Question 1: What is the most common indication of tracheostomy in a child?
- A. Laryngeal diphtheria
- B. Poliomyelitis
- C. Carcinoma of larynx
- D. Vocal cord paralysis (Correct Answer)
Explanation: ***Vocal cord paralysis***
- Among the options listed, **vocal cord paralysis** is the most appropriate answer as it remains a relevant pediatric indication for tracheostomy in current practice.
- **Bilateral vocal cord paralysis** can cause significant airway obstruction requiring tracheostomy, especially in congenital cases or after cardiac surgery.
- Note: In modern pediatric practice, the overall most common indications are **prolonged mechanical ventilation** and **congenital airway anomalies**, but among the specific causes listed here, vocal cord paralysis is the best answer.
*Laryngeal diphtheria*
- While **laryngeal diphtheria** historically was a common cause of pediatric tracheostomy due to pseudomembrane formation causing severe airway obstruction, its incidence has drastically decreased with **widespread immunization programs**.
- In the pre-vaccination era, this was indeed a leading indication, but it is now rare in countries with effective vaccination coverage.
*Poliomyelitis*
- **Poliomyelitis** can affect respiratory muscles leading to ventilatory failure requiring tracheostomy, but with **global eradication efforts and vaccination**, it is now extremely rare.
- This was a significant historical indication but is no longer relevant in most parts of the world.
*Carcinoma of larynx*
- **Laryngeal carcinoma** is predominantly an adult malignancy with peak incidence in the 6th-7th decades, associated with smoking and alcohol use.
- It is **extremely rare in the pediatric population**, making it the least likely indication for tracheostomy in children among all the options listed.
