Objective
To determine if adeno-tonsillectomy (T&A) in children with Down syndrome (DS) improves breathing, measured by apnea hypopnea index (AHI), rapid eye movement AHI (REM-AHI) and the lowest oxygen desaturation (SaO2), and sleep disruption, measured by arousal index (ArI) and time spent in stages 1-4 and rapid eye movement (REM) sleep and compare these results with a group of non-DS children with obstructive sleep apnea (OSA).Study design
Retrospective chart review at pediatric sleep center.Patients
Eleven DS and nine non-DS children underwent pre- and post-T&A polysomnography between 1997 and 2005.Outcome measures
Pre- and post-T&A polysomnography parameters were compared using paired t-test and independent samples test.Results
Mean age in DS group was 101 months and non-DS group was 80 months (64% males in DS and 88% in non-DS group). The average BMI was 29.8 and 27.6 for DS and non-DS group. The total AHI showed significant improvement after T&A but this was not as marked as the non-DS group. REM-AHI and lowest SaO2 did not show significant change in the DS children. The non-DS group showed significant improvement in all respiratory parameters. Both groups showed mild improvement in sleep parameters. With the modest overall improvement, 27% of the DS children required no further treatment. However, 73% required CPAP, BiPAP or oxygen for persistent OSA.Conclusion
This study supports the fact that T&A in DS children improves some parameters of OSA, however not as markedly as in non-DS children. 相似文献2.

Introduction
Tympanometry is currently the most frequently used tool for assessing the status of the middle ear, commonly assessed using a single 226 Hz tone. However, the use of the Acoustic Immittance Measures with a wideband stimulus is a promising high-resolution evaluation, especially in individuals known to have middle ear alterations, such as Down syndrome patients.Objective
The aim of this study was to analyze the acoustic absorbance measurements in children with Down syndrome.Methods
Cross-sectional study, approved by the institution's ethics committee. Data were collected from 30 children, with a mean age of 8.4 years, 15 with Down syndrome (DS-study group) and 15 children with typical development and no hearing complaints (control group). Energy absorbance was measured at frequencies of 226–8000 Hz at ambient pressure and at peak pressure as a function of frequency using TITAN equipment. Statistical analysis was performed using the established level of statistical significance of 5%.Results
With the 226 Hz probe tone, 30 ears of the control group and 22 of the study group exhibited Type A tympanograms, whereas Type B was observed in eight children in the study group. The mean acoustic absorbance ratio of the study group was lower than that of the control group at frequencies centered at 2520 Hz (p = 0.008) for those with normal tympanometry results, and 226–4000 Hz (p < 0.03) for those with a Type B tympanometry curve.Conclusion
The low energy absorption in the presence of normal tympanograms in children with Down syndrome may suggest middle ear abnormalities. 相似文献3.

Background
For children with Down syndrome, the incidence of hearing loss may be as high as 78% [1], therefore the American Academy of Pediatrics recommends regular screening for the presence of hearing abnormalities. Tympanometry is used as an indication of middle ear pathology. In our experience, Down's patients’ tympanograms do not always correlate with otoscopic findings. Down's patients have joint laxity, small ear canals, anterior tympanic membrane orientation and softer tissue composition, all factors thought to affect tympanogram results in infants. Because the use of the 1000 Hz tympanometry is widely recognized as standard procedure in the evaluation of infants aged 0–6 months, we propose it may have greater reliability in testing patients with Down syndrome.Objective
Compare the results of visual inspection of the tympanic membrane by a Pediatric Otolaryngologist to the results of tympanometry at traditional probe tone (226 Hz) and at the infant probe tone (1000 Hz).Methods
Institutional Review Board – approved prospective study of 26 subject-ears in patients with Down syndrome aged 6 months–18 years but recent stable middle ear/Eustachian tube function using physical examination and tympanometric probe tones at 226 Hz and 1000 Hz.Subject-ears were examined with record of “clear of effusion,” showed the presence of “fluid,” or were to be “excluded.” Blinded to ear exam results, tympanometry was then completed with record of which Jerger classification tympanogram was found at each frequency.Results
Although the sensitivity of each test was 1, the specificity of the 1000 Hz tympanometry (100%) in this study was markedly improved compared to the specificity of the 226 Hz tympanometry (71%) (p = 0.016).Conclusions
This pilot study demonstrated evidence that tympanometry in children with Down syndrome may be more reliable at 1000 Hz than at 226 Hz in detecting the presence of middle ear effusion beyond infancy. Use of the 1000 Hz probe tone yielded fewer false positives for disease (type B tympanograms in the setting of absent middle ear disease). Further studies of a larger patient population are needed to corroborate these results. 相似文献4.

Introduction: Although, the association between Down syndrome (DS) and conductive hearing loss is well recognized, the fact that a small proportion of these children may have a severe to profound sensorineural hearing loss that could benefit from cochlear implantation (CI) is less well understood. The management of significant co-morbidities in children with DS can delay initial diagnosis of hearing impairment and assessment of suitability for CI can likewise be challenging, due to difficulties conditioning to behavioural hearing tests.Methods: We performed a retrospective case note review of three children with DS referred to the Manchester Cochlear Implant Programme.Results: Three illustrative cases are described including CI in a 4 years old. Using conventional outcome measurement instruments, the outcome could be considered to be suboptimal with a Categories of Auditory Performance score of 4 at 6 months post-op and at last follow up. In part, this is likely to reflect the delay in implantation, but the role of cognitive impairment must be considered. The cases described emphasize the importance of comprehensive radiological and audiological assessment in children with DS being considered for CI.Conclusion: The influence of cognitive impairment upon outcome of CI must be taken into account, but should not be considered a contra-indication to implantation in children with DS. Benefit that might be considered limited when quantified using existing general outcome measurement instruments, may have a significant impact upon psychosocial development and quality of life in children with significant cognitive impairment, or other additional needs. 相似文献

Ear,nose and throat disorders in children with Down syndrome 总被引:1,自引:0,他引:1
OBJECTIVE: To document the reasons for which children with Down syndrome were referred to a pediatric otolaryngology practice, the underlying causes for these referrals, and the complications of routine surgical therapy. STUDY DESIGN: The study is a retrospective review of children referred to the Pediatric Otolaryngology Clinic at the University of New Mexico Health Sciences Center (Albuquerque, NM) during a period of 2.5 years. METHODS: Data were collected on 55 parameters related to ethnicity, demographics, diagnosis, surgical therapy, complications, and systemic comorbid conditions. RESULTS: The ethnicity of the study population was predominantly Hispanic or Latino (62%). The majority of children (76%) were referred for upper airway obstruction. Obstructive sleep apnea and laryngomalacia were the most common disorders in these children. An otological disorder was diagnosed in 70% of the children. Complications occurred after 27% of procedures for insertion of pressure equalization (PE) tubes to treat recurrent otitis media. Systemic comorbid conditions were present in 93% of the children, and the most common was gastroesophageal reflux disease. CONCLUSIONS: Obstructive sleep apnea and laryngomalacia were the most common reasons for referral of children with Down syndrome. Routine surgical procedures that required general anesthesia caused complications that are not common in other children. Treatment for systemic comorbid conditions should be considered as a component of therapy for otolaryngological disorders in children with Down syndrome. 相似文献

OBJECTIVE: There is well-documented evidence in the literature concerning a high prevalence of deafness in children with Down syndrome (DS). The aim of this study was to examine the extent of hearing impairment and address the rehabilitation needs of a Chinese population with DS who were either in special schools or integrated into mainstream schools. METHODS: This study screened 92 children with DS at their own schools and 11 were reassessed in the University of Hong Kong Hearing Centre. Hearing status of the children with DS was analyzed on the basis of their screening and reassessment results for tympanometric, transient evoked otoacoustic emission (TEOAE) and pure tone audiometric examinations. RESULTS: A high point prevalence of hearing impairment (78% by ears or 90% by participants) in a Chinese school-aged sample of children with DS was noted. The most common degree of loss was mild to moderate. No significant gender difference, age effect or ear asymmetry was found for tympanometric failure or absence of TEOAE. An unfavorable mean speech intelligibility index score (0.2) was found for this group of children. CONCLUSIONS: Sound field amplification and suitable acoustic modifications to classrooms were recommended for Chinese children with DS in Hong Kong to improve their listening and learning environment. The point prevalence of hearing impairment in older children with DS in this study was in contrast to a previous local study on a younger age group. Further effort is needed to determine the role of possible aging effects on the type and prevalence of hearing impairment in populations with DS. 相似文献

OBJECTIVES: To evaluate complication rates and outcomes of children with Down syndrome fitted with a Bone Anchored Hearing Aid (Baha). To evaluate whether the Bone Anchored Hearing Aid is a successful form of aural rehabilitation in children with Down syndrome from a patients' perspective. STUDY DESIGN: Retrospective case analysis and postal questionnaire study. SETTING: The Birmingham Children's Hospital, UK. METHODS: A total of 15 children were fitted with a Baha between February 1992 and February 2007. The age range was 2-15 years. A postal questionnaire was sent to each family. The Glasgow Children's Benefit Inventory (GCBI) was used in this study. OUTCOME MEASURES: Implantation results, skin reactions and other complications were recorded. Quality of life after receiving a Baha was assessed with the GCBI. RESULTS: All 15 patients are using their Baha 7 days a week for more than 8h a day after a follow-up of 14 months with continuing audiological benefit. No fixtures were lost, and skin problems were encountered in 3 (20%). Regarding quality of life, all 15 patients had improved social and physical functioning as a result of better hearing. CONCLUSIONS: Baha has an important role in the overall management of individuals with Down syndrome after conventional hearing aids and/or ventilation tubes have been considered or already failed. This study has shown a 20% rate of soft tissue reaction and there were no fixture losses in this group. No significant increase in complication rates was identified in children with Down syndrome. Finally, there was a significantly improved quality of life in children with Down syndrome after receiving their Baha. There was a high patient/carer satisfaction with Baha. Two of our series had bilateral two stage fixture procedures without any complications. More consideration should be given to bilateral bone anchored hearing aids in this group. 相似文献

Objectives
Tympanostomy tubes are commonly used for treatment of chronic otitis media with effusion (COME) or recurrent acute otitis media (RAOM) in patients with Down syndrome, but hearing outcomes in this population have been mixed, and complications appear to be common. We aim to characterize outcomes and complications associated with tympanostomy tube placement in this population.Methods
Retrospective review. All patients with Down syndrome presenting to a tertiary academic pediatric otolaryngology practice over a ten year period from 2002 to 2012 who received tympanostomy tubes for COME, RAOM, or hearing loss were reviewed.Results
Long term follow up data was obtained in 102 patients, with average follow up 4.7 years. COME was the primary indication for tube placement in 100/102 (98%). Less than half of these patients (44%) initially failed their newborn hearing screen. Post operative hearing was found to be normal or near normal for the better hearing ear in 85/99 (85.9%), and normal to near normal in bilateral ears in 71/99 (71%). A majority (63.7%) of patients required two or more sets of tubes during the follow up period. Long term complications were common and were significantly increased if the patient required three or more sets of tubes, including chronic perforation (36.6% vs 8.2%, p < 0.001), atelectasis (29.3% vs 1.6%, p < 0.0001), and cholesteatoma (14.6% vs 0%, p = 0.003).Conclusions
COME is a frequent problem in Down syndrome, and the majority of patients will require two or more sets of tubes during their childhood and achieve normal postoperative hearing. Long term complications of otitis media appear to be more common in this population and appear to correlate with increasing number of tubes placed. More investigation is required to determine optimal treatment strategies for COME in patients with Down syndrome. 相似文献11.

OBJECTIVES/HYPOTHESIS: Middle and external ear anomalies are well recognized in Down syndrome (DS, trisomy 21). Inner ear anomalies are much less frequently described. This study reviews inner ear morphology on imaging to determine the prevalence of cochlear and vestibular anomalies in children with DS. STUDY DESIGN: The authors conducted a retrospective review of imaging features of (DS) inner ear structures. METHODS: Fifty-nine sequential patients with DS with imaging of the inner ear were identified by a radiology report text search program. Quantitative biometric assessment of the inner ear was performed on patients with high-resolution computed tomography or magnetic resonance images of the petrous bone. Petrous imaging was performed for evaluation of inflammatory disease or hearing loss. Spinal imaging, which included petrous views, was performed in most cases to exclude C1 to 2 dislocation, a potential complication of DS. Measurements were compared with normative data. RESULTS: Inner ear dysplasia is much more common in DS than previously reported. Inner ear structures are universally hypoplastic. Vestibular malformations are particularly common and a small bony island of the lateral semicircular canal (<3 mm in diameter) appears highly typical. Additional findings in some patients were persistent lateral semicircular anlage with fusion of the lateral semicircular canal and vestibule into a single cavity, vestibular aqueduct and endolymphatic sac fossa enlargement, cochlear nerve canal hypoplasia, and stenosis or duplication of the internal auditory canal. Stenosis of the external meatus, poor mastoid pneumatization, middle ear and mastoid opacification, and cholesteatoma were common, as expected. 相似文献

Purpose
Ultrasonography is a well-established modality for visualization of head and neck anatomy. Using ultrasound to detect vocal fold mobility has been described before, but no study has evaluated factors affecting the exam reliability. The aim of the study is to determine anatomic factors influencing the reliability of ultrasound to detect vocal fold motion.Methods and materialsPatients underwent ultrasound evaluation and flexible laryngoscopy to assess vocal fold motion from August 2015 to March 2016. Length, accuracy, and clarity of ultrasound examination were assessed, compared to flexible laryngoscopy. For patients with prior neck CT scan imaging, laryngeal anatomy was independently assessed by a blinded neuroradiologist.Results
A total of 23 patients, 21 with bilateral vocal fold motion and two with unilateral paralysis, were enrolled. Vocal folds were visible in 19 patients (82%). Eight patients (42%) had good/excellent view and 11 patients (58%) had fair/difficult view. The ultrasound correctly detected absent movement of the vocal fold in the two patients with unilateral paralysis. A total of 19 patients had CT scans, and a linear correlation (r2?=?0.65) was noted between the anterior thyroid cartilage angle measured on CT and the grade of view on ultrasound.Conclusion
Ultrasound was able to detect vocal fold motion in 82% of randomly screened patients. Ease of detection of vocal fold motion correlated with the anterior thyroid angle. Further studies are warranted to investigate the reproducibility of our results and how this might impact use of ultrasound for detection of vocal fold motion in the operative setting. 相似文献13.

Objective
The purpose of the study was to investigate the effects of age and gender on adolescents’ vocal tract dimensional development with acoustic reflection technology (ART).Methods
A total of ninety-five male and female adolescents aged between 10 and 18 divided into three age groups were tested with acoustic reflection technology (ART) and acoustic program to secure their vocal tract dimensional parameters and the vowel formant frequencies.Results
Significant age and gender effects were found not only in vocal tract length, but also segmental volumetric measurements, as well as the vowel formant frequencies.Conclusions
The findings of this study have provided insights on the developmental trend of adolescents’ vocal tracts. The study has also offered a preliminary anatomical database of adolescents’ vocal tract dimensional growth for otolaryngologists, clinical anatomists, speech therapists and other health professionals of swallowing, respiration and communicative disorders. 相似文献14.
Cine magnetic resonance imaging: evaluation of persistent airway obstruction after tonsil and adenoidectomy in children with Down syndrome 总被引:5,自引:0,他引:5
OBJECTIVE/HYPOTHESIS: Although usually successful, not all obstructive sleep apnea is cured by removal of the tonsils and adenoids (T&A). This is particularly true in children with Down syndrome and craniofacial anomalies. This is because of the multiple levels of obstruction in their airways, with obstruction present not only at the level of the tonsils and adenoids but also from base of tongue obstruction, soft palate collapse, and hypopharyngeal collapse. The cine magnetic resonance image (MRI) is useful in evaluating the upper airway in those patients who have not achieved a normal polysomnogram after T&A surgery. STUDY DESIGN: Prospective case series. METHODS: Fifteen children with Down syndrome who had previously undergone a T&A but continued to have abnormal postoperative polysomnograms underwent a cine MRI with fast gradient cine MRI images. RESULTS: The cine MRI identified different areas and levels of obstruction that ultimately affected the children's treatment courses. Recurrent adenoid tissue, glossoptosis, soft palate collapse, hypopharyngeal collapse, and enlarged lingual tonsils were identified. The results as well as several illustrative cases are presented. CONCLUSION: Cine MRI evaluates upper airway obstruction in children who may have multiple sources of obstruction causing their obstructive sleep apnea. This is particularly helpful in children with Down syndrome and craniofacial anomalies. This technology is useful in all children with complex upper airway obstruction. 相似文献

OBJECTIVE: Seek information about spinal cord safety for children with Down syndrome positioned for ear surgery. STUDY DESIGN: Prospective consecutive patients, each serving as his or her own control. METHODS: Somatosensory evoked potentials were recorded from 17 children who were undergoing elective otolaryngological surgery. None of the patients had neurological symptoms or physical examination findings suggesting cervical spinal cord embarrassment. Specifically, muscle tone was normal or mildly reduced globally, consistent with Down syndrome, and deep tendon reflexes were normal and not appreciably different in the upper and lower extremities. On plain lateral radiographs obtained in the neutral, flexed, and extended positions, the patients' cervical spines were normal. RESULTS: When the anesthetized children had their necks placed in either right or left 60 degrees rotation, no significant change in somatosensory latency or amplitude was found. With more than 99.999% certainty, neurologically intact children with Down syndrome with normal plain cervical spine radiographs were not exposed to extra risks by 60 degrees neck rotation during surgery. CONCLUSION: Patients with Down syndrome who are neurologically intact and who have normal lateral neck radiographs do not appear at great risk with neck rotation. 相似文献

OBJECTIVES/HYPOTHESIS: The purpose of this study is to prospectively evaluate the airway size of children with Down syndrome (DS). Previous studies have observed an increase in postintubation stridor in children with DS. Anesthetic literature suggests using a smaller endotracheal tube in children with DS, but more specific recommendations are not offered. With this study, recommendations are presented for the appropriate endotracheal tube size to use in children with DS undergoing intubation. STUDY DESIGN: A prospective, nonrandomized study was performed on a cohort of 42 children with DS and 32 control subjects. Sizing of the airway was assessed through measurement of an air leak around the endotracheal tube at intubation. The size of the airway was also evaluated through measurements of the tracheal diameter at the "tracheotomy point" on magnetic resonance imagine (MRI) studies of the head and neck which were performed on a group of children with DS. These were compared with normative values of the tracheal diameter in children. METHODS: The proper size of endotracheal tube in a population of children with DS and in a group of normal controls was determined. The "proper size" of an endotracheal tube was defined as that size of tube which allowed an audible air leak around the tube between 10 and 30 cm of H2O pressure. Anesthetic technique was controlled and identical for all study subjects. Participants had no previous history of airway compromise, stridor, or previous intubation. Weight and age were recorded and evaluated for their influence on the results. A retrospective evaluation was made of MRI studies of the neck that were performed on children with DS. Using measurement techniques described by Reed et al., the tracheal diameters at the "tracheostomy point" were compared with normative values for children. Measurements were both obtained by the author and confirmed by a pediatric radiologist. RESULTS: Using this prescribed method to determine the proper size of endotracheal tube, the control group used endotracheal tubes that were predicted from established anesthesia charts and formulas. However, children with DS required endotracheal tubes at least two sizes smaller. Age was found to be a more reliable factor in predicting the endotracheal tube size. A table of endotracheal tube sizes for intubation in children with DS is presented. Evaluation of the tracheal diameter at the tracheotomy point revealed that children with DS have a smaller trachea when compared with control children. It is not only the subglottis that is smaller; the tracheal diameter as well must be assumed to be of a smaller diameter in children with DS. CONCLUSIONS: Children with DS have smaller airways than other children. This is because of an overall decrease in the diameter of the tracheal lumens. Initial intubation of a child with DS should be performed with an endotracheal tube at least two sizes smaller than would be used in a child of the same age without DS, to avert potential trauma to the airway. 相似文献

Mesenchymal chondrosarcoma of the sinonasal tract: a clinicopathological study of 13 cases with a review of the literature 总被引:1,自引:0,他引:1
OBJECTIVES/HYPOTHESIS: Mesenchymal chondrosarcoma of the sinonasal tract is a rare, malignant tumor of extraskeletal origin. Isolated cases have been reported in the English literature, with no large series evaluating the clinicopathological aspects of these tumors. STUDY DESIGN: Retrospective review. METHODS: Thirteen patients with sinonasal mesenchymal chondrosarcoma were retrieved from the Otorhinolaryngologic-Head and Neck Registry of the Armed Forces Institute of Pathology. RESULTS: Nine women and 4 men (age range, 11 to 83 y; mean age, 38.8 y) presented with nasal obstruction (n = 8), epistaxis (n = 7), or mass effect (n = 4), or a combination of these. No patients reported prior head and neck irradiation. The maxillary sinus was the most common site of involvement (n = 9), followed by the ethmoid sinuses (n = 7) and the nasal cavity (n = 5). Tumors had an overall mean size of 5.1 cm. Microscopically, the tumors displayed a small, blue, round cell morphology appearance arranged in a hemangiopericytoma-like pattern with foci of cartilaginous matrix. All cases were managed by surgery with adjuvant radiation therapy (n = 4) and/or chemotherapy (n = 3). The overall mean survival was 12.1 years, although five of six patients who developed local recurrences died of disease (mean survival, 6.5 y). Six patients were alive and disease free (mean survival, 17.3 y), and two patients were lost to follow-up. CONCLUSIONS: Mesenchymal chondrosarcoma of the sinonasal tract is an aggressive tumor with a predilection for young women. The pattern of growth and scarcity of cartilaginous matrix result in frequent misdiagnosis. Recurrence develops in approximately one-third of patients and seems to predict a poor prognosis. Aggressive, exenterative surgery combined with adjuvant therapy appears to yield the best clinical outcome. 相似文献

Acoustic vocal analysis is a simple and fast method that allows to differentiate normal from changed voices. There are few studies that analyze normal acoustic vocal parameters at different age ranges in children.AimsTo establish normative acoustic parameters of children's voice aged 4 to 12 years.MethodsTwo hundred and forty children were divided into four sub-groups by age: G1 (n-60; 4-5 years), G2 (n-60; 6-7 years), G3 (n-60; 8-9 years) and G4 (n-60; 10-12 years). The children's parents answered a questionnaire and the children were submitted to auditory acuity evaluation (Assessment of Transient Otoacoustic Emissions), acoustic vocal analyses, otorhinolaryngological and videolaryngoscopy exams.ResultsThe normal values for the acoustic vocal parameters studied were established according to age range and gender. As age increased, there was a decrease of f0 and APQ and an increased in SPI with statistical difference of these parameters. The vocal parameters did not differ between genders until the age of 12.Conclusionsthe characterization of the normative vocal patterns of children is an important reference for future studies. Some of the changes showed a direct relationship between age and a reduction of f0 and of APQ, and increase in SPI, with no difference between genders. 相似文献
