Certain embodiments described herein provide a method of performing an otological surgical procedure including surgically accessing a middle ear, injecting a perfluorocarbon liquid into the middle ear, and suctioning the isolated blood from the middle ear without removing the perfluorocarbon liquid. The perfluorocarbon liquid is immiscible with blood for isolating blood in the middle ear from the perfluorocarbon liquid. In certain embodiments, the perfluorocarbon liquid has a specific gravity greater than blood to apply positive pressure to surrounding tissues. In certain embodiments, the method includes suctioning the perfluorocarbon liquid from the middle ear after the isolated blood is removed.

Intratympanic injection of therapeutic agents into the inner ear can be used to treat conditions such as hearing loss. One or more stabilizer devices defining a working channel can be temporarily implanted into the tympanic membrane. Specialized instruments, such as endoscopes, forceps, and injection instruments, can be passed through the working channel of the stabilizer device to access the inner ear, where administration of the therapeutic agent can occur. The stabilizer device is then removed from the tympanic membrane, and the tympanic membrane can heal, typically without the need for suturing.
