A silastic sheet found during endoscopic transnasal dacryocystorhinostomy for acute dacryocystitis.
(25/75)
PURPOSE: To report the case of a silastic sheet that was found during an endoscopic transnasal dacryocystorhinostomy for treatment of acute dacryocystitis with necrosis of the lacrimal sac. METHODS: A thirty-two year old male presented with painful swelling on the nasal side of his left lower lid two weeks prior to visiting this clinic. Fourteen years ago, the patient was involved in a traffic accident and underwent surgery to reconstruct the ethmoidal sinus. Lacrimal sac massage showed a regurgitation of a purulent discharge from the left lower punctum. Therefore, the patient was diagnosed with acute dacryocystitis and an endoscopic transnasal dacryocystostomy was performed the next day. RESULTS: The surgical finding showed severe necrosis around the lacrimal sac and a 20 x 15-mm sized silastic sheet was found crumpled within the purulent discharge. The sheet was removed, the lacrimal sac was irrigated with an antibiotic solution, and a silicone tube was intubated into the lacrimal pathway. After surgery, the painful swelling on the nasal side of left lower lid resolved gradually, and there were no symptomatic complications three months later. CONCLUSIONS: We report the first case where a silastic sheet applied during a facial reconstruction had migrated adjacent to the lacrimal sac resulting in severe inflammation. (+info)
Endoscopic dacryocystrhinostomy.
(26/75)
Endonasal endoscopic dacryocystorhinostomy (EN-DCR) is now a well-established procedure to relieve nasolacrimal duct obstruction, becoming its domain for the ENT surgeons indispensable. AIM: The aim of the present study is to report the experience of the Otorhinolaryngology Department of the University of Sao Paulo Medical School in the management of the obstruction of the drainage of the nasolacrimal system by EN-DCR, comparing with the results in literature. STUDY DESIGN: clinical retrospective. MATERIAL AND METHOD: We reviewed the medical records of 17 patients (17 eyes) that were submitted to EN-DCR between april 2001 and july 2004. We analysed: sex, age at the time of diagnosis, etiology, clinical findings, surgical technique, use of silicone tubes, follow-up and complications. RESULTS: Eight men and nine women, the age range was from 29 to 79 years (mean 42.6413.1 years), mean follow-up time: 15 months, presented a lacrimal clinic with epiphora. Powered DCR was performed in 06 cases and YAG LASER in 01 patient. Silicone tubes were used in all cases and left in place mean 7.9 weeks. The surgical success rate was 82,3%. CONCLUSION: EN-DCR showed one safe technique, with advantages in relation to the external technique. So ophthalmologists and ENT physicians must work in harmony to offer more benefits to its patients. (+info)
Endonasal dacryocystorhinostomy in children.
(27/75)
AIM: To verify whether our results with endonasal endoscopic dacryocystorhinostomy in children with nasolacrimal duct obstruction allow us to consider this technique a valid treatment alternative for children. STUDY DESIGN: clinical with transversal cohort. MATERIAL AND METHOD: Twenty-seven endoscopic endonasal dacryocystorhinostomies were performed in children 2 to 12 years of age for nasolacrimal duct obstruction. Previous probings in all patients were unsuccessful. The technique employed uncinectomy and a small lacrimal sac opening. Follow-up time was 3 months. RESULTS: Twenty-one surgeries (77,8%) were successful. The only complication was silicone prolapse in one case. CONCLUSION: Our results confirm endoscopic endonasal dacryocystorhinostomy as an acceptable and safe method for treating children with nasolacrimal duct obstructions that are resistant to probings.

Endoscopic dacryocystorhinostomy: creation of a large marsupialized lacrimal sac.
(28/75)
This retrospective study describes and evaluates the effectiveness of a modified technique of conventional endoscopic dacryocystorhinostomy (DCR) that minimizes the obstruction of a neo-ostium by creating an enlarged marsupialized lacrimal sac using mucosal flaps. Forty-two patients who had undergone 46 endoscopic DCR at a tertiary medical center, from 2002 to 2004, for correction of lacrimal system obstruction were investigated. The surgical technique involves elevation of a nasal mucosal flap, full sac exposure using a power drill, and shaping of the mucosal flap to cover denuded bone and juxtapose exposed sac mucosa. Postoperative symptoms and endoscopic findings of the neo-ostium were evaluated. Mean duration of follow-up was 5.9 months. An eighty-three percent primary success rate was observed, without any serious complications. Obstruction of the neo-ostium with granulation tissue was observed in eight cases, among which six underwent revision with success in all cases. Overall, 44 (96%) of 46 cases experienced surgical successes. Endoscopic DCR, a procedure in which a large marsupialized lacrimal sac is created from mucosal flaps, yields a very satisfactory success rate with straightforward and highly successful revision available for those in whom the primary procedure yields a substandard result.

Lacrimal excretory system sequelae in patients treated for leishmaniasis.
(29/75)
Leishmaniasis infection may involve destruction of nasal tissues resulting in lacrimal drainage system alteration. PURPOSE: To evaluate the frequency of lacrimal excretory system sequelae in patients treated for leishmaniasis. METHODS: Forty-five leishmaniasis-treated patients (90 nasolacrimal ducts) were submitted to lacrimal excretory system evaluation. All were evaluated by Jones I test and when it was abnormal, dacryocystography and nasal endoscopy were performed. This situation occurred in 13 patients (26 nasolacrimal ducts). RESULTS: The majority of evaluated patients had the cutaneous form (64.4%) of leishmaniasis, however, 69.23% of the patients with lacrimal excretory system alterations had the mucocutaneous form of infection before treatment. In these, the most common alteration detected was bilateral permeable and dilated nasolacrimal ducts (92.30%). Only 3.84% (1/26) of the evaluated nasolacrimal ducts were obstructed. Nasal endoscopy showed turbinate hypertrophy (53.84%), septum deviation (53.84%) and nasal septum perforation (23.07%). CONCLUSION: Permeable and dilated lacrimal excretory system were the most common sequelae related to leishmaniasis infection. (+info)
Dacryocystorhinostomy in patients lacking an ipsilateral nasal cavity.
(30/75)
Dacryocystorhinostomy (DCR) remains the surgery of choice for the treatment of epiphora secondary to nasolacrimal duct (NLD) obstruction. It involves creating a direct soft-tissue anastomosis between the lacrimal sac and the ipsilateral nasal cavity, via an osteotomy created by removal of the floor of the lacrimal fossa and surrounding bone. Successful surgery clearly requires the presence of a nasal space and absence of this poses a surgical challenge. We describe three patients with absent nasal cavity on the side of lacrimal obstruction, where DCR was performed by the creation of an anastomosis between the lacrimal sac and the contralateral nasal space.

Cerebrospinal fluid leakage after endonasal dacryocystorhinostomy.
(32/75)
An endonasal dacryocystorhinostomy (DCR) was followed by cerebrospinal fluid leakage and pneumoencephalocele in an 80-year-old female patient presenting four independent risk factors for an ethmoidal breach: severe septal deviation requiring forced reclining, a cranial insertion of the perpendicular plate of the ethmoid directly onto the cribriform plate, meningeal prolapse, and extensive osteoporosis of the skull base. The use of a Killian valve speculum to recline the nasal septum was probably the main cause of the anterior skull base fracture. The defect was repaired by a composite patch of septal cartilage, abdominal fat grafts, Surgicel, and inferior turbinate mucosa. Thirty-four months after surgery, there was no residual symptom. A narrow nasal fossa makes endoscopic DCR more difficult to perform. The use of a Killian valve speculum to enlarge the nasal fossa may carry a risk for structural damage to the skull base. A narrow nasal fossa may require an external DCR or a prior endoscopic septoplasty to facilitate an endonasal approach. Closing an ethmoidal defect causing cerebrospinal fluid leakage can be successfully achieved by an endonasal approach rather than by a more conventional neurosurgical method. (+info)
