tonsillar bed relations medial to lateral anatomy

Quick answer

Tonsillar bed, medial to lateral:
  1. Mucosa and fibrous capsule of the palatine tonsil
  2. Peritonsillar space containing loose areolar tissue
  3. Pharyngobasilar fascia
  4. Superior constrictor muscle
  5. Buccopharyngeal fascia
  6. Parapharyngeal space, containing the internal carotid artery, internal jugular vein, and cranial nerves IX to XII more posterolaterally
Clinically, the glossopharyngeal nerve (CN IX) lies deep to the superior constrictor and may be injured in deep tonsillar dissection.

palatine tonsil anatomy

I overcomplicated it. For the tonsillar bed from medial to lateral:
Tonsil → tonsillar capsule (pharyngobasilar fascia) → peritonsillar loose areolar space → superior constrictor muscle → buccopharyngeal fascia → parapharyngeal space.
The glossopharyngeal nerve is immediately deep/lateral to the superior constrictor.
