Laryngoceles associated with laryngeal carcinoma

ABSTRACT

Laryngoceles and large saccules were found in 3.07% and 5.12% of patients with laryngeal carcinomas. CT proved to be very accurate more than endoscopy in detection of asymptomatic laryngocele associated with cancer larynx. However both endoscopy and CT are recommended in cases presented primarily with laryngoceles to rule out any underlying malignancy. Laryngoceles were bilateral in 50% of cases. Large saccules were ipsilateral in 60% [6/10], bilateral in 10% [1/10], and contralateral in 30% [3/10] of cases. Four patients with supraglottic tumors [4.54%] were associated with two bilateral symptomatic and two asymptomatic ipsilateral laryngoceles. Two patients with transglottic tumors [3.44%] showed asymptomatic ipsilateral internal and bilateral mixed laryngoceles. All asymptomatic laryngoceles were diagnosed by CT and postoperative examination of the specimens as patients presented usually with symptoms related to the tumor. Large saccules were found in 5.68% of supraglottic tumors, 4.76% of glottic tumors, and 5.17% of transglottic tumors. 60% [6/10] of large saccules were ipsilateral, 30% [3/10] were contralateral, and 10% [1/10] was bilateral
