The efficacy of tongue resection in treatment of symptomatic macroglossia in the child

The Utility of Early Tongue Reduction Surgery for Macroglossia in Beckwith-Wiedemann Syndrome

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.

Surgical Outcomes of Patients with Beckwith-Wiedemann Syndrome

PURPOSE

The purpose of this study was to evaluate treatment and surgical outcomes of patients of Beckwith-Wiedemann Syndrome (BWS) treated at a tertiary children's hospital.

METHODS

A retrospective review of infants evaluated at Texas Children's Hospital for BWS from August 2000 to December 2016 was performed. Data collected included demographic information, clinical presentation, genetic evaluation, fetal imaging, operative treatment, and outcomes.

RESULTS

Forty-seven children with a diagnosis of BWS were identified. Sixty-four percent (n=30) had a genetic mutation in an imprinting domain of chromosome 11p15. Thirty-two patients (68%) underwent at least one operation related to BWS with a median of 2 [range: 0-8] surgical procedures per patient. Sixteen underwent omphalocele repair, 12 had partial glossectomies-, 7 underwent surgeries related to hemihypertrophy, and 6 had resection of an embryonal tumor (two adrenal cortical adenoma, one Wilms' tumor, two hepatoblastoma). Overall, survival was 100% with feeding difficulty (47%) being the most frequent complication.

CONCLUSION

A substantial number of patients with Beckwith-Wiedemann Syndrome will require surgery. However, overall outcomes are similar between those that require surgery and those that do not.

Partial glossectomy as an auxiliary method to orthodontic treatment of dentofacial deformity

INTRODUCTION

 macroglossia is a condition which influences the size and shape of the teeth employed due to the forces on teeth.

OBJECTIVE

 To establish bases for the indication of partial glossectomy associated with orthodontic treatment and surgical dento-facial deformity in patients without tumors and Down syndrome as a cause of macroglossia.

CASE REPORTS

 Three patients underwent orthognathic surgery associated with partial glossectomy under general anesthesia. All patients had macroglossia relative and underwent clinical assessment taking into account the respiratory function, swallowing and speech deficits and radiological evaluation. The technique used consist of segmental resection along the median raphe of the tongue and suture by planes. We used rigid skeletal fixation with titanium plates and screws so that patients could stay without intermaxillary block in the immediate postoperative period. Were followed over five years. The symptoms regressed completely and all skeletal segments remained stable.

DISCUSSION

 The decision to refer the patient to partial glossectomy should be based on the volume of the language, mobility, position, function, symptoms, speech intelligibility, skeletal anterior open bite, interference in orthodontic treatment, drooling, swallowing and tongue trauma applicant.

A multidisciplinary approach to the treatment of oral manifestations associated with Beckwith-Wiedemann syndrome: a long-term case report

BACKGROUND

Beckwith-Wiedemann syndrome (BWS) is a congenital disorder that involves a somatic overgrowth during the patient's first years of life. Exomphalos, macroglossia and gigantism are the main clinical symptoms.

CASE DESCRIPTION

The authors describe a 15-year follow-up in a patient with BWS. They focus on a multidisciplinary approach to treating the patient's oral manifestations from age 9 months. The approach included an initial physiotherapy treatment, a partial glossectomy, a first phase of orthopedic treatment with a tongue crib and chin cap, and a second phase of orthodontic treatment with an edgewise appliance.

CLINICAL IMPLICATIONS

To obtain long-term positive and stable results, an appropriate treatment plan for patients with BWS and dentoskeletal alterations, including macroglossia, requires surgical tongue reduction when the patient is young, combined with physiotherapeutic phases and orthopedic and orthodontic treatment.

Psychosocial, feeding, and drooling outcomes in children with Beckwith Wiedemann syndrome following tongue reduction surgery

OBJECTIVE

Macroglossia is a common feature of Beckwith Wiedemann Syndrome (BWS). Tongue reduction surgery (TRS) is advocated to overcome, or reduce, the secondary effects of macroglossia. Macroglossia may affect a child's cosmetic appearance, feeding, and drooling function. However, no study has systematically reported on feeding, drooling, or psychosocial outcomes preoperatively and postoperatively in this group. This study aimed to describe the presurgical and postsurgical psychosocial, feeding, and drooling outcomes of children with macroglossia associated with BWS and to determine the effect of TRS on these areas.

DESIGN

Clinical cohort study.

PARTICIPANTS

Ten consecutively admitted children with BWS (age at surgery from 9 months to 4 years, 9 months [4;9]; mean, 2;7) were assessed preoperatively, 3 months postoperatively, and at long-term follow-up.

MAIN OUTCOME MEASURES

A parental report questionnaire, the Brodsky drooling scale, and a feeding rating scale.

RESULTS

Parents reported that macroglossia had a negative impact cosmetically that was ameliorated following surgery. Macroglossia caused a range of feeding difficulties presurgically by preventing lip seal and bolus manipulation during the oral preparatory phase. Excessive drooling was present in all cases presurgically. This resolved partially across the group postsurgically, with almost complete recovery at longer-term follow-up assessment.

CONCLUSIONS

Presurgically, children show a common profile of feeding and drooling impairment with negative effects on cosmetic appearance. Our preliminary results demonstrate that TRS has a positive impact on these features with good outcomes for children with BWS.

[Macroglossia and Beckwith-Wiedemann syndrome]

INTRODUCTION

In 1963 Beckwith presented a report on the first patient with extreme cytomegaly of adrenal cortex, hyperplasia of kidneys and pancreas and Leydig cell hyperplasia. Wiedemann completed description of the new syndrome by adding umbilical hernia and macroglossia. The diagnosis is made based on the clinical signs of omphalocele or some other umbilical deformity, macroglossia, congenital asymmetry, visceromegaly (liver, pancreas, and kidneys).

CASE OUTLINE

A 16-month-old male child was admitted for examination because of macroglossia. He underwent examination on several occasions by an endocrinologist due to recurrent hypoglycaemic crisis. The patient was observed by a paediatric neurophysicatrist for disorders of mental development. Hypoglycaemia, muscular hypotonia of the anterior abdominal wall with umbilical hernia and macroglossia were observed by clinical examination. Inratraoral examination revealed macroglossia with microstomia, suckling and swallowing difficulties, hypotonia of the perioral muscles with increased salivation. It was therefore decided to perform surgical reduction of the prominent tongue and develop good condition for nutrition, speech function and the development of orofacial system.

CONCLUSION

The diagnosis of macroglossia is based on subjective clinical criteria such as the morphology and amount of protrusion of the tongue, difficulty in articulating sounds, breathing, and hypersalivation. Some authors have suggested that the tongue size may be analyzed radiographically with a cephalogram. Treatment of macroglossia is controversial because of the absence of objective clinical criteria.

Long-term impact of tongue reduction on speech intelligibility, articulation and oromyofunctional behaviour in a child with Beckwith-Wiedemann syndrome

The purpose of the present case study was to determine the long-term impact of partial glossectomy (using the keyhole technique) on overall speech intelligibility and articulation in a Dutch-speaking child with Beckwith-Wiedemann syndrome (BWS). Furthermore the present study is meant as a contribution to the further delineation of the phonation, resonance, articulation and language characteristics and oral behaviour in a child with BWS. Detailed information on the speech and language characteristics of children with BWS may lead to better guidance of pediatric management programs. The child's speech was assessed 9 years after partial glossectomy with regard to ENT characteristics, overall intelligibility (perceptual consensus evaluation), articulation (phonetic and phonological errors), voice (videostroboscopy, vocal quality), resonance (perceptual, nasometric assessment), language (expressive and receptive) and oral behaviour. A class III malocclusion, an anterior open bite, diastema, overangulation of lower incisors and an enlarged but normal symmetric shaped tongue were present. The overall speech intelligibility improved from severely impaired (presurgical) to slightly impaired (5 months post-glossectomy) to normal (9 years postoperative). Comparative phonetic inventory showed a remarkable improvement of articulation. Nine years post-glossectomy three types of distortions seemed to predominate: a rhotacism and sigmatism and the substitution of the alveolar /z/. Oral behaviour, vocal characteristics and resonance were normal, but problems with expressive syntactic abilities were present. The long-term impact of partial glossectomy, using the keyhole technique (preserving the vascularity and the nervous input of the remaining intrinsic tongue muscles), on speech intelligibility, articulation, and oral behaviour in this Dutch-speaking child with congenital macroglossia can be regarded as successful. It is not clear how these expressive syntactical problems demonstrated in this child can be explained. Certainly they are not part of a more general developmental delay, hearing problems or cognitive malfunctioning. To what extent the presence of expressive syntactical problems is a possible aspect of the phenotypic spectrum of children with BWS is subject for further research. Multiple variables, both known and unknown can affect the long-term outcome after partial glossectomy in a child with BWS. The timing and type of the surgical technique, hearing and cognitive functioning are known variables in this study. But variables such as children's motivation, the contribution of the motor-oriented speech therapy, the parental articulation input and stimulation and other family, school and community factors are unknown and are all factors which can influence speech outcome after partial glossectomy. Detailed analyses in a greater number of subjects with BWS may help further illustrate the long-term impact of partial glossectomy.

Morphologic and histologic outcomes of tongue reduction surgery in an animal model

OBJECTIVE

To describe the effect of anterior tongue reduction surgery on tongue size, morphology, and histology.

DESIGN

Prospective experiment.

MATERIALS

Twenty-two 12-week-old Yucatan minipigs.

METHODS

Six sibling pairs had tongue reduction (Group B) or sham surgery (Group A), and underwent euthanasia the day of surgery. Five sibling pairs had tongue reduction (Group D) or sham surgery (Group C), and were raised for four weeks. Data collected included changes in tongue morphology, histology, and animal response to surgery.

RESULTS

All animals tolerated surgery and maintained their weight. Tongue size was uniformly reduced in all animals as compared to sham surgery. Tongue reduction was stable long term in Group D. All animals had normal wound healing and neurovascular structure preservation. Fibrosis occurred at the repair site.

CONCLUSION

Midline tongue reduction resulted in uniform tongue reduction in all dimensions and volume, without damaging neurovascular structures. Localized fibrosis is a sequela of healing.

Long-term outcomes of surgical tongue reduction in Beckwith-Wiedemann syndrome

BACKGROUND

Surgical tongue reduction is often performed in Beckwith-Wiedemann syndrome when macroglossia results in abnormal tongue function or cosmesis; however, no published studies have examined the long-term outcomes of this procedure.

METHODS

Patients older than 18 years with Beckwith-Wiedemann syndrome who had previously undergone surgical tongue reduction at the Royal Children's Hospital in Melbourne underwent assessment of speech and tongue function, mobility, sensation, and cosmesis. These assessments were performed by questionnaire on 11 subjects and by formal medical and speech pathology review in four of these 11 subjects.

RESULTS

Eleven patients aged 19 to 31 years completed responses by means of questionnaire. The most common self-reported abnormalities were continued disproportionate tongue bulk (91 percent), abnormal tongue appearance (82 percent), specific speech sound errors (73 percent), and a short tongue tip (55 percent). Formal assessments investigated speech, swallowing, taste, and tongue mobility in four quite different subjects. One of these four subjects had no detectable deficits in tongue function. All 11 patients were of normal intelligence and did not report significant difficulties in their day-to-day life that were attributable to their macroglossia or tongue reduction surgery.

CONCLUSIONS

Pediatric patients with symptomatic macroglossia requiring surgical tongue reduction may not achieve complete normality in tongue function and appearance in adulthood. It is important that surgical tongue reduction addresses the global nature of the macroglossia and aims to retain a tapered tongue tip with length sufficient to permit normal tongue movements.

Treatment of macroglossia in Beckwith-Wiedemann syndrome

A case of macroglossia caused by Beckwith Wiedemann syndrome is reported. Beckwith-Wiedemann Syndrome is an overgrowth disorder characterized by a constellation of congenital anomalies. The most common manifestations are omphalocele, macroglossia, gigantism, and visceromegaly. When the tongue reaches a huge dimension, clinical symptoms are represented by dysphagia, alterations in speech, difficulty in chewing, obstruction of the upper airways, and psychologic consequences derived from the patient's physical appearance. The authors describe the surgical strategy performed in the reported case.

Personality analysis of patients complaining of sialorrhoea

BACKGROUND

Sialorrhoea, the symptom of apparent excessive secretion of saliva is a relatively uncommon complaint. Some authors consider that in the absence of clinical findings, then these patients have a psychiatric disorder masquerading as a physical illness. However, there is little evidence in the literature to support this conclusion and a detailed psychological assessment of this population has not previously been reported.

METHODS

In total, 18 patients and 18 age- and sex-matched controls were studied. All had a history of a complaint of excess salivation in the absence of any oral mucosal or systemic abnormality. All patients completed an Eysenck Personality Questionnaire.

RESULTS

There were no differences in the extroversion of psychoticism scores between the study and control group. However, the result showed significant increases in the neuroticism and Lie Scale score in the patient group.

CONCLUSIONS

The overall results of this study indicate that the complaint of sialorrhoea in otherwise healthy individuals does not have an organic basis and suggest that sialorrhoea is associated with high levels of neuroticism and a tendency to dissimulate.

Acute exacerbation of macroglossia leading to necrosis of the anterior third of the tongue

Macroglossia is defined as an enlarged tongue that protrudes beyond the teeth or the alveolar ridge in the resting position. Macroglossia may be classified into generalised and localised based on the extent of tongue involvement. Each of these groups can be subdivided into congenital, inflammatory, traumatic, metabolic and neoplastic lesions [Myer III CM, Hotaling AJ, Reilly JS. The diagnosis and treatment of macroglossia in children. Ear Nose Throat J 1986;65:444-8]. The congenital causes are vascular anomalies such as haemangioma and lymphovenous malformations. We report the case of a large lymphovenous malformation of the tongue in a 17 month old child who developed an acute exacerbation of macroglossia following trauma. This eventually led to necrosis of the anterior third of his tongue requiring a partial glossectomy.

Stimulated parotid salivary flow rate in patients with Down syndrome

Saliva is essential for oral defense against infections. Decreased salivary secretion may result in increased dental caries, oral mucosal changes, an altered sense of taste, difficulty in swallowing, and oral pain. A review of the literature reveals sporadic and contradictory reports on the use of sialometry and sialochemistry to explain the role of saliva in the oral health and well-being of subjects with Down syndrome. The present study documents parotid gland saliva secretion at different ages in a group of subjects with Down syndrome. Saliva was collected from 39 patients 11 to 62 years old, by means of a parotid salivary gland cup and under standardized conditions of stimulated secretion. The rate of salivary secretion in the entire group of patients with Down syndrome was lower than that of healthy controls and lower in the older study group compared with the younger group. Institutionalized subjects or those living in hostel-like apartments had a lower secretion rate than those living at home. No difference in salivary flow was found between those patients with Down syndrome with normal thyroid output and those with hypothyroidism who were receiving replacement therapy. In a four-way ANOVA with flow as the dependent variable and Down syndrome, hypothyroidism, institutionalization, and age as factors, Down syndrome was found to be the only variable significantly related to flow (p = 0.017). Our findings indicate that stimulated parotid salivary hypofunction in Down syndrome subjects is mainly related to their genetic disorder.

Technique for uniform reduction of macroglossia

Congenital macroglossia is a relatively uncommon condition characterised by enlargement of the tongue disproportionate to the rest of the dentoalveolar structures. It may cause significant symptoms in children. It is important to achieve uniform global reduction of the enlarged tongue for functional as well as aesthetic reasons. It is also important to preserve the mobility and sensation of the tongue. We describe a technique which meets these criteria.
