‘Comparison and correlation of the maxillary sinus dimensions in various craniofacial patterns: A CBCT Study’

Abstract

BACKGROUND To compare and correlate the maxillary sinus dimensions and basal bone height among various facial patterns using CBCT for advanced diagnosis and treatment planning in Orthodontics. METHODS 66 CBCT images within age group of 18-30 years were divided into horizontal (Group 1), average (Group 2) and vertical (Group 3) facial growth patterns. Maxillary sinus dimensions were compared and correlated in all three groups. The sinus height and basal bone height were recorded at 3 locations-between 1st premolar and 2nd premolar (PM1-PM2), between 2nd premolar and 1st Molar (PM2-M1) and between 1st and 2nd molar (M1-M2). RESULTS Overall reduction in sinus height and significantly reduced sinus volume was seen in Group-1. Longest maxillary sinus height in M1-M2 region and shortest in PM1-PM2 region was seen in Group-3. The basal bone height in PM1-PM2 region was significantly longer in Group-3 than in Group-1(p<.05).Shortest basal bone height in M1-M2 region was seen in Group-3. A significant negative correlation was seen between the maxillary sinus height and the basal bone height in Group-1 and Group-3(p<.05). CONCLUSION There is a correlation between the maxillary sinus height and basal bone height with that of facial pattern which needs to be considered during orthodontic treatment planning and while carrying out facial growth modification procedures in younger patients.

Cone Beam Computed Tomographic Evaluation of the Maxillary Sinus in Different Craniofacial Patterns

“…This is an anatomical limitation that may hinder the mobility of teeth during orthodontic treatment and lead to complications. Any change in the maxillary sinus' growth could consequently result in the development of skeletal or dental malocclusion [3] .…”

“…In contrast, Kumar et al compared and correlated the maxillary sinus dimensions and basal bone height among various facial patterns using CBCT images. They came to the conclusion that there is a relationship between the height of the basal bones and the maxillary sinuses with the facial pattern, which should be taken into account while planning orthodontic treatments and performing facial growth modification procedures on younger patients [3] . Moreover, Przystańska et al retrospective analysis of head CT scans revealed a correlation between midface dimensions and all measurements of the maxillary sinuses [7] .…”

“…Maxillary sinus plays a significant role in relation to the craniofacial structures as it is located in close proximity to the maxillary dentition and the adjacent structures, and it influences how the dentition and facial shape develop over time. Understanding the relationships between maxillary sinus dimensions and craniofacial patterns can provide valuable insights for orthodontic treatment planning, implant placement, and surgical procedures [3] .…”

“…Several previous studies have assessed the correlation between the maxillary sinus and one or all types of craniofacial growth with contrasting results [3][4][5][6][7] . So, the aim of the present study was to find if there is a correlation between maxillary sinus dimensions and different craniofacial patterns using 3D-CBCT.…”
