A 25 year old male comes with a complaint of throbbing pain in the upper part of the cheek or entire side of face, heavy feeling in the face, which exacerbates on bending down and with associated pyrexia. The most probable diagnosis is
## **Core Concept**
The symptoms described point towards an infectious or inflammatory condition affecting the facial region, likely involving the sinuses given the location of the pain and associated symptoms. The condition described needs to account for throbbing pain in the upper cheek or entire side of the face, a heavy feeling in the face, exacerbation of pain on bending down, and pyrexia (fever).
## **Why the Correct Answer is Right**
The symptoms of throbbing pain in the upper part of the cheek or entire side of the face, a heavy feeling in the face, exacerbation of pain on bending down, and associated pyrexia are highly suggestive of **acute maxillary sinusitis**. This condition occurs when the maxillary sinuses, which are located in the cheekbones, become inflamed or infected. The pain can be due to the inflammation of the sinus mucosa and the accumulation of pus within the sinus cavity. Bending down increases the pressure within the sinuses, exacerbating the pain. Pyrexia is a common accompaniment due to the infectious nature of the condition.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is not provided, but typically, conditions not related to sinusitis, such as dental problems, temporomandibular joint disorders, or migraines, do not fully explain the combination of symptoms described, especially the exacerbation with bending down and the presence of pyrexia.
- **Option B:** Similarly, without the specific details of option B, any condition not directly related to sinusitis or not fully explaining the symptom complex can be considered incorrect.
- **Option D:** Assuming option D suggests another diagnosis such as otitis media, pharyngitis, or another form of facial pain not related to sinusitis, these conditions would not fully account for the specific set of symptoms described.
## **Clinical Pearl / High-Yield Fact**
A key clinical pearl in diagnosing sinusitis is the presence of **"double sickening"** - a worsening of symptoms followed by a brief period of improvement, and then a further worsening. Additionally, the **"sinus screen"** or specific diagnostic criteria can help, but the hallmark is often the characteristic pain and its exacerbating factors, along with nasal congestion and discharge.
## **Correct Answer:** . Acute Maxillary Sinusitis
