Obstructive sleep apnoea (OSA) is a prevalent condition and has been extensively managed with orthognathic surgery using a variety of surgical techniques. This case report describes the successful management of a 56-year-old Caucasian woman with a bimaxillary retrusive profile and macroglossia complicated by OSA and the combined use of orthodontics and orthognathic surgery to improve Apnoea-Hypopnoea Index while maintaining facial aesthetics. The non-extraction treatment plan included: (1) pre-surgical orthodontic treatment to maximise aesthetics and functional occlusion after surgery; (2) maxillomandibular advancement using down fracture of the maxilla (Le Fort 1 osteotomy) with counter-clockwise rotation as well as bilateral sagittal split osteotomy with septoplasty to aid increase in airway function; and (3) post-surgical orthodontic finishing and alignment with self-ligating fixed appliances. Optimum aesthetic and functional results as well as an increase in the airway volume were achieved, without compromising facial aesthetics, with the cooperation of two specialties and the use of state-of-the-art technology during the surgical planning stages.

Purpose: The harmony between the lips and the chin is an essential parameter in facial esthetics, and the mentolabial sulcus (MLS) represents the level of this harmony. This study aimed to assess the effect of MLS depth on facial profile attractiveness in long-face, short-face, and normal-face Iranian female individuals.
Methods: An observational study with a questionnaire was conducted, and a profile photograph of an Iranian female with class I occlusion was altered to create long-face, normal-face and short-face profiles with MLS depth ranging from 1 to 12 mm.

Methods: Adults with minimal, moderate, or severe temple hollows were randomized 2:1 to receive VYC-20L or no treatment.
Why Does an "Avatar Nose" Appear After Dermal Filler Injection? Insights From a Cadaveric Study on the Nasofrontal Ligament.
Dermatol Surg
January 2025
Division in Anatomy and Developmental Biology, Department of Oral Biology, Human Identification Research Institute, BK21 FOUR Project, Yonsei University College of Dentistry, Seodaemun-gu, Seoul, Korea.
Background: Nonsurgical rhinoplasty (NSR) with dermal fillers has gained popularity because of its immediate and visible results, minimal downtime, and long-lasting effects. However, complications such as filler migration can lead to the development of the "Avatar nose," a condition where the nose appears unnaturally wide and bulbous in the nasion area, disrupting facial harmony. This phenomenon is often exacerbated by the presence of a taut nasofrontal ligament, which tethers the periosteum to the dermal layer and influences nasal contour.

The LMF's formation mechanism remains underexplored due to intricate relationships between musculature and subcutaneous structures. This study aimed to clarify the three-dimensional structures of the LMF using micro-computed tomography and histology.
