Development of an Algorithm to Determine Which Costal Cartilage to Harvest.

Rib graft is a common source of cartilage in rhinoplasty. Donor site choices for this resource were identified according to the authors who presented the introduction of this technique. However, the scientific basis of this valuable method lacks information, including the anatomical properties of costal cartilage. In this study, cartilage radioanatomy is examined and tested for if any estimators are present. A total of 148 thoracal CT scans of patients who applied to our facility were analyzed. Patients were divided per their sex and age of 35, and rib cartilage dimensions, including axial length between the sternal and costal ends of the cartilage (TotL), posteroanterior diameters at the sternal end (StDia), costal end (CosDia), the thickest part (MaxDia) as diametrical parameters and vertical height at the thickest part (h) were recorded. Length of the sternum (St), the axial length of the clavicle (ClavL), the distance of the sixth rib from the anterior axillary border (AntAx), and thorax circumferences at the level of both pectoralis major muscle origin (ThC) and nipples (BrC) were recorded. Statistical analyses were done for correlations. St, ClavL, ThC, and BrC were found to have the most correlated measurements in groups with the age of 35 and less of both genders, and the relations were lost in older groups. Thorax shape may change after the age of 35 years, but in younger patients, St in females and ClavL in males can be used as estimators of cartilage amount.

Replantation of Pediatric Scalp Avulsions.

Scalp avulsions are rare but can be quite morbid clinical manifestations. Pediatric patients are different from adults as they have not completed their physical, sexual, educational, or psychosocial development. Therefore, the devastation of a failed scalp replantation is much greater on these individuals, their whole future lives, and families. We present 2 consecutive pediatric cases retrospectively with the youngest successful replanted patient in Turkey and describe technical tips according to our experience.

Comparison of skin effects of immediate treatment modalities in experimentally induced hydrofluoric acid skin burns.

Hydrofluoric acid (HF) burns cause immediate damage and painful long-term sequellae. Traditionally, chelating agents have been used as the initial treatment for such burns. We have introduced epidermal growth factor (EGF) into an HF model to compare EGF with Ca(2+) and Mg(2+) treatments; 40 Sprague Dawley rats were divided into five groups. Each rat suffered a 6 × 4 cm(2) burn induced by 40% HF. Group 1 had no treatment, group 2 had saline injected beneath the burn, group 3 received magnesium sulphate injections, group 4 received calcium gluconate and group 5 received EGF. Specimens were evaluated via planimetry and biopsy at intervals of 4, 8, 24 and 72 hours. Fluid losses were significantly less in the Mg(2+) and EGF groups. The EGF group had the smallest burn area, least oedema, least polymorphonuclear granulocyte (PMN) infiltration, most angiogenesis and highest fibroblast proliferation of any group (P < 0·005). EGF limited HF damage morphologically and histologically more effectively than Ca(2+) or Mg(2+). This finding indicates that HF treatment via growth factors may be an improvement over chelation therapy.

Y-to-V setback for prominent lobule correction in otoplasty.

Prominent ears may be very distressing for the patient and they need to be corrected. The situation is especially important for school children or the teenagers as it may cause peer criticism and psychological issues. Various techniques have been suggested, and it is possible to obtain a successful result with one of these techniques chosen according to the patient's specific needs and the surgeon's preference. However, there are not many publications regarding the finer details of this operation such as the correction of the prominent lobule. There are few techniques available with limited success. In this study, we humbly present our Y-to-V setback technique for correction of the prominent lobule, as an individual operation or as an adjunct to a successful otoplasty. A total of 22 cases in which prominent lobule correction had to be performed during otoplasty were included in our study. Mean age of the patients was 21.3 years. Of the 22 patients, 14 were female and 8 were male. All cases underwent bilateral lobule transposition together with bilateral otoplasty. All cases have been followed up for at least 12 months. Mean follow-up was 20 months. The lobule incisions were inconspicuous, and they were well hidden in the postauricular sulcus. Hypertrophic scars or keloid were not seen in any cases. No relapse of lobule prominence was seen during the follow-up period. All patients were satisfied with their results. One of the reasons the ears may look unnatural or "operated" after an otoplasty is the disharmony of the lobule with the corrected parts. Even normal lobules may become relatively prominent after medialization of the helix. It is suggested that the use of a "v"-shaped advancement flap elevated from the posterior surface of the lobule may be a very useful technique to set the lobule back to the desired extent.

Protective effect of grape seed extract against ischaemia/reperfusion injury in a rat epigastricflap model.

Proanthocyanidins are potent natural antioxidants which belong to a class of polyphenols. Proanthocyanidin-rich extracts are prepared from grape seeds. The effect of grape seed proanthocyanidin extract (GSPE) on the viability of abdominal skin flaps exposed to warm ischaemia and subsequent reperfusion were studied in 40 male Wistar rats. In the control group (group I; n=20), rats were fed with standard, non-purified rat diet, and the study group received GSPE 100 mgkg(-1) per day 1 week prior to surgery and 1 week following surgery. Abdominal island flaps were elevated in both the groups and subjected to 8h of warm ischaemia, followed by reperfusion. Mean flap survival areas in groups I (control group) and II (treatment group) were calculated to be 58.3%+/-11.72 and 81.0%+/-11.88, respectively. Flap survival on day 7 was significantly higher in group II compared to group I (p<0.01). Histopathological semi-quantitative analysis of the specimens revealed infiltration by polymorphonuclear leucocytes, oedema formation and necrosis in group I, whereas neo-vascularisation and fibrosis were the prominent findings in group II.

What is new in the treatment of hypospadias?

Hypospadias is a congenital anomaly characterized by a ventrally placed urethral meatus in a more proximal position on the midline than its normal position in the glanular part of the penis. In 1961, C. E. Horton and C. J. Devine, Jr., developed single-stage modern surgical techniques, namely, local skin flaps and free skin grafts, for urethra reconstruction in hypospadias repair, which may be applied to almost any case with different localizations of the meatus. Later, two new methods, advancement of the urethra and preputial island flap techniques, were added to the surgical algorithm. Because acceptable results were observed, the authors have insisted on using these four techniques for all hypospadias cases since 1972. Complication rates (mainly fistula formation) were quite high (50 percent) in their early series of adults as a result of erection and hematoma formation. The complication rate of their patient population, which is now mainly composed of preschool children, has decreased to 7 to 8 percent, primarily as a result of careful selection of appropriate techniques for each individual case, the development of better surgical materials and equipment, and taking necessary precautions for postoperative care. A brief summary of modern hypospadias repair techniques is presented in four major classes. The results of the authors' 30-year experience and the precautions necessary to avoid postoperative complications are evaluated. The authors conclude that the four modern techniques and their modifications should be performed meticulously for successful hypospadias repair.

Polydactyly: a study of four generations of a Turkish family including an affected member with bilateral cleft lip and palate.

Polydactyly is one of the most common congenital deformities of the hands. It can occur as an isolated disorder, in association with other malformations of the hands or feet, or as part of a syndrome. It can occur sporadically but it can also be inherited with a mainly autosomal dominant inheritance. We present a Turkish family with affected members in four generations. Bilateral duplication of the second digit in both hands and feet with 24 digits in total was the most common pattern, but one affected member had 26 digits: seven on each hand and six on each foot. In addition, another affected member had complete bilateral cleft lip and complete cleft palate combined with bilateral hand and foot polydactyly without any syndromic association. The pedigree of the affected members of this family suggests an autosomal dominant mode of inheritance, but genetic expression is variable.
