Perbedaan Posisi Tulang Hyoid Pasien dengan Kebiasaan Mouth Breathing dan Nasal Breathing

Abstract

The hyoid bone's mobility and adaptability contribute to its variable position, which is diagnostically significant in identifying mouth breathing. Changes in the position of the hyoid bone can serve as an important diagnostic guide in identifying mouth breathing. This study aimed to assess differences in hyoid bone position between mouth and nasal breathers aged 9-13 using lateral cephalograms. A descriptive analytical approach was employed, examining 60 patient samples from the Orthodontic Clinic at RSGM USU. Hyoid bone position was determined via the Bibby & Preston hyoid triangle method, with statistical analysis conducted using the independent samples ttest. Results indicated mouth breathers had larger mean values for C3-RGn (62.88 ± 9.23) and C3-H (37.45 ± 4.50), suggesting a more posterior and inferior hyoid bone position. Similarly, mouth breathers showed higher mean values for H-RGn (37.53 ± 6.11) and H-H' (11.18 ± 3.49), indicating significant anteroposterior and vertical differences compared to nasal breathers. Notably, while significant differences were observed in C3-H and H-RGn, C3-RGn values didn't differ significantly between the two groups. However, significant disparities were found in H-H' values, emphasizing the vertical distinction between mouth and nasal breathers. In conclusion, mouth breathers exhibit a more posterior and inferior hyoid bone position compared to nasal breathers, underscoring the impact of breathing habits on hyoid bone orientation.
