Which condition would increase the difficulty of performing endotracheal intubation?

• A. Tetralogy of Fallot
• B. Congenital diaphragmatic hernia
• C. DiGeorge's syndrome
• D. Treacher Collins Syndrome

Answer: (D)

Difficult airway management arises when facial and jaw anatomy limits the ability to visualize the vocal cords and pass the endotracheal tube. Treacher Collins Syndrome causes significant craniofacial hypoplasia, including mandibular hypoplasia (micrognathia), limited mouth opening, and sometimes glossoptosis. These changes disrupt the alignment of the oral, pharyngeal, and laryngeal axes and reduce space to maneuver the blade and tube, making direct laryngoscopy and intubation notably harder. While other conditions like congenital heart defects or diaphragmatic hernia can complicate anesthesia overall, they don’t typically create the same inherent airway visualization and access challenges seen with Treacher Collins. Planning for a difficult airway with alternative strategies (such as video-assisted or fiberoptic intubation and rescue airway plans) is especially important in patients with this syndrome.
