PURPOSE: To examine the surgical outcome of three-flap external dacryocystorhinostomy (3-flap ex-DCR) based on the most common site of granulation occurrence in no-flap endonasal DCR (no-flap en-DCR). METHODS: This was a retrospective observational study. We first examined the location of granulation occurrence in the osteotomy site using nasal endoscopy after no-flap en-DCR on 53 sides of 37 patients (5 male, 32 female) with nasolacrimal duct obstruction. Based on the results of this surgery, we performed 3-flap ex-DCR on 70 sides of 61 patients (18 male, 43 female) with nasolacrimal duct obstruction...

INTRODUCTION: The formation of a fistula between the lacrimal sac and the skin is a classic outcome of resistant lacrimal sac abscesses. There is currently no consensus about treatment in such cases. The goal of this study was to describe the natural history of acquired fistulas between the lacrimal sac and the skin, occurring before planned endonasal dacryocystorhinostomy (DCR) and without any treatment of the fistula. MATERIALS AND METHODS: This prospective study was only descriptive and included patients between 1999 and 2012...

Patients with conjunctival cicatrizing disease may develop lacrimal obstruction. Little is published on lacrimal obstruction as the presenting feature of otherwise asymptomatic cicatrizing conjunctival disease. The records of all patients presenting between 1994 and 2015 with lacrimal obstruction found to have cicatrizing conjunctival disease were reviewed. Demographic details, clinical findings, disease progression and treatment were analyzed. Thirty-five patients (25 female), aged 43-91 years (median 74, mean 71...

This article reports a presentation of lacrimal sac rhinosporidiosis and informs the reader of this uncommon but important diagnosis. A 36-year-old man from Pakistan presented with a 3-month history of swelling at the nasal aspect of the left lower lid. This was associated with occasional crepitus and slight localised discomfort, but no epiphora. There was a palpable fullness near the left medial canthus associated with telecanthus but a normal sac washout and normal eye examination otherwise. Previous medical history included an ipsilateral nasal polypectomy and inferior meatal antrostomy around 10 years previously, whilst living in Pakistan...

Solitary fibrous tumor (SFT) is an uncommon neoplasm that usually arises from the pleura. Recently, SFTs have been reported in the head and neck region located in subsites such as the orbit. SFTs of the lacrimal sac are extremely rare, with only six cases reported in the English literature. We describe a SFT arising from the right lacrimal sac and extending along the nasolacrimal duct into the nasal cavity. Although, the tumor could not be removed by endoscopic-modified medial maxillectomy (EMMM) alone, combined approach with EMMM and a small external incision achieved the complete removal of the tumor...

PURPOSE: We recently reported that isolated duct segments from rabbit lacrimal gland (LG) were able to secrete fluid in response to secretagogues, which were blocked completely by bumetanide. This suggests the functional involvement of Na+-K+-2Cl- cotransporter (NKCC1) in ductal fluid secretion. Therefore, the aim of this study was to investigate the activity profile of NKCC1 in isolated rabbit LG duct segments. METHODS: Interlobular ducts were isolated from fresh rabbit LG tissue...
