title: Rehabilitation of the paralysed or lax lower eyelid using a graft of conchal cartilage.
abstract: Excessive laxity of the tarso-ligamentous sling of the lower eyelid may be caused by inadequate muscular support (resulting from injury to the muscle, facial palsy or senile degeneration) or prolonged mechanical distension (exophthalmia). Numerous techniques have been devised for functional reconstruction of the distended lower eyelid, based upon the principle that restoring the lower eyelid to its anatomical position will improve lacrimal transit andre-establish its natural protective function. We now use an autologous conchal cartilage graft to treat the distended or atonic lower eyelid. We review our results in a retrospective study of 20 patients, and aim to identify the indications for this procedure and to evaluate its advantages and disadvantages relative to other existing methods. All of our patients reported functional improvement after the operation in terms of decreased dry-eye symptoms, less epiphora and a decline in keratitis and conjunctivitis. All patients also reported a visible cosmetic improvement postoperatively. The major drawback of this operation is the partial loss of the visual field when looking down, due to the limited lowering of the lower eyelid. The stability of our results compares favourably with that achieved using other currently available techniques. We conclude that autologous conchal cartilage grafting is an effective procedure for improving both the function and the appearance of the atonic lower eyelid.
