EYELID RECONSTRUCTION AN OVERVIEW

EYELID RECONSTRUCTION AIMS MAINTAIN FUNCTION & INTEGRITY OF PERIORBITAL STRUCTURES ACHIEVE OPTIMAL COSMESIS

EYELID RECONSTRUCTION GOALS SMOOTH MUCOSA-LIKE INTERNAL LINING STABLE EYELID MARGIN WITH LASHES PROJECTING AWAY FROM THE GLOBE LID RIGIDITY OF THE TARSAL AND CANTHAL AREAS FUNCTIONAL RETRACTORS ADEQUATE CLOSURE FOR PROTECTION AND LUBRICATION ACCEPTABLE COSMESIS

EYELID RECONSTRUCTION ANATOMY EYELID POSITION HALFWAY BETWEEN PUPIL & LIMBUS – NORMAL EXCURSION 16MM CANTHAL POSITION - LATERAL AGAINST GLOBE MEDIAL, SEPARATION BY LACRIMAL CARUNCLE

EYELID ANATOMY LATERAL ANGLE 2-3MM HIGHER THAN THE MEDIAL CANTHAL AREA EYELIDS TWO LAMELLA ANTERIOR - SKIN AND MUSCLE, POSTERIOR - CONJUNCTIVA TARSAL PLATE LID RETRACTORS

EYELID ANATOMY LID MARGIN 2MM THICK ANTERIOR EYELASHES POSTERIOR MEIBOMIAN GLAND ORIFICES GREY LINE SEPERATES TWO AREAS

EYELID ANATOMY PUNCTUM BLOOD SUPPLY INFERIOR TYPICALLY 2MM LATERAL TO SUPERIOR BLOOD SUPPLY MARGINAL ARTERY 3-4MM FROM MARGIN

LACRIMAL SYSTEM LACRIMAL GLAND LACRIMAL DRAINAGE SYSTEM PUNCTA UPPER AND LOWER CANALICULI LACRIMAL SAC AND NASO-LACRIMAL DUCT

PREPARATION ANAESTHESIA – WOUND PREPARATION – GLOBE PROTECTION LUBRICATION CORNEAL PROTECTOR SUTURE PLACEMENT ANAESTHESIA – LOCAL, GENERAL, TOPICAL WOUND PREPARATION – MINIMAL DEBRIDEMENT
