Background:
This study aimed to identify the anatomy of retaining ligaments in the nasal region and understand their function via dissection of Asian cadavers.
Methods:
Between July 2020 and May 2023, 19 cadavers-11 fresh-frozen Koreans and 8 formalin-fixed Japanese-were examined. A midline vertical incision was made from the glabella to nasal tip, allowing exploration of supra-periosteal and supra-perichondrial planes. Vertically oriented, firm ligamentous structures connecting the nasal framework to the overlying skin-soft tissue envelope were carefully observed.
Results:
In all cadavers, 3 distinct retaining ligaments were consistently identified and named as superior, middle, and inferior nasal retaining ligaments. The superior nasal retaining ligament attached to the nasal bone at the level of the canthus, whereas the middle nasal retaining ligament attached at the nasal keystone area. The inferior nasal retaining ligament, also known as the vertical scroll ligament, connected the nasal superficial musculoaponeurotic system to the junction between the upper and lower lateral cartilage.
Conclusions:
Three nasal retaining ligaments observed and named in this study are fibro-ligamentous structures originating from the periosteum and fascia, supporting nasal shape, skin, and soft tissue positioning. Release of the nasal retaining ligaments would enable lengthening and augmenting the entire nasal structure for achieving successful outcomes in Asian rhinoplasty.

Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
