Pharyngeal mucosal space abscess. A special entity that merits special management: our experience in 106 cases.

Abstract

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.
