ABSTRACT
Abstract Objective: Various techniques have been described in the literature for prominent ear correction. These cartilage-preserving or cartilage-shaping techniques have their own advantages and disadvantages. We aim to achieve aesthetic and stable results with low complication rates using combinations of these methods. Herein, we present our results of prominent ear surgery with a modified bilateral fasciaperichondrial flap in combination with concha-mastoid and concha-scaphal sutures. Methods: Patients whose surgeries included a modified bilateral fasciaperichondrial flap for prominent ear deformities were included in the study. Patients' demographic data, pre- and postoperative Concha-Mastoid Angle (CMA) and upper-middle Helix-Mastoid Distances (HMD), follow-up time, complications, secondary operations, and postoperative Visual Analogue Scale (VAS) results were evaluated. With a postauricular fish-mouth incision, the bilateral fasciaperichondrial flap was planned into two: proximal- and distal-based. They were then elevated from the cartilage subperichondrially on the proximal side and supraperichondrially on the distal side. Concha-scaphal sutures were used to form an antihelical rim along with concha-mastoid sutures to reduce the concha-mastoid angle. Conchal cartilage resection was done if needed. Then, the bilateral fasciaperichondrial flaps were sutured together to cover the concha-mastoid and concha-scaphal sutures. Results: Between May 2017 and May 2021, 32 ears of 17 patients were operated on dueto prominent ear deformity. No hematoma or infection was observed in any patient, and there were no instances of recurrence, suture exposure, hypertrophic scars, or keloids. The satisfaction level of all patients was 8.2 ± 0.9 points on average according to the VAS. In the anthropometric measurements, a statistically significant difference was found between preoperative and postoperative sixth month CMA and HMD values. Conclusion: A combination of suture techniques and a modified bilateral fasciaperichondrial flap may be used in prominent ear cases, with low recurrence rates and high patient satisfaction. Level of evidence: III.
ABSTRACT
O vírus Epstein-Barr (EBV) é um conhecido vírus carcinogênico. A associação entre EBV e alguns tumores sugere que também pode haver correlação entre carcinoma de laringe e EBV. OBJETIVO: O presente estudo pretende determinar o papel do EBV na etiologia do carcinoma de laringe. MÉTODO: Estudo prospectivo sobre EBV por reação em cadeia da polimerase em tempo real em tecidos tumorais de 25 pacientes com carcinoma de laringe e 17 pacientes com lesões benignas de laringe; análise da relação entre presença de DNA viral e tabagismo, etilismo, localização e diferenciação tumoral. RESULTADOS: Não houve diferenças significativas entre os grupos de controle e de estudo para positividade da PCR para EBV (p > 0,05). Não foi identificada relação estatisticamente significativa entre positividade para EBV e diferenciação tumoral, localização da neoplasia, tabagismo ou etilismo (p > 0,05). CONCLUSÃO: Nossos resultados sugerem que, a despeito de sua identificação em alguns carcinomas espinocelulares de laringe, a presença de EBV não teve qualquer influência na patogenia do carcinoma de laringe.
Epstein-Barr virus (EBV) is a well-known carcinogenic virus, and the association of EBV with some tumours suggests that there may also be an association between laryngeal carcinoma and EBV. OBJECTIVE: The aim of this study is to determine the role of EBV in the aetiology of laryngeal carcinoma. METHOD: Prospective investigation the EBV with real time polymerase chain reaction in tumour tissues of 25 patients with laryngeal carcinoma and 17 patients with benign laryngeal lesions, and investigation of the relationship between the presence of viral DNA and patients' smoking habits, alcohol consumption, localization and differentiation of the tumour. RESULTS: There was no significant difference between the control group and patient group in terms of EBV polymerase chain reaction positivity (p > 0.05). Also we couldn't find a statistically significant relationship between EBV positivity and differentiation of the tumour, localization of the tumour, smoking and alcohol consumption habits (p > 0.05). CONCLUSION: Our results suggest that, although EBV is present in some of the squamous cell laryngeal carcinomas, its presence has no effect on the pathogenesis of laryngeal carcinomas.
