- W3029738081 abstract "ObjectiveTo explore the morphological changes of inferior cornu of thyroid cartilage (ICTC) malformation in congenital pyriform sinus fistula (PSF) in children.MethodsOne hundred and seventy-one patients were diagnosed with PSF and performed endoscope-assisted surgical excision from July 1999 to December 2016. Abnormal structure around the fistula (mainly for the ICTC) was found in 8 patients (male 7, female 1) during operation. The age-of-onset ranged from the first day of birth to 15.4 years (mean, 5.8 years). The average operative age was 8.6 years (23 months to 15.5 years). All the fistulas located on the left side. Retrospective investigation of clinical history and operative records of the 8 cases was carried out. The relationship between the fistula and ICTC was recorded detailed. According to the anatomic variations of ICTC, fistula were specified, recorded and reviewed. The type of ICTC were classified based on the abnormal development, and made appropriate surgical management according to the classification.ResultsThere were 8 patients with abnormal ICTC in 171 PSF patients (4.68%). The anatomic variations of ICTC were classified into 3 types: type Ⅰ (dysplasia of ICTC), 1 patient, the fistula is at some distance from the ICTC; type Ⅱ (cartilage fusion, ICTC was bonded with cricoid cartilage), 3 patients the fistula penetrated through the anterior or posterior to ICTC; type Ⅲ (obtuse ICTC), 4 patients, the fistula penetrated through the center of the tip of ICTC. Separated the fistula proximally, and then ligation cutting for type Ⅰ. For type Ⅱ, we had to cut a little bit of ICTC and pull it inward and upward in order to expose the fistula adequately. For type Ⅲ, a little bit of ICTC also should be cut, and then separated the fistula. All the 8 patients remained asymptomatic for 4 to 105 months. No complications occurred and no fistula recurrence after surgery.ConclusionsPSF in children could be accompanied with dysgenesis of ICTC. Understanding the anatomic variations is helpful for identifying the fistula and excising completely in operation, and decreasing the operative trauma at the same time.Key words: Pyriform Sinus; Fistula; Child; Thyroid cartilage; Dysplasia" @default.
