Evaluation of Dynamic Magnetic Resonance Imaging in Assessing Velopharyngeal Insufficiency During Phonation
(Lippincott Williams & Wilkins, 2008) Atik, Bekir; Bekerecioglu, Mehmet; Tan, Onder; Eflik, Omer; Davran, Ramazan; Arslan, Halil
Background: Velopharyngeal insufficiency (VPI) expresses the structural and neuromuscular disorder of soft palate and pharyngeal walls inhibiting the normal functions of velopharyngeal (VP) sphincter mechanism. In this study, efficacy of dynamic magnetic resonance imaging in the diagnosis of VPI is investigated. Materials and Methods: A total of 32 cases, 16 controls and 16 cleft palates, were included in this study. T1 fast spin echo-weighted imaging during rest, dynamic investigations with True-fast imaging with steady-state precession sequence during /sss/ and /mmm/ phonations were performed. Results: During /sss/ phonation, complete closure was observed in the control group, whereas mean VP opening was 4.11 cm(2) preoperatively and 0.21 cm(2) postoperatively in the cleft palate group. In the postoperative period, only 3 patients did not have complete closure. In the second operations, performed 6 months later, only muscle repair was done. All 3 had complete closure. Conclusions: In cleft palate cases with delayed diagnosis, appropriate application of muscle repair will be sufficient for anatomic repair of VPI without any extra procedures. In addition, dynamic magnetic resonance imaging is an objective, noninvasive, reliable, and effective modality that may be used in the diagnosis and treatment of VPI without any extra investigations.
Trakeal Tümörü Taklit Eden Özefagus İndentasyonunda Sanal Bronkoskopinin Tanıya Katkısı
(2003) Davran, Ramazan; Sakarya, M. Emin; Temizöz, Osman
Multidedektör bilgisayarlı tomografi (BT) cihazlarının geliştirilmesinden sonra hava yollarının yüksek rezolüsyonlu sanal endoskopik görüntüleri elde edilebilmiştir. Sanal bronkoskopi ile lümen içerisinde fiberoptik bronkoskopi görüntülerine benzer görüntüler elde edilmektedir. Sanal bronkoskopi özellikle lümen içerisindeki tümörlerin ve trakeobronşial stenozlarm değerlendirilmesinde yararlı noninvaziv bir görüntüleme yöntemidir. Bu makalede aksial BT görüntüleri ile yanlış tanı konulan, özefagusun trakea lümenine indentasyonu olgusu sunulmuştur. Bu hastada doğru tanı sanal bronkoskopi ile konuldu. Sonuç olarak sanal bronkoskopinin intratrakeal tümör ve anatomik yapıların ayırıcı tanısına katkıda bulunabileceğini düşünüyoruz.
