A 31-year-old man with epiphora and mucous discharge from a traumatic lacrimal fistula underwent a computed tomographic dacryocystogram, revealing a fistula extending from the anterior ethmoid air cells through the lacrimal sac to the overlying skin with coexisting nasolacrimal duct obstruction. Endoscopic dacryocystorhinostomy enabled complete marsupialization of the lacrimal sac and agger nas...
The lacrimal gland secretes tear fluids to ocular surface, which plays an indispensable role in maintaining the health of the ocular epithelia and protecting the ocular surface from the external environment. The dysfunction of the lacrimal glands causes dry eye disease due to a reduction in tear volume. The dry eye disease is becoming a popular public disease, for the number of patients is incr...
Primary lacrimal sac lymphoma is rare. The common clinical features are epiphora and medial canthal swelling which mimic nasolacrimal duct obstruction. Histological examination is therefore important to avoid delay in diagnosis and treatment. We report a case of primary lacrimal sac lymphoma in a 72-year-old female who developed a metachronous tumour at the hard palate one year after excision o...
We present two patients with dacryoliths and patent lacrimal drainage with intermittent tearing and without infection. Dacryoliths can be present in the lacrimal sac or lacrimal duct without acute or chronic inflammation. In these cases, we believe dacryolith formation was a causative factor of intermittent epiphora even with a patent drainage system, and we propose that dacryoliths and even fu...
To apply the ultrasonic 3D reconstruction method to measure the anatomic image data of lacrimal sac in the normal adult Chinese population, providing imaging anatomical basis for the clinical diagnosis and treatment of lacrimal duct diseases. 80 volunteers without lacrimal duct diseases were enrolled. The GE Voluson E8 ultrasonic diagnostic apparatus was used, with gynecological intracavitary p...
Obstructions in the lacrimal pathways quite often require accurate and reliable image scanning for confirmation and documentation. Infrared thermal imaging, known as thermography, is a resource that complements diagnosis; it does not require touching the patient or applying contrast materials and has been used in various medical procedures for decades. However, there have been few studies in th...
PURPOSE To evaluate the necessity of draining more than one hepatic duct in malignant hilar obstructions. MATERIALS AND METHODS Two hundred seventeen self-expandable uncovered metallic stents (144 biliary Wallstents and 73 Memotherm nitinol stents) were placed percutaneously in 138 patients with unresectable malignant hilar obstructions. The patients included 76 men and 62 women, with a media...
A case of squamous cell carcinoma arising from the right lacrimal sac is presented. MR T2-weighted images showed a mass of low signal intensity in the right medial canthus extending into the nasolacrimal duct. This led us to postulate a high-grade malignant neoplasm arising in the lacrimal sac.
In traumatic lacrimal duct injury, stent placement and anastomosis are commonly performed soon after injury. However, selection for pediatric injuries has rarely been discussed. Herein, we present three cases (one 1-year-old two 3-year-olds; all patients were males) of injury discuss them along with a literature review. The site was the canaliculus in cases. Two treated nylon thread stents one ...
