Fístula preauricular

Dermatología Rev Mex 01/2010; 54:279-286.

ABSTRACT REsuMEN La fístula preauricular, que consiste en una malformación congénita benigna de los tejidos blandos preauriculares, puede manifestarse aislada o asociarse con otras anomalías congénitas. Suele ser asintomática, aunque también puede complicarse por abscesos e infección sobreagregada. Se revisa la bibliografía actual respecto al origen de la enfermedad, a sus características clínicas y a sus asociaciones con otras anomalías congénitas. Se expone su abordaje diagnóstico y se describen sus características histopatológicas, el manejo terapéutico –desde las fístulas asintomáticas o cuando existe infección aguda– y las técnicas quirúrgicas utilizadas para su resección. Palabras clave: fístula preauricular, seno preauricular, fistulectomía. ABsTRACT Preauricular fistula is a benign congenital malformation of the preauricular soft tissues and may be isolated or associated with other con-genital anomalies. It is usually asymptomatic, but may also be complicated by abscesses and superimposed infection. We review the current literature regarding the etiology of the disease, clinical characteristics, and associations with other congenital developmental abnormalities. This paper describes the diagnostic approach and gives an overview of histopathologic characteristics and its therapeutic management from asymptomatic fistulas, when there is acute infection and the surgical techniques used for resection.

    ABSTRACT: The presence of various types of birthmarks was determined in 3,345 Chinese infants under 48 hours of age. Mongolian spots were present in 86.3% of the studied infants. Vascular lesions included salmon patch (22.6%), port-wine stain (0.4%), and strawberry marks (0.7%). Nevocellular nevi (1%), sebaceous nevi (0.1%), and café au lait spots (0.4%) were also found. The following non-birthmark skin changes were observed: erythema toxicum neonatorum (33.7%), preauricular tags (1.3%), preauricular pits (2.5%) and a hyperpigmented scrotum (31.3%; in 1,727 male infants), which was related to the presence of mongolian spots.

    ABSTRACT: Preauricular sinuses (ear pits) are common congenital abnormalities. Usually asymptomatic, they manifest as small dells adjacent to the external ear near the anterior margin of the ascending limb of the helix, most frequently on the right side. Preauricular sinuses can be either inherited or sporadic. When inherited, they show an incomplete autosomal dominant pattern with reduced penetrance and variable expression. They may be bilateral, increasing the likelihood of being inherited, in 25-50% of cases. Preauricular sinuses are features of other conditions or syndromes in 3-10% of cases, primarily in association with deafness and branchio-oto-renal (BOR) syndrome. When other congenital anomalies coexist with these sinuses, auditory testing and renal ultrasound should be considered. Sinuses may become infected, most commonly with gram-positive bacteria, in which case their exudates should be cultured and appropriate antibiotics administered. Recurrent infection is a clear indication for complete excision and provides the only definitive cure. Recurrence rates after surgery range from 9% to 42%. Meticulous excision by an experienced head and neck surgeon minimizes the risk of recurrence.

    ABSTRACT: The authors studied 45 cases of congenital aural sinuses. Aural sinuses were observed on both sides in 17 cases (37.8%) and in girls (24 cases, 53.3%). Family history was positive in 12 cases (26.6%), and history of local infection was present in 40 cases (88.9%). The opening of aural sinuses was located most frequently in the marginal helicine region (36 cases, 80%). Microsurgery was extremely effective for accurate determination of the margins of intricately ramified aural sinuses, their detachment from surrounding tissues, and their total resection. Complete resolution without postoperative complications was achieved in 43 cases (95.6%).
