Lingual thyroglossal duct cysts (LTGDCs) are clinically rare and easily misdiagnosed as epiglottic cysts. Misdiagnosis leads to mistreatment; thus,simple diagnosis is important. This study aimed to investigate the characteristics of LTGDCs with flexible laryngoscopy and imaging, improve their diagnosis and explore surgical methods for patients undergoing an initial operation and patients with recurrence.In total, 10 patients with LTGDCs were admitted from April 2014 to December 2020.By reviewing the diagnosis and treatment of the first typical case, the characteristics of LTGDC under flexible laryngoscopy were summarized. According to these characteristic manifestations, a clinical diagnosis of LTGDC was made correctly in the other 9 patients. All 10 patients underwent preoperative CT of the neck and sagittal reconstruction and thyroid ultrasound.Of the 10 patients, the first 2 patients had recurrent LTGDCs after several operations and underwent Sistrunk surgery. The remaining 8 patients were newly diagnosed and underwent endoscopic radical resection with low-temperature coblation; of these patients, 7 had no recurrence, and 1 underwent Sistrunk surgery after developing short-term recurrence. All patients were followed up for 5 months to 6 years after the last operation and were without recurrence.LTGDCs are easily misdiagnosed as epiglottic cysts in the clinic. A correct clinical diagnosis can be made based on the characteristics according to flexible laryngoscopy. To determine the relationship between the cyst and hyoid bone, CT was performed. The surgical method was chosen based on the relationship between the cyst and hyoid bone and history of recurrence.
