Anterior cricoid split procedure with transposition of cricoid cartilage segment
1Department of Otorhinolaryngology-Head and Neck Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, South Korea.
Objective:
In order to improve the outcome and to reduce the post-operative care burden following the anterior cricoid split procedure, we modified the procedure to involve splitting only the cricoid cartilage, not the mucosa deep to the cartilage. In addition, we transposed the cricoid cartilage segment after division of the cricoid ring in the midline.
Case Report:
We present the use of our modification in a 19-month-old boy with early-stage subglottic stenosis.
Results:
The technique was performed in one surgical field, and the graft material obtained had the same thickness as the cricoid cartilage. Because there was no intraluminal break, this procedure allowed the patient to avoid the complications of prolonged stenting, and resulted in more rapid extubation.
Conclusion:
The anterior cricoid split procedure with transposition of the cricoid cartilage segment may be a useful treatment option for early-stage subglottic stenosis, with improved outcomes and a reduced post-operative care burden.
