Parapharyngeal abscess
Parapharyngeal abscess
Introduction
Parapharyngeal abscess is a deep neck abscess. It is also known as abscess of pharyngomaxillary or lateral pharyngeal space. Parapharyngeal abscess involve the parapharyngeal space.[1] Parapharyngeal space is lateral to the superior pharyngeal constrictor and medial to the masseter muscle, this space is divided by styloid process into anterior and posterior compartment. This space contains the carotid artery, internal jugular vein, numerous nerves.
Epidemiology
Both sex are equally affected Any age group can develop a parapheryngeal abscess but it is most commonly seen in children and adolescents.[2] Immunocompromised adults are the high risk people.[3]
Aetiology
Infection can occur from:
- Pharynx: acute and chronic infection of tonsil and adenoids
- Teeth: dental infection occurs from lower last molar tooth
- Ear: bezold abscess and petrositis
- Other space: infection of parotid retropharyngeal space
- External trauma: penetrating injuries of neck, injection of local anaesthetic[4]
Clinical features
Symptoms
Fever, sore throat, odynophagia (painful swallowing), swelling in neck.
Signs
Anterior space abscess can cause trismus (spasm of jaw muscle) and hard mass formation along the angle of the mandible, with medial bulging of the tonsil and lateral pharyngeal wall. Posterior space abscess causes swelling in posterior pharyngeal wall. Trismus (spasm of jaw muscle) is minimal. Posterior abscess may involve structures within the carotid sheath, causing rigors, high fever, bacteremia, neurologic deficit, massive haemorrhage caused by carotid artery rupture.[5]
