OBJECTIVE: To compare inferomedial wall orbital decompression to balanced medial plus lateral wall orbital decompression in patients with Graves\' orbitopathy in the inactive phase with regard to exophthalmos reduction and the effects on quality of life.
METHODS: Forty-two patients with inactive Graves\' orbitopathy were randomly divided into two groups and submitted to one of two orbital decompression techniques: inferomedial wall orbital decompression or medial plus lateral wall orbital decompression. Preoperative and postoperative assessments included Hertel\'s exophthalmometry and a validated Graves\' orbitopathy quality of life questionnaire. The results of the two groups were compared.
RESULTS: Compared to preoperative measurement, exophthalmos reduction was statistically significant in both groups (p<0.001) but more so in patients undergoing medial plus lateral wall orbital decompression (p=0.010). Neither orbital decompression techniques increased the visual functioning subscale score on the Graves\' orbitopathy quality of life questionnaire (inferomedial wall orbital decompression p=0.362 and medial plus lateral wall orbital decompression p=0.727), but a statistically significant difference was observed in the score of the appearance subscale in patients submitted to medial plus lateral wall orbital decompression (p=0.006).
CONCLUSIONS: Inferomedial wall orbital decompression is a good alternative for patients who do not require large exophthalmos reduction. However, medial plus lateral wall orbital decompression offers greater exophthalmos reduction and greater improvement in appearance (higher Graves\' orbitopathy quality of life questionnaire scores), making it a suitable option for esthetic-functional rehabilitation.

Crouzon syndrome, distinguished by a classic trio of an atypical skull structure, distinctive facial features, and protruding eyes, ranks among the most prevalent types of craniofacial dysostosis. Therefore, patients presenting with dental abnormalities are under-reported in medical literature despite the developmental neurological defects. We report a rare case of Crouzon syndrome in a four-year-old girl who had forward displacement of the lower jaw, bulging eyes, undeveloped upper jaw, and dental abnormalities. She was evaluated with cranial computed tomography with three-dimensional reconstruction; genetic studies confirmed the findings.

Graves-Basedow\'s disease (GBD) is an autoimmune pathology that affects the thyroid and is characterized by the presence of goiter, hyperthyroidism, ophthalmopathy, and dermopathy. Graves-Basedow ophthalmopathy (GBO) is a set of inflammatory and infiltrative alterations of the orbital tissue that affects 40-90% of subjects suffering from GBD. Our study aims to investigate the differences in the clinical outcomes of patients treated with two different techniques: the classic open and the more modern endoscopic. A retrospective clinical study was carried out from the year 2011 until the year 2020 to evaluate the clinical outcomes of two different surgical techniques for the treatment of GBO. Eighteen patients were given surgical indications, 12 males and 6 females aged between 37 and 69 years (average age 48.5 years), for a total of 36 orbits. From the year 2011 to the year 2014, all patients were treated with the open orbital decompression technique; from 2015 onwards, patients were subjected to orbital decompression with the endoscopic transnasal approach. Pre- and postoperative ophthalmometry, reduction of proptosis, and reduction of oculo-orbital index were compared for the two techniques. As evidenced by the statistical analysis carried out on the sample before and after surgical treatment, there is a statistically significant difference between ophthalmometry and the Oculo-Orbital Index (IOO) values; this indicates that surgical orbital decompression with two walls (floor and medial wall) is effective in reducing exophthalmos. The positive result is also confirmed by the reduction of proptosis, measured in millimeters, averaging 1.7 mm. In the analysis of data relating to the two different patient groups, treated respectively with endoscopic orbital decompression (Technique 1) and classical open orbital decompression (Technique 2), the results obtained show that there is no statistically significant difference between the results of the two techniques. Therefore, the choice of surgical approach is at the discretion of the surgeon. It is our opinion that orbital decompression with the endoscopic transnasal technique should be an absolute indication in all patients who have clinical and radiographic signs of involvement of the optic nerve at the orbital apex (crowded apex syndrome) thanks to the ability of this technique to add and decompress the optical channel at the apex. For all other patients with GBO, the endoscopic technique of orbital decompression can be indicated as a first-line surgical approach considering the absence of skin scars and the best aesthetic results.

BACKGROUND: Lacrimal gland adenoma is a benign tumour of the lacrimal gland mostly involving the orbital part of the gland and composed of epithelial and myoepithelial components. It involves the third and fourth decade of life as a gradual painless enlargement of the lacrimal gland.
METHODS: This is a case report of a 30-year-old female presenting with the forward bulging of the right eye causing the eye to be displaced medio-inferiorly over the course of one year. After careful clinical examination and MRI, a clinical diagnosis of lacrimal gland adenoma was established and was planned for right lateral orbitotomy (without marginotomy) via eyelid crease incision and transcutaneous-transseptal approach with complete excision of the tumour under general anaesthesia.
METHODS: This case was presented to the out patient department with mild painful non-axial proptosis of the right eye. After clinical examination, her MRI report showed a well-defined altered signal intensity enhancing lesion on the extraconal compartment of the right orbit in the antero-supero-lateral aspect. After complete surgical removal of the mass, it was sent for histopathological analysis and it confirmed it as a pleomorphic adenoma. The patient has been following up every 6 months for 2 years and is asymptomatic.
CONCLUSIONS: Being the most prevalent lacrimal gland tumour, pleomorphic adenoma affects the unilateral lacrimal gland causing non-axial proptosis. Complete removal of mass has an excellent prognosis with complete resolution of symptoms.

This study aimed to investigate the effect of orbital wall decompression surgery and reduction of proptosis on the choroidal vascularity index (CVI) and subfoveal choroidal thickness (SFCT) in patients with thyroid eye disease (TED). Fifty-one eyes from 38 patients with controlled TED and proptosis were enrolled in this study. The majority of the patients (50.9%) had a clinical activity score (CAS) of zero, and none had a CAS greater than 2. The patients underwent a complete baseline ophthalmologic examination, and their choroidal profile alterations were monitored using enhanced depth imaging optical coherence tomography (EDI-OCT) before and during the three months after surgery. Changes in SFCT, luminance area (LA), total choroidal area (TCA), and the choroidal vascularity index (CVI) were measured as the ratio of LA to TCA in EDI-OCT images. The participants had an average age of 46.47 years, and 22 were female (57.9%). The SFCT of the patients exhibited a significant reduction over the follow-up period, decreasing from 388 ± 103 to 355 ± 95 µm in the first month (p < 0.001) and further decreasing to 342 ± 109 µm by the third month compared to baseline (p < 0.001). The CVI exhibited a drop from 0.685 ± 0.037 at baseline to 0.682 ± 0.035 and 0.675 ± 0.030 at 1 and 3 months post-surgery, respectively. However, these changes were not statistically significant, indicating comparable decreases in both LA and TCA. There was a significant correlation between improved proptosis and reduction in SFCT (p < 0.001) but not with CVI (p = 0.171). In conclusion, during the three months of follow-up following orbital wall decompression, CVI did not change, while SFCT reduced significantly. Additionally, SFCT was significantly correlated with proptosis reduction, whereas CVI was not.

A patient in his 20s presented with a change in the appearance of his left eye with evidence of relative afferent pupillary defect. Imaging revealed a giant frontoethmoidal osteoma, a benign sinonasal tumour, invading three-quarters of the orbit. Multidisciplinary discussion involving opthalmology, maxillofacial surgery, neurosurgery and otolaryngology resulted in the decision to attempt entirely endoscopic excision of this lesion, which was performed with successful outcomes. This case demonstrates how a sinonasal osteoma should be considered in the differential diagnosis for a patient presenting with proptosis or other eye signs suggestive of compression of the orbital compartment. This case report and literature review highlights the possibility of managing giant sinonasal osteomas with orbital extension through a completely endoscopic approach.

Theodoros Aretaios (1829-1893), having pursued advanced studies at home and abroad and possessing a wide range of competences and interests, was among the first Greek physicians to produce educational treatises for both students and doctors of medicine. Among these is his medical treatise Surgery which deals with thyroid operations and goiter symptoms as well as post-operative lesions which included a record of his extensive experience, learned recommendations, deep insights, and advanced techniques. In this medical archive, which is preserved in the National Library of Greece, there is, for example, the physician\'s vivid description of a thyroidectomy that he performed which illustrates his expertise as a surgeon as well as the surgical knowledge of his times. Aretaios was not the first to perform this operation in Greece: he was, however, the first to document it, which he did for the benefit of his fellow Greeks and of surgeons worldwide.
