PREVALENCE AND CHARACTERISTICS OF PNEUMATIZED ARTICULAR EMINENCE ON PANORAMIC RADIOGRAPHS: A RETROSPECTIVE STUDY AND LITERATURE REVIEW

Öz

Objective: Pneumatized articular eminence (PAE) is an air filled cavity in temporal bone. The aim of this research was to evaluate the prevalence and characteristics of PAE using panoramic radiograhy.

Material and Methods: The panoramic radiographs of 1000 patients were analyzed to describe prevalence and characteristics of PAE. Patients with PAE had a mean age of 35 years with a range of 19–85 years. Gender, age, localization and locularity of pneumatization were noted.

Results: PAE was found in 19 (1.9%) patients with a mean age of 34.4. Twelve patients were female and seven patients were male. There was no statistically significant difference between gender and the presence of PAE (p>0.05). 12 unilateral and 7 bilateral cases were observed. Nine patients (47.4%) had PAE on the left side while three patients (15.8%) had PAE on the right side. Unilocular appearances were found in 7 patients (36.8%) while multilocular appearances were found in 11 patients (57.9%). One patient (5.3%) had both unilocular and multilocular types.

Conclusion: Awareness for this anatomical variation is important for differential diagnosis from other lesions and also for planning temporomandibular joint surgery. Because of fragile structure of bone with PAE, the surgeons should be careful during temporomandibular joint operations.

Panoramik Radyograflarda Pnömatize Artiküler Eminens Prevalansı ve Özellikleri: Retrospektif Bir Çalışma ve Literatür Taraması

Öz

Amaç: Pnömatize artiküler eminens (PAE), temporal kemikte hava dolu bir boşluktur. Bu araştırmanın amacı, panoramik radyografi kullanılarak PAE prevalansını ve özelliklerini değerlendirmektir.

Gereç ve Yöntemler: PAE prevalansı ve özelliklerini tanımlamak için 1000 hastanın panoramik radyografileri analiz edildi. PAE görülen hastaların yaş ortalaması 35, yaş aralığı ise 19-85 arasındaydı. Cinsiyet, yaş, pnömatizasyonun lokalizasyonu ve lökularitesi kaydedildi.

Bulgular: Yaş ortalaması 34.4 olan 19 hastada (%1.9) PAE bulundu. 12 hasta kadın, 7 hasta erkekti. Cinsiyet ile PAE varlığı arasında istatistiksel olarak anlamlı fark bulunmamıştır (p>0.05). 12 unilateral ve 7 bilateral vaka gözlendi. Dokuz hastada (%47.4) sol tarafta PAE, üç hastada (%15.8) sağ tarafta PAE vardı. Yedi hastada (%36.8) uniloküler görünüm, 11 hastada (%57.9) multiloküler görünüm bulundu. Bir hastada (%5.3) hem uniloküler hem de multiloküler tip vardı.

Sonuç: Bu anatomik varyasyonu bilmek, diğer lezyonlardan ayırıcı tanı koymak ve ayrıca temporomandibular eklem ameliyatını planlamak için önemlidir. PAE bulunan kemiğin frajil yapısı nedeniyle, cerrahlar temporomandibular eklem operasyonlarında dikkatli olmalıdırlar.
