Classic approaches include lateral
pharyngotomy or direct suspension microlaryngoscopy.

pharyngotomy for the treatment of small (T1~2) hypopharyngeal squamous cell carcinoma," Clinical and Experimental Otorhinolaryngology, vol.
Other approaches are transmandibular approach, lateral
pharyngotomy approach and suprahyoid approach for large lingual thyroids.
A median
pharyngotomy is created after dissecting off the suprahyoid musculature.
However, submandibular, suprahyoid
pharyngotomy and transhyoid approaches have been used for schwannomas at the tongue base that are deemed difficult to approach transorally.
Depending on site and size of tumor, three types of external approaches are used like Laryngofissure, lateral
pharyngotomy and sub-hyoid
pharyngotomy.
Several other approaches have also been reported to have success including submandibular (11), suprahyoid
pharyngotomy (12), and transhyoid (13) approaches.
(14) However, an open technique can be used if desired--for example, when a total laryngectomy is performed in the standard fashion and the open
pharyngotomy is retracted into the jaws of the stapling device prior to activation.
Several other approaches have also been reported to have success including submandibular 11, suprahyoid
pharyngotomy (20), and transhyoid (21) approaches.
Following preoperative preparation, the lesion was excised via a median
pharyngotomy approach.
Several approaches to excising a schwannoma are available, including direct laryngoscopy with conventional instruments or a C[O.sub.2] laser, the transhyoid approach, the laryngofissure approach, and the lateral
pharyngotomy approach.
