OBJECTIVE: This study aimed to describe a graduated approach for effective transoral mobilization of cricoarytenoid joint ankylosis (CJA) in the context of the Bogdasarian system of classifying posterior glottic web-based stenosis (PGWS).
STUDY DESIGN: This is a retrospective cohort study through data from medical records and operative notes. A consecutive series of 23 patients who underwent reconstructive transoral laser microsurgery for PGWS with a significant degree of CJA (Bogdasarian grade III-IV) was included in the study.
METHODS: Techniques necessary to remobilize their cricoarytenoid joints were reviewed in the context of the extent of scar tissue found.
RESULTS: Arytenoids with CJA were successfully mobilized by resection of the fused portion of the cricoid and arytenoid cartilages achieving respiratory improvements as well as decannulation of tracheostomy-dependent patients. The majority (83%) of patient's voices improved. All patients tolerated a full diet after the procedures. Cases with Bogdasarian grade III PGWS with minor unilateral fixation should be classified as IIIa. If the fixation is severe, the case should be classified as a grade IIIb. Grade IVa would indicate that both sides were mildly to moderately ankylosed, and grade IVb involves ankylosis of both joints with subtotal or complete fusion of at least one; it presents the greatest surgical challenge.
CONCLUSION: We provided effective transoral techniques for the re-mobilization of cricoarytenoid joint, along with a classification of CJA that aims to standardize the severity of disease in the context of the existing and widely accepted Bogdasarian scale.
