Pyriform sinus fistula is a rare anomaly arising from 3rd or 4th branchial apparatus and has been recognized as one cause of acute suppurative thyroiditis or acute deep neck infection. Pyriform sinus fistula must be considered when a clinician is encountered recurrent left lower neck abscess and a history of repeated incision and drainage. The confirmation of the diagnosis is made when the fistula tract is identified on a barium swallow study and when the internal orifice of the fistula is found at the apex of pyriform sinus on laryngoscopic examination. A complete excision of the fistula tract has been proposed as a treatment of choice. However, in some cases it is very difficult to resect the tract completely because of severe inflammation and repeated drainage procedure. We present three cases of pyriform sinus fistula which are successfully treated by laryngomicroscopic chemocauterization using synthetic fibrin and $AgNO_3$.

Acute suppurative thyroiditis is rare, infectious thyroid disorder because the thyroid gland is resistant to infection. We report a 26-year-old man with acute suppurative thyroiditis due to a pyriform sinus fistula. He presented with anterior neck swelling and tenderness for 2 weeks. Antibiotic treatment failed to improve his symptoms and signs. Diagnosis was made by bariums studies, computed tomography scan and endoscopic examination. The pyriform siuns fistula was successfully treated by chemical cauterization, partial thyroidectomy and ligation of fistula tract.

The pyriform sinus fistula can cause a recurrent abscess in the neck and the current treatment of choice involves complete excision of the sinus tract. But, because of excisional difficult, chemical cautery has been intermittently used as a successful substitute. Recently we experienced a case of pyriform sinus fistula of 9 year-old female who was successfully treated with chemocauterization with trichloroacetic acid(TCA) and ligation of the internal opening of the fistula tract on suspension laryngoscopy. So we report this rate case with review of literatures.

Fourth branchial pouch anomaly is an extremely rare condition involving the pharyngeal apparatus with only about 30 cases having been reported in the last 20 years. It almost invariably occurs on the left side and typically presents with repeated episodes of neck swelling, recurrent thyroiditis, or repeated bouts of retropharyngeal abscess. This is a presentation of 2 patient with pyriform sinus fistula, presumably of fourth branchial origin, which, were successfully closed with 10ole trichloroacetic acid chemical cautery. Details of the cases along with the summary of embryology and fourth branchial anomaly are given.

Background and Objectives : Fourth branchial cleft cyst is a rare congenital anomaly which cause a recurrent cervical abscess. Complete excision of fourth branchial cleft cyst is difficult because of a complicated fistula tract. In addition to attempting chemocauterization with trichloroacetic acid (TCA) to avoid surgical complications, authors performed an electrocauterization to close internal opening of pyriform sinus. Materials and Methods : We reviewed ten patients of fourth branchial cleft cyst underwent TCA chemocauterization and electrocauterization simultaneously. Clinical characteristics including patient informations, medical records, treatment results were analyzed retrospectively. Results : Interval time until diagnosed with fourth branchial cleft cyst was variable from several days to decades. Five patients had a history of incision and drainage. Mean follow up period was 36.1 months and all patients were treated with no recurrence. Conclusion : TCA chemocauterization with electrocauterization can be a effective choice to reduce recurrence rate and ensure safety of patients of fourth branchial cleft cyst.

경부 염증을 주 증상으로 하는 이상와 누공의 치료로써, 전통적으로 외과적 절제술이 주로 시행되었으나, 근래에 들어서는 수술 관련 위험성이 적은 삼염화아세트산 소작술이 선호되고 있다. 본원에서, 2004년 5월부터 2013년 3월까지 컷 다운 튜브를 이용한 삼염화아세트산 소작술을 통해 이상와 누공을 치료한 5명 환자의 증례를 보고한다. 이전까지의 삼염화아세트산 소작술에서, 여러 도구를 이용해 누공의 입구만을 막는 시도를 했던 것과는 달리, 본 증례에서는, 컷 다운 튜브를 이용해 20~50%의 삼염화아세트산을 누공로에 주입함으로써, 이상와 누공 전장을 폐쇄하고자 하였다. 3명의 환자에서는 추적 관찰 중 재발 소견 없었으며, 2명의 환자는 추적 관찰 기간 중 재발하여 삼염화아세트산 소작술을 재시행하였다. 모든 증례에서 부작용 및 합병증은 발생하지 않았다.
