Trotter’s triad includes all of the following Except –
**Core Concept**
Trotter's triad is a classic clinical association of symptoms seen in patients with odontogenic maxillary sinusitis, which is an infection of the maxillary sinus caused by dental pathology. This condition is characterized by a combination of symptoms that occur due to the spread of infection from the teeth to the adjacent sinuses. The underlying pathophysiological process involves the transmission of infection through the mucous membranes and bone to the maxillary sinus.
**Why the Correct Answer is Right**
Trotter's triad includes three main symptoms:
* Severe facial pain, usually in the maxillary region, which is caused by the involvement of the trigeminal nerve (cranial nerve V) and the maxillary nerve (a branch of the trigeminal nerve).
* Conductive hearing loss, which occurs due to the blockage of the auditory tube (Eustachian tube) by the infection, preventing proper drainage of the middle ear.
* Proptosis (bulging of the eye), which is caused by the increased venous pressure in the face resulting from the infection.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not a part of Trotter's triad. While dental pain can be associated with odontogenic maxillary sinusitis, it is not a distinct component of Trotter's triad.
**Option B:** This option is not a part of Trotter's triad. While facial swelling can be associated with various infections, it is not a specific symptom of odontogenic maxillary sinusitis as described in Trotter's triad.
**Option C:** This option is not a part of Trotter's triad. While fever is a common symptom of many infections, it is not a distinct component of Trotter's triad.
**Clinical Pearl / High-Yield Fact**
Trotter's triad is a classic example of a clinical syndrome that highlights the importance of considering the relationship between dental pathology and sinusitis in patients presenting with facial pain and conductive hearing loss.
**Correct Answer: D.**
