Trotters triad is seen in carcinoma of –
**Core Concept**
Trotter's triad is a classic clinical presentation seen in patients with carcinoma of the maxillary antrum. It consists of three main symptoms: severe facial pain, conductive hearing loss, and diplopia (double vision). This triad is a result of the tumor's invasion into the surrounding structures, including the maxillary sinus, orbit, and temporal bone.
**Why the Correct Answer is Right**
The correct answer is due to the anatomical relationship between the maxillary antrum and the surrounding structures. The maxillary antrum is a paranasal sinus located in the maxillary bone, and its carcinoma can invade the surrounding structures, including the orbit and the temporal bone. This invasion leads to the symptoms of Trotter's triad. The maxillary antrum is also closely related to the middle ear, which is why conductive hearing loss is a common feature of Trotter's triad.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because the symptoms of Trotter's triad are not typically seen in carcinoma of the mandible (lower jaw).
* **Option B:** This option is incorrect because the symptoms of Trotter's triad are not typically seen in carcinoma of the thyroid gland.
* **Option C:** This option is incorrect because the symptoms of Trotter's triad are not typically seen in carcinoma of the esophagus.
**Clinical Pearl / High-Yield Fact**
Trotter's triad is a classic clinical presentation that should prompt further investigation into the possibility of a maxillary antrum carcinoma. Remember the "3 Ps" of Trotter's triad: Pain (facial pain), Perception (hearing loss), and Palsy (diplopia).
**Correct Answer: C. Carcinoma of the maxillary antrum.**
