On plain radiography, prevertebral space should be less than 6 mm at C3 vertebral level in children; while in adults, the space should be less than 6 mm at C2 level and less than 22 mm at C6 level. Causes of enlarged prevertebral space could be edema, hematoma, abscess, tumors, and post surgical changes. [5]
The deep temporal space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space in the side of the head, and is paired on either side. It is located deep to the temporalis muscle. The inferior portion of the deep temporal space is also termed the infratemporal space.
In the head and neck, potential spaces are primarily defined by the complex attachment of muscles, especially mylohyoid, buccinator, masseter, medial pterygoid, superior constrictor and orbicularis oris. [6] Infections involving fascial spaces of the head and neck may give varying signs and symptoms depending upon the spaces involved.
The infratemporal space is the inferior portion of the deep temporal space, which is one of the four compartments of the masticator space, along with the pterygomandibular space, the submasseteric space and the superficial temporal space. [2] The deep temporal space is separated from the pterygomandibular space by the lateral pterygoid muscle ...
The submental space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space located between the mylohyoid muscle superiorly , the platysma muscle inferiorly , [ 1 ] under the chin in the midline.
A parapharyngeal abscess is a deep neck space abscess of the parapharyngeal space (or pharyngomaxillary space), which is lateral to the superior pharyngeal constrictor muscle and medial to the masseter muscle. [1] This space is divided by the styloid process into anterior and posterior compartments.
The parapharyngeal space is shaped like an inverted pyramid. Lateral and inferior to the parapharyngeal space is the carotid sheath, containing the internal carotid artery and cranial nerves IX, X and XI. Behind both the parapharyngeal space and carotid space lies the retropharyngeal space, and deep to this a potential space known as the danger ...
The submandibular space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space , and is paired on either side, located on the superficial surface of the mylohyoid muscle between the anterior and posterior bellies of the digastric muscle . [ 1 ]
