Auricular fistulas are often referred to as congenital preauricular fistulas and often require surgical treatment when infection occurs. The complexity of surgery is determined by the presence or absence of infection in the diseased tissue and the characteristics of the fistula’s subcutaneous course.
Auricular fistulas are mostly congenital, most often detected at birth, the fistula is located near the foot of the auricle, the fistula is unilateral or bilateral, and asymptomatic cases may be left untreated. The disease can appear in front of the ear or behind the ear fistula, acute infection can be characterized by local redness, swelling and pain, rupture and pus. In cases of localized itching and overflow of secretions, surgical excision is appropriate after inflammation control.
Surgery includes simple fistula excision method and whole piece of preauricular tissue excision method. The former involves complete excision of the fistula along its course without affecting the surrounding tissues, while the latter involves removal of the preauricular fistula and its surrounding tissues together, both of which are routine otorhinolaryngologic procedures.
The inflammation of this disease scar adhesion and fistula vagus, as well as the fistula branch more, more thin is often incomplete surgery and postoperative recurrence of common factors, so once the deafness of the infection is recommended to actively surgical treatment, the specific timing of the operation should seek the advice of a specialist.
