    Surgical views of the left TMJ. (A) Cartilaginous loose body in the posterior recess under arthroscope. (B) Incision in the anterior wall of external auditory meatus. (C) Arthroscopic procedure. (D) The loose body was caught with a hemostat. (E) The loose body was removed via the additional incision in the anterior wall of the external auditory meatus. (F) Size of the loose body. (G) Arthroscopic view after surgery.

  • Image Result
    Histological examination of the loose body showed it was composed of hyaline cartilage covered by fibrous connective tissue (hematoxylin–eosin staining; original magnification 100×).
