Submandibular Space
A submandibular space infection is a bacterial infection of the floor of the mouth.
Submandibular space. Gross anatomy the sublingual space is a part of the floor of mouth 1. Symptoms include pain dysphagia and potentially fatal airway obstruction. The submandibular space is a suprahyoid deep compartment of the head and neck.
Water covered a large space at the end of the valley. 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. An extent or expanse of a surface or three dimensional area.
The submandibular space extends from the hyoid bone to the mucosa of the floor of the mouth and is bound anteriorly and laterally by the mandible and inferiorly by the superficial layer of the deep cervical fascia. Treatment includes airway management surgical drainage and iv antibiotics. The submandibular nodes are small usually measuring approximately 1 centimeter in a healthy adult.
The submandibular duct which brings lymph fluid to the node is approximately 5 to 6 centimeters. The mylohyoid muscle separates it superiorly from the sublingual space which communicates with it freely around the posterior border of the mylohyoid. The submaxillary space is a historical term for the combination of the submandibular submental and sublingual spaces which in modern practice are referred to separately or collectively termed the perimandibular spaces.
Bacteria can spread from an infected lower tooth to the tissue under and around the tongue. Diagnosis usually is clinical. The space corresponds to the anatomic region termed the submandibular triangle part of the anterior triangle of the neck.
As the sublingual space is not bounded by fascia posteriorly some authors consider the sublingual space a component of the submandibular space 2. It was first described by the german physician wilhelm frederick von ludwig in 1836. Terminology within this compartment all authors include the space within the submandibular triangle around the submandibular gland.
