| Abstract|| |
The orbit can be affected by primary intraconal lesions as well as cavernous hemangiomas. This article illustrates for the first time the retroseptal dissection (RD) route combined to the superior eyelid crease approach (SECA) to treat a symptomatic hemangioma inside the superomedial intraconal space. It also reviews the main studies about the argument. A 42-year-old woman affected by a mild painful proptosis and some accommodation difficulties in her right eye. The magnetic resonance imaging revealed a soft intraconal mass in the superomedial quadrant of the right orbit. The lesion was removed performing a SECA with RD through an incision inside a natural eyelid crease. Disappearance of pain with an improvement of accommodation was reported immediately. During the whole follow-up, the visual acuity, field examinations, and ocular motility did not reveal any impairment. Our approach represents a valid, quick, not technically demanding and mini-invasive method to access the superomedial intraconal space. Finally, it gives excellent functional and cosmetic results.

| Introduction|| |
Cavernous hemangiomas (CHs) are the most common benign vascular tumor of the head and neck. One of the most involved regions is the orbit. Observation is indicated in not growing asymptomatic lesions while surgical treatment is always indicated in symptomatic cases.
In this report, the authors present a symptomatic case of a superomedial intraconal CH, successfully treated by surgical removal through a superior eyelid crease approach (SECA). The novelty is that it has been combined it with a new pathway to reach the superomedial intraconal space: the retroseptal dissection (RD) route [Figure 1]. This case report has been reported in line with the SCARE criteria.

| Case Report|| |
A 42-year-old female was referred to us because of a mild, axial, and painful proptosis in the right eyeball without visual field loss and diplopia. The patient declared only worsening at short distance accommodation in the right eye. The magnetic resonance imaging (MRI) revealed a neoplasm in the right intraconal area, behind the eyeball, dislocating the optical nerve [Figure 2]a and [Figure 2]b. According to the neuroradiologist and our clinical evaluation, the lesion could be a hemangioma. Therefore, considering the location, the anatomic relationships and the sizes, the patient was candidate to remove the tumor through a SECARD.

A natural eyelid crease was chosen [Figure 3]a. A curvilinear incision <3 cm long was made through the skin and orbicularis muscle. Dissection was conducted in a plane between the orbicularis muscle and the orbital septum toward the frontal bone, until the supra-orbital and supra-trochlear nerves were exposed, lateralized, and protected [Figure 3]b. The periosteum was incised over the superior orbital rim [Figure 3]c and elevated to realize a sub-periosteal plane. The trochlea was visualized; the periorbita was entered from above in a retroseptal route, proceeding with blunt dissection through the intraorbital fat until the exposure of the tendon of the underneath superior oblique muscle. Blunt dissection was continued under the tendon toward the posterior pole of the eye, then passing in between the superior and medial rectus muscles, gently retracting them to access the superomedial intraconal space and its content. The lesion was seen as a dark red soft mass [Figure 4]a and released by the surrounding muscles, intermuscular orbital fat and finally by the optic nerve. The tumor was removed en bloc [Figure 4]b without noble structures damage. The procedure was performed in 45 minutes.

No visual impairment, no mydriasis, no ophthalmoplegia or any duction weakness was objectified. The intraorbital throbbing pain as well as the accommodation disturbance disappeared after surgery.
The histopathological examination revealed a CH. After 3 months the MRI demonstrated complete removal of the hemangioma [Figure 5]a and [Figure 5]b; the clinical assessment showed normal ocular motility and with an almost invisible scar hidden by the patient's own skin excess [Figure 6]a and [Figure 6]b.

| Discussion|| |
CHs are congenital low flow vascular malformations. Being slow-growing masses, their most common clinical sign is painless proptosis, without motility disorders or compression of the optic nerve. If the optic nerve is compressed, progressive alterations of vision are possible until blindness. Due to orbital anatomy and its noble structures, before surgery is taken a judicious medical evaluation is needed; therefore, treatment is recommended in symptomatic cases., Surgical treatment is usually definitive, although rare cases of local recurrence are described in literature, perhaps related to incomplete resection. The diagnosis is made by computed tomography or MRI. Most of CHs occupy the lateral intraconal space with a higher morbidity than extraconal hemangiomas.
In this article a case of a CH in the superomedial intraconal space is described. Clinically, this CH was causing a throbbing retrobulbar pain, a mild proptosis, and disturbing accommodation. At the MRI evaluation, the lesion was dislocating downward, and laterally, the optic nerve and compressing the posterior pole of the eye.
Considering the clinical and radiological features, the authors performed an upper eyelid crease access with a retro-septal dissection route (SECARD) which has not been described before, to our knowledge. It has the advantage of not requiring the violation of orbital septum, avoiding its enfeeblement and fat herniation, which could happen through the standard upper eyelid crease access. Compared to a medial approach, the SECARD is more direct to the superomedial intraconal space [Figure 1] and [Figure 4]a, avoiding any disinsertion and reinsertion of extraocular muscles and every matter related. Compared to an endoscopic endonasal approach, the SECARD is more conservative: it does not need demolition of the medial wall to enter the orbit, neither its reconstruction to avoid postoperative orbital volume changes with a possible enophthalmos. It does not need any middle turbinectomy and any nasal septum resection to gain adequate space for endoscopic manoeuvres. Besides, it does not require any expertise in endoscopic endonasal surgery, which is mandatory to get good outcomes and to keep risks low., A lateral approach was also excluded firstly because it is best suitable for reaching the lateral intraconal space,, secondly because external scars, bony marginotomies, heavy extraocular muscular and bulbar retractions are inevitable. Moreover, it needs dissection through important nerves and vessels which are lateral to the optic nerve, to reach the medial part of the intraconal space. All these more invasive and time-consuming procedures can result in serious postoperative complications, such as strabismus (due to extraocular muscular transection and misposition), or muscle palsy (due to heavy tractions). Indeed, by a SECARD, it is possible to realize a more direct and rapid route with less muscular traction, bleeding, edema, orbital tissue dissection, morbidity and, therefore, better functional and cosmetic outcomes. Even if SECARD is an external approach which implies a skin scar, it requires only one incision, always well hidden inside a natural crease of the superior eyelid, without any bony osteotomy. It is also not technically demanding because of its similarity to the superior eyelid approach for the reduction and osteosynthesis of the frontozygomatic fractures.
Therefore, with regard to its low morbidity, rapidity, brilliant esthetic, and functional results, the upper blepharoplasty approach with RD route proved to be a safe promising method for removing retrobulbar intraconal superomedial masses.
