In his article, "Surgical Decompression of the Recurrent Laryngeal Nerve in Idiopathic Unilateral Vocal Cord Paresis" (Ann. Otol. 70:451-462, 1961), J. H. Ogura has made a study from the anatomical point of view of those sites in the course of the recurrent nerve which may be predisposed to "physiological compression," and so to blocking of the nerve. He has arrived at an interesting and—as everything seems to indicate—a very fruitful conclusion, i.e., that the region of the cricothyroid articulation is one of the zones in which the recurrent nerve may be exposed to compression of this nature. In particular, the anterior division of this nerve, running in a region between rigid structures, is especially exposed to blockade.
In 4 selected cases of paresis of the recurrent nerve, Ogura performed a subperichondral resection of the inferior cornu of the thyroid cartilage. A rapid restitution of nerve function ensued in 2 cases,
