A peritonsillar abscess (quinsy) is drained. The space in which pus collects is between the:

• A Tonsillar capsule and the superior constrictor muscle (peritonsillar space) ✓
• B Tonsil and superior constrictor muscle
• C Tonsillar capsule and the palatopharyngeus muscle posteriorly
• D Internal and external pterygoid muscles in the parapharyngeal space

Explanation

Peritonsillar abscess (quinsy) is a collection of pus in the peritonsillar space, which lies between the fibrous capsule of the tonsil and the superior constrictor muscle. Clinically, it presents with unilateral swelling of the tonsillar pillar, uvular deviation to the opposite side, trismus, and 'hot potato' voice. Drainage is by needle aspiration or incision through the soft palate above the upper pole of the tonsil. Spread into the parapharyngeal space via the superior constrictor is a serious complication.
