The prominent nasal tip.

    Summary
    This summary is machine-generated.

    Alar cartilage hypertrophy causes nasal tip projection and bulbosity, unrelated to nasal index. Surgical correction involves excising cartilage segments to refine nasal shape.

    Area of Science:

    • Plastic Surgery
    • Otorhinolaryngology
    • Facial Anatomy

    Background:

    • Nasal tip projection is often linked to alar cartilage hypertrophy.
    • Bulbous noses may involve increased columellar-alar angle and excess fatty tissue.
    • Cephalometric nasal index is not correlated with these nasal tip characteristics.

    Purpose of the Study:

    • To investigate the anatomical basis of nasal tip projection and bulbosity.
    • To describe surgical techniques for correcting these nasal deformities.
    • To clarify the relationship between nasal tip morphology and the nasal index.

    Main Methods:

    • Analysis of alar cartilage morphology in relation to nasal tip projection.
    • Description of surgical excision techniques for medial branches of alar cartilages.

    Related Experiment Videos

  • Evaluation of the effect of surgery on the columellar-alar angle and nasal index.

    • Main Results:

    • Nasal tip projection is associated with hypertrophy of the medial branches of alar cartilages.
    • Bulbous nose morphology is linked to an increased columellar-alar angle and potential fatty tissue excess.
    • Surgical resection of alar cartilage segments effectively lowers the nasal tip and decreases the columellar-alar angle.
    • The cephalometric nasal index remains unaffected by these corrective procedures.

    Conclusions:

    • Alar cartilage hypertrophy is the primary cause of nasal tip projection.
    • Surgical correction of nasal tip projection and bulbosity can be achieved by specific alar cartilage resections.
    • Nasal index is not a determinant of nasal tip projection or bulbosity.
