Abstract

Introduction: Cephalometric analysis for Ortho-Gnathic Surgery (COGS) is the most commonly used analysis for diagnosing and treatment planning of an orthognathic case. This analysis consists of 37 parameters under 7 subheading which covers cranial, skeletal, dental, facial parameters. While performing this analysis it becomes very cumbersome for an oral surgeon and orthodontist to discuss the case with all the parameters in mind. So this study was done to determine the parameters of preference for an Oral surgeon and Orthodontist respectively.
Materials and Methods : 20 Oral surgeons and Orthodontist with 2 years of experience were selected for this study. The selection was done randomly by selecting the specialist through online list. A preferential form consisting of all the parameters of COGS analysis with three preference for each parameter-1): Important, 2): Slightly important and 3): Not so important, were distributed to both the specialists. The forms were collected and the data was tested statistically.
Results: Percentage wise preference was determined for various parameters. Majority of Oral and maxillofacial surgeons marked skeletal parameter as important while Orthodontist marked soft tissue as important. There was mutual agreement of preference in various parameters: Anterior cranial base (Ptm-N), Lower anterior face height (Ans-Gn), Upper posterior face height (PNS-N) which was statistically significant. Linear, angular, ratio measurement were preferred differently by oral surgeons and Orthodontists.
Conclusion: Skeletal measurements were preferred by oral surgeons followed by soft tissue & dental relationship, while as Orthodontists preferred Soft tissue, dental measurements followed by skeletal parameters.Cranial base measurements were not so marked as Ist preference by both the specialists.
