Upper Eyelid Contour Changes After Müller's Muscle Conjunctiva Resection.

PURPOSE: To analyze the upper eyelid contour after Müller's muscle conjunctiva resection (MMCR) performed by four different surgeons. METHODS: Comparative cross-sectional analysis of the pre- and postoperative contours of a control group and four groups of upper lids (n = 88) of 65 patients who underwent MMCR at four international centers. The procedure employed was essentially the same as described by Putterman but performed with different instruments to entrap the posterior lamella. Multiple medial and lateral margin lid distances were measured on Bézier lines expressing the pre- and postoperative lid contours. RESULTS: Preoperatively, two groups had significant lateral and medial ptosis. After MMCR, the lateral segment of the lid's contour was corrected in all groups. In the two groups with more pronounced ptosis, the nasal lid contour was undercorrected. CONCLUSIONS: In MMCR, regardless of the instrument used to entrap the posterior lamella, the amount of medial tissue resection is essential to avoid postoperative nasal undercorrection.

Outcomes of Orbital Blow-Out Fracture Repair Performed Beyond 6 Weeks After Injury.

PURPOSE: Blow-out fractures cause expansion of the bony orbital walls and prolapse of orbital contents in the sinuses. This can result in diplopia, enophthalmos, and hypoglobus. Early surgical repair has been previously recommended, however, recent reports show that delayed surgery can also be effective. In this study, the clinical and functional outcome of patients with delayed presentation and blow-out fracture repair beyond 6 weeks after injury are described. METHODS: This is a noncomparative retrospective study. Medical records of adult patients with late orbital floor fracture repair performed by 4 surgeons from April 2008 to January 2014 at 3 tertiary referral centers were reviewed. All repairs were performed more than 6 weeks from the time of injury. Patients with prior orbital fracture repair surgery were excluded. RESULTS: Twenty patients were included in the study. The duration from time of injury to surgery ranged from 7 weeks to 21 years with a mean of 19 months. Follow up ranged from 6 weeks to 56 months (mean 8 months). Mean age was 48 years (range, 25-80). Male to female ratio was 11:9. Surgery was performed on 10 right eyes and 10 left eyes. CT imaging demonstrated 10 patients had isolated floor fractures, while the remaining 10 patients had combined floor and medial wall fractures. Four patients also had associated facial fractures that did not require surgery. Indications for surgery included enophthalmos of 2 mm or more (18 of 20) and/or significant diplopia within 30° of primary gaze (6 of 20). Mean pre- and postoperative enophthalmos was 2.4 ± 0.9 mm and 0.3 ± 0.2 mm, respectively, corresponding to a mean reduction in enophthalmos of 2.1 ± 1.2 mm (range, 1-5 mm). Four of 7 patients with hypoglobus ranging from 1.5 mm to 8 mm preoperatively had complete resolution postoperatively, the remaining 3 patients showed reduced hypoglobus. Of the 12 patients that had diplopia preoperatively in any position of gaze, 6 patients had complete resolution of diplopia postoperatively, 4 patients had reduced but residual diplopia in extreme gaze, and 2 patients had persistent diplopia, in primary position and down gaze, respectively. Two patients had poor vision that precluded the manifestation of diplopia. None of the 6 patients without preoperative diplopia developed symptoms post operatively. CONCLUSION: Surgical repair of blow-out fractures of the orbit occurring more than 6 weeks or more from injury can achieve marked improvement in both the functional and cosmetic aspects. The likelihood of induced diplopia is low. Orbital floor fracture repair should be considered to successfully treat enophthalmos or diplopia in patients with delayed clinical presentation, even decades postinjury.

Silicone intubation for the treatment of epiphora in adults with presumed functional nasolacrimal duct obstruction.

PURPOSE: To evaluate the long-term efficacy of silicone intubation in adults with presumed functional nasolacrimal duct obstruction. METHODS: This retrospective cohort study reviewed adults with unilateral or bilateral epiphora and presumed functional nasolacrimal duct obstruction treated with silicone intubation and followed for signs of treatment failure (defined as persistent epiphora or need for a secondary procedure). Median time to event (failure) after silicone intubation was calculated using Kaplan-Meier survival analysis. Analysis was conducted at the level of the individual eye, with clustering by person taken in account. Cox proportional hazards models were used and adjusted for within-subject variance using a robust sandwich estimator. RESULTS: Forty-four eyes from 30 patients with isolated functional nasolacrimal duct obstruction underwent silicone intubation for epiphora. Mean time to stent removal in 40 of 44 eyes was 4.0 (±4.1) months. Mean duration from the time of stent placement to last follow-up was 2.6 (±2.0) years. Overall success after silicone intubation for resolution of symptoms was 77%. Kaplan-Meier survival analysis for time to event after silicone intubation yielded a median time of 5.7 years. Extrapolated data demonstrated a 96% success rate at 2 years and 85% success rate at 3 years and predicted approximately 50% of patients to have relief of epiphora between 5 and 6 years after silicone intubation. CONCLUSIONS: In this study, silicone intubation has good long-term success for relief of epiphora in patients with presumed functional nasolacrimal duct obstruction. This study provides important clinical information to guide management of epiphora in adults with functional nasolacrimal duct obstruction.

Assessment of Lacrijet monocanalicular intubation for congenital nasolacrimal duct obstruction.

PURPOSE: To assess the success rate and complications of Lacrijet monocanalicular stent (FCI S.A.S, Paris, France) intubation in children treated for congenital nasolacrimal duct obstruction (CNLDO). METHODS: Retrospective review study which included children with CNLDO that were intubated with Lacrijet monocanalucilar silicone tube.The Lacrijet tube remained in place for 11-15 weeks post operatively and was removed in the clinic with topical anesthesia. Operative time was recorded for each case. All children were evaluated using the following parameters preoperatively and postoperatively: tear meniscus height, Fluorescein dye disappearance test (FDDT), and MUNK score. RESULTS: The study included 20 eyes with mean age of 26.25 ± 11.25 months. 17 eyes (85%) had undergone probing previously. Mean operation time of Lacrijet intubation was 8.5 min (95% CI 7.04-9.95). Mean follow-up period was 204.65 ± 105.27 days. Lacrijet intubation resulted in statistically significant improvements in tear meniscus height (P < .001), FDDT (P < 0.001), and MUNK score (P < 0.001) in all children. Two different sizes of Lacrijet intubations were used. Complete success was obtained in all cases. No complications were observed. CONCLUSIONS: Lacrijet lacrimal intubation has a high rate of success, shortens surgical time and has a low rate of complications in children with CNLDO.

Nonlaser endoscopic endonasal dacryocystorhinostomy with adjunctive mitomycin C in nasolacrimal duct obstruction in adults.

PURPOSE: To determine the outcome and safety of nonlaser endonasal dacryocystorhinostomy (NLEN-DCR) with the use of adjunctive mitomycin C (MMC) in congenital, traumatic, and primary acquired nasolacrimal duct obstruction in adults. DESIGN: Retrospective, nonrandomized, noncomparative, case series. PARTICIPANTS: One hundred ninety-three consecutive adult patients underwent NLEN-DCR with the use of adjunctive MMC. Thirty-one patients had a simultaneous bilateral procedure performed. METHODS: All patients underwent a standardized procedure, with an endonasal approach to the lacrimal sac, surgical removal of nasal mucosa, lacrimal bone, and a fragment of the frontal process of the maxilla. The medial wall of the lacrimal sac was removed completely, and a neurosurgical cottonoid soaked in MMC at 0.5 mg/ml was placed at the osteotomy site for 10 minutes. All patients underwent bicanalicular silicone intubation. MAIN OUTCOME MEASURES: Resolution of epiphora, absence of discharge, and patency of the ostium confirmed by irrigation at 6 months. RESULTS: The NLEN-DCR procedure with adjunctive MMC was successful in 212 (95%) cases. The mean follow-up was 18.2 months. Intubation of more than 3 months was associated with a higher rate of obstruction (P<0.00018, Fisher exact test), with 9 eyes of 8 patients losing patency. Age, diagnosis, side operated, or infection at the time of surgery had no influence on the final outcome. No significant complications were encountered. CONCLUSIONS: Results suggest that NLEN-DCR with MMC is a safe and successful procedure for the treatment of congenital, traumatic, and primary acquired nasolacrimal duct obstruction in adults. It has the advantage of leaving no scar and of preserving the medial canthal structures. It can be performed successfully as a simultaneous bilateral procedure.

Topical mitomycin in endoscopic-assisted probing for the treatment of congenital nasolacrimal duct obstruction in older children.

PURPOSE: Mitomycin C has been used in ophthalmic surgery to mitigate postoperative scarring. However, the outcomes of endoscopic-assisted probing for the treatment of congenital nasolacrimal duct obstruction with adjunctive mitomycin C in children remain unknown. Our study was aimed to evaluate the efficacy and safety of adjunctive application of mitomycin C after endoscopic-assisted probing for the treatment of congenital nasolacrimal duct obstruction in children. METHODS: This is a retrospective chart review performed in a tertiary eye care hospital involving children with congenital nasolacrimal duct obstruction, who underwent endoscopic-assisted probing from October 2013 to August 2015. We compared children who underwent endoscopic-assisted probing with mitomycin C (mitomycin C group) versus others who underwent endoscopic-assisted probing without mitomycin C (endoscopic-assisted probing group). The mitomycin C group received 0.2 mg/ml within 4 min to the nasolacrimal duct ostium using a cotton tip applicator immediately after probing. Probing was considered successful when patient complaints of tearing were reduced or the results of the dye disappearance test were normal. Demographic data, clinical features, and intraoperative and postoperative variables were correlated to the success rate. RESULTS: The study sample comprised 68 lacrimal vies. The majority of children had bilateral obstruction and no previous history of probing. The mean age of the patients was approximately 4 years. Most obstructions were considered complex. The success rates were high in both groups (p>0.05). There were no adverse events related to the use of mitomycin C (p>0.05). CONCLUSIONS: Although mitomycin C has no adverse effects when applied to the opening of the nasolacrimal duct, its use after lacrimal probing for the treatment of congenital nasolacrimal duct obstruction does not improve the chance of success.

Nonlaser endoscopic endonasal dacryocystorhinostomy with adjunctive mitomycin C in children.

PURPOSE: To determine the outcome and safety of pediatric endonasal dacryocystorhinostomy with the use of adjunctive mitomycin C. METHODS: A prospective, nonrandomized and noncomparative interventional case series study was performed in 71 consecutive procedures. Sixty patients 16 years of age and younger underwent nonlaser endonasal dacryocystorhinostomy with the use of adjunctive mitomycin C. Eleven patients had a simultaneous bilateral procedure performed. All patients underwent a standardized procedure, with an endonasal approach to the lacrimal sac and surgical removal of nasal mucosa, lacrimal bone, and a fragment of the frontal process of the maxilla. The medial wall of the lacrimal sac was completely removed and a neurosurgical cottonoid soaked in mitomycin C at 0.5 mg/ml placed at the osteotomy site for 5 minutes. All patients underwent bicanalicular or monocanalicular silicone intubation. RESULTS: The main outcome measures were the resolution of epiphora, lacrimal discharge, and patency of the ostium confirmed either by endoscopic visualization and/or irrigation at 6 months or a normal dye disappearance test. Thirteen patients' (18%) final evaluation was via telephone survey. The mean follow-up was 12.3 months. Nonlaser endonasal dacryocystorhinostomy with adjunctive mitomycin C was successful in 67 cases (94.4%). African descent was strongly associated with a higher rate of obstruction (p < 0.001). Infection at the time of surgery (p = 0.051) and less than 3 months intubation (p = 0.059) were also borderline significant. Previous trauma, gender, age, and side operated had no influence on the final outcome. No significant complications were encountered. CONCLUSIONS: Nonlaser endonasal dacryocystorhinostomy with mitomycin C is a safe and successful procedure for the treatment of congenital nasolacrimal duct obstruction in children. It has the advantage of leaving no scar and of preserving the medial canthal structures. It can be successfully performed as a simultaneous bilateral procedure.

Success Rates of Endoscopic-Assisted Probing Compared to Conventional Probing in Children 48 Months or Older.

BACKGROUND: To evaluate the success rates of endoscopic-assisted probing compared to conventional probing in children 48 months or older. METHODS: This retrospective study included children 48 months and older with CNLDO who underwent endoscopic-assisted probing or conventional probing between January 2011 to August 2015 at a tertiary eye care hospital in central Saudi Arabia. Probing was considered successful when signals of tearing or discharge disappeared and fluorescein dye disappearance test (FDDT) was normal. Demographic data, clinical features, intraoperative and postoperative variables were correlated to the success rate. RESULTS: One hundred and twelve children with CNLDO undergoing endoscopic-assisted (37 patients) or conventional (75 patients) probing were included. The success rates of endoscopic-assisted and conventional probing were 94.6% [95% confidence interval (CI): 89.5-99.7] and 58.7% [95% (CI): 47.6-69.8], respectively. The success rate was higher with endoscopic probing, especially in older children. CONCLUSIONS: Endoscopic-assisted probing can achieve better outcomes to treat CNLDO, even in older children. The significantly higher success rates with endoscopic probing are likely due to the ability to observe and treat associated problems.

RESUMO Objetivo: A mitomicina C tem sido usada em cirurgia oftálmica para reduzir cicatrizes pós-operatórias. Entretanto, os resultados da sondagem endoscópica assistida para o tratamento da obstrução congênita do ducto nasolacrimal com mitomicina C adjuvante em crianças permanecem desconhecidos. Nosso estudo teve como objetivo avaliar a eficácia e a segurança da aplicação da mitomicina C após a sondagem endoscópica assistida para o tratamento da obstrução congênita do ducto nasolacrimal em crianças. Métodos: Trata-se de uma revisão retrospectiva de prontuários, realizads em um hospital terciário de oftalmologia, envolvendo crianças com obstrução congênita do ducto nasolacrimal, submetidas à sondagem endoscópica de Outubro de 2013 a Agosto de 2015. Comparamos crianças submetidas à sondagem endoscópica com mitomicina C (grupo mitomicina C) versus outros que foram submetidos à sondagem endoscópica sem mitomicina C (grupo de sondagem endoscópica). O grupo mitomicina C recebeu 0,2 mg/ml em 4 min para o óstio do ducto nasolacrimal usando um aplicador de ponta de algodão imediatamente após a sondagem. A sondagem foi considerada bem-sucedida quando as queixas de lacrimejamento dos pacientes foram reduzidas ou os resultados do teste de desaparecimento do corante foram normais. Dados demográficos, sinais clínicos, variáveis intra e pós-operatórias foram correlacionados com a taxa de sucesso. Resultados: A amostra do estudo foi composta por 68 vias lacrimais. A maioria das crianças apresentava obstrução bilateral e sem histórico prévio de sondagem. A média de idade dos pacientes era de aproximadamente 4 anos. A maioria das obstruções foi considerada complexa. As taxas de sucesso foram altas nos dois grupos (p>0.05). Não houve efeitos adversos relacionados ao uso da mitomicina C (p>0.05). Conclusões: Apesar a mitomicina C não tenha efeitos adversos quando aplicada à abertura do ducto nasolacrimal, seu uso após sondagem lacrimal no tratamento da obstrução congênita do ducto nasolacrimal não melhora a chance de sucesso.
