要約 目的:高齢者の眼瞼下垂に対する術式と術後経過の報告。対象と方法:過去4年間に後天性眼瞼下垂として手術し,術後1年以上の経過を追跡できた65歳以上の症例を診療録により検索した。118例178側で,男性28例,女性90例であり,年齢は65~88歳(平均74歳)であった。顔面神経麻痺の既往が7例7側,コンタクトレンズの長期使用が1例2側にあった。全例で余剰な皮膚と眼瞼組織切除による眼瞼形成術を行い,53側で眼瞼挙筋腱膜とミュラー筋を瞼板に縫着する腱膜修復術を行った。結果:全例で眼瞼下垂が改善し,1年以内に再手術を必要とする症例はなかった。術後3年以上の観察ができた35側では6例で再手術を行ったが,再手術率に術式による差はなかった。結論:高齢者の眼瞼下垂に対しては,余剰な眼瞼組織を切除する術式が有効であり,眼瞼の重量軽減が1つの理由として考えられる。
Abstract. Purpose:To report surgical procedures and outcome of blepharoptosis in elderly persons. Cases and Method:This retrospective study was made on senile patients who received surgery for blepharoptosis during the past 4-year period, and who were followed up for one year or longer. The series comprised 178 eyes of 118 patients including 28 males and 90 females. Their age ranged from 65 to 88 years, average 74 years. Seven cases had unilateral facial palsy in the past. All the cases received blepharoplasty by excision of redundant skin and eyelid tissue. Additionally, 53 eyes received transcutaneous aponeurotic repair by levator tuck. Results:Blepharoptosis improved in all the eyes at 1 year after surgery. In 35 eyes that were followed up for 3 years or longer, 6 eyes received additional surgery. Conclusion:Blepharoplasty by excision of skin and eyelid tissue was effective for blepharoptosis in senile persons. Reduction in weight of the eyelid seemed to be a contributing factor.
