This study evaluated the surgical results of the anteromedial approach for treatment of orbital lesions in 16 patients. Pre- and postoperatively, all patients underwent a complete physical examination focusing on the head and neck area including a thorough ophthalmologic evaluation, computerized tomography, and magnetic resonance imaging. The surgical approach was limited to a medial orbitotomy in five patients; the remaining 11 patients underwent a medial orbitotomy combined with an external sphenoethmoidectomy. The tumor was removed completely without damaging the intraorbital neurovascular structures in all but one patient whose recurrent clival chordoma extended beyond the limits of an extracranial approach. Fibro-osseous lesions, cavernous hemangiomas, and dermoid cysts were the most common pathologies. The follow-up ranged from 18 to 48 months, and no patient has shown evidence of a recurrence. One patient with a clival chordoma received radiation therapy. The lateral nasal skin incision healed with acceptable cosmetic results. The anteromedial approach to the orbit provides a wider working space and direct exposure while protecting neurovascular structures.

Anatomical-Based Filler Injection Techniques: Anteromedial, Buccal, and Lateral Cheek Hollow.
Aesthetic Plast 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, 50-1 Yonsei-ro, Seodaemun-gu, Seoul, 03722, Korea.
Background: Hollowness in the anteromedial, buccal, and lateral cheek regions is a common concern in aesthetic medicine, often resulting from age-related volume loss and structural changes. Advanced filler injection techniques that incorporate a thorough understanding of facial anatomy are critical for achieving optimal and safe outcomes.
Objective: To review and detail anatomically guided filler injection techniques for addressing hollowness in specific cheek regions, considering facial anatomy, ethnic variations, and patient-specific aesthetic goals.
Surgical Treatment of Coronoid Fracture With Elbow Varus Posteromedial Rotatory Instability: An Instructional Review.

Varus posteromedial rotatory instability (VPMRI) of the elbow is one of the complex elbow instability. The primary sites of injury encompass fractures of the anteromedial coronoid process and injuries to the lateral collateral ligament of the elbow. Some patients may present with involvement of the medial collateral ligament of the elbow.

The today well accepted intrapelvic approach for acetabular and pelvic ring injury fixation was first described by Hirvensalo and Lindahl in 1993 followed by a more detailed description by Cole and Bolhofner in 1994. Compared to the well-known ilioinguinal approach, described by Letournel, this approach allows an intrapelvic view to the medial acetabulum, while using the ilioinguinal approach a more superior, extrapelvic view, is dissected to the area of the acetabulum. Several names have been used to describe the new intrapelvic approach with increasing usage, mainly ilio-anterior approach, extended Pfannenstiel approach, Stoppa-approach, Rives-Stoppa approach, modified Stoppa approach and recently anterior intrapelvic approach.

Introduction: The combination of hyaluronic acid (HA) fillers and polydioxanone (PDO) thread lifting is gaining popularity for mid-face rejuvenation, especially among the Asian population. Despite the common use of these techniques, there is a paucity of long-term studies assessing their combined efficacy and safety. This study aims to evaluate the efficacy and safety of combined HA filler and PDO thread treatment for mid-face rejuvenation over a 24-month period in a Korean population.

Background: The terrible triad injury involves an ulnohumeral dislocation, radial head fracture, and coronoid process fracture. According to traditional teaching, these injuries are strongly associated with anterolateral coronoid tip fractures and can be addressed via a lateral approach to the elbow. However, recent small clinical series suggest that some terrible triad injuries have larger coronoid fractures involving the anteromedial facet.
