A retractor has hooked back the digastric muscle and facial artery, and drawn theinferior angle of the tonsillar wound forcibly downwards. This disi^ositionenables us to see: behind, the anterior aspect of the parotid pouch; in front,the posterior pole of the submaxillary gland; on the outside, the lingual nerve,internal pterygoid muscle, and ascending ramus of inferior maxilla; below, asmall cutaneous incision. This is the incision which we use in attacking thetonsil through the subangulo-maxillary region. 158 SURGICAL THERAPEUTICS AND OPERATIVE TECHNIQUE the external and internal carotid arteries, the internal jugular vein, and anumber of nerves—on the outside, the hypoglossal; between the two carotidarteries, the glosso-pharyngeal; between the internal carotid artery andinternal jugular vein, the pneumogastric; and behind the internal jugularvein, the spinal accessory.
