    Specific Issues for Revision fess Surgery

    1. Observe available landmarks both radiographically and

    clinically.

    2. Moving first from anterior to posterior, check each sinus

    for abnormality. 3. Define or create landmarks necessary to operate safely

    on a sinus-by-sinus basis as the surgeon moves

    posteriorly.

    4. The two most important landmarks are the followinga)

    the maxillary antrostomy to define the lamina papyracea

    and sphenoid sinus. b)The sphenoid sinus to define the

    skull base 5. Repair abnormalities of the maxillary, lower ethmoid and

    sphenoid sinus first.

    6. Once skull base landmarks are defined, repair the upper

    ethmoid and frontal sinuses in a posterior-to anterior

    direction, ending with the frontal sinus.

    7. The same safety techniques for primary ESS apply for

    revision ESS.

    8. There is no easy revision surgery.

    9. Revision surgery is a situation where part of or the wholemiddle turbinate may need removal.

    10. Stenting may be necessary.

    Classification of Complications

  • 7/29/2019 ENT questions

    6/24

    The category correctable with treatment consists of

    orbital hematoma (postseptal), loss of vision, diplopia,

    CSF leakage, meningitis, brain abscess, focal brain

    hemorrhage, hemorrhage requiring transfusion,carotidartery injury, and epiphora.

    Permanent major complications are blindness, diplopia,

    central nervous system deficit, and death.

    What is atticotomy?

    Limited portion of the external canal wall is

    sacrificed

    Small attic sac cholesteatoma exteriorized by

    drilling the scutum to the limits of the sac.Defect is reconstructed with bones or cartilage

    graft

    For limited attic cholesteatoma confined tocentral epitympanum

    COBLATOR

    WHAT IS COBLATION

    Coblation is a unique method of rapid and

    controlled removal of tissue at relatively low

    temperatures (typically 40-70C) while

    maintaining the integrity of surrounding tissue orstructures.

    "Coblation" is a synthetic term that means "cold

    "and "removal".

    Using radio frequency in a bipolar mode with a

    conductive solution, such as saline, Coblation

    energizes the ions in the saline to form a small

    plasma field.

    The plasma has enough energy to break the

    tissue's molecular bonds, creating an ablative

    path.

  • 7/29/2019 ENT questions

    12/24

    The plasma's energized particles have sufficient

    energy to break molecular bond within tissue,

    causing tissue to dissolve at relatively low

    temperatures (typically 40C to 70C).

    The result is volumetric removal of target tissue

    with minimal damage surrounding tissue.
