**Question:** Main treatment of congenital laryngeal stridor is:

A. Surgery
B. Medication
C. Tracheostomy
D. Voice therapy

**Core Concept:** Congenital laryngeal stridor refers to a narrowing or obstruction in the larynx that occurs at birth or shortly after. This condition is often caused by anatomical abnormalities, such as a cyst, polyp, or stenosis. Symptoms include stridor, difficulty breathing, and, in severe cases, respiratory distress.

**Why the Correct Answer is Right:**

The correct answer is **A. Surgery**. Surgery is essential in the management of congenital laryngeal stridor, as medication (option B) and voice therapy (option D) would not effectively address the underlying structural abnormalities causing the obstruction. Tracheostomy (option C) may be needed in life-threatening situations, but it is not the primary treatment modality.

**Why Each Wrong Option is Incorrect:**

Option B, medication, is incorrect because congenital laryngeal stridor is primarily caused by anatomical abnormalities. Medication alone would not resolve these issues and might even exacerbate the condition by suppressing symptoms without addressing the root cause.

Option C, tracheostomy, is sometimes necessary in severe cases to secure the airway and prevent respiratory compromise. However, it is not the primary treatment approach for congenital laryngeal stridor.

Option D, voice therapy, is inappropriate because it is aimed at improving vocal quality or voice modulation and would not address the structural abnormalities causing the laryngeal obstruction.

**Clinical Pearl:**

In cases of congenital laryngeal stridor, it is crucial to differentiate between the treatment options based on the severity of symptoms and the underlying cause of the obstruction. In most cases, surgery is necessary to relieve the obstruction and improve breathing. Severe cases may require additional interventions like tracheostomy, but surgery remains the primary treatment approach.
