In our series, we had 03 female and 05 male (Figure 1).

The age distribution of our cases varies from 26 to 76 years with an average of 33.43 year

It is defined by the time elapsed between the first clinical sign and the diagnosis. It varied between 4 days and 02 years, with an average of 09 months.

Figure 2 shows the clinical appearance of redness with proptosis, ptosis of the left eye and subconjunctival hemorrhage. The majority of patients had proptosis as a clinical sign 75%, followed by other local inflammatory signs in 03 cases, then the decline in visual acuity, followed by orbital pain in 02 cases (Figure 3).

Imaging has a key role in the diagnosis and follow-up of orbital tumors, even if the definitive diagnosis remains histological exam. Six cases out of 08 or (75%) benefited from the couple CT, and fronto-orbital MRI. Moreover, an MRI was directly requested as first intention in 01 cases (Table 1).

Lesions during orbital tumors are multiple and varied, we show you radiological aspects found in our patients in CT and MRI images (Figures 4-7).

All patients were operated (100%), and the choice of approach depended on the location of the tumor, the tumor volume and the histological type. we performed 03 lateral orbitotomies with bone removal and 05 cases by transcranial routes: 03

cases by fronto-temporo-zygomatic approach and 02 cases of fronto-pterional approach (Figure 8 and Figure 9).

The Optical Microscope was used for 06 cases and the Cryophobe device was used in 03 cases (cavernous hemangioma) (Figure 10).

The histologic study was essential to confirm the definitive diagnostic of orbital tumors. We note in our series a predominance of cavernous hemangioma, representing 37.5% of cases (Table 2).

The postoperative follow-up was evaluated on the data of the last consultation recorded in writing by a doctor of the service on the file. The average follow-up is 06 months (Figure 11). The evolution was simple in 07 cases (87.5%), with one case of a bad scar.

Two patients were lost to follow-up, which made their long-term follow-up very difficult.

The average age of discovery of orbital tumors in the literature varies between 51

and 75 years (Table 3). However, in our series we found an average age very young.

The male predominance in our series is explained by the fact that our patients are essentially soldiers, most often men.

The clinical symptomatology is largely dominated by proptosis, which constitutes 95.24%, 97%, 62.96% of the reasons for consultations in several series: CHAOUI [4], BARHDADI [5] and BELMEKKI [6], respectively, thus concurring with the results found in our study (75%). It can be isolated or associated with other clinical signs (Table 4).

Both MRI and CT are effective examinations for detecting orbital lesions [7]. The MRI has become by far the most widely used in the evaluation of orbital tumors since its appearance in 1983. In our study, we found that 87.5% of patients benefited from CT against 75% who had MRI; this showed that despite the place of MRI in orbital pathology it has not dethroned the scanner (Table 5).

The choice of the surgical approach is carefully discussed according to many criteria: clinical, topographical and histology. Wide, sub-frontal pathways with removal of the superior or pterional orbital rim will be chosen for surgery for sphenorbital meningioma, fibrous histiocytomas, lymphangiomas and smaller pathways with lateral or posterolateral orbitotomy, for tumor surgery lacrimal gland, cavernous hemangiomas, or other well-circumscribed tumors such as schwannomas [10].

Cavernous hemangioma: 02 cases were operated by lateral orbitotomy and 01 case by fronto-temporo-zygomatic flap, in two cases, the excision was complete on bloc, and one case the excision was considered subtotal (with 06-month control MRI showing a small fragment of 5 mm).

Mucocele: (02 cases) the treatment consisted on the evacuation of the contents and resection of the shell of the tumor while trying to restore the ventilation of the sinus, the choice of the fronto pterional approach was chosen to be the most

radical and to avoid recurrence.

Spheno-orbital meningioma: one case was approached by frontopteriontemporal flap, with resection Simpson 2, and we noticed a spectacular regression of clinical signs.

Ossifying fibroma: we had a single case operated by frontopterional flap with resection of the frontal bone and the tumor in its entirety then we completed the gesture by cranioplasty in a month.

Pleomorphic adenoma: we had one case of this benign tumor located in superolateral and it was totally resected by a lateral orbitotomy was the ideal approach with regression of the proptosis.

In the neurosurgical series, tumors originating from the nervous system and the meninges are in the lead (30% to 50%), followed by vascular tumors in second place (15% to 20%). In third position, tumors of ENT origin (10% to 15%). In our modest study, vascular tumors (cavernous hemangioma) are in the lead (Table 6).

The prognosis of orbital tumors is dominated by the histological nature and intracranial extension and at the base of the skull; it depends to the topography of the tumor and the importance of the invasion and the suffering of the optic nerve, and finally by the precocity and the quality of the care.

In our study, the prognosis was very good, with few complications.
