ABSTRACT
OBJECTIVE: To evaluate the extraoral volume, intraoral volume, and tongue posture in pre- and post-LF1 and B.S.S.O maxillomandibular surgery for skeletal Class III patients, and establish a correlation between them.
METHOD: A retrospective study that evaluated 8 pre- and post-maxillomandibular surgical CT records of patients fulfilling the inclusion criteria. Borders were demarcated for volumetric measurement. The volume assessment was carried out using Materialise Mimics version 12.0 software.
RESULTS: The mean difference in intraoral volume was 8476 ± 6099 mm3, which was statistically highly significant. The mean difference in extraoral volume was 15005 ± 13704 mm3, which was statistically significant. The mean difference in tongue posture was 2.31 ± 0.63 mm3, which was statistically very highly significant. A strong positive correlation is between the mean differences in tongue-to-palate distance and intraoral volume. A weak negative correlation is between the mean differences in extraoral and intraoral volume and pre- and post-operative maxillomandibular surgery.
CONCLUSION: There was a significant decrease in the extraoral, intraoral volume, and tongue-to-palate distance following maxillomandibular surgery in skeletal Class III patients.
