Pharyngeal mucosal space abscess. A special entity that merits special
management: our experience in 106 cases.
Keypoints: • The presence of a pharyngeal mucosal space abscesses (PMA),
being confined between the pharyngeal mucosa and the pharyngeal
constrictor muscle, is considered rare. However, in our series
represented 14,3% of deep neck infections (DNIs), suggesting that they
may not be so rare as they are considered to be. • PMAs’ symptoms and
clinical findings are similar to those of other DNIs, but trismus and
neck swelling seem to be significant lower in PMAs. • Imaging studies
will set PMA diagnosis, while CT with contrast is the modality of
choice. • PMAs seems to be less dangerous than their deep-seated
counterparts, since its superficial location renders them amenable to
spontaneous drainage, aspiration, incision and drainage intraorally
obviating spread to deeper structures.
