A gap between the upper border of the superior constrictor and the skull base • This gap is occupied by the pharyngobasilar fascia. • It gives passage to the levator palati, ascending palatine artery, and auditory tube. • 2. A gap laterally between the superior and middle constrictors • It gives passage to the following: • a. Stylopharyngeus • b. Glossopharyngeal nerve • 3. A gap laterally between the middle and inferior constrictors • This gap is closed by the thyrohyoid membrane. • The structures passing through this gap are: • a. Internal laryngeal nerve. b. Superior laryngeal artery. • 4. A gap between the two parts of the inferior constrictor • It is a weak area at the back of the pharynx called (Killian’s dehiscence) • 5. A gap at the lower border of the inferior constrictor, pierced by: • a. Inferior laryngeal artery. b. Recurrent laryngeal nerve. • 𝐖𝐡𝐚𝐭 𝐚𝐫𝐞 𝐭𝐡𝐞 𝐩𝐚𝐫𝐭𝐬 𝐨𝐟 𝐭𝐡𝐞 𝐢𝐧𝐟𝐞𝐫𝐢𝐨𝐫 𝐩𝐡𝐚𝐫𝐲𝐧𝐠𝐞𝐚𝐥 𝐜𝐨𝐧𝐬𝐭𝐫𝐢𝐜𝐭𝐨𝐫? • The inferior pharyngeal constrictor muscle subdivides into the thyropharyngeus and cricopharyngeus muscles. • The thyropharyngeus muscle is superior to the cricopharyngeus muscle, and during normal swallowing, the thyropharyngeus contracts while the cricopharyngeus relaxes to propel the food into the esophagus. • 𝐖𝐡𝐚𝐭 𝐢𝐬 𝐭𝐡𝐞 𝐠𝐚𝐩 𝐛𝐞𝐭𝐰𝐞𝐞𝐧 𝐭𝐡𝐲𝐫𝐨𝐩𝐡𝐚𝐫𝐲𝐧𝐠𝐞𝐮𝐬 𝐚𝐧𝐝 𝐜𝐫𝐢𝐜𝐨𝐩𝐡𝐚𝐫𝐲𝐧𝐠𝐞𝐮𝐬? • Killian's dehiscence (also known as Killian's triangle) is a triangular area in the wall of the pharynx between the cricopharyngeus and thyropharyngeus which are the two parts of the inferior constrictors. • 𝐖𝐡𝐚𝐭 𝐢𝐬 𝐙𝐞𝐧𝐤𝐞𝐫'𝐬 𝐝𝐢𝐯𝐞𝐫𝐭𝐢𝐜𝐮𝐥𝐮𝐦 (𝐩𝐡𝐚𝐫𝐲𝐧𝐠𝐞𝐚𝐥 𝐩𝐨𝐮𝐜𝐡)? • It is a false diverticulum originating within the posterior midline of the hypopharynx and above the cricopharyngeus (Killian's dehiscence). • It presents with dysphagia, retention of food debris within the diverticulum, halitosis, and possibly a neck mass. • 𝐈𝐬 𝐊𝐢𝐥𝐥𝐢𝐚𝐧'𝐬 𝐝𝐞𝐡𝐢𝐬𝐜𝐞𝐧𝐜𝐞 𝐚𝐧𝐝 𝐙𝐞𝐧𝐤𝐞𝐫'𝐬 𝐝𝐢𝐯𝐞𝐫𝐭𝐢𝐜𝐮𝐥𝐮𝐦 𝐬𝐚𝐦𝐞? • Zenker's diverticulum is a herniation of mucosa and submucosa through a defect in the posterior aspect of the pharyngoesophageal junction. • This defect occurs in an area of potential weakness (Killian's dehiscence) in the midline between horizontal and oblique fibers of the inferior constrictor muscle • 𝐖𝐡𝐚𝐭 𝐢𝐬 𝐭𝐡𝐞 𝐜𝐥𝐢𝐧𝐢𝐜𝐚𝐥 𝐢𝐦𝐩𝐨𝐫𝐭𝐚𝐧𝐜𝐞 𝐨𝐟 𝐩𝐢𝐫𝐢𝐟𝐨𝐫𝐦 𝐟𝐨𝐬𝐬𝐚? • 1. It is a site for the impaction of the forging body. • 2. It is a suite of occult carcinoma. • 𝐖𝐡𝐚𝐭 𝐚𝐫𝐞 𝐭𝐡𝐞 𝐬𝐢𝐭𝐞𝐬 𝐨𝐟 𝐢𝐦𝐩𝐚𝐜𝐭𝐢𝐨𝐧 𝐨𝐟 𝐟𝐨𝐫𝐠𝐢𝐧𝐠 𝐛𝐨𝐝𝐲 𝐢𝐧 𝐭𝐡𝐞 𝐭𝐡𝐫𝐨𝐚𝐭? • The tongue root (42.29%), epiglottic vallecula (19.40%), tonsil (18.21%), and piriform fossa (10.65%). • 𝐌𝐂𝐐: 💪 • 1. What is the nerve supply of the piriform fossa in the pharynx? • A. Recurrent laryngeal • B. External laryngeal • C. Internal laryngeal • D. Glossopharyngeal • 2. Which of the following muscles narrows the oropharyngeal isthmus? • A Styloglossus • B. Palatoglossus • C. Palatopharyngeus • D. Tensor palate • 3. Which of the following lymph nodes drains the palatine tonsils? • A. Juguloomohyoid • B. Jugulodigastric • C. Submental • D.
