A cystic lesion above the right
medial canthus for the past 3 years.
CT scan showing a
well-circumscribed lesion arising from the ethmoidal sinus.
Another CT scan view of the lesion.
A straight line was marked over the
lesion before the skin was infiltrated with lignocaine and
adrenaline to aid haemostasis during the operation.
The skin and the periosteum were
incised to expose the ethmoidal mucosa.
The cystic content was aspirated
(15ml of mucous was removed) before proceeding with the operation to
avoid
spilling the content into the
orbital tissue which can cause inflammatory response.
The mucosa was opened and some
mucous could be seen.
4/0 silk was used to exposed the
ethmoidal mucosa and the mucous was removed via irrigation and
suction.
The ethmoidal mucosa was then
dissected from the surrounding tissue.
The ethmoidal bone was removed
using a Kerrison ronguer.
The thin ethmoidal bone could be
easily removed.
A rhinostomy was created by making
a vertical cut using a scalpel. The picture showed that an
instrument
was passed through the nose to
ensure that the rhinostomy was patent.
Mattress sutures were used to
closed the skin.
Appearance of the face at one week
post-operative.
