INTRODUCTION
 ORBITAL FLOOR FRACTURES PRESENT
WITH SIGNIFICANT PROBLEMSWHICH
REQUIRE PROPER ATTENTIONAND
MANAGEMENT.
 THEREAREVARIOUS MODES OF
MANAGEMENTWITHTHEIR OWN
ADVANTAGESAND LIMITATIONS

CLINICAL FEATURES
 EYELID EDEMA
 CIRCUMORBITAL ECCHYMOSIS
 SUBCONJUNCTIVAL
HEMORRHAGE
 ALTERATION OFVISUAL AXIS
 PARESTHESIA
 DIPLOPIA
 ENOPTHALMOS
 RESTRICTION OF OCULAR
MOVEMENT
 EPISTAXIS

TREATMENT
 MEDICALTHERAPY
 SURGERY
1) conventional surgery
2) endoscopy

Access to orbital
floor# :
 Lateral & medial eyebrow
 Crows feet , existing laceration
 Subciliary or blepheroplasty
 Infraorbital , medial canthal
 Transconjunctival, bicoronal
 Transnasal , antral , buccal sulcus

DISADVANTAGES OF
CONVENTIONAL SURGERY:
 Post operative lid malposition
 Lid shortening
 Entropion
 Ectropion
 Limited visibility of posterior orbit

NEED FOR ENDOSCOPE
 POORVISUALISATION OF POSTERIOR
EDGE OF FRACTURE INVOLVING
POSTERIOR PORTION OF FLOOR.
 INABILITYTO SEETHE CONDITION OFTHE
HERNIATEDTISSUE BEFORE REDUCTION
 HELPSTO CONFIRMTHATALLTHE SOFT
TISSUES HAVE BEEN ELEVATED FROMTHE
FRACTURE SITE.

ENDOSCOPE:
 An instrument used to examine
the interior of a hollow organ
or cavity of the body.
 Unlike other medical imaging
devices endoscopes can be
directly inserted in to an organ.
 Can be used succesfully in
various fields of medicine both
as diagnostic tool or for
treatment.

HISTORY
 Philip Bozzini in 1806 -developed first
endoscope.
 William beaumont in 1822-first introduced
endoscope in to human body.
 Karl storz in 1945-started producing
endoscopes to ENT surgeons.

PARTS:
 A rigid or flexible tube
 A light delivery system to illuminate the
organ or object under inspection
 A lens system transmitting image to the
viewer from the fiberscope
 An additional channel to allow entry of
medical instruments or to manipulate

INDICATIONS:
 Patients with
1)Trap door fracture
2) Medial blow out fractures
3) Lateral blow out fractures
NOTE: Fractures extending lateral to
infraorbital nerve or involving lamina
papyracea are difficult to repair
endoscopically.

ENDOSCOPIC APPROACHES
 TRANS NASAL
 TRANSANTRAL
 INTRA ORAL

ADVANTAGES:
 Improved visualisation
 Anatomic fracture repair
 No risk of post operative eyelid complications
 Good clinical results
 Increased illumination
 Video projection for rest of the surgical
team&documentation
 Precise and complete reduction of herniated soft tissues
 Correct implant placement

DISADVANTAGES:
 PRESENCE OF ORBITAL FAT INTERFERES
WITH INTRAORBITAL USE OF ENDOSCOPE
 TECHNIQUE SENSITIVE
 TRAINED PERSONNEL REQUIRED
 NOT ECONOMICAL
 CAN BE USED IN SOME PARTICULARS
CASES ONLY.
 NEED OF SURGERY IN CASE OF FAILURE.

COMPLICATIONS:
 INFRAORBITAL PARESTHESIA
 POST OPERATIVE SINUSITIS
 PERSISTENT DIPLOPIA

CONCLUSION:
 THE REPAIR OF ORBITAL FLOOR FRACTURE
IS PEREFORMED SUCCESSFULLY USING
ENDOSCOPES IN MANY CENTERS.
 IT ISTECHNICALLY DEMANDINGAND
REQUIREAN EXPERTISE IN USING
ENDOSCOPE.
 IT APPEARSA PROMISING NEW
TECHNIQUE FOR ISOLATEDTRAP DOOR
AND MEDIAL FLOOR FRACTURES.
