Brazilian Academy of Paediatric Otorhinolaryngology Task Force - lingual frenulum disorders in childhood - evidence-based recommendations.

Refining the diagnosis of obstructive sleep apnoea

ObjectiveTo review the literature on the diagnosis and treatment of vestibular schwannoma. Methods: Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on vestibular schwannoma were eligible for inclusion. The American College of Physicians’ guideline grading system and the American Thyroid Association’s guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. ResultsThe topics were divided into 2 parts: (1) Diagnosis — audiologic, electrophysiologic tests, and imaging; (2) Treatment — wait and scan protocols, surgery, radiosurgery/radiotherapy, and systemic therapy. ConclusionsDecision making in VS treatment has become more challenging. MRI can diagnose increasingly smaller tumors, which has disastrous consequences for the patients and their families. It is important to develop an individualized approach for each case, which highly depends on the experience of each surgical team.

BackgroundChildhood obstructive sleep apnoea (OSA) is a prevalent disease, and reported to affect around 5% of primary school-aged children. It is also clinically important as it can lead to neurocognitive,...

Lingual frenotomy improves patient-reported outcome measures, including infant reflux and maternal nipple pain, and prolongs the nursing relationship; however, many mother-infant dyads continue to experience breastfeeding difficulty despite having had a frenotomy. Research aim: The aim of this study was to determine how incomplete release of the tethered lingual frenulum may result in persistent breastfeeding difficulties. A one-group, observational, prospective cohort study was conducted. The sample consisted of breastfeeding mother-infant (0-9 months of age) dyads ( N = 54) after the mothers self-elected completion lingual frenotomy and/or maxillary labial frenectomy following prior lingual frenotomy performed elsewhere. Participants completed surveys preoperatively, 1-week postoperatively, and 1-month postoperatively consisting of the Breastfeeding Self-Efficacy Scale-Short-Form (BSES-SF), Visual Analog Scale (VAS) for nipple pain severity, and the Revised Infant Gastroesophageal Reflux Questionnaire (I-GERQ-R). Significant postoperative improvements were reported between mean preoperative scores compared with 1-week and 1-month scores of the BSES-SF, F(2) = 41.2, p < .001; the I-GERQ-R, F(2) = 22.7, p < .001; and VAS pain scale, F(2) = 46.1, p < .001. We demonstrated that besides nipple pain, measures of infant reflux symptoms and maternal breastfeeding self-confidence can improve following full release of the lingual frenulum. Additionally, a patient population was identified that could benefit from increased scrutiny of infant tongue function when initial frenotomy fails to improve breastfeeding symptoms.

ObjectivesTo investigate the evidence on the association between ankyloglossia and obstructive sleep apnea. MethodsAn integrative literature review was carried out in the databases. Observational and interventional studies that assessed the lingual frenulum in children with sleep-disordered breathing were included. As exclusion criteria: studies in animals, in vitro, letters to the editor, expert opinions, other reviews. The selected articles were analyzed regarding the study design, sample, characterization of the lingual frenulum and sleep assessment, in addition to the main results and conclusions. ResultsNinety-seven articles were identified, but only 4 met the inclusion criteria. Two retrospective studies concluded that the untreated shortened lingual frenulum at birth is associated with obstructive sleep apnea. A prospective study concluded that there was an improvement in speech and deglutition after lingual frenectomy, in addition to improved sleep. A retrospective cohort concluded that lingual frenuloplasty combined with myofunctional therapy is effective in the treatment of snoring and mouth breathing. ConclusionThe studies included in this review contribute to corroborate the association between ankyloglossia and obstructive sleep apnea.

Purpose: to investigate what effects lingual frenotomy has on breastfeeding. Methods: based on the research question - “Is there a relationship between the improvement in breastfeeding and the lingual frenotomy?” -, a bibliographical survey was carried out in three databases, using the following descriptors: ankyloglossia, lingual frenum, breastfeeding and frenotomy. Frenotomy is a free term. Original articles with babies up to 6 months old who had difficulties breastfeeding due to ankyloglossia and who had been submitted to lingual frenotomy were chosen. An instrument was developed, containing the following information: name of the authors, year of publication, country of origin, the objective of the study, type of study, sample, main results, and conclusion. Literature Review: of the 243 articles screened, four met the inclusion criteria for this study. It was observed that, after lingual frenotomy, some changes may take place in breastfeeding patterns, such as an increase in the number of suctions and a decrease in the time of pause in between series of suctions. Conclusion: the lingual frenotomy can be an important procedure in the treatment of babies with ankyloglossia, possibly helping improve the latch and breastfeeding.

Lingual frenotomy has become an increasingly common surgical procedure, performed for a broad range of indications from birth through adulthood. This study utilizes histology to define the structure and tissue composition of the lingual frenulum and floor of mouth (FOM) fascia. En bloc specimens of anterior tongue, lingual frenulum, and FOM tissues were harvested from ten embalmed adult cadavers. An additional three fresh tissue cadaveric specimens were frozen with the tongue supported in an elevated position, to enable harvesting and paraffin embedding of the elevated lingual frenulum as a discrete specimen. All 13 specimens were prepared as ten-micron coronal sections using stains to determine the general morphology of the lingual frenulum, its relationship to neighbouring structures (Mason's Trichrome), presence of elastin fibers (Verhoeff-van Gieson), and collagen typing (Picrosirius Red). Our results have shown a submucosal layer of fascia spanning horizontally across the FOM was present in all specimens, with variability in fascial thickness and histologic composition. This FOM fascia suspends the sublingual glands, vessels, and genioglossus from its deep surface. The elevated lingual frenulum is formed by a central fold of this FOM fascia together with the overlying oral mucosa with variability in fascial thickness and composition. With tongue elevation, the fascia mobilizes to a variable extent into the fold forming the frenulum, providing a structural explanation for the individual variability in lingual frenulum morphology seen in clinical practice.

Ankyloglossia, commonly referred to as tongue tie, is an extremely rare congenital condition characterised by an abnormally short, thick, or tight lingual frenulum, resulting in restricted tongue mobility and impaired functional capacity. A broad spectrum of conditions affecting infant feeding ability—including the emergence of distinct “oral feeding phenotypes” in the newborn—is considered in this context. The aim of this review is to provide a critical analysis of current classification systems for the lingual frenulum, diagnostic methodologies, and contemporary approaches to the management of ankyloglossia in infants. To obtain information on the topic, a systematic review of the literature was conducted using available scientometric databases. Recent anatomical studies of the lingual frenulum are presented, demonstrating that it constitutes a dynamic structure composed of a median fascial fold, forming a diaphragm-like layer that spans the floor of the mouth. The authors provide a comprehensive review of classification systems, supported by illustrative material. Specifically, the Stanford classification of the labial frenulum is noted, while the Coryllos, Kotlow, and Hazelbaker classification systems for the lingual frenulum are described in detail. These systems facilitate identification of infants with ankyloglossia, differentiation of symptomatic cases, and selection of candidates most likely to benefit from lingual frenotomy. In cases of difficulty with latch or breastfeeding, the Lingual Frenulum Evaluation Protocol for Infants is highlighted as a dedicated clinical tool for assessing both the anatomical morphology and functional capacity of the lingual frenulum. The authors emphasise that current classification systems and assessment scales cannot reliably predict individual breastfeeding difficulties or unequivocally determine the indication for frenotomy; clinical decision-making must therefore incorporate objective criteria of breastfeeding efficacy. Potential complications following frenotomy are separately addressed, underscoring the necessity of a multidisciplinary evaluation of feeding difficulties and the exclusion or correction of alternative aetiological factors prior to intervention. Several objective assessment tools for infant feeding function are presented: the Neonatal Oral-Motor Assessment Scale (NOMAS), the Infant Breastfeeding Assessment Tool (IBFAT), the Supports for Attachment and Infant Breastfeeding Scale (SAIB), and the Preterm Infant Breastfeeding Behavior Scale (PIBBS). Among these, the LATCH scale is discussed as one of the most clinically practical instruments. Based on the analysis of contemporary approaches to ankyloglossia in infants, the authors conclude that clear, universally accepted indications for frenotomy remain lacking; consensus is absent regarding procedural technique, anaesthetic modality, and optimal timing of intervention. Current national clinical protocols and standards for medical care in Ukraine provide no definitive guidance for managing this condition. In clinical practice, the implementation of targeted lactation support measures and individualised feeding strategies may enhance breastfeeding efficacy and reduce the need for invasive procedures associated with ankyloglossia.

Although the interference of tongue-tie with breastfeeding is a controversial subject, The use of lingual frenotomy has been widely indicated by health professionals. Objective: To observe changes in breastfeeding patterns after lingual frenotomy concerning the number of sucks, pause length between groups of sucking and mother's complaints.Material and Methods : Oral yes/no questions about breastfeeding symptoms and sucking/swallowing/breathing coordination were answered by the mothers of 109, 30 day old infants. On the same day the infants had their lingual frenulum assessed by administering a lingual frenulum protocol. After the assessment, all tongue-tied infants were referred for frenotomy; nevertheless, only 14 underwent the surgery. Of the 109 infants, 14 infants who did not have frenulum alterations were included as controls. Birth order and gender were the criteria for recruiting the control group. The tongue-tied infants underwent lingual frenotomy at 45 days of age. At the conclusion of the frenotomy, the infants were breastfed. At 75 days old, both groups – control and post-frenotomy – were reassessed. Before the reassessment the same oral yes/no questions were answered by the mothers of the 14 infants who underwent frenotomy. The mothers of the control group answered the questionnaire only at the time of the first assessment. Data were subjected to statistical analysis.Results : After frenotomy, the number of sucks increased and the pause length between sucking decreased during breastfeeding. The controls maintained the same patterns observed in the first assessment. From the questionnaire answered by the mothers of the 14 tongue-tied infants, at 30 days and 75 days, we observed that the symptoms concerning breastfeeding and sucking/swallowing/breathing coordination were improved after lingual frenotomyConclusions : after lingual frenotomy, changes were observed in the breastfeeding patterns of the the tongue-tied infants while the control group maintained the same patterns. Moreover, all symptoms reported by the mothers of the tongue-tied infants had improved after frenotomy.

ObjectivesTo provide an overview of the main evidence-based recommendations for the diagnosis of hearing loss in children and adolescents aged 0–18 years. MethodsTask force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on childhood hearing loss were eligible for inclusion. The American College of Physicians’ guideline grading system and the American Thyroid Association’s guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. ResultsThe topics were divided into 2 parts: (1) treatment of sensorineural hearing loss: individual hearing aids, bilateral cochlear implants, cochlear implants in young children, unilateral hearing loss, and auditory neuropathy spectrum disorder; and (2) treatment of conductive/mixed hearing loss: external/middle ear malformations, ventilation tube insertion, and tympanoplasty in children. ConclusionsIn children with hearing loss, in addition to speech therapy, Hearing AIDS (HAs) or implantable systems may be indicated. Even in children with profound hearing loss, both the use of HAs and behavioral assessments while using the device are important.

ObjectiveTo make evidence-based recommendations for the treatment of Single-Sided Deafness (SSD) in children and adults. MethodsTask force members were instructed on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on SSD were eligible for inclusion. The American College of Physicians’ guideline grading system and the American Thyroid Association’s guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. ResultsThe topics were divided into 3 parts: (1) Impact of SSD in children; (2) Impact of SSD in adults; and (3) SSD in patients with temporal bone tumors. ConclusionsDecision-making for patients with SSD is complex and multifactorial. The lack of consensus on the quality of outcomes and on which measurement tools to use hinders a proper comparison of different treatment options. Contralateral routing of signal hearing aids and bone conduction devices can alleviate the head shadow effect and improve sound awareness and signal-to-noise ratio in the affected ear. However, they cannot restore binaural hearing. Cochlear implants can restore binaural hearing, producing significant improvements in speech perception, spatial localization of sound, tinnitus control, and overall quality of life. However, cochlear implantation is not recommended in cases of cochlear nerve deficiency, a relatively common cause of congenital SSD.

ObjectiveTo review key evidence-based recommendations for the diagnosis and treatment of peripheral facial palsy in children and adults. MethodsTask force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on peripheral facial palsy were eligible for inclusion. The American College of Physicians’ guideline grading system and the American Thyroid Association’s guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. ResultsThe topics were divided into 2 main parts: (1) Evaluation and diagnosis of facial palsy: electrophysiologic tests, idiopathic facial palsy, Ramsay Hunt syndrome, traumatic peripheral facial palsy, recurrent peripheral facial palsy, facial nerve tumors, and peripheral facial palsy in children; and (2) Rehabilitation procedures: surgical decompression of the facial nerve, facial nerve grafting, surgical treatment of long-term peripheral facial palsy, and non-surgical rehabilitation of the facial nerve. ConclusionsPeripheral facial palsy is a condition of diverse etiology. Treatment should be individualized according to the cause of facial nerve dysfunction, but the literature presents better evidence-based recommendations for systemic corticosteroid therapy.

ObjectivesTo review and provide evidence-based recommendations for the diagnosis and treatment of otosclerosis. MethodsTask force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on otosclerosis were eligible for inclusion. The American College of Physicians’ guideline grading system and the American Thyroid Association’s guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. ResultsThe topics were divided into 2 parts: 1) Diagnosis – audiologic and radiologic; 2) Treatment – hearing AIDS, pharmacological therapy, stapes surgery, and implantable devices – bone-anchored devices, active middle ear implants, and Cochlear Implants (CI). ConclusionsThe pathophysiology of otosclerosis has not yet been fully elucidated, but environmental factors and unidentified genes are likely to play a significant role in it. Women with otosclerosis are not at increased risk of worsening clinical condition due to the use of contraceptives or during pregnancy. Drug treatment has shown little benefit. If the patient does not want to undergo stapedotomy, the use of hearing aids is well indicated. Implantable systems should be indicated only in rare cases, and the CI should be indicated in cases of profound deafness.

ObjectivesTo provide an overview of the main evidence-based recommendations for the diagnosis of hearing loss in children and adolescents aged 0 to 18 years. MethodsTask force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on childhood hearing loss were eligible for inclusion. The American College of Physicians’ guideline grading system and the American Thyroid Association’s guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. ResultsThe evaluation and diagnosis of hearing loss: universal newborn hearing screening, laboratory testing, congenital infections (especially cytomegalovirus), genetic testing and main syndromes, radiologic imaging studies, vestibular assessment of children with hearing loss, auditory neuropathy spectrum disorder, autism spectrum disorder, and noise-induced hearing loss. ConclusionsEvery child with suspected hearing loss has the right to diagnosis and appropriate treatment if necessary. This task force considers 5 essential rights: (1) Otolaryngologist consultation; (2) Speech assessment and therapy; (3) Diagnostic tests; (4) Treatment; (5) Ophthalmologist consultation.

This systematic review provides supporting evidence for the accompanying clinical practice guideline on the referral of adults with obstructive sleep apnea (OSA) for surgical consultation. The American Academy of Sleep Medicine commissioned a task force of experts in sleep medicine. A systematic review was conducted to identify studies that compared the use of upper airway sleep apnea surgery or bariatric surgery to no treatment as well as studies that reported on patient-important and physiologic outcomes pre- and postoperatively. Statistical analyses were performed to determine the clinical significance of using surgery to treat obstructive sleep apnea in adults. Finally, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) process was used to assess the evidence for making recommendations. The literature search resulted in 274 studies that provided data suitable for statistical analyses. The analyses demonstrated that surgery as a rescue therapy results in a clinically significant reduction in excessive sleepiness, snoring, blood pressure (BP), apnea-hypopnea index (AHI), respiratory disturbance index (RDI), and oxygen desaturation index (ODI); an increase in lowest oxygen saturation (LSAT) and sleep quality; and an improvement in quality of life in adults with OSA who are intolerant or unaccepting of positive airway pressure (PAP) therapy. The analyses demonstrated that surgery as an adjunctive therapy results in a clinically significant reduction in optimal PAP pressure and improvement in PAP adherence in adults with OSA who are intolerant or unaccepting of PAP due to side effects associated with high pressure requirements. The analyses also demonstrated that surgery as an initial treatment results in a clinically significant reduction in AHI/RDI, sleepiness, snoring, BP, and ODI and an increase in LSAT in adults with OSA and major anatomical obstruction. Analysis of bariatric surgery data showed a clinically significant reduction in BP, AHI/RDI, sleepiness, snoring, optimal PAP level, BMI, and ODI and an increase in LSAT in adults with OSA and obesity. Analyses of very limited evidence suggested that upper airway surgery does not result in a clinically significant increase in risk of serious persistent adverse events and suggested that bariatric surgery may result in a clinically significant risk of iron malabsorption that may be managed with iron supplements. The task force provided a detailed summary of the evidence along with the quality of evidence, the balance of benefits and harms, patient values and preferences, and resource use considerations.
