Submucous resection
This is the process of removing cartilage or bone which is underneath mucosa. Mucosa is the inner lining of the nose. So submucous resection refers to elevating the internal lining of the nose to remove either cartilage or bone. Submucous resection is performed for septoplasty, septal cartilage harvest, as well as some types of turbinate reduction (turbinoplasty).
