Title

RELATIONSHIP BETWEEN OROPHARYNGEAL SPACES WITH CLASSLL DIV I MALOCCLUSION

Pages

  95-103

Abstract

 The role of pharyngeal space has been debated on developing respiratory problems and craniofacial deformities for many years. The purpose of this investigation was to find any differences in oropharyngeal dimensions between skeletal class I and class If MALOCCLUSIONs.Eighty patients with class I MALOCCLUSION (40 in 9-13 year & 40 in 18-30 year-old age groups) were compared to sixty patients with class Il MALOCCLUSION due to mandibular deficiency (30 in 9-13 year & 30 in 18-30 year old age groups). Patients were selected from those who had no respiratory problems, facial asymmetry, aberrant growth pattern, parafunctional habits, TMJ diseases, vestibule-cochlear, visual & hearing disorders, hypertrophy of adenoids or tonsiles, previous orthodontic treatment or maxillofacial surgery.A lateral cephalogram in Natural Head Position was taken from every patient. Skeletal relationships of craniofacial structures and oropharyngeal dimensions were measured together with the soft palate. Hyoid bone and cervical column position Results indicated that:1- There was no difference in oropharyngeal dimensions, soft palate, hyoid hone and cervical vertehral column position between skeletal class I and class If MALOCCLUSIONs in the normal respiratory pattern.2- Oropharynx showed some degree of growth in vrtical dimension during the growth period whereas  its sagittal depth remained mostly stable, except in the upper and lower border al class I MALOCCLUSION (PNS-UPW: p<0.01, Spt-PSpt: P<0.03, Va-PVa: P<0.01).The hyoid bone showed down ward move while the posture of cervical column and facial growth had no change. Finally, Soft palate showed a significant increase in length (PNS-U: P<U.OI) at class I MALOCCLUSION.
