Orbital fracture evaluation by coronal computed tomography.

Coronal computed tomography produces orbital scans in a plane that is analogous to Caldwell-view x-ray films. Coronal computed tomography permits simultaneous visualization of the orbital walls and the orbital soft tissues, including all extraocular muscles. Using coronal computed tomography, we studied a series of patients with radiographically proven orbital floor fractures. We studied in detail three of these patients, one with a linear orbital floor fracture, one with a depressed orbital floor fracture, and one with a severely comminuted orbital floor. In two patients, coronal computed tomography showed inferior rectus muscle entrapment, which was confirmed at the time of surgery. In each patient, some bone fragments could be seen more discreetly on coronal computed tomography than on conventional polytomes. Coronal computed tomography may be used to help confirm extraocular muscle entrapment in patients with orbital floor fractures. Coronal computed tomography can also be used to examine patients with possible intraorbital foreign bodies, unexplained reduction of vision, or severely displaced bone fragments.

Osteomas of the orbit.

Clinical and histologic features of osteomas are reviewed. Techniques are described for the evaluation of osteomas, including the use of coronal and axial plane computed tomography. A series of 14 patients evaluated at the Massachusetts Eye and Ear Infirmary over a five-year period is presented. Two of these patients are discussed in detail. Two surgical approaches to osteomas of the frontal sinuses are described. A brow incision is recommended for tumors primarily within the orbit. A coronal incision and osteoplastic operation is recommended for tumors primarily within the sinuses. In one patient, unusually rapid tumor growth is documented by x-rays taken over a three-year period.

Marginal tarsorrhaphy: a technique to minimize premature eyelid separation.

By using a continuous intermarginal monofilament suture, a partial tarsorrhaphy can be performed which has a minimal tendency to separate prematurely. This technique is especially useful where recovery from facial paralysis is anticipated. Surgical division of the tarsorrhaphy can be performed easily with little, if any, defect of the eyelids.

Staged excision and reconstruction of extensive facial-orbital tumors.

Extensive facial-orbital tumors are basal cell carcinomas which are exceptionally difficult to treat by conventional therapy because of: (1) skin involvement of more than one square inch of the eyelids of face; (2) fixation to bone or periosteum at the orbital rim; and (3) extension onto the inner surface of the eyelid or through the orbital septum. Due to indistinct skin margins, visual impressions of the extent of these tumors are unreliable. Radiation is usually contraindicated because of possible bone involvement. Single stage excision of the entire tumor with frozen section evaluation of the margins is difficult because of the extent of the facial and orbital components of the lesion. A technique is described which involves staged excision and reconstruction of such extensive tumors. Stage one involves lamellar resection of the skin tumor. Lamellar resection is a modification of the Mohs technique, using permanent section evaluation of all margins, after which the surgical defect is allowed to heal by granulation or is grafted. Stage two involves en bloc resection of the remaining tumor, with frozen section evaluation of all margins. Stage three involves later cosmetic and functional reconstruction of the orbit and eyelids in a tumor-free location. The use of this technique is demonstrated by the description of a patient who would probably have required exenteration if conventional surgical methods had been used.

The Use of Computer Tomography in Ophthalmology.

Fifty-three orbital lesions of various types were studied by computer tomography to assess the capabilities and limitations of this technique. Although CT scanning in ophthalmology is in its infancy, results showed that it is useful in the investigation of a number of pathological conditions, including congenital anomalies, arteriovenous malformations, bone lesions, trauma, inflammation, granulomas, pseudotumors, epidermoid cysts, and tumors arising in or near the optic nerve, behind the optic bulb, or in the lacrimal region, as well as changes following eye surgery.

A method for combined dacryocystorhinostomy with external ethmoidectomy.

Severe polypoid rhinosinusitis requiring external ethmoid surgery may be seen in conjunction with partial or complete nasolacrimal obstruction. When this obstruction is associated with persistent, unresolved lacrimal symptoms, it is sometimes appropriate to combine surgical procedures, thereby avoiding separate lacrimal surgery. A method combining dacryocystorhinostomy (DCR) with external ethmoidectomy is described. The anatomy involved in this procedure and the indications for it are discussed.

Early acute aseptic iritis after cataract extraction.

Severe iritis which occurs within the first five days after cataract extraction may be categorized as (1) bacterial endophthalmitis, (2) toxic iritis, or (3) aseptic iritis. These entities can sometimes be distinguished because of their clinical features. If bacterial endophthalmitis is suspected, anterior chamber paracentesis should be considered and appropriate antibiotic treatment should be initiated. Acute iritis may result from the introduction of toxic agents into the eye, and may follow the use of products sterilized with ethylene oxide. Early acute aseptic iritis probably occurs more often than has previously been recognized. Response to intensive anti-inflammatory treatment is usually prompt and dramatic. The judicious use of cryoextraction and the careful manipulation of intraocular tissues may minimize the incidence and the severity of postoperative inflammation.
