More than just tissue diagnosis in a patient with maxillofacial bony lesions and hypercalcemia.

Brown tumors are a definitive feature of hyperparathyroidism. They are well-demarcated osteolytic lesions commonly in the appendicular skeleton. Primary hyperparathyroidism is typically suggested by hypercalcemia and hypophosphatemia on routine labs.

Partial auricular reconstruction.

The authors summarize current methods for reconstructing partial auricular defects resulting from trauma, neoplasm, or congenital defects. They also review the anatomy and embryology of the ear as this is critical for proper reconstruction. Defects of the auricle are divided into upper-third, middle-third, and lower-third defects.

Functional reinnervation of vocal folds after selective laryngeal adductor denervation-reinnervation surgery for spasmodic dysphonia.

Selective laryngeal adductor denervation-reinnervation surgery (SLAD-R) offers a viable surgical alternative for patients with adductor spasmodic dysphonia refractory to botulinum toxin injections. SLAD-R selectively denervates the symptomatic thyroarytenoid muscle by dividing the distal adductor branch of the recurrent laryngeal nerve (RLN), and preventing reinnervation, by the proximal RLN and maintaining vocal fold bulk and tone by reinnervating the distal RLN with the ansa cervicalis. We present a patient who had previously undergone successful SLAD-R but presented 10 years postoperatively with a new regional dystonia involving his strap muscles translocated to his reinnervated larynx by his previous ansa-RLN neurorraphy.

Brachytherapy-mediated bone damage in a rat model investigating maxillary osteoradionecrosis.

Objectives: To assess clinical and radiologic findings from targeted radiotherapy to the rat maxilla and to compare findings with a recently developed rat model of mandibular osteoradionecrosis (ORN).

Design: A prospective, controlled animal study.

Subjects: Ten male Sprague-Dawley rats were divided into an experimental group receiving catheter-assisted high-dose-rate brachytherapy (n = 6) and a control group with catheter-assisted sham therapy (n = 4).
