Commonest postoperative complication of tonsillectomy is
**Core Concept**
Tonsillectomy is a surgical procedure that involves the removal of the palatine tonsils, which are lymphoid organs located in the oropharynx. The postoperative complications of tonsillectomy can be divided into immediate (less than 24 hours) and delayed (more than 24 hours) complications.
**Why the Correct Answer is Right**
The commonest postoperative complication of tonsillectomy is **postoperative hemorrhage**, also known as bleeding. This occurs due to the transection of the palatine tonsil's blood vessels, which can lead to bleeding from the surgical site. The risk of bleeding is higher in the first 24 hours after surgery, and it can be life-threatening if not promptly managed. The risk factors for postoperative hemorrhage include a history of bleeding disorders, anticoagulant therapy, and previous episodes of postoperative bleeding.
**Why Each Wrong Option is Incorrect**
* **Option A:** **Peritonsillar abscess** is a complication of tonsillitis, not tonsillectomy. It occurs when a collection of pus forms behind the tonsils due to a bacterial infection.
* **Option B:** **Recurrent laryngeal nerve palsy** is a potential complication of thyroid surgery, not tonsillectomy. It occurs when the recurrent laryngeal nerve is damaged during surgery, leading to hoarseness and breathing difficulties.
* **Option C:** **Dysphagia** is a potential complication of many surgical procedures, including tonsillectomy. However, it is not the most common postoperative complication of tonsillectomy.
**Clinical Pearl / High-Yield Fact**
To reduce the risk of postoperative hemorrhage, it is essential to use proper surgical techniques, such as electrocautery, and to administer prophylactic antibiotics. Patients should also be closely monitored for signs of bleeding, such as hematemesis, melena, or hematuria, in the first 24 hours after surgery.
**Correct Answer:** D.
