What is a primary use of a fine Rosen needle in otorhinolaryngology?

The fine Rosen needle is specifically designed for delicate surgical procedures in the field of otorhinolaryngology, particularly in operations involving the ear. Its primary use is to fracture the stapes during a stapedectomy. Stapedectomy is a surgical procedure aimed at reducing hearing loss caused by otosclerosis, a condition where the stapes bone becomes immobilized. The fine Rosen needle is favored for this task due to its precision and ability to target the stapes without causing excessive trauma to surrounding structures, ensuring the process is delicate and controlled.

While the Rosen needle may also be seen in other contexts, its specific function in fracturing the stapes makes it particularly well-suited for this application. In contrast, performing suturing, removing polyps, and biopsying tissues typically require different instruments and techniques that may not provide the same level of finesse needed in such a sensitive area as the ear.
