Cricoarytenoid Joint Ankylosis: Classification and Transoral Laser Microsurgical Treatment.

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.

Laser tracheobronchoplasty: a novel technique for the treatment of symptomatic tracheobronchomalacia.

The management of tracheobronchomalacia is a very challenging problem with few treatment options. This study aims to evaluate the outcomes of a novel surgical treatment for membranous tracheobronchomalacia. A consecutive series of patients with tracheobronchomalacia were treated with two to three holmium laser scarring surgeries of the hyperdynamic tracheal and bronchial walls for the purpose of stiffening them through fibrosis. Patients filled out a Dyspnea Index questionnaire before and after treatment. Ten patients were treated for their tracheobronchomalacia with a mean age of 54 years. Symptoms included severe dyspnea, dry cough, recurrent pulmonary infections, and respiratory failure. Fifty percent of patients presented with wheezing refractory to traditional treatment. Tracheobronchomalacia was associated with gastroesophageal reflux disease (n = 8), obstructive sleep apnea (n = 5), and tracheal stenosis (n = 3). Only 50 % of patients presented with morbid obesity. All cases showed significant improvement of their respiratory symptoms with a mean postoperative difference of 22.3 out of a maximum impairment score of 40 (P < 0.01) on the Dyspnea Index. The mean number of procedures was 2.3 per patient with the average laser energy delivered per procedure of 1600 J. Laser tracheobronchoplasty is a safe, easy to adopt, and effective technique for the treatment of membranous tracheobronchomalacia. It presents a simple alternative to the commonly used procedures like endoluminal stenting and open tracheobronchoplasty.
