Auricular Cartilage Graft for Lengthening Levator Muscle Aponeurosis With Ectropion Correction for Paralytic Lagophthalmos.

Abstract

Paralytic lagophthalmos can have devastating consequences for vision if left untreated. Several surgical techniques have been described, including the utilization of alloplastic and autologous materials. The authors sought to evaluate the effectiveness of the surgical treatment of paralytic lagophthalmos with combined techniques employing autologous material and involving the upper and lower eyelids. Patients with paralytic lagophthalmos underwent stretching of the levator aponeurosis with interposition of conchal cartilage in the upper eyelid associated with sectioning of the orbitomalar ligament and lateral canthoplasty in the lower eyelid. The effectiveness of the technique was evaluated employing subjective (symptomatology) and objective parameters (ophthalmologic evaluation and measurements of lagophthalmos and marginal reflex distances 1 and 2). Eight patients with paralytic lagophthalmos were subjected to the proposed technique. In the postoperative period, 85.7% reported complete improvement of symptoms and 62.5% presented a normal eye examination. The mean lagophthalmos measurement was reduced by 5.93 mm, the mean marginal reflex distance 2 was reduced by 2.61 mm, and the mean marginal reflex distance 1 was reduced by 0.69 mm. The technique presented herein, employing autologous material associated with sectioning of the orbitomalar ligament and lateral canthoplasty, was effective in the treatment of paralytic lagophthalmos and did not present significant complications, such as extrusion.
