Orbital Exenteration Surgery

Best Orbital Exenteration Surgery in India

Exenteration – or orbital exenteration – is a surgical process that entails the resection of the eyeball and the tissues by which it is encompassed; such include the muscles, nerves, fatty tissues adjacent to the eye, and the eyelids (the degree of removal would be determined by what disease is being treated). Exenteration could either be total, subtotal or extended. By convention, the exenteration procedure is comprised of the excision of the conjunctiva, eyelids, the globe, and the orbital contents in their totality, which is inclusive of the periorbita.

Furthermore, Superexenteration, which is otherwise referred to as extended exenteration, might involve the bony orbital walls, adjacent paranasal sinus tissues, and/or intracranial tissue. Subtotal exenteration, on the other hand, is concerned with the removal of the conjunctiva, the globe, and extraocular muscles and subperiosteal dissection. When one considers the proper preservation of orbital tissue volume, eyelids, or conjunctiva, subtotal exenteration has an inclination to facilitate the use of orbital or ocular prosthesis. This, in turn, helps speed up the rate of healing, comes with much less complications, fewer modifications to the dressings made, and at the same time enhances functional and esthetic results.

Diagnosis

Every patient being put forward for exenteration surgery should be assessed in a preoperative manner, by a head and neck surgeon or ophthalmologist; in events where there is involvement of the skull base, a neurosurgical evaluation has to be conducted. On the other hand, for patients set aside for reconstruction, their examination should be conducted as due, by a reconstructive plastic surgeon. A radiological assessment is comprised of two aspects, the magnetic resonance imaging part — which is augmented using gadolinium — and a high resolution contrast-enhanced computed tomographic scan (CT scan). On one hand, the MRI provides an enumeration of intracranial and orbital involvement, and conversely, the CT scan offers an ideal representation of bony structures. In a bid to come out with more accurate staging, the examination is conducted on patients with malignant tumors on the basis of tomographic CT (PET-CT). By so doing, the surgical process and treatment are made much more straightforward as redundant processes are cut out when it concerns patients with distant metastases. Having stated that, if the metastatic disease of the patient is ascertained, the survival benefit should be juxtaposed against the morbidity of exenteration.

Preparing for Exenteration Surgery

Once the necessary examinations have been completed in the diagnostic phase, the next aspect will be about preparing for the surgery – after the date must have been fixed. The surgeon will provide you with extensive details on the procedure and also see to it that your mind is prepared to live with the loss of vision – on the eye(s) that would be operated on.

Again, you should note that medications such as blood-thinning and immunosuppressive drugs should be discontinued weeks before your orbit is exenterated – make sure you show the surgeon the medications you are using at the time of your first appointment. Additionally, you are not expected to eat anything six hours before your exenteration surgery.

Potential risks

There are a number of risks associated with exenteration surgery; some of these include:

  • Recurrence of tumors. Though tumour recurrence may not always register as a direct complication of exenteration, the manipulations that take place during this procedure do affect the anatomical integrity of the orbit and surrounding tissues to a large extent. As a result of this, early discovery of tumours when they recur may become a little more difficult.
  • Sino-orbital fistula. This is a notable complication of exenteration that involves both the orbit and ethmoid sinus and can cause serous fluid to leak. More so, an infection may result whenever sino-orbital fistula is persistent. There is a high probability of encountering this complication where immunosuppression, sinus disease, and surgical trauma to ethmoid bones exist.
  • Chronic discharge. This is largely due to sino-orbital fistula and is characterized by the drainage of pus into the orbit from the ethmoid sinus.
  • Cerebrospinal fluid leak. This occurs as the clear liquid [around the brain or spinal cord] escapes, through a small tear on the membrane covering the organ, to other parts. This is one complication that could yet bring about other far-reaching consequences, including death.

The potential complications of exenteration yet give an insight into how complex it is, and this is the very reason you should consider having your surgery in a top clinic with the right resources and the best team of surgeons to perform the procedure on you.

Operative Technique

Orbital exenteration is, more often than not, done under general anesthesia; be that as it may, for older patients with comorbidities, intravenous sedation with local anesthetic has been reported.

To get proper traction of the orbital contents, either skin sutures or a large-sized Allis clamp are routinely applied to the lid edges. Overlying the bone rim of the orbit, a circumferential skin incision is marked out or ascribed. At the initial stage, the skin is incised with a cold knife, then monopolar cautery up until the periosteum is reached successfully. The supraorbital nerve is carefully preserved in order to maintain sensation in the forehead. Save for the tight attachment of the medial and lateral canthal ligaments and the trochlea, which is best destroyed with a No. 15 blade scalpel, the periorbita separates readily temporally, above, and medially.

The thinness of the orbital roof should be properly set out so that the anterior cranial cavity is not penetrated inadvertently. As a consequence of the thinness of the nasal orbital wall over the ethmoid air cells, meticulous attention must be given to the process of elevating the periorbita to avoid opening into the nasal cavity. The anterior and posterior ethmoidal arteries are ligated and transected upon the removal of the lacrimal sac.

The neoplasm may be discovered during the separation of the periorbita along the rim or the orbital wall. As far back as the apical stump and along the superior and inferior fissures, the periorbita can be released. Monopolar cautery can be applied as a technique to clamp and cauterize the above.

Curved neurectomy scissors applied with expertise from the nasal end can be used to cut the apical stump. To prevent bleeding, the stump will almost always require further clamping and cauterization. The orbital apex’s ocular muscles, optic nerve, and ophthalmic arteries are then transected. A rongeur is utilized to remove the involved bone and bone wax might be used to stop bleeding. The orbit is now packed, and the patient can proceed with their preferred reconstructive approach.

Going by the invasiveness of exenteration; it is usually more challenging to manage the orbit thereof. Owing to this, the best exenteration procedural routine will include engaging the services of an experienced ocularist to prepare the prosthesis to place in the orbit after the surgery has been completed.

Post Operative Care

It is strongly recommended to the patients that the skin surrounding the incision be cleaned with cool, boiling water; the rest of the face can be cleansed as you would on a normal day. Patients should avoid the blowing of their noses and try to lessen vehement sneezing for 6 weeks following surgery, this is just for the reason that socket is adjacent to the air sinuses. This reduces the chance of air entering the socket and causing subsequent infection. On a closing note, sleeping with the head elevated on two extra pillows for two weeks helps to reduce bruising and swelling.

An ocular prosthesis, made of silicone, created as a replica of the other eye, is constructed to improve the cosmetic look. This can be attached to the socket with specialized magnetic implants or fixed to a pair of glasses. These prostheses are oftentimes handcrafted by a professional and usually have a very pleasing overall visual look.

All patients will require ongoing clinical monitoring for up to 5 years, as well as adjuvant local radiation and/or chemotherapy (after the socket has settled). This is organized by an oncologist with experience in the field and is thought to ‘mop up’ any residual tumor cells if they are present.
