Impacts of Chin Surgery on Airway Physiology and Anatomy

This chapter discusses the profound implications of chin surgery, specifically genioplasty, on airway physiology and anatomy. It begins with an exploration of the Posterior Airway Space (PAS) and its critical dimensions influenced by the positioning of the soft palate, tongue, and mandible. The text highlights the dual-purpose nature of genioplasty, which not only serves aesthetic desires but also significantly impacts respiratory efficiency by enhancing the PAS. Through a detailed examination of muscle attachments and their anatomical considerations, the authors argue for a surgical approach that balances aesthetic improvements with functional benefits. The discussion also encapsulates the necessity for personalized surgical planning to optimize outcomes, emphasizing the interconnectedness of facial anatomical changes with airway dimensions and functionality.
