ABSTRACT A devastating sequela of facial paralysis is the inability to close the eye. The resulting loss of corneal protection can lead to exposure keratitis, corneal ulceration, and potentially permanent vision loss. Methods to address lagophthalmos historically have included tarsorrhaphy, lid weighting, levator palpebrae superioris lengthening, chemodenervation to yield protective ptosis, and the placement of magnetic eyelid springs. The gold eyelid weight, introduced nearly 50 years ago, continues to enjoy immense popularity, despite high complication rates and nearly uniform visibility under the skin. The authors hypothesized that a commercially available, thin platinum weight would combat the visibility of the thicker gold weights and herein compare complication rates and visibility rates with literature-reported data for gold weights.
Beginning in 2004, 100 consecutive patients presenting to the authors' Facial Nerve Center with paralytic lagophthalmos requiring intervention were treated with thin-profile platinum eyelid weights. Ninety-six percent of cases were performed under local anesthesia in the office setting.
Median follow-up was 22 months. In 102 weights placed, there have been six complications (5.9 percent): three extrusions, two capsule formations, and one case of astigmatism. All of the extrusions involved irradiated patients with parotid malignancies.
The authors report the first large series of thin-profile platinum eyelid weight implantations for the treatment of lagophthalmos. This implant significantly reduces both capsule formation phenomena and extrusion compared with gold weights and should be considered as alternative to the more conventional gold implants.

    ABSTRACT: For the definitive treatment of lagophthalmos and satisfactory rehabilitation of the affected eye, different surgical strategies have been proposed, including static or dynamic procedures. Although some of these can have good results, lid loading is now the most common technique for treating paralytic long-term lagophthalmos. Among the different types of loading, the use of a platinum chain is preferred to the use of a standard gold weight because platinum has a higher density than gold and is also more biocompatible. In this paper authors retrospectively analyzed 43 patients with regards to functional and cosmetic results. Questionnaires were also employed to assess changes and improvements in the patients' quality of life. Analysis of the excellent results achieved confirmed that platinum chain lid loading should be considered as a first-line treatment for paralytic lagophthalmos rehabilitation. It is a simple, reliable, and effective technique that significantly improves the health-related quality of life of patients. Copyright © 2014 European Association for Cranio-Maxillo-Facial Surgery.

    ABSTRACT: The facial nerve is the most commonly paralyzed nerve in the human body. Facial paralysis affects aesthetic appearance, and it has a profound effect on function and quality of life. Management of patients with facial paralysis requires a multidisciplinary approach, including otolaryngologists, plastic surgeons, ophthalmologists, and physical therapists. Regardless of etiology, patients with facial paralysis should be evaluated systematically, with initial efforts focused upon establishing proper diagnosis. Management should proceed with attention to facial zones, including the brow and periocular region, the midface and oral commissure, the lower lip and chin, and the neck. To effectively compare contemporary facial reanimation strategies, it is essential to employ objective intake assessment methods, and standard reassessment schemas during the entire management period.

    ABSTRACT: To evaluate the range and incidence of facial palsy etiologies in cases presenting to a tertiary facial nerve center, and to review the broad and evolving spectrum of diagnostic and management approaches to the condition. Retrospective chart review. Records of patients referred for facial weakness between 2003 and 2013 were reviewed for cases of facial palsy. Cases of muscle dysfunction and primary hemifacial spasm were excluded. The remainder were analyzed by age, sex, and diagnosis. Diagnostic and treatment strategies were reviewed. There were 1,989 records that met inclusion criteria. Bell's palsy accounted for 38% of cases, acoustic neuroma resections 10%, cancer 7%, iatrogenic injuries 7%, varicella zoster 7%, benign lesions 5%, congenital palsy 5%, Lyme disease 4%, and other causes 17%. Sixty-one percent of patients were female. Mean age at presentation was 44.5 years (±18.6 years). Diagnoses were revealed primarily by history, though serial physical examinations, radiography, and hematologic testing also contributed. Management strategies included observation, physical therapy, pharmacological therapy, chemodenervation, facial nerve exploration, decompression, repair, and the full array of static and dynamic surgical interventions. Bell's palsy remains the most common facial palsy; females present more often for evaluation. Comprehensive diagnostic investigation is mandatory in atypical cases, and thorough management must be multidisciplinary. The algorithms presented herein outline a single center's approach to the facial palsy patient, providing a framework that clinicians caring for these patients may adapt to their specific settings. 2b Laryngoscope, 2013.
