Article Abstract

Aging is associated with volume loss in the temporal fat pad and lateral cheek fat, leading to sunken temples and increased facial sagging. This study explores the efficacy of a polycaprolactone (PCL)-based filler (Lafullen, Samyang, Seoul, Korea) in restoring volume and providing a lifting effect to the lateral face. Four cases were treated with 3 cc of diluted Lafullen (1 cc Lafullen+2 cc normal saline) per side, injected into the interfacial layer (superficial musculoaponeurotic system and superficial temporal fascias). Ultrasound imaging and schematic diagrams were used to guide and assess the injections. Results demonstrated significant improvement in facial volume and contour, with a visible lifting effect. This study highlights the potential of PCL-based fillers in addressing age-related volume loss in the lateral face.

Adenomatoid odontogenic tumor (AOT) is a benign, well-encapsulated odontogenic lesion that typically presents as a slow-growing, asymptomatic mass. Surgical enucleation or curettage remains the treatment of choice due to the tumor's non-invasive nature and well-defined borders, which facilitate complete removal with minimal risk of recurrence. Interestingly, some studies have suggested that AOTs may occasionally arise within pre-existing dentigerous cysts, indicating a possible developmental relationship between the two entities.

Alar Battens Grafts Versus Lateral Crural Strut Grafts: A Systematic Review of Postoperative Outcomes.

Otolaryngol Head Neck Surg

September 2025

Division of Facial Plastic and Reconstructive Surgery, Department of Otolaryngology, Vanderbilt University Medical Center, Nashville, Tennessee, USA.

Objective: To systematically compare functional outcomes and postoperative cosmetic satisfaction following alar batten graft (ABG) versus lateral crural strut graft (LCSG) placement for patients with nasal valve incompetence.

Data Sources: Pubmed and Embase searches (1995-2025) with terms for nasal obstruction, LCSG, ABG, and functional/cosmetic outcomes.

Review Methods: Relevant studies with documented preoperative nasal valve incompetence, confirmed surgical intervention with either ABG or LCSG, and their associated postoperative outcomes were identified.

Introduction: Complex soft tissue injuries in the facial area can arise from various causes. Surgeons face significant challenges when reconstructing these injuries, as they must select appropriate materials based on texture and color, while also considering their composition and properties. The anterolateral thigh (ALT) flap has emerged as a versatile option in clinical reconstructive surgery, offering many advantages over other free flaps.

Purpose: This study investigated how different data collection methods affect final restoration design and dynamic occlusal morphology.

Materials And Methods: Digital systems allow intraoral recording of functional occlusal paths through the digitally recorded functionally generated pathway (DRFGP) technique, using intraoral scanners and optical jaw tracking. Two substudies were conducted.
