnea syndrome (OSA) may improve success. This study's goal is to prospectively evaluate the feasibility and short-term subjective effectiveness of a new tongue-suspension technique.A multicenter nonrandomized open enrollment trial used the Repose device to treat tongue obstruction in 39 snoring and OSA patients. Outcomes include 1- and 2-month subjective reports of general health, snoring, and sleep.Twenty-three patients completed 1 month and 19 completed 2 months of follow-up. In OSA patients, activity level, energy/fatigue, and sleepiness improved. Two-month outcomes were less (activity level, energy/fatigue, and sleepiness). Fewer changes were observed in snorers than in OSA patients. There were 6 complications (18%), including sialadenitis (4), gastrointestinal bleeding (1), and dehydration (1) after the procedure.A pharyngeal suspension suture changes subjective outcomes. Improvement is incomplete. The procedure is nonexcisional, but significant complications may occur. Further evaluation is required to demonstrate effectiveness.

The Repose system is a new minimally invasive technique for tongue-base suspension in the treatment of sleep-disordered breathing caused by tongue-base collapse. It involves the insertion of a titanium miniscrew with attached suture into the anterior intraoral mandible and passing the suture through the tongue base. The procedure was performed in 16 patients with sleep-disordered breathing. Fourteen patients reported an improvement in daytime sleepiness, and their bed partners reported an improvement in snoring. The mean respiratory distress index before surgery was 35. Two months after surgery, the mean respiratory distress index was 17, an improvement of 51.4% (P = 0.001, 2-tailed t test). These preliminary results show the initial efficacy and safety of this new surgical procedure.

Lasers using different wavelengths and delivery systems have been used to reduce the inferior turbinate mass when hypertrophic inferior turbinates obstruct the nasal airway. Different laser systems produce different laser-tissue interactions. This study presents a comparison between three laser systems: CO2, Nd:YAG, and Diode lasers for inferior turbinate reduction surgery, all performed under endoscopic control. A total of 46 patients were randomized into three treatment groups and followed for more than 1 year. Subjective and objective data were collected. Subjective impressions of improved nasal airway was achieved in 41% (Diode), 47% (Nd: YAG) and 57% (CO2) and was not statistically significant. There was more postoperative bleeding in the CO2 laser group, with 3 patients requiring tamponade. The CO2 laser procedure also took longer to perform. These results failed to show a significant difference between the different lasers for inferior turbinate reduction. Overall, the results were not impressive.

The variability of the normal velopharyngeal (VP) closure mechanism was studied by investigating VP anatomy in relation to its closure mechanism in 60 patients. The axial configuration of the VP isthmus, as observed in axial CT scans at rest, was found to be correlated with VP function in terms of its closure patterns in speech as observed by nasendoscopy. A flat VP isthmus was found to be closed mainly in the anteroposterior direction, forming the coronal closure pattern. A deep VP isthmus is closed by movement of the velum and medial movement of the lateral pharyngeal walls, forming the circular closure pattern. A flat VP isthmus occurs when the hamuli are posteriorly located and the muscular slings, therefore, open more posteriorly. We conclude that posterior insertion of the velar muscles on to the skull base results in a flatter, larger VP axial configuration, whereas an anterior insertion results in a VP axial configuration that is deeper and less flat. A flat VP isthmus contracts mainly in an anteroposterior direction, exhibiting a coronal closure pattern, while a deep or round VP isthmus contracts centripetally, exhibiting a circular closure pattern. Variability of the VP valving mechanism is of anatomic and not of functional origin.

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.

A 7-months-old female presented with coughing spells while feeding. Flexible laryngoscopy revealed a round bluish mass, emanating from the postcricoid area when the child cried or strained and disappeared when she relaxed. She was treated with systemic steroids for a month and was doing well. There was no change in the lesion. On examination at age 18 months the lesion disappeared. In a review of the literature, the authors found 6 articles describing 19 children with postcricoid vascular lesions. Seven children did not have significant related problems and did well without any treatment. Eight cases had significant co-morbidity. Treatment for symptomatic children included systemic or intralesion steroids, laser ablation and open resection. Postcricoid vascular lesion is a rare entity with a typical appearance. The recommended workup includes flexible laryngoscopy and videofluoroscopy. There are several treatment options for symptomatic children.

Post-traumatic cerebrospinal fluid leak from the anterior cranial fossa in children may be isolated or combined with severe facial and calvarial injury. Untreated leak may result with meningitis, hydrocephalus, and abnormal neurocognitive development. We present nine children, ages 4–16 years, with complicated craniofacial injury treated by a combined subcranial and intracranial approach. A continuous lumbar drainage was kept for several days, and prophylactic antibiotics and anti-convulsive medications were routinely given. A multidisciplinary approach including discussion before surgery about other surgical options (endoscopic extracranial and intracranial alone) were performed. None of the operated children had episodes of meningitis/leak after the combined approach, suggesting that appropriate sealing of the base of the skull has been achieved. There was no mortality, and the long-term follow-up showed good developmental and cosmetic results. Most of the children had significant brain contusions prior to surgery; however, these did not progress as minimal retraction was enabled by the extensive subcranial and intracranial approach. Child’s age, anatomy of the bone, extent of cranial injury, and clinical parameters should be seriously considered when choosing the technical methods as for sealing base of skull and reconstruction of facial/cranial bones. Young age does not seem to be a contraindication to the combined approach, thus, we recommend considering it in extensive base of skull fractures when concomitant cranial, maxillofacial, and orbital fractures coexist, as alternative options may not suffice in these cases.

Objective Eustachian tube dysfunction and sleep-disordered breathing (SDB) share common pathophysiologic mechanisms. Our objective was to investigate whether children referred for isolated TTI (tympanostomy tube insertion) are at increased risk for snoring and upper airway procedures. Methods Telephone interviews to parents of children who underwent isolated TTI and to age- and gender-matched controls were conducted. Results Four hundred fifty-seven children were included in the study; 352 had isolated TTI (study group) and 105 children were controls. Twenty-two percent of children in the study group were reported to snore compared with 7.6% in the controls ( p =0.001). Eighteen percent of children in the study group were reported to have undergone adenotonsillectomy compared with 4.8% in the controls ( p =0.0005). Future SDB, i.e., either snoring or adenotonsillectomy following TTI, was found in 34% of children in the study group compared with 11% in the controls ( p =0.0004). Children who underwent isolated TTI were at increased risk for future snoring (OR=3.4, CI: 1.6–7.2) and future adenotonsillectomy (OR=4.4, CI: 1.7–11.2). Conclusions Children who undergo isolated TTI are at increased risk for snoring and for adenotonsillectomy. We suggest that these children be followed for symptoms of SDB on a scheduled basis to allow for early diagnosis and intervention.

The cat eye syndrome is a congenital malformation usually associated with anal atresia, ocular coloboma, downward slanting eyes, microphthalmia, hypertelorism, strabismus, preauricular tags or fistulas, congenital heart defect particularly septal defect, urinary tract abnormalities, skeletal anomalies and frequently mental and physical retardation. A small supernumerary chromosome (smaller than chromosome 21) is present, frequently has 2 centromeres, is bisatellited and represents an inv dup 22 (q11). A two years old female presented to our department with an association of cat eye syndrome with preauricular tags and a first branchial arch anomaly. This article discusses the surgical management and the association between the cat eye syndrome and first branchial cleft anomaly.

Fiberoptic flexible laryngoscopy (FFL) is the diagnostic procedure of choice in patients with laryngomalacia. Two techniques can be applied, either when the infant is awake or using anesthesia/sedation. The choice of technique may effect the diagnosis.To compare the two techniques for diagnosing laryngomalacia.A total of 42 infants who underwent awake fiberoptic laryngoscopy for congenital stridor, in whom either laryngomalacia was diagnosed or no cause for stridor was found, underwent a repeat laryngoscopy using anesthesia/sedation. The 84 video recordings of the supraglottic portions were copied onto a videotape along with 25 recordings of normal upper airways without stridor and 31 duplicate cases with stridor. A total of 140 recordings was mixed at random on a videotape. Sound was not included.Three investigators (Y.S., J.B.A., and A.D.) independently scored each recording using a laryngomalacia scoring system (scoring range, 0 to 8).A threshold score of 2 was the optimal cutoff point for discriminating laryngomalacia from normal condition. The awake technique (WT) missed three cases of laryngomalacia and overdiagnosed one healthy control subject. The anesthesia technique was superior with a sensitivity of 100%, a specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 100% compared with 93%, 92%, 97%, and 79%, respectively, for the WT.The diagnosis of laryngomalacia with FFL is more accurate using anesthesia/sedation. The WT may be appropriate for screening or for patients with mild cases having a characteristic presentation.

Summary We report a rare case of acute otitis media (AOM) complicated by arterial brain infarction, meningitis and orbital cellulitis. Computed tomography (CT) initially showed suspected epidural abscess, coalescent mastoiditis, and orbital cellulitis. Further clinical deterioration occurred following mastoidectomy and evacuation of the abscess. Magnetic resonance imaging (MRI) revealed subacute brain infarction and an extra-axial brainstem abscess. Revision of the initial CT revealed subtle signs suggestive of arterial brain infarction. Although CT with contrast is the standard of care for suspected AOM complications, MRI should be considered as an adjunct when CT is not definitive and neurological signs are present.

To compare the effect of preoperative high-dose systemic corticosteroids on the radiographic and endoscopic appearance of allergic fungal rhinosinusitis (AFRS) and chronic rhinosinusitis with nasal polyposis (CRSwNP).Eight AFRS and 10 CRSwNP patients underwent computed tomographic (CT) scans and then received preoperative 1 mg/kg prednisone for 10 days. CT scans were repeated 1 day before surgery and compared with pretreatment scans (Lund-MacKay radiologic scoring system). The endoscopic appearance was recorded intraoperatively.The score dropped from 16 (66.4%) to 4.75 in the AFRS group and from 18.4 (23%) to 14.1 in the CRSwNP group (P=0.0064). Intraoperatively, most sinus mucosal surfaces appeared normal in the AFRS patients but were markedly edematous in the CRSwNP patients.Radiographic response of AFRS to systemic corticosteroids is significantly greater compared with CRSwNP. This finding is supported by endoscopic observation.

Background. This study aimed to examine the sur- gical, oncologic, and developmental results of infants and chil- dren undergoing extirpation of skull base tumors. Methods. Sixty-seven children aged 0.5 to 18 years (mean, 11 years) who were operated on during a 6-year period made up the study cohort. Eighteen cases (27%) involved malig- nant tumors, and 49 (73%) involved benign tumors. The most common benign tumors were craniopharyngioma (n = 10) and juvenile nasopharyngeal angiofibroma (n = 8). The most common malignant tumor was sarcoma (n = 5). Thirty-six tumors (55%) involved the anterior skull base, and the rest involved the lateral (n = 24) and posterior (n = 7) skull base. Subcranial, transfacial, and subfrontal approaches were used for extirpation of anterior skull base tumors. Voluminous or malignant tumors were excised by use of combined approaches (subcranial-transfacial, subcranial-degloving, or pterional-degloving). Twenty-two children underwent adjuvant therapy (chemotherapy, radiation, or both). Postoperative follow- up was 3 to 60 months. Results. No severe postoperative complications (ie, menin- gitis, cerebrospinal fluid leak, tension pneumocephalus) and no perioperative mortality occurred. Two and a half years later, 54 of the children (80%) are alive and well. Five children, two with optic glioma and one each with squamous cell carcinoma, ependymoma, and germinoma, have died of their disease. The subcranial approach had no cosmetic impact on the craniofacial development of the patients. Conclusion. The extirpation of skull base tumors by use of conventional surgical techniques is feasible and safe among infants and children. The complication and mortality rates are lower than those in adults. The long-term cosmetic effect of the subcranial approach is negligible. A 2005 Wiley Periodicals, Inc. Head Neck 27: 682 - 689, 2005

Objective Chronic isolated frontal sinusitis occurs infrequently. In this condition, most of the ethmoid cells are well aerated and the frontal sinus is involved secondary to anatomical obstruction or inflammatory changes confined to the frontal recess. The purpose of this study was to evaluate a targeted endoscopic technique where standard anterior ethmoidectomy is unnecessary in the treatment of chronic isolated frontal sinusitis. Study design and setting This retrospective study was conducted in a large university-affiliated hospital and included 11 patients with chronic isolated frontal sinusitis who underwent endoscopic sinus surgery limited to the frontal sinus outflow. The ethmoid bulla was untouched in all cases. Follow-up continued for 19 to 40 months (mean 28.6 months). Results Frontal sinus outflow patency was verified in 9 patients (81.8%). Nine patients, including one with an apparent nonpatent frontal ostium, reported improvement. Two patients—one of whom had a patent frontal ostium—reported no improvement. There were no complications. Conclusion Chronic isolated frontal sinusitis can be effectively treated in selected cases by a targeted endoscopic procedure, limited to reestablishment of frontal sinus outflow. EBM rating: C-4

Summary Objective: Otomicroscopic examination with suctioning of ears or other procedures is frequently uncomfortable especially for children. Anxiety and pain with lack of cooperation may result in trauma to the ear, incompletion of the examination, delayed diagnosis and treatment and need for completion of the examination under general anesthesia. The purpose of this study was to evaluate the efficacy and safety of utilizing nitrous oxide–oxygen inhalation for sedation and analgesia in otologic examination and minor surgical procedures performed on the uncooperative child at the outpatient clinic. Methods: In a prospective pilot case series study conducted at the Pediatric Otolaryngology outpatient clinic of a tertiary medical center, nitrous oxide–oxygen inhalation was administered by the examining otolaryngologist and the assisting nurse. The study group included children over 2 years old, for which an accurate diagnosis of ear pathology could not be made or a minor surgical procedure could not be tolerated because of anxiety and lack of cooperation. Results: Completion of the indicated procedure was successful in 21 of 24 patients (88%). Full cooperation, where no restraint was necessary was achieved in 20 of 24 patients (83%). The mean rank pain scores, evaluated separately by the patient, parent and staff, were in the mild pain range using a 0–10 coding for Faces Pain Rating Scale. The mean procedure time was 8.9 min. An adverse reaction, vomiting, occurred in one patient. Twenty-one of 24 parents stated that they would repeat the procedure if necessary. Conclusion: This pilot study shows the potential usefulness of nitrous oxide–oxygen inhalation administered by an otolaryngologist in the outpatient clinic. Alleviation of pain and anxiety and avoiding the need for physical restraint is an important goal that can be achieved with this form of sedation.

A 9 month old girl at the emergency room appeared with an acute onset of restlessness, drooling and suspected foreign body ingestion. An X-Ray revealed an open safety pin in the child's upper aero-digestive tract. The source of the safety pin was a "Hamsah" good luck charm that was attached to her bed. Open safety pins in the aero-digestive tract are difficult to manage and great care must be taken during removal to prevent further injury. Parents should be counseled regarding the presence of safety pins in the child's surroundings in order to prevent such hazards.

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.

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.

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.

In this study we sought to define the histologic changes produced by laser treatment of inferior turbinates.Eight inferior turbinates with prior laser treatment (mean, 26.8 months) were analyzed by light microscopy after turbinectomy for relief of refractory nasal obstruction. Histologic findings were compared with those of a group of 8 hypertrophic inferior turbinates that had no previous laser surgery.Laser-treated areas of the inferior turbinates demonstrated a histologically bland appearance, with marked diminution of seromucinous glands and relative preponderance of connective tissue matrix. Prominence of venous sinusoids was also significantly reduced in the laser-treated areas. Surface epithelium including goblet cells was reconstituted over the areas of laser application.Clinical laser surgery of the inferior turbinate produces striking long-term histologic changes.The data suggest a differential response of turbinate histologic components to application of laser energy, with the glandular component being particularly sensitive. Further correlative study is needed to clarify the clinical significance of laser-induced histologic changes in inferior turbinates.

We suggest that using the sonographic examination as an integral part of the work-up may save the physician and the patient from an unpleasant and uninformative examination, and avid EUA or unnecessary surgery. The type or sonographic examination should be determined by what is known, the equipment available, and the age and past history of the patient. In our institution the transabdominal approach is the choice for any nonsexually active female and the transvaginal approach is the procedure of choice for those females who are emotionally mature and sexually active. This review is addressed to the clinicians taking care of the pediatric and adolescent population. We wish to stress the importance of the sonographic evaluation as an immediate tool for the evaluation of suspected pelvic pathology, gender identity, and sexual-development disorders. We find it convenient and accurate, and feel that in children and young women with such pelvic complaints, it should be considered an important step in the diagnostic process.

Purpose: Suspected impaction of esophageal foreign bodies may at times pose a diagnostic problem as to the decision to perform esophagoscopy. It is not unusual to perform a rigid esophagoscopy following a diagnostic work-up for an impacted foreign body and not to find one. This study attempts to delineate the clinical situations where negative esophagoscopies are more likely to occur. Materials and Methods: In a retrospective analysis of 98 rigid esophagoscopies performed for suspected foreign bodies in our department, an attempt was made to delineate the clinical and radiologic findings characteristic of the patients who had no foreign body at esophagoscopy compared with the patients in whom a foreign body was found. Results: Negative esophagoscopies were associated with suspected bone (mostly fish) impaction in 20 of the 22 negative esophagoscopies. Other parameters associated with negative findings were prolonged duration of symptoms and a positive finding at the physical examination. In suspected bone impaction, barium studies and neck x-rays were not helpful in determining the presence of a foreign body. Conclusion: Clinical history is the main indicator in the decision to perform esophagoscopy for suspected foreign bodies.
