Objectives
There is debate among otolaryngologists and other practitioners about whether upper lip tie contributes to difficulty with breastfeeding and whether upper lip tie and ankyloglossia are linked. Our objectives were to evaluate the anatomy of the upper lip (maxillary) frenulum, to determine if the visual anatomy of the upper lip has an effect on breastfeeding, and to determine whether the occurrence of lip tie and tongue tie are correlated.
Methods
A prospective cohort study of 100 healthy newborns was examined between day of life 3–7. Surveys were completed by the mother at the time of the initial exam and 2 weeks later. The maxillary frenulum was graded based on the Stanford and Kotlow classifications by two independent reviewers. Inter‐rater reliability and relationships between tongue tie, lip tie, and the infant breastfeeding assessment tool (IBFAT) were calculated.
Results
Inter‐rater reliability showed fair agreement (κ = 0.302) using the Kotlow scale and better agreement using the Stanford classification (κ = 0.458). There was no correlation between the upper lip tie classification and breastfeeding success score. Lastly, there was a modest inverse correlation in the degree of tethering for the tongue and lip.
Conclusions
There was no correlation between maxillary frenulum grade and comfort with breastfeeding, pain scores, or latch. There was also no relationship between tip to frenulum length (tongue tie) and visualized lip anatomy, suggesting that tongue tie and lip tie may not cluster together in infants.

Objective
To compare supraglottoplasty versus non-surgical treatment in children with laryngomalacia and mild, moderate and severe obstructive sleep apnoea.
Methods
Patients were classified based on their obstructive apnoea hypopnoea index on initial polysomnogram, which was compared to their post-treatment polysomnogram.
Results
Eighteen patients underwent supraglottoplasty, and 12 patients had non-surgical treatment. The average obstructive apnoea hypopnoea index after supraglottoplasty fell by 12.68 events per hour (p = 0.0039) in the supraglottoplasty group and 3.3 events per hour (p = 0.3) in the non-surgical treatment group. Comparison of the change in obstructive apnoea hypopnoea index in the surgical versus non-surgical groups did not meet statistical significance (p = 0.09).
Conclusion
All patients with laryngomalacia and obstructive sleep apnoea had a statistically significant improvement in obstructive apnoea hypopnoea index after supraglottoplasty irrespective of obstructive sleep apnoea severity, whereas patients who received non-surgical treatment had more variable and unpredictable results. Direct comparison of the change between the two groups did not find supraglottoplasty to be superior to non-surgical treatment. Larger prospective studies are recommended.
