Transection of Nasolacrimal Duct in Endoscopic Medial Maxillectomy: Implication on Epiphora.

Objective: Management of the nasolacrimal system is usually recommended during medial maxillectomy via external approach because of reported higher rates of postoperative epiphora. Association of the endoscopic medial maxillectomy (EMM) with epiphora, however, is not clearly stated. In this study, we attempted to evaluate whether patients develop epiphora after simple transection of the nasolacrimal duct during EMM.

Prevertebral space invasion in head and neck cancer: negative predictive value of imaging techniques.

Objective: This study evaluated the diagnostic value of magnetic resonance imaging (MRI) and computed tomography (CT) in prevertebral space invasion in patients with head and neck squamous cell carcinomas (HNSCC).

Subjects And Methods: This study retrospectively reviewed 197 patients with advanced primary laryngeal or hypopharyngeal carcinoma who underwent laryngectomy and neck dissection at our institution. The MRI and CT findings were compared with the surgical findings and postoperative pathology.
