Some possibilities are shown to cover defects in the ear region. Especially "bi-loped flaps" will be used, and some variations of this type of flap are described.
We have developed several variations of the "bilobed flap" for the reconstruction of large defects of the head and neck. In so doing, we use pedicled bi- and tri-lobed flaps, transposition-rotation skin flaps or double-rotation skin flaps. Some examples are described to illustrate the technique employed.

A case of a rare, large pedunculated esophageal fibrolipoma is reported. Early symptoms involved regurgitations into the oral cavity. Correction was accomplished by endoscopic removal of the growth.
Butyl-2-Cyanoacrylate-glues are a valuable addition to the usual suture materials. Uner strict observance of the instructions (Contzen 1968) and application of small amounts which must not enter the wound, these glues can be successfully used in combination with suture material for the adaptation of flaps, the closure of stitch canals or for securing of suture lines. The successful use in surgery of the lung and trachea confirms our results (v. Windheim 1968, 1969, Häring 1968, Heiss 1968).
On 34 rabbits we supported the trachea with endotracheal tubes of PVC or PTFE (Teflon). Results are discussed. To obtain satisfying results, it is necessary to use short, soft and inert tubes without sharp edges at the ends. The prostheses should be fixed in the trachea. Immobilisation of head and neck with a plaster-collar minimizes mechanical irritation.
