The submandibular glands lay superficial to the suprahyoid and infrahyoid muscle groups and were covered by the inferior portion of the parotid gland.
Outcome of surgery can be predicted as cervicofacial lesions have more success rate than any other parts and infrahyoid lesions have more success rate than suprahyoid. [1] Age has no role towards outcome of the surgery.
The suprahyoid muscles are considered to be strategic for deglutition, since they participate in motor reflex mechanisms, lowering and stabilization of the mandible, elevation and forward movement of the hyoid bone, and have insertion with tongue musculature (9,10).
In the suprahyoid location, the carotid sheath does not have complete anatomical boundaries and may potentially communicate with the para- or RP space (10).
Additionally, they reported that resection of one arytenoid allows either the base of the tongue or suprahyoid epiglottis to form a tight laryngeal sphincter with the remaining arytenoid cartilage (10).
Coordinates are used to map the swallowing mechanics in the suprahyoid muscle group (#9 to the mandible [vectors #1 to #3) and in the thyrohyoid (#8 to #9), the stylopharyngeus (#7 to #3), the palatopharyngeus (#6 to #2), and the styloglossus and hyoglossus (#10 to #3) muscles.
First, we utilized a suprahyoid or posterior approach depending on the tumor sites (Figure 1).
Studies indicate that the tongue-pressure-on-the-palate exercises are effective in the rehabilitation of lingual strength [61, 62] and promote substantial activation of suprahyoid musculature [62].
They assessed the EMG activity of the masseter, temporalis, and suprahyoid muscles in 34 children aged 8-12 years: 17 children with TMD and 17 without TMD.
The inferior component was also suprahyoid. Therefore, it was felt that a lip-split mandibulotomy would give good access and delivery of the tumour.
A reduction in relapse is also observed with TMAO because the suprahyoid muscles are not disturbed during the alveolar segment advancement.
The head postured in a more forward position, would stretch the soft facial tissue layer covering the face and neck, especially the suprahyoid muscles.48
