AI Article Synopsis

  • The study investigates the relevance of tethered maxillary frenulum (lip-tie) in newborns and the necessity of surgical intervention, as previous research on this topic has been lacking.
  • The research included 61 infants with lip-tie and compared them to 66 age-matched controls, revealing that those with tethered frenula experienced less nipple pain during breastfeeding and had no significant differences in other feeding or oral development issues.
  • The conclusion indicates that lip-tie may not lead to increased breastfeeding challenges or oral disorders, suggesting that clinicians should reconsider the need for surgical procedures in these cases.

Article Abstract

Background: The clinical significance of lip-tie, or a tethered maxillary frenulum, remains under debate. Clinicians and parents are often perplexed when deciding whether procedures available to relieve a seemingly tight or severe maxillary frenulum are needed.

Purpose: No previous studies have assessed the consequences of not subjecting a tethered maxillary frenulum in newborns to surgical intervention. This study aimed to contribute the first prospective trial on this topic with a relatively extended followup of these newborn infants.

Methods: This prospective observational questionnaire-based cohort trial was performed in a community setting and aimed to determine whether lip-tie is associated with an increased likelihood of eventual feeding or oral disorders.

Results: The convenience sample comprised of 61 consecutively arriving infants with concomitant tethered frenula who were treated at the clinic for various reasons. This cohort was compared with a random sample of 66 age-matched children for a mean follow-up period of 6.42 years. Infants undergoing oropharyngeal procedures were excluded. Awareness of a deviation in oral structures was reported by 18% of the study group versus 0% of the controls. Mothers participating in the study group (24.6%) less frequently recalled painful nipples or discomfort during breastfeeding than those in the control group (47.0%) (P<0.01). There were no intergroup differences in other types of feeding difficulty, dental hygiene, pronunciation, or speech development.

Conclusion: Our findings suggest that a tethered labial frenulum is not associated with an increase in breastfeeding disturbances or oral disorders. These data encourage clinicians to question the need to intervene in cases of tethered maxillary frenula.

Ankyloglossia is a congenital, abnormally short, thickened, or tight lingual frenulum that restricts tongue mobility, which may impair the development of the lower face morphology, namely the occlusion and skeleton. The aim of this study was to evaluate whether and how the lingual frenotomy benefits the occlusion and lower face skeleton development. The authors, independently and in duplication, performed searches of PubMed, Cochrane Library, Medline, Web of Science, and Embase, introducing the following keywords: tongue tie, ankyloglossia, and short lingual frenum/frenulum, combined with malocclusion, lower face skeleton, and hyoid bone.

Sleep Medicine Division, Department of Psychiatry and Behavioral Sciences, Stanford University, School of Medicine, Redwood City, California, USA.

Purpose: This narrative review aims to elucidate the anatomical features of sleep-disordered breathing (SDB) in children. By identifying key structures and intervening proactively, we seek to alter craniofacial growth patterns and improve functional outcomes for SDB children.

Methods: The literature on pediatric sleep-disordered breathing (PSDB), pediatric obstructive sleep apnea (OSA), anatomical predispositions, and the relationship between skeletal deformity and PSDB was examined using PubMed and Google Scholar databases, covering studies from 2006 to 2024.

Aim: This case report aims to describe a rare congenital lesion of the incisive papilla with a high labial frenulum attachment, clinically mimicking congenital epulis but histopathologically diagnosed as an oral leiomyomatous hamartoma.

Background: Oral leiomyomatous hamartoma is a very rare congenital lesion, mainly appearing on the median anterior maxilla/incisive papilla and tongue.

Case Description: This clinical paper is about a rare lesion in a 6-year-old female child whose parents reported to the department with the complaint of slow-growing soft tissue overgrowth between the front teeth of the upper jaw, present since birth.
