Ultrasonography combined with FNA is a highly accurate technique for the investigation of cervical lymph node metastases. A more accurate diagnosis may result in more appropriate treatment, particularly in a setting with limited resources. Retropharyngeal nodes, micrometastases, and lymph nodes smaller than 4 mm are limitations of US-FNA. Ultrasonography combined with FNA is a useful technique for the staging of head and neck cancer.

A case of subperiosteal temporal abscess of otitic origin is presented. This is an unusual complication of otitis media. The pathogenesis of Luc's abscess is different from other extracranial complications of middle-ear infections in that it is notassociated with mastoid infection which results in subperiosteal pus formation. Based on our experience and the reports from the turn of the century. we present the presumptive pathogenesis and clinical features. We contend that these patients run an unexpectedly benign course, and require concomitantly more conservative treatment than other otitic abscesses.
