Determinants of facial profile self-perception
American Journal of Orthodontics
|September 1, 1980
Summary
Orthodontic patients and controls underestimated their lip protrusion, impacting self-perception. This finding suggests a need for better profile simulation tools in orthodontics and surgery to assess patient expectations.
Area of Science:
- Orthodontics
- Psychology
- Medical Imaging
Background:
- Self-perception of facial features, particularly lip protrusion, is crucial in orthodontic treatment planning.
- Previous research indicates a general tendency for individuals to misjudge their own physical appearance.
Purpose of the Study:
- To compare perceived vs. actual lip protrusion in orthodontic and non-orthodontic patients.
- To investigate the psychological impact of perceived lip protrusion on patient anxiety and satisfaction.
- To evaluate the utility of a simple profile-simulation device for assessing patient expectations.
Main Methods:
- A profile-simulation device was used with 42 orthodontic and 42 non-orthodontic patients.
- Participants indicated their current and desired facial profiles.
- Actual profiles were determined cephalometrically for comparison.
- Psychological measures assessed anxiety and profile dissatisfaction.
Main Results:
- Both patient groups underestimated the degree of their lip protrusion.
- A significant correlation was found between the magnitude of actual and perceived lip protrusion and levels of anxiety and profile dissatisfaction.
- The simulation device provided a means to compare perceived and actual profiles.
Conclusions:
- Patients often have inaccurate perceptions of their lip protrusion, affecting their psychological well-being.
- Improved profile-simulation techniques are needed for orthodontists and surgeons to accurately gauge patient needs and expectations for corrective procedures.
