Sleep apnea surgery versus tracheostomy in children: an exploratory study of the comparative effects on quality of life

Secondary Le Fort III after Early Fronto-Facial Monobloc Normalizes Sleep Apnea in Faciocraniosynostosis: A Cohort Study

BACKGROUND

This study aims to assess the improvement of sleep apnea after secondary Le Fort III facial advancement with distraction (LF3) in faciocraniosynostosis (FCS) patients with sleep apnea who have previously undergone fronto-facial monobloc advancement (FFMBA) with distraction.

METHODS

Patients having undergone secondary LF3 were selected from a cohort of FCS patients with documented sleep apnea who had previously undergone fronto-facial monobloc advancement. Patient charts and polysomnographic records were reviewed. Apnea-hypopnea index (AHI) was recorded before and at least 6 months after secondary LF3. The primary outcome was normalization of AHI (less than 5/h was considered normal). Hierarchical multilevel analysis was performed to predict postoperative AHI evolution.

RESULTS

Seventeen patients underwent a secondary LF3, 7.0 ± 3.9 years after the primary FFMBA. The mean age was 9.6 ± 3.9 years. A total of 15 patients (88%) normalized their AHI. Two of four patients were decannulated (50%). There was a statistically significant decrease in AHI (preoperative AHI 21.5/h vs. 3.9/h postoperatively, p=0.003). Hierarchic multilevel modeling showed progressive AHI decrease postoperatively.

CONCLUSION

Secondary LF3 improves residual or relapsing sleep apnea in FCS patients who have previously had FFMBA.

Craniosynostosis: Monobloc Distraction with Internal Device and Its Variant for Infants with Severe Syndromic Craniosynostosis

The introduction of distraction osteogenesis to frontofacial monobloc advancement has increased the safety of the procedure. One hundred forty-seven patients with syndromic craniosynostosis underwent frontofacial monobloc advancement using 4 internal distractors. Twenty-five were aged 18 months or less. Ten patients presented with a tracheostomy, 5 (50%) were decannulated after surgery, and 3 others (30%) required an additional intervention before decannulation. Six patients required the addition of a transfacial pin and external traction. Very early frontofacial monobloc with 4 internal distractors is a safe and effective treatment to protect the ophthalmic, neurologic, and respiratory functions in infants with severe syndromic craniosynostosis.

The Family Impact of Having a Child with a Tracheostomy

OBJECTIVES

Measure the quality of life among families with children with tracheostomies.

METHODS

We performed a prospective cross-sectional analysis of families with children with tracheostomies utilizing the PedQL Family Impact Module-a validated quality of life assessment. We determined if scores were impacted by demographics using regression analysis. We also compared the tracheostomy sample's scores to a previously published cohort of children with severe cerebral palsy and birth defects that required home nursing or nursing home placement using the student's t-test. We determined the effect size of the difference between the two groups using the Cohen's d test.

RESULTS

Ninety-eight families are included in the study. The average (SD) age of tracheostomy placement was 1.6 (3.5) years. The population was 60% (59/98) male and 39% (38/98) Hispanic. The principal reason for tracheostomy was due to respiratory failure (76 out of 98; 78%). The mean (SD) total Family Impact score was 76 (19). The lowest domain score was daily activity problems, mean (SD) = 67 (30) followed by worry (mean = 69, SD = 24). The lowest question score was, "I worry about my child's future," mean (SD) = 52 (37). When compared to the comparison group of medically fragile children, the scores were statistically similar except for communication totals where tracheostomy patients reported superior scores (78.3 vs. 62.9, 95% CI, -26 to -4.8, P = .005, Cohen's d = -0.66).

CONCLUSION

The presence of a tracheostomy is associated with QOL scores like other medically fragile children.

A Descriptive Qualitative Study of Home Care Experiences in Parents of Children with Tracheostomies

PURPOSE

The number of pediatric patients who require a long-term tracheal tube at home is gradually increasing. Studies have demonstrated that the parents of these children report high levels of stress, anxiety and other negative emotions as early as shortly after discharge from the hospital. The purpose of this study is to describe the home care experiences of parents of children with tracheostomies during the transition from hospital to home in China to more effectively address their needs.

DESIGN AND METHODS

This study used a qualitative descriptive design and face-to-face interviews with semi-structured questions to learn about the home care experiences of parents whose children had undergone a tracheostomy.

RESULTS

Thirteen parents were recruited from the otorhinolaryngology outpatient ward of Xinhua Hospital in Shanghai, China. These parents described three categories of home care experiences: "direct care overload," "psychological overload," and "personal growth." Subcategories included parental "role change," "from helplessness to skillfulness," "lack of professional support," "anxiety and depression," and "social isolation." They also reported personal growth, which was mainly reflected by "changing their perspectives" and "developing potential."

CONCLUSION

Although the findings of this study indicate that the physical and psychological overload reported by parents of children with tracheostomies during home care is inevitable, a better understanding of parents' caring experiences among professionals may facilitate clinical practice and promote continued community nursing care in China.

PRACTICE IMPLICATIONS

Parents hope to receive systematic education during hospitalization, including web-based video education for skills training after discharge. In addition, parents desire public recognition so that they can participate in normal family and community activities.

Tracheostomy for paediatric obstructive sleep apnoea: A systematic review

OBJECTIVE

To search the international literature (any language) for publications reporting outcomes of tracheostomy performed to treat obstructive sleep apnoea in children.

METHOD

Data sources included: Google Scholar, Cumulative Index to Nursing and Allied Health Literature, Embase, Scopus, and PubMed/Medline. Four authors searched systematically through to 20 January 2018.

RESULTS

A total of 597 studies were screened; 64 were downloaded and 11 met criteria. A total of 196 patients underwent tracheostomy (mean age, 4.2 years; range, newborn to 18 years); 40 had detailed qualitative data and 6 had detailed quantitative data. Apnoea/hypopnoea index showed a 97 per cent reduction (n = 2) and apnoea index showed a 98 per cent reduction (n = 3). Lowest oxygen saturation showed a 34 oxygen saturation point improvement (n = 3). Several patients demonstrated significant improvement in breathing. All identified patients were syndromic, had significant co-morbidities or had severe obstructive sleep apnoea.

CONCLUSION

Based on reports of children who have undergone a tracheostomy, for whom there are pre- and post-operative data, tracheostomy appears to be a successful treatment for obstructive sleep apnoea. However, additional research is recommended given the small number of patients in the literature.

The Relationship Between Sleep and Cognition in Children Referred for Neuropsychological Evaluation: A Latent Modeling Approach

Children with conditions affecting cognitive processes experience high levels of sleep disturbance, which may further compound the cognitive ramifications of their disorders. Despite this, existing studies in this area have been primarily confined to only particular diagnostic groups and/or a limited scope of sleep and cognitive parameters. The current study characterized the nature of sleep problems and examined the relationship between a wide range of sleep-related problems and cognitive functioning in a large (N = 103) diagnostically heterogeneous sample of youth (aged 6–16) referred for neuropsychological assessment. Structural equation modeling was used to examine the relationship between sleep-related problems (i.e., daytime sleepiness, sleep onset latency, sleep fragmentation, sleep time variability, sleep debt) and cognitive performance (i.e., executive functioning, sustained attention, memory, processing speed). Sleep fragmentation emerged as the most prominent sleep-related problem in the present sample. Structural equation modeling demonstrated a negative association between sleep-related problems and cognition that did not reach statistical significance (β = −0.084, p = 0.629). The current statistical approach may be used as a conceptual framework for future work examining these multi-dimensional constructs in a parsimonious fashion.

Tracheostomy for Severe Pediatric Obstructive Sleep Apnea: Indications and Outcomes

Objectives (1) To describe characteristics of pediatric patients undergoing tracheostomy for obstructive sleep apnea (OSA). (2) To highlight perioperative events and outcomes of the procedure. Study Design Case series with chart review. Setting Four tertiary care academic children's hospitals. Subjects and Methods Twenty-nine children aged <18 years from January 1, 2010, to December 31, 2015, who underwent tracheostomy for severe OSA, defined as an apnea-hypopnea index (AHI) >10, were included in the study. Data on patient characteristics, polysomnographic findings, comorbidities, and perioperative events and outcomes were collected and analyzed. Results Twenty-nine patients were included. Mean age at tracheostomy was 2.0 years (95% CI, -2.2 to 6.2). Mean body mass index z score was -1.2 (95% CI, -4.9 to -2.5). Mean preoperative AHI was 60.2 (95% CI, -15.7 to 136.1). Mean postoperative intensive care unit stay was 23.2 days (95% CI, 1.44-45.0). One procedure was complicated by bronchospasm. Thirteen patients had craniofacial abnormalities; 10 had a neurologic disorder resulting in hypotonia; and 5 had a diagnosis of laryngomalacia. Mean follow-up was 30.6 months (95% CI, -10.4 to 71.6). Six patients were decannulated, with a mean time to decannulation of 40.8 months (95% CI, 7.9-73.7). Five patients underwent capped sleep study prior to decannulation with a mean AHI of 6.6 (95% CI, -9.9 to 23.1) and a mean oxygen nadir of 90.0% (95% CI, 80%-100%). Conclusion OSA is an uncommon indication for tracheostomy in children. Patients who require the procedure usually have an associated syndromic diagnosis resulting in upper airway obstruction. The majority of children who undergo tracheostomy for OSA will remain dependent at 24 months.

The Glasgow Children's Benefit Inventory: A New Instrument for Assessing Health-Related Benefit after an Intervention

Most health-related quality-of-life measures make an assessment at a single point in time. Comparing results before and after an intervention is often difficult, because the difference measured is usually small compared with the variation between individuals. A retrospectively applied measure specifically worded to assess benefit would be very useful for clinical research. Such a measure exists for adults. We aimed to develop a similar measure for children. We chose potential items after reviewing existing health-related quality-of-life measures, published literature, and parental interviews. A draft questionnaire was given to a group of parents and modified. The resulting Glasgow Children's Benefit Inventory (GCBI) comprised 24 questions on the consequences of a specified intervention on various aspects of the child's day-to-day life, without reference to any specific symptoms, and was worded to apply to children of any age. The questionnaire was mailed to the parents of all 1,777 children who had undergone tonsillectomy or ventilation tube insertion at one hospital during the period January 1998 to December 2001. There were 670 questionnaires returned. The GCBI scores correlated well with parental satisfaction with surgery and with estimates of technical success (residual sore throats, reported hearing impairment, ear infections). The questionnaire had high internal consistency. Factor analysis showed 4 dimensions in the pattern of responses relating to emotion, physical health, learning, and vitality. The GCBI is a means to retrospectively assess benefit after an intervention in children, and we have shown initial evidence of reliability and validity. Although not restricted to any branch of pediatric medicine, it is eminently suitable for use in pediatric otolaryngology.

Update on paediatric obstructive sleep apnoea

Obstructive sleep apnoea (OSA) is one of the most common causes of sleep-disordered breathing (SDB) in children. It is associated with significant morbidity, potentially impacting on long-term neurocognitive and behavioural development, as well as cardiovascular outcomes and metabolic homeostasis. The low grade systemic inflammation and increased oxidative stress seen in this condition are believed to underpin the development of these OSA-related morbidities. The significant variance in degree of end organ morbidity in patients with the same severity of OSA highlights the importance of the interplay of genetic and environmental factors in determining the overall OSA phenotype. This review seeks to summarize the current understanding of the aetiology and mechanisms underlying OSA, its risk factors, diagnosis and treatment.

Obstructive sleep disordered breathing in 2- to 18-year-old children: diagnosis and management

This document summarises the conclusions of a European Respiratory Society Task Force on the diagnosis and management of obstructive sleep disordered breathing (SDB) in childhood and refers to children aged 2-18 years. Prospective cohort studies describing the natural history of SDB or randomised, double-blind, placebo-controlled trials regarding its management are scarce. Selected evidence (362 articles) can be consolidated into seven management steps. SDB is suspected when symptoms or abnormalities related to upper airway obstruction are present (step 1). Central nervous or cardiovascular system morbidity, growth failure or enuresis and predictors of SDB persistence in the long-term are recognised (steps 2 and 3), and SDB severity is determined objectively preferably using polysomnography (step 4). Children with an apnoea-hypopnoea index (AHI) >5 episodes·h(-1), those with an AHI of 1-5 episodes·h(-1) and the presence of morbidity or factors predicting SDB persistence, and children with complex conditions (e.g. Down syndrome and Prader-Willi syndrome) all appear to benefit from treatment (step 5). Treatment interventions are usually implemented in a stepwise fashion addressing all abnormalities that predispose to SDB (step 6) with re-evaluation after each intervention to detect residual disease and to determine the need for additional treatment (step 7).

WITHDRAWN: Adenotonsillectomy for obstructive sleep apnoea in children

This review has been withdrawn because it has been split into the following reviews: '(Adeno)tonsillectomy versus non‐surgical management of obstructive sleep apnoea syndrome (OSAS) in children' (Schilder 2015) and 'Tonsillectomy versus tonsillotomy in children with sleep‐disordered breathing (including obstructive sleep apnoea)' (protocol) (Blackshaw 2014).

The editorial group responsible for this previously published document have withdrawn it from publication.

Parents' experiences and views of caring for a child with a tracheostomy: a literature review

OBJECTIVES

To review the published/reported experiences and views of parents' whose child has had a tracheostomy. To date, no review has focused specifically on parents' experiences and views of having a child with a tracheostomy.

METHODS

MEDLINE, CINAHL, PsycINFO and Embase were systematically searched from 1990 to 2012 and a review of reference lists was conducted. The review draws on articles where parents' views of caring for their child's tracheostomy were either the sole focus of the research or where parental views of caring for their child's tracheostomy have been sought as a subsidiary aim. Studies relating to the aims of the review were examined using quality appraisal tools and in line with criteria for inclusion of studies. Studies were excluded if findings were about adults, studies that only focused on children's or sibling's views were not based on empirical work (e.g. literature reviews or expert commentary) or were not published in the English language. Findings were summarised under thematic headings.

RESULTS

The systematic database search identified 442 citations of which 10 were eligible for inclusion in the review. Of those 10 studies six were quantitative and four qualitative. Only one paper published qualitative data specifically on parents' experiences about their tracheotomised child. The three main themes identified were parents' experiences of caregiving, their social experiences and experiences of service delivery of having a child with a tracheostomy. Although parents encountered emotional and social challenges, some positive responses to these challenges were reported.

CONCLUSION

This review identifies a lack of qualitative research on parents' views of having a child with a tracheostomy. Issues surrounding parental management of tracheostomy require further investigation. This review has identified the need to elicit parents' longitudinal experiences of having a child with a tracheostomy.

Adenotonsillectomy for obstructive sleep apnoea in children

BACKGROUND

Current treatment of sleep apnoea in children consists of largely surgical based treatments. Adenotonsillectomy is the most commonly used intervention to treat sleep apnoea in children.

OBJECTIVES

To determine the efficacy of adenotonsillectomy in the treatment of obstructive sleep apnoea in children.

SEARCH STRATEGY

The Cochrane Airways Group Specialised Register was searched with pre-specified terms. Searches were current as of August 2008.

SELECTION CRITERIA

Randomised trials recruiting children with a diagnosis of obstructive sleep apnoea.

DATA COLLECTION AND ANALYSIS

Two reviewers examined the search results and collected data from the studies in terms of their characteristics before deciding which ones would be included in the review.

MAIN RESULTS

One study met the review entry criteria. This study addressed the relative merits of two surgical techniques in treating OSA in children (temperature controlled radiofrequency tonsillectomy and adenoidectomy, and complete tonsillectomy and adenoidectomy). No significant difference was apparent for either symptoms or respiratory disturbance index. More children in the TCFR&A group were able to return to normal diet at 7 days compared with complete T&A. No significant complications were observed in the study.

AUTHORS' CONCLUSIONS

One small study failed to find a difference between two surgical techniques, although return to normal diet was more frequent in the group treated by temperature controlled radiofrequency tonsillectomy and adenoidectomy. At present there is still debate as to the criteria required to diagnose significant obstructive sleep apnoea in children. Also the natural history of the condition has not been fully delineated. There is an absence of randomised controlled trials investigating the efficacy of treatment of confirmed obstructive sleep apnoea with adenotonsillectomy in children. Research is required before recommendations for the treatment of obstructive sleep apnoea in children can be formulated. The quality of research in this area could be improved with the use of sleep studies at baseline to determine the extent of severity of sleep apnoea in children who are recruited to studies in this area. Long-term follow up is also required in order to explore the effect of adenotonsillectomy on paediatric sleep apnoea.

Awake upper airway obstruction in children with spastic quadriplegic cerebral palsy

OBJECTIVE

Some children with severe cerebral palsy develop symptoms of upper airway obstruction (UAO) while awake. The aetiology, natural history and treatment of this complication have not previously been systematically described. This study documents a case series of children with severe cerebral palsy admitted to hospital because of severe awake UAO and reviews the relevant literature.

METHODS

The case records of children admitted to hospital with UAO while awake over an 8-month period were reviewed. Details of antecedent illness, comorbidities, acute management and follow up were collated. One case is presented in detail.

RESULTS

Eight children were admitted with UAO. Seven children required intensive care admission. One child died, and two underwent tracheostomy. Nasendoscopy showed pharyngeal collapse without anatomical obstruction in the majority. One child was discovered to have a brainstem malignancy.

CONCLUSIONS

Upper airway obstruction is a potentially severe and life-threatening complication of cerebral palsy. In this series, a majority of children had obstruction related to pharyngeal hypotonia and collapse. This can lead to prolonged hospitalization and intensive care admission. It may raise difficult management issues.

Pediatric Sleep-Related Breathing Disorders and Restless Legs Syndrome

Sleep-related breathing disorders and restless legs syndrome have traditionally been felt to affect primarily adults. Recent research suggests that these conditions are surprisingly common in children as well, and that clinical manifestations may differ considerably from those seen in adults. This review summarizes the clinical characteristics, epidemiology, pathophysiology, and treatment of sleep-related breathing disorders and restless legs syndrome in children. Particular emphasis is placed on recent research and on how the presentation and treatment of these conditions are different in children compared with adults.

Obstructive sleep apnea in children

Despite increasing recognition of childhood obstructive sleep apnea syndrome (OSAS) as a significant public health problem, treatment of the condition remains inconsistent. Some children are screened using polysomnography and treated only when objective respiratory disturbances are identified. Many others receive adenotonsillectomy based only on signs and symptoms of upper airway obstruction without ever having a formal sleep study. Outcome-based data regarding the effectiveness of adenotonsillectomy, continuous positive airway pressure, and other treatments for childhood OSAS remain extremely limited. In this article, the major therapeutic options for treatment of childhood OSAS are reviewed. Adenotonsillectomy remains the most frequently used treatment for uncomplicated OSAS in children, but residual airway obstruction persists in a notable minority of patients. Nasal continuous positive airway pressure is used for children who are not good surgical candidates or who have failed previous surgical treatment, but is sometimes not tolerated by young children or their parents. Various alternative treatments are used on an individualized basis for children who cannot use the two first-line therapies for sleep apnea.

Lymphatic Malformation of the Lingual Base and Oral Floor

BACKGROUND

Lymphatic malformation of the tongue and floor of the mouth is associated with chronic airway problems, recurrent infection, and functional issues related to speech, oral hygiene, and malocclusion. There are no accepted anatomic guidelines or treatment protocols.

METHODS

This retrospective review focused on anatomic extent, treatment, complications, and airway management in 31 patients with lymphatic malformation of the lingual base and oral floor.

RESULTS

Involved adjacent structures included the neck (77 percent), mandible (41 percent), face (42 percent), lips (10 percent), pharynx (45 percent), and larynx (26 percent). Fifty-eight percent of patients required tracheostomy during infancy; decannulation was possible in two-thirds of these patients. Management included resection alone (42 percent), resection and sclerotherapy (26 percent), resection and laser coagulation (16 percent), sclerotherapy and laser coagulation (16 percent), and resection and radiofrequency ablation (3 percent). Resection involved the neck (58 percent), floor of the mouth (52 percent), and tongue (42 percent); there were often multiple procedures. Aspiration was tried with little success in 10 percent of patients. Virtually all patients had residual abnormal lymphatic tissue. Complications and posttherapeutic problems included infection (81 percent), neural damage (27 percent), difficulty in speech (23 percent), feeding problems (10 percent), and seroma or hematoma (6 percent). Associated dental/orthognathic conditions, particularly prognathism and anterior open bite, were documented in one-third of patients.

CONCLUSIONS

The initial step in the protocol is control of the neonatal airway. Staged cervical resection is undertaken in late infancy to early childhood; resection should also include abnormal tissue in the oral floor. Sclerotherapy is primarily for macrocystic disease or secondarily for recurrent cysts following partial extirpation. Vesicles of the mucous membranes and dorsal tongue are treated either by sclerotherapy, laser (carbon dioxide, yttrium-aluminum-garnet, or potassium-titanyl-phosphate), or radiofrequency ablation. Reduction for macroglossia is indicated for persistent protrusion or to allow correction of malocclusion. Embolization controls lingual bleeding. Orthognathic procedures are undertaken at the appropriate age, only after lingual size and position are acceptable.

Internal mandibular distraction to relieve airway obstruction in infants and young children with micrognathia

Micrognathia may cause upper airway obstruction requiring complex medical interventions and sometimes tracheostomy. The role of distraction techniques to lengthen the mandible is yet to be clarified. The aim of this paper is to present a series of five cases in which mandibular lengthening by osteotomy and internal distraction was used to relieve airway obstruction. Five patients whose ages ranged from 4-39 months (mean, 15 months) were managed at our center with internal distraction osteogenesis to relieve airway obstruction. Three patients had a tracheostomy, and two patients had refractory airway obstruction prior to distraction. Following osteotomy and insertion of internal distraction devices, the mandible was distracted a mean of 17 mm (range, 15-25 mm). The distraction devices were removed at the end of a consolidation period ranging from 3-10 weeks. Two of 3 patients with a tracheostomy were decannulated, while the third patient with tracheostomy is awaiting choanal atresia repair before being decannulated. The two patients who were not managed with a tracheostomy but who had persistent upper airway obstruction have not required further airway intervention after mandibular distraction. In conclusion, mandibular lengthening by distraction osteogenesis can relieve airway obstruction in infants and small children. This is a promising new technique that may avoid the need for tracheostomy in some infants with micrognathia, and facilitate early decannulation in those who have a tracheostomy.

Quality of life in obstructive sleep apnea: a systematic review of the literature

OBJECTIVE

To review the literature on obstructive sleep apnea (OSA) and health-related quality of life (HRQOL).

BACKGROUND

OSA affects nearly one in four men and one in ten women aged 30-60 years in the United States. Health consequences of OSA can include neuropsychiatric and cardiovascular sequela that disrupt professional, family, and social life and negatively impact HRQOL.

METHODS

We conducted a comprehensive review of the literature on HRQOL and OSA, with special attention paid to instruments developed specifically for OSA.

RESULTS

Generic instruments used to study HRQOL and OSA include: Medical Outcomes Study Short Form-36, Nottingham Health Profile, Sickness Impact Profile, Functional Limitations Profile, EuroQol, and Munich Life Quality Dimension List. Specific instruments include: Calgary Sleep Apnea Quality of Life Instrument, Functional Outcomes of Sleep Questionnaire, OSA Patient Oriented Severity Index, the OSA-18, and Cohen's pediatric OSA surgery quality of life questionnaire.

CONCLUSIONS

OSA patients have impaired HRQOL when compared with healthy age- and gender-matched controls. Treatment with continuous positive airway pressure appears to improve HRQOL. Other treatment modalities have not been rigorously studied. In addition, more data are needed from preference-based measures that allow conversion to utility scores, which can be used to calculate quality-adjusted life years and cost-effectiveness ratios.

Obstructive sleep apnea in children: an update

The diagnosis of obstructive sleep apnea in children requires clinical suspicion supplemented with the use of specific diagnostic tests. Polysomnography remains the key to diagnosis, and helps to assess the need for treatment, the risk for perioperative respiratory compromise, and the likelihood of persistent OSAS after treatment. Adenotonsillectomy is the mainstay of treatment, although children with complex medical conditions that affect upper airway anatomy and tone may require additional treatment.

Midface distraction to alleviate upper airway obstruction in achondroplastic dwarfs

OBJECTIVE

The use of midface distraction in patients with achondroplasia and upper airway obstruction secondary to midface hypoplasia has not been reported. In this report, we review the treatment of two patients with severe midface hypoplasia and obstructive sleep apnea secondary to achondroplasia using midface distraction osteogenesis.

DESIGN, SETTING, AND PATIENTS

Two patients with achondroplastic dwarfism and midface hypoplasia with airway obstruction were treated in a tertiary referral center for craniofacial disorders.

RESULTS AND CONCLUSIONS

Both patients had their tracheostomies decannulated after midface distraction of 25 mm. Midface distraction osteogenesis is useful to alleviate upper airway obstruction from midface hypoplasia seen in achondroplasia.

Adenotonsillectomy for obstructive sleep apnoea in children

BACKGROUND

Current treatment of sleep apnoea in children consists of largely surgical based treatments. Adenotonsillectomy is the most commonly used intervention to treat sleep apnoea in children.

OBJECTIVES

To determine the efficacy of adenotonsillectomy in the treatment of obstructive sleep apnoea in children.

SEARCH STRATEGY

The Cochrane Airways group specialised register was searched with pre-specified terms.

SELECTION CRITERIA

Randomised trials recruiting children with a diagnosis of obstructive sleep apnoea.

DATA COLLECTION AND ANALYSIS

A total of 196 references were identified from electronic searching. Twenty studies were retrieved and none met the inclusion criteria of the review.

MAIN RESULTS

Due to the absence of randomised trial data, no results could be ascertained.

REVIEWER'S CONCLUSIONS

At present there is still debate as to the polysomnographic criteria required to diagnose significant obstructive sleep apnoea in children. Also the natural history of the condition has not been fully delineated. There is an absence of randomised controlled trials investigating the efficacy of treatment of obstructive sleep apnoea with adenotonsillectomy in children and, therefore, further research is required before recommendations for the treatment of obstructive sleep apnoea in children can be formulated.

Surgical strategies in the treatment of complex obstructive sleep apnoea in children

Complex OSA in children is a challenging problem that requires careful team management. Evaluation includes history, physical examination and appropriate radiological and endoscopic studies. Twelve-channel polysomnography, with or without a pH probe, is mandatory in children with OSA to determine the severity and to document the efficacy of treatment. A variety of individual problems and nuances arise and will continue to do so. Clinical experience and a high degree of suspicion in the craniofacial population is necessary to rule out the existence of OSA in a given patient. Newer treatment modalities, such as distraction osteogenesis of the mandible and midface, have revolutionised treatment of OSA during childhood. Although still the gold standard of care, tracheostomy is not a benign procedure and the toll on both the patient and family can be devastating.

Final validation of the Pediatric Tracheotomy Health Status Instrument (PTHSI)

OBJECTIVE

We sought to describe the development and final testing of an instrument designed to evaluate the impact of tracheotomy on the health-related quality of life of affected families in whom a child has had a tracheotomy (the Pediatric Tracheotomy Health Status Instrument [PTHSI]).

STUDY DESIGN

This cross-sectional study designed to analyze a disease-specific health status instrument to establish validity and reliability.

RESULTS

The PTHSI was initially pilot tested in 130 families during a 3-month period from September through November 2000. After initial analysis and revision, from January 2001 through July 2001, 154 different families completed the revised instrument. The overall Cronbach's alpha coefficient for the instrument was 0.91, with domain-specific coefficients ranging from 0.66 for physical symptoms to 0.87 for caregiver stress and coping. Specific criterion validity analysis produced a Pearson correlation coefficient of 0.8 (P < 0.0001). Construct validity testing via Wilcoxon matched sum testing suggested statistically significant differences between subpopulations (P < 0.001).

CONCLUSION

After initial testing and revision of the PTHSI, final instrument administration and analysis reveal the instrument to be valid and reliable. Future studies are planned to evaluate its responsiveness in longitudinal application.

Obstructive sleep apnea surgery: patient perspective and polysomnographic results

OBJECTIVE

The goal of this study was to assess the outcomes of obstructive sleep apnea (OSA) surgery based on the patient perspective and polysomnographic data.

STUDY DESIGN

Fifty-six patients with severe OSA completed the 2-phase reconstructive protocol. A minimum of 6 months after the phase II surgery and after the postoperative polysomnography, questionnaires with visual analog scales (VAS 0-10) were mailed to the patients to assess their perceptions of treatment results.

RESULTS

Forty-two (75%) questionnaires were returned. The mean patient age was 46.3 years. The mean respiratory disturbance index improved from 58.7 to 10.0. The mean lowest oxygen saturation improved from 76.3 to 87.3%. All 42 patients reported improved sleep (VAS 8.7). Although 10 patients reported changes in speech, the changes were insignificant, with 9 of the patients scoring 0 on the VAS (VAS 0.08 +/-0.3). Five patients reported changes in swallowing, and their VAS scores were 0.5, 0.9, 1.0, 2.7, and 6.9 (mean VAS 2.4+/-2.7). Forty patients (95%) were satisfied with their results and would undergo the reconstruction again.

CONCLUSION

Surgical airway reconstruction for severe OSA is a highly effective treatment option base on the objective as well as the subjective assessment.

Distraction osteogenesis for obstructive apneas in patients with congenital craniofacial malformations

Infants with congenital craniofacial malformations often have associated severe mandibular hypoplasia causing obstruction of the hypopharynx by retroposition of the base of the tongue into the posterior pharyngeal airway. Management depends on the severity of the airway obstruction. Most cases can be managed by prone positioning until the infant outgrows the problem at 3 to 6 months of age. In more critical cases, monitoring of oxygen saturation, temporary placement of a nasopharyngeal tube, and placement of an endotracheal tube will be useful procedures. Tracheotomy is an effective method for more severe cases, but longstanding tracheotomies result in high morbidity and occasional mortality. Mandibular distraction was performed in seven patients, ranging in age from 1 to 18 months, with critical obstructive apnea secondary to mandibular hypoplasia characterized by an apnea/hypopnea index greater than 20 apneas per hour and oxygen saturation below 80 percent. Two patients were tracheotomized previously. Mandibular lengthening, from 16 to 25 mm on the left side and from 10 to 22 mm on the right, was achieved in 21 to 25 days. Improvement of airway obstruction parameters was measured on polysomnograms and lateral cephalograms. Mandibular lengthening by gradual distraction is a successful method for young patients with severe mandibular hypoplasia causing critical obstructive apneas. Avoidance of tracheotomy or early decannulation in previously tracheotomized patients is a great advantage for patients with congenital craniofacial malformation.

Pediatric obstructive sleep apnea syndrome

Pediatric obstructive sleep apnea occurs in about 2% of children, and manifests as snoring, difficulty breathing, and witnessed apneic spells. Daytime symptoms include excessive sleepiness with poor performance and behavior problems. Severe forms may be associated with failure-to-thrive or death. The gold standard diagnostic procedure is overnight polysomnography and is indicated in high-risk patients. While most pediatric patients with obstructive sleep apnea can be treated with tonsillectomy and adenoidectomy; uvulopalatopharyngoplasty, tracheotomy, or other procedures are sometimes indicated. Nonsurgical treatment with continuous positive airway pressure is used in some children. Postoperative management in high-risk children includes careful perioperative monitoring and postoperative polysomnography.
