“…CT scan tulang temporal sangat akurat untuk menunjukkan adanya jaringan abnormal di telinga tengah, dengan sensitivitas berkisar antara 70% hingga 96%, tetapi salah satu keterbatasannya ialah tidak dapat menentukan apakah jaringan tersebut inflamasi, fibrotik atau kolesteatoma. 10,11 Kolestatoma pada CT scan akan terlihat sebagai soft tissue mass pada telinga tengah yang disertai erosi atau destruksi tulang baik osikula, skutum, kanalis semisirkularis lateral ataupun tegmen timpani. Tanpa erosi atau kerusakan tulang, sulit untuk membedakan kolesteatoma dari jaringan granulasi atau cairan yang terkait dengan otitis media kronis.…”

“…Adanya erosi tulang pada beberapa struktur seperti osikula, tegmen timpani, scutum, dan kanalis semisirkularis, sangat mengindikasikan kolesteatoma pada suatu otitis media kronis. 10,11 Pada penelitian ini, peniliaian kolesteatoma melalui CT scan tulang temporal preoperatif pada total 54 sampel berdasarkan adanya densitas jaringan lunak telinga tengah disertai erosi tulang. Berdasarkan kriteria tersebut, 17 dari 20 sampel penderita kolesteatoma yang berhasil dinilai dari CT scan tulang temporal.…”

This study was aimed to determine the accuracy of preoperative temporal bone CT-scan ini assessing cholesteatoma in chronic suppurative otitis media (CSOM) patients. This was a diagnostic test study conducted by comparing the findings of the preoperative temporal bone CT-scan with the intraoperative findings of 54 CSOM patients who had a temporal bone CT-scan followed by surgery at the Hasanuddin University Hospital and the Jaury Academic Hospital. Assessment of cholesteatoma on a preoperative temporal bone CT-scan was performed when soft tissue density was found in the middle ear accompanied by bone erosion. In addition, an assessment was also carried out for the presence of ossicular, scutum, tympanic tegmen, facial nerve canal and mastoid tegmen erosions. The results indicated that the accuracy of preoperative temporal bone CT-scan in assessing cholesteatoma in CSOM patients was 87.04% with a sensitivity of 85%, specificity of 88.23%, a positive predictive value of 80.95%, and a negative predictive value of 90.91%. The sensitivity of the preoperative temporal bone CT-scan in assessing the highest erosion of cholesteatoma in the erosion of the scutum and tympanic tegmen (100%) with the specificity and accuracy of the preoperative temporal bone CT scan of the in assessing erosions in cholesteatoma highest on mastoid tegman erosion (100% and 96.29%). In conclusion, preoperative CT scan of temporal bone has high accuracy, sensitivity, and specifity values in assessing cholesteatoma and erosions of surrounding structures.Keywords: cholesteatoma, chronic suppurative otitis media (CSOM), temporal bone CT-Scan Abstrak: Penelitian ini bertujuan untuk mengetahui akurasi gambaran CT-scan tulang temporal preoperatif dalam menilai kolesteatoma pada penderita otitis media supuratif kronis (OMSK). Jenis penelitian ialah uji diagnostik yang membandingkan temuan pada CT scan tulang temporal preoperatif dengan hasil temuan intraoperatif pada 54 penderita OMSK yang menjalani pemeriksaan CT scan tulang temporal dilanjutkan dengan tindakan operasi di Rumah Sakit Universitas Hasanuddin dan Rumah Sakit Akademis Jaury. Penilaian kolesteatoma pada CT Scan tulang temporal preoperatif ketika ditemukan densitas jaringan lunak di telinga tengah yang disertai dengan erosi tulang. Selain itu, dilakukan penilaian adanya erosi osikula, skutum, tegmen timpani, kanalis nervus fasialis, dan tegmen mastoid. Hasil penelitian mendapatkan akurasi CT scan tulang temporal preoperatif dalam menilai kolesteatoma pada penderita OMSK sebesar 87,04% dengan sensitivitas 85%, spesifisitas 88,23%, nilai prediksi positif 80,95%, dan nilai prediksi negatif 90,91%. Sensitivitas CT scan tulang temporal preoperatif dalam menilai erosi pada kolesteatoma tertinggi pada erosi skutum dan tegmen timpani (100%) dengan spesifisitas dan akurasi CT scan tulang temporal preoperatif dalam menilai erosi pada kolesteatoma tertinggi pada erosi tegmen mastoid (100% dan 96.29%). Simpulan penelitian ini ialah CT scan tulang temporal preoperatif memiliki nilai akurasi, sensitivitas, serta spesifisitas yang cukup tinggi dalam menilai kolesteatoma serta erosi pada struktur di sekitarnya.Kata kunci: kolesteatoma, otitis media supuratif kronis (OMSK), CT scan tulang temporal

“…A erosão do canal semicircular é notada por ser muito frequente nos exames de imagem, mas nem sempre confirmada cirurgicamente. O sinal (ou mancha) de Schwartz é o único que não se manifesta no colesteatoma, uma vez que ele é característico da observação de tímpanos com otosclerose em atividade (ÁVILA et al, 2013;PAÇO;BRANCO, 2010; 10. A resposta é a).…”

“…False-positive reported cases in the literature that affect specificity and the PPV includes Silastic sheets, bone pâté (Muhonen et al, 2020), cartilage (Muhonen et al, 2020), OM (Mateos-Fernández et al, 2012), external canal cerumen, cholesterol granuloma, hemorrhage following a recent surgery, granulation tissue, and abscess (Fan et al, 2019;Lingam et al, 2016). On the other hand, false negatives may occur if cholesteatomas lose their keratin content due to recent procedures, in some cases (Baráth et al, 2011;de Ávila et al, 2013).…”
