Warning: traditional liposuction cannulas may be dangerous to your patient's health.

Liposuction is the most frequently performed invasive cosmetic procedure in the United States. The vast majority of liposuctions are performed using mechanical aspirators that are connected by sterile tubing to a cannula. Although liposuction cannula shaft designs have been modified and "perfected" to various extents, little attention has been paid to the handle and handle/shaft junction. Herein we present an inherent design-induced difficulty of traditional liposuction cannulas, the inability to be optimally cleaned. In addition, we present a solution.

Where is the gray line?

The gray line is a well-known surface anatomic landmark used by surgeons in the repair of lacerations involving the lid margin. To the best of our knowledge, no description of any deep or superficial anatomic counterpart of the gray line has been previously reported. We examined block resections of 51 eyelids histologically following localization of the gray line. The visualized gray line was consistently seen to correspond histologically to the most superficial portion of the orbicularis muscle, known as the muscle of Riolan. We comment on changes in gray line morphology with lid movement, and we advance a hypothesis to explain its "gray" color.

Management of unsuccessful lacrimal surgery.

Two hundred and eight cases of failed dacryocystorhinostomy presenting to the Lacrimal Clinic at Moorfields Eye Hospital between 1970 and 1985 were reviewed. All cases underwent a further operation. The reasons for failure were usually apparent on reoperation. The surgical technique is described. A second dacryocystorhinostomy is a highly successful technique that spares both patient and surgeon the lifelong commitment to a bypass tube.

Management of complicated ptosis with contralateral levator recession.

We describe a unique approach to complicated unilateral minimal ptosis. Three cases of unilateral ptosis were successfully managed with the technique of contralateral levator recession. Contralateral levator recession is a useful procedure heretofore undescribed, to our knowledge, for the management of ptosis.

Pseudoepiphora from cerebrospinal fluid leak: case report.

A 4-year-old tearing child with obstruction of the nasolacrimal duct was treated with dacryocystorhinostomy three years after naso-orbital injury. However, what appeared to be tearing persisted, and meningitis developed. Coronal CT scans demonstrated traumatic encephalocele of the posterior superior orbital roof. A chronic orbital cerebrospinal fluid (CSF) leak was diagnosed. To our knowledge no case of chronic CSF leak has been reported that simulated tearing in an otherwise asymptomatic child. In the tearing patient who has a naso-orbital fracture the possibility of chronic CSF leak should be considered.

Total internal reflection for positioning Jones tube.

Visualization of the Jones tube in the internal nose often poses difficulty for the surgeon and threatens the success of the operation. Postoperatively, localizing the end of the tube in the nose in order to confirm its placement or to analyze the cause of failure may also be technically challenging. A method of visualizing the tube in the nose under both surgical and postsurgical conditions is herein described.

The preauricular skin graft in eyelid reconstruction.

The skin obtained from the preauricular graft for reconstruction of eyelid and midfacial defects is an excellent tissue and color match for the lower eyelid and medial canthus. This area is an excellent alternative graft site, and its usage should be added to the ophthalmic plastic surgeon's therapeutic armamentarium.

A new technique of indirect ophthalmoscopy for the eye plastic surgeon.

The coaxial fiberoptic headlight used by the lacrimal and orbital surgeon is an excellent light source for visualization of the retina. When employed in conjunction with a condensing lens, an inverted stereoscopic aerial image is produced. The eye plastic surgeon might therefore routinely examine the dilated patient in conjunction with lacrimal or orbital surgery.

New instrumentation for fluid-air exchange.

To facilitate fluid-air exchange, we have recently adapted and modified an instrument that has been designed to maintain the anterior chamber of an eye with pressurized air at levels which are pre-set by the surgeon. We have now altered this instrument to provide us with a means of performing a fluid air exchange that obviates the need for changing or refilling the air syringe. The intraocular pressure can be maintained at a predetermined level throughout the procedure, with unlimited filtered air controlled by the surgeon via an uncomplicated automated foot pedal control system.

Delayed suprachoroidal hemorrhage mimicking acute retrobulbar hemorrhage.

The signs and symptoms of an acute retrobulbar hemorrhage include sudden ocular pain, explosive unilateral proptosis, limitation of extraocular movements and loss of vision. Retrobulbar hemorrhage is a well-described complication of retrobulbar anesthetic injection. We report an unusual case of a presumed acute retrobulbar hemorrhage following intraocular surgery which, on further testing, was found to be a delayed suprachoroidal hemorrhage.
