was performed and the anterior chamber was cannulated medially at the limbus with a 30-gauge needle (Fig 1) connected to a system consisting of a pressure monitoring kit (Transpac IV Monitoring Kit; ICU Medical Inc, San Clemente, CA, USA) with a transducer, polyethylene tubes, monitoring cable (Transpac Reusable Cable; Hospira Inc, Lake Forest, IL, USA), and a monitor (CARESCAPE Monitor B650; GE Healthcare Finland Oy, Finland).
Computed tomography is commonly used to further evaluate the orbits as it is often immediately available unlike magnetic resonance imaging which often cannot be obtained in a timely manner. Lateral canthotomy
is regarded as a first-line intervention for decompression of the orbit in OCS, and preferably, it should be performed within an hour or 2 h as it was suggested by some authors., Immediate lateral canthotomy
and inferior cantholysis are recommended to prevent visual loss owing to optic nerve compression in OCS.
An emergent lateral canthotomy
and inferior and superior cantholysis was performed at the bedside.
Eyelid reconstructive technique included various procedures like direct closure for defects measuring less than 25%, direct closure with lateral canthotomy
and cantholysis for defects measuring slightly larger than 25%, Tenzel semicircular rotational flap for defects up to 2/3rd of upper or lower lid width.
A lateral canthotomy
and transection of the lateral canthal tendon were performed.
Orbital hematoma is oftentimes obvious to recognize on physical examination by rapid unilateral orbital swelling and thus is easily treated with decompression (i.e., lateral canthotomy
To increase flap's mobility it could be necessary to perform a lateral canthotomy
The patient was also found to have an elevated ocular pressure, so she agreed to canthotomy
and cantholysis to lower it.
Clinical examination revealed proptosis which was surgically managed by lateral canthotomy
followed by temporary tarsorrhaphy.
The treatment in case of orbital emphysema accompanied by increasing symptoms (especially deterioration of vision) should include one of the procedures: lateral canthotomy
, inferior and/or superior cantholysis, orbital decompression, or simple puncture of the air vessel which may prevent the patient from blindness [11, 12, 15, 19].
Traditional surgical approaches include incisions over the mass; above, below, or through the brow; parallel to superior orbital rim; via lateral canthotomy
and lateral orbitotomy.
and inferior cantholysis: an effective method of urgent orbital decompression for sight threatening acute retrobulbar haemorrhage.
