frontalis muscle transfer technique for correction of severe Congenital Blepharoptosis in chinese patients an analysis of surgical outcomes related to frontalis muscle function
Journal of Plastic Reconstructive and Aesthetic Surgery, 2015Co-Authors: Ying Shao, Bing Li, Xiaojie Yu, Duo ZhangAbstract:Summary Aim The aim of this study is to evaluate the surgical outcomes related to frontalis muscle function using the frontalis muscle transfer technique in Chinese patients with severe Congenital Blepharoptosis and poor levator function. Materials and method Between December 2003 and December 2011, using the frontalis muscle transfer technique, 37 patients of Chinese origin underwent surgery on 53 eyelids. The frontalis muscle function was assessed and categorized as poor (excursion ≤ 7 mm) and good (excursion > 7 mm) before the surgery. The results, including complications of the treatment procedure, were followed up and evaluated. Using the Cochran–Mantel–Haenszel statistic, the preoperative ptosis severity was compared with the degree of ptosis correction, and the preoperative frontalis muscle function was compared with the degree of ptosis correction using Fisher's exact test for paired data. A two-sided value of p Results Of the total eyelids considered, sufficient postoperative correction of ptosis was achieved in 43 eyelids (81.1%), while the correction was insufficient in 10 eyelids (18.9%). Fifteen (28.3%) eyelids were either overcorrected ( n = 5) or undercorrected ( n = 10). The rate of lagophthalmos was 3.8%. Eyelids with preoperative frontalis muscle function >7 mm had a higher rate of sufficient correction in comparison to those with preoperative frontalis muscle function ≤7 mm (91.2% vs. 63.2%; p Conclusion The frontalis muscle is the main motor muscle used in the correction of severe Blepharoptosis via the frontalis muscle transfer technique. Although the technique is considered to be an effective surgical method for the correction of severe Blepharoptosis, the outcome of the correction procedure depends on the preoperative frontalis muscle function of the patient.

two different correction surgery for Congenital Blepharoptosis
Journal of Hainan Medical University, 2012Co-Authors: Zhu JialiAbstract:Objective: To compare two correction surgery for Congenital Blepharoptosis.Methods:A total of 126 eyes of 98 patients with Congenital Blepharoptosis admitted from August 2001 to August 2011 were selected.They had levator palpebrae superioris muscle shortening and frontalis muscle suspension surgery and were followed up for 4 weeks.Results:Levator palpebrae superioris muscle shortening for mild Congenital Blepharoptosis patients was significantly more effective than it for moderate and severe Congenital Blepharoptosis patients(P 0.05);while frontalis muscle suspension surgery was more effective for moderate and severe Congenital Blepharoptosis patients(P 0.05).Conclusions:Levator palpebrae superioris muscle shortening can keep function of palpebra superior,and achieve cosmetic purpose,which is applicable to mild Congenital Blepharoptosis;frontalis muscle suspension surgery can shift palpebra superior,and can apply to moderate and severe Congenital Blepharoptosis.

clinical effect and safety of the technique by shortening the levator palpebrae superioris muscle and the musculus frontalis flap suspension surgery for morderate Congenital Blepharoptosis
Hainan Medical Journal, 2013Co-Authors: Zhao JianmiAbstract:Objective To investigate the clinical effect and safety of the technique by shortening the levator palpebrae superior muscle and the musculus frontalis flap suspension surgery for morderate Congenital Blepharoptosis.Methods One hundred and eight patients with morderate Congenital Blepharoptosis were analyzed and divided into two groups randomly to receive different operative treatments from May 2010 to May 2012.Fifty-six patients were selected and operated by shortening the levator palpebrae superioris musle(Group A),while 52 patients were operated with frontal muscle suspension(Group B).The clinical effect and adverse reactions were compared between the two different operation modes for morderate Congenital Blepharoptosis.Results In group A,53 patients were well corrected after surgery in Group A,and the effect rate was 94.6%,which was higher than that in Group B(71.2%),with significantly difference between the two groups(P0.05).Most patients' vision were improved to varying degress acuity,the incidence of complications in Group A and Group B were 6.25% and 23.1%,respectively,with significant difference(P0.05).Conclusion The method of shortening the levator palpebrae superior muscle can be taken as first choice for Congenital Blepharoptosis.

Outcomes of anterior levator resection in Congenital Blepharoptosis.
Eye (London England), 2020Co-Authors: C A Cates, A G TyersAbstract:To identify any consistent factors which may predict over- or undercorrection of Congenital Blepharoptosis treated by anterior levator resection. A retrospective case note review of 100 consecutive patients undergoing anterior levator resection for Congenital Blepharoptosis was performed to identify: (1) the amount of ptosis and degree of levator function present pre-operatively and (2) the surgical outcome. For unilateral ptosis, a successful result was defined as a lid level within 1 mm of the fellow lid following a single operation. Seventy-six per cent of all unilateral cases had a successful outcome at 6 weeks following surgery, falling slightly to 74% by 6 months. The most common complications at 6 months were undercorrection (19%) and overcorrection (7%). All patients undercorrected at 6 months had a pre-operative levator function in the range of 4-10 mm with a mean of 6.4 mm, whereas all those overcorrected at 6 months had a levator function in the range 9-15 mm with a mean of 12.2 mm. In the whole population, the degree of levator function was a predictor of increased risk of overcorrection, with a trend towards predicting undercorrection as well. In this series of patients, pre-operative levator function was found to be the most significant predictor of surgical outcome for anterior levator resection.

eyelid retraction in isolated unilateral Congenital Blepharoptosis
Frontiers in Neurology, 2017Co-Authors: Michael S Salman, Ian ClarkAbstract:Isolated unilateral Congenital ptosis is encountered relatively infrequently in clinical practice. It typically consists of a unilateral droopy eyelid, weak levator palpebrae superioris muscle function, lid lag, and an absent upper lid crease with no other abnormalities on examination. We present a four-and-a-half year old girl with isolated and mild unilateral Congenital ptosis who unexpectedly demonstrated a static upper eyelid on downgaze in conjunction with a well-formed upper lid skin crease. We attribute this uncommon sign in Congenital ptosis to stiffness and presumed fibrosis of the levator muscle. Examining the function of the eyelids in all directions of gaze is important in patients with abnormalities of lid position, since additional useful information can be gleaned about the status of the levator muscle including, aberrant regeneration or fibrosis.
