SUCCESS- successful retrobulbar block is accompanied by anesthesia, akinesia, and abolishment of the oculocephalic reflex. Orbit anatomy 1. Orbit anatomy -Dr. Prajakta Matey. -(resident at BJGMC) 2. Introduction Orbit is the anatomical space bounded: *Superiorly-Anterior cranial fossa *Medially - Nasal cavity & Ethmoidal air cells *Inferiorly -Maxillary sinus *Laterally-Middle cranial fossa Made up of 7 bones : -Ethmoid -Frontal -Lacrimal -Maxillary -Palatine -Spenoid -Zygomati Applied Anatomy Protects only the posterior part of globe Hence palpation of retrobulbar tumors is easier from lateral side than nasal Since lateral wall is almost devoid of foramina bleeding is less The Zygomatico-Sphenoid suture important landmark in creating the flap in lateral orbitotomy. 30

Orbitotomy The eye orbit is the name given to the socket of the eye in which the eye and other associated parts of the anatomy of the eye are located. The eye socket also consists of ocular muscles and blood structures which supply blood to the eyes. Orbital tumors can grow anywhere in the orbit [ Inferior transconjunctival approach to the orbital floor. A, Canthotomy, cantholysis, and conjunctival incision.

Share yours for free -The arterial supply to the eyeball, orbit, and eyelid comes primarily from the ophthalmic artery, which is a branch of internal carotid artery.-The central retinal artery, first branch of the ophthalmic artery pierces the optic nerve. It is the only blood supply to the retina Lateral Orbital Approach The approach to the intraconal orbital space for ONSF through the lateral conjunctiva was first described in 1872. 1 Subsequently, the lateral approach was modified by a number of surgeons to improve access to the optic nerve. In 1988, Tse and colleagues described a lateral orbitotomy approach for ONSF.50 The procedure.
During lateral orbitotomy surgery, cutting the rim through to this thin plate allows easy outward fracture of the bone and access to the intraconal space.

The orbital cavity was filled by rotating the temporalis muscle into the cavity via a lateral orbitotomy. If facial skin was involved and required resection, a microvascular free flap of muscle and skin was utilized to fill the defect. The whole operation was conducted in such a manner as to avoid any contamination from the nasal operation and. Radiation Therapy: At The New York Eye Cancer Center most patients are treated with low-dose external beam or implant radiation therapy. Radiation has been used used to treat leaking choroidal hemangiomas for decades. The differences are, that in the past relatively large doses of radiation were used and some collateral radiation damage occurred An orbital fracture is when there is a break in one of the bones surrounding the eyeball (called the orbit, or eye socket). Usually this kind of injury is caused by blunt force trauma, when something hits the eye very har Symptoms. Patients with basal cell carcinomas most commonly notice a reddish nodule slowly forming on their eyelid. The tumor is most commonly found on the lower eyelid, followed by the medial canthus (skin toward the nose) and can occur on the upper eyelid. Eyelash loss (around the tumor) suggests that a basal cell carcinoma is malignant

. A lateral approach could have been used yet it would have required an osteotomy extending along the lateral orbital wall that was posteriorly fragmented. This would have required enlarging the bony incision of a classic lateral orbitotomy and. CMF Members only. Become a CMF member; A A craniotomy is the surgical removal of part of the bone from the skull to expose the brain. Specialized tools are used to remove the section of bone called the bone flap. The bone flap is temporarily removed, then replaced after the brain surgery has been done. Some craniotomy procedures may use the guidance of computers and imaging (magnetic.

If they slowly grow, optic nerve melanocytoma can produce afferent pupillary defects (30%), subretinal fluid (10%), and an enlarged blind spot (75%). For example, if the tumor is next to the optic nerve, growth can compress the nerve and cause loss of vision (e.g. nerve fiber layer defects). Growth can also cause compressive vascular problems.

Ocular adnexal lymphoma (OAL) is a localized form of systemic lymphoma affecting the orbit, the lacrimal gland, the lids and/or the conjunctiva. It comprises 6-8% of orbital tumors, and 10-15% of adnexal lesions The most common cause of lower eyelid entropion is an age-related instability of the eyelid structures. Other less common causes of lower eyelid entropion include previous trauma, chemical injuries, and inflammatory disorders of the conjunctiva on the inner aspects of the eyelids
