History: 50 year old male with mouth pain and swelling. In the suprahyoid neck, the superficial layer of the deep cervical fascia also splits, forming the masticator space and the submandibular and parotid gland capsules . While diagnosis and treatments are often merely clinical, approximately 10% to 20% of deep neck infection complications are potentially life threatening. The muscles of mastication are enclosed in a layer of fascia, formed by cervical fascia ascending from the neck which divides at the inferior border of the mandible to envelope the area. The masticator space contains the temporalis, masseter, and pterygoid muscles, the ramus of the mandible, the mandibular nerve (V3 branch of the trigeminal nerve), the pterygoid venous plexus, and the … RADIOLOGY: HEAD AND NECK DR VIBHAY PAREEK RADIATION ONCOLOGY JUPITER HOSPITAL.

Clinicians divide the superficial structures of the neck into triangles using the superficial musculature. superficial, middle, and deep. It comprises 3 layers i.e. Localization of lesions to a particular space allows the generation of a limited radiologic differential diagnosis. Inferior to the hyoid bone, the superficial or investing layer of the deep cervical fascia divides into anterior and posterior leafs to attach to the respective borders of the suprasternal (jugular) notch, forming a small space ~2 cm superior to the manubrium 1-3.. The posterior cervical space is defined as the area in the posterolateral portion of the neck from the skull base to the clavicles deep to the sternomastoid and trapezius muscles but superficial to the prevertebral space. A transspatial, multilocular mass with fluid-fluid levels at MR imaging and a lack of phleboliths is suggestive of the diagnosis ( 2 , 12 , 13 ). Trismus often complicates evaluation of masticator space disease. Deep Neck Spaces Suprahyoid: 2.Parapharyngeal Space (pharyngomaxillary space ) Superior—skull base-petrous portion of temporal bone vs. sphenoid Inferior—hyoid Anterior—ptyergomandibular raphe Posterior—prevertebral fascia Medial—buccopharyngeal fascia Lateral—superficial layer of deep fascia,medial pterygoid and parotid .

Gross anatomy. The superficial temporal and the deep temporal spaces are sometimes together called the temporal spaces. Localization and patterns of … The deep lymph nodes, predominantly centered along internal jugular veins, are very well-known to radiol … CT anatomy of Neck Spaces RV. Radiologists use the deep layers of cervical fascia to divide the neck into compartments (spaces). Its principal contents are fat, the spinal accessory nerve, and lymph nodes. The deep cervical fascia consists of three separate but related fascial layers that encircle structures in the neck and allow anatomic compartmentalisation into the deep spaces of the head and neck.Each layer contributes to the carotid sheath.See the separate articles for further details: superficial layer of the deep cervical fascia; middle layer of the deep cervical fascia Select a zone . In addition, the cervical viscera with unique… In this article we present a pictorial essay of neck masses in children and provide a diagnostic approach based on the location of the lesion and whether it is cystic or solid. how are the neck spaces divided? The spaces approach to the head and neck is based on compartments defined by the layers of the deep cervical fascia. The submandibular space is posterolateral to the sublingual space and contains the superficial lobe of the submandibular salivary gland and lymph nodes . Contrast enhanced CT 1 Parapharyngeal space.

Radiology 174:65-71, 1990 12. The masticator space is a distinct deep facial space, bounded by the superficial layer of deep cervical fascia and containing the four muscles of mastication and the ramus and posterior body of the mandible. This paper was originally presented at the American Society of Neuroradiology 42nd Annual Meeting, Washington State Convention & Trade Center, … INTR0DUCTION Basis for dividing neck into spaces and compartments : arrangement of superficial and deep layers of cervical fascia The importance of this spaces is that they may limit to some degree the spread of most infections and some tumors A proper understanding of their anatomy will also aid in the diagnosis of various conditions. This is a submandibular space abscess. These masses may originate in the skin, subcutaneous fat, muscle, or bone. 5 Mucosal space. The suprasternal space (of Burns) is a space of the inferior neck..

The submandibular space is superior the hyoid bone, lateral or superficial to the mylohyoid muscle sling, and deep to the platysma muscle. Superficial palpable masses of the head and neck are common in the pediatric population, with the vast majority of the lesions ultimately proven to be benign. Its principal contents are fat, the spinal accessory nerve, and lymph nodes. Neck spaces by Dr. Akshaykumar, FRCR, DNBIntroduction to radiological anatomy.

Figure 1: Delicate superficial cervical fas-cia overlying external jugular vein and fat following division of platysma over the lateral neck Deep Cervical Fascia (Figures 2-4) This envelopes the deep neck spaces; hence an understanding of its anatomy is key to managing deep neck sepsis. Head and neck anatomy is some of the most complex anatomy in the human body. Then in the late 1980s and early 1990s, the spaces concept in the neck was reintroduced from a radiologic perspective, which enabled the radiologists to better understand the spaces of the neck and their components (Table 1). posterolateral part of the neck extending from the mastoid tip and base of skull to the clavicles 1,2; most of the volume is in the infrahyoid neck, with some extension into the suprahyoid neck 1; between superficial layer of the deep cervical … Hughes KVr, Olsen KD, McCaffrey TV: Parapharyngeal space neoplasms. These spaces are present in the neck between the layers of cervical fascia. Superficial palpable masses of the head and neck are common in the pediatric population, with the vast majority of these lesions ultimately proven to be benign ( 1 – 3 ).
