Structural grafting in rhinoplasty

Many surgeons consider cosmetic rhinoplasty to be one of the most challenging facial plastic surgical procedures. Open-structure rhinoplasty allows for visualization of bony-cartilaginous deformities, preservation of nasal structural integrity, and precise nasal reshaping. The ultimate, external appearance of the nose is the sum of the interaction of the bony-cartilaginous skeleton and the skin soft-tissue envelope. This article describes the use of autologous, structural cartilage grafts in primary and secondary rhinoplasty. Emphasis is placed on the use of septal, auricular, and costal cartilage grafts to provide for a structurally sound skeletal framework and thereby a predictable postoperative result. Deformities of the middle and lower third of the nose are specifically addressed.

The upper buccal sulcus approach, an alternative for post-trauma rhinoplasty.

We suggest that it is possible to correct the stigmata of the post-traumatic nasal deformity by means of an upper buccal sulcus approach alone. This approach is demonstrated in a series of ten cadaveric subjects for the correction of nasal skeletal deviation or bossing. Furthermore, the technique, which avoids internal nasal scarring and violation of the internal nasal valve, has been successfully employed in four patients with a minimum of 9 months follow-up. We suggest that it is possible to conserve the internal nasal valve and avoid problems of nasal tip retractions using this approach in selected cases.     

Combined use of triple cartilage grafts in secondary rhinoplasty.

Secondary rhinoplasty on a patient with a middle vault deformity is one of the most challenging procedures for a plastic surgeon. In order to achieve proper nasal aesthetics and airway function, a surgeon most commonly chooses to engraft the nose with a spreader, dorsal onlay, or columellar graft. This paper examines the aforementioned techniques in the management of 25 patients who presented with a severe middle nasal vault deformity. METHODS: During the last 5 years, 25 patients received secondary rhinoplasty using triple cartilage grafts to repair severe middle vault deformities. Patients were then questioned at least 3 months postoperatively about both airway problems and cosmetic satisfaction. RESULTS: All the 25 patients indicated cosmetic satisfaction with 23 of the patients also achieving complete nasal airway function. Only two patients persisted to have an insufficient nasal airway. An endonasal examination revealed a slight nasal synechiae in one patient, while no anatomic problem was identified in the second patient. From a cosmetic standpoint, a straight dorsum with improved dorsal aesthetic lines and nasal profile, along with nasal-facial balance were achieved. When indicated, secondary rhinoplasty to repair a middle vault deformity using the combination of spreader, dorsal onlay, and columellar grafts to augment the nose has shown to have both functional and cosmetic benefits.

Pure fat grafting for breast reconstruction: An alternative autologous breast reconstruction

Plastic surgeons offer various options for breast reconstruction based on patient preference, underlying disease, and comorbidities. An alternative form of breast reconstruction exists, which includes tissue expansion with tissue expander and subsequent fat grafting without the use of implant or flap. We retrospectively reviewed the breast cancer patients who underwent breast reconstruction at our institution to identify those with pure fat grafting. Demographic information, complications, operative details, and BREAST‐Q scores were abstracted. From 2010‐2015, 10 patients were identified. Patients with unilateral or bilateral mastectomy followed by pure fat grafting had a median of 3.5 or 4 sessions and a total median fat grafting volume of 380 or 974.5 cc, respectively. Patients were followed for 12 months, and no complications or breast cancer recurrences were noted. Finally, BREAST‐Q scores at the 12‐month follow‐up were comparable to the preoperative values.     

An anatomic basis for revision rhinoplasty

As the popularity of rhinoplasty has increased, so have the expectations of both patients and surgeons alike. Revision rhinoplasty has become an evolving field with unique challenges. One must first address the patient's specific concerns and emotional issues. To properly repair the inadequacies of a failed rhinoplasty, the surgeon must thoroughly analyze and understand the anatomic causes leading to why the patient needs revision surgery.     

An atraumatic technique for harvesting cancellous bone for secondary alveolar bone grafting in cleft palate

Secondary alveolar bone grafting in cleft palate patients has been popularised by the Oslo group. Harvesting of the bone graft has been carried out by techniques developed initially for cranio-facial surgery. This paper describes a more refined technique applicable to the requirements of alveolar bone grafting. The Craig bone biopsy set is used to trephine cores of autogenous particulate marrow and cancellous bone from the iliac bone. The method was tested in a cadaver and then applied in 10 clinical cases. The aesthetic and functional results of this technique proved to be superior to the conventional approach.     

Tragal cartilage grafts in rhinoplasty: a viable alternative in the graft-depleted patient.

OBJECTIVE: To describe a simple technique for harvesting tragal cartilage and describe its use in rhinoplasty. STUDY DESIGN: Retrospective review. SUBJECTS AND METHODS: Rhinoplasties performed between January 2005 and June 2007 in which tragal cartilage grafts were utilized by the senior author (CSC) were reviewed to assess type of graft, preservation of tragal contour, and donor-site morbidity. RESULTS: Tragal cartilage grafts were used in three primary and three secondary rhinoplasty patients. Postoperative follow-up ranged from six months to 12 months. Tragal cartilage was used as five alar contour grafts, one lateral crural onlay graft, one dorsal onlay graft, and one infratip lobule graft. Tragal cartilage was used to close the septal perforation of one patient. Tragal contour was preserved in all patients, and there were no complications noted with this procedure. CONCLUSION: The tragus provides a simple, convenient alternative source of cartilage for rhinoplasty in graft-depleted patients.     

An evaluation of suture materials used in tendon surgery

The following suture materials have been evaluated for their suitability for use in flexor tendon repairs: 4/0 gauge monofilament and multifilament stainless steel, mono-filament nylon, monofilament polypropylene, monofilament polybutestor, braided polyester, braided polyglycolic acid and a monofilament polyglyconate. These were investigated for their tensile strength (both knotted and unknotted), their extension to failure and knot-holding properties. Stainless steel and monofilament polyglyconate appeared to be the most suitable in that they had high tensile strengths, both knotted and unknotted, and had good knot-holding security. The only disadvantages are that stainless steel is difficult to use and monofilament polyglyconate is absorbable. Polypropylene and braided polyester, although having lower tensile strengths, are reasonable alternatives.     

Off-pump coronary artery bypass grafting via partial sternotomy. An alternative to left anterior small thoracotomy.

Four patients, who were considered to be inappropriate candidates for left anterior small thoracotomy, underwent off-pump coronary artery bypass grafting via partial sternotomy. Under a median skin incision over the lower half of the sternum, the sternum below the second rib was cut in an "inverted L" (or "C") shape. Without cardiopulmonary bypass, the left internal thoracic artery was anastomosed to the left anterior descending artery in all patients, and a saphenous vein graft was anastomosed to the right coronary artery in one of them. Partial sternotomy has some advantages as an alternative to left anterior small thoracotomy, in that it enables multiple-bypass grafting without cardiopulmonary bypass and conversion to cardiopulmonary bypass, should it be come necessary, would be relatively uncomplicated.
