The larygeal saccule, or laryngeal appendix is a small outpouching from the anterior ventricle, that varies considerably in size. Various benign laryngeal lesion can arise from this structure. Laryngoceles and saccular cysts represent abnormalities of the laryngeal saccule. The clinical manifestations depend on the size of the parent saccule, the presence or absence of a communication between saccule and larygeal lumen, and the presence or absence of inflammation. Carcinoma of the larynx may be found in association with a laryngocele, saccular cyst or even a laryngopyocele in an adult. A thorough radiologic and ednoscopic evaluation is undertaken to rule out an underlying carcinoma which may originate in the saccule and must be diligently search for by biopsies in the region of the saccular orifice.
