The Investigation of the Repeatibility of the Pharyngeal Area Measurement With Lateral Cephalometric Films and Acoustic Pharyngometry Technique

Abstract

Aim; The investigation of the repeatability of acoustic pharyngometry technique and lateral cephalometric films and the present the advantages and the disadvantages of the two techniques. Methods : Two lateral cephalometric films and acoustic pharyngometry measurements were taken from 20 healty adult subjects in a week period. The acoustic pharyngometry measurements were done with cephalostate, in natural head position and orthoposition in order to prevent the negative effect of head, shoulder and tongue position and to provide standardization. Lateral cephalometric films were taken in the some conditions. The repeatability of angular, linear and area measurements derived from lateral cephalograms and the volume of analysis segment volume , mean pharyngeal cross sectional area mean area , minimum pharyngeal cross-section area min. area and minimum distance min dist derived from acoustic pharyngometry were investigated. Results : The angular measurements r = 0,99, r = 1; p < 0.001 , linear measurement and area measurements r = 0,99; p < 0,001 derived from lateral cephalogram were found to be repeatable. Analysis segment volume and mean pharyngeal cross-sectional area r = 0,96 p < 0.001 , minimum pharyngeal cross – section area r = 0,98, p < 0.001 and minimum distance r = 0,99, p < 0.001 derived from acoustic pharyngometry measurements were found to be repeatable. Conclusion : The acoustic pharyngometry technique and the lateral cephalometry were found to be repeatible when the measurement were done with cephalostate, in natural head position and orthoposition

Faringeal alan ölçümünde lateral sefalometrik filmler ve akustik faringometri yönteminin tekrarlanabilirliğinin araştırılması

Abstract

Amaç : øki farklÕ tanÕ yöntemi olan lateral sefalometri ve akustik faringometri yöntemlerinin tekrarlanabilirliklerini araútÕrmak ve her iki yöntemin avantaj ve dezavantajlarÕnÕ sunmaktÕr. Yöntem ve Gereçler : Herhangi bir sa÷lÕk problemi olmayan 20 eriúkin bireyden ortalama 1 hafta arayla 2 kez lateral sefalometrik film ve akustik faringometri kayÕtlarÕ alÕnmÕútÕr. Akustik faringometrinin baú, omuz ve dil pozisyonunda negatif etkilenmesi nedeniyle standardizasyonu sa÷lamak amacÕyla ölçümler sefalostatta do÷al baú konumunda ve ortopozisyonda yapÕlmÕútÕr. Lateral sefalometrik filmler de aynÕ koúullar altÕnda çekilmiútir. Lateral sefalometrik filmlerde açÕsal, do÷rusal ve alan ölçümlerinin akustik faringometri ölçümünde ise Analiz segmentinin hacmi Volume , ortalama faringeal kesit alanÕ Mean Area , minimum faringeal kesit alanÕ Min. Area ve minimum mesafe Min. dist de÷erlerinin tekrarlanabilirli÷i araútÕrÕlmÕútÕr. Bulgular : Lateral sefalometrik filmlerde açÕsal ölçümlerin r = 0,99 ve r = 1; p < 0,001 , Lineer ölçümler ve alan ölçümlerin r = 0,99; p > 0,001 tekrarlanabildi÷i saptanmÕútÕr. Akustik faringometri ölçümlerinde analiz segmenti hacmi ve ortalama faringeal kesit alanÕnÕn r = 0,96; p < 0,001 , minimum faringeal kesit alanÕn r = 0,98; p < 0,001 ve minimum mesafenin r = 0,99; p < 0,001 tekrarlanabilir sonuçlar verdi÷i izlenmiútir. Sonuç : Ölçümlerin sefalostatla, do÷al baú pozisyonunda ve ortopozisyonda yapÕlmasÕ úartÕyla akustik faringometri ve lateral sefalometrik filmlerin tekrarlanabilir oldu÷u sonucuna varÕlmÕútÕr
