Which diagnosis includes symptoms such as drooling, trismus, and a "hot potato" voice?

The correct diagnosis associated with symptoms such as drooling, trismus, and a "hot potato" voice is a peritonsillar abscess. This condition typically arises as a complication of tonsillitis and is characterized by the accumulation of pus near the tonsils.

The symptom of drooling indicates difficulty swallowing due to pain or obstruction, which is common in a peritonsillar abscess. Trismus, or restricted mouth opening, occurs as a result of muscle spasm and irritation in the surrounding tissues. The "hot potato" voice describes a muffled or husky sound, similar to speaking while holding a hot potato in one's mouth, which reflects the pain and swelling in the oropharyngeal region that makes speaking difficult.

Understanding these symptoms helps in promptly recognizing a peritonsillar abscess, as it can lead to serious complications if not managed effectively. Other conditions listed do not present the same combination of symptoms as clearly as a peritonsillar abscess.
