Abstract
The patients were divided in this study into two main groups:
- In the first group (fifteen patients), the periorbital reconstruction
was done using postauricular full-thickness graft.
- In the second group (fifteen patients), the periorbital reconstruction
was done using different types of flaps according to the site of the
lesion.
In this study we choose the excision of basal cell carcinoma with
predetermined margins using postoperative vertical sections taken from
formalin-fixed, paraffin-embedded tissue and immediate reconstruction
was done.
Surgical excision was done with safety margin about 3 mm. except
in two patients with recurrent rodent ulcers and one patient with large
rodent ulcer, the safety margins were about 5 mm. and in all patients
the margins were free of the tumour( 96.6 % ) except in one patient
( 3.3 % ) with the upper eyelid rodent ulcer the inferior margin was
not free of the tumour and no recurrence occur within one year at least
in all patients however much more patients and more prolonged
periods of follow up are required.
Reconstruction of any periorbital defect depends on its size, position,
the state of the surrounding tissues and also the age of the patient.
Periorbital reconstruction of partial thickness defects (anterior
lamellar defect) of upper and lower eyelids can be done using a skin graft
especially if the tumour involves more than 50% of the lid and does not
involve the lid margin.

A retroauricular skin provides an excellent match in the lower
eyelid reconstruction.
Reconstruction of lateral canthal defects using full thickness skin
grafts can be done when the bed is suitable and well vascularised with the
disadvantage that the skin graft that initially looked good may actually
contract and fold and so in the postoperative care.
Reconstruction of medial canthal defects using full thickness skin
grafts can be done also when the bed is suitable and well vascularised
with the disadvantage that the skin graft that initially looked good may
become elevated above the level of the surrounding skin but later on with
the use of silicon patches, the grafts may become not elevated and
became aesthetically good with good colour matching with the
surroundings.
Tissue flaps allow more rapid restoration of eyelid function than
grafts, because their donor site vasculature remains partially intact
.
They are generally thicker than grafts and so may serve to fill a deep
defect, which might not otherwise be adequately covered with a free graft
but this is a disadvantage in inner canthus reconstruction.
