The effect of frenectomy for tongue-tie, lip-tie, or cheek-tie on breastfeeding outcomes: A systematic review of articles over time and suggestions for management.

OBJECTIVE: Tongue-tie, or ankyloglossia, is a common condition characterized by an abnormally short or tight lingual frenulum and is known to cause breastfeeding difficulties, leading to damage to the nipple, early discontinuation of breastfeeding, and delayed infant growth. In addition to tongue-tie, abnormal frenulums such as the labial frenulum and buccal frenulum can cause lip-tie and cheek-tie, respectively. While both of these conditions have been reported to potentially cause similar issues related to breastfeeding as tongue-tie, limited research has been conducted to understand their effects and how we should treat these conditions. METHODS: In this systematic review, we conducted a comprehensive search of MEDLINE to analyze the trend in publications of all three of these conditions and their impact on breastfeeding for the past 36 years. Keywords included, "tongue-tie", "lip-tie", "cheek-tie", and "breastfeeding outcomes". RESULTS: We found that publications describing the effect of only tongue-ties on breastfeeding have increased exponentially over time while less focus has been on other oral ties. It was also discovered that the majority of studies describing only lip-tie or tongue-tie were editorials, commentary, perspectives, or consensus statements. Finally, we found that articles describing more than one abnormal frenulum were more likely to be cited and articles describing tongue-tie only were published in the highest impact factor journals. CONCLUSION: This study revealed a significant increase in publications discussing tongue-tie and a lack of research on lip-tie and cheek-tie in relation to breastfeeding. The findings highlight the need for more comprehensive research and attention to lip-tie and cheek-tie, as well as standardized diagnostic criteria. Ongoing debate surrounding management of these conditions stem from the lack of investigations on the impact of these abnormal frenulums and outcomes post-frenectomy. Future high-quality studies, specifically prospective cohort studies and randomized controlled trials, are necessary to provide more robust evidence and guide clinical practice.

Aging, prevalence and risk factors of MRI-visible enlarged perivascular spaces.

BACKGROUND AND PURPOSE: Cerebral small vessel disease (CSVD) increases with age and is associated with stroke and cognitive decline. Enlarged Perivascular Spaces (ePVS) is an emerging marker of CSVD, but its prevalence over the life span remain unclear. We characterized the age and sex-specific prevalence of ePVS and relation to age-specific risk factors, in a large community-based sample. METHODS: We included 3,710 Framingham Heart Study participants with available brain MRI (average age 61.4±14.6, 46% men). ePVS burden was rated in the centrum semiovale (CSO) and basal ganglia (BG) regions. Individual vascular risk factors were related to ePVS burden in the CSO, BG, and mixed CSO-BG regions using multivariable adjusted ordinal logistic regression analysis. RESULTS: Severe ePVS prevalence increased with age in men and women, and paralleled increase in vascular risk factors, and prevention treatment use. Older age, hypertension (and resulting higher treatment use), higher systolic and diastolic blood pressure, and smoking were associated with higher burden of ePVS in the CSO, BG and mixed regions. CONCLUSIONS: Our observations reinforce the hypothesis that ePVS may be a marker of aging-driven brain vascular pathologies, and its association with vascular risk factors support their role as CSVD imaging biomarker.
