What happens when a cyst keeps growing… and growing? This skull shows a massive nasolabial cyst—an uncommon, non-cancerous growth that forms in the soft tissue just under the nose. In life, it would have caused facial swelling, nasal obstruction, and discomfort. In death, it left a permanent mark on the bone beneath. In this video, we break down what causes nasolabial cysts, why they sometimes grow to this size, and how they affect the surrounding anatomy. | The Bone Museum
