Pediatric Tracheostomy in a 7 year old child Dr. Tamer Ashraf Wafa

Why Pediatric Tracheostomy Exists as a Distinct Procedure

Tracheostomy in children is not simply a scaled-down adult operation 1:30. Pediatric anatomy—shorter trachea, more anterior position, smaller working field—demands different landmarks, different ring selection, and different safety margins 1:30. The procedure creates a surgical airway when prolonged ventilation is needed or when upper airway obstruction cannot be managed by other means. Getting it right the first time matters because the consequences of malposition or loss of the airway in a child are immediate and severe.

The Core Technical Problem

The challenge is creating a stable anterior tracheal opening at the correct level while avoiding injury to surrounding structures in a confined space 0:00 1:30. In a child, the target zone lies between the cricoid cartilage and the suprasternal notch—a limited span 0:00. Within that space: anterior jugular veins, thyroid isthmus, strap muscles, and the trachea itself, which is both smaller in diameter and more mobile than in adults 0:30 1:00. The opening must be large enough to accept the tube but not so large that it destabilizes the tracheal wall 2:25. Bleeding into the airway during the procedure can obstruct ventilation in seconds 2:10.

How the Approach Works

Exposure

The incision is a 2-centimeter transverse cut placed midway between the cricoid and the sternal notch 0:00. This positioning balances access against the risk of creating a stoma too high (risking subglottic stenosis) or too low (risking innominate artery injury in smaller children, though that is not discussed here). After dividing the superficial fascia, the anterior jugular vein may appear; if encountered, it is coagulated and divided 0:30. The deep cervical fascia is then split vertically—not transversely—to follow the natural tissue planes 0:40.

The thyroid isthmus lies directly over the trachea 1:00. Dr. Wafa describes two options: cauterize and divide it, or retract it downward 1:00. Neither is universally preferred; the choice depends on the size of the isthmus and the exposure it affords. Dividing it provides a cleaner field but adds a vascular step. Retracting it is faster but may crowd the operative space.

Ring Selection

Once the pre-tracheal fascia is cleared, the tracheal rings become visible and must be counted 1:30. In children, the third and fourth rings are the target 1:30. Dr. Wafa states this plainly: "In children, the third and fourth rings are the best level" [q1]. This is lower than the second ring sometimes used in adults, reflecting the need to avoid the cricoid and first ring, where stenosis risk is highest 1:30. Counting errors here are unforgiving—too high and you risk subglottic injury; too low and the tube may sit near the carina or against the innominate artery.

Opening the Trachea

Before incising, two non-absorbable stay sutures are placed on either side of the planned opening 1:40. These are not decorative. If the tube is dislodged in the first postoperative days—before a mature tract forms—the stay sutures can be pulled laterally to reopen the stoma and guide reinsertion 1:40. They are left in place and taped to the chest with clear labeling not to remove them 2:53.

The edges of the planned incision are cauterized with bipolar diathermy to reduce bleeding 1:55. The trachea is then incised vertically with a sharp blade 2:05. Suction must run continuously during this step to prevent blood from entering the airway 2:10. Dr. Wafa emphasizes this: "Suction should be continuously applied, to prevent blood from entering the airway" [q2]. Pulling the stay sutures laterally opens the lumen 2:20, and the opening is widened only enough to admit the tube 2:25—"just enough to admit the suitable tube" [q3]. Excessive widening risks cartilage collapse or difficulty achieving a seal 2:25.

The endotracheal tube, which has been maintaining ventilation throughout, is pulled back to the level of the tracheostomy opening 2:30. The tracheostomy tube is then inserted 2:40. Air entry is immediately checked in both lungs 2:40 to confirm position and patency.

Closure and Securing

The wound angles are approximated with absorbable sutures 2:45—not a tight closure, which would risk subcutaneous emphysema, but enough to reduce dead space 2:45. The neck is flexed and the tube is tied securely 2:50. Flexion prevents the tie from loosening with neck extension 2:50. The stay sutures remain external, taped and labeled 2:53.

Where Practice Varies

The handling of the thyroid isthmus is not standardized 1:00. Some surgeons routinely divide it for exposure; others preserve it unless necessary 1:00. The decision often rests on individual anatomy and the surgeon's assessment of the working room.

The question of whether to create a formal tracheal flap (such as a Björk flap) versus a simple vertical incision is not addressed in this discussion. Flap techniques are used in some centers to create a more stable tract, but they are not universal in pediatric practice and carry their own risks of stenosis.

When to Involve Pediatric Otolaryngology or Pediatric Surgery

Tracheostomy in children is not an emergency airway procedure—that role belongs to endotracheal intubation or, in extremis, cricothyrotomy. Tracheostomy is a semi-elective operation performed in the operating room under controlled conditions. Indications include prolonged ventilator dependence, upper airway obstruction that cannot be bypassed by intubation, and need for pulmonary toilet in children with poor secretion clearance.

Referral should occur early in the decision-making process, not when the airway is already in crisis. The surgical team needs time to assess anatomy, plan tube size, and coordinate with anesthesia and intensive care.
