Correlation between cephalometric nasal changes and patients' perception after orthognathic surgery.

Area of Science:

• Dentistry
• Orthodontics
• Plastic Surgery

Background:

• Class III malocclusion often requires orthognathic surgery.
• Surgical correction can alter facial soft tissues, particularly the nose.
• Understanding patient perception of nasal changes is crucial for treatment outcomes.

Purpose of the Study:

• To correlate cephalometric measurements with patient perception of nasal changes after orthognathic surgery.
• To assess subjective and objective patient evaluations of nasal aesthetics.
• To investigate the impact of maxillary advancement with or without impaction on nasal form.

Main Methods:

• Eighty-five patients with Class III malocclusion undergoing maxillary advancement were included.
• Lateral cephalometric radiographs were analyzed pre- and post-treatment.
• Patients completed esthetic evaluation forms for subjective and objective nasal assessment.

Main Results:

• Significant changes in nasal tip inclination, rotation, nasofacial angle, and pronasale position were observed.
• Nasal tip protrusion and nasofrontal angle decreased significantly.
• Patients reported significantly higher objective nasal esthetic scores post-surgery.

Conclusions:

• Maxillary surgical movements influence soft tissue nasal changes.
• A moderate correlation exists between cephalometric measurements and patient-perceived nasal changes.
• Objective nasal esthetic scores improved significantly post-orthognathic surgery.
