Nasopharyngeal airways in Pierre Robin Syndrome

Non-Surgical Respiratory Management in Relation to Feeding and Growth in Patients with Robin Sequence; a Prospective Longitudinal Study

OBJECTIVE

To reflect upon our non-surgical respiratory management by evaluating clinical outcomes regarding airway, feeding, and growth during the first year of life in patients with Robin Sequence.

DESIGN

Prospective study.

SETTING

Sophia Children's Hospital, Rotterdam, the Netherlands.

PATIENTS/ PARTICIPANTS

36 patients with Robin Sequence who were treated between 2011 and 2021.

INTERVENTIONS

Positional therapy and respiratory support.

MAIN OUTCOME MEASURE(S)

Data on respiratory outcomes included polysomnography characteristics and capillary blood gas values. Feeding outcomes were based on the requirement of additional tube feeding. Outcomes on growth were expressed as standard-deviation-scores (SDS) for weight-for-age (WFA) and height-for-age (HFA).

RESULTS

Twenty patients were treated with positional therapy (PT), whilst the other 16 patients required respiratory support. Twenty-two patients presented with non-isolated Robin Sequence (RS). During the first year of life, obstructive apnea hypopnea index decreased, oxygen levels enhanced, and capillary blood gas values improved. Eighty-six percent (31/36) experienced feeding difficulties, which completely resolved in 71% (22/31) during their first year of life. From start treatment, to stop treatment, to the age of 1 year, the SDS WFA worsened from -0.40 to -0.33 to -1.03, respectively.

CONCLUSIONS

Non-surgical respiratory treatment resulted in an improvement of respiratory outcomes to near normal during the first year of life in patients with RS. These patients often experience feeding difficulties and endure impaired weight gain up to 1 year of age, despite near normalization of breathing. The high prevalence of feeding difficulties and impaired weight for age indicate the urgency for early recognition and adequate treatment to support optimal growth.

Pierre Robin and breathing: What to do and when?

Robin sequence is characterized by mandibular retrognathia, airway obstruction, and glossoptosis; 80%-90% also have a cleft palate. Various treatment approaches exist, and although controlled studies are rare, objective assessment of treatment outcomes that address the leading clinical issues, namely obstructive sleep apnea and failure to thrive, are essential. Sleep-disordered breathing may be detected using cardiorespiratory polygraphy or polysomnography. Pulse oximetry alone may miss infants with frequent obstructive apneas, yet no intermittent hypoxia. Among conservative treatment options, the Tubingen Palatal Plate with a velar extension shifting the tongue base forward is the only approach that corrects the underlying anatomy and that has undergone appropriate evaluation. Of the surgical treatment options, which are not necessarily the first line of therapy, mandibular distraction osteogenesis (MDO) is effective and has been most extensively adopted. Notwithstanding, it is puzzling that MDO is frequently used in some countries, yet hardly ever in others, despite similar tracheostomy rates. Thus, prospective multicenter studies with side-by-side comparisons aimed at identifying an optimal treatment paradigm for this potentially life-threatening condition are urgently needed.

Pediatric nasopharyngeal airways expand when exposed to saline

PURPOSE

Nasopharyngeal airways (NPA) are commonly used to relieve upper airway obstruction in children. They must be sized to extend posterior to the tongue base but remain above the epiglottis. To avoid obstruction from nasal secretions, frequent irrigation with saline is required. We hypothesized that NPAs would swell when exposed to saline irrigation.

METHODS

Twenty-five green Rusch NPA size 12, 14, 16, 18 and 20 Fr were submerged in 2 L of normal saline for 15 days. Tube length, inner diameter, outer diameter and wall thickness were measured on days 1,2,3,4,5,10, and 15 and compared using two-way repeated measures ANOVA and paired t-tests with Bonferroni correction.

RESULTS

All dimensions increased significantly with exposure to saline. Increases in length, inner diameter, outer diameter and wall thickness were dependent on original tube size (p < 0.05) and duration of exposure to saline (p < 0.001). The increase in tube length was greatest over the first five days.

CONCLUSION

NPAs expand significantly when exposed to saline with the greatest increase in length occurring in the first five days. This could lead to gagging or airway obstruction in small children. Patients with NPAs should be monitored closely for these signs and new materials should be sourced to prevent these issues.

Tongue Lip Adhesion in the Treatment of Robin Sequence: Respiratory, Feeding, and Surgical Outcomes

OBJECTIVE

Objective evaluation of the efficacy of tongue lip adhesion (TLA) in the management of Robin sequence (RS).

STUDY DESIGN

Retrospective cohort study.

SETTING

Tertiary referral hospital.

PATIENTS, PARTICIPANTS

The craniofacial database of Amsterdam UMC, Vrije Universiteit Amsterdam was searched to identify infants with RS who underwent tong lip adhesion (TLA). Forty-one RS infants who underwent TLA from 1993 to 2016 were identified.

INTERVENTIONS

TLA.

MAIN OUTCOME MEASURE

The outcome measures were pre- and postoperative polysomnography results, nutritional status, weight gain, age at operation, hospital stay length, extubation time after TLA, and complications.

RESULTS

Forty-one RS patients were included who had TLA at an average age of 26.6 days. In 16 cases a pre- and postoperative polysomnography was performed. In 13 of these cases (81.3%) improvement was observed, in 2 (12.5%) the results were inconclusive, and in 1 (6.3%) no improvement was seen. Patients were extubated after a mean of 2.2 days.The mean hospital stay was 40.2 days. Reintervention was needed in 7 patients because of a wound dehiscence. The mean age of TLA release was 9.7 months. At discharge, 9 (22%) children still needed total nutritional support for persistent feeding difficulties. The average growth from birth to adhesion release was 4.6 kg.

CONCLUSION

This cohort demonstrates that TLA is a successful procedure in children with RS in terms of respiratory, feeding, and growth outcome. Only minor complications were seen in our cohort.

Infant Mandibular Distraction for Upper Airway Obstruction: A Clinical Audit

Background:

Mandibular distraction osteogenesis (MDO) is an effective method of treating upper airway obstruction (UAO) in micrognathic infants. The short-term outcomes include relief of UAO, avoidance of tracheostomy, and prompt discharge from hospital. However, it is a significant surgical procedure with potential associated morbidities. This study describes a cohort of infants managed using MDO over a twelve-year period.

Methods:

A retrospective chart review was undertaken for children who had MDO before the age of 5 years between 2000 and 2012. This was followed by a clinical review of the same cohort specifically looking for dental anomalies, nerve injuries, and scar cosmesis.

Results:

Seventy-three children underwent MDO at a mean age of 2 months [interquartile range (IQR), 1.7–4.2] for nonsyndromic infants and 3.3 months (IQR, 2.1–7.4) for those with syndromes. Infants were discharged from hospital, on average, 15 days after procedure. After MDO, of the 9 who were previously tracheostomy dependent, 5 (56%) were decannulated within 12 months and none of the nontracheostomy-dependent children required further airway assistance. The majority of children required supplemental feeding preoperatively but, 12 months postoperatively, 97% of the nonsyndromic infants fed orally. Thirty-nine children (53%) were reviewed clinically [median age, 5.1 y (IQR, 3.9–6.5)] with 18 being syndromic. Many of the mandibular first permanent and second primary molars had developmental defects, but there was a low rate of neurosensory deficit and good scar cosmesis.

Conclusions:

This study contributes further to the evidence base underpinning the management of micrognathic infants with UAO.

Craniofacial syndromes and sleep-related breathing disorders

Children with craniofacial syndromes are at risk of sleep disordered breathing, the most common being obstructive sleep apnea. Midface hypoplasia in children with craniosynostosis and glossoptosis in children with Pierre Robin syndrome are well recognized risk factors, but the etiology is often multifactorial and many children have multilevel airway obstruction. We examine the published evidence and explore the current management strategies in these complex patients. Some treatment modalities are similar to those used in otherwise healthy children such as adenotonsillectomy, positive pressure ventilation and in the refractory cases, tracheostomy. However, there are some distinct approaches such as nasopharyngeal airways, tongue lip adhesion, mandibular distraction osteogenesis in children with Pierre Robin sequence, and midface advancement in children with craniosynostoses. Clinicians should have a low threshold for referral for evaluation of sleep-disordered-breathing in these patients.

In Situ and Home Care Nasopharyngeal Intubation Improves Respiratory Condition and Prevents Surgical Procedures in Early Infancy of Severe Cases of Robin Sequence

AIM

To evaluate the clinical outcome of infants with Robin Sequence (RS) and severe respiratory obstruction managed with nasopharyngeal intubation (NPI).

METHODS

This prospective study was conducted with 107 infants with RS admitted to the Hospital for Craniofacial Anomalies of the University of São Paulo (HRAC-USP), from July 2003 to June 2010, diagnosed with severe RS and treated with NPI. The infants were followed up for the first year of life. Clinical findings, morbidity, and mortality were recorded.

RESULTS

Of the 223 infants with RS admitted to the hospital in the period studied, 149 were diagnosed with severe respiratory distress and 107 (71.81%) matched all the inclusion criteria. Of those, 78 (73%) presented Isolated Robin Sequence and 29 (27%) presented other syndromes or anomalies associated with RS. NPI treatment lasted an average of 57 days and the mean hospitalization time was 18 days. Although all infants presented feeding difficulties, 85% were fed orally and only 15% underwent gastrostomy. Morbidity was 14% and no deaths occurred.

CONCLUSIONS

The children treated with the RS treatment protocol adopted at the HRAC-USP had improved respiratory and feeding difficulties, required a shorter hospitalization time, and presented low morbidity and mortality during the first year of life. The general outcome prevented surgical procedures in early infancy.

Semi-automatic volumetric segmentation of the upper airways in patients with pierre robin sequence

Pierre Robin malformation is a rare craniofacial dysmorphism whose pathogenesis is multifactorial. Although there is some agreement in non-invasive treatment in less severe cases, the dispute is still open on cases with severe respiratory impairment. We present a semi-automatic novel diagnostic tool for calculating upper airway volume, in order to eventually address surgery in patients with Pierre Robin Sequence (PRS). Multidetector CT datasets of two patients and two controls were tested to assess the proposed method for ROI segmentation, upper airway volume computation and three-dimensional reconstructions. The experimental results show an irregular pattern and a severely reduced cross-sectional area (CSA) with a mean value of 8.3808 mm(2) in patients with PRS and a mean CSA value of 33.7692 mm(2) in controls (a ΔCSA of about -75%). Moreover, the similarity indexes and sensitivity/specificity values obtained showed a good segmentation performance. In particular, mean values of Jaccard and Dice similarity indexes were 91.69% and 94.07%, respectively, while the mean values of specificity and sensitivity were 96.69% and 98.03%, respectively. The proposed tool represents an easy way to perform a quantitative analysis of airway volume and useful 3D reconstructions.

Impact of sleep and breathing in infancy on outcomes at three years of age for children with cleft lip and/or palate

STUDY OBJECTIVES

To evaluate the relationship between sleep disordered breathing (SDB) in early infancy and outcomes at 3 years of age in children with cleft lip and/or palate (CL/P).

DESIGN

Observational follow-up study.

SETTING

Multidisciplinary CL/P clinic, tertiary centre.

PARTICIPANTS

Children with CL/P who participated in a study of sleep and breathing in infancy.

MEASUREMENTS AND RESULTS

The families of 52 children were approached for this follow-up study. The children underwent neurocognitive (Bayley Scales of Infant and Toddler Development, Third Edition; BSID-III), quality of life (Infant/Toddler Quality of Life Questionnaire; ITQOL), and growth assessments at 3 years. The families of 33 children (66%) completed follow-up at 36.7 ± 1.4 months. The apnea-hypopnea index (AHI) in infancy was 23.9 ± 18.0 events/h. Mean group BSID-III scores fell within the standardized normal range (10 ± 3) for all domains; however, language scores were lower than control children. Quality of life scores and growth parameter z-scores were similar to published control data. PSG variables in infancy showed significant relationships with outcomes at 3 years of age; lower percentage of AS/REM sleep was associated with lower cognition score; more obstructive events were associated with lower global behavior ITQOL score; and higher number of respiratory events in infancy was associated with lower weight z-score.

CONCLUSION

Neurocognition, quality of life, and growth measures from children with CL/P fall within a normal range; however, scores in the language domain are lower than controls. Sleep and respiratory elements of SDB in infancy appear to modify these outcomes at 3 years of age.

Airway considerations in craniofacial patients

Children with syndromic craniosynostosis have an increased risk of airway obstruction. Addressing this issue early in their clinical course helps ensure a safe result. Because of their abnormal airways and a higher risk of sleep-related breathing disorders, regular evaluation of the airway is recommended. An algorithm for evaluation, including sleep study, and management of such children is proposed. Patients with abnormal sleep studies should undergo endoscopy (nasendoscopy or flexible fiberoptic bronchoscopy) to determine the site of the obstruction and then adenotonsillectomy when appropriate. Continuous positive airway pressure, nasopharyngeal airways, or surgery, including osteotomy or even tracheostomy, may be necessary. Regular evaluation of the airway is critical, because the airway status may improve or worsen with growth of the child. Finally, ongoing communication with the craniofacial team allows planning of various procedures in the individual patient with optimal management of the airway.

Percutaneous gastrostomy tubes in children with Pierre Robin sequence: efficacy, maintenance and complications

BACKGROUND

Children with Pierre Robin sequence (PRS) have significant oropharyngeal abnormalities, with respiratory and feeding difficulties. Gastrostomy tubes (G-tube) provide a means for nutrition.

OBJECTIVE

To evaluate the safety and efficacy of percutaneous G-tube insertion in children with PRS.

MATERIALS AND METHODS

Of 120 children with PRS (1996-2009), 40 were referred for G-tube insertion; clinical details were reviewed in 37/40 children (18M, 19F) at three time periods: (1) pre-G-tube insertion, (2) at G-tube insertion, (3) at G-tube removal.

RESULTS

Pre-G-tube: 32/37 were term infants; 5 were preterm; 16/37 children were ≤ 10th weight percentile. At G-tube insertion, mean age was 66 days, mean weight 4.4 kg (1.1-7.0 kg); 19 dropped ≥10 weight percentiles; 12 tolerated nil by mouth; 2/37 were intubated for the procedure. All G-tubes were successfully placed, with five minor technical issues. Early postprocedure, there were eight minor complications and two dislodgements (classified as major). At G-tube removal mean G-tube dwell time was 2 years, with an average of 3.6 maintenance procedures per child, approximately 3 tube changes/1,000 tube days. At G-tube removal, 76% had maintained or increased weight centiles.

CONCLUSION

G-tubes in PRS provide a safe method for nutrition until children feed adequately by mouth.

Controversies in the diagnosis and management of the Robin sequence

The Robin sequence, previously known as the Pierre Robin syndrome, is characterized by the sequence of clinical events that result from a small mandible. The tongue becomes posteriorly displaced (glossoptosis) and obstructs the airway. The obstructing tongue also makes oral feeding difficult and, in severe cases, impossible. Patients with Robin sequence may also present with a cleft palate, although this is not necessary to make the diagnosis. The small mandible either results from an inherent growth problem (genetic or syndromic) or is deformational where intrauterine growth of the mandible is restricted. Conditions of syndromic patients are generally more severe and difficult to treat. The phenomenon of "catch-up" growth is disputed, although it is likely to occur in deformational but not syndromic patients. Patients with Robin sequence are best managed by a multidisciplinary team familiar with the diagnoses and treatment of difficult pediatric airways. Approximately 70% of Robin infants are successfully managed by prone positioning alone. Tracheostomy is necessary in approximately 10% of these patients, especially for subglottic obstructions including laryngomalacia and tracheomalacia. Tracheostomy should be avoided if possible. Treatment of the remaining 20% remains highly contentious. Tongue-lip adhesion, nasopharyngeal airways, and distraction osteogenesis all have strong advocates. Ideally, treatment should be individualized. Patients who will have catch-up growth of the mandible will only need a tongue-lip or nasopharyngeal airway as a temporary measure. Patients who we know will not have catch-up growth will benefit from early distraction osteogenesis.

Neonates with Tongue-Based Airway Obstruction

Objective. In this systematic review, the authors summarize the current evidence in the literature regarding diagnosis, treatment, and long-term outcomes in neonates with tongue-based airway obstruction (TBAO) and assess the level of evidence of included studies.

Data Sources. The terms Pierre Robin syndrome/sequence, micrognathia, retrognathia, and cleft palate were combined with airway obstruction, treatment, tongue-lip plication, and osteogenesis distraction to perform an Ovid literature search, yielding 341 references. The authors excluded references containing patients with isolated choanal/nasal obstruction, patients older than 12 months, and expert opinion papers, yielding 126 articles.

Review Methods. The authors searched 3 electronic databases and reference lists of existing reviews from 1980 to October 2010 for articles pertaining to the diagnosis, treatment, and outcomes of TBAO. Reviewers assigned a level of evidence score based on Oxford’s Centre for Evidence Based Medicine scoring system and recorded relevant information.

Results. Most studies were case studies and single-center findings. The lack of standardization of diagnostic and treatment protocols and the heterogeneity of cohorts both within and between studies precluded a meta-analysis. There was little evidence beyond expert opinion and single-center evaluation regarding diagnosis, treatment, and long-term outcomes of neonates with TBAO.

Conclusions. The variability in the phenotype of the cohorts studied and the absence of standardized indications for intervention preclude deriving any definitive conclusions regarding diagnostic tools to evaluate this patient population, treatment choices, or long-term outcomes. A coordinated multicenter study with a standardized diagnostic and treatment algorithm is recommended to develop evidence for the diagnosis and treatment of neonates with TBAO.

Temporal association of polysomnographic cardiorespiratory events with GER detected by MII-pH probe in the premature infant at term

OBJECTIVES

The aim of the study was to examine temporal association (TA) between polysomnographic cardiorespiratory (CR) events and gastroesophageal reflux (GER) in premature infants with persistent CR events at >39 weeks postmenstrual age and determine whether the use of multichannel intraluminal impedance (MII)-pH probe improves sensitivity of the TA compared with pH probe alone.

PATIENTS AND METHODS

Seven infants born between 24 and 29 weeks' gestational age with persistent CR events at 39 to 48 weeks' postmenstrual age underwent a polysomnography with MII-pH probe. Symptom index (SI) and symptom-associated probability were calculated for diverse types of reflux and CR events. SI and a Fisher exact test with variable association windows were calculated for obstructive apnea (OA). Odds ratios for an OA given a reflux event and for a reflux event given an OA were determined.

RESULTS

With a Fisher exact test, a subject-specific association between MII events and OA was found in the 3 patients who required a fundoplication or had the worse clinical GER. Some level of TA was found with SI and symptom-associated probability in 6 of 7 infants. Association was found for pH > 4 and pH ≤ 4 reflux events. pH-only events with no change of MII had only a limited role in generating CR events.

CONCLUSIONS

TA between CR events and GER was found in a single-subject-level analysis in some infants with persistent CR events at term. This TA suggests a causal relation between CR and reflux events that was further strengthened by the clinical outcomes of each infant.

Treatment Modalities of Infants with Upper Airway Obstruction—Review of the Literature and Presentation of Novel Orthopedic Appliances

Objective

To present a new orthopedic method for treatment of infants with Pierre Robin sequence (PRS) and upper airway obstruction (UAO) as an alternative to other established nonsurgical and surgical techniques such as positioning, nasopharyngeal or endotracheal intubation, tongue-lip adhesion, extension, distraction, or tracheostomy.

Design

Review of the literature and presentation of novel orthopedic appliances.

Setting

Department of Orthodontics, Dental Clinic, Medical Faculty of the University of Wuerzburg, Germany, Department and Clinic of Pediatrics, Medical Faculty of the University of Wuerzburg, Germany, 2005 to 2008.

Patients

Seven patients with significant respiratory and feeding difficulties between 0 and 6 months of age. Both patients with nonsyndromic PRS and patients with syndromic PRS were included.

Interventions

The type of respiratory tract obstruction was defined by nasopharyngoscopy. Patients with type 1 obstruction received a plate with an epiglottic spur; whereas, patients with obstruction type 2, 3, or 4 received a plate with a pharyngeal tube.

Results

All patients were successfully treated with orthopedic appliances alone. Under plate therapy they showed good oxygen saturation and could consequently be better nourished orally.

Conclusions

The presented novel method is a noninvasive technique in treatment of infants with UAO.

Clinical and Fiberoptic Endoscopic Evaluation of Swallowing in Robin Sequence Treated with Nasopharyngeal Intubation: The Importance of Feeding Facilitating Techniques

Objective

To evaluate oral feeding capacity, the swallowing process, and risk for aspiration, both clinically and during fiberoptic endoscopic evaluation of swallowing, in infants with isolated Robin sequence treated exclusively with nasopharyngeal intubation and feeding facilitating techniques.

Design

Longitudinal and prospective study.

Setting

Hospital de Reabilitação de Anomalias Craniofaciais, University of São Paulo, Bauru, Brazil.

Patients

Eleven infants with isolated Robin sequence, under 2 months of age, treated with nasopharyngeal intubation.

Interventions

Feeding facilitating techniques were applied in all infants throughout the study period. The infants were evaluated clinically and through fiberoptic endoscopic evaluation of swallowing at first, second, and, if necessary, third week of hospitalization (T1, T2, T3). The mean volume of ingested milk was registered during clinical evaluation, and events were registered during feeding.

Results

The respiratory status of all infants was improved after nasopharyngeal intubation; 72% of them presented risk for aspiration during fiberoptic endoscopic evaluation of swallowing at T1. This risk was less frequent when thickened milk was given to the infants and at subsequent evaluations (T2 and T3).

Conclusions

Nasopharyngeal intubation aids in stabilizing the airway in isolated Robin sequence, but it does not relate directly to feeding. The risk for aspiration was present in most of the infants, mainly during the first week of hospitalization, and improved within a few weeks, after the use of feeding facilitating techniques.

Airway Management for Infants with Severe Micrognathia Having Mandibular Distraction Osteogenesis

We retrospectively reviewed the charts of seven neonates and infants with severe micrognathia and upper airway obstruction who underwent mandibular distraction osteogenesis as an alternative to long-term tracheostomy at the Children's Hospital at Westmead, Sydney, from 2004 to 2007.

All patients required a variety of airway interventions at an early age and had poor feeding or failure to thrive. These children had other anomalies and required many investigations and procedures and presented repeated airway challenges for the anaesthetist. The mean number of anaesthetics per child in this series was 6.7 (range 4 to 13).

Under anaesthesia, four patients had grade 4 laryngoscopy, one was grade 3 but two were only grade 2. Patients with a preoperative grade 4 laryngoscopy were very likely to need fibreoptic endotracheal intubation. Duration of intubation after surgery for mandibular distraction was a mean of 8.17 days (range 1 to 19). Three were extubated in the operating theatre and three in intensive care. Five patients had an improved laryngoscopy grade after completion of mandibular distraction and one remained grade four. The remaining patient had a tracheostomy from birth.

Cleft lip and/or palate and breathing during sleep

Cleft of the lip and/or palate (CL/P) is a common defect which is associated with changes in facial structures and a smaller upper airway. As a result, infants and children with CL/P have an increased risk of sleep disordered breathing (SDB). This paper will review the anatomical and functional factors which place infants and children with CL/P at increased risk of SDB as well as review the literature which defines the magnitude of this risk. The information available on treatment of SDB in infants and children with CL/P will be presented. Finally, outstanding issues relevant to SDB in children with CL/P are discussed with direction for future research.

Gastroesophageal reflux in severe cases of Robin sequence treated with nasopharyngeal intubation

OBJECTIVE

To study the prevalence of abnormal gastroesophageal reflux in infants with Robin sequence who had severe respiratory obstruction treated with nasopharyngeal intubation and to evaluate the efficacy of nonsurgical treatment.

DESIGN

Longitudinal prospective study.

SETTING

Hospital de Reabilitação de Anomalias Craniofaciais, University of São Paulo, Brazil.

PATIENTS

Twenty infants with severe isolated Robin sequence treated with nasopharyngeal intubation.

INTERVENTIONS

We performed 24-hour esophageal pH monitoring on each child at 2, 4, and 6 months of age. Respiratory and feeding status were evaluated. We considered abnormal gastroesophageal reflux as reflux index values above the 95th percentile of the Vandenplas reference for normal children.

RESULTS

The prevalence of reflux index above the 95th percentile at the first exam was 6/20, a value significantly higher than the reference (5/103, p < .01). At the second and third exams, reflux index values were decreased. Ninety percent of the infants showed improvement of respiratory difficulty and developed oral feeding capacity.

CONCLUSIONS

The prevalence of abnormal gastroesophageal reflux is higher in infants with severe cases of Robin sequence than in normal infants. Nonsurgical procedures improved respiratory and feeding difficulties of most of these infants.

Cognitive and psychosocial development of children with Pierre Robin sequence

AIM

It is unclear whether cognitive impairment in Pierre Robin sequence (PRS) results from a primary disturbance affecting both the brain and the mandible or from recurrent upper airway obstruction (UAO). If the latter were true, cognitive impairment should be preventable by early treatment of UAO. We wanted to determine the cognitive and psychosocial outcome of children with PRS treated with a new device aimed at relieving UAO in infancy (pre-epiglottic baton plate).

METHODS

Thirty-four children with PRS and 34 healthy controls aged 4-11 years completed the Kaufman-Assessment Battery for Children (K-ABC) and a self-concept inventory. Parents rated their children's emotional and behavioural problems. Multi- and univariate analyses of covariance were performed, controlling for gender, age, parental education, family income and parental depression.

RESULTS

The cognitive development of the PR children was within the reference range. Compared to healthy children, however, the children with PRS performed significantly poorer. There were no significant differences concerning self-concept, emotional or behavioural problems.

CONCLUSION

These children with non-syndromic PRS who had received treatment of UAO in infancy performed worse in the K-ABC. However, this did not reflect a major cognitive impairment.

The effect of glossopexy on weight velocity in infants with Pierre Robin syndrome

AIM

In infants with Pierre Robin syndrome (PRS), mandibular distraction may be more advantageous than glossopexy as it not only relieves oropharyngeal airway obstruction but also reverses body growth retardation. Because no data are available on body weight velocity after glossopexy, we assessed longitudinally the body weight velocity in a cohort of children undergoing glossopexy.

METHODS

The records of 48 infants with PRS undergoing glossopexy after unsuccessful nonoperative treatment between 1981 and 2005 were reviewed. Weight measurements were analyzed at 4 time-points: at birth, on admission for glossopexy, on admission for lysis of lip-tongue adhesion (TLA), and at follow-up. Weight velocity was assessed using Tanner's tables.

MAIN RESULTS

Adhesion dehiscence occurred in 9 patients (18.7%). Lip-tongue adhesion resolved airway compromise in 36 infants (75%). Release of TLA was accomplished in 34 patients. Data on weight velocity from birth to follow-up (mean, 5.57 +/- 0.59 years) were available for 31 patients. After glossopexy, mean body weight increased from the 9.7 +/- 2.6th to the 17.5 +/- 4.6th percentile (P > .05), whereas mean weight velocity increased from the 19.1 +/- 4.9th to the 74.2 +/- 4.7th percentile (P < .001). No temporal correlation was found between glossopexy and oropharyngeal dysphagia.

CONCLUSION

In infants with PRS, glossopexy is a valid alternative to mandibular distraction because it does not cause decline in body growth.

Home management of upper airway obstruction in Pierre Robin sequence using a nasopharyngeal airway

OBJECTIVE

This unit has reported management of infants with Pierre Robin Sequence (PRS) and upper airway obstruction using nasopharyngeal airways and nutritional support until enough growth takes place for the infant to thrive. There was a mean hospital stay of 60 days. This long in-patient stay prompted review of our management protocols and consideration of treatment at home. This paper reports our experience of managing infants with PRS at home using a nasopharyngeal airway and nasogastric feeding tube and reviews whether such management reduces in-patient stay while remaining safe and effective.

DESIGN

Retrospective review of cases referred over a 3.5-year period. Comparison is made with the unit's previously published results.

PATIENTS

Thirteen PRS infants were referred to the West Midlands Regional Cleft service and required transfer to Birmingham Children's Hospital for specialist assessment and airway control.

INTERVENTIONS

The parents of 12 infants underwent training to manage the airway and feeding tube. Treatment then continued at home.

OUTCOME MEASURES

In-patient episode, rate of weight gain, and complication rate were used.

RESULTS

The median hospital stay was 19.5 days compared to 54 days previously. The median rate of weight gain was 34 g/d. There were no complications or readmissions.

CONCLUSION

This series demonstrates the revised management protocol followed has reduced in-patient stays and remained effective, with infants continuing to thrive after discharge home, and has a low complication rate.

Mandibular morphology and growth with and without hypodontia in subjects with Pierre Robin sequence

INTRODUCTION

Mandibular micrognathia is the hallmark of Pierre Robin sequence (PRS). A high prevalence of mandibular hypodontia has been reported in subjects with PRS. The hypothesis of this study is that the morphology of the mandible in subjects with PRS and mandibular hypodontia is different from that in subjects with PRS but without mandibular hypodontia.

METHODS

The study was conducted at the craniofacial center of The Hospital for Sick Children in Toronto. The study sample comprised 16 caucasian children with nonsyndromic PRS (7 boys, 9 girls) with mandibular hypodontia and 18 white children with nonsyndromic PRS (6 boys, 12 girls) without hypodontia. Longitudinal lateral cephalograms were available before orthodontic treatment (T1; mean age, 11.7 years) and after orthodontic treatment but before orthognathic surgery (T2; mean age, 16.6 years). A new, customized cephalometric analysis with additional landmarks and measurements to study mandibular morphology was performed. Differences in measurements were studied by using analysis of variance adjusted for age and sex.

RESULTS

Cephalometric measurements were smaller in the group with mandibular hypodontia at T1: mandibular length (3.36 mm, P = .04), ramal length (2.78 mm, P = .04), posterior facial height (3.97 mm, P = .03), and mandibular molar eruption (1.96 mm, P = .02). At T2, the differences increased: mandibular length (4.56 mm, P = .02), ramal length (4.04 mm, P = .002), posterior facial height (5.98 mm, P = .001), and mandibular molar eruption (2.08 mm, P = .04). Comparison of growth increments between the 2 groups from T1 to T2 showed a greater cranial base deflection increment in the group with mandibular hypodontia (0.88 degrees, P = .02) and a larger posterior facial height increment in the group without mandibular hypodontia (2.02 mm, P = .04).

CONCLUSIONS

Children with nonsyndromic PRS with mandibular hypodontia had smaller mandibles than children with nonsyndromic PRS and normal complements of mandibular teeth. Their patterns of growth did not improve during adolescence, and the magnitude of differences increased.

Robin sequence: a retrospective review of 115 patients

OBJECTIVES

Review a large series of patients with Robin sequence to document the incidence of (1) associated syndromic diagnoses; (2) co-morbid conditions; (3) frequency and type of operative management for airway compromise and feeding difficulties; and (4) possible differences in treatment between syndromic and nonsyndromic infants.

METHODS

Retrospective case-review of 115 patients with Robin sequence managed between 1962 and 2002 at two tertiary-care teaching hospitals for evaluation of demographic information, clinical findings, and treatment interventions.

RESULTS

Fifty-four percent (N=63) of patients were nonsyndromic. Syndromic patients included: Stickler syndrome (18%), velocardiofacial syndrome (7%), Treacher-Collins (5%), facial and hemifacial microsomia (3%), and other defined (3.5%) and undefined (9%) disorders. There was no statistical difference between the syndromic and nonsyndromic patients with regard to need for operative airway management (Fisher's exact test, p=0.264). Forty-two percent of patients required a feeding gastrostomy tube to correct feeding difficulties. Patients with a syndromic diagnosis were more likely to be developmentally delayed. Fifty-one (44%) patients underwent operative airway management: 61% underwent tongue-lip adhesion and 39% underwent tracheotomy. Fifteen percent of patients initially had tongue-lip adhesion subsequently required tracheotomy. While the preferred treatment for respiratory compromise differed between the two institutions, the percentage of patients requiring operative intervention was similar.

CONCLUSIONS

The pathogenesis of Robin sequence is multifactorial and syndromic in nearly half of the patients. Operative treatment of respiratory failure was required in 44% of infants; the rate was similar in both hospitals. The operative approach differed significantly between the institutions, however, based on the philosophy and training of the managing surgical specialty. Co-morbid factors such as baseline cardiopulmonary and neurologic status did not play a significant role in surgical decision making.

Neonatal Distraction Surgery for Micrognathia Reduces Obstructive Apnea and the Need for Tracheotomy

The objective of the study was to assess the effectiveness of neonatal mandibular distraction in treatment of obstructive sleep apnea in the perinatal period in preventing a tracheotomy. This was a prospective study of 17 infants at two centers with severe micrognathia who demonstrated obstructive sleep apnea refractory to conservative therapy. Age at surgery varied from 5 to 120 days. Distraction was performed at a rate of 2 mm/d. After distraction, callus consolidation was allowed for 4 to 6 weeks, and the device was then removed. Each child underwent a three-dimensional computed tomography scan before surgery and approximately 3 months after surgery. Of the 17 patients, 14 successfully underwent extubation and demonstrated significant improvement in the obstructive sleep apnea. Postoperative horizontal ramus length increased from 23.3 to 34.8 mm after surgery. Mean maxillary mandibular discrepancy was 8.28 mm before surgery and 2.2 mm after surgery. Ten infants who underwent pre- and postoperative polygraphic studies showed improvement in obstructive apnea. Three patients had postoperative polysomnographic studies only; the results were also within the normal range. The mean follow-up interval was 16.5 months (range: 8-48 months). Neonatal distraction is an effective method for treatment of micrognathia with obstructive sleep apnea in the perinatal period in preventing a tracheotomy.

Congenital upper airway obstruction

Most causes of upper airway obstruction are rare in the neonatal period and during infancy. They may, however, cause major respiratory problems either initially or during the first few weeks of life. It is important to recognise these problems at an early stage so that appropriate measures to overcome airway obstruction can be initiated, thus avoiding significant hypoxia-related complications. Specific treatment includes the use of nasal stents, a nasopharyngeal airway or, in severe cases, tracheostomy. Many such infants have associated feeding problems secondary to the airway obstruction and associated swallowing difficulties, which can lead to recurrent aspiration. The anomalies seen in clinical practice are best classified anatomically. Treatment is aimed at overcoming the mechanical effects of airway obstruction and maximising nutritional input so as to promote growth of the airway and long-term recovery of normal upper airway function.

Die Tübinger Gaumenplatte — Ein innovatives Therapiekonzept bei Pierre-Robin-Sequenz

Infants with Pierre-Robin sequence (PRS) may suffer severe upper airway obstruction resulting in hypoxemia that is difficult to treat. We are currently evaluating a new therapeutic approach involving an oral appliance that widens the pharynx by pulling the base of the tongue forward using a preepiglottic baton. Here we present a patient treated with this device who showed a decrease in his desaturation index from 50 to < 1.

Effective management of the airway in the Pierre Robin syndrome using a modified nasopharyngeal tube and pulse oximetry

Pierre Robin syndrome is a rare condition, first described by the French stomatologist, Pierre Robin in 1923. The severity of the syndrome varies widely, and associated upper airway obstruction is the most difficult problem to overcome. We present a case in which the airway was successfully managed with a modified naso-pharyngeal tube in addition to pulse oximetry. We also present a literature review discussing management of the airway in the Pierre Robin syndrome. The simple technique presented allows earlier patient discharge with home monitoring equipment.

Management of infants with Pierre Robin sequence

OBJECTIVE

Several methods of treating babies with Pierre Robin sequence have been described since the condition itself was first documented in 1923. The main aim of treatment has been to relieve upper airway obstruction. Treatment methods used range from positioning of the baby to invasive surgery. The aim of this article was to describe the assessment, treatment, and monitoring methods used for babies referred with Pierre Robin sequence (PRS).

SETTING/PATIENTS

From December 1995 to May 2000, 22 consecutive patients were admitted to Birmingham Children's Hospital with PRS. Their airway and nutritional status were assessed and continuously monitored.

INTERVENTIONS

Treatment concentrated on the relief of airway obstruction with a nasopharyngeal airway (NPA) and nutritional support of the babies until they grew out of their respiratory and feeding difficulties.

MAIN OUTCOME MEASURES

Outcome measures were oxygen saturation, growth of the babies, and the need for surgery.

RESULTS

All babies were managed successfully with an NPA and nutritional support. No baby required surgery, and the majority showed good weight gain.

CONCLUSION

Relieving airway obstruction by NPA is an effective and safe treatment for babies with PRS until they have grown out of their respiratory and feeding difficulties. It avoids the need for surgery and can be used on neonatal wards using the monitoring described.

Motor dysfunction of the upper digestive tract in Pierre Robin sequence as assessed by sucking-swallowing electromyography and esophageal manometry

OBJECTIVES

To evaluate motor dysfunction in infants with Pierre Robin sequence (PRS) who manifest upper airway obstruction and congenital dysphagia.

STUDY DESIGN

Term infants (n = 28) with nonsyndromic PRS were studied between days 15 and 45. Sucking-swallowing electromyography was used to evaluate suction and coordination between the oral and pharyngeal phases of swallowing. Esophageal manometry was used to study the lower esophageal sphincter, esophageal body, and upper esophageal sphincter functions. Manometry results were compared with those of 16 infants with gastroesophageal reflux disease (GERD).

RESULTS

Electromyography showed incoordination of sucking and swallowing in 24 of 28 patients. The disorder was mild in 6, moderate in 6, and severe in 12 patients. All patients showed manometry disturbances: incomplete or asynchronous lower sphincter relaxation (15), multipeaked esophageal body waves (17), very high amplitude waves (14), and asynchronous upper sphincter relaxation (19). The frequency of disturbances and mean resting pressures of both lower and upper sphincters were significantly higher than GERD patients.

CONCLUSION

In Pierre Robin sequence, sucking-swallowing electromyography and esophageal manometry reveal dysfunction in the motor organization of the tongue, the pharynx, and the esophagus.

Management of acute hypoxemia during flexible bronchoscopy with insertion of a nasopharyngeal tube in lung transplant recipients

STUDY OBJECTIVES

To assess the utility of nasopharyngeal tube insertion in the management of hypoxemia during flexible bronchoscopy (FB) in lung transplant recipients, and to determine the incidence and risk factors of upper-airway obstruction (UAO) leading to significant hypoxemia during FB.

SETTING

Heart-lung transplant unit of a university hospital.

PATIENTS AND METHODS

Ninety-six lung transplant recipients (47 men and 49 women; mean +/- SD age, 41.4 +/- 13.1 years) underwent 714 FB procedures from January 1997 to May 2000.

INTERVENTION

A fall in oxygen saturation (< or = 90%) in patients receiving 6 L/min of oxygen via nasal prongs was treated with insertion of a nasopharyngeal tube, continued oxygen supplementation, and withdrawal of the bronchoscope to the trachea. If oxygen desaturation persisted at < 90% despite additional oxygen administration via a 7F catheter placed either just above the larynx or in the proximal trachea, the bronchoscope was withdrawn, reversal of sedation was administered, and bag and mask ventilation was instituted until satisfactory spontaneous ventilation was achieved.

RESULTS

Forty-six patients (47.9%) were treated with nasopharyngeal tube insertion on 102 occasions at a mean duration of 168 +/- 178 days after lung transplantation. In 90 of 102 procedures (88.2%), significant hypoxemia due to UAO was successfully treated with nasopharyngeal tube insertion. The mean oxygen saturation after nasopharyngeal tube insertion was 97 +/- 3%. Male gender, increase in body mass index after lung transplantation, and presence of obstructive sleep apnea were significant factors associated with the need for nasopharyngeal tube insertion during FB in lung transplant recipients.

CONCLUSIONS

Significant oxygen desaturation during FB in lung transplant recipients is mainly due to UAO. Insertion of a nasopharyngeal tube is a novel and a highly effective approach to the management of acute hypoxemia during FB.

Glossopexy as an alternative to aortopexy in infants with repaired esophageal atresia and upper airway obstruction

BACKGROUND/PURPOSE

Clinical manifestations of airway obstruction in infants with repaired esophageal atresia or tracheoesophageal fistula (EA/TEF) are attributed conventionally to tracheomalacia. In the current study, the authors tested the hypothesis that a retrodisplacement of the tongue (glossoptosis), by causing a functional upper airway obstruction (obstructive apnea/hypopnea), may play a role in the pathogenesis of the respiratory problems.

METHODS

The records of 5 infants with repaired EA/TEF and respiratory symptoms treated by glossopexy, which serves to anchor the tongue forward, were reviewed. Prompt improvement after glossopexy in clinical manifestations, in blood gas exchange, and in weight velocity was used to establish a primary cause-effect relationship between glossoptosis and respiratory problems.

RESULTS

Before glossopexy, all infants presented with severe respiratory distress. Three infants had life-threatening events requiring recurrent or chronic airway intubation. Four infants had severe tracheomalacia, diagnosed at bronchoscopy. All infants presented obstructive apnea/hypopnea with desaturation. Body weight was below the third percentile in all infants. After glossopexy, 3 presented a marked clinical improvement associated with significant increase in mean oxygen saturation (88% +/- 0.4 SE v 95% +/- 0.3 SE; P <.001). In another infant, glossopexy allowed permanent decannulation but did not relieve the problem during crying or excitement when obstructive hypopnea with desaturation required supplemental oxygen. After glossopexy and despite subsequent aortopexy, the last infant could not be extubated and died later of mycotic sepsis. Autopsy results showed a vascular ring. In the 4 surviving infants, glossopexy was followed promptly by significant catch-up growth and subsequent normal growth velocity (P =.03).

CONCLUSIONS

Present findings support the concept that, in some infants with EA/TEF, respiratory problems are mainly caused by recurrent obstructive apnea/hypopnea, which may be treated successfully by lip-tongue adhesion procedures. Severe airway obstruction, not relieved by glossopexy, requires aortopexy to reduce the respiratory load imposed by tracheomalacia.

Clinical experience with infants with Robin sequence: a prospective study

OBJECTIVE

To study the clinical course of patients with Robin sequence (RS) during the first 6 months of life.

DESIGN

A longitudinal prospective study of children with RS.

SETTING

Hospital de Reabilitação de Anomalias Craniofaciais, Universidade de São Paulo, Bauru-SP, Brazil, 1997 and 1998.

PATIENTS

Sixty-two children were studied from hospital admission to 6 months of age. Thirty-three (53.2%) presented with probable isolated RS (PIRS), 25 (40.3%) presented with syndromes or other malformations associated with RS, and 4 (6.5%) presented with RS with neurological involvement.

INTERVENTIONS

The type of respiratory tract obstruction was defined by nasopharyngoscopy. The patients with type 1 and type 2 obstruction underwent nasopharyngeal intubation (NPI), and glossopexy was indicated in patients with type 1 obstruction who did not show clinical improvement with this procedure. Tracheostomy was indicated in patients with type 2 obstruction who did not show a good course after NPI, in patients with type 1 obstruction who did not show good course after glossopexy, and in patients with type 3 and type 4 obstruction.

RESULTS

Prone position treatment (PPT) or NPI was the definitive treatment in 25 cases (75.8%) of PIRS and in 13 cases (52%) of syndromes or other malformations. Among the children with type 1 obstruction, 24 (51.1%) were submitted exclusively to PPT and 12 (25.5%) to NPI. With the type 2 groups, only one (12.5%) received PPT, and three (37.5%) were treated exclusively with NPI. All 15 infants treated exclusively with NPI (24.4%) presented with good weight, length, and neuromotor development.

CONCLUSIONS

Most patients with PIRS and type 1 obstruction improved without surgical intervention. NPI should be the initial treatment in all patients with RS with type 1 and type 2 obstruction who present with important respiratory and feeding difficulties.

Oesophageal perforation presenting as oesophageal atresia in a premature neonate following difficult intubation

Iatrogenic oesophageal perforation in neonates is well recognized in the medical and surgical literature with intubation injury listed as a possible contributing mechanism besides nasogastric tube placement and suctioning. Diagnosis can be difficult and sometimes confused with other entities. With early diagnosis, nonsurgical management often leads to complete resolution in neonates. We report the case of a 1-day-old premature neonate who was brought to the operating room with the preliminary diagnosis of proximal oesophageal atresia with stump perforation and distal tracheo-esophageal fistula. His intubation for respiratory distress at birth had been difficult due to Pierre-Robin sequence with micrognathia. Oesophagoscopy in the operating room revealed a patent oesophagus but perforations in the pharynx and in the proximal oesophagus with the nasogastric tube entering the pharyngeal perforation. Oesophageal perforation and the limitations of the difficult airway algorithm in small neonates are discussed.

Late presentation of upper airway obstruction in Pierre Robin sequence

A retrospective review was carried out of 11 consecutive patients with the Pierre Robin sequence referred to a tertiary paediatric referral centre over a five year period from 1993 to 1998. Ten patients were diagnosed with significant upper airway obstruction; seven of these presented late at between 24 and 51 days of age. Failure to thrive occurred in six of these seven infants at the time of presentation, and was a strong indicator of the severity of upper airway obstruction. Growth normalised on treatment of the upper airway obstruction with nasopharyngeal tube placement. All children had been reviewed by either an experienced general paediatrician or a neonatologist in the first week of life, suggesting that clinical signs alone are insufficient to alert the physician to the degree of upper airway obstruction or that obstruction developed gradually after discharge home. The use of polysomnography greatly improved the diagnostic accuracy in assessing the severity of upper airway obstruction and monitoring the response to treatment. This report highlights the prevalence of late presentation of upper airway obstruction in the Pierre Robin sequence and emphasises the need for close prospective respiratory monitoring in this condition. Objective measures such as polysomnography should be used, as clinical signs alone may be an inadequate guide to the degree of upper airway obstruction.

[Obstructive sleep apnea syndrome in infants and children]

Obstructive sleep apnea syndrome (OSAS) is characterized by prolonged, generally partial, upper airway obstruction associated with hypoxemia and/or hypercapnia. Main etiological factors include hypertrophy of the tonsils and adenoids, craniofacial abnormalities with reduction in the upper airway caliber, abnormality of neural upper airway control, or a combination of these factors. Symptoms depend on age, but they always include snoring and breathing difficulties during sleep. Diagnosis of OSAS must be established early in order to prevent complications. It is suspected on history, physical examination and investigative confrontation such as nasofibroscopy and imaging. Polysomnography is the gold standard for diagnosis, scoring of the obstruction and distinction between primary snoring and obstructive breathing. Adenotonsillectomy is an effective therapy. For selected patients, craniofacial surgery may be helpful. Some children require continuous positive airway pressure or the nasopharyngeal tube. Tracheotomy is rarely indicated.

Treacher Collins syndrome with acute airway obstruction

Treacher Collins syndrome presents with cranio-facial deformities of variable expressions and severity, but rarely is it associated with acute airway obstruction of such severity that it necessitates surgical intervention. The authors describe their experience with such a neonate, who presented with acute airway obstruction successfully managed with a tracheostomy. The relevant English literature is reviewed.

Naso-oesophageal probes decrease the frequency of sleep apnoeas in infants

The objective of the study was to determine whether a naso-oesophageal probe modifies sleep and cardiorespiratory patterns in infants with repeated obstructive apnoeas. Two polygraphic recording sessions were conducted in random order for 2 nights on 35 infants suspected to have repeated obstructive sleep apnoeas. One sleep study was performed with a pH probe inserted through the nasal passage down to the distal portion of the oesophagus. The other session was conducted without any naso-oesophageal probe (the baseline study). For the 25 infants who presented repeated obstructive apnoeas during baseline studies, the presence of the probe was associated with a small, but significant, decrease in the number of central apnoeas (median frequency of 18.5 apnoeas per hour without a probe; 16.1 per hour with the probe; P=0.040), and obstructive apnoeas (median of 1.9 apnoeas per hour without a probe; 0.6 per hour with the probe; P=0.016). The presence of the probe was also associated with a small increase in percentage non-rapid eye movement (NREM) sleep frequency. The changes were statistically significant only for infants who had no obstructive apnoea during baseline studies (29 vs. 31%). The presence of a naso-oesophageal probe significantly modifies the infants' respiratory characteristics during sleep. These findings should be considered when reporting and interpreting sleep studies in infants.

A modified nasopharyngeal tube to relieve high upper airway obstruction

Infants with high upper airway obstruction (UAO) are managed with a variety of techniques to relieve their UAO. Among these techniques, the least invasive and safest is the nasopharyngeal tube (NPT). However, the traditional NPT is not always satisfactory, and tracheostomies need to be done. We recently described a modified NPT technique that, in contrast to the traditional tube, does not add airway dead space and resistance, is easy to use, is well-tolerated, has proven highly successful, and allows the simultaneous use of oxygen nasal prongs. This modified NPT has many advantages over the traditional NPT as a temporary management of high UAO that resolves with growth of the infant. This report highlights the respiratory care of 10 infants with high UAO (Pierre Robin syndrome, Down syndrome, Goldenhar syndrome, isolated microngathia, and idiopathic hypotonia) who were managed with a modified NPT. The modified NPT described potentially reduces the need for surgical intervention to relieve high UAO in infants.

Modified nasopharyngeal tube for upper airway obstruction

A modified nasopharyngeal tube is described that does not add airway dead space and resistance, is well tolerated, highly successful, and allows simultaneous use of oxygen prongs. This potentially reduces the need for surgical intervention to relieve high upper airway obstruction from Pierre-Robin syndrome and other causes.

Questionnaire evaluation of feeding methods for cleft lip and palate neonates

A questionnaire evaluation was undertaken of feeding methods used by the mothers of 25 neonates with cleft lip and/or palate. Most parents had problems feeding their babies, both with the quantity of food taken and especially with the time taken to feed; even after a period of 2 months over a quarter were still having problems with the quantity of feed and a third had not established a regular feeding pattern. Just over a half needed to change the feeding method from the one with which they started. Twelve of the 25 mothers tried to breast-feed but none of them was successful. The Haberman feeder was the most popular, being used by 18 mothers. An acrylic feeding plate was considered to be helpful by 6 of 11 mothers of babies with complete clefts but by only 1 of 9 mothers of babies with secondary palate clefts. Almost all the mothers were dissatisfied with the information they had received while in hospital and with the back-up when they went home.
