Evaluation of keyhole-pattern reduction glossoplasty for macroglossia in beckwith-wiedemann syndrome: A multidimensional analysis of postoperative course and outcomes

The aim of this study was to evaluate the postoperative course and long-term functional and aesthetic outcomes in patients with Beckwith-Wiedemann syndrome (BWS) following surgical reduction of macroglossia, using multiple questionnaires. Patients with BWS who underwent keyhole reduction for macroglossia were included in this study. The postoperative course for each patient was recorded, and multiple questionnaires were administered to evaluate aesthetic concerns, oral incompetence or feeding difficulties, sleep-disordered breathing symptoms, and speech. Nine patients underwent ten reduction glossoplasty surgeries. The mean age at surgery was 22 months. The postoperative course for each case was uneventful, except for one patient who had wound dehiscence. The questionnaires revealed significant improvements in tongue appearance, feeding, drooling, facial appearance, and psychosocial outcomes. There was also a significant reduction in sleep-disordered breathing symptoms after surgery. Keyhole reduction glossoplasty is a safe and effective procedure for the treatment of macroglossia in BWS patients, with excellent functional and aesthetic outcomes and a low complication rate.

Beckwith-Widemann Macroglossia: The Role of Surgical Tongue Reduction

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.

Oral Health-Related Quality of Life among Children and Adolescents with Beckwith–Wiedemann Syndrome in Northern Italy

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.

Anterior "W" Tongue Reduction for Macroglossia in Beckwith-Wiedemann Syndrome

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.

Tongue Reduction for Macroglossia

INTRODUCTION

Macroglossia is a term used to describe a large tongue which protrudes outside of the mouth while in a resting position (Balaji, 2013). It is a cardinal sign in children with Beckwith-Wiedemann syndrome and can also be found in children with Down syndrome and Klippel-Trenaunay-Weber syndrome. Macroglossia can lead to airway and feeding difficulties, as well as problems with speech, drooling, and cosmesis. We present a review of tongue reduction operations performed for macroglossia over a 10-year period in Northern Ireland.

METHODS

We performed a retrospective review of the medical notes of those children identified to have undergone a tongue reduction procedure in the regional pediatric hospital. We reviewed the presenting symptoms and concerns, the operative technique used, postoperative outcomes, and follow up. Outcomes data included improvements in symptoms, complications, and the need for revision procedures.

RESULTS

Six children underwent tongue reduction procedures over a 10-year period. Age range at time of surgery was between 4 months to 10 years 3 months. Five children had an underlying diagnosis of Beckwith-Wiedemann syndrome and 1 child had Down syndrome. One child underwent a second tongue reduction for mild tongue protrusion at the 5-year follow up. There were no complications in relation to tongue reduction surgery for any of the children and importantly, there were no airway complications in our series. All patients were found to have improved feeding, better tongue position in the oral cavity, reduced drooling, and better speech development following surgery.

CONCLUSION

Symptomatic macroglossia requiring a tongue reduction procedure is relatively rare and these procedures are, therefore, uncommonly performed. Despite the rarity of this procedure, when it is required, it can be life saving for some infants and children, and life altering for the remainder. Improvements in airway, feeding, speech, and psychosocial wellbeing are the desired outcomes with this procedure. Throughout our 10-year series we have found it to be a relatively safe procedure but potentially anesthetically challenging. We have demonstrated both good short and long-term outcomes for these children.

Long-term longitudinal evalutation of mandibular growth in patients with Beckwith-Wiedemann Syndrome treated and not treated with glossectomy

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.
