lacrimal sac removal

 

If possible, treatment of secondary stenosis is primarily treatment of the cause (immunosuppressive therapy for granulomatous diseases, reduction of topical glaucoma treatment, and treatment of canaliculitis). 13 The parents should be informed about the possibility of minor bleeding from the nose or the puncta. 15.8 A patient with a posttraumatic bicanalicular stenosis and telecanthus formation following multiple surgical procedures on the lacrimal duct system. We didn't pay much attention to it till she started going to school. Once the periosteum is reached, the direction of the probe is changed downward, laterally and posteriorly, following the course of the nasolacrimal duct. Puncta – These are the small orifices present at the beginning of the canalicular ducts and are known as puncta lacrimalia. DCR (dacryocystorhinostomy) Due to the high rate of spontaneous remission when the clinical course of the disease is uncomplicated, the general recommendation is to postpone surgical intervention until the child is 1 year old and instead perform Crigler massage. In very rare cases, unintended injury to the angular vein may cause a copious amount of bleeding. 20,​ 32 Balloon dilation. Newborns make a light massage area of the lacrimal sac and nasopharyngeal canal to eliminate the blockage of the canal. The lacrimal sac had chronic inflammatory changes in 33 of 37 patients with varying degrees of fibrosis in 34 of 37. It consists of the puncta, canaliculi, lacrimal sac, and the nasolacrimal duct. 15.2). After the probing, a silicone stent is inserted into the lacrimal passage. (b) After contact with the periosteum, the probe’s direction is turned toward the first premolar tooth. If this is unsuccessful, prompt probing of the lacrimal duct is recommended in order to avoid neonatal dacryocystitis. The prevalence of symptomatic acquired stenoses is reported in a US cohort study as ~30 per 100,000 inhabitants. The immediate regurgitation of clear liquid via the opposite punctum occurs with common canalicular block (CCB), the delayed regurgitation, sometimes associated with mucoid flakes or pus, is indicative of NLDO. Treatment options are: This test is particularly useful in children, since diagnostic syringing usually cannot be done. Particularly in children, silicone can lead to granuloma formation in the area of the puncta or in the nasolacrimal duct. canaliculus and lacrimal sac, thus securing the stent’s fixation. (c) Position of the LJT anterior to the attachment of the middle nasal concha without contact with the nasal septum (arrow, distal edge of the LJT). It consists of three parts: mucin, water, and lipid, which are produced by the lacrimal gland, the lids, and the outer surface of the eye respectively. An abscess should be punctured with a small cannula and the fluid obtained should be sent for microbiological analysis including an antibiogram. The prevalence of primary canaliculitis is unknown; Estimates suggest 2% – 4% of the patients in an ophthalmic practice have symptoms associated with canaliculitis. 15.1.3 Congenital NLDO Mono- and bicanalicular silicone intubation systems are available for this; the success rate is independent of the type of intubation. A blockage of the lacrimal drainage system can be classified by the anatomical localization and the degree of stenosis (absolute or relative). Anomalies such as punctum or canalicular atresias as well as lacrimal sac fistulas are rare causes of infantile epiphora. Syringing is performed through either the upper or the lower lacrimal punctum. In such cases, a dacryocystectomy may have impact on visual rehabilitation. 15.5b), for example, after rubbing in the medial canthus, can necessitate early removal of the tube and thus endanger the success of the treatment. In our view, balloon dilation can be tried as next choice to avoid a DCR. Postoperatively, topical antibiotics and nasal decongestants are given. It is more physiological and significantly less invasive than DCR. A blunt pair of scissors is now inserted horizontally and the periosteum of the lateral nasal wall is exposed via blunt dissection. Fig. The accumulation of tears due to insufficient drainage is referred to as epiphora. Distal canaliculus 31 The use of Jünemann or Ritleng probes or the flexible Crawford probe for lacrimal intubation, along with careful probing, helps in minimizing of these complications. Addeo Toti first described the DCR procedure in 1904. Most authors report a success rate of 90 to 95%. Moffet’s solution contains epinephrine, cocaine, and bicarbonate as local vasoconstrictors and anesthetics. (In collaboration with Dr. L. Bauer, Department of Otorhinolaryngology, Head and Neck Surgery, Nordstadt Clinic, Hannover, Germany. A significant laxity is present if repositioning is delayed, if it requires blinking, or if there is no apposition to the eyeball at all. Therapeutic probing and syringing of the lacrimal system. The instrument normally slides on its own with the use of soft pressure in the appropriate direction. 13 Some authors report that the rate of spontaneous canalization decreases with increasing age of the child. Complications of NLDO include acute dacryocystitis (possibly with empyema formation), which may lead to orbital cellulitis or sepsis if left untreated ( ▶ Fig. The suture remains as a splint for the silicone tube. Postoperative medication with oxymetazoline nose drops and eye drops and antibiotic eye drops (e.g., azithromycin, kanamycin) for a week is recommended. A reflux of fluid via the same lacrimal punctum is an indicator of a canalicular stenosis. (d) Deep stenosis of lacrimal sac Dacryocystography: the level and severity of stenosis, identification of fistulae or tumors, ENT examination: exclusion of local obstructions e.g. 25 With a normal dye disappearance test it can be removed earlier to avoid complications. I was really very frustrated as it was difficult to keep eyes, I met many plastic surgeons in the New York area for my rhinoplasty but was not convinced about their attention to detail and aesthetic bent of mind. (b) Canaliculus communis stenosis. ROPLAS is an initialism for “regurgitation on pressure over the lacrimal sac”. The probe is stopped by the bone of the lacrimal sac fossa. If this treatment is unsuccessful, a dacryocystorhinostomy should be carried out where necessary a few days later. 15.2 Flowchart for the clinical diagnosis of lacrimal duct stenosis. The clinical examination starts with the inspection of the eyelids and of the periocular region (see Chapter ▶ 3.1). 19 Furthermore, the probability of developing acute dacryocystitis increases with the duration of the stenosis and reduces the success of probing. NLDO in combination with common canalicular block produces an accumulation of trapped mucous in the dilated lacrimal sac, which is termed mucocele. Treatment Draining of the lacrimal sac is prevented by the obstruction in the area of the Rosenmüller and Hasner valves. 42,​ 43 According to a meta-analysis, silicone intubation seems to have no influence on the patency of a primary DCR. Revision surgery can be done in case of failure. In bony stenosis, repeated re-stenosis, or recurrent dacryocystitis, a dacryocystorhinostomy has to be done. 15,​ 16, There has been increasing discussion whether an earlier surgical intervention from the age of 6 months can be recommended. After the probing, a silicone stent is inserted into the lacrimal passage. Once the periosteum is reached, the direction of the probe is changed downward, laterally and posteriorly, following the course of the nasolacrimal duct. DCR (dacryocystorhinostomy) The examination of the nose has the advantage that the surgery can be combined, if necessary, with a medialization of the inferior nasal concha, should the latter obstruct the ostium. The lacrimal drainage system is made up of the puncta, canaliculi, lacrimal sac and the nasolacrimal duct. The hollow tube is placed onto the punctual end of the suture and drawn into the nose. Women have a narrower nasolacrimal duct than do men. The patency of the lacrimal system can either be confirmed directly by irrigation (the patient in analgosedation swallows spontaneously; in general anesthesia flushing can be performed using fluorescein solution and can be detected in the nose as in the Jones test) or by means of nasal endoscopy. (In collaboration with Dr. L. Bauer, Department of Otorhinolaryngology, Head and Neck Surgery, Nordstadt Clinic, Hannover, Germany.) Amritsar, Punjab 143001, Apollo Spectra Hospital, Some authors recommend packing the nose with 4% cocaine or oxymetazoline to minimize intraoperative bleeding and for a planned nasal endoscopy. If this is unsuccessful, prompt probing of the lacrimal duct is recommended in order to avoid neonatal dacryocystitis. 44. 15.6a). When this is suspected, the probe can be withdrawn and a new attempt made to push forward. Trephination A false passage can be avoided by using the correct probing technique. At the beginning of the surgery, a nasal pack with Moffet’s solution is inserted into the nose near the location of the ostium at the insertion of the middle turbinate. If the test is negative, the lacrimal ducts are flushed with saline (Jones II). If no dye can be detected, this either means an absolute or a canalicular stenosis, as there is no accumulation of fluorescein in the lacrimal sac. The tube is introduced into the nose via the ostium and knotted. The doctor removes a tiny piece of bone to allow drainage between the lacrimal sac and the nose. CDCR (conjunctivodacryocystorhinostomy) 25 With a normal dye disappearance test it can be removed earlier to avoid complications. Many authors in the United States and United Kingdom conduct this procedure as an “office procedure” without sedation, 21 but this can however only be done in children under 1 year of age. A frequently occurring anatomical variant of the ethmoidal cells are the so-called agger nasi cells, part of the ethmoid displaced anteriorly between lacrimal sac fossa and nasal cavity. General anesthesia is required for balloon dilation. 28 The success rate is 79 to 96%. I have 5 year old son who is the joy of my life. If this happens spontaneously and rapidly, there is no laxity. 2, 8–12 The treatment of choice is complete surgical removal. A case of lacrimal sac cyst is presented.
