Final answer:
The correct surgical procedure for correcting external ear deformities or the pinna is otoplasty. Rhinoplasty, liposuction, and blepharoplasty are procedures for other parts of the body.
Step-by-step explanation:
The surgical procedure used to correct external ear deformities or the pinna is known as otoplasty. This procedure is designed to alter the shape or position of the ears, often performed to make the ears less prominent or to correct structural issues. The pinna, also referred to as the auricle, is the visible external part of the ear that protrudes from the head and is responsible for directing sound waves toward the auditory canal. It is important to distinguish otoplasty from other cosmetic procedures such as rhinoplasty which corrects the nose, liposuction which removes excess body fat, or blepharoplasty which is eyelid surgery. Otoplasty is the correct choice for addressing pinna deformities.
