Block and Surgicel-wrapped diced solvent-preserved costal cartilage homograft application for nasal augmentation.

BACKGROUND: Cartilage grafting has been used extensively to correct the nasal framework in traumatic and postrhinoplasty nasal deformities. Autologous cartilage grafts yield satisfactory reconstructive results, but their use is limited by donor-site morbidity, patient choice, the requirement for increased operative time, and the lack of a sufficient quantity and availability of tissue for more extensive deformities. Alternatively, preserved costal cartilage homograft represents a readily available, easily contoured material. METHODS: The preserved costal cartilage homograft has been used by the authors on 68 patients over the past 5 years: in 52 patients with postrhinoplasty deformity and in 16 patients with traumatic nasal deformity. In cases with more severe nasal depression, the cartilage graft was carved and placed over the remaining septum in block form. The "Turkish Delight" technique, which was initially described by Erol, was used in cases of mild to moderate nasal depression. The cartilage graft was diced into 0.5- to 1-mm pieces. The diced cartilage mass was then wrapped in Surgicel and inserted under the dorsal nasal skin. RESULTS: Follow-up ranged from 6 months to 5 years. During this period, no major complications were noted, and satisfactory results were obtained. Recurrence of the dorsal depression was seen in five patients and required repeated augmentation. The complication and revision rates were acceptable. CONCLUSIONS: This technique seems to be effective for augmentation of the nose, shortens the operative time significantly by eliminating graft harvest, and avoids donor-site morbidity. Therefore, it is recommended for nasal augmentation and contouring for traumatic and postrhinoplasty nasal deformities.

Augmentation mentoplasty using a custom-design wire cage.

Mentoplasty is often a complimentary procedure to rhinoplasty. At least 25% of all rhinoplasty patients may need a chin implant to balance facial features better. Augmentation mentoplasty using alloplastic implants such as silicone, rubber, or other materials provides a simple approach to the treatment of the hypoplastic chin. Although these types of implants are readily available in developed countries, there are parts of the world where they are unavailable or quite expensive. The authors have developed a chin implant made of wire that is available throughout the world and is custom designed to the mentum of the patient after a cephalometric evaluation. This technique has been used in 125 patients along with rhinoplasty over the last 20 years at our institution. In an initial series of 8 patients, the prosthesis became displaced and was removed in 2 patients. Since then, a new radiographic technique has been developed to demonstrate the shape of the mentum before surgery and new bone formation after surgery. By using this special radiographic technique, it was possible to detect four types of mentum before surgery and to construct a custom-design wire cage according to this shape. The prosthesis is constructed by an orthodontist according to the cephalometric measurements and shape of the mentum. By using the buccal approach, a pocket is prepared subperiosteally and a wire cage is inserted. In the last 20 cases, the wire cage was filled with diced cartilage wrapped with Surgicel. The results were esthetically satisfactory in most patients. After the shape of the wire prosthesis was modified to conform to the shape of the underlying bone better, no displacement of the prosthesis has been experienced. In 3 patients, it was necessary to remove the prosthesis when new tissue formation began to fill the prosthesis. These specimens were examined histologically, and the regenerating tissue was found to be connective tissue with a thin layer of bone formation. Most patients could be followed up for only 3 to 12 years. In all patients, the results have been consistent and the procedure has been safe.

Brow suspension, a minimally invasive technique in facial rejuvenation.

People tend to prefer noninvasive or minimally invasive methods of facial rejuvenation, especially when it involves their face, which is the hallmark of a person's identity and impossible to hide. It is widely known that brow ptosis gives the face a "tired look" and also accentuates deformities of the upper eyelid. Most people who are interested in facial rejuvenation may not accept even a minor surgery, such as an endoscopic surgery. The senior author has developed a minimally invasive method of suspending the brow at a higher position. In this technique, there is neither surgical dissection nor a surgical incision except for four stab incisions and suture insertion, which is why we refer to it as a nonsurgical brow suspension. It is done under local anesthesia, and the brows are fixed in the position that they assume when the patient is supine. In the past 6 years, we performed 387 brow suspensions on 324 female and 63 male patients. The youngest patient was 19 years old, and the oldest was 74 years old. A retrospective chart review was done. These 387 cases were reviewed by comparison of preoperative and postoperative photographs. This approach was not only used for patients who were not interested in surgical rejuvenation but was also combined with lipofilling, laser resurfacing, and/or upper blepharoplasty. This technique is useful for correcting postsurgical brow asymmetry. We present this technique as an adjunct to the established techniques of facial rejuvenation. Despite the high patient acceptance and technical ease, it is not a replacement for the established techniques of facial rejuvenation.

The treatment of burn scar hypopigmentation and surface irregularity by dermabrasion and thin skin grafting.

Scar tissue and leukoderma-type discoloration of the skin due to deep burns are treated by dermabrasion and thin split-thickness skin-graft application. This method was applied to 18 patients on whom the treated lesion sites were located as follows: 8 in the facial area, 9 on the extremities, and 1 on the neck. Adequate repigmentation and flat surfaces were obtained in all patients at the end of 6 months, and results persist at the end of a considerable follow-up period (1 to 4 years). The technique, advantages, disadvantages, and results are discussed.
