USE OF GUIDE PROBING OR METHYLENE BLUE STAINING DURING THE CONGENITAL PREAURICULAR FISTULA SURGERY
1Bingöl Devlet Hastanesi, Kulak Burun Boğaz Kliniği, Bingöl, Türkiye2Selçuk Üniversitesi Meram Tıp Fakültesi, Kulak Burun Boğaz Anabilim Dalı, Konya, Türkiye Objective: Surgical results of the cases with preauricular fistula or cyst were evaluated, retrospectively.
Patients and Methods: Sixteen patients who underwent surgery (10 female, 6 male; Mean age: 20.1±9.3 year) were evaluated, retrospectively. Carefully history, otolaryngological examination, superficial ultrasonography and temporal CT or MRI were carried out on all cases. Either probe guide or methylene blue staining technique was preferred to manage the cases with preauricular fistula due to facilitate dissection of tractus during surgical operation.
Results: Fifteen cases (93.7%) had preauricular fistula whereas one case (6.3%) had preauricular cyst and 6 cases had bilateral disease. In the cases who underwent methilen blue injection technique, a tattoo was observed on skin in one patient. In both groups, one recurrence was observed.
Conclusions: Recurrence can occur if limited tractus resection were performed. Methylene blue staining technique which can be used for obtaining total resection of the fistula tractus may have led to tattoo on the surgical area. For this purpose, probe guide technique should be selected to prevent this problem.
