Abstract
Objective: This review was conducted to define the natural history of unoperated Beckwith-Wiedemann syndrome (BWS) macroglossia and the effect of tongue reduction surgery upon breathing, eating, speaking and dentoskeletal development in individuals having BWS. Design: This is a retrospective study of medical records. SETTING All patients were evaluated and treated in one of two Children's Hospitals by an ACPA approved Craniofacial Team. PATIENTS/PARTICIPANTS Medical records were reviewed of 526 individuals having a diagnosis of BWS and evaluated in-person by a single craniofacial surgeon between 1986 and 2014 in conjunction with a series of multi-disciplinary craniofacial team colleagues. 28 individuals were excluded having had multiple tongue reductions elsewhere. 498 individuals comprise the "pre tongue-reduction group". The "post tongue-reduction group" consists of 391 individuals who underwent surgical tongue reduction by one surgeon using one technique between 1986 and 2014. MAIN OUTCOME MEASURES The primary outcome measure was change in anterior dental occlusion following tongue reduction surgery. Tongue reduction surgery was performed on the assumption that it would improve dentoskeletal relationships. Secondary outcome measures were: breathing, feeding/swallowing, and speech. Results: A significant difference (p<0.001) over time between the two groups was found with less anterior occlusal abnormality in the tongue reduction group. Tongue reduction surgery had no mortality and minimal morbidity for breathing, feeding/swallowing, and speech and can ameliorate obstructive sleep apnea. Conclusions: Surgical tongue reduction for BWS macroglossia is recommended for the infant or child in primary dentition with a grossly abnormal anterior tooth/jaw relationship and/or obstructive sleep apnea.

Associations between the timing of tongue reduction surgery, (Epi)genotype, and dentoskeletal development in patients with Beckwith-Wiedemann syndrome. J Craniomaxillofac Surg 2023; 51:568-573. [PMID: 37599200 DOI: 10.1016/j.jcms.2023.07.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2023] [Accepted: 07/30/2023] [Indexed: 08/22/2023] Open
Abstract
Tongue reduction surgery is often pursued to manage the adverse effects of macroglossia in patients with Beckwith-Wiedemann syndrome (BWS). This study characterized dental outcomes in patients with BWS based on surgical timing and molecular diagnosis. A retrospective study was designed to include patients with BWS over the age of two who had clinical or radiographic documentation of dental development. Patients were grouped by history of tongue reduction surgery and surgical timing (early: <12 months). One hundred three patients were included (55 no tongue reduction, 18 early, 30 late). Patients who underwent late surgery had lower odds of class I occlusion (OR 0.11, 95% CI 0.02-0.58, p = 0.009) and higher odds of anterior open bite (OR 7.5, 95% CI 1.14-49.4, p = 0.036). Patients with clinical diagnoses and negative molecular testing had anterior open bite less frequently than patients with imprinting center 2 loss of methylation and paternal uniparental isodisomy of 11p15.5 (p = 0.009). Compared to reference values, patients who had tongue reductions had an increased mandibular plane angle (32.0 ± 4.5° versus 36.9 ± 5.0°, p = 0.001), indicative of hyperdivergent growth. The results of this study help to understand the complex nature of dentoskeletal growth in BWS and shed insight on how surgical timing and molecular diagnosis influence prognosis.

Dentoskeletal features and growth pattern in Beckwith-Wiedemann spectrum: is surgical tongue reduction always necessary? Clin Oral Investig 2023; 27:4271-4277. [PMID: 37162568 PMCID: PMC10415414 DOI: 10.1007/s00784-023-05043-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2022] [Accepted: 04/25/2023] [Indexed: 05/11/2023]
Abstract
OBJECTIVES The role of tongue reduction surgery (TRS) in preventing excessive mandibular growth and anterior open bite in children with Beckwith-Wiedemann Spectrum (BWSp) is still controversial. This cross-sectional study aimed at comparing craniofacial growth pattern in children affected by BWSp either treated or not treated with early TRS for severe macroglossia. Considering the invasive nature of such surgery, the present study could help in clarifying the need for TRS to reduce or prevent growth disturbances. MATERIALS AND METHODS Orthopantomography and lateral skull x-ray images were taken either from surgically treated or non-surgically treated patients, aged 5 to 8 years, to compare dentoskeletal features and craniofacial growth by cephalometric analysis. Molecular testing results were collected from their medical records. RESULTS Eighteen BWSp patients were consecutively recruited: 8 underwent TRS at 14.9 ± 2.2 months of age, while 10 did not. Anterior open bite and dental class III were more frequently observed in the surgically treated group, but none showed skeletal class III. No statistically significant differences were observed in growth pattern, but children treated with TRS showed a tendency towards both maxillary and mandibular prognathism with protruding lower lip. Growth pattern seemed to be not related to molecular subtypes. CONCLUSIONS These preliminary data suggest that early TSR does not improve craniofacial growth pattern and dentoskeletal features in BWSp children. CLINICAL RELEVANCE Reductive glossectomy may not be justified for preventing or avoiding oro-facial deformities in BWSp; therefore, early monitoring of maxillofacial development of each affected child has a great clinical significance.

Abstract
About 90% of children diagnosed with classic BWS have macroglossia, and 40% of them are submitted to surgical tongue reduction. The purpose of our article is to present a case study of a 5-month-old child with BWS who was treated with an original therapy for stimulation of oral areas innervated by the trigeminal nerve. The therapy included stimulation of the upper and lower lip and muscles of the floor of the mouth. The treatment was provided by a therapist once a week. In addition, the child was stimulated every day at home by his mother. After 3 months, a significant improvement in oral alignment and function was achieved. Preliminary observations of therapy application for stimulation regions innervated by the trigeminal nerve in children with Beckwith-Wiedemann syndrome seem promising. The original therapy for stimulation of oral areas innervated by the trigeminal nerve is a good alternative to existing methods of surgical tongue reduction in children with BWS and macroglossia.

Abstract
OBJECTIVE As the most common feature of Beckwith-Wiedemann syndrome (BWS), macroglossia may influence the quality of life, maxillofacial growth, and speech development of children. The retrospective study aimed to investigate the therapeutic effect of partial glossectomy combined with radiofrequency ablation (RFA) for macroglossia patients in BWS. METHODS A retrospective study was conducted in BWS-derived macroglossia patients who underwent partial glossectomy combined with RFA from May 2019 to January 2021. In total, 35 patients consisting of 17 males and 18 females met the inclusion criteria and underwent surgery by the same plastic surgeon. Demographic characteristics, BWS features, operation details, preoperative and postoperative outcomes, satisfaction evaluations, and subgroup analysis were collected and assessed. RESULTS Of the 35 patients involved, the average age at the time of surgery was 14.05±8.08 months, and the average surgery duration was 48.17±6.72 minutes. Only 1 patient suffered ventral tongue wound dehiscence, and the rest of the patients did not develop any other complications. The severity and frequency of tongue protrusion, drooling, snoring, and feeding difficulty were significantly ameliorated. The patient's parents showed satisfaction towards the overall surgery, tongue's appearance, and tongue's motor function. Tongue's height decreased from 32.09±1.16 mm before the operation to 29.29±1.33 mm after the operation. CONCLUSION The partial glossectomy combined RFA exerts a safe, effective and viable technique to treat BWS-derived macroglossia.

Abstract
Beckwith-Wiedemann syndrome (BWS) is a genetic disease with phenotypic variability and the following signs: macroglossia, asymmetry, lateralised overgrowth, overgrowth of the internal organs, abdominal wall defects, neonatal hypoglycemia and increased risk of embryonic tumours. The prevalence is reported as being between 1 in 10,000 and 1 in 21,000 live births. The disease is caused by molecular changes in gene clusters on the short arm of chromosome 11 region P15.5. We present the case of a female, born preterm at 32 0/7 weeks. A UPD(11)pat-mutation was diagnosed postnatally. The particular feature of her case was an early tongue reduction surgery which was necessary because of drinking and breathing difficulties. Long-lasting hypoglycemia was difficult to treat.

Abstract
Due to associated maxillofacial growth anomalies and the impairment of oral functions, macroglossia may negatively impact the oral health-related quality of life (OHRQoL) of people with Beckwith–Wiedemann syndrome (BWS). Therefore, the aim of this cross-sectional study was to determine the OHRQoL of Italian children and adolescents with BWS compared to healthy peers and to identify which symptoms related to macroglossia had the highest impact. A total of 48 patients with BWS and 48 age- and gender-matched controls completed the Italian version of OHIP-14 and a questionnaire on functional, oral and aesthetic outcomes. Parents of patients with BWS who had undergone tongue reduction surgery (TRS) answered additional questions related to surgery. The BWS group scored higher than controls on the total OHIP-14 and on the dimensions of oral function (p: 0.036) and psychosocial impact (p: 0.002), indicating a reduced OHRQoL. Neither gender nor age had an impact on OHRQoL. Scores were worse in children and adolescents treated with TRS, as most of them still had open bite malocclusion and speech difficulties. The OHRQoL of children and adolescents affected by BWS is worse than that of their healthy peers in spite of the surgical treatment of macroglossia.

Abstract
INTRODUCTION Macroglossia occurs in 80% to 99% of patients with Beckwith-Wiedemann syndrome (BWS) and a variety of surgical techniques for tongue reduction are offered by surgeons. The purpose of this study is to evaluate the postoperative outcomes of the anterior "W" tongue reduction technique in patients with BWS. METHODS A retrospective review was conducted of all patients diagnosed with BWS that underwent an anterior "W" tongue reduction for macroglossia in the past 7 years, performed by 2 surgeons. Demographics, procedural characteristics, perioperative outcomes, and complications were assessed. RESULTS A total of 19 patients met inclusion criteria consisting of 8 male and 11 female patients. The mean age at the time of surgery was 405 days, mean surgeon operating time was 1.06 h, and mean length of follow-up was 467 days. Postoperative oral competence was observed in 100% of patients. There was no reported history of sleep apnea or airway compromise. Speech delay was seen in 4 patients pre- and postoperatively. Feeding issues decreased from 7 patients preoperatively to 1 patient postoperatively. Preoperative prevalence of class III malocclusion (53%) and isolated anterior open bite (26%) decreased postoperatively to 37% and 16%, respectively. The only reported complications were superficial tip wound dehiscence in 3 patients treated with nystatin antifungal therapy. None of the patients required revisional surgery. CONCLUSION Patients treated with the anterior "W" tongue reduction technique had low rates of perioperative complications and significant improvements in oral competence. Anterior "W" tongue reduction is safe and effective for the correction of macroglossia in patients with BWS.

Abstract
AIM To report the pre- and post-frenectomy findings of a patient with Beckwith-Wiedemann syndrome. METHODS AND RESULTS Clinical case report of a patient with a confirmed genetic-molecular diagnosis of the referred syndrome. The minor was evaluated and reassessed by the protocol for the evaluation of the tongue's frenulum for babies in two moments: pre-surgical and 2 months after the frenectomy. The surgical procedure was performed using the traditional technique and, after the procedure, the minor was breastfed and received photobiomodulation with a red laser. The minor obtained 16 points in the neonatal tongue screening test, indicating the need for a frenectomy. Thus, she was referred to a dentist for surgery. After the surgical procedure, macroglossia was observed as a maternal complaint (previously not mentioned). The wound healing was satisfactory, and the total score obtained in the reapplication of the protocol (five points) showed functional results of improvements in sucking and tongue mobility, justifying the importance of the frenectomy. CONCLUSION Frenectomy, despite showing macroglossia related to the Beckwith-Wiedemann syndrome, allowed anatomical and functional advances of the tongue in the present clinical case.

Investigation of (epi)genotype causes and follow-up manifestations in the patients with classical and atypical phenotype of Beckwith-Wiedemann spectrum. Am J Med Genet A 2021; 185:1721-1731. [PMID: 33704912 DOI: 10.1002/ajmg.a.62158] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 01/24/2021] [Accepted: 02/13/2021] [Indexed: 11/05/2022]
Abstract
Beckwith-Wiedemann syndrome (BWS) is a genomic imprinting disorder, characterized by macroglossia, abdominal wall defects, lateralized overgrowth, and predisposition to embryonal tumors. It is caused by the defect of imprinted genes on chromosome 11p15.5, regulated by imprinting control (IC) domains, IC1, and IC2. Rarely, CDKN1C and chromosomal changes can be detected. The aim of this study is to retrospectively evaluate 55 patients with BWS using the new diagnostic criteria developed by the BWS consensus, and to investigate (epi)genetic changes and follow-up findings in classic and atypical phenotypes. Loss of methylation in IC2 region (IC2-LoM), 11p15.5 paternal uniparental disomy (pUPD11), and methylation gain in IC1 region (IC1-GoM) are detected in 31, eight, and five patients, respectively. Eleven patients have had no molecular defects. Thirty-five patients are classified as classical and 20 as atypical phenotype. Patients with classical phenotype are more frequent in the IC2-LoM (25/31), while patients with atypical phenotype are common in the pUPD11 group (5/8). Malignant tumors have developed in six patients (10.9%); three of these patients have IC1-GoM, two pUPD11, one IC2-LoM genotype, and four an atypical phenotype. We observed that the face was round in the infantile period and elongated as the child grew-up, developing prognathism and becoming asymmetrical if hemi-macroglossia was present in the classical phenotype. These findings were mild in the atypical phenotype. These results support the importance of using the new diagnostic criteria to facilitate the diagnosis of patients with atypical phenotype who have higher tumors risk. This study also provides important information about facial gestalt.

Abstract
OBJECTIVE Macroglossia is a characteristic feature of Beckwith-Wiedemann syndrome (BWS), commonly treated with reduction glossectomy to restore form and function. There exists no consensus on the perioperative management of these patients undergoing tongue reduction surgery, including anecdotal information regarding how long postoperative intubation should be maintained. The aim of this study is to evaluate the necessity of prolonged postoperative intubation in patients receiving tongue reduction surgery via the surgical and anesthetic management methods at our center. DESIGN Retrospective case series. SETTING Institutional care at Level I Children's Hospital. PARTICIPANTS All children less than 18 years old with BWS and congenital macroglossia who underwent tongue reduction surgery over 5 consecutive years at our center (N = 24). INTERVENTIONS Tongue reduction surgery via the "W" technique. MAIN OUTCOME MEASURES Success of immediate postoperative extubation and related surgical complications. RESULTS Immediate, uncomplicated postoperative extubation was successfully performed in all patients who received tongue reduction surgery for congenital macroglossia. CONCLUSIONS Prolonged postoperative intubation for tongue reduction surgery may not be necessary as immediate, uncomplicated postoperative extubation was achieved in 100% of patients who received tongue reduction surgery at our center.

Abstract
AIM This study compares long-term mandibular growth between a group of Beckwith-Wiedemann Syndrome (BWS) patients who underwent glossectomy at an early age and a group of patients not operated. METHODS Cephalometric measurements were performed in BWS patients comparing the data obtained between a group of patients operated at an early age and a group of non-operated patients who declined surgery. Statistics included independent sample T-test. RESULTS Twenty-four out of 78 BWS patients followed since birth completed longitudinal cephalometric x-rays at age 5, 10 and 15. Eighteen patients needed early surgery. Eleven families accepted glossectomy at 2.3 ± 1.3 years of age; seven declined surgery. No differences in mandibular growth were found between the two groups. Inclination of maxillary incisors results were statistically greater in the non-operated group (operated compared to the non-operated group: 103.58 ± 11.30 Vs 108.98 ± 12.47; p-value 0.0168 at 5; 107.06 ± 7.98 Vs 115.14 ± 7.05; p-value 0.0206 at 10; 109.80 ± 4.68 Vs 116.75 ± 5.28; p-value 0.0233 at 15). CONCLUSION Macroglossia has no role in the post-natal mandibular overgrowth in BWS and mandibular overgrowth is part of the syndrome. Therefore, early glossectomy does not change mandibular growth and does not prevent the development of class III skeletal malocclusion in these patients.

Abstract
BACKGROUND Macroglossia, a cardinal feature of the (epi)genetic disorder Beckwith-Wiedemann syndrome, is associated with obstructive sleep apnea, speech and/or feeding difficulties, and dental or jaw malalignment. These sequelae may be treated and/or prevented with tongue reduction surgery; the authors sought to determine whether certain Beckwith-Wiedemann syndrome patients may benefit from early surgical intervention before age 12 months. METHODS The authors conducted a retrospective review of patients with Beckwith-Wiedemann syndrome who underwent tongue reduction from 2014 to 2019. The authors assessed primary outcomes of change in obstructive sleep apnea by polysomnography, respiratory support required, and feeding route before and after tongue reduction, and reviewed postoperative complications and the need for repeated tongue reduction. RESULTS Of the 36 patients included, the median age at tongue reduction was 9.5 months (interquartile range, 3.8 to 22.8 months). For those with severe obstructive sleep apnea, there was a significant reduction in the obstructive apnea hypopnea index from 30.9 ± 21.8 per hour to 10.0 ± 18.3 per hour (p =0.019) and improvement in nadir oxyhemoglobin saturation from 72 ± 10 percent to 83 ± 6 percent (p =0.008). Although there was no significant change in overall supplemental feeding tube or respiratory support, there were specific patients who experienced clinically meaningful improvement. Of note, these positive outcomes applied equally to those who underwent surgery at a younger age (<12 months). To date, only one patient required a repeated tongue reduction. CONCLUSION Based on improved polysomnographic findings and rarity of surgical complications or repeated surgery, the authors' data support the safety and efficacy of this early intervention when clinical indications are present and an experienced multidisciplinary team is available for consultation. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
Abnormally excessive growth results from perturbation of a complex interplay of genetic, epigenetic, and hormonal factors that orchestrate human growth. Overgrowth syndromes generally present with inherent health concerns and, in some instances, an increased risk of tumor predisposition that necessitate prompt diagnosis and appropriate referral. In this review, we introduce some of the more common overgrowth syndromes, along with their molecular mechanisms, diagnostics, and medical complications for improved recognition and management of patients affected with these disorders.

Abstract
INTRODUCTION Current protocols for venous thromboembolism (VTE) prophylaxis after craniofacial surgery (CFS) vary widely with substantial disagreements in both indications and managements. An evidence-based approach to this issue requires the following: the incidence of postoperative VTE, comorbidities associated with coagulopathy, risk reduction after VTE prophylaxis, and complications attributable to prophylaxis. This study addresses the first two. DESIGN Retrospective cross-sectional study. METHODS Discharge data from 64,170 patients undergoing CFS between 2008 and 2013 extracted from the Healthcare Cost and Utilization Project Nationwide Inpatient Sample were analyzed. The outcome measures extracted were: deep venous thrombosis, pulmonary embolism, demographic data, common comorbidities, length of stay, total cost, and discharge outcome. RESULTS Diagnoses of deep venous thrombosis or pulmonary embolism, collectively classified as VTE, were observed in 355 (0.55%) of 64,170 patients discharged after CFS. Other surgeries exhibited a VTE rate of 1.17%. Men exhibited nearly double the incidence of VTE relative to women (0.69% compared with 0.37% respectively, P < 0.001), and the risk factors of adulthood, advanced age, cardiovascular disease, obesity, and malignancy were associated with increased VTE incidence with odds ratios of 9.93, 3.66, 1.80, 2.02, and 2.02, respectively (P < 0.005). Tobacco use did not exhibit any significant association (odds ratio, 0.94; P = 0.679). Afflicted patients experienced 4.60 times longer hospital stays averaging 23.8 days (95% confidence interval, 21.4-26.2; P < 0.001) compared the average of 5.2 days experienced by CFS patients without VTE. They incurred an average cost of US $298,228 (95% confidence interval, 262,726 to 333,731; P < 0.001) which was 4.17 times the US $72,376 expense of treating other CFS patients. The likelihood for a CFS patient to experience a poor outcome at the time of discharge was 54.6% higher after VTE. CONCLUSIONS The risk of postoperative VTE after CFS is significantly increased in adults, patients with advanced age, cardiovascular disease, obesity, and malignancy. However even in those high-risk cases, postoperative VTE incidence remains relatively low after CFS. These findings in conjunction with further study regarding the risk associated with the addition of VTE chemoprophylaxis compared against mechanical VTE prophylaxis, such as sequential pneumatic compression stockings, may determine whether routine use of VTE chemoprophylaxis is appropriate.

Abstract
Macroglossia is observed in the majority of patients with Beckwith-Wiedemann syndrome (BWS), a congenital condition with characteristic anomalies. In addition, sleep disordered breathing (SDB) associated with macroglossia has occasionally been noted in BWS patients, for which tongue reduction surgery is generally performed. However, macroglossia is related to various health problems, such as eating and articulation disorders, attention deficit disorder, enuresis, and thorax deformation, as well as aesthetic issues. Therefore, in addition to treating airway obstruction, tongue reduction surgery can also exert favorable effects on the overall quality of life (QOL) of patients. However, surgical indications for tongue reduction have yet to be established and reports on QOL assessments after surgery are rare. The OSA-18 questionnaire is used for screening SDB and is also useful for assessing the effect of tongue reduction surgery on QOL. We report a patient whose QOL was improved by tongue reduction surgery. On the basis of our patient's results, we recommend tongue reduction surgery in early childhood not only to treat SDB but also to improve QOL.

Abstract
Beckwith-Wiedemann syndrome (BWS) is a human genomic imprinting disorder that presents with a wide spectrum of clinical features including overgrowth, abdominal wall defects, macroglossia, neonatal hypoglycemia, and predisposition to embryonal tumors. It is associated with genetic and epigenetic changes on the chromosome 11p15 region, which includes two imprinting control regions. Here we review strategies for diagnosing and managing BWS and delineate commonly used genetic tests to establish a molecular diagnosis of BWS. Recommended first-line testing assesses DNA methylation and copy number variation of the BWS region. Tissue mosaicism can occur in patients with BWS, posing a challenge for genetic testing, and a negative test result does not exclude a diagnosis of BWS. Further testing should analyze additional tissue samples or employ techniques with higher diagnostic yield. Identifying the BWS molecular subtype is valuable for coordinating patient care because of the (epi)genotype-phenotype correlations, including different risks and types of embryonal tumors.

Abstract
Objective: To profile the pre- and post-operative feeding difficulties in infants with macroglossia in Beckwith Wiedemann Syndrome (m-BWS) who have had tongue reduction surgery (TRS) and to pilot a bespoke feeding rating scale. Design: Retrospective consecutive case series designed with two pre-operative and one 3-month post-operative feeding assessments. A 4-point Likert-type scale was developed and applied retrospectively to describe the feeding behaviors for liquids, purées, and solids. Descriptive and non-parametric statistics were used. Setting: National service for children with m-BWS at a pediatric hospital. Patients: Twenty-five infants, age range 4 to 12 months at initial assessment, underwent TRS (median age = 16 months). Intervention: Tongue reduction surgery. Outcome Measure: Oral and selected pharyngeal stage feeding behaviors on liquids, purées, and solids. Results: Pre-operative profile: Most feeding difficulties arose at the oral stage due to the macroglossia impacting important lingual movements. Difficulties were found with lip seal formation, biting, bolus manipulation and tongue lateralization. Aspiration risk was found in >75%. Texture modification was indicated for purées and solids. Post-operative profile: There were statistically significant differences for each consistency pre- and post-operatively. Eighty-four percent of infants had age-appropriate drinking and eating skills. Mild residual difficulties with biting, tongue lateralization, and bolus manipulation remained for solids in four infants. Conclusions: Feeding difficulties are common pre-operatively in m-BWS, putting infants at risk of aspiration if left unmanaged. TRS was effective in reducing or eliminating them. This is the first systematic report of infant feeding in m-BWS pre- and post-TRS.

Tongue reduction in Beckwith-Wiedemann syndrome: outcome and treatment algorithm. Int J Oral Maxillofac Surg 2018; 48:9-16. [PMID: 30057238 DOI: 10.1016/j.ijom.2018.07.008] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2018] [Revised: 05/30/2018] [Accepted: 07/11/2018] [Indexed: 11/27/2022]
Abstract
Beckwith-Wiedemann syndrome is a rare congenital overgrowth disorder with macroglossia being one of the cardinal symptoms. In pronounced cases, macroglossia can lead to airway obstruction, musculoskeletal alterations and functional deficits. Surgical tongue reduction is performed at varying ages and with different techniques. This study evaluated perioperative complications, as well as long-term aesthetic and functional outcomes, in a large cohort. A total of 68 patients, treated either surgically or conservatively, were included. Depending on the severity of macroglossia, patients were divided into three groups to determine the treatment algorithm. Complications after surgical tongue reduction were prolonged intubation and revision due to dehiscence or haematoma. In the long term, no patient suffered from impaired sense of taste or paresthesia, although the shape of the tongue was disproportional in 85%. With the present treatment algorithm, operative tongue reduction exerts a positive influence on skeletal, dentoalveolar and functional development with sufficient long-term outcome and high grade of satisfaction of the patients. Supportive therapy in an interdisciplinary centre is of fundamental importance for both surgical and conservative treatment.

Abstract
Beckwith-Wiedemann syndrome (BWS), a human genomic imprinting disorder, is characterized by phenotypic variability that might include overgrowth, macroglossia, abdominal wall defects, neonatal hypoglycaemia, lateralized overgrowth and predisposition to embryonal tumours. Delineation of the molecular defects within the imprinted 11p15.5 region can predict familial recurrence risks and the risk (and type) of embryonal tumour. Despite recent advances in knowledge, there is marked heterogeneity in clinical diagnostic criteria and care. As detailed in this Consensus Statement, an international consensus group agreed upon 72 recommendations for the clinical and molecular diagnosis and management of BWS, including comprehensive protocols for the molecular investigation, care and treatment of patients from the prenatal period to adulthood. The consensus recommendations apply to patients with Beckwith-Wiedemann spectrum (BWSp), covering classical BWS without a molecular diagnosis and BWS-related phenotypes with an 11p15.5 molecular anomaly. Although the consensus group recommends a tumour surveillance programme targeted by molecular subgroups, surveillance might differ according to the local health-care system (for example, in the United States), and the results of targeted and universal surveillance should be evaluated prospectively. International collaboration, including a prospective audit of the results of implementing these consensus recommendations, is required to expand the evidence base for the design of optimum care pathways.

Abstract
Objectives: To examine the birth prevalence of congenital macroglossia and identify demographic variables and comorbidities that may influence length of stay and cost of care. Study Design: Retrospective cross-sectional study using the Kids’ Inpatient Database 2003, 2006, 2009, and 2012. Methods: Demographics were analyzed. Linear regression modeling and multivariate analyses were performed. Results: The birth prevalence of congenital macroglossia was 4.63/100 000 births. Patients were classified as isolated (n = 349, 48.1%) or syndromic (n = 377, 51.9%). A higher incidence of isolated macroglossia was seen in females (odds ratio, OR [95% confidence interval, 95% CI]: 1.93 [1.45-2.56] and African Americans (2.02 [1.41-2.88]). Length of stay was higher for syndromic patients than for nonsyndromic patients (22.6 days [18.6-26.6] vs 7.93 days [5.95-9.90], as were inpatient costs ($3619USD [$27 628-$44 754] vs $10 168USD [$6272-$14 064]. After accounting for gender, race, location, and socioeconomic status, the presence of macroglossia alone increased length of stay by 4.07 days (0.42-7.72 days) in nonsyndromic patients and 12.02 days (3.63-20.4 days) in syndromic patients. The cost of care increased by $6207USD ($576-$11 838) among nonsyndromic newborns and $17 205USD ($374-34 035) among syndromic patients. Conclusion: The birth prevalence of congenital isolated macroglossia appears to vary by sex and race. Prolonged length of stay and increased costs are associated with both isolated macroglossia and syndromic macroglossia, even after controlling for other syndromic comorbidities.

Abstract
Beckwith-Wiedemann syndrome (BWS) is the most common pediatric overgrowth syndrome. Features characteristic of the BWS phenotype include both physical attributes, such as macroglossia, abdominal wall defects, gigantism, nevus flammeus, visceromegaly, and mid-face hypoplasia, as well as biochemical abnormalities such as hypoglycemia. It is essential for the neonatal nurse to be able to recognize BWS in the patient's early years of life because of the increased frequency of medical complications, malformations, and the increased risk of embryonic malignancies. This article focuses on the presentation of BWS as an aid to early detection.

Abstract
BACKGROUND Macroglossia causes functional deficits such as airway obstruction, drooling, phonation difficulties, and leads to protrusion of dentoalveolar structures resulting in an anterior open bite and a prognathic mandibular appearance. Macroglossia is present in the majority of patients with Beckwith-Wiedemann syndrome (BWS) and surgical treatment may be indicated. MATERIAL AND METHODS A retrospective review was conducted including BWS patients who underwent surgical tongue reduction between 2000 and 2015 at the Hospital Universitario La Paz, Madrid. RESULTS Out of 16 patients with BWS, surgery was performed in 11 cases. Tongue protrusion with open bite was the main indication for surgical treatment. Reduction glossectomy was performed using the keyhole technique. We analysed the relationship between age at surgery and evolution of open bite. Complications were minimal and satisfactory outcomes were observed with a decrease in anterior open bite. CONCLUSIONS In this study we have observed that surgical treatment in patients with BWS and open bite accompanied by macroglossia seems to provide positive results with a satisfactory outcome in dentoskeletal alterations.

Abstract
OBJECTIVES To examine the frequency of partial glossectomy performed for the indication of macroglossia in children within the United States, assessing for differences in rates of intervention across various demographics. To identify potential morbidities associated with partial glossectomy in this population and determine how such factors may influence length of stay and cost of admission following tongue reduction surgery. STUDY DESIGN Retrospective cross-sectional study. SETTING The Kids' Inpatient Database 2003, 2006, 2009, and 2012. SUBJECTS Patients under age 5 diagnosed with macroglossia who underwent partial glossectomy. METHODS Demographics were analyzed and cross tabulations, linear regression modeling, and multivariate analysis were performed. RESULTS During the four-years studied, partial glossectomy was performed in 196 children under age 5 with macroglossia. A disproportionately higher rate of intervention was seen in white children (p = 0.001), patients undergoing surgery in the mid-west (p < 0.001) and patients in the highest socioeconomic quartile (p = 0.015). Most patients underwent glossectomy in their second year of life. The average length of stay in patients who underwent partial glossectomy for macroglossia was 9.59 days (Range 1-211 days, median 3.45 days) and the average cost was $56,602 (median $16,330). CONCLUSION Partial glossectomy for macroglossia is typically performed prior to age 2 in the United States. A higher rate of intervention is seen in white children, those who have surgery in the mid-west and affluent children even when controlling for confounding variables. LEVEL OF EVIDENCE III.

Abstract
Beckwith-Wiedemann syndrome (BWS) is a rare paediatric overgrowth disorder. Associated macroglossia is a feature of many children with BWS and is felt to be a risk factor for obstructive sleep apnoea (OSA). Sleep-disordered breathing is highly variable in this population. The relationship between degree of macroglossia or other genotypic or phenotypic factors and OSA severity has not been established. The natural history of OSA in this population is unknown; a variety of conservative and surgical therapies have been used to treat OSA in children with BWS but none have been studied systematically. Tongue reduction is the mainstay of surgical therapy for macroglossia associated with BWS, but limited data are available regarding its efficacy in treating OSA or its effect on speech and swallowing. More research is needed to better identify which children with BWS are at risk for OSA and the most effective treatment for these patients.

Abstract
The macroglossia is a rare condition, congenital or acquired, characterized by hypertrophy of the lingual muscles that can cause both aesthetic and functional changes such as mandibular prognathism and malocclusion. Diagnosis is through clinical examination. Treatment consists of excision of part of the tongue and different surgical techniques have been described in the literature. The keyhole lingual resection technique has shown satisfactory results in reducing the volume and preservation of the neurovascular bundles of the tongue. This work aims to present a clinical report of true macroglossia associated with dental-skeletal discrepancies, submitted to partial glossectomy previously to orthognathic surgery.

Abstract
Airway obstruction in pediatric patients always poses a challenge for anesthesiologists. Beckwith-Wiedemann syndrome causes various abnormalities such as macroglossia and omphalocele. Patients with these abnormalities often need corrective surgeries. Management of difficult airway caused by conditions such as macroglossia in patients with this syndrome could be challenging. We encountered a case of difficult airway in an infant with Beckwith-Wiedemann syndrome. It was predicted that macroglossia might cause difficult ventilation, intubation, and extubation. Preoperative assessment and preparations for difficult airway should be considered.

Abstract
Beckwith-Wiedemann syndrome (BWS) is an overgrowth disorder in which macroglossia is one of the main signs. We investigated the long-term outcome of tongue surgery reduction (TRS) on taste and speech in patients with BWS who were more than 5 years of age and had undergone surgical anterior wedge resection of the tongue. A questionnaire was used to assess medical history and to determine some aspects of speech, taste, psychological well-being, and degree of satisfaction with regard to TRS and tongue mobility. Speech sound error pattern and degree of intelligibility were measured by a speech therapist, and taste was assessed using a validated test. The degree of both intelligibility and satisfaction with the surgery was high. There were some speech errors; especially the interdental 's', addental 't', and addental 'd' were more noticed. We conclude that anterior wedge resection is an effective technique to treat macroglossia in children with BWS, and that it has no long-term consequences for intelligibility and taste perception and only limited consequences for speech.

Abstract
Congenital macroglossia is a condition that consists in an enlarged tongue that in resting position protrudes beyond the alveolar ridge. It has been classified in two categories: true macroglossia, which occurs in congenital or acquired forms, and relative macroglossia. As this alteration may be due to different causes, its incidence is not known. It is more frequently associated to Beckwith-Wiedemann syndrome, to mucopolysaccharidosis diseases and to Pompe's disease, and it has been less frequently associated to lymphangioma, hemangioma or isolated muscular hypertrophy. Macroglossia is characterized by an enlarged and thick tongue that may have fissures and ulcers, may cause language alterations, difficulties for feeding and swallowing, sialorrhea and recurrent infections of the upper airway or even its obstruction. Its clinical evaluation must include a complete clinical chart with careful physical exploration and a pedigree of that may identify the presence or absence of a hereditary associated syndrome. Macroglossia management is complex. More than twenty different surgical options to reduce the tongue size have been proposed, however, so far there is not a general agreement in this respect. The objective of this work is to review clinical and surgical aspects related to macroglossia from the point of view of non-surgical pediatricians and genetists, addressed to the different medical specialists, including the maxillofacial surgeons involved in the management of these patients.

Abstract
UNLABELLED Beckwith-Wiedemann syndrome (BWS) is the most common (epi)genetic overgrowth-cancer predisposition disorder. Given the absence of consensual recommendations or international guidelines, the Scientific Committee of the Italian BWS Association (www.aibws.org) proposed these recommendations for the diagnosis, molecular testing, clinical management, follow-up and tumor surveillance of patients with BWS. The recommendations are intended to allow a timely and appropriate diagnosis of the disorder, to assist patients and their families, to provide clinicians and caregivers optimal strategies for an adequate and satisfactory care, aiming also at standardizing clinical practice as a national uniform approach. They also highlight the direction of future research studies in this setting. With recent advances in understanding the disease (epi)genetic mechanisms and in describing large cohorts of BWS patients, the natural history of the disease will be dissected. In the era of personalized medicine, the emergence of specific (epi)genotype-phenotype correlations in BWS will likely lead to differentiated follow-up approaches for the molecular subgroups, to the development of novel tools to evaluate the likelihood of cancer development and to the refinement and optimization of current tumor screening strategies. CONCLUSIONS In this article, we provide the first comprehensive recommendations on the complex management of patients with Beckwith-Wiedemann syndrome.

Abstract
PURPOSE OF REVIEW To discuss the current surgical management of macroglossia. RECENT FINDINGS Traditional surgical management of severe macroglossia has been with anterior wedge or keyhole resection. Long-term follow-up has been limited, and only recently have assessments been done regarding functional and aesthetic outcomes. New methods including double stellate and combination approaches have shown promise, though with limited case size reports. Addressing macroglossia in three dimensions may be the most effective way of achieving positive positional, speech and aesthetic outcomes, but comparative studies are lacking. Other causes of macroglossia, such as vascular malformations, can be managed with less aggressive measures such as laser and radio-frequency ablation. SUMMARY The aggressiveness of the management should match the severity of the symptoms. The anterior wedge resection and modified keyhole incisions are the most well studied operative strategies. Short and long-term outcome data are limited, and neither method is definitively superior. Less aggressive measures are options for less severe macroglossia. Surgical management of macroglossia should be tailored to each individual patient and in accordance to surgeon experience and expertise.

Abstract
Beckwith-Wiedemann syndrome (BWS) is a congenital growth disorder. Children born with BWS develop enlarged organs, including the tongue, a large body, and other signs. A woman with BWS was treated and followed for 30 years. Treatment consisted of tongue reduction, orthopedic and orthodontic treatment, orthognathic surgery, and retention. The patient was first treated when she was 5 years old. Her original orthodontic problems included macroglossia, anterior open bite, anterior crossbite, and a skeletal Class III jaw relationship caused by significant mandibular protrusion. The jaw-base relationships did not improve in the early preadolescent period after phase 1 of orthodontic treatment with a vertical chincap. With the growth spurt accompanying puberty, she developed a severe skeletal Class III jaw relationship and a constricted maxillary arch. Surgically assisted rapid maxillary expansion was performed at 23 years of age to correct the severe discrepancy between the maxillary and mandibular dental arch widths. Then, at 26 years, a LeFort I osteotomy, a horseshoe osteotomy, a bilateral sagittal split ramus osteotomy, and genioplasty were performed after presurgical orthodontic treatment with extraction of the mandibular first molars. Both the facial profile and the occlusion were stable after 6 years of retention. This case report discusses the result of long-term observation of a patient with BWS who underwent tongue reduction, early orthodontic treatment, and surgical-orthodontic treatment.

Abstract
The Beckwith-Wiedemann syndrome is caused by disturbed imprinting of genes at 11p15.5. Routine diagnostic testing for Beckwith-Wiedemann syndrome (BWS) includes methylation analysis of the imprinting centers ICR1 and ICR2 in DNA extracted from lymphocytes. In approximately 15% of BWS patients the diagnosis cannot be molecularly confirmed. In this study we determined the methylation status in resected tongue tissue of 11 BWS patients and compared this to the genetic defects found by routine diagnostic screening of blood lymphocytes. In all three patients with normal methylation levels in blood, aberrant methylation patterns were found in tongue tissue. In two patients a UPD was detected and the third case had hypermethylation of ICR1. This result shows that tissue specific mosaic (epi)genetic changes, not present in blood, is the underlying defect in at least a subset of BWS patients without a molecular diagnosis after standard genetic testing.

Abstract
Pathological enlargement of tongue is caused by several conditions and diseases. In several instances, surgery remains the only viable option for complete cure. Persistent bleeding, compromised neuro-motor-sensory functions during the postoperative period are the most common complaints encountered after macroglossia correction. The tongue is a muscular organ, whose complex neuroanatomy is being unraveled slowly. Various types of macroglossia resections in unique clinical situations have been proposed by several clinicians till date. There has never been unanimously accepted resection for the treatment of macroglossia. This review article attempts to preview the cosmetic and functional components for resection designs.

Abstract
Beckwith Wiedemann syndrome (BWS) is a rare, congenital overgrowth disorder that is characterized by macroglossia, anterior abdominal wall defects, visceromegaly, gigantism, and neonatal hypoglycaemia. Macroglossia may contribute to anterior open bite malocclusion with prognathism, speech articulation disturbances, drooling and the perception of intellectual disability. It was the purpose of this study to review a series of BWS patients who underwent surgical reduction of the tongue by a modified technique with respect to aesthetic and functional outcomes. Seven BWS patients, age 6 months to 21 months, had a 'stellate/anterior wedge' reduction with an anterior rotation flap and were followed up from 4 months to 9 years postoperatively. Assessment of aesthetics together with tongue morphology and mobility were recorded and a postoperative speech evaluation was performed. Minor contour deformities were present in two patients during function but all parents were satisfied with the results. The speech pathology assessment results indicated positive outcomes for speech, oral structure and function, and feeding for all children assessed. This modified technique allows for an adequate reduction of tongue volume with conservation of motor and sensory function as well as preservation of anatomical contour.
