Abstract: Lid surgery & paralytic lagophthalmos...

This is not directly related to dry eye but we have so many members whose primary dry eye cause is lagophthalmos from a variety of causes that I want to make sure and cover it all (no pun intended).

This one's a review of success to date with temporalis muscle transfer as a treatment of paralytic lagophthalmos.

Temporalis muscle transfer for paralytic lagophthalmos, which was first proposed by Gillies and later developed by Andersen, has been one of the most common treatment modalities for paralytic lagophthalmos. However, there have been no scientific reports statistically analysing the efficacy of temporalis muscle transfer. We, therefore, retrospectively analysed the functional and aesthetic results of temporalis muscle transfer. Between 1994 and 2006, we carried out temporalis muscle transfer (the so-called Gillies-Andersen method) on 95 established facial paralysis patients. We sent a postal questionnaire to these patients and 47 of them responded. The functional and aesthetic results were analysed based on the patients' replies together with clinical records and photographs, and unfavourable factors of this procedure were investigated. After surgery, most ocular symptoms (mechanical irritation, dry eye, soreness, and discharge) improved significantly. Achievement rate of complete eye closure was 78.7%. A morphometric study revealed that possible unfavourable factors (old age, intracranial disease, use of dentures, etc.) did not affect the achievement rates of complete eye closure. Deformity of eyelid fissure due to undue tension of the temporal fascia fixation was found in nine patients (19.1%) and six of these patients underwent secondary revision. Unlike lid loading with a gold implant, the results of temporalis muscle transfer depend greatly on the surgeon's skill. However, if this procedure is performed properly, strong eye closure can be obtained. We, therefore, recommend temporalis muscle transfer as the preferred option for reconstruction of paralytic lagophthalmos.
