To the Editor.—With regard to the article entitled "Transconioscopy in Laryngeal Carcinoma" which appeared in the July 1970, issue of Archives of Otolaryngology, Dr. Sorensen indeed presented a very sound argument for the value of retrograde telescopic inspection of the subglottic larynx. The illustrations are especially impressive. I am, however, concerned about the passage of the telescope through the cricothyroid membrane. Our studies have shown that the very subglottic tumors of which he is afraid may indeed invade this area beneath the mucosa. Sorensen does not make any comment about the possibility of this leading to stomal recurrence nor does he specifically state the skin through which his incision is made is excised with the larynx. I would like to suggest that the same view might be obtained from the somewhat lower perspective using the technique originally described by Tucker, Sr.,1 in 1952 which was the use of
