Final answer:
The term not spelled correctly is 'otomicosis'.
Step-by-step explanation:
The term 'otomicosis' is not spelled correctly. The correct spelling is 'otomycosis' which is a fungal infection of the ear. The other terms in the list are spelled correctly: salpingotomy (a surgical procedure to open the fallopian tube), labyrinthectomy (a surgical removal of the inner ear labyrinth), and tympanorrhexis (a rupture or tear in the eardrum). It is important to double-check spellings to ensure accuracy and clarity in written communication.
