Microscopic applied anatomy study of morphological structure of auricle / 中华显微外科杂志

ABSTRACT

Objective To provide structure and function applied anatomical of auricle stabilizing system for plastic and reconstruction.Methods Twelve cases fresh ears from adult head specimen,to dissect the skin,muscle fascia system and cartilage,to observe nerve,blood vessel and structure of cartilage.Results The structure of auricle Including the perichondrium,auricle cartilage,muscle and ligament.There was a rich blood supply for auricle stabilize system.The mainly blood supply come from posterior auricular artery diameter was 1.2 ± 0.2 cm and superficial temporal artery diameter was 2.6 ± 0.3 mm.Vein accompanying with the same name.Lymphatic flow in the area of superficial muscle fascia.Conclusion The blood supply of posterior auricular artery and superficial temporal artery play a crucial role in auricle repair and reconstruction.The main structure of stable system was elastic cartilage.Auricle cartilage and muscle play an important role in the microsurgery of auricle cartilage morphology and location.
