BACKGROUND Pyriform sinus fistula is a rare brachial pouch anomaly. However, it is difficult and risky to remove the fistula tract completely. Circumferential chemocauterization of the internal opening with trichloroacetic acid (TCA) for pyriform sinus fistula is simple, reproducible, reliable, and causes less morbidity. The aim of this study was to determine the feasibility of TCA chemocauteri...
Pyriform sinus fistula is a rare clinical entity and the precise origin remains controversial. The fistula is discovered among patients with acute suppurative thyroiditis or deep neck infection of the left side of the neck and is usually located in the left pyriform sinus. To the best of our knowledge, only a single tract has been reported to be responsible for pyriform sinus fistula infection....
AST is commonly associated with pyriform sinus-thyroid fistula in children. Radiologic findings of AST are documented in a few reports. We report a new sign we term the "emerging echogenic tract sign," which reflects a patent air-containing pyriform sinus-thyroid fistula on follow-up US. Recognition of this sign is an important finding suggesting an associated pyriform sinus-thyroid fistula in ...
Thirty-five specimens from total laryngopharyngectomy clinically diagnosed as squamous cell carcinoma of the pyriform sinus were studied. Patients receiving chemotherapy or radiotherapy were excluded. Pathological examinations revealed 26 (74.3%) precancerous lesions and early carcinoma of the pyriform sinus. Eight out of 26 cases were detected by gross examination. Most pathological findings w...
INTRODUCTION Pyriform sinus fistula is a congenital branchial pouch abnormality that is often overlooked as a cause of acute neck infection in children. Our aim is to demonstrate the value of various imaging modalities (ultrasound, computed tomography [CT], barium oesophagraphy) in its diagnosis. MATERIALS AND METHODS The preoperative imaging findings of 5 patients with surgically proven pyri...
Objectives. Pyriform sinus fistulae arise from disturbances in the development of the fetal third and fourth branchial pouches and are predominantly found on the left side. We report the rare case of a right-sided pyriform sinus fistula presenting as a lateral neck abscess. Study Design. Case report. Methods. A 24-year-old woman presented with a two-week history of right-sided neck abscess. A f...
IMPORTANCE Congenital pyriform fossa sinus tracts predispose to neck masses and neck abscesses in pediatric and occasionally adult patients. Traditional management involves open excision with substantial potential morbidity. Endoscopic management allows an alternative, less morbid treatment approach. OBJECTIVE To evaluate the long-term effectiveness of endoscopic cauterization as definitive t...
BACKGROUND Primary small cell carcinomas (SCCs) are uncommon in extrapulmonary sites and account for only 2.5% to 5.0% of all SCCs. SCCs in the pyriform sinus are rare and there is little information regarding this disease, especially on therapeutics. Herein, we present a case of successfully treated SCC in the right pyriform sinus that occurred in a patient with small cell lung carcinoma (SCLC...
A 2-year-old boy with recurrent abscesses of on the left side of the neck due to pyriform sinus fistula is presented. Pyriform sinus fistula may cause acute suppurative thyroiditis and induce anterior cervical swelling, as in this case. Cervical computed tomography and barium swallow X-ray examination are important methods to diagnose of pyriform sinus fistula. Nearly all reported pyriform sinu...
