When the cuff of the correctly positioned mask is inflated, the thyroid, arytenoid and cricoid cartilages move anteriorly, resulting in bulging of the tissues that overlie the larynx (19).
Additional work is needed to clarify the rotational dynamics of the arytenoid cartilage and cricoarytenoid joint and to develop techniques with abilities to measure movements in this region objectively.
Postoperative examination revealed that the patient had a subluxation of arytenoid. The patient was continually followed by otorhinolaryngology doctors postoperatively.
proposed this procedure in 1984.[2] Endoscopic laser surgery had commonly been used but could result in the formation of granulation tissue leading to renarrowing of the airway or excessive enlargement of the glottic lumen which was irreversible.[3] Most of the laser surgery actually ablated partial arytenoid cartilage, large proportion of vocal ligament, and the thyroarytenoid (TA) muscle to achieve enlargement of the glottic lumen.[3],[4],[5] The cricoarytenoid joint (CAJ) and CAJ fixation (CAJF) were often developed after the first session of laser surgery.
