A) Dysphagia
B) Hoarseness
C) Dyspnea
D) All of the above

Answer 1

Injury in the posterior triangle by a tumor, stab wound, or surgery may result in Dysphagia, Hoarseness, and Dyspnea.

Step-by-step explanation:

Injury in the posterior triangle by a tumor, stab wound, or surgery may result in All of the above - Dysphagia, Hoarseness, and Dyspnea.

The posterior triangle is a region in the neck that contains important structures such as the brachial plexus, blood vessels, and the cranial nerve XI (accessory nerve). Injury to these structures can have various effects on the body.

For example, if the brachial plexus is affected, it can lead to dysphagia (difficulty swallowing) due to weakened muscles involved in swallowing. Damage to the cranial nerve XI can cause hoarseness because it controls the muscles of the larynx and pharynx. Injury to blood vessels or the phrenic nerve can result in dyspnea (shortness of breath) due to impaired blood flow or compromised respiratory function.
