TISSUE SPACES IN THE NECK

These are potential spaces with loose connective tissue which can be invaded by infection.

1. PREVERTEBRAL SPACE - behind the prevertebral fascia is the closed prevertebral space from which the only escape is through perforation of the fascia. An abscess from the cervical vertebra may lift this fascia down to T3 body.

2. ALAR/RETROPHAYNGEAL SPACE - immediately in front of the PREVERTEBRAL FASCIA is the space that extends from the BOS to the diaphragm. This extends behind the oesophagus to the posterior mediastinum. In the neck it lies b/w the PREVERTEBRAL FASCIA + BUCOPHARYNGEAL FASCIA.

3. PARAPHARYNGEAL SPACE - by the side of the pharynx, bound laterally by the pteygoids + parotid sheath.

4. SUBMANDIBULAR SPACE - extends above the investing layer of fascia b/w the hyoid bone and mandible to the mucous membrane on the floor of the mouth. It contains the myelohyoid, sublingual and submandibular glands.
