Abstract
Relevance. Ankyloglossia (ICD-10: Q38.1) is a malformation of the lingual frenulum and its attachment, characterized by shortening of its mobile portion and leading to dentoalveolar anomalies. The lack of objective diagnostic methods complicates treatment planning and increases the risk of complications. Available statistics and diagnostic criteria have been derived almost exclusively from pediatric studies, whereas prevalence and clinical significance in young adults remain poorly understood.
Objective. To improve the effectiveness of ankyloglossia diagnosis in young adults using transoral ultrasonography.
Materials and methods. Ninety-five patients aged 23–29 years, divided into two groups – those with a normal lingual frenulum (Group I, n = 43) and those with a short lingual frenulum (Group II, n = 52 – were examined. A transoral ultrasonographic method was developed to assess the length and width of the lingual frenulum using a high-frequency 24-MHz L6–24 linear transducer (LOGIQ E10, GE Healthcare).
Results. On B-mode echograms, Group I participants without ankyloglossia had a lingual frenulum length of 2.5 ± 0.3 cm and a width of 0.20 ± 0.06 cm. In Group II with a short frenulum, length was 0.7 ± 0.2 cm and width 0.30 ± 0.08 cm. In 53.8% of Group II, B-mode cine loops acquired during swallowing demonstrated simultaneous contraction of the m. genioglossus and m. geniohyoideus on the monitor.
Conclusion. A high prevalence of ankyloglossia (54.7%) was identified among young adults, associated with mandibular incisor crowding in 32.7% of orthodontically untreated individuals. Transoral ultrasonography provides objective confirmation of functional impairment by visualizing abnormal attachment of the lingual frenulum to the floor-of-mouth muscles.
