“…4,5,6 Airway analysis often included cephalograms, 7 and their reliability was found to be adequate. 8 Studies have shown an association between craniofacial morphology and airway dimensions, 9,10 and there is limited knowledge due to the effect of a steep mandibular plane angle on airway size. 11,12,13 Reduction in airway space after mandibular setback surgery in Class III patients was declared to be a causative factor in airway obstruction.…”

The aim of this study was to investigate the effects of reverse headgear (RH) on pharyngeal airway morphology in two groups of Class III patients with different vertical craniofacial features in comparison with an untreated Class III group. Seventeen subjects (9 males, 8 females; mean age 11.3 ± 0.98 years) with optimum vertical growth and 17 subjects (10 males, 7 females, mean age 11.5 ± 1.1 years) with a vertical growth pattern treated with a removable intra-oral appliance and a Delaire type facemask were included. An untreated Class III control group of 11 subjects (8 males, 3 females, mean age 9.1 ± 1.1 years) was included to compare the treated groups. The paired t-test for intragroup and one-way ANOVA for intergroup comparisons were performed. The relationships between changes in the craniofacial morphology and airway were assessed by Spearman correlation analysis. The airway dimensions at the adenoid side and soft palate were increased in the treatment groups compared to the control group (p < 0.05). The nasopharyngeal area demonstrated a significant difference in normodivergent and control subjects (p < 0.05). No significant difference was found in the airway morphology due to different vertical features. The effect of RH treatment on the sagittal airway dimensions revealed no significant difference between different vertical craniofacial features in the short term.

“…Compared with the normal values according to McNamara, 97.6% of our patients with OSA had reduced sagittal dimensions at the soft palate level, whereas 75.6% -at the tongue base level [18]. The reduced values of the sagittal dimensions of the upper airways were reported by many authors [3,[22][23][24][25]30]. Only Abu Allhaija et al [1] did not find a correlation between the changes in the ANB angle dimensions and anterior-posterior dimensions of the upper airway.…”

“…3 In our study according to palatine height index, 72.3% skulls had low (chamestaphyline), 26.1% skulls had intermediate (orthostaphyline) and 1.6% had deep (hypistaphyline) palates. On a study on Kenyan African skulls by Hassanali showed showed majority of orthostphyline (57%) followed by chamestaphyline (40%) and hypistaphyline.…”

INTRODUCTIONThe palate forms the roof of the mouth and floor of nasal cavities. It is divisible into two regions namely the hard palate in front and soft palate behind. The hard palate is formed by the palatine process of the maxilla and the horizontal plates of palatine bones united by cruciform sutures. 1The knowledge of morphology of hard palate is important as it plays a major role in the passive articulation of speech.2 Restricted development of hard palate is one of the cause for a condition known as sleep apnoea syndrome which is characterized by difficulty in breathing while sleeping. 3Procedures such as nasopharyngoscopy and nasogastric intubation will need a precise knowledge of normal structure and dimensions of these regions for meticulous manipulation and better designing of instruments. 4 Hence the present study was performed to determine the palatine length, breadth, height, and palatine index and palatine height index. These data will be useful to surgeons, clinicians, anatomists and anthropologists. METHODS65 adult skulls of unknown sex were procured from the department of anatomy, MVJMC & RH. With the help of ABSTRACT Background: The hard palate is an essential part of human skull, the detailed knowledge of which plays an important role in the passive articulation of speech. Methods: The present study was conducted on 65 dry skulls from the department of anatomy, MVJMC & RH, Bangalore. With vernier caliper, palatine length, palatine breadth and heights were measured. Palatine index and palatine height index were calculated. Results: Mean palatine length was 48.47 ± 4.66 mm. Mean palatine breadth was 36 ± 4.41 mm and height was 8.62 ± 2.76 mm. According to the palatine index range, 66% of the hard palate belongs to leptostaphyline, 18.5% belongs to mesostaphyline and 15. 5% was brachystaphyline. As per palatine height index, 72.3% of hard palate showed chamestaphyline followed by 26.1% orthostaphyline and 1.6% hypistaphyline. Conclusions: These observations can be utilised for ethnic and racial classification of crania, anthropological studies, fabricating complete maxillary dentures for edentulous patients and performing certain surgical procedures in hard palate & soft palate.
