Dacryocystorhinostomy*

PURPOSE: We studied whether the illumination had an influence on the identification of the location of the lacrimal sac and the success rate of endoscopic endonasal dacryocystorhinostomy (DCR). METHODS: Endoscopic endonasal DCR was performed on 85 eyes of 80 patients who had obstruction of nasolacrimal system without illumination. RESULTS: In all patients, identification of the location of the lacrimal sac by detecting the probe tip or the lacrimo-maxillary suture line was accomplished, without illumination. Final success rate was 87.1% in illuminator non-using group. CONCLUSIONS: We considered that endoscopic endonasal DCR without illumination, in the knowledge of lacrimal sac, ethmoid anatomy, and anatomical variations, was a non-invasive, efficient, and satisfactory method.

The study was carried out on 34 patients (6 males and 28 females) aged more than 16 years old who suffered from primary dacryocystitis and underwent endoscopic procedure with silicone intubation. All patients were followed up for clinical symptoms, had Jone’s test, and underwent endoscopy after 1, 3, 6, 9 and 12 months. Results: success rate was 94.44% after 6 months, and 93.75% after 12 months. There were not statistically significant differences to other authors. This procedure can be applied broadly in Vietnam

The study was carried out on 50 adults without physical defects and injuries in head, face, nose, eyes and cavity regions. The result: the height of lachrymal sac was 1.095± 0.036 cm, the width of lachrymal sac was 0.455± 0.020cm, the distance from the inferior turbinate to the lachrymal sac was 1.145± 0.030 cm and the distance from the anterior nasal spine to the lachrymal sac was 4.220± 0.010 cm. The anatomical landmarks in initial step have been applied on 30 patients. The surgery position is exactly determined, there is no mistake in any case, hurting neighboring areas is reduced, less bleeding, surgery and hospitalization time were shortened

Objective: To describe the cytopuncture microbiopsy (CM) technique performed during transcanalicular endoscopic lacrimal duct recanalization (TELDR) in patients with primary acquired nasolacrimal duct obstruction (PANDO) as an alternative to open biopsy, the standard method used in collecting specimen. Methods: This is a noncomparative, interventional case series with histopathologic correlation. Patients diagnosed with complete PANDO who underwent TELDR with balloon dacryoplasty and silicone intubation with CM at University of Santo Tomas Hospital from October 2014 to January 2017 were included. Results: Twenty (20) tissue specimens from the lacrimal sac and nasolacrimal duct were obtained from 18 patients. There were 16 females and 2 males included in the study. Mean age was 57.5 years. All specimens revealed few clusters of benign epithelial cells with few degenerated mononuclear cells and lymphocytes, and singly scattered lymphocytes that are set in fibrinous background. Tissue cytology studies were negative for malignant cells. Conclusion CM is a minimally invasive procedure that offers an alternative to open biopsy technique that can be done routinely during TELDR.

PURPOSE: To evaluate the internal ostium and lacrimal sac change after external dacryocystorhinostomy (DCR) using digital subtraction dacryocystography (DCG). METHODS: Between May 2003 and July 2004, digital subtraction DCG was performed to assess the ostium and lacrimal sac 6 months after external DCR in 48 patients (n=50 eyes). RESULTS: The lacrimal sac had reformed in 45 (90%) eyes. Mean ostium size was 2.4 mm (0.5~6.1 mm) and these were located at the inferior part of the reformed sac in 39 eyes (78%). Patients with a fistula-type internal ostium, of which the lacrimal sac had not reformed, often complained of epiphora (p=0.005). CONCLUSIONS: Digital subtraction DCG showed successful anatomic changes in the distal lacrimal pathway and confirmed that the internal ostium contracts into a relatively small ostium after DCR. A fistula-type internal ostium may explain the pathophysiology of functional failure after successful DCR.

The authors evaluated the effect of topical mitomycin-C on the prevention of dacryocystorhinostomy internal ostium obstruction as antifibroblastic adjuvant. Topical 0.02% mitomycin-C(MMC) eyedrop was applied postoperatively to conjunctival sac of 75 patients who underwent endoscopic dacryocystorhinostomy-MMC group. MMC was instilled twice a day from postoperative 1 day for 7 days and from postoperative 4th week for 7 days. Properly matched another 75 patients without postoperative adjuvant MMC were compared with MMC goup regarding endoscopic findings, patency rates and other eyedrop complications. The internal ostium were patent in 85% in MMC group, and 77% in MMC and control group, respectively. Endoscopic examination of internal ostium showed mean final diameter of 3.4mm in MMC group and 2.5mm in control. There were no significant complications in MMC group except delayed epithelialization of nasal mucosa which had no relationship with surgical outcome.
