What is Masticator space?
Abstract. 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. Trismus often complicates evaluation of masticator space disease.
What causes buccal space infection?
Buccal space infections – These arise primarily from mandibular or maxillary bicuspid or molar teeth, the apices of which lie outside of the buccinator muscle attachments. They are readily diagnosed because of marked cheek swelling but with minimal trismus or systemic symptoms (see Figure 4). Figure 5).
Which anatomical spaces are involved in a Masticator space infection?
Infection in the masticator space may spread to the parapharyngeal, parotid, or temporal space.
…
- The parotid space is enclosed by the superficial layer of the deep cervical fascia.
- The parotid space is crossed by the external carotid artery, the posterior facial vein, and the facial nerve.
What is Submasseteric space infection?
Submasseteric inflammation is a deep facial space inflammation, often progressing to mature abscess, and usually misdiagnosed as staphylococcal or streptococcal lymphadenitis or pyogenic parotitis. The hallmark of a masticatory space infection is trismus.
Where is the Masticator space located?
Description. The masticator space is a deep facial space that is outlined by the superficial layer of the deep cervical fascia and lies laterally and evenly in front of the prestyloid space, medial to the pharyngeal space and beneath the skull base.
What muscle closes the jaw?
The masseter muscle is one of the four muscles responsible for the action of mastication (chewing). When the masseter contracts it causes powerful elevation of the mandible causing the mouth to close.
How do you treat buccal space infection?
The usual protocol for the management of patients having odontogenic space infection is incision and drainage, removal of the focus and antibiotic along with supportive measures.
What are the symptoms of a jaw bone infection?
Jawbone infections/dental abscesses are caused when a dental cavity remains untreated.
Symptoms of a jaw bone infection or dental abscess include:
- Pain in the mouth or jaw.
- Redness or swelling.
- Drainage of pus from the area.
How do you know if you have a deep neck infection?
You will have a red or swollen throat, neck pain or stiffness, a bulge at the back or the throat, and ear pain. Body aches or chills and difficulties swallowing or breathing can also be a symptom. If you’re having any one of these symptoms you may want to consult a doctor for treatment.
How do you drain a Masticator space abscess?
The abscess is drained via a horizontal incision 2.0 to 2.5 cm below the lower border of the mandible. A subplatysmal flap is raised and the masseter muscle is breached to expose the abscess through the pterygomasseteric sling13. Drainage will be performed under local or general anesthesia.
What is the parotid space?
The parotid space is a roughly pyramidal space, the broad elongated base facing laterally, formed by cervical fascia overlying the superficial lobe of the parotid gland, and its apex pointing medially.It is traversed by the external carotid artery, retro-mandibular vein and facial nerve.
What is the function of lingual nerve?
The lingual nerve transports special visceral afferent (SVA) fibers from the chorda tympani responsible for taste perception in the anterior two-thirds of the tongue, and general visceral efferent (GVE) fibers responsible for secretory and motor innervation of the sublingual and submandibular glands [3].
What’s the weakest muscle in your body?
The Stapedius
The Stapedius is thought to be the weakest muscle. It is also the smallest muscle in the human body.
What is the kissing muscle called?
Orbicularis oris muscle
Orbicularis oris muscle along with the buccinator and pharyngeal constrictor form a functional unit, known as “buccinator mechanism” which has an important role in orofacial function (swallowing, sucking, whistling, chewing, vowel pronunciation, kissing).
What are the five signs of infection?
Know the Signs and Symptoms of Infection
- Fever (this is sometimes the only sign of an infection).
- Chills and sweats.
- Change in cough or a new cough.
- Sore throat or new mouth sore.
- Shortness of breath.
- Nasal congestion.
- Stiff neck.
- Burning or pain with urination.
What antibiotics treat mouth abscess?
The most common ones used for an abscess include:
- Amoxicillin.
- Azithromycin.
- Cefoxitin.
- Metronidazole.
- Penicillin.
What happens if a tooth infection spreads to your jaw?
Leaving an infection to spread to your facial bones may eventually necessitate surgical removal to stop it. Even in minor cases, a tooth infection can cause the bone structures of your jaw to weaken, making it hard to support your teeth.
What is the best antibiotic for jaw bone infection?
Treatment is with antibiotics and usually drainage. Penicillin was the drug of choice, but since many staphylococci are now penicillin-resistant, flucloxacillin or fusidic acid may be used.
Which antibiotic is best for neck infection?
Penicillin G is the drug of choice for those infections caused by streptococci, and nonpenicillinase-producing staphylococci, which represent the majority of aerobic organisms in deep neck abscess.
Is a neck infection serious?
Deep neck infections are a serious but treatable group of infections affecting the deep cervical space and characterized by rapid progression and life-threatening complications. These infections remain an important health problem with significant morbidity and potential mortality.
How do you drain a dog’s space infection?
Parenteral broad-spectrum antibiotic therapy including anaerobic coverage is indicated. Dental or oral surgical consultation for incision and drainage is the most definitive treatment for canine space abscesses. Extraction or endodontic treatment of the involved anterior maxillary teeth is usually necessary.
What CT scan shows the parotid gland?
Plain CT clearly showed parotid tumors in nine of the patients. CT combined with sialography was more helpful than plain CT for delineating the tumors in the other patients who had either tumors in high-density parotid glands or tumors of low density.
What is the best imaging for parotid gland?
magnetic resonance imaging (MRI)
Computed tomography (CT) scanning or magnetic resonance imaging (MRI) is useful for determining the extent of large tumors, for evaluating extraglandular extension, for determining the actual depth of parotid tumors, and for discovering other tumors in one gland or in the contralateral gland.
What happens if the lingual nerve is damaged?
Symptoms of lingual nerve damage can include, but are not limited to: A tingling sensation in the tongue. Numb areas of the tongue. A distinct loss of taste, or altered taste perception.
How do you test for lingual nerve damage?
A method for assessing lingual sensation is described, comprising sensory testing, using touch and moving two-point discrimination and patient subjective reporting. The clinical application is seen to be the evaluation of lingual nerve injury consequent upon lower third molar surgery.
