Augmentation rhinoplasty with dermal graft and review of the literature

Nasal augmentation required following a trauma or a rhinoplasty operation poses a challenging problem to many plastic surgeons. Currently, allografts and autologous tissues are used for nasal augmentation; however, an ideal technique has not yet been described. Although preferred for augmentation of different parts of the body, pure dermal graft use has not been described for nasal augmentation. The authors performed nasal augmentation using a dermal graft in 90 patients in their hospital between 1994 and 2000, and they followed up the patients for 6 months to 8 years. In this article, the early and late results of dermal grafts for nasal augmentation are presented, and their advantages and disadvantages are discussed with a review of the literature. It was concluded that the easily obtained dermal graft could be an appropriate alternative in nasal augmentation, though it has not been used widely for this purpose.

Augmentation mammaplasty: retrospective analysis of 210 cases.

Since its introduction in 1895, augmentation mammaplasty has gained widespread acceptance. The choice of breast augmentation procedure is determined almost entirely by three variables: the selection of incision location, the pocket plane for implant placement (either subpectoral or completely subglandular), and the appropriate implant. The current study evaluated 210 cases of augmentation mammaplasty retrospectively. A capsular contracture rate of 8% was found. Rupture and gel bleeding were observed in eight cases (4%). For various reasons, such as capsular contracture or implant rupture, the prostheses were renewed once in 16 patients (8%) and twice in 5 patients (2%). Submammary incision was used in 42 cases (20%). The patients in 23 cases responded that they had implant folds or edges they could feel (11%). Only 4 of these 23 patients stated that feeling the edge of the implant was a concern for them. Of the 210 augmented breasts, 5 had diminished sensation postoperatively (2%), as interpreted by the patient.

Application of external fixators in major foot contractures

Extremity contractures are one of the most common deformities faced by the reconstructive surgeon. Major deformities with ankylosis of the related joint have to be managed by both soft tissue and bone operations. Contractures existing for a long period of time cannot be brought into anatomic position easily because of shortened tendons, nerves, and vessels or ankylosed joints. Although tendons can be lengthened in one operation, this is not the case for neural and vascular structures. The authors use external fixators associated with soft tissue procedures to gradually correct major foot dorsiflexion contractures.

Prospective comparative study of the range of movement of temporomandibular joints after mandibular fractures: rigid or non-rigid fixation.

Temporomandibular joints (TMJ) are negatively affected by trauma and disuse. In this prospective study, 103 patients with mandibular fractures were evaluated for the influence of trauma and maxillomandibular fixation on the TMJ. A total of 54 patients were treated by maxillomandibular fixation and 49 by titanium miniplate fixation. Those patients with condylar fractures and multiple mandibular fractures and malocclusion at presentation were not included in the study. The control group consisted of 44 randomly-selected healthy people with no past history of mandibular fracture or symptoms referable to the TMJ. Trauma was a major factor leading to TMJ dysfunction and maxillomandibular fixation increased the incidence and severity of TMJ dysfunction.

Umbrella graft of columella tip: 20 years' experience.

Abstract. We present our experience with nasal grafts over 20 years. The nose, located centrally, always plays a key role in facial aesthetics. Public recognition of this makes rhinoplasty the most popular operation. From the traditional aesthetic point of view, propogated by the media, the nose must be narrow and straight and have correct nasolabial and forehead angles. It is the desire of every surgeon to obtain permanent and satisfactory cosmetic results. However, it is not always possible to obtain good cosmetic appearance using conventional methods when the nose is small or large, when the columella is short, or when the skin is thick. Mostly, nasal tip projection cannot be achieved. In the present article, we report our experiences in primary asthetic rhinoplasty using cartilaginous grafts obtained from septum, costa, and ear as umbrella grafts of columella type.

Open Rhinoplasty Without Transcolumellar Incision

Traditional open rhinoplasty leaves a scar on the columella. No one can say that this scar is invisible. It is less noticeable in Caucasian patients but it is a problem in non-Caucasian patients like in our country. To avoid such a scar and still obtain a wide exposure of the nasal framework, the bilateral paramarginal incisions close to the columella were extended down to the nasal floors. The lower lateral cartilages forming the nasal tip could then be delivered out through one of the nostrils. An exposure similar to the traditional open rhinoplasty was then achieved. The technique has been used in 23 patients with satisfactory results. In conclusion, the open rhinoplasty without transcolumellar incision can replace the traditional transcolumellar open rhinoplasty technique in selected patients.

A Useful Method for Planning Hump Resection of Deviated Nose

The deviated nose is a particular challenge because both functional and aesthetic problems must be addressed. A most important challenge is resection of the hump. The nasal bones often are asymmetric in deviated noses. Several methods have been used for resection of the hump. Using the authors’ method, it is possible to calculate the extent of hump resection. Clinical analysis of the nasal deviation is performed preoperatively. Digital photographs are taken, and all the landmarks are marked on the life-size photo prints. Planning begins on the deviated side. The ideal dorsal line is drawn, and the extent of hump resection is planned according to the preoperative measurements. Measurements on the deviated side are applied to the other side using the medial canthi and the most prominent part of the alar creases as landmarks. Classical methods emphasize the importance of the chisel position during hump removal. According to the classical approach, the chisel should be positioned lower on the deviated side to resect more bone. However, there is no method for calculating how the chisel should be positioned exactly during hump resection. Therefore, a precise plan has been devised to leave symmetric nasal bones after hump resection. The authors have applied this method in eight cases, achieving satisfactory results.

The Fate of Folded and Unfolded Dermal Grafts: A Histopathologic and Structural Study of Rabbits

Currently, both autogenous and nonautogenous materials are used to treat contour deformities. Autogenous grafts are preferable to nonautogenous grafts because they cause less reaction and are both inexpensive and easy to obtain. Currently, however, no consensus exists on an ideal autogenous graft. As autogenous materials, dermal grafts can be obtained from scar tissue, allowing simultaneous revision of scars, quicker vascularization than with other autogenous tissues, and a very short immobilization for their stabilization (i.e., they interact with surrounding tissues). The operation can be performed with the patient under local anesthesia, providing regular contours easily. Alternative techniques are needed to increase the viability and mass effects of autogenous grafts in the long term. With this as the objective, folded dermal grafts were used to increase the mass effects of dermal grafts. The current study compared long-term histopathologic and structural changes in unfolded and folded dermal autogenous grafts used for correction of soft tissue contour deformities. Thicknesses and histopathologic changes of the unfolded and folded dermal autogenous grafts were evaluated 6 and 12 months after placement of the grafts in the abdomens of 10 rabbits. Both the authors’ observations and histopathologic examinations showed that the folded dermis caused a more severe granulomatous reaction and fibrosis. Graft thicknesses considerably increased in the first 6 months, but then almost leveled off in the following months. Increased fibrosis in the folded grafts had a masslike effect, which was preserved in the long term, suggesting that folded dermal grafts can be used clinically.

Isolated Unilateral Hypertrophy of the Plantar Muscle: A Case Report

An 18-year-old woman presented with a painless mass in the left plantar region that enlarged and caused asymmetry between her feet as she matured. The patient’s complaint was that she was wearing a shoe on her left foot that was two sizes larger than that on her right foot. However, she did not have any difficulty in walking, running, or movement of her feet. Physical examination revealed a painless soft mass located on the medioplantar surface of the left foot. The plantar arch of the foot was completely obliterated, and the foot appeared to have pes planus (Figure 1). The mass was harder and more marked when the toes were flexed, and the big toe was abducted. The left ankle and toe joints had full ranges of flexion, extension, eversion, and inversion. There was no popliteal or inguinal lymphadenopathy. Motor examination revealed 5/5 muscle strength in the left lower extremity. Sensory

Postauricular Cartilage Storage in Rhinoplasty

Abstract. In the past decade, the number of patients demanding rhinoplasty has increased, and this has increased the use of grafts. Although different materials are used as grafts, cartilage is the most popular one. In secondary rhinoplasties the need for cartilage is very frequent. The most suitable cartilage grafts are the ones extracted during primary rhinoplasty. These grafts are disposed of after the operation and in a secondary operation, grafts are obtained from a new donor site.In our department, the surplus cartilages obtained during primary rhinoplasties of the patients who are thought to be probable secondary rhinoplasty candidates are stored in a postauricular pocket after their volumes are measured and marked down. In the secondary operations the volume of the grafts are measured again and the grafts are used.We have found out that there is no significant difference between the initial and secondary volumes of lower lateral cartilages (3.6% of initial volume is lost), but the difference between the initial and secondary volumes of septal cartilages is significant (6.9% of initial volume is lost), and the stored cartilages are sufficient qualitatively and quantitatively for the secondary rhinoplasties.
