Giant Epiglottic Inclusion Cyst

Area of Science:

• Otolaryngology
• Laryngeal Pathology
• Surgical Techniques

Background:

• Epiglottic inclusion cysts are exceptionally rare benign lesions of the larynx.
• Persistent pharyngeal foreign body sensation can be a symptom of these cysts.

Purpose of the Study:

• To report a case of a giant epiglottic inclusion cyst.
• To highlight the diagnostic utility of the 'apple sign' on CT scans.
• To evaluate transoral plasma resection as a treatment modality.

Main Methods:

• A 41-year-old female patient presented with a year-long foreign body sensation.
• Diagnostic tools included laryngoscopy and contrast-enhanced cervical CT.
• Surgical intervention involved suspension laryngoscopic coblation under fiber optic intubation.

Main Results:

• Laryngoscopy revealed a giant epiglottic cyst.
• CT imaging demonstrated the characteristic pedunculated 'apple sign'.
• Histopathology confirmed the diagnosis of an epiglottic inclusion cyst.

Conclusions:

• The 'apple sign' is crucial for accurate preoperative diagnosis and surgical planning.
• Transoral plasma resection is a safe, effective, and low-recurrence treatment for this rare laryngeal disease.
