Explanation

Gentamicin is an aminoglycoside antibiotic that is well-known for its ototoxic effects

Potentially causing damage to the inner ear and leading to hearing loss or balance issues.

The other drugs listed are not typically associated with ototoxicity:

1. Contimycin: This appears to be a less commonly used or less well-known drug; assuming it refers to an antibioticIt is not generally recognized for ototoxicity.
2. Amoxicillin: This is a penicillin-type antibiotic and is not known to be ototoxic.
3. Erythromycin: This is a macrolide antibiotic and, it is not typically ototoxic.
4. Penicillin: This class of antibiotics is not associated with ototoxicity.

Explanation

Explanation

Malignant tumors of the larynx can spread through multiple pathways, including:

1. Lymphatic channel: The most common route of metastasis for laryngeal cancer is the lymphatic system.
2. Nerve: Perineural invasion can occur, although it is less common than lymphatic spread.
3. Blood: Hematogenous spread (through the bloodstream) can occur, leading to distant metastases.
4. Direct spread to distant structures: Laryngeal cancer can directly invade adjacent structures such as the thyroid, esophagus, and neck muscles
