Yıl 2019, Cilt: 6 Sayı: 4, 130 - 134, 11.11.2019

Amaç: Dış
kulak yolu (DKY) maksillofasiyal travmaların (MFT) muayenesinde sıklıkla gözden
kaçırılan bir bölgedir. DKY’nin anterior ve inferior duvarları, temporal
kemiğin timpanik parçasından meydana gelir. Timpanik parça temporomandibular
eklem ile yakın ilişkidedir. Kondil DKY’e doğru kuvvet uyguladığında, kondilin
posterior ve anteromedial dislokasyonu timpanik parçada kırık ile
sonuçlanabilir. Bu çalışmanın amacı, MFT ve DKY kırıklarının ilişkisinin Konik
Işınlı Bilgisayarlı Tomografi (KIBT) kullanılarak değerlendirilmesidir.

Gereç ve Yöntemler: 2016-2019
yılları arasında alınan 65 hastanın KIBT görüntüleri; olası DKY, maksilla,
mandibula ve kondil kırıklarını saptamak için bir araştırmacı tarafından
değerlendirildi. Tanımlayıcı ve ayrıntılı istatistikler SPSS 20.0 sürümü (IBM,
ABD) kullanılarak yapıldı. Gözlemci içi güvenilirlik Weighted Cohen’s Kappa
katsayısı kullanılarak hesaplandı.

Bulgular: DKY
kırıkları, hastaların % 40’ında görüldü. DKY kırıklarının % 47.4 ve % 41.7’si
sırasıyla maksiller ve mandibular kırıklarla ilişkiliydi. DKY kırıklarının %
42.3’ü bilateraldi. Sol ve sağ kondil kırıkları, sırasıyla % 41.7 ve % 45.5
oranında ilgili tarafın DKY kırığıyla birlikte görüldü. DKY ve diğer kırıklar
arasındaki istatistiksel anlamlılığı değerlendirmek için Ki-kare testi
kullanıldı.

Sonuç: DKY’nin
timpanik parçası, maksillofasiyal travmalarda kendisine gelen kuvvete bağlı
olarak kırılabilir. Maksillofasiyal travma hastalarının değerlendirilmesinde,
DKY kırıklarını gözden kaçırmamak için KIBT görüntüleri dikkatle
incelenmelidir.

Imaging of external auditory canal fractures associated with maxillofacial traumas by CBCT

Background: The external
auditory canal (EAC) is a frequently disregarded region in the assessment of
maxillofacial traumas (MFT). The anterior and inferior walls of EAC occur from
the tympanic portion of the temporal bone. Tympanic plate is in close proximity
with temporomandibular joint. Posterior and anteromedial dislocation of the
condyle can result with fracture in the tympanic plate when the condyle is
forced against to EAC. The aim of this study to evaluate association with MFT
and EAC fractures by using Cone Beam Computed Tomography (CBCT).

Methods: CBCT
images of 65 patients undertaken between 2016 and 2019 were assessed by one
observer to detect the probable EAC, maxilla, mandible and condyle fractures.
Descriptive and detailed statistics were performed using SPSS version 20.0
(IBM, USA). Intra-observer reliability was calculated using Weighted Cohen's
kappa coefficients.

Results: EAC
fracture was determined in 40 % of the patients. Of the EAC fractures, 47.4 %
and 41.7 % were associated with maxillary and mandibular fractures,
respectively. Of the EAC fractures, 42.3 % were bilateral. Left and right
condyle fractures were detected together with 41.7 % and 45.5 % of the related
side EAC fractures, respectively. Chi
squared test was
used to evaluate statistical significance between EAC and other fractures.

Conclusion: Tympanic plate of EAC can fracture depending on the force against to
it in MFT. In the assessment of maxillofacial trauma patients, CBCT images
should be carefully evaluated not to overlook EAC fractures.
