Imaging Features of Malignant Lacrimal Sac and Nasolacrimal Duct Tumors.
The purpose of this study was to present the imaging features of primary and secondary malignant lacrimal sac and nasolacrimal duct tumors and their pattern of tumor spread in 18 patients. The most common tumor histology in our series was squamous cell carcinoma. In 15/18 patients, tumor involved both the lacrimal sac and duct at the time of diagnosis. In 11/16 patients on CT, the nasolacrimal ...
متن کاملCharacterization of mucins in human lacrimal sac and nasolacrimal duct.
PURPOSE Mucins are polymers that may reduce drag and enhance tear outflow. Mucin expression and distribution in human efferent tear ducts were tested in the physiological state, and potential differences in the expression pattern were investigated in the presence of primary acquired dacryostenosis (PANDO). METHODS Expression of mucins in human lacrimal sac and nasolacrimal ducts was monitored...
متن کاملModified endoscopic dacryocystorhinostomy with posterior lacrimal sac flap for nasolacrimal duct obstruction.
OBJECTIVES To evaluate a new technique of modified endoscopic dacryocystorhinostomy involving the creation of a large posterior flap at the lacrimal sac and to compare its success rate with that of the conventional endoscopic method of excising the entire medial lacrimal sac wall as a surgical treatment for epiphora caused by nasolacrimal duct obstruction. DESIGN Retrospective, interventional...
متن کاملApplied Endoscopic Anatomical Evaluation of the Lacrimal Sac
Introduction: Dacryocystorhinostomy (DCR), a popular surgical procedure, has been performed using an endoscopic approach over recent years. Excellent anatomical knowledge is required for this endoscopic surgical approach. This study was performed in order to better evaluate the anatomical features of the lacrimal apparatus from cadavers in the Isfahan forensic center as a sample of the Iranian ...
متن کاملThe efficacy of sleeve technique in primary nasolacrimal duct obstruction with a high lacrimal sac
PURPOSE To evaluate the efficacy of a sleeve technique during endoscopic dacryocystorhinostomy (DCR) in primary nasolacrimal duct obstruction (NLDO) patients with a high lacrimal sac. MATERIALS AND METHODS The medical records of 45 patients (49 cases) undergoing endoscopic DCR for primary NLDO with a high lacrimal sac were retrospectively reviewed. In 19 patients (21 cases), the thick maxilla...
