Cause and Management of Patients With Failed Endonasal Dacryocystorhinostomy

Objectives Endonasal dacryocystorhinostomy (DCR) is a well-established treatment method in patients with nasolacrimal duct obstruction. However, there are a few reports about the overall management of failed endonasal DCR. We investigated the causes and management strategies of failed endonasal DCR. Methods This retrospective review included 61 patients (61 eyes) who had undergone revision surgery by the same surgeon after failed endonasal DCR between January 2008 and December 2012. The appropriate revision method was determined after analysis of the etiology of failure by the fluorescein dye disappearance test, nasal endoscopy, lacrimal irrigation, and probing. The criteria for success of the revision surgery were defined by the passage of fluid without resistance upon lacrimal irrigation and normalization of the tear meniscus height. Results The mean duration between the primary endonasal DCR and revision surgery was 15.3 months. The average follow-up period after revision surgery was 12.2 months. The most common cause of endoscopic revision surgery was membranous obstruction. Endoscopic revision surgery was performed in 48 patients, while lacrimal silicone tube intubation under endoscopy was performed in 13 patients. The most common indication for lacrimal silicone tube intubation was functional epiphora. The overall success rate of the revision surgery was 89%. Conclusion The most common cause of failed endonasal DCR was membranous obstruction. When patients with failed endonasal DCR presented at the clinic, it is important to identify the cause of the failure. Revision surgery could increase the final success rate of endonasal DCR.

Comparison Between Continuous Buried Suture and Interrupted Buried Suture Methods for Double Eyelid Blepharoplasty.

Purpose:The objective of this study was to compare the surgical outcomes between interrupted and continuous buried suture methods in double eyelid blepharoplasty in Koreans. Methods:Medical records of 204 patients (392 eyes) who underwent double eyelid operation by buried suture method and who were followed up for at least more than 3 months were reviewed. Patients were divided into 2 groups according to the buried suture method; an interrupted group (88 patients) and a continuous group (116 patients). Results:The rate of loss of formed double eyelid is 19.3 % (17 of 88 patients) in interrupted buried method and 8.6 % (10 of 116 patients) in continuous group (P = 0.026). One patient experienced an exposure of suture knot in a continuous group, whereas 5 patients experienced an exposure of suture knot and 1 patient suffered from granuloma in an interrupted group (P = 0.021). Conclusions:The continuous buried suture method has a lower rate of the loss of double folds and less complication than the interrupted buried suture method for double fold formation in Koreans.

Comparison of Surgical Outcome Between Quickert Suture and Quickert Suture With Modified Lateral Tarsal Strip in Involutional Lower Eyelid Entropion

Purpose:To evaluate the surgical outcome between Quickert suture and Quickert suture with modified lateral tarsal strip in involutional lower eyelid entropion. Methods:A retrospective study was performed on 76 patients (94 eyes) who had undergone Quickert suture (Group 1) and on 38 patients (44 eyes) who had undergone Quickert suture with modified lateral tarsal strip (Group 2) for correction of involutional lower eyelid entropion from January 2011 to December 2013. Results:In Group 1, recurrence rate is 25.5% (24 eyes) and mean duration to recurrence is 11.9 months in Group 1. For correction of recurrence, Quickert suture is performed in 50% (12 eyes), Quickert suture with lateral tarsal strip is performed in 37.5% (9 eyes), and lateral tarsal strip is performed in 12.5% (3 eyes). In Group 2, recurrence rate is 9.1% (4 eyes). For correction of recurrence, lower eyelid retractor reinsertion is performed in 50% (2 eyes), Quickert suture with lateral tarsal strip is performed in 25% (1 eye), and Quickert suture is performed in 25% (1 eye). Conclusions:Recurrence rate is lower in patients who had undergone Quickert suture with modified lateral tarsal strip than in a patient who had undergone Quickert suture for correction of involutional lower eyelid entropion.

Causes and Surgical Outcomes of Lower Eyelid Retraction

Purpose To investigate the causes of lower eyelid retraction and evaluate the outcomes of various surgical procedures. Methods We conducted a retrospective medical record review of patients who underwent lower eyelid retraction surgery performed by a single surgeon at Kims Eye Hospital between 2006 and 2013. We investigated the causes of lower eyelid retraction, clinical history, characteristics, treatment, and surgical outcomes. Preoperative and postoperative margin reflex distance 2 and inferior scleral show were measured for each eyelid. Success was defined as a positive eyelid elevation and a decrease in inferior scleral show. Results A total of 19 lower eyelids were treated in 14 patients with lower eyelid retraction. For cosmetic reasons, surgical correction for congenital lower eyelid retraction was performed on seven eyelids (36.8%). Ten eyelids (52.6%) exhibited secondary lower eyelid retraction after surgery. One eyelid (5.3%) was affected by facial palsy and one eyelid (5.3%) exhibited exophthalmos of an unknown origin. We adopted a selective approach based on lower eyelid retraction severity. Spacer grafting via a subconjunctival approach was the most commonly performed surgical technique (13 eyelids, 68.4%). The lateral tarsal strip procedure was used to horizontally tighten three eyelids (15.8%). At the time of the procedure, one of these eyelids (5.3%) also received an adjuvant suborbicularis oculi fat lift. Autogenous dermis fat grafting was performed on two lower eyelids (10.5%), whose retraction was caused by fat and soft tissue loss. Cosmetic outcomes were satisfactory in all cases. Conclusions To achieve satisfactory surgical outcomes, surgeons should adopt an approach based on the severity of lower eyelid retraction. Mild lower eyelid retraction can be corrected without grafts. When retraction is severe and exceeds 2 mm, spacer grafts that push the lower eyelid margin upwards and support it from below are required.

Predictors of Silicone Tube Intubation Success in Patients with Lacrimal Drainage System Stenosis

Purpose To evaluate prognostic factors affecting silicone tube intubation outcomes in Asian patients with lacrimal drainage system stenosis. Methods A retrospective review was conducted on the medical records of 822 patients (1,118 eyes) who had undergone silicone tube intubation to treat lacrimal drainage system stenosis between January 2011 and December 2012. Patients were divided into two groups: a success group and a failure group. Success was defined as the disappearance of epiphora symptoms, normalization of tear meniscus height, and the easy passage of fluid without resistance on the postoperative syringing test. Patient and ocular parameters were compared between the success and failure groups. Results A total of 994 eyes of 727 patients were included in analyses. Patients had a mean follow-up period of 34.11 ± 18.70 weeks. Silicone tube intubation was successful in 67.2% of participants. Significant differences between the success and failure groups were found for age (p < 0.001), history of ipsilateral facial palsy (p = 0.028), follow-up period (p < 0.001), and degree of passage on the preoperative syringing test (p = 0.001). Only age (p < 0.001) and degree of passage on the preoperative syringing test (p = 0.002) remained significantly associated with silicone tube intubation success in multivariate analysis. Conclusions Age was negatively associated with silicone tube intubation success in patients with lacrimal drainage system stenosis. The success rate was higher in patients who showed easy passage of fluid without resistance on the preoperative syringing test. These factors should be considered by surgeons planning silicone tube intubation in patients with lacrimal drainage system stenosis.

Clinical Features of Benign Essential Blepharospasm in Korean Patients

Purpose To analyze the clinical features of benign essential blepharospasm in Korean patients. Methods Patients diagnosed with benign essential blepharospasm in Kims Eye Hospital from November 2014 to December 2016 were evaluated using a clinical examination and questionnaire. The questionnaire reviewed personal medical history, demographic factors, risk factors for blepharospasm development, and relieving and aggravating factors. Results Of the 101 patients enrolled, 78 (77.2%) were women. The mean age was 64.9 years old. Hypertension was the most common medical disorder (42.6%), followed by diabetes mellitus. The majority of the patients were non-smokers (83.2%) and drank less than a cup of a caffeinated beverage a day (30.7%). Fifty-seven percent of patients reported no stressful events immediately prior to symptom development. Fatigue and stress were aggravating factors in more than 55% of patients; rest was the most common relieving factor (35.6%). Conclusions Here, we report the clinical features of benign essential blepharospasm in Korean patients for the first time. The results were consistent with previous reports showing that the majority of benign essential blepharospasm patients are women and non-smokers. In contrast to previous reports though, fatigue and stress were aggravating factors, and the most common relieving factor was rest. No stressful events had immediately preceded the development of blepharospasm in 57.4% of patients. This report may aid in treating and counseling patients with benign essential blepharospasm.
