Previously, we introduced a modified lateral approach with a mouth corner incision from the lower lip, that preserves the mental and marginal mandibular nerves.

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.

Article Synopsis
  • Large facial defects have historically been repaired using cervicofacial rotation flaps; this study examines the effectiveness of SMAS island flaps for such reconstructions.
  • A retrospective analysis of 36 patients (predominantly male, average age 69) who had undergone flap surgery between 2009 and 2023 revealed a mean flap advancing distance of 3.8 cm, with a low incidence of ischemia (8%).
  • The results suggest that SMAS island flaps are reliable for large cheek defects, with anterior pedicles being preferable for anterior defects and posterior pedicles for those located in the back.

Exotic companion mammals represent a branch of veterinary medicine with important implications in dentistry. The standard dental nomenclature and the systems of numbering teeth have not been applied in detail in these species and are not very familiar to many veterinarians. Selected species such as lagomorphs and rodents have anatomic and physiologic features that affect terminology and numbering.
