Abstract
Objectives: To stratify the severity of cricoarytenoid joint fixation (CAJF) by surgery and understand the role of it played in the bilateral vocal fold immobility (BVFI). The second objective emphasizes on the significance of the preoperative differential diagnosis from neurogenic immobility with medical history and endoscopic findings.
Methods: A retrospective review was conducted of 74 patients between 2005 and 2022. Careful medical history inquiry, and videolaryngoscopy are conducted to recruit the appropriate surgical candidates. All patients underwent arytenoid remobilization (AR) followed by vocal fold medialization with arytenoid adduction (AA) or lateralization with suture lateralization (SL). The severity of CAJF is graded during the operation or inferred based on the period from operation to recurrence.
Result: A total of 18 patients, aged between 18 and 76 years, were analyzed. Among them, 14 cases were classified as the adducted type with ventilation problems, with three presenting with dyspnea, and 11 requiring artificial airways. Additionally, four patients presented with the abducted type, characterized by aphonia. Meanwhile, two additional cases were considered for comparison but were not included in this cohort of 18 subjects due to incorrect diagnosis and inappropriate management. Using AR procedure, the AA procedure offered three aphonia subjects a voiced sound without airway impairment and the SL procedure decannulated 100% (11/11) of the artificial airways and improved the airway patency in 100% (3/3) of the non-tracheostomized subjects despite the severity of CAJF. The severity of joint ankylosis was distributed as follows: In the aphonia group, there were three subjects with grade I, one subject with grade II, and 0 subjects with grade III. In the ventilation group, there was one subject with grade I, seven subjects with grade II, and six subjects with grade III. In contrast, the two cases used for comparison experienced recurrent dyspnea and failed decannulation because the AR procedure was not performed. The follow-up period was averaged in 58 and 14 months at least.
Conclusion: From this experience, it is the accurate preoperative diagnosis instead of the severity of CAJF that determines the successful rate in airway patency and voiced phonation if the AR procedure is utilized. Careful medical history inquiry and videolaryngoscopic examination can correctly differentiate the mechanical from neurogenic origin without the help of EMG. Evidence of level: 4.
