[Colobomatous cyst of the orbit in congenital microphthalmos].

Colobomatous orbital cyst with microphthalmos is an anomaly of the orbital contents occurring during embryogenesis. In this study, we report the case of a 3 year-old child referred with the initial diagnosis of voluminous orbital angioma. Radiological investigations and histological study of the ablated mass established the correct diagnosis of colobomatous cyst. Pathogeny, diagnostic and therapeutic problems are discussed.

[Bovine heterologous bone graft in orbital surgery].

Lubboc (T650) is a bovine heterologous bone implant obtained by specific preparation of trabecular of bone. In vitro and in vivo biocompatibility studies have revealed the absence of any cytotoxicity or systemic toxicity. Lubboc has many fields of application, including all bone graft surgical indications. We report our first results concerning the use of this product in orbital surgery either as a filling or contention material or as an apposition material. On all 20 operated patients we did not encounter any intolerance, inflammation or infection. The follow-up is still too short to appreciate the long term integration of this material which has the advantage of being a substitute for autologous bone, avoiding bone graft harvesting.

[Surgical treatment of myopathic ptosis. Apropos of 20 surgically treated cases].

Twenty cases of severe progressive ophthalmoplegia (Myopathic ptosis) with significant ptosis were treated by various procedures, including levator resection with blepharoplasty or frontalis suspension using temporalis fascia. Surgical indications were generally limited to cases with poor or absent levator function. The results are analysed after an average follow-up of 6 months. The particular problems concerning surgery of myopathic ptosis are discussed.

Orbito-palpebral reconstruction in anophthalmos and severe congenital microphthalmos.

In patients with congenital anophthalmos and severe microphthalmos, a tiny orbit and socket exist with little eyelids, frequently preventing retention of a standard conformer or prosthesis. Socket expansion is sometimes impossible with microorbitism; the retention of a prosthesis is also difficult when malformations of the eyelids exist. The treatment of these difficult cases includes three stages. The first stage is orbital expansion that depends on the cephalometric studies of the patient: transverse osteotomy on the maxilla and the zygomatic bone with lateral bar by extracranial route, vertical osteotomy on the roof of the orbit by intracranial route. In some cases, the osteotomy includes expansion in the transverse and vertical diameter with bone grafts in the defects and on the lateral and superior rims. Simultaneously, socket expansion is performed by incision of the conjunctival sac circumferentially, with mucosal or split skin grafts on a conformer. The second stage includes eyelid reconstruction by different flaps. A third stage is frequently needed for correction of eyelid malposition on the prosthesis: ptosis, entropion surgery. Two cases of congenital anophthalmos are reported. Methods and indications of treatment are discussed.

Orbito-palpebral reconstruction in two cases of incomplete cryptophthalmos.

Two cases of congenital symblepharon (variant of cryptophthalmos) are reported. Cryptophthalmos is a very rare congenital defect, with incomplete or complete failure in the development of one or both eyelids with skin recovering the anterior segment. Surgical treatment is described including expansion of the conjunctival fornix with eyeball conservation if possible. At the same time or later, the upper eyelid is reconstructed by inferior eyelid flap. The ophthalmic features of cryptophthalmos and its systemic associations are reviewed.

[Orbital lymphangioma. Apropos of 2 uncommon cases].

Lymphangiomas can be considered as hemodinamically isolated vascular hamartomas. They are rare tumors, and their orbito-palpebral location can be cosmetically and functionally detrimental. In severe cases, the treatment is mainly surgical and effective only if complete removal is performed. The result is often deceiving because of the diffuse extension of these tumors. We hereby report two exceptionally severe cases that both presented with major cosmetic impairment and visual loss. We discuss literature available, the management and the methods of treatment and the non-surgical alternatives.

[The aging eyelid].

The ocular adnexal tissues share the progressive loss of tone and bulk, common to many aging tissues. As a result of these progressive involutional changes lid anatomy is altered inducing senile ptosis, ectropions, entropions, canthal laxity and epitheliomas. A better understanding of these conditions allows more appropriate surgical management. Senile ptosis is an acquired ptosis usually due to dehiscence or disinsertion of the levator aponeurosis (below the orbital septum); surgery aims to reattach it to the tarsal plate via either anterior or posterior approach. Senile ectropions and entropions share several aetiologic factors: horizontal laxity, lid retractors, laxity migration of the preseptal orbicularis for senile entropion; stretching of the canthal tendons, secondary skin retraction and conjunctival thickening for senile ectropion. The entropion requires the association of horizontal lid shortening, lower eyelid retractors shortening, skin blepharoplasty with deep sutures (between preseptal and pretarsal orbicularis). In some cases of senile ectropions, the horizontal shortening of the eyelid by a full-thickness pentagon resection with shortening of the lower eyelid retractors must be associated with a medial canthal tendon plication and skin graft.

Use of GORE-TEX (polytetrafluoroethylene) in the anophthalmic socket.

The GORE-TEX soft tissue patch is composed of large open spaces surrounded by polytetrafluoroethylene (PTFE) fibers connected to nodules of solid PTFE. It was used in 12 oculoplastic surgery patients. Primary and secondary spherical silicone implants were wrapped with a GORE-TEX patch and implanted into Tenon's capsule. This study reports our first results using this versatile material.

[Choice of treatment in surgery of congenital ptosis].

Because of the great variety of congenital ptosis and surgical procedures, the choice of a definite surgical protocol is rather difficult. The author reports here three surgical techniques which have been used for over 5 years. The levator muscle resection with upper lid fold reconstruction via a skin approach is still the preferred technique in most cases. The main problem is to determine the magnitude of muscle resection which is directly related to the levator function. Frontalis suspension with autogenous fascia-lata or synthetic materials as Goretex is performed in case of levator resection failure: non-functioning muscle, muscular dysfunction as in the Marcus Gunn syndrome. The conjunctiva-Müller's muscle excision avoiding overcorrection is indicated in cases of minor congenital ptosis with good muscular function and positive response to topical 10% epinephrine drops.

The management of congenital malpositions of eyelids, eyes and orbits.

Congenital malformations of the eye and its adnexa which are multiple and varied can affect the whole eyeball or any part of it, as well as the orbit, eyelids, lacrimal ducts, extra-ocular muscles and conjunctiva. A classification of these malformations is presented together with the general principles of treatment, age of operating and surgical tactics. The authors give some examples of the anatomo-clinical forms, eyelid malformations such as entropion, ectropion, ptosis, levator eyelid retraction, medial canthus malposition, congenital eyelid colobomas, and congenital orbital abnormalities (Craniofacial stenosis, orbital plagiocephalies, hypertelorism, anophthalmos, microphthalmos and cryptophthalmos).

The surgical management of orbitopalpebral neurofibromatosis.

Orbitopalpebral neurofibromatosis may cause severe soft tissue deformity. Exophthalmos is either due to an intraorbital mass or to the absence of the greater wing of the sphenoid (mesodermal dysplasia). Five patients are presented. Surgical procedures and craniofacial techniques are detailed and discussed.

[Supra-tarsus sulcus. Treatment by silicone prosthesis].

In the anophthalmic socket, the deep superior eyelid sulcus is a quite common syndrome; sometimes with ptosis of the upper eyelid and laxity of the lower eyelid. The treatment by a silicone prosthesis in the deep sulcus fills eyelid volume. The main advantages of this procedure are simplicity and relative harmlessness. The authors relate their technique and the results about 15 cases. The indications are discussed.
