Angular Relationship Between Frankfort Horizontal Plane And Sella-Nasion Plane In Bhavnagar Population: A Retrospective Cephalometric Study

Angular Relationship Between Frankfort Horizontal Plane And Sella-Nasion Plane

Abstract

Background: The angle between Frankfort horizontal (FH) plane and Sella-Nasion (SN) plane is considered to be 7°. Various studies have shown that the FH-SN angulations can vary; which can affect cephalometric diagnosis of a case. Objective: To determine the angular relationship between Frankfort Horizontal Plane and Sella-Nasion Plane in Bhavnagar population and to assess whether the FH-SN angle exhibits sexual dimorphism or not.Material And Methods: 85 Lateral cephalograms of patients belonging to Bhavnagar were retrieved from record room of department of orthodontics and dentofacial orthopaedics, college of Dental Science and Hospital, Amargadh. These were hand traced and angle between FH plane and SN plane was measured and recorded. Result: The average FH-SN angle was 7.19° ± 3.16°.FH-SN angle was greater in female samples compared to males. However, the difference was not statistically significant. Conclusion: The average FH-SN angle for a group of patients belonging to Bhavnagar was found to be 7.19° ± 3.16° which compared to the given norm.
