Angka Keberhasilan Fistulektomi pada Pasien Fistula Preaurikula di RSUPN Dr. Cipto Mangunkusumo = Succes Rate of Fistulectomy in Preauricular Fistula Patients at Cipto Mangunkusumo National General Hospital.

Latar Belakang: Fistula preaurikula disebut juga dengan kista preaurikula, sinus preaurikula, preauricular pit, preauricular tract, dan fissura preaurikula merupakan bentuk malformasi kongenital jinak dari jaringan lunak yang ditandai dengan adanya cekungan disekitar telinga luar. Insiden fistula preaurikula mencapai 10% dari populasi. Angka kejadian infeksi berulang pasca fistulektomi sebesar 0-42%. Belum ada data mengenai fistula preaurikula di Indonesia. Tujuan: Mengetahui angka keberhasilan fistulektomi pada pasien fistula preaurikula (infeksi berulang) di RSCM. Metode: Pada penelitian kohort retrospektif ini dilakukan wawancara, pemeriksaan fisik serta pengambilan foto telinga pada subjek penelitian. Data preoperasi subjek diambil dari rekam medis. Hasil: Didapatkan 42 pasien (48 telinga) fistula preaurikula yang telah dilakukan fistulektomi di Rumah Sakit Umum Pusat Nasional Dr. Cipto Mangunkusumo sejak tahun 2019 sampai 2024. Dua dari 48 telinga mengalami infeksi berulang pasca fistulektomi. Dari 10 subjek yang memiliki riwayat insisi sebelumnya, ditemukan sebanyak 2 telinga mengalami infeksi berulang, sementara 8 telinga tidak mengalami infeksi berulang (p=0.04). Dari 9 telinga yang memiliki letak fistula dengan tipe preaurikular, sebanyak 2 telinga mengalami infeksi berulang pasca fistulektomi (p=0.032). Kesimpulan: Insiden keberhasilan fistulektomi pada pasien fistula preaurikula di RSCM mencapai 95.8% dengan hanya 4.2% (2 telinga) mengalami infeksi berulang. Terdapat hubungan antara adanya riwayat insisi sebelumnya dan letak fistula preaurikula dengan kejadian infeksi berulang.

Background: Prerauricular fistula, also reffered to as preauricular cyst, preauricular sinus, preauricular pit, preauricular tract, or preauricular fissure, is a benign congenital malformation of the soft tissue characterized by a small depression near the external ear. Preauricular fistula affects approximately 10% of the population. The recurrance rate following fistulectomy ranges from 0-42%. Moreover, there is no research about preauricular fistula in Indonesia. Objective: To determine the success rate of fistulectomy in patients with preauricular fistula, particularly those with recurrent infections at Cipto Mangunkusumo National General Hospital (CMGH). Methods : In this retrospective cohort study, interviews, physical examinations and photographic documentation of the ears were conducted. Preoperative data were retrieved from medical records. Results: A total of 42 patients (48 ears) with preauricular fistula who underwent fistulectomy at Dr. Cipto Mangunkusumo National General Hospital between 2019 and 2024 were included. Recurrent infection occurred in 2 out 48 ears after fistulectomy. Among 10 subjects with a history of prior incision, 2 ears developed recurrent infection, while 8 ears did not (p=0.04). Of the 9 ears with preauricular-type fistula location, 2 experienced recurrent infection after fistulectomy (p=0.032). Conclusion: The success rate of fistulectomy in preauricular fistula patients in CMGH was 95.8%, with only 4.2% (2 ears) experiencing recurrent infection. A significant association was found between a history of prior incision and the location of the fistula with the occurrence of recurrent infection.
