Lateral saccular cysts of the larynx. Aetiology, diagnosis and management

  • M. Hossam Thabet and Hesham Kotob

Abstract

Lateral saccular cysts have been diagnosed in 17 patients. Definitive diagnosis was made by computed tomography (CT) that showed a fluid-filled cystic swelling of the saccule with no air fluid level in all patients. Fifty-three per cent of cysts were bulging through the thyrohyoid membrane. They were hugely enlarged in 18 per cent, moderately enlarged in 24 per cent, and slightly enlarged in 12 per cent of patients. One patient (six per cent) showed bilateral cysts. Lateral saccular cysts were primary in origin in 82 per cent of patients and secondary to prolonged intubation, hemilaryngectomy, and laryngoscleroma in 18 per cent of patients. Surgical excision via a lateral cervical approach was performed in eight patients, whereas endoscopic CO2 laser vestibulectomy was performed in nine patients.

Endoscopic vestibulectomy with CO2 laser proved to be an efficient and safe procedure for excision of small and medium-sized cysts with a diameter equal to or less than 3 cm in the greatest dimension. The external approach appears more efficient than laser vestibulectomy in excision of huge cysts, as 22 per cent of patients undergoing laser surgery showed a recurrence.
