1/14. Modified trabeculectomy incision for c ataract extraction.Preservation of the fistula site from previous filtering surgery for glaucoma at the time of cataract surgery is difficult. A modified trabeculectomy incision for cataract extraction following successful filtering surgery for glaucoma is described.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/14. Dentocutaneous fistula.Chronic dental infection is the most common cause of draining sinus tracts of the face and neck. These lesions can be a diagnostic challenge to the clinician who is not familiar with dentocutaneous fistula. diagnostic errors can result in multiple excisions, biopsies, and ineffective long-term antibiotic therapy. patients may require excision of the fistula once the dental abscess has been successfully treated by root-canal therapy or extraction. Nine patients are reported.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
3/14. Cutaneous sinus of dental origin: a diagnosis requiring clinical and radiologic correlation.Cutaneous sinuses may arise from chronic dental infections. These sinus tracts usually appear as suppurative lesions of the chin or neck. diagnosis is made by palpating the lesion and by radiologic examination demonstrating periapical dental abscess. Treatment with dental extraction or root canal results in resorption of the inflammatory fistula. Since many patients with sinus tracts of dental origin do not have any complaints of tooth or mouth pain, the correct diagnosis may be overlooked by the unsuspecting clinician.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
4/14. Staphyloma: a complication of surgery for hyphema.Anterior staphylomas developed in two young patients as a postoperative complication of hyphema extractions through corneoscleral sections. The patients, aged five and nine years, underwent evacuation of the hyphemas after rebleeding caused medically unmanageable intraocular pressure elevations. Postoperatively, both patients received corticosteroids and had elevation of intraocular pressure. To repair the staphyloma, a scleral overlay patch graft was performed in one patient, but the intraocular pressure remained elevated and the staphyloma gradually recurred. Enucleation of the eye was eventually required. Resection of the staphylomatous area with lensectomy and complete vitrectomy was performed in the second patient. After four years of follow-up this patient continues to do well.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
5/14. Reopening filtration fistulas with transconjunctival argon laser photocoagulation.Three patients (a 15-year-old girl, a 45-year-old woman, and a 61-year-old woman) with previously successful full-thickness filtering procedures developed pigmented tissue in the fistula sites and uncontrolled intraocular pressures despite maximum tolerable medical therapy. The filtering procedures in the first and second patients spontaneously failed two and four years after surgery. The filtration bleb of the third patient, after successfully controlling intraocular pressure for six years, failed two months after cataract extraction. argon laser therapy was applied through the conjunctiva to treat visible subconjunctival pigmented tissue within the sites of the previous surgical filtration blebs. In all three cases, there was an immediate and significant decrease in intraocular pressure associated with reestablishment of the filtration bleb (from 44 to 16 mm Hg in Case 1, from 40 to 15 mm Hg in Case 2, and from 25 to 12 mm Hg in Case 3). Long-term follow-up showed well controlled intraocular pressures without glaucoma medications (Case 1, 5 mm Hg after 18 months; Case 2, 17 mm Hg after one year; and Case 3, 9 mm Hg after five months).- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |

7/14. Prolonged hypotony following cataract extraction.Hypotony after intracapsular cataract extraction was prolonged in 3 eyes because cyclodialysis clefts were inadvertently formed. One eye became normotensive with the topical application of corticosteroid; 2 required surgical intervention.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
8/14. Bouveret's syndrome: a rare consequence of malignant cholecystoduodenal fistula.We report a case of duodenal gallstone obstruction, resulting from cholecystoduodenal fistula. Fistulization was associated with a repeat chronic inflammation and metastatic carcinomatous infiltration. The diagnosis was confirmed by ultrasonography, barium meal examination, and gastroscopy. An attempt at endoscopic extraction was unsuccessful and the patient was referred for operative therapy. We present a graphic algorithm for decision-making in Bouveret's syndrome.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
9/14. mediastinitis with fistula formation to the left main bronchus. A complication of wisdom tooth extraction.We describe a 23-year-old patient who after extraction of four wisdom teeth developed a descending necrotizing mediastinitis with a spontaneous fistula to the left main bronchus. Because of this fistula, treatment was limited to surgical drainage of the neck region and antibiotics. Recovery was uneventful.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
10/14. Catheterobronchial fistula due to vena cava superior thrombosis as a late complication of ventriculoatrial shunt.A case of a catheterobronchial fistula as a rare late complication of a ventriculoatrial shunt is reported. The ventriculoatrial shunt was implanted in a 4-month-old boy suffering from extreme postinfectious hydrocephalus. During the following years, twelfth nerve palsy on the right, vertebralgias, and salty taste sensations in the mouth associated with intermittent coughing and swelling of the neck and supraclavicular region on the right side developed. Valvography established a diagnosis of fistula 12 years after the implantation of a shunt. ultrasonography of the neck and mediastinum and contrast-enhanced dynamic computed tomographic scanning demonstrated a catheterobronchial fistula to the subsegmental bronchus of the anterior segment of the right upper lung lobe, a thrombosis of the right internal jugular and both right and left brachiocephalic veins and the superior vena cava, and an extensive collateral venous system mainly draining into the azygos vein. Normalization of cerebrospinal fluid and blood flow and pressure allowed extraction of the "atrial" catheter without complications. One year after surgery the boys is in good health and without signs of shunt dependence.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
