Optimizing Esthetic Outcomes and Bone Stability: Chin Advancement Through Inverted V Osteotomy.

Traditional horizontal osteotomies for small and short chins often yield suboptimal results due to limited bone advancement, resulting in deep labiomental folds and heightened bone resorption risks. This study investigates the effectiveness of an innovative inverted V-shaped osteotomy technique in enhancing esthetic outcomes for patients with such chin concerns. Thirty-eight patients who underwent inverted V-shaped osteotomy for recessed chins between January 2018 and June 2022 were included. Excluding cases involving simultaneous mandibular contouring surgery, patients were followed up for a median duration of 1.2±0.5 years. Preoperation and postoperation soft tissue pogonion (Pg') and labiomental fold depth (LMF) changes were measured. IBM SPSS (version 27.0) was used for statistical analysis, with significance defined as P <0.05. Patient satisfaction was assessed using a visual analog scale. Successful advancement genioplasty was performed on all patients without any severe complications. The average change in soft tissue pogonion (Pg') measured 6.2 (1.9) mm, and the mean alteration in labiomental depth was 0.42 (0.4) mm. The procedure achieved a bone to soft tissue movement ratio of 1:0.96. Patient satisfaction was notably high, with a mean VAS score of 8.7. An inverted V-shaped osteotomy enables greater bone advancement for small and short chins, leading to improved esthetic outcomes and offering a mechanically advantageous condition for bone segments.

Genetic content in Korean nursing textbooks.

Due to the significant developments in genetic health services that have occurred, nurses now must strive to incorporate cutting-edge information from this fast-evolving field into their day-to-day practice. This study examined the amount and the content of genetics education in Korean nursing textbooks. We analyzed 165 textbooks that were published by four companies between 2005 and 2009. Eighty percent contained some information on genetics; however, the content was limited to bioscience, the latest information on common diseases, and nursing interventions in genetics. There was an average of six pages of genetics content in the seven specialized textbooks on nursing that were analyzed. This indicates that many topics on genetics need to be incorporated into Korean nursing education, especially in light of the recent genetic innovations in all curricular areas of nursing education. We recommend the establishment of strategic perspectives to bridge the content gaps in genetics education in nursing.
