Presternal bronchogenic cysts.

A presternal subcutaneous cyst was removed from a 21-month-old male infant. This is a rare congenital lesion that typically appears as a pinpoint opening over the sternum that periodically drains small amounts of mucinous material. Histologically, these lesions have the features of their intrathoracic and mediastinal counterparts. Surgical excision is advocated because of the potential for infection.

"Practical suggestions on facial plastic surgery--how i do it". Z-plasty repositioning of an anatomical unit.

The Z-Plasty was originally described in the writings of Hippocrates and since that time has developed into one of the most useful techniques in facial plastic surgery. Familiarity with its myriad of uses is invaluable to the practicing otolaryngologist. The basic technique of Z-Plasty consists in the design and transposition of adjacent triangular soft tissue flaps. Most common applications capitalize on the changes which occur during transposition to the common limb between the flaps. The resultant lengthening is used to provide needed tissue in areas of contracted scars and the change in direction is useful in camouflage of scars which cross skin tension lines. Additionally, displaced anatomical units such as the auricle, angle of the mouth or eyelid can be included in the flaps of the Z-Plasty to transpose them into a new anatomical position. Many congenital and acquired deformities can be corrected by this technique without loss of valuable tissue. The purpose of this paper is to illustrate the above principle utilizing two patients with congenitally displaced auricles.

Soft tissue trauma.

Prior to surgical repair of maxillofacial injuries, a surgeon should formulate an operative plan based upon a careful and complete pre-operative analysis. Obviously this may effect the timing of repair. However, it is more efficacious to delay surgery for up to 24 hours than to close lacerations over a lacerated facial nerve, a severed parotid duct, or other undiagnosed lesions. Repair should include meticulous cleansing and removal of all embedded foreign material if hypertrophy, scars, or tattooing is to be avoided; repair of underlying soft tissue damage, including mucosa, muscle, nerve, cartilage, and subcutaneous tissue; and meticulous closure of the lacerations in accordance with their anatomical location. In wounds involving tissue loss the judicious application of skin grafts, as well as local or regional flaps, is of infinite value. With the careful adherence to the basic principles of plastic reconstructive surgery, the majority of patients with maxillofacial injuries should obtain a good functional and esthetic restoration. In patients in whom this cannot be accomplished because of extensive tissue damage, the primary repair should enhance the feasibility and results of secondary reconstruction.

Medial conchal excision in otoplasty.

The most common cartilaginous deformities in protruding ears include an inadequate antihelical fold and an enlarged concha. We have employed medial conchal excision to correct deep conchas in 25 patients, all of whom were pleased with the postoperative result. Obvious wrinkling of the anterior skin occurred in four patients, and several patients displayed slight distortion of the helical crus. Medial conchal excision does not impede management of the antihelical fold with mattress sutures or by other means. We consider the risk of minor alterations of the concha justified if even slight distortion of the more conspicuous lateral auricle can be avoided.
