Traditionally, systemic chemotherapy has been the main form of treatment for recurrent squamous carcinoma of the head and neck. Unfortunately, response rates are seldom higher than 20-30%, with median survival times of 6-8 months. This paper explores the emerging role of reirradiation in the setting of recurrent squamous cell carcinoma of the head and neck; it reviews the existing literature focusing on radiation alone in this setting, and more recent literature integrating systemic radiosensitizing cytotoxics with reirradiation. Data from recent series using fluorinated pyrimidines and hydroxyurea, as well as platinating agents and taxanes, suggest occasional longterm survival benefits that exceed the historic norm. These approaches, largely confined to single institutions or small consortiums to date, are being evaluated prospectively in the cooperative group setting.

Background: Head and neck squamous cell carcinoma (HNSCC), a highly invasive malignancy with a poor prognosis, is one of the most common cancers globally. Circular RNAs (circRNAs) have become key regulators of human malignancies, but further studies are necessary to fully understand their functions and possible causes in HNSCC.
Methods: CircCCT2 expression levels in HNSCC tissues and cells were measured via qPCR.

Purpose: There are challenges in understanding the biomechanics of the human middle ear, and established methods for studying this system show significant limitations. In this study, we evaluate a novel dynamic imaging technique based on synchrotron X-ray microtomography designed to assess the biomechanical properties of the human middle ear by comparing it to laser-Doppler vibrometry (LDV).
Methods: We examined three fresh-frozen temporal bones (TB), two donated by white males and one by a Black female, using dynamic synchrotron-based X-ray microtomography for 256 and 512 Hz, stimulated at 110 dB and 120 dB sound pressure level (SPL).

Speechreading-gathering speech information from talkers' faces-supports speech perception when speech acoustics are degraded. Benefitting from speechreading, however, requires listeners to visually fixate talkers during face-to-face interactions. The purpose of this study is to test the hypothesis that preschool-aged children allocate their eye gaze to a talker when speech acoustics are degraded.

Purpose: Chemoradiotherapy (CRT) for head and neck cancer (HNC) often causes dysphagia. The risk of dysphagia increases during CRT tends to become more severe after finishing CRT, and persists for a few weeks thereafter. Thus, understanding the changes in swallowing physiology during and immediately after CRT is essential.
