“…In addition, legitimate questions have been raised by Hoffman et al 15,16 as to whether true intra-articular versus peri-articular CAJ injection is of any clinical significance and how, given the relative rarity of rheumatoid arthritis–related CAJ disease, the potential for studying the efficacy of any of these varying injection techniques, whether trans-cricothyroid with or without trans-illumination 15 or via a posterior approach, is limited. 16…”

Objective: This anatomic study considers the feasibility of a posterior endoscopic approach to the cricoarytenoid joint (CAJ) by describing relationships between readily identifiable anatomic landmarks and the posterior CAJ space in cadaver larynges. Study Design: Anatomic study. Methods: Six adult cadaver larynges (2 male, 4 female) were studied. Digital calipers were used for measurements, and Image J software was used for angle calculations. All cricoarytenoid joints were injected with colored gel via a posterior approach using a 27-gauge needle. Results: The average age of the larynges studied was 78.7 ± 10 years. The average posterior CAJ space (pCAJs) length measured 4.95 ± 0.9 mm. The average distance from the superior aspect of the midline cricoid lamina (MCL) to the center of pCAJs and the corniculate cartilage (CC) to the center of the pCAJs were 8.35 ± 1.5 mm and 14.54 ± 1.9 mm, respectively. The average pCAJs angle of declination (AD) from the horizontal plane was 54° ± 6.2°. All 12 cricoarytenoid joints were successfully injected with colored gel via a posterior approach. Conclusions: The posterior CAJ space can be located surgically using readily identifiable anatomic landmarks. An understanding of this posterior CAJ anatomy may allow for more consistent intra-articular injection and support the development of other CAJ procedures for a range of disorders of vocal fold motion or malposition.
