Objectives:To determine the rate of direct visibility of incudostapedial joint during the middle ear operations in the Turkish population and to assess the complications occurring during the resection of chordal crest.Methods: Operation records of 678 patients who underwent middle ear surgery (tympanoplasty, stapes surgery, explorative tympanotomy) between 2001 and 2007 at fiiflli Etfal Teaching and Research Hospital has been investigated retrospectively. The rate of visibility of incudostapedial joint with or without intervention to chordal crest has been determined during these surgeries. Complications of surgeries at which chordal crest excised have been assessed.
Results:Incudostapedial joint has been observed directly in 513 (75.6%) ears operated while it has become visible with the excision of chordal crest in 165 (24.4%) ears. Of the 165 cases who underwent chordal crest resection, 3 (1.8%) cases had chorda tympani detachment, 6 (3.6%) cases had transient taste disturbance, 2 (1.2%) cases had perilymphatic leakage and one (0.6%) case had mild sensorineural hearing loss.
Conclusion:The rate of direct visibility of incudostapedial joint during the middle ear surgeries in Turkish population is very high. Although the rate is low, resection of the chordal crest to make the joint visible can cause some kind of complications.
ÖzetAmaç: Türk toplumunda, orta kulak operasyonlar›nda inkudostapedial eklemin (‹SE) direkt görülebilme oran›n›n belirlenmesi, kordal krest eksizyonu s›ras›nda oluflabilecek komplikasyonlar›n de¤erlendirilmesi.Yöntem: fiiflli Etfal E¤itim ve Araflt›rma Hastanesi 2. KBB Klini¤inde 2001-2007 y›llar› aras›nda orta kulak cerrahisi (timpanoplasti, stapes cerrahisi, eksploratif timpanotomi) uygulanan toplam 678 hastan›n operasyon kay›tlar› retrospektif olarak incelendi. Bu operasyonlar esnas›nda ‹SE'nin kordal kreste mü-dahale edilmeden direkt ya da eksize edilerek görülme oranlar› araflt›r›ld›. Kordal krestin al›nd›¤› operasyonlarda meydana gelen komplikasyonlar belirlendi.
Bulgular:Opere edilen kulaklar›n 513 (%75.6)'ünde ‹SE direkt olarak görülürken, 165 (%24.4)'inde kordal krest al›narak eklem de¤erlendirilebilmiflti. Kordal krest al›nan 165 olgunun 3 (%1.8)'ünde korda timpani kopmas›, 6 (%3.6)'s›nda geçici tat duyusu bozulmas›, 2 (%1.2)'sinde perilenf s›z›nt›s›, 1 (%0.6)'inde hafif dereceli nörosensoriyal iflitme kayb› meydana gelmiflti.Sonuç: Türk toplumunda, orta kulak operasyonlar›nda ‹SE oldukça yüksek oranda direkt olarak görülebilmektedir. ‹nku-dostapedial eklemi görmek için yap›lan kordal krest eksizyonuna ba¤l› az da olsa ciddi komplikasyonlar oluflabilir.Anahtar Sözcükler: Orta kulak cerrahisi, inkudostapedial eklem, kordal krest, eksploratif timpanotomi.
