<p>The <b>submasseterric space</b> (also termed the <b>masseteric space</b>) is a <a href="Fascial_spaces_of_the_head_and_neck" title="Fascial spaces of the head and neck">fascial space of the head and neck</a> (sometimes also termed <a href="Fascia" title="Fascia">fascial</a> spaces or tissue spaces). It is a <a href="Potential_space" title="Potential space">potential space</a> in the face over the angle of the jaw, and is paired on each side. It is located between the lateral aspect of the mandible and the medial aspect of the <a href="Masseter_muscle" title="Masseter muscle">masseter muscle</a> and its <a href="Masseteric_fascia" title="Masseteric fascia">investing fascia</a>. The term is derived from <a href="https://en.wiktionary.org/wiki/sub-" class="extiw external" title="wikt:sub-">sub-</a> meaning "under" in Latin and <i>masseteric</i> which refers to the masseter muscle. The submasseteric space is one of the four <a href="Compartment_(anatomy)" class="mw-redirect" title="Compartment (anatomy)">compartments</a> of the <a href="Masticator_space" class="mw-redirect" title="Masticator space">masticator space</a>.<sup id="cite_ref-Hupp_2008_1-0" class="reference"><a href="#cite_note-Hupp_2008-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> Sometimes the submasseteric space is described as a series of spaces, created because the masseter muscle has multiple insertions that cover most of the lateral surface of the <a href="Ramus_of_the_mandible" class="mw-redirect" title="Ramus of the mandible">ramus of the mandible</a>.

<div class="mw-heading mw-heading3"><h3 id="Communications">Communications</h3></div>

<p>The communications of each submasseteric space are:

</p>

<ul><li>to the <a href="Buccal_space" title="Buccal space">buccal space</a> anteriorly,</li>

<li>to the <a href="Pterygomandibular_space" title="Pterygomandibular space">pterygomandibular space</a> (around the posterior margin of the mandibular ramus to its medial surface) and the parotid space posteriorly,</li>
