ABSTRACT
Objective: To evaluate the diameter of the narrowest portion
of the eustachian tube [osseo-cartilaginous (OC) junction] in unilateral
chronic otitis media (COM) patients to determine whether this
portion plays a role in the etiology. Material and Methods: A retrospective
review was made of 146 patients who had undergone surgery
for unilateral COM. The patients were separated into 2 groups; patients
who had undergone tympanoplasty for COM without cholesteatoma
(TP group) and patients who had undergone tympanoplasty and mastoidectomy
for cholesteatoma (CH group). The contralateral healthy
sides of the patients constituted the control group (CG). Results: In the
TP group (89 patients), the mean diameter of the OC junction was
1.61±0.49 mm on the diseased side and 1.65±0.50 mm on the healthy
side. In the CH group (57 patients), the mean diameter of the OC junction
was 1.62±0.47 mm on the diseased side and 1.65±0.47 mm on the
healthy side. Although the mean diameter was higher on the healthy
side in both groups, the comparisons of the healthy side and diseased
side did not show statistical significance in the TP and CH groups (respectively
p=0.627; p=0.739). No statistically significant difference
was determined between the TP and CH groups in respect of the OC
junction diameter on the diseased side (p=0.915). Conclusion: The present
study has shown that OC diameter is similar in different cases of
unilateral COM and in healthy ears. OC diameter may be an important
factor on the etiology of C

ÖZET
Amaç: Tek taraflı kronik otitis media (KOM) hastalarında, östaki
tüpünün [osseo-kartilajinöz (OK) birleşkesi] en dar kısmının çapını
ölçmek ve bu bölümün etiyolojide rol oynayıp oynamadığını
belirlemek. Gereç ve Yöntemler: Tek taraflı KOM ameliyatı geçiren
146 hasta, retrospektif olarak incelendi. Hastalar 2 gruba ayrıldı; kolesteatom
olmadan KOM için timpanoplasti geçiren hastalar (TP
grubu) ve kolesteatom için timpanoplasti ve mastoidektomi geçiren
hastalar (CH grubu). Hastaların kontralateral sağlıklı tarafları, kontrol
grubunu (CG) oluşturdu. Bulgular: TP grubunda (89 hasta), OK bileşkesinin
ortalama çapı hastalıklı tarafta 1,61±0,49 mm ve sağlıklı tarafta
1,65±0,50 mm idi. CH grubunda (57 hasta), OK bileşkesinin
ortalama çapı hastalıklı tarafta 1,62±0,47 mm, sağlıklı tarafta ise
1,65±0,47 mm idi. Her 2 grupta da ortalama çap, sağlıklı tarafta daha
geniş olmasına rağmen sağlıklı taraf ve hastalıklı tarafın karşılaştırmasında
TP ve CH gruplarında istatistiksel olarak anlamlılık tespit
edilmedi (sırasıyla p=0,627; p=0,739). TP ve CH gruplarının, kendi
aralarında hastalıklı taraftaki OK bileşke çapı açısından da istatistiksel
olarak anlamlı bir fark bulunmadı (p=0,915). Sonuç: Bu çalışma,
OK bileşke çapının tek taraflı farklı KOM vakalarında ve sağlıklı kulaklarda
benzer olduğunu göstermiştir. OK çapı, KOM etiyolojisinde
önemli bir faktör olabilir, ancak heterojenik çalışma grubumuzda bunu
gösteremedik.
