Abstract

Purpose: Chemical denervation on patients with blepharospasm(BS) and hemifacial spasm (HFS) was done using Botulinumtoxin type A(BTA) injection. It was investigated whether the duration of effect of each successive injection changes or not on the same patient and amongst patients. Methods: Eleven patients with BS (seven females, four males) and seventeen patients with HFS (Group 2; twelve females, five male) were treated with BT-A local injections (2.5 U-5U for each injection). To avoid such complications as ptosis and diplopia, pretarsal subcutaneous injections on the upper lid were done both medially and laterally whereas only laterally on the lower lid. Results: The mean age was 63.7 ± 8.3 for BS and 63.2 ± 8.3 years for HFS 2. Mean duration of symptoms before treatment was 14.0 ± 5.8 months for BS and 15.2 ± 6.9 months for HFS. The number of injections in BS was 2 to 6 injections per patient adding up to a total of 44 injec¬tions for 11 cases whereas in HFS, it was 2 to 7 injections per patient and a total of 65 injections for 17 cases. Dosage were 36,95 + 4,42 U for BS,18,98 ± Ü for HFS. All patients experienced relief from spasm. Mean duration of effect of BTA injections was 10 to 20 weeks(14,89 ± 2,97) in the BS group and 14 to 26 weeks (20,40 ± 2,54) in HFS group (p0.005). But there was minimal difference in duration of effect of injections amongst the patients (P

Özet

Amaç: Hemifasiyal spazm ve blefarospazmı olan hastalarda, botulinum toksin tip-A (BTA) enjeksiyonu uygulanarak, ardısıra yapılan herbir enjeksiyonun etkinliği, etki sürelerinin aynı hasta ve hastalar arasında farklılık oluşturup oluşturmadığı araştırıldı. Yöntem: 11 blefarospazmlı (BS) hastaya (7 kadın, 4 erkek) ve 17 hemifasiyal spazmlı (HFS) hastaya (12 kadın, 5 erkek) BTA lokal enjeksiyonları, herbir enjeksiyon 2,5 - 5 ünite olmak üzere uygulandı. Ptozis ve diplopi gibi komplikasyonlardan kaçınmak amacıyla, pretarsal cilt altı enjeksiyon üst kapakta içe ve dışa, alt kapakta ise sadece dışa yapıldı. Bulgular: BS da ortalama yaş 63,2 ± 8,3 ve HFS da 63,2 ± 8,3 idi. Tedavi öncesi semptomların ortalama süresi BS'da 14,0 ± 5,8 ay ve HFS'da 15,2 ± 6,9 aydı. BS'da enjeksiyonların sayısı 11 hasta için toplam 44 enjeksiyon olup her bir hasta için 2-6 kez enjeksiyon uygulandı. HFS'da 17 hasta için toplam 65 enjeksiyon olup her bir hasta için 2-7 kez uygulandı. BS'da ortalama 36,95 ± 4,42 ünite, HFS'da 18,98 ± 2,29 ünite BTA kullanıldı. Tüm hastalarda spazm şikayetleri kayboldu. BS hasta grubunda ortalama BTA enjeksiyon etki süresi 10-20 (14,89 ± 2,97) hafta iken HFS hasta grubunda 14-26 (20,40±2,54) haftaydı (p0,005). Fakat aynı guruptaki hastalar arasında enjeksiyon etki süreleri, birbirlerinden biraz farklıydı (P
