Cysts and fistulae related to the second and third pharyngeal pouches are described. These anomalies probably occur more often than presumed. Unilateral recurring infections of the tonsillar region, including parapharyngeal abscess, may be caused by anomalies related to the second pouch. Third pouch anomalies are located in the piriform recess. Cysts may reach a size that causes obstruction to the larynx and hypopharynx, while diverticulae cause few symptoms.
描述了与第二和第三咽囊相关的囊肿和瘘管。这些异常情况可能比预想的更常见。扁桃体区域的单侧反复感染，包括咽旁脓肿，可能由与第二咽囊相关的异常引起。第三咽囊异常位于梨状窝。囊肿可能会增大到导致喉和下咽梗阻的程度，而憩室则很少引起症状。
