The eardrum and the middle ear structures are saved, which allows for better hearing than is possible after a radical operation.
During a mastoidectomy, the mastoid air cells located in the mastoid bone are removed. These air cells are typically removed to treat chronic ear infections or other diseases that affect the mastoid bone which houses these cells.
No, onions are not an example of plants with modified roots. Onions have a bulb which is a modified stem, not modified roots. Examples of plants with modified roots include carrot and radish.
Radical neck dissection should not be used when less invasive procedures can achieve the same therapeutic goals, such as modified radical neck dissection or selective neck dissection. It should also be avoided in cases where the risks of surgery outweigh the potential benefits, such as in patients with advanced age or significant comorbidities. Additionally, it may not be appropriate in cases where the patient's quality of life would be significantly compromised by the extensive removal of neck structures.
An example of a modified angiosperm is the Venus flytrap. This plant has evolved specialized modified leaves that can snap shut when triggered by prey, allowing the plant to capture and digest insects for nutrients.
Proteins are modified after they are made in the endoplasmic reticulum and Golgi apparatus within the cell.
The outcome of a mastoidectomy is a clean, healthy ear without infection. However, both a modified radical and a radical mastoidectomy usually result in less than normal hearing.
The eardrum and most middle ear structures are removed, but the innermost small bone (the stapes) is left behind so that a hearing aid can be used later to offset the hearing loss.
A modified radical is a total mastectomy with axillary lymph node dissection, but with preservation of the pectoral muscles.
Mastoidectomy is the medical term meaning surgical removal of the mastoid.

A modified radical mastectomy leaves a woman with a more normal chest shape than the older radical mastectomy procedure, and a scar that is not visible in most clothing.
Modified Radical Mastectomy
A mastoidectomy is performed with the patient fully asleep under general anesthesia

Surgery that removes breast tissue, nipple, an ellipse of skin, and some axillary or underarm lymph nodes, but leaves the chest muscle intact, usually is called a modified radical mastectomy.
