“…In this pictorial review, we divided temporal bone lesions by location such as along the facial nerve, along the internal jugular vein, around the endolymphatic sac, in the internal auditory canal/cerebellopontine angle, petrous apex, middle ear, and mastoid, focusing on the imaging findings of temporal bone lesions. …”

“…Six additional external electrodes were used to record vertical and horizontal electrooculogram, as well as the signal from the left and right mastoid. EEG has been pre-processed, segmented in non-overlapping epochs, and independent component analysis (ICA) has been conducted to reject artifacts. …”

“…INTRODUCTION: Cholesterol granuloma is a benign mass that commonly involves the petrous apex but rarely affects other structures, such as the mastoid cavity. It is diagnosed histologically by the presence of giant cells, and Its management is individualized based on some factors such as the size and location of the lesion. …”

“…This study reports the use of a pedicled latissimus dorsi (LD) muscle flap to cover a large full-thickness scalp burn defect measuring 20 × 15 cm, including 15 × 13.7 cm of bone exposure and extending from the posterior neck to the mastoid and vertex of the scalp. The authors discuss the technique to safely maximize the reach, which includes distal dissection to the iliac crest and thoracolumbar fascia, dissection of the pedicle to the axillary vessels, tunnel creation through the pectoralis major muscle, re-attachment of the LD origin to the pectoralis major and teres major, and undermining of the neck skin and subcutaneous tissue to avoid damage of the accessory nerve. …”

“…According to the CT findings, total resection of cholesteatoma was possible by trans-canal atticotomy combined with the use of a rigid endoscope not only in 4 patients with the shadow localized in the epitympanum on preoperative CT scans but also in 18 out of 24 patients with the shadow extending from the epitympanum to the distal mastoid air cells. This study indicates that the trans-canal approach with endoscopic guidance is a useful technique for the treatment of cholesteatoma.…”
