**Title:** Ancient Surgeries: A Look Back at Primitive Medical Practices
**Summary:**
* The video discusses three ancient surgical practices:
1. **Trepanning (c. 6500 BC)**: A skull-opening procedure using rocks, surprisingly showing signs of healing in many cases, with over 1,500 examples found worldwide.
2. **Rhinoplasty (c. 600 BC, India)**: Described by Maharshi Sushruta, involving a skin flap from the cheek or forehead to repair the nose.
3. **Weight Loss Surgery (10th century, Spain)**: A drastic method where a physician stitched a king's (Sancho the Fat) lips together, forcing him to consume nutrients through a straw, resulting in significant weight loss.
* Additionally, two ancient **Cataract Surgery** methods are mentioned:
+ **Couching Method**: Using a sharp object to push the lens out of the way (mostly unsuccessful).
+ **Suction Method (10th century AD)**: Extracting the lens through a large incision and suction (more successful).
**Closing:** The video concludes by acknowledging the primitiveness of these practices and encouraging viewers to appreciate modern medical advancements, while also promoting an educational platform (Brilliant.org) for learning about various subjects, including science and math.
