Prevalence, demographics, and complications of cleft palate surgery

Comorbidity and Operative Time are Stronger Predictors than Age for Palatoplasty Adverse Airway Events, A NSQIP-P Study of 6668 Cases

BACKGROUND

Adverse airway events (AAEs) are rare but devastating complications following palatoplasty. The purpose of this study is to evaluate patient risk factors for their effect on these complications. We hypothesize that prolonged operative time and the presence of multiple medical comorbidities are risk factors for AAEs.

DESIGN

Retrospective cohort study.

SETTING

Participant hospitals in the Pediatric American College of Surgeons National Surgical Quality Improvement Program year 2016-2019.

PATIENTS

Cases of palatoplasty in children under 3 years of age.

OUTCOMES

Adverse airway events including postoperative reintubation or any requirement of postoperative mechanical ventilation.

RESULTS

A total of 6668 patients met inclusion criteria. The median operative time was 126 min (IQR 82). AAEs were identified in 107 (1.6%) patients. The incidence of risk factors was found to increase with age and AAEs were more prevalent in younger and older patients. Although patients in the older age groups had significantly higher burden of comorbidities, differences in age were not independently associated with AAEs. Following multivariable logistic regressions, operative times greater than 2 h, ASA class ≥3, >3 medical comorbidities, and black race were found to be significant independent risk factors.

CONCLUSIONS

In this large, retrospective database study in palatoplasty, increased operative time, ASA classification ≥3, multiple comorbidities, and black race were independently associated with AAEs.

Does tranexamic acid effectively minimise blood loss in cleft palate repair? A rigorous assessment through comprehensive systematic review and meta-analysis

Cleft palate repair is a common reconstructive procedure that can involve significant blood loss. Tranexamic acid (TXA) has been proposed to minimise blood loss during various surgical procedures, but its effectiveness in cleft palate repair remains unclear. This systematic review and meta-analysis aimed to assess the effectiveness of TXA to reduce postoperative blood loss. Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a comprehensive search across multiple databases, including PubMed, Cochrane, and Web of Science, to identify relevant studies published up to September 2023. Only randomised controlled trials (RCTs) were included. Primary outcomes measured were total blood loss, transfusion rates, and postoperative complications. We identified four relevant RCTs, which included 275 cleft palate patients with a mean (range) age of 28.7 (6-65) months. The pooled analysis found no significant difference in duration of surgery (MD -18.40 minutes, p = 0.09), preoperative haemoglobin (MD 0.46 g/dl, p = 0.27), or postoperative haemoglobin (MD 0.07 g/dl, p = 0.86) between TXA and control groups. Intraoperative blood loss was lower with TXA, but with TXA, the difference was not statistically significant (MD -16.63 ml, p = 0.15). TXA significantly improved surgical field visibility (p = 0.004). No adverse events occurred with its use. While no significant differences were found in surgical outcomes with TXA, surgical field visibility significantly improved, and TXA showed a promising safety profile. Larger and higher-quality RCTs are still needed to validate these preliminary findings before TXA can be considered as a standard treatment.

Healthcare use and direct medical costs in a cleft lip and palate population: an analysis of observed and protocolized care and costs

This study was performed to describe observed healthcare utilization and medical costs for patients with a cleft, compare these costs to the expected costs based on the treatment protocol, and explore the additional costs of implementing the International Consortium for Health Outcomes Measurement (ICHOM) Standard Set for Cleft Lip and Palate (CL/P). Forty patients with unilateral CL/P between 0 and 24 years of age, treated between 2012 and 2019 at Erasmus University Medical Center, were included. Healthcare services (consultations, diagnostic and surgical procedures) were counted and costs were calculated. Expected costs based on the treatment protocol were calculated by multiplying healthcare products by the product prices. Correspondingly, the additional expected costs after implementing the ICHOM Standard Set (protocol + ICHOM) were calculated. Observed costs were compared with protocol costs, and the additional expected protocol + ICHOM costs were described. The total mean costs were highest in the first year after birth (€5596), mainly due to surgeries. The mean observed total costs (€40,859) for the complete treatment (0-24 years) were 1.6 times the expected protocol costs (€25,198) due to optional, non-protocolized procedures. Hospital admissions including surgery were the main cost drivers, accounting for 42% of observed costs and 70% of expected protocol costs. Implementing the ICHOM Standard Set increased protocol-based costs by 7%.

Revision Palate Surgery

Oronasal fistulae and velopharyngeal insufficiency are common and interdependent complications after cleft palate surgery. Bone grafting can complement cleft habilitation. Early identification and intervention are vital for optimal outcomes. Collaboration with experienced healthcare professionals is crucial to develop a comprehensive treatment plan which considers speech therapy, prosthetic devices, and surgery. This article aims to review the current literature on the management of VPI and oronasal fistulae following cleft palate surgery and additionally highlight the role of alveolar bone grafting to improve outcomes for these patients.

Full-Thickness Oral Mucoperiosteal Defects: Challenges and Opportunities

Regenerative engineering strategies for the oral mucoperiosteum, as may be needed following surgeries, such as cleft palate repair and tumor resection, are underdeveloped compared with those for maxillofacial bone. However, critical-size tissue defects left to heal by secondary intention can lead to complications, such as infection, fistula formation, scarring, and midface hypoplasia. This review describes current clinical practice for replacing mucoperiosteal tissue, including autografts and allografts. Potentially paradigm-shifting experimental regenerative engineering strategies for mucoperiosteal wound healing, such as hybrid grafts and engineered matrices, are also discussed. Throughout the review, the advantages and disadvantages of each replacement or regeneration strategy are outlined in the context of clinical outcomes, quality of life for the patient, availability of materials, and cost of care. Finally, future directions for research and development in the area of mucoperiosteum repair are proposed, with an emphasis on identifying globally available and affordable solutions for promoting mucoperiosteal regeneration. Impact statement Unassisted oral mucoperiosteal wound healing can lead to severe complications such as infection, fistulae, scarring, and developmental abnormalities. Thus, strategies for promoting wound healing must be considered when mucoperiosteal defects are incident to oral surgery, as in palatoplasty or tumor resection. Emerging mucoperiosteal tissue engineering strategies, described in this study, have the potential to overcome the limitations of current standard-of-care donor tissue grafts. For example, the use of engineered mucoperiosteal biomaterials could circumvent concerns about tissue availability and immunogenicity. Moreover, employment of tissue engineering strategies may improve the equity of oral wound care by increasing global affordability and accessibility of materials.

Safety and Efficacy of Single-Dose Ketorolac for Postoperative Pain Management After Primary Palatoplasty: A Prospective Cohort Study With Historical Controls

OBJECTIVE

To analyze safety and efficacy of single-dose ketorolac after primary palatoplasty (PP).

DESIGN

Consecutive cohort of patients undergoing PP, comparing to historical controls. Setting: A large academic children's hospital.

PATIENTS, PARTICIPANTS

A consecutive cohort of 111 patients undergoing PP (study n = 47) compared to historical controls (n = 64).

INTERVENTIONS

All patients received intraoperative acetaminophen, dexmedetomidine, and opioids while the study group received an additional single dose of ketorolac (0.5 mg/kg) at the conclusion of PP.

MAIN OUTCOME MEASURES

Safety of ketorolac was measured by significant bleeding complications and need for supplementary oxygen. Efficacy was assessed through bleeding, Face Legs Activity Cry Consolability (FLACC) scale, and opioid dose.

RESULTS

Length of stay was similar for both groups (control group 38.5 hours [95% CI: 3.6-43.3] versus study group 37.6 hours [95% CI: 31.3-44.0], P = .84). There were no significant differences in all postoperative FLACC scales. The mean dose of opioid rescue medication measured as morphine milligram equivalents did not differ between groups (P = .56). Significant postoperative hemorrhage was not observed.

CONCLUSIONS

This is the first prospective study to evaluate the safety and efficacy of single-dose ketorolac after PP. Although lack of standardization between study and historical control groups may have precluded observation of an analgesic benefit, analysis demonstrated a single dose of ketorolac after PP is safe. Further investigations with more patients and different postoperative regimens may clarify the role of ketorolac in improving pain after PP.

For Patients With Isolated Cleft Palate Does Revision Palatoplasty Have an Increased Risk of Inpatient Complication Compared to Primary Palatal Repair?

OBJECTIVE

The purpose of this study was to determine whether revision palatoplasty was associated with increased rates of inpatient complication and wound dehiscence compared to primary palatal repair.

MATERIALS AND METHODS

This was a retrospective study of patients with isolated cleft palate treated with primary palatoplasty or revision surgery for fistula repair. The records were obtained from the Kids' Inpatient Database between 2000 and 2014. The primary predictor was the type of surgery, classified as either primary or revision palatoplasty. Secondary predictors included demographics and comorbidities. Primary study outcomes were the postoperative complication and dehiscence rates as noted during the hospitalization course. The secondary outcomes related to health care utilization as measured through length of stay (LOS) and hospital charges.

RESULTS

A total of 5357 total admissions (95.5% primary, 4.5% revision) were included in the final sample. Fistula repairs (odds ratio = 14.37, P < .01) had significantly greater odds of wound dehiscence. The rates of inpatient complication ranged from 3.5% to 3.7%, and there were no significant differences between primary and revision surgery (P = .82). Complications were independently associated with insurance status and congenital anomalies. Complications and wound dehiscence both significantly increased the LOS and the hospital charges. Fistula repairs had a shorter mean LOS (P = .02), however this did not translate into cost savings (P = .60).

CONCLUSIONS

Although the rates of inpatient complications were not significantly different, revision palatoplasty was associated with a greater odds of wound dehiscence. Failure of a primary repair may portend an increased risk of wound failure with subsequent surgeries.

Aboard the Smile Train: Outcomes of Primary Cleft Palate Repair at a Tertiary Care Center: À bord du Smile Train : les résultats cliniques de réparations de fentes palatines dans un centre de soins tertiaires

Introduction

Cleft palate repair is considered to be a safe procedure, yet still carries a 5% to 30% risk of complications. This study sought to assess the outcomes of this procedure in a high-burden Asian country that partners with the Smile Train to perform cleft surgeries.

Methods

The Aga Khan University medical records database was queried for pediatric patients undergoing cleft surgery between 2014 and 2017. Data were abstracted from the patient medical records, and details of the clinical, demographic factors, and postoperative outcomes were assessed.

Results

Among 142 patients with orofacial clefts, 102 (72%) underwent primary cleft palate repair, one-third (n = 36, 35%) of whom were operated as part of the Smile Train. The median preoperative hemoglobin was 11.4 g/dL (interquartile range: 10.7-12.0 g/dL), whereas the median weight was 8.3 kg (7.7-11.4 kg). Nearly two-thirds (n = 64, 63%) of the cohort underwent preoperative cardiology screening, with only a minority undergoing orthodontic treatment (n = 6, 6%). Approximately 15% (n = 15) of patients experienced a postoperative complication, most often a fistula (n = 11, 73%). On multivariable analysis, with each unit increase in hemoglobin levels, there was a 50% reduction in the odds of experiencing a complication (odds ratio: 0.51, 95% CI: 0.28-0.87). There were no in-patient deaths among the cohort.

Conclusion

The results of the current study provide useful information to key stakeholders including patients, plastic surgeons, and policy makers on the outcomes of cleft palate repair in a developing country.

Should Cleft Surgery Always be Performed During the Matutine Time? Analysis of Early and Late Postoperative Complications in a Cleft Center

OBJECTIVE

Surgeries performed in the afternoon schedule were discouraged by Smile Train Foundation for patients younger than 2 years. The aim of this study is to present the incidence of complications discriminating time of surgery (morning/afternoon) in a reference center in Curitiba (Brazil) during 2017.

DESIGN

Retrospective study that evaluated all cleft surgeries that were performed at Assistance Center for Cleft Lip and Palate during 2017. Complications correlated with surgery period (morning/afternoon), type of surgery, and operating surgeon were studied. Statistical analysis was performed to find any association between discrete variables.

SETTING

Tertiary, institutional.

PARTICIPANTS

One hundred eighty-seven patients with cleft lip and/or cleft palate/cleft lip and palate, who were evaluated and submitted to surgery in the center and had less than 24 months of age, were included in the study.

INTERVENTIONS

One hundred twenty-four cheiloplasties and 63 palatoplasties were performed.

MAIN OUTCOME MEASURE

Incidence of complications.

RESULTS

From the total of cheiloplasties, the number of complications was 2 (1.6%) and from the total of palatoplasties the number of complications was 11 (17%); 8.1% of surgeries that were performed in the morning had any complication compared to 5.1% of surgeries performed in the afternoon. Statistical analysis of discrete variables with χ² test showed no correlation between surgery schedule and complications (χ² = 0.62).

CONCLUSION

The number of complications was not higher in the afternoon scheduled surgeries. Surgeon expertise had a statistically significant correlation with the absence of complications (χ² = 20.57).

The Impact of Surgical Volume on Outcomes and Cost in Cleft Repair: A Kids' Inpatient Database Analysis

BACKGROUND

Centralization of specialist services, including cleft service delivery, is occurring worldwide with the aim of improving the outcomes. This study examines the relationship between hospital surgical volume in cleft palate repair and outcomes.

METHODS

A retrospective analysis of the Kids' Inpatient Database was undertaken. Children 3 years or younger undergoing cleft palate repair in 2012 were identified. Hospital volume was categorized by cases per year as low volume (LV; 0-14), intermediate volume (IV; 15-46), or high volume (HV; 47-99); differences in complications, hospital costs, and length of stay (LOS) were determined by hospital volume.

RESULTS

Data for 2389 children were retrieved: 24.9% (n = 595) were LV, 50.1% (n = 1196) were IV, and 25.0% (n = 596) were HV. High-volume centers were more frequently located in the West (71.9%) compared with LV (19.9%) or IV (24.5%) centers (P < 0.001 for hospital region). Median household income was more commonly highest quartile in HV centers compared with IV or LV centers (32.3% vs 21.7% vs 18.1%, P < 0.001). There was no difference in complications between different volume centers (P = 0.74). Compared with HV centers, there was a significant decrease in mean costs for LV centers ($9682 vs $,378, P < 0.001) but no significant difference in cost for IV centers ($9260 vs $9682, P = 0.103). Both IV and LV centers had a significantly greater LOS when compared with HV centers (1.97 vs 2.10 vs 1.74, P < 0.001).

CONCLUSIONS

Despite improvement in LOS in HV centers, we did not find a reduction in cost in HV centers. Further research is needed with analysis of outpatient, long-term outcomes to ensure widespread cost-efficiency.

Psychological Well-being and Medical Guidance of Parents of Children With Cleft in Belgium During Feeding Problems of the Child: A Mixed Method Study

PURPOSE

Cleft is one of the most common anomalies affecting 1 in every 500-750 newborns. Depending on the type of cleft and its size, these children may experience feeding problems immediately after birth. Cleft has consequences for the child, as well as for the parents. The aim of this study was to gain a better understanding on the factors influencing the psychological well-being of the parents. Also, the experiences of parents of children with feeding problems and the received medical guidance were studied.

DESIGN AND METHODS

A mixed method convergent parallel design was used. In the quantitative study, a cross-sectional design was applied, in which parents completed 3 validated questionnaires about their psychological well-being. For the qualitative research a phenomenological design was used to conduct semi-structured interviews. Ninety parents agreed to join the quantitative study, of which 15 participated in the qualitative study as well.

RESULTS

The timing of the diagnosis revealed a significant difference in the depression and stress scores, while the number of children was significant for depression, anxiety, and stress. Other parental- and child-related factors did not cause a significant difference in psychological well-being. Different opinions about medical guidance and feeding problems came up during the interviews.

CONCLUSION

With these results, a recommendation toward future medical guidance can be given. The number of children and the timing of diagnosis were found to be significant variables determining the psychological well-being of the parents. All parents agreed on the need for a point of contact and an umbrella framework for a clearer guidance. Moreover, caregivers should have more knowledge about cleft and associated feeding problems.

The Incidence of Sleep Disordered Breathing One Week After Primary Palatoplasty: Evaluation With Overnight Pulse Oximetry

BACKGROUND

Sleep disordered breathing (SDB) is defined as a series of disorders including snoring, obstructive sleep apnea, and hypopnea. Few studies investigated the incidence of SDB following primary palatoplasty with objective testing. The aims of this study were to elucidate the prevalence and degree of SDB approximately 1 week following primary palatoplasty with objective testing and to clarify the risk factors.

METHOD

A retrospective review was performed on children who underwent primary palatoplasty between April 2013 and July 2017 at National Center for Child Health and Development, Tokyo, Japan. As a national center, the authors accept many syndromic patients. The authors keep all patients after palatoplasty intubated and observe them overnight in intensive care unit to reduce the risks of respiratory events. Patients were evaluated with overnight pulse oximetry on 5 to 7 days postoperatively.

RESULTS

Forty-four patients were included, and 30% of the patients were associated with congenital anomaly. Thirteen patients (30%) were diagnosed with SDB. None of the patients required additional treatment after the evaluation. Laryngomalacia and postoperative oxygen requirement significantly correlated with postoperative SDB.

CONCLUSION

Approximately one-third of the patients may be at the risk of SDB 1 week after primary palatoplasty. Patients with history of laryngomalacia or those who required oxygen support for prolonged time after primary palatoplasty should be cared for significantly high risk of postoperative SDB.

In utero exposure to arsenic in tap water and congenital anomalies: A French semi-ecological study

INTRODUCTION

Congenital anomalies (CA) are responsible for high rates of mortality and long-term disabilities. Research on their risk factors including environmental factors is needed. Studies on exposure to arsenic (As) in tap water and the risk of CA have not provided conclusive evidence, particularly when levels of exposure were low (from 10 to 50 μg As/L). The main objective of this study was to assess the association between exposure to As in tap water and the risk of any major CA. The secondary objectives were to assess this association for the most common types of congenital anomalies (in the heart, musculoskeletal, urinary and nervous systems).

METHODS

A semi-ecological study was conducted from births recorded at the University Hospital of Clermont-Ferrand, France, in 2003, 2006 and 2010. The medico-obstetric data were available at individual level. Children with congenital anomalies were identified from the database of the regional registry of congenital anomalies: the Centre d'Etudes des Malformations Congénitales Auvergne (CEMC-Auvergne). As exposure was estimated from the concentrations of As measured during sanitary control of tap water supplied in the mothers' commune of residence (aggregate data). French guidelines for As in tap water were used to identify the two groups: "≥ 10 μg As/L group" and "[0-10) μg As/L group". Multivariable logistic regression models were fit.

RESULTS

5263 children (5.1% with a CA) were included. In stratified analysis by gender of the child, positive associations between As exposure exceeding 10 μg/L and risk of any major CA (adjusted OR = 2.41; 95%CI: 1.36-4.14) and of congenital heart anomalies (adjusted OR = 3.66; 95%CI: 1.62-7.64) were only shown for girls. No association was found for boys.

CONCLUSION

This French semi-ecological study provides additional arguments for the association between exposure to As exceeding 10 μg/L in tap water and the risk of CA especially in a context of low exposure. Further studies are needed to better understand the interaction between arsenic exposure and child gender.

Predicting Adverse Perioperative Events in Patients Undergoing Primary Cleft Palate Repair

Objective:

This study aimed to identify risk factors for adverse perioperative events (APEs) after cleft palatoplasty to develop an individualized risk assessment tool.

Design:

Retrospective cohort.

Setting:

Tertiary institutional.

Patients:

Patients younger than 2 years with cleft palate. Interventions: Primary Furlow palatoplasty between 2008 and 2011.

Main Outcome Measure(s):

Adverse perioperative event, defined as laryngo- or bronchospasm, accidental extubation, reintubation, obstruction, hypoxia, or unplanned intensive care unit admission.

Results:

Three hundred patients averaging 12.3 months old were included. Cleft distribution included submucous, 1%; Veau 1, 17.3%; Veau 2, 38.3%; Veau 3, 30.3%; and Veau 4, 13.0%. Pierre Robin (n = 43) was the most prevalent syndrome/anomaly. Eighty-three percent of patients received reversal of neuromuscular blockade, and total morphine equivalent narcotic dose averaged 0.19 mg/kg. Sixty-nine patients (23.0%) had an APE, most commonly hypoventilation (10%) and airway obstruction (8%). Other APEs included reintubation (4.7%) and laryngobronchospasm (3.3%). APE was associated with multiple intubation attempts (odds ratio [OR] = 6.6, P = .001), structural or functional airway anomaly (OR = 4.5, P < .001), operation >160 minutes (OR = 2.2, P = .04), narcotic dose >0.3 mg/kg (OR = 2.3, P = .03), inexperienced provider (OR = 2.1, P = .02), and no paralytic reversal administration (OR = 2.0, P = .049); weight between 9 and 13 kg was protective (OR = 0.5, P = .04). Patients were risk-stratified according to individual profiles as low, average, high, or extreme risk (APE 2.5%-91.7%) with excellent risk discrimination (C-statistic = 0.79).

Conclusions:

APE incidence was 23.0% after palatoplasty, with a 37-fold higher incidence in extreme-risk patients. Individualized risk assessment tools may enhance perioperative clinical decision making to mitigate complications.
