Explanation:
Clinical features
- In Ludwig’s angina there is usually cellulitis of the tissue rather than frank abscess.
- Marked difficulty in swallowing (odynophagia).
- Varying degrees of trisumus.
- On involvement of sublingual space, floor of the mouth is swollen, oedematous and tongue seems to be pushed up and back.
- On involvement of the submaxillary space the submental and submandibular regions become swollen and tender and impart woody- hard feel. Tongue is progressively pushed upwards and backwards threatening the airway.
- Laryngeal edema may appear.
Complications
- Aspiration pneumonia and septicemia.
- Airway obstruction due to laryngeal edema or swelling and pushing back of tongue.
- Spread of infection to parapharyngeal and retropharyngeal space and thence to the mediastinum.
