The mandibular notch acts as a passageway for the masseteric
artery (accompanied by the masseteric
vein and nerve) to enter the deep surface the masseteric
muscle (Standring; Mohammad et al).
It represents second most common fractures of facial skeleton after nasal bone.1Its fractures are inherently unstable due to; corner stone position, attached superficial muscular aponeurotic system (SMAS) and strong masseteric
muscle downward pull.
The researchers found that flaps were reinnervated with facial and masseteric
nerves, with masseteric
nerves only, and with crossfacial nerves only in five, five, and two patients, respectively.
The flap was sutured to remnant parotid fascia and masseteric
fascia avoiding a direct or indirect hitch or compression on the branches of the facial nerve.
musculature is inserted in the mandibular angle anatomically and can cause overdevelopment of these angles because of its traction forces .
Contrast-enhanced CT (CECT) scan with cisternography revealed a large lobulated mass of size 81 x 53 x 82 mm in the left zygomatic and masseteric
region with intracranial extension (Figure 1(a)).

This axial T1-weighted MRI of the head and neck shows a hyperintense mass located in the right parapharygeal space and anterolaterally into the masseteric
Anatomically-based differential diagnosis for the masticator space * Muscles of mastication: Mesenchymal lesions (benign and malignant, such as hemangiomas and sarcomas), lymphoma, benign masseteric
hypertrophy, denervation atrophy, idiopathic fibrosis, metastases, myositis ossificans (Figures10B, 10C).
In our clinic, BTXA has been safely used for the treatment of bruxism, masseteric
hypertrophy, and sialorrhea.
The PMS is made up of masseteric
and medial pterygoid muscles.
Investigative therapies including gabapentin to "improve self-injurious behavior"1,9 and botulinum toxin masseteric
injections10 as well as globus pallidus deep-brain stimulation or dopamine replacement therapy "need to prove to be efficacious and safe in the long-term management of these patients"1 and (especially the latter) are not easily available or accessible in lowand middleincome countries such as ours.
