To describe a novel method of reconstruction after orbital exenteration.
Following a lid sparing orbital exenteration for Squamous Cell Carcinoma with
intra-orbital invasion, the socket was filled with a dermis fat graft (DFG). A
buccal mucosal graft was wrapped around a conformer shell with the epithelial
surface inside; this was anchored to the dermis side of the DFG. The edges
of the eyelid skin were closed. After six months the lid skin-anterior mucosal
graft was opened and the edges sutured to form the new lid margins. The clear
shell was exchanged for a custom fit Artificial Eye (AE). The DFG reabsorbed
partially, the mucosal graft had taken well providing good deep fornices. The AE
was well retained in the new socket. At 16 months follow up there are no signs
of tumour recurrences. Cosmesis is good although there is no eyelid or AE
movement as expected. This represents an alternative method, however it is
not possible to monitor for recurrences of the tumour and hence this technique
should not be adopted for neoplasias with known posterior extension. To the
best of our knowledge this is the first time such technique has been applied.

Background: Surgical approaches increasingly used in Graves-Orbitopathy(GO)
induced disfiguring proptosis are two- to three wall decompression utilizing
different techniques with 3-5mm resulting in an average reduction of proptosis.
The aim of our study was to identify the outcomes using a single lateral wall-
Swinging-eyelid (SE) approach to decrease proptosis in GO.
Methods: Medical records of patients, who underwent single lateral SE
decompression from 2009 to June, 2011 were retrospectively reviewed. Surgical
indications were disfiguring proptosis and compressive optic neuropathy.
Reduction of proptosis measured using Naugle-Exophthalmometery, changes
in visual acuity, intraocular pressure (IOP) and complications rate were
evaluated. Non-parametric Wilcoxon signed rank test was used for statistical
analysis.
Results: 40 patients (total of 58 orbits) were identified. The median preoperative
Naugle-Exophthalmometery value was 24mm ([IQR] 23-25mm). A significant
reduction of proptosis (median 3mm, IQR 2.6 to 4.4, p
