1 The perichondrium carries the blood supply to the cartilage.

2 Methods Myringoplasties with autologous tragal perichondrium or allografts fascia by otoendoscopy was applied 63 cases.

3 The perichondrium of the cartilage is only partially contiguous with the periosteum of the crests.

4 Methods: The thyroid perichondrium with muscular pedicle was used. in 2 cases undergoing resection of laryngopharyngeal cancer during different patterns of repair operation.

5 Objective: To validate thyroid perichondrium with muscular pedicle in laryngopharyngeal repair.

6 The tracheal perichondrium was the originating site of adaptive cartilage regeneration.

7 Results As the graft materials in tympanoplasty, tragus perichondrium and temporal muscular fasciae are effective to enhance the efficiency of drum membrane and audile of patients.

8 Conclusion The newly formed fibrocartilage and the involved perichondrium must be totally removed to achieve the good results.

9 Reconstruction: Larynx: the remains of epiglottis, perichondrium of thyroid cartilage, the infrahyoid muscular fascia, and the platysmal flap were utilized to restore the defects of larynx.

10 Conclusion The incidence of aeropleura can be reduced by the methods. It is related between thoracic deformity and perichondrium left and refilled of the costal cartilages.

11 Results:There are five soft tissue components above the bone of nose:a skin, a superficial fatty layer, a deep fatty layer(loose tissue layer), a periosteum and perichondrium layer.

12 Dissection in the deep areolar plane will not ensure preservation of the lateral nasal veins that pass over the perichondrium of the middle nasal vault.

13 Objective To evaluate the outcome of arthroplasty with transplantation of autogenous rib perichondrium for reconstruction of the metacarpophalangeal joint.

14 Objective To investigate curative effect of the tragus cartilage ring with perichondrium for repairing tympanic membrane perforation.

15 Other fibers pass through the articulation to join the contralateral perichondrium.

16 Objective Evaluation of the effect in myringoplasty using antilobium perichondrium graft.

17 Methods The unilateral vocal cord, laryngeal ventricle, partial anteroinferior portion of ventricular band and the homolateral inner perichondrium of the thyroid cartilage were excised.
