Sarkoidoza woreczka łzowego jako przyczyna niedrożności dróg łzowych

Sarcoidosis is a systemic granulomatous disease of unknown aetiology. The course of sarcoidosis ranges from asymptomatic to severe. It could affect people of all ages. The disease affects predominantly the lungs and lymph nodes, skin, abdominal organs or eyes. Sarcoidosis of lacrimal sac is very uncommon. We describe a young man with lacrimal sac and nasal mucosa sarcoidosis present with epiphora. Few years before the onset of dacriocystitis the patient was treated because of lymph nodes sarcoidosis. The lacrimal sac sarcoidosis developed five years after systemic disease remission. An endoscopic dacriocystorhinostomy with intubation of nasolacrimal duct was performed. We used postoperatively systemic and local steroids for 3 months period. The patient is under observation for over four years with good health. The abnormal looking nasal or lacrimal sac mucosa could be associated with granulomatous disease as sarcoidosis and Wegener's or malignancies. If the sarcoidosis is established, it could be the first manifestation of sarcoidosis leading to future systemic sarcoidosis development or it may develop many years after the onset of systemic disease. Endoscopic dacriocystorhinostomy with intubation followed by intensive therapy with systemic and local corticosteroids may be helpful to maintain lacrimal drainage patency.

Orbital Perineurioma in the Setting of Dacryocystitis

A benign orbital perineurioma was discovered just posterior to the lacrimal sac during surgery for recurrent bacterial dacryocystitis in an 83-year-old woman. The tumor was circumscribed but nonencapsulated and located exterior to the lacrimal sac mucosa. It was composed of cytologically bland spindle cells organized in graceful, elongated, and twisted bundles reminiscent of a storiform pattern. Immunohistochemical staining displayed a diagnostic pattern of Claudin-1, GLUT-1, and epithelial membrane antigen positivity. Malignant transformation is virtually unknown, even with incomplete excision. The differential diagnosis includes neurofibroma, schwannoma, leiomyoma, solitary fibrous tumor (CD34 positive), and low-grade fibromyxoid sarcoma.

Comparison of surgical outcomes of endonasal dacryocystorhinostomy with or without mucosal flaps

Objective The goals of this study were to evaluate the long-term results of endoscopic endonasal dacryocystorhinostomy (DCR) with or without a posterior mucosal flap and to compare the surgical success rates of that procedure in patients with a nasolacrimal duct obstruction. Patients and methods We retrospectively investigated the results of 78 endoscopic endonasal DCRs performed at the Baskent University, Department of Otolaryngology between December 2000 and March 2007 on 74 patients with a lacrimal obstruction. The patients were divided into two groups. During surgery, the posterior mucosal flap was preserved in 27 patients (group A) and removed in 47 patients (group B). All patients underwent intubation with a silicone tube at the conclusion of surgery. The silicone tube was removed within 6 months after surgery. The mean follow-up period was 36 months (range, 2–78 months). The results obtained were then compared. Results Granulation tissue and synechia developed between the lateral nasal wall and the middle turbinate in one patient in group A (revision surgery was not required). In group B, granulation tissue at the rhinostomy opening was found in seven patients, and in four of those subjects, the granulation tissue obstructed the neo-ostium. These four patients underwent a second operation. In group B, synechia was noted between the middle turbinate and the lateral nasal wall in two of 47 patients. In group A, the procedure was successful for all patients except one in whom granulation tissue developed, and in group B, the surgical success rate was 88.3%. Conclusion In endoscopic endonasal DCR, the closure of bare bone with a posteriorly based nasal mucosal flap that creates an anastomosis between the lacrimal sac mucosa and the nasal mucosa decreases the formation of granulation tissue. But, there is no significant difference of success rate between two groups.

Lacrimal sac removal made easy by methylene blue in endoscopic dacrocystorhinostomy

Endonasal dacrocystorhinostomy (DCR) has gained interest in the last decade. Especially when a novice surgeon is performing the surgery, difficulty in identification of the lacrimal apparatus may complicate the procedure. We investigated the efficacy of methylene blue (MB) solution as a marker for lacrimal sac (LS) in endoscopic DCR. A total of 24 endoscopic DCR cases were performed (16 primary and 8 revision cases). During surgery, LS was irrigated with MB solution. Following lacrimal bone removal, medial wall of the LS is seen with a bluish hue. When the sac is dissected, the epithelium of the LS, which is heavily stained with MB contrasts with the surrounding nasal mucosa and therefore tailoring of the extent of the LS mucosa removal is facilitated. The follow-up period of the patients was 23 +/- 7.5 months. Of the 24 cases operated, only one case needed a re-operation. Use of MB solution is effective in both identifying LS and distinguishing it from surrounding nasal mucosa in DCR.

Pyogenic granuloma of the lacrimal sac

In this report, we describe three adult patients diagnosed with lacrimal sac pyogenic granuloma. The presenting symptoms were acute dacryocystitis, lacrimal mass, and bloody tears. The nasolacrimal drainage pathway was obstructed in all cases. Radiologic evaluation performed in one patient revealed the presence of a well-defined mass in the sac with homogenous contrast uptake. Histopathologic examination revealed capillary proliferation and inflammatory cells in a fibromyxoid stroma. The patients were followed up for 11-23 months after external dacryocystorhinostomy without recurrence of the tumor or nasolacrimal obstruction. Pyogenic granuloma may develop from the lacrimal sac mucosa and may cause bloody epiphora. Such a tumor is visualized as a hemorrhagic mass lesion, and it may not have a negative effect on the outcome of DCR.

Clinical Results of Endoscopic Dacryocystorhinostomy using a Microdebrider

PurposeThe success rate of endoscopic dacryocystorhinostomy has been increasing with the development of better instruments and techniques. We conducted this study to evaluate the clinical results of endoscopic dacryocystorhinostomy using a Microdebrider, which has also been used for functional endoscopic sinus surgery.MethodsWe selected 76 patients (with a total of 84 affected eyes) who had been diagnosed with a nasolacrimal duct obstruction. These patients underwent an endoscopic dacryocystorhinostomy using a Microdebrider, which removed both nasal mucosa and lacrimal sac mucosa and also trimmed the margins of the ostotomy site. We assessed patients' outcomes on an anatomical basis using a dye test and endoscopy, which were used to define the anatomical success. We also arbitrarily defined functional success as whether the subjective epiphora was absent. At a four to 18 month follow-up, we monitored the clinical course to examine any recurrent episodesResultsThe symptoms were alleviated in 72 eyes, with a primary success rate of 85.7%. On nasal endoscopy, a functional failure was seen in four eyes. In these four eyes, the orifice was narrowed by the presence of either granulation tissue or conjunctivochalasis. By contrast, surgical outcomes were the anatomical failure in eight eyes. In these eight eyes, the orifice was obstructed by the presence of granulation tissue as well as the adhesion of nasal mucosa.ConclusionsEndoscopic dacryocystorhinostomy using a Microdebrider enabled us to make the large fistula while minimizing the damage of adjacent tissue. It might be the recommended surgery that reduces the complications and enhances the success rate.

Dacriocistite crônica secundária a sarcoidose: relato de caso

A case of chronic dacryocistitis secondary to sarcoidosis is described. Review of the clinical pathological findings and surgical technique used to treat the patient. Dacryocystorhinostomy with silicone intubation on the left side was performed. Biopsy specimens of lacrimal sac mucosa showed a histological findings compatible with sarcoidosis, an uncommon diagnosis.

Agger nasi cell mucosal autograft for lacrimal sac reconstruction during endonasal dacryocystorhinostomy

A mucosal autograft composed of agger nasi cell mucosa was used to reconstruct the lacrimal sac mucosa in a young woman with a cicatrised lacrimal sac and obstructed nasolacrimal system. The patient had undergone a previous external dacryocystorhinostomy (DCR), dacryocystectomy and revision mechanical endonasal DCR. There was persistent epiphora and at further mechanical endonasal (MEN) DCR it was noted that only a small cuff of lacrimal sac mucosa around the common canaliculus was present. To achieve a mucosal anastomosis, the agger nasi cell mucosa was removed from the cell and placed as a free mucosal graft around the common canalicular opening. Apposition with the nasal mucosa was completed with flaps from the lateral nasal wall mucosa. Postoperatively, the patient is asymptomatic with a freely draining ostium at 18 months of follow-up.

Mechanical Endonasal Dacryocystorhinostomy Versus External Dacryocystorhinostomy

To compare the success rates of a new mechanical endonasal dacryocystorhinostomy (MENDCR) technique and the conventional external dacryocystorhinostomy technique (Ext-DCR). A prospective, nonrandomized interventional comparative case series of 31 consecutive MENDCRs and 24 Ext-DCRs performed from January 1999 to December 2000. Patients with anatomic nasolacrimal duct obstruction were included in the study; previous lacrimal surgery and functional nasolacrimal and canalicular obstruction were exclusion criteria. Two surgeons performed the MENDCRs, using a standardized operative technique, which involved creation of a large bony ostium and mucosal flaps between the lacrimal sac mucosa and nasal mucosa. One surgeon performed all Ext-DCRs. Twenty-seven patients (8 men, 19 women) underwent 31 MENDCRs. The average age of the patients was 62.9 years (range, 15 to 86 years; SD, 19.1 years). In 11 cases (35.4%), a septoplasty was required at the time of surgery, and in 6 cases (19%), further endoscopic sinus surgery was performed. In the Ext-DCR group, 23 patients (7 men, 16 women) underwent 24 DCRs. The average age was 59.6 years (range, 22 to 86 years; SD, 18.5 years). No other nasal procedures were performed at the time of surgery in this group. The average follow-up time was 13 months for the MENDCR group and 12.4 months for the Ext-DCR group. Success was defined as relief of symptoms and by anatomic patency, which was assessed by history, fluorescein flow on nasal endoscopy, and lacrimal syringing. In the MENDCR group, surgery was successful in 29 of 31 DCRs (93.5%); 1 of 2 failed cases was anatomically patent but symptomatic, yielding an anatomic patency rate of 96.8%. In the Ext-DCR group, the success rate was 95.8% (23/24 DCRs); the failed case was anatomically patent but symptomatic, giving an anatomic patency rate of 100%. The differences in overall success and anatomic patency were not statistically significant (P = 0.6 and P = 0.56, 1-tailed Fisher exact test). The success rate of MENDCR (93.5%) compares favorably with that of standard external DCR (95.8% in this study). MENDCR relies on the creation of a large ostium and mucosal flap apposition. A larger, randomized prospective trial is needed to fully assess the efficacy of this new technique.

Endonasal dacryocystorhinostomy with mucosal flaps

PurposeTo describe a new endonasal dacryocystorhinostomy (DCR) technique and assess its efficacy. DesignProspective nonrandomized interventional case series. MethodsA prospective series of 44 consecutive endonasal DCRs performed from January 1999 to December 2000 was entered into the study. The new technique involved creation of a large bony ostium and mucosal flaps to create an anastamosis between the lacrimal sac mucosa and nasal mucosa. Patients presenting with naso-lacrimal duct obstruction based on symptomatic, clinical, and radiologic grounds were included in the study. Patients who had undergone previous lacrimal surgery were excluded. Surgery was performed by two surgeons (A.T., P.J.W.) using a standardized operative technique. Patient demographics, presentation, examination findings, surgical and anesthetic data, postoperative success, complications, and follow-up were evaluated. Success was defined as anatomic patency as well as relief of symptoms as assessed by fluorescein flow on nasendoscopy, lacrimal syringing, and patient examination. Intubation of the lacrimal apparatus was performed in all operations and the tubes usually removed at 4 to 6 weeks postoperatively. After removal of the tubes follow-up was 13 months (mean, 12.9 months; range, 9–28 months; standard deviation [SD], 6.1 months). ResultsThere were 36 patients (12 male/24 female) who underwent 44 endonasal DCRs. The average age of the patients was 62.9 years old (range, 15–86 years old; SD, 19.1 years) and the main presentation was with epiphora (93%) and/or mucocoele (33%). In 13 operations (30%) a septoplasty was required at the time of surgery, and in 10 operations (23%) further endoscopic sinus surgery was performed in conjunction with the DCR. Anatomic success with a patent nasolacrimal system was achieved in 40 of 44 operations (91%). Symptomatic and anatomic success was seen in 39 of 44 operations (89%). Five of the DCRs were classified as failures. In one DCR the patient was symptomatic despite a patent nasolacrimal system and well-healed ostium. In two DCRs preoperative medial canalicular problems were noted. In two DCRs scarring and fibrosis of ostium were noted. ConclusionsThis new technique of endonasal DCR involves creation of a large ostium and construction of nasal and lacrimal sac mucosal flaps. Its anatomic success rate (91% or 40 of 44 DCRs) compares favorably with the success rate of other techniques for endonasal DCR and is also similar to the success of external DCR. Experience in endoscopic nasal surgery is important in endonasal DCR surgery, as other ancillary procedures may be required within the nose at the time of surgery.

The intranasal ostium after external dacryocystorhinostomy and the internal opening of the lacrimal canaliculi

The purpose of this paper was to evaluate the appearance and location of the healed intranasal ostium and the internal aperture of the common canaliculus after uncomplicated external dacryocystorhinostomy (DCR). In 21 patients who underwent uncomplicated external DCR, the distances between the lacrimal puncta and the internal aperture of the common canaliculus were measured during surgery. The measurements were taken with a 1 mm diameter Bowman probe graded in millimeters. These measurements were recorded and considered the landmarks for the spatial localization of the internal aperture of the canaliculus. After surgery, under endoscopic control, the same method was used to measure the distance between the lacrimal puncta and the internal ostium, which was defined as the aperture through which it was possible to visualize the very first protrusion of the probe into the nose. The intra- and post-operative measurements were compared. Endoscopic photos of the healed endonasal ostium were also taken. The photos showed that when DCR procedures were not complicated by scarring or mucosal adhesions, the lacrimal sac became a depression perfectly integrated within the nasal mucosa. The scar at the site of junction between the nasal and the lacrimal sac mucosa appeared as a large-diameter pearl-like colored frame that surrounded the depression. In the context of the depression a small aperture, which presented a diameter of around 2 mm, could be easily visualized. The spatial location of this aperture corresponded to the internal aperture of the common canaliculus (p < 0.05).

Lectin Cytochemistry of the Rabbit Conjunctiva and Lacrimal Sac

Four different types of lectin were applied to the rabbit conjunctiva and the lacrimal sac to examine the distribution of glycoconjugates. The conjunctival epithelium is comprised of goblet cells and nongoblet cells. The mucus granules of the goblet cells were stained with soybean agglutinin (SBA), and the cell body of the nongoblet cells was labeled with concanavalin A (Con A). The glycocalyx of the apical surfaces of the goblet cells and of the nongoblet cells was labeled with Maculura pomifera agglutinin. The lacrimal sac mucosa is comprised of superficial light and dark cells, and basal cells. The cell bodies of the light cells were stained with SBA. The glycocalyx of the apical surfaces of the light and dark cells was characteristically labeled with Con A. These results suggest that the composition of glycoconjugates is markedly different between the conjunctiva and the lacrimal sac, especially in the cell surface glycocalyx.

A histochemical and immunohistochemical study of certain defense mechanisms in the human lacrimal sac epithelium.

The mucosal surface of the human lacrimal sac represents an area exposed to exogenous agents including potentially harmful microorganisms. The human lacrimal sac was examined histochemically to identify glycoproteins, and immunohistochemically to identify secretory IgA. Neutral and acid glycoconjugates were detected mainly in the cytoplasm of the surface cells of the columnar stratified epithelial lining. The same reactions were recognized in occasional clusters of secretory cells forming intraepithelial glands in the lining of the lacrimal sac. The presence of secretory IgA in the cytoplasm of the apical epithelial cells was demonstrated. The results indicate that the lacrimal sac mucosa possesses certain active defense mechanisms against ascending infections.

Holmium: YAG Endonasal Laser Dacryocystorhinostomy

Previously described techniques of endonasal laser-assisted dacryocystorhinostomy appear to offer several advantages over conventional external dacryocystorhinostomy, including the following: (1) decreased disruption of medial canthal anatomy, (2) enhanced hemostasis, and (3) avoidance of a cutaneous scar. Although good results were achieved, several limitations of early laser-assisted techniques have been noted, including difficulty in removal of the thick bone of the anterior lacrimal crest and inability to obtain specimens of lacrimal sac mucosa for biopsy purposes. In a series of 40 consecutive, primary endonasal dacryocystorhinostomy procedures, we used the holmium:YAG (Ho:YAG) laser for bone removal and endoscopic sinus surgical instrumentation to obtain lacrimal sac biopsy specimens. Intraoperative hemostasis was excellent and medial canthal scarring was avoided in all patients. The overall long-term ostium patency rate in our series was 82%. Several technical modifications adopted in the latter part of our series, including use of a small drill for supplemental bone removal, extensive removal of lacrimal sac mucosa, and use of a double stent, appeared to enhance this success rate.

Dacryocystifis Associated with Malignant Lymphoma of the Lacrimal Sac

Tumors of the lacrimal sac are unusual, and lymphomas of the lacrimal sac are quite rare. Four patients with a history of well-differentiated, small cell lymphoma or chronic lymphocytic leukemia presented with either acute or chronic dacryocystitis and epiphora due to lymphomatous infiltration of the lacrimal sac. All four patients underwent dacryocystorhinostomy with lacrimal sac biopsy. All tissues underwent complete histopathologic evaluation including immunohistochemical studies for cell surface markers and, in addition, were compared with previous biopsies performed for the initial diagnosis of lymphoma. All biopsies demonstrated small cell well-differentiated lymphoma on histologic and immunofluorescent examination. No patient demonstrated orbital involvement on computed tomography. One patient had previously diagnosed chronic lymphocytic leukemia and one patient demonstrated diffuse lymph node involvement on postoperative systemic evaluation. All four patients underwent additional chemotherapy. No recurrence of dacryocystitis or epiphora occurred. Four patients presented with dacryocystitis secondary to lacrimal sac lymphoma. Lymphomatous lacrimal sac infiltration is an unusual cause of dacryocystitis. Biopsy of the lacrimal sac plays a diagnostically important role in dacryocystorhinostomy even in the absence of obvious tumorous involvement of the lacrimal sac mucosa.

Dacryocystorhinostomy utilizing an anterior lacrimal sac flap to periosteum technique.

Dacryocystorhinostomy is used in the effective treatment of epiphora secondary to obstruction of the lacrimal drainage system. Common causes of obstruction include canalicular disruption, lacrimal sac fibrosis, and external and internal nasal trauma. Most techniques of dacryocystorhinostomy attempt to suture the lacrimal sac mucosa to the nasal mucosa. At best this is technically difficult, and the mucosa frequently tears. A technique is presented using an anteriorly based lacrimal sac pedicle flap sutured to the periosteum of the anterior lacrimal crest. The sutured flap is quite strong, and the procedure is technically simpler than others. A brief description of the causes of lacrimal obstruction is given. The Jones primary and secondary dye tests for lacrimal system patency are reviewed.

The use of cautery in external dacryocystorhinostomy.

MANY ophthalmologists prefer not to perform external dacryocystorhinostomy, and some others perform the procedure so infrequently that the percentage of good results is discouraging. The purpose of this paper is to describe a simple diathermy technique which will increase the cure rate following this difficult operation. External dacryocystorhinostomy, performed in the routine manner, is more effective when the mucosal flaps are fashioned differently and cautery is used to enlarge the membranous anastomosis. Technique After a large amount of the bone which separates the lacrimal sac from the nasal mucosa has been removed, fashion flaps of the lacrimal sac mucosa and of the nasal mucosa so that they are hinged anteriorly and later can be sutured together. (In adults, the osseous anastomosis should be approximately 15 mm in diameter.) To enlarge the membranous anastomosis between the lacrimal sac and the nasal cavity, apply diathermy (high frequency voltage) (beginning about 2 mm
