Malformações branquiais : revisão bibliográfica
| Resumo: | Branchial anomalies are important lesions that should be considered in the differential diagnosis of head and neck masses, representing about 30% of the congenital masses of this anatomic area. These lesions consist of a heterogeneous group of anomalies that arise from the incomplete obliteration of the branchial apparatus during embryological development. They can arise from any of the branchial arches and may present as cysts, fistulae or sinus but the most common lesions are cyst from the second branchial arch. Uncommonly these anomalies can be associated with other organic malformations. Branchial anomalies have risk of neoplastic transformation that can be related with irradiation or chronic inflammation. The definitive surgical treatment is difficulted by their heterogeneity and demands a full understanding of anatomy and embryology in order to avoid incomplete resections and the consequent recurrences. |
