Transcoronal blepharoplasty.

Some of the patients requesting blepharoplasty have a combination of excessive eyelid fat and brow ptosis but little or no dermatochalasis. Coronal brow lift, combined with transcoronal fat removal, serves these patients well. The prelevator fat pocket is easily entered from above by incising the periosteum of the anterior orbital roof just inside the orbital rim. Since the orbital septum and anterior lamella of the eyelid rim remain undisturbed, the result appears natural. Contraindications to the procedure include significant medical pocket fat and hair patterns that would exclude a coronal or hairline incision. Two complications, unilateral ptosis and unilateral chemosis, were temporary and totally reversible. Minor changes in the procedure have prevented the recurrence of these problems.

Hypersensitivity dermatitis following suction-assisted lipectomy: a complication of local anesthetic.

We report a case of severe dermatitis involving the abdomen and thighs following suction-assisted lipectomy of these areas wherein local anesthetic containing the preservative methylparaben was used for infiltrative anesthesia. This use of local anesthetics with epinephrine can be of value in the performance of suction-assisted lipectomy to reduce blood loss, serve as an adjunct to other intraoperative anesthetic techniques, and for postoperative analgesia. Local anesthetic solutions commonly contain additives, which serve as antioxidants and antimicrobials. The most common of these preservatives is methylparaben, which can cause delayed hypersensitivity reactions. These reactions may be neither recognized nor clinically significant in small areas of infection, whereas in large body surface infiltrative procedures, such as suction-assisted lipectomy, these reactions may be of considerable consequence. This article reviews the pathophysiology and treatment of these reactions and gives recommendations for avoiding them.

Surgical correction of lesions of the temporomandibular joints.

The previous report of 140 cases of TM joint disorders from the University of Michigan experience has been updated by the addition of 25 recent cases of surgical management of TM joint pathology. The surgical correction pathology of the articular disc, the condyle head, the articular eminence of the glenoid fossa, ankylosis, and chronic dislocation is discussed. Our experiences in these 25 cases are summarized.
