Conjunctival Sparing Ptosis Correction by White-Line Advancement Technique.

ABSTRACT: Purpose:To describe a modified technique of white line advancement posterior ptosis surgery and to report the success rate of the procedure. Methods:A retrospective case series of 60 patients who presented with ptosis with good levator function. The success rate was defined as an MRD1 of greater than or equal to 3.5?mm, symmetrical eyelid position with an intereyelid height asymmetry of ?1?mm, and a satisfactory eyelid contour at 3 months follow-up. Results:Sixty patients (91 eyelids) met the inclusion criteria. Mild postoperative complications occurred in 11 patients that resolved without surgical intervention. Seven patients had recurrence of ptosis: four patients had early recurrence and 3 had late recurrence. The success rate was 88.33% with an average follow-up of 9 months. Conclusion:This procedure is a promising technique in cosmetic and functional ptosis correction. The advantage of this posterior approach procedure is that there is no conjunctival resection; it is suitable for young patients who do not have excess eyelid skin. The procedure is quick with a short recovery period. Additionally, it can be combined with another procedure and in different pathology.

Project description:BackgroundMargin Reflex Distance 1(MRD 1) only describes the central height of upper eyelid and relies on the examiner's experience and disregards eyelid contour abnormalities. Therefore MRD 1 may not be sufficient for an acceptable result to evaluate the outcomes of ptosis surgery. The primary purpose of this study was to assess outcomes of unilateral ptosis correction based on parameters including degree of symmetry, MRD 1, peak height of the upper lid, temporal and nasal ocular surface area, and temporal/nasal area ratio with an objective, quantitative, and repeatable method.MethodsThis study was designed as a retrospective non-randomized case-control study. Medical records of the patients with unilateral ptosis between October 2015 and December 2020 were reviewed. Patients with unilateral ptosis who underwent surgical correction and levator function of 5 mm or greater were included in the study. Two groups were defined; ptotic eye was case group and contralateral eye was control group. Data analysis was performed Image J and Matlab softwares.ResultsThirty-four patients were included in the study. Mean age of patients was 58.8 ± 12.7 years (range 15-75 years). Mean follow-up time was 19.5 ± 7.3 months (range 8-40 months). Four patients were diagnosed with congenital ptosis and 30 patients aponeurotic ptosis. Mean preoperative degree of symmetry for overall eyelid contour was 36.6 ± 27.5% (range 1-92%). Mean postoperative degree of symmetry for overall eyelid contour was 72.4 ± 16.5% (range 55-92%). Temporal/Nasal (T/N) area ratios for contralateral normal eye was 1.19 pre-postoperative, and it was 1.11 preoperatively, 1.15 postoperatively for operated ptotic eye.ConclusionsThis study primarily demonstrated a quantitative, objective, and repeatable method to investigate the degree of symmetry after eyelid surgeries. Secondly, this study suggested that T/N ratio may not be a reliable parameter to evaluate the eyelid symmetry.

Project description:BackgroundPreviously, the authors modified the surgical technique to preserve tibial bone mass for Oxford unicompartmental knee arthroplasty (UKA). The purpose of this study was to determine the clinical outcomes and values of this modified technique.MethodsClinical data of 34 consecutive patients who underwent the unilateral modified UKA technique (modified group, 34 knees) were retrospectively analyzed. To compare the outcome, a match-paired control group (conventional group, 34 knees) of an equal number of patients using the conventional technique system in the same period were selected and matched with respect to diagnosis, age, pre-operative range of motion (ROM), and radiological grade of knee arthrosis. Clinical outcomes including knee Hospital for Special Surgery (HSS) score, ROM, and complications were compared between the two groups. Post-operative radiographic assessments included hip-knee-ankle angle (HKA), joint line change, implant position, and alignment.ResultsThe mean follow-up time was 38.2 ± 6.3 months. There was no difference in baseline between the two groups. The amount of proximal tibial bone cut in the modified group was significantly less than that of the conventional group (4.7 ± 1.1 mm vs. 6.7 ± 1.3 mm, t = 6.45, P < 0.001). Joint line was elevated by 2.1 ± 1.0 mm in the modified group compared with -0.5 ± 1.7 mm in the conventional group (t = -7.46, P < 0.001). No significant differences were observed between the two groups after UKA with respect to HSS score, VAS score, ROM, and HKA. Additionally, the accuracy of the post-operative implant position and alignment was similar in both groups. As for implant size, the tibial implant size in the modified group was larger than that in the conventional group (χ = 4.95, P = 0.035).ConclusionsThe modified technique for tibial bone sparing was comparable with the conventional technique in terms of clinical outcomes and radiographic assessments. It can preserve tibial bone mass and achieve a larger cement surface on the tibial side.
