From: Necrotizing descending mediastinitis by Acinetobacter Baumannii in an out-patient: a case report
Deep neck space: | Characteristics: |
|---|---|
-Lateral pharyngeal space. (para pharyngeal space) | Is a space located in the upper neck above hyoid bone. -Base: jugular foramen, -Apex hyoid bone. -Medially: tracheal fascia -Laterally: superficial fascia, including parotid gland, pterygoid muscle, and limited laterally by mandible |
- Retro-pharyngeal space. | Directed longitudinally and inferiorly to posterior mediastinum -Posteriorly: pre-vertebral fascia -Anteriorly: posterior aspect of per-tracheal fascia -Inferiorly: T1–T6 level vertebrae |
-Sublingual space and sub-mental space | Separated by mylo-hyoid muscles. |
