hello thank you for your question and provided information as well.. based in your question It depends on the anesthesia used by the anesthesiologist, usually for the breasts it is used blockage (epidural) and soft sedation.An oropharyngeal cannula is placed in the same way for greater patient safety.
Thank you for your question. The answer will depend on what time of anesthesia you surgeon will be using. In most cases, general anesthesia is used. Some anesthesiologists will place an LMA (laryngeal mask airway) which sits above your airway, but does not pass your voice box (larynx). In other cases, an endotracheal tube (breathing tube) is placed to secure the airway. Some of these decisions are made based on your underlying medical history. Talk to your surgeon to see what they prefer. Good luck.
