“…It was found in all of the 193 sides examined. Both Seward (1968) and Ziarah and Atkinson (1981) pointed out its importance as a landmark in surgical approaches to the submandibular region. They referred to it as "the angular tract of fascia" and considered it to be a thickening of the investing layer of deep cervical fascia.…”

The mandibulo-stylohyoid ligament is a consistently occurring connective tissue band or sheet that courses between the angle of the mandible and the stylohyoid ligament. Previously, in a few instances it has been variously named and described as a thickening of deep cervical fascia. Recently, Shimada et al. (1986) described the connective tissue thickening and named it the mandibulo-stylohyoid ligament because of its arrangement and attachments. In the present study the ligament was dissected in 99 adult cadavers (both white and black, 98 right sides, 95 left sides). It was present in all of the specimens examined and has been classified into three types according to refinements in its morphology. Type 1: The ligament was a thick, separate band that coursed from the region of the angle of the mandible to the stylohyoid ligament. Type 2: The ligament had the same attachments as Type 1 but was more extensive, being continuous with the stylomandibular ligament. Type 3: The ligament had the same attachments as Type 1 but was thin and less well developed. The Type 1 arrangement occurred 41% of the time, Type 2, 37% of the time, and Type 3, 22% of the time. The consistency and arrangement of the ligament suggests an important role of additional structural support in the region of the angle of the mandible and hyoid bone.

“…This persistence contributes to the natural delineation of the chin and jawline, resulting in tauter skin. This phenomenon can be attributed to the presence of resilient structures such as the insertion of the mentalis muscle at the chin, the mandibular ligament along the boundary of the chin and jawline, and the angular tract fascia anterior to the SCM muscle within the inner angle of the mandible 10,11 . These unyielding structures play a role in the phenomenon wherein lax tissues, when shifted toward firm structures, produce a naturally effective lifting effect, aligning with the author's perspective (Figure 1).…”

IntroductionFace‐lifting surgeries were once common among individuals over 60 years old due to skin laxity, but recent trends favor thread lifting in this age group. Understanding dynamic changes in facial anatomy during postural shifts is essential.MethodFresh cadaver studies have demonstrated the passage of threads through the superficial musculoaponeurotic system (SMAS) layer, confirming the efficacy of the technique. Proper insertion depth targeting SMAS repositioning, rather than superficial skin layers, is crucial.ResultThe natural movement of tissues secured by thread (N‐Cog and N‐Fix, N‐Finders Inc., Korea) insertion results in lifting effects. However, complications may arise if threads affect deeper facial muscles, leading to discomfort. Fibrous septa play a significant role in guiding thread placement, with different densities influencing thread maneuverability and tissue response during lifting.ConclusionProcedures targeting SMAS repositioning using threads aim to maintain the new position of relocated tissues. Understanding structural variations in facial regions informs thread selection and placement. Aligning threads with tissue movement and the intended SMAS layer positioning is vital to prevent complications. Balancing thread insertion depth and tissue traction is critical for successful outcomes. Modern thread lifting techniques prioritize SMAS repositioning, enhancing lifting effects while ensuring procedure safety and efficacy.

The mandibulo-stylohyoid ligament is a consistent large ligament that extends from the angle of the mandible to the stylohyoid ligament, with prolongations in the direction of the stylohyoid, posterior belly of the digastric and sternocleidomastoid muscles. The ligament partly separates the submandibular from the parotid gland. It is believed that this ligament should be included in anatomy textbooks, as it is important in both the clinical and surgical anatomic fields.
