RESUMO

OBJECTIVE: The surgical flap delaying has been shown to be effective in preventing partial flap loss or in preparing larger flaps. However, there is no gold standard flap delay method in the literature. In this study, the authors aimed to compare 3 types of surgical delay methods to determine which model would increase more flap survival. The authors also investigated the effect of delay methods on circulating mononuclear leukocytes as a parameter of DNA damage. METHODS: Twenty-four Sprague-Dawley male rats were divided into 4 groups. All subjects had a 10 × 3 cm modified McFarlane flap. Surface area measurements, biopsies, and blood samples were taken on the day of sacrification; 7th day for the control group and 14th day for delay groups. RESULTS: Between incisional surgery delay groups, a significant difference was found in necrosis and apoptosis in the bipedicled group, and only necrosis in the tripedicled group compared to the control. In terms of DNA damage, it was found higher in all experimental groups than in the control group. CONCLUSIONS: Both incisional surgical delay procedures' results were meaningfully effective when only incisions were made without the elevation of flaps. In conclusion, bipedicled incisional surgical delay seems to be the most effective method in McFarlane experimental flap model whereas two-staged surgeries may increase the risk of systemic toxicity.

RESUMO

BACKGROUND: There are many variables that influence nose tip harmony. Even in a rhinoplasty that appears successful in profile, one may see nostril asymmetries, alar retractions, or irregularities in the soft triangle, and patients express their dissatisfaction with these simple deformities. OBJECTIVES: In this study, we define the ratio of caudal and cephalic excess of the lower lateral cartilage. We evaluate whether it is possible to eliminate nostril asymmetries and alar retractions by means of supporting the facet polygon with the help of a lower lateral cartilage auto-rim flap, a technique we have developed in our rhinoplasties. METHODS: The auto-rim flap was used successively on 498 primary rhinoplasty patients on whom the same surgeon operated between May 2013 and June 2015, performing marginal incisions. RESULTS: Of the 498 patients in the series, only 1 of the first 10 required a revision due to tip asymmetry related to the auto-rim flap. A minimal nostril asymmetry that did not require intervention occurred in 10 patients. In none of the patients could an increased alar retraction be seen postoperatively. All patients exhibited alar cartilage in the anatomically correct position. CONCLUSIONS: With the auto-rim flap technique, a part of the caudal excess of the alar cartilage remains as a flap in the facet region; therefore, there is no need in the cephalic region to perform more of an excision than what is strictly necessary. LEVEL OF EVIDENCE: 4 Therapeutic.

RESUMO

BACKGROUND: In underdeveloped countries one-stage definitive repair of cleft lip and palate is considered for late-presenting patients. MATERIALS AND METHODS: A total of 25 patients with unoperated cleft lip and palate more than 2 years of age were enrolled in this study for one-stage simultaneous repair of cleft lip and palate. According to Veau-Wardill-Kilner push-back technique, 2 flap palatoplasties were performed for palatal repairs; all of the lips were repaired with the Millard II rotation-advancement technique. RESULTS: The authors experienced no perioperative or postoperative life-threatening complications. With respect to the registered operation periods, longer times were required to perform these double operations, but this elongation is shorter than the sum of the periods if the 2 operations had been performed separately. Although the authors were unable to evaluate the late postoperative results because the authors could not follow-up the patients after they were discharged the day after surgery, the early results related to the success of the operation without any surgical complication were prone to meet the parents' and patients' expectations. DISCUSSION: The authors presented their experiences with many volunteer cleft lip and palate trips to third world countries; however the structure of this article is not a new hypothesis and data based to support a scientific study, but observations are objective to get a conclusion. To perform one-stage definitive repair of the cleft lip and palate in late-presented patients was the reality that they had only 1 chance to undergo these operations. According to the terms and conditions of this challenging operation, one-stage simultaneous repair of cleft lip and palate is a more demanding and time-consuming procedure than is isolated cleft lip repair or cleft palate repair. Although technically challenging, single-stage repair of the whole deformity in late-presenting patients is a feasible, reliable, successful, and safe procedure in authors' experience.

RESUMO

Epidermoid cyst located in cranium is uncommon and usually diagnosed with a growing mass leading to symptoms. Asymptomatic intradiploic epidermoid cyst has not been reported yet. In this study, incidental diagnosis of asymptomatic cyst and potential impact of that cyst on surgical planning of a patient with craniosynostosis are presented.
