The flap’s donor area was chosen due to its proximity to the primary defect ( Figure 3). The flap was elevated, positioned and sutured in the bloody area, covering the defect, leaving out the area of the external auditory meatus to heal by second intention. The preparation of a transposition flap harvested from the area anteroinferior to the auricular pavilion was the procedure chosen for repairing the operative wound. Surgery was performed with simultaneous histological analysis of borders and resulted in a large surgical defect ( Figure 2). Following the clinical diagnosis of BCC, the authors chose to completely surgically excise the lesion. The patient also referred to progressive ipsilateral hearing loss. At the clinical examination, an ulcer vegetative lesion with pearly borders was observed spanning the entire auricular concha, external auditory meatus and part of the lobule ( Figure 1). The authors describe the case of a patient with extensive BCC affecting part of the external auditory meatus and auricular concha, whose treatment by association of surgical techniques – flap-plasty associated with second intention closure of the external auditory meatus – resulted in excellent esthetic and functional outcomes.Ī 72-year-old, phototype III male patient sought care related to a lesion perceived 7 months earlier in the right ear. However, there was no increase in the risk of BCC regarding cumulative exposure - unlike what is observed in squamous cell carcinoma patients, which is another malignant keratinocytic neoplasia. A study suggested that intermittent exposure to the sun is closely related to the occurrence of BCC, and that the risk of developing this condition is proportional to the incidence of ultraviolet (UV) radiation in the geographical area where the patient dwelled during his or her first 20 years of life.
#External acoustic meatus skin
Intensely fair skin and presence of actinic keratoses are the personal risk factors most frequently related to the development of BCC. It is known that exposure to the sun is the most important risk factor for BCC, while sensitivity to the sun is the main predisposing factor related to the host. Basal cell carcinoma (BCC) is the most frequent skin cancers and has an ever growing incidence, meaning an important public health and financial issue for several countries. Non-melanoma skin cancer is the most common form of cancer in humans. Keywords: Carcinoma, Basal cell Dermatology Ear neoplasms Ear, external Surgical flaps
Due to the excellent aesthetic and functional outcomes, this technique should be considered as a therapeutic option for auricular lesions. The authors present the case of a patient with an extensive basal cell carcinoma affecting part of the external auditory canal and auricular concha, treated with a combination of surgical techniques: flap-plasty associated with second intention closure of the external auditory canal. Basal cell carcinoma is the most common cancer of them, the incidence of which is steadily increasing, implying an important public and financial health issue. Non-melanoma skin cancer is the most common type of neoplasia. This study was performed at the Universidade do Estado do Rio de Janeiro - Rio de Janeiro (RJ), Brazil.
