Relationship between eyebrow and eye aesthetics after correction of aponeurotic ptosis / 中华医学美学美容杂志

Objective:To evaluate the specific changes and importance of the proportions of the eyebrows and eyes after surgery by analyzing and measuring the changes of the values of the eyebrows and eyes in elderly patients with aponeurotic ptosis before.Methods:A total of 54 cases (108 eyes) of elderly patients with aponeurotic ptosis who were treated in our department from 2019.01 to 2020.12 were collected preoperatively and 6 months postoperatively, and they were set as the study group. At the same time, the data of 48 cases (96 eyes) of healthy people with good face were collected and set as the young control group, and the data of 50 cases (100 eyes) of elderly healthy people without ptosis were collected and set as the elderly control group. The corresponding objective data were analyzed, and the specific changes and proportional relationship of eyebrows and eyes after surgery were evaluated.Results:Compared with the preoperative data, the marginal reflex distance 1 (MRD1), the height of the palpebral fissure (HPF) in the study group increased at 6 months after the operation, and the distance between the eyebrow and eye at each site increased or shortened ( P<0.05). Six months after the operation, the brow height from medial canthus (MBH), the central brow and eye distance (brow height from upper eyelid margin on midpupillary level, CBH), and the lateral brow and eye distance (brow height from lateral, LBH) had been changed. The change rates of canthus compared with preoperatively were that (88.29±11.69)%, (85.04±14.96)%, and (93.61±13.56)%, respectively, among which CBH shortened most significantly, and the shortened distance was (3.76±2.43) mm. The MRD1 and HPF in the group increased significantly at 6 months after operation, which were significantly greater than those in the elderly control group ( P<0.05). CBH was significantly shortened ( P<0.05); compared with preoperative, the ratio of HPF/CBH, HPF/length of the palpebral fissure (LPF) in the study group increased at 6 months after operation, and the lateral canthus brow tail line [ratio of lateral canthus to lateral end of eyebrow (LLE)]/LPF decreased ( P<0.05); HPF/CBH in the study group was lower than that in the young control group at 6 months after operation, but greater than that in the elderly control group ( P<0.05). Monthly HPF/LPF was significantly higher than that of the elderly control group ( P<0.05), and the LLE/LPF of the study group was significantly higher than that of the young control group at 6 months after operation ( P<0.05); intraoperative levator muscle shortening (LMS) was negatively correlated with postoperative MBH, CBH and LBH ( P<0.05), among which LMS had the greatest correlation with CBH ( r=-0.587). Conclusions:After ptosis correction, the palpebral fissures are larger, the distance between the eyebrows and the eyes is shortened, and there is a certain proportional relationship. After surgery, the patient's eyebrow-eye ratio is better than that of the elderly in the same age group, and it is closer to the young people, and the intraoperative LMS has a correlation with the eyebrow-eye distance, which can be used as a factor to predict the shortened distance of the eyebrow-eye distance.

Efficacy of modified Park method in blepharoplasty / 中华医学美学美容杂志

Objective:To investigate the modified application of orbicularis oculi muscle-levator aponeurosis composite tissue flap fixation technique (modified Park method) in double-eyelid surgery.Methods:From June 2019 to March 2021, 823 patients included 92 males and 731 females, aged from 18 to 45 years with mean (31.4±7.9) years, in which 142 patients with slightly ptosis were selected to receive the treatment in the Department of Plastic Surgery of the Affiliated Hospital of Nangjing University of TCM. The symmetry of bilateral double eyelids after operation was evaluated by the third party. The marginal reflex distance (MRD1) was measured before and 6 months after operation, and the difference between preoperative and postoperative MRD1 (ΔMRD1) was calculated. And the postoperative complications were counted. The patients were followed up from 6 to 12 months after surgery to evaluate the long-term results.Results:The patients were followed up for 4-22 months (mean 10 months) after operation. And the incisions of all the 823 cases had primary healling. Most patients had smooth upper eyelid crease, upturned lashes and dynamic fold. The skin tended to spread evenly without dimple. The symmetry evaluation by the third party showed that there were 764 patients with symmetry and basic symmetry after operation, the symmetry rate was 92.8%; 59 patients with asymmetry, the asymmetry rate was 7.2%. The data of MRD1 increased significantly 6 months after operation, from (3.25±0.72) mm to (3.64±0.61) mm, and the ΔMRD1 was (0.38±0.76) mm ( t=-20.41, P<0.05). The difference between the two groups was statistically significant. The double eyelid line became shallow in 8 cases and disappeared completely in 3 cases. The double eyelid curve of the patients was natural and smooth after the operation. And there was no obvious sunken scar and pretarsal fullness. Conclusions:The " modified Park technique" blepharoplasty can obtain a more firm, symmetrical and natural appearance. And the mild ptosis could be corrected by this method. The anatomical structure can be identified clearly, and the surgical results are highly repeatable. It is worth promoting.

Análisis del lexema neur(o) y sus derivados en el aprendizaje de la anatomía / Analysis of neur(o) lexeme and its derivatives in anatomy learning

La neuroanatomía es una de las ramas más complejas de abordar por los estudiantes por su lenguaje complejo y extenso. Es por ello que el término neuro podría favorecer su aprendizaje, debido a que múltiples conceptos y términos lo tienen incorporado como prefijo, sufijo o interfijo. El objetivo de estudio fue analizar el lexema neur(o) y los términos anatómicos asociados con el fin de comprender su significado y mejorar su aprendizaje. Para ello, se identificaron los términos anatómicos que contienen en su composición el lexema neur(o) en Terminologia Anatomica (TA) publicada el 2011 y analizados etimológica y semánticamente. El lexema neur(o) se repite en 26 términos anatómicos provenientes del latín y griego en los capítulos sistema esquelético (A02.0.00.000 Ossa; Systema skeletale), sistema muscular (A04.0.00.000 Musculi, Systema musculare), glándulas endocrinas (A11.0.00.000 Glandulae endocrinae) y sistema nervioso (A14.0.00.000 Systema nervosum). La raíz neur(o), tiene dos orígenes semánticos: del griego νευρον, como también del latín neruu(m), cuyos significados son nervio o tendón, como en el caso de "aponeurosis" (A04.0.00.47 Aponeurosis), conformado de Apó(αTTó): 'a partir de' + neur(νευρον): 'nervio', 'tendón' + -o-sis(o¯-sis): 'proceso', refiríendose a la membrana de tejido conjuntivo que envuelve los músculos. En conclusión, los términos anatómicos en TA poseen un origen grecolatino que hace interesante el aprendizaje, proporcionando adherencia en el proceso de aprendizaje de cada término anatómico.

Neuroanatomy is one of the most complex areas addressed by students because of its complex and extensive language. That is why the term neuro could favor its learning, because multiple concepts and terms have it incorporated as a prefix, suffix or interfix. The aim of study was to analyze neur(o) lexeme and the associated anatomical terms in order to understand its meaning and improve its learning. For this, the anatomical terms that contain neur(o) lexema in Terminologia Anatomica (TA) published in 2011 and analyzed etymologically and semantically were identified in its composition. The neur(o) lexeme is repeated in 26 anatomical terms from latin and greek in the skeletal system (A02.0.00.000 Ossa; Systema skeletale), muscular system (A04.0.00.000 Musculi, Systema musculare), endocrine glands (A11.0.00.000 Glandulae endocrinae) and nervous system (A14.0.00.000 Systema nervosum) chapters. The neur(o) root has two semantic origins: from greek νευρον, as well as from latin neruu(m), whose meanings are nerve or tendon, as in the case of "aponeurosis" (A04.0.00.47 Aponeurosis), formed by Apó(αTTó): 'from' + neur(νευρον): 'nerve', 'tendon' + -o¯-sis(o¯-sis): 'process', referring to the connective tissue membrane that surrounds the muscles. In conclusion, the anatomical terms in TA have a greek and latin origin that makes learning interesting, providing adherence in the learning process of each anatomical term.

Tratamento da parede abdominal com plicatura em Crossbow / Abdominal wall treatment with plication using the crossbow technique

Introdução: A necessidade de oferecer resultados com maior definição nas abdominoplastias nos compele a evoluir tecnicamente. O objetivo deste trabalho é apresentar a técnica de plicatura em Crossbow com suas três variantes, reforçando o conceito de aproximação vertical e horizontal da aponeurose dos músculos retos e oblíquos abdominais ao mesmo tempo, promovendo dois vetores diferentes de tração, culminando em uma maior definição da parede abdominal, principalmente na região do hipogastro e fossas ilíacas. Métodos: No período entre janeiro de 2016 e fevereiro de 2018, foram realizadas 22 cirurgias exclusivamente com a técnica Crossbow em seus tipos l, ll e lll, tanto em pacientes estéticos como pós-bariátricos. Resultados: Os resultados foram favoráveis tanto do ponto de vista estético, com maior definição do hipogastro, como do ponto de vista clínico, uma vez que nenhum paciente apresentou sinais ou sintomas diferentes de técnicas convencionais. Conclusão: A técnica Crossbow é simples e reprodutível, sendo mais um agregante na armamentária para melhorar a estética abdominal. Apesar de promover o reforço da região hipogástrica, tanto para tratamento primário como secundário desta região, só o aumento da casuística poderá demonstrar as possíveis vantagens do método.

Introduction: Owing to the need to deliver results with greater definition in abdominoplasties, techniques must evolve. The objective of this study was to introduce the crossbow technique for plication along with its three variants that reinforces the concept of vertical and horizontal alignments of the aponeurosis of the rectus and oblique abdominis muscles at the same time, promotes 2 different traction vectors, and culminates in a greater definition of the abdominal wall, mainly in the hypogastrium and iliac fossa regions. Methods: From January 2016 to February 2018, 22 surgeries were performed exclusively with the types l, ll, or lll crossbow technique, both in esthetic surgery cases and post-bariatric patients. Results: The results were favorable both from the esthetic point of view, with greater definition of the hypogastrium, and from a clinical point of view, as none of the patients showed signs or symptoms different from those of the conventional techniques. Conclusion: The crossbow technique is a simple and reproducible tool in the medical armamentarium to improve abdominal esthetics. Although it promotes the strengthening of the hypogastric region, both for primary and secondary treatments of this region, only a sample size increase can demonstrate the possible advantages of the method.

Double-eyelid blepharoplasty by turning the orbital septum downward / 中华整形外科杂志

Objective@#To investigate a new approach for double-eyelid blepharoplasty.@*Methods@#Double-eyelid blepharoplasty was performed by turning the orbital septum downward and fixing it to the upper border of the lower orbicularis oculi muscle and posterior pretarsal fascia, which is imitating physiological mechanical conduction. During double-eyelid blepharoplasty, the orbital septum was cut horizontally. Using the fusion of the levator aponeurosis with septum as a pedicle, the lower part of the orbital septum was turned downward and then sutured to the upper border of the lower orbicularis oculi muscle and posterior pretarsal fascia. We evaluated the outcomes of this double-eyelid surgical procedure in patients undergoing the procedure from December 2015 to February 2018.@*Results@#622 eyes of 311 patients were included in the final analysis. Sutures were removed 7 days after surgery. All double-eyelid lines were well-formed, and the eyelids closed well. Three-to twelve-month follow-up results revealed that the double-eyelid shape was natural, no patients experienced upper eyelid retraction or incomplete eye closure. Notched scars did not occur, and patient satisfaction was achieved in all cases. 281 patients were fully satisfied with the surgical results and 30 were basically satisfied with the surgical results.@*Conclusions@#Turning the orbital septum downward is a good approach for double-eyelid blepharoplasty.

Masticatory muscle tendon-aponeurosis hyperplasia accompanied by limited mouth opening

Patients with masticatory muscle tendon-aponeurosis hyperplasia (MMTAH) experience limited mouth opening due to restricted muscle extension. Hyperplastic aponeurosis and tendons lead to the restriction of muscle extension. The criteria for the diagnosis of MMTAH are limited mouth opening that progresses very slowly from adolescence, intraoral palpation reveals a hard cord-like structure along the overhang of the anterior border of the masseter muscle on maximum mouth opening, and a square mandible. Conservative treatment, including pharmacotherapy, occlusal splint and physical therapy are ineffective. The standard therapy is surgical treatment, such as anterior partial aponeurectomy of the masseter muscle and coronoidectomy. The long-term results are very satisfying.

Resección modificada de la aponeurosis del elevador del párpado superior / Modified resection of the upper eyelid levator aponeurosis

Objetivo: Describir la utilidad de la técnica de resección modificada de la aponeurosis. Método: Se realizó un estudio observacional, descriptivo y prospectivo de serie de casos con un solo grupo de control, de 13 pacientes (17 párpados), con ptosis aponeurótica sin desinserción, de febrero a diciembre del año 2017, en el Instituto Cubano de Oftalmología "Ramón Pando Ferrer". Resultados: El 61,5 por ciento fue del sexo masculino y el 30,7 por ciento eran mayores de 60 años. El 30,7 por ciento presentaba ptosis senil y el 47,1 por ciento era severa. La función del músculo elevador resultó buena en el 64,7 por ciento y se logró la corrección quirúrgica en el 88,3 por ciento. Se presentó el 30 por ciento de complicaciones. Conclusiones: La ptosis resulta más frecuente en pacientes mayores de 60 años del sexo masculino, con predominio de la ptosis involutivo-senil, unilateral y severa. La técnica de resección modificada de la aponeurosis resulta efectiva en la mayoría de los casos, en los que se presenta un mínimo de complicaciones. En los pacientes en quienes no se logra la corrección, esto ha estado determinado por una débil inserción de la aponeurosis al tarso, dado por el sangramiento profuso que impide la correcta visualización de los planos quirúrgicos(AU)

Objective: Describe the usefulness of the technique of modified aponeurosis resection. Methods: An observational descriptive prospective case-series study was conducted with a single control group of 13 patients (17 eyelids) with aponeurotic ptosis without disinsertion, from February to December 2017 at "Ramón Pando Ferrer" Cuban Institute of Ophthalmology. Results: 61.5 percent of the study sample were male and 30.7 percent were aged over 60 years. 30.7 percent had senile ptosis, and in 47.1 percent it was severe. Levator muscle function was good in 64.7 percent of the cases, and surgical correction was achieved in 88.3 percent. Complications occurred in 30 percent. Conclusions: Ptosis is more common among male patients aged over 60 years, with a predominance of senile involutional, unilateral and severe ptosis. The technique of modified aponeurosis resection is effective in most cases, with minimum complications. In a number of patients correction is not achieved, due to a weak insertion of the aponeurosis into the tarsus, given the profuse bleeding, which hampers correct visualization of the surgical planes(AU)

Tissue microarray technology and collagen evaluation to analyze surgical trauma performed with usual blade or ultrasonic harmonic scalpels in rats

Abstract Purpose: To compare wound healing performed with cold blade (CSB) and ultrasonic harmonic scalpel (UHS) in the abdominal aponeurosis of rats. Methods: Eighty Wistar rats divided into two groups and underwent midline incision in the linea alba with cold blade and harmonic ultrasonic scalpel. Analysis were performed in subgroups of 10 animals after 3, 7, 14 and 21 days. Macroscopically was observed the presence of hematoma, infection, wound dehiscence, fistula and adherences. Microscopically were used collagen and immunohistochemical staining methods. Results: Macroscopic, complications showed no statistical difference. Immunohistochemical analysis for MMP-9 was more intense in UHS group (p<0.05). TGF β presented its lower expression in UHS group at 14 and 21 days, with no statistical difference at 3 and 7 days (p<0.05). α-AML expression appeared higher in UHS group after 14 days and remained similar in others (p<0.05). Collagen deposition had no change in type I, and increased in type III in UHS; at 7th day the deposition was higher in CSB group; at 14th was similar in both groups (p<0.001). Conclusion: UHS compared to the CSB has higher lesion area at the time of the incision; as well as it led to the delay of regeneration and scar maturation process.

The plantar aponeurosis in fetuses and adults: an aponeurosis or fascia? / La aponeurosis plantar en fetos y adultos: ¿aponeurosis o fascia?

The plantar aponeurosis (PA), which is a thickened layer of deep fascia located on the plantar surface of the foot, is comprised of three parts. There are differing opinions on its nomenclature since various authors use the terms PA and plantar fascia (PF) interchangeably. In addition, the variable classifications of its parts has led to confusion. In order to assess the nature of the PA, this study documented its morphology. Furthermore, a pilot histological analysis was conducted to examine whether the structure is an aponeurosis or fascia. This study comprised of a morphological analysis of the three parts of the PA by micro- and macro-dissection of 50 fetal and 50 adult cadaveric feet, respectively (total n=100). Furthermore, a pilot histological analysis was conducted on five fetuses (n=10) and five adults (n=10) (total n=20). In each foot, the histological analysis was conducted on the three parts of the plantar aponeurosis, i.e. the central, lateral, and medial at their calcaneal origin (total n=60). Fetuses: i) Morphology: In 66 % (33/50) of the specimens, the standard anatomical pattern was observed, viz. three parts (i.e. central, lateral, medial) that originated from the medial and lateral processes of the calcaneal tuberosity and inserted onto the metatarsals. In 18 % (9/50) of the specimens, a two-part structure was observed. Variable origins of the medial part were noted in 16 % (8/50) of the specimens. In order to document these variations, the central part of the PA was divided into three segments (i.e. upper, middle, lower): a) In 63 % (5/8) of the specimens, the medial part arose from the middle segment; b) In 37 % (3/8) of the specimens, the medial part arose from the middle and upper segments. ii) Histological analysis: a) The central part contained longitudinally arranged semi-dense type I collagen fibres with fibroblasts; b) The lateral part displayed semi-dense type I collagen fibres with fibroblasts, hyaluronic acid, corpusculum sensorium fusiforme (Ruffini corpuscle) and corpusculum lamellosum (Pacinian corpuscle); c) The medial part comprised of loose connective tissue with elastic and reticular fibres. Adults: i) Morphology: In 100 % of the specimens, the standard anatomical pattern was observed. ii) Histological Analysis: a) In the central part, longitudinally arranged type I collagen fibres with fibroblasts were visible; b) The lateral part contained longitudinally arranged type I collagen fibres with fibroblasts; c) The medial part comprised of loose connective tissue, type I and type III collagen fibres, elastic and reticular fibres. In the current study, the morphology of the PA in fetuses and adults conformed to the standard anatomical description with variations in the origin of the medial part observed in fetuses. In addition, the fetal specimens displayed a two-part structure of the PA when the medial part was absent. Microscopically, the findings suggest that only the central and lateral parts may be considered as the PA, whilst the medial part may be termed the PF.

La aponeurosis plantar (AP), que es una capa engrosada de fascia profunda localizada en la superficie plantar del pie, está compuesta de tres partes. Hay diferentes opiniones sobre su nomenclatura, ya que varios autores utilizan los términos AP y fascia plantar (FP) de forma intercambiable. Además, las distintas clasificaciones de sus partes han dado lugar a confusión. Con el fin de evaluar la naturaleza de la AP, este estudio documentó su morfología. Además, se realizó un análisis histológico para examinar si la estructura es una aponeurosis o fascia. Este estudio consistió en un análisis morfológico de las tres partes de la AP de 50 pies de fetos y 50 pies de cadáveres adultos, por micro y macrodisección, respectivamente (total n = 100). Además, se realizó un análisis histológico en cinco fetos (n = 10) y cinco adultos (n = 10) (total n = 20). En cada pie, el análisis histológico se realizó sobre las tres partes de la aponeurosis plantar, es decir, la central, lateral y medial en su origen calcáneo (total n = 60). Fetos: i) Morfología: En el 66 % (33/50) de los especímenes, se observó el patrón anatómico estándar, es decir, tres partes (central, lateral y medial) que se originaron a partir de los procesos medial y lateral de la tuberosidad calcánea y se insertaban en los metatarsianos. En 18 % (9/50) de los especímenes, se observó una estructura de dos partes. Los orígenes variables de la parte mediana se visualizaron en el 16 % (8/50) de los especímenes. Para documentar estas variaciones, la parte central de la AP se dividió en tres segmentos (superior, medio, inferior): en el 63 % (5/8) de los casos, la parte mediana surgió del segmento medio; en el 37 % (3/8) de los casos, los casos la parte medial surgió de los segmentos medio y superior. ii) Análisis histológico: a) La parte central contenía fibras de colágeno tipo I semi-densas dispuestas longitudinalmente con fibroblastos; b) La parte lateral mostró fibras de colágeno tipo I semi-densas con fibroblastos, ácido hialurónico, corpúsculo sensorial fusiform (corpúsculo de Ruffini) y corpúsculo lamellosum (corpúsculo de Pacini); c) La parte medial comprende tejido conjuntivo suelto con fibras elásticas y reticulares. Adultos: i) Morfología: En el 100 % de los especímenes se observó el patrón anatómico estándar. ii) Análisis histológico: a) En la parte central, se observaron fibras de colágeno de tipo I con disposición longitudinal de fibroblastos; b) La parte lateral contenía fibras de colágeno de tipo I dispuestas longitudinalmente con fibroblastos; c) La parte medial estaba compuesta de tejido conectivo suelto, fibras de colágenos tipo I y tipo III, fibras elásticas y reticulares. En el presente estudio, la morfología de la AP en fetos y adultos se ajustó a la descripción anatómica estándar con variaciones en el origen de la parte medial observada en fetos. Además, los especímenes fetales mostraron una estructura de dos partes de la AP cuando la parte medial estaba ausente. Microscópicamente, los hallazgos sugieren que sólo las partes central y lateral pueden considerarse como AP, mientras que la parte medial puede denominarse FP.

Clinical application of orbicularis oculi-levator aponeurosis fixation technique (Park) in double-eyelid operation / 中华医学美学美容杂志

Objective To investigate the application of orbicularis oculi-levator aponeurosis fixation technique (Park) in double-eyelid operation.Methods From June 2014 to March 2016,136 male and 1248 female patients (436 patients with ptosis) were selected to receive the treatment.Results The incision healed well without obvious postoperative hematoma.The patients were followed up to 4-22 months (mean 10m) after operation.Most patients had smooth upper eyelid crease,upturned lashes and dynamic fold.The skin tended to spread evenly without dimple.The ptosis were also corrected.Still,there were 16 patients with the crease disappeared,11 patients with asymmetry crease,10patients showing an incomplete line,and 9 patients with the accordion effect.Conclusions The orbicularis oculi-levator aponeurosis fixation technique is a minimally-invasive procedure and decreases the recovery time.It is more solid compared with suturing technique,and can avoid sunken,depression,puffiness compared with a traditional full-cutting method.It looks more like a natural double eyelid because of protecting the orbicularis oculi muscle.

The Effectiveness of Plantar Aponeurosis Release for the Limitation in First Metatarsophalangeal Joint Extension after Hallux Valgus Surgery / 대한족부족관절학회지

PURPOSE: Stiffness in the first metatarsophalangeal joint after surgery for hallux valgus has been reported. The goal of this study was to test the efficacy of releasing plantar aponeurosis for improving the range of extension in the first metatarsophalangeal joint that was limited after hallux valgus surgery. MATERIALS AND METHODS: Thirteen patients (1 man, 12 women [17 feet]; median age, 54.4 years; range, 44~69 years) with limited first metatarsophalangeal joint extension after hallux valgus surgery, who underwent an additional procedure of plantar aponeurosis release between March 2015 and August 2015, were included. Subsequently, the passive range of extension in the first metatarsophalangeal joint was evaluated via knee extension and flexion positions. Hallux valgus angle, inter-metatarsal angle, distal metatarsal articular angle, and talo-first metatarsal angle were measured on weightbearing dorsoplantar and lateral radiographs of the foot preoperatively. RESULTS: The mean range of extension for the first metatarsophalangeal joint improved significantly, from 2.5° to 40.9° in the knee extension position (p<0.00). The mean extension range for the first metatarsophalangeal joint also improved, from 18.2° to 43.2° in the knee flexion position (p<0.00). In all patients, congruence of the first metatarsophalangeal joint was recovered. CONCLUSION: Plantar aponeurosis release is an effective additional procedure for improving the extension range of the first metatarsophalangeal joint after hallux valgus surgery.

Eyelid Contour Analysis Following Müller's Muscle-conjunctival Resection and Levator Aponeurosis Advancement in Mild to Moderate Belpharoptosis

PURPOSE: To analyze both the effects and the eyelid contour of Müller's muscle-conjunctival resection and levator aponeurosis advancement in patients with mild to moderate belpharoptosis. METHODS: We conducted a retrospective cross-sectional study including 20 eyes of 16 patients who underwent Müller's muscle-conjunctival resection and 25 eyes of 17 patients who underwent levator aponeurosis advancement from January 2012 to December 2015, where each patient was followed up for at least 6 months. Surgical success was defined as either a marginal reflex distance 1 (MRD₁) elevation greater than 2.5 mm postoperatively or a bilateral MRD₁ difference less than 0.5 mm. Both the conventional and 12 oblique mid-pupil lid distances were measured every 15 degrees using custom software developed in the MATLAB program (MathWorks, Natick, MA, USA). RESULTS: The average correction of Müller's muscle-conjunctival resection was 1.1 mm, while that of levator aponeurosis advancement was 0.9 mm. There was no significant difference in MRD₁, MRD₂, function of levator palpebrae muscle, or lid contour in the preoperative status between the Müller's muscle-conjunctival resection group and the levator aponeurosis advancement group. The surgical success rate was 85% in the Müller's muscle-conjunctival resection group and 84% in the levator aponeurosis advancement group, but this difference was not significant. The postoperative lid contour (superomedial side, 15°) was more effective in the Müller's muscle-conjunctival resection group (p < 0.05). CONCLUSIONS: Overall, both types of blepharoptosis surgery were effective at correcting mild to moderate blepharoptosis. The correction of mild to moderate blepharoptosis using Müller's muscle-conjunctival resection is an effective technique for elevating the eyelid and normalizing the eyelid contour.

Comparison of efficacy of different surgeries for congenital severe ptosis / 国际眼科杂志(Guoji Yanke Zazhi)

Abstract?AIM: To comparatively analyze the efficacy and clinical value of cutting frontal muscular slap or not during frontalis aponeurosis flap suspension in treating congenital severe ptosis.?METHODS: Clinical data of 44 children ( 54 eyes ) with congenital severe ptosis treated in our hospital from May 2013 to October 2015 was retrospectively analyzed. Children included were divided into two groups according to the different ways of operation, observation group ( cutting frontal muscular slap ) and control group ( without cutting frontal muscular slap ) , 22 cases ( 27 eyes ) in each group. The general information, postoperative follow-up, eyelid closure and complication occurrence in two groups were compared.?RESULTS: The general information of the two groups had no statistical difference (P>0.05).After 1, 6mo, the cosmetic correction rate, the rate of overcorrection, and the rate of under correction in two groups had no statistical difference (P>0.05), but the activity of upper eyelid in observation group was bigger than that in control group (P0.05 ) , but eyelid fissure height in natural closed eyelids in control group was higher than that in observe group ( P<0.05 ).After 1mo, 2 eyes in control group were with abnormal feelings in frontal part, and 3 eyes in observation group.After 6mo, 2 eyes in control group were with abnormal feelings in frontal part, and 3 eyes in observation group.There were no complications such as exposure keratitis, eyelid margin deformity, infection, hematoma, and diplopia in two groups.?CONCLUSION: The total therapeutic effects of two different surgery procedures in treating severe congenital ptosis are quite similar.The surgery with cutting frontal muscular slap could improve the activity of upper eyelid and postoperative eyelid closure.

Thickness and histopathology of levator palpebrae superioris muscle in patients with simplex congenital blepharoptosis / 中华实验眼科杂志

Background The simplex congenital blepharoptosis is the common blepharon motor dysfunction disease.Some researches have shown that congenital blepharoptosis is related to the hypoplasia of levator.Objective This study was to investigate the thickness and pathological features of levator palpebrae superioris aponeurosis in congenital blepharoptosis patients.Methods A prospective cohort study was carried out in Anyang Eye Hospital from March 2012 to April 2014.Eighty-five eyes of 56 patients with congenital blepharoptosis were divided into mild (15 eyes), moderate (25 eyes) and severe blepharoptosis (19 eyes) groups, and the fellow eyes of monocular blepharoptosis was used as fellow eye group (26 eyes).Twenty-six eyes of 13 normal subjects were recruited for the normal control group.The thickness of levator aponeurosis was measured by ultrasound biomicroscope (UBM) , and the shifting range of levator aponeurosis was detected by using measuring scale.Levator aponeurosis specimens were collected during the levator palpebrae superioris shortening surgery for the pathological examination.The study was approved by the medical ethics committee of Anyang Eye Hospital, and the patients or their guardian signed the informed consent.Results The thickness of levator aponeurosis was (0.331±0.018), (0.373±0.026), (0.539± 0.023) , (0.557 ± 0.024) and (0.547 ± 0.028) mm in the severe blepharoptosis group, moderate blepharoptosis group,mild blepharoptosis group, normal control group and fellow eye group, respectively, showing a significant difference among them (F =1.681, P =0.043).The thickness values of levator aponeurosis were considerably lower in the severe blepharoptosis group and moderate blepharoptosis group than those in the mild blepharoptosis group,fellow eye group and normal control group (all at P＜0.05) , and the thickness value of levator aponeurosis was significantly reduced in the severe blepharoptosis group compared with the moderate blepharoptosis group (P＜0.05).Pathological examination showed arranging disorder of muscle fibers,hyaline-like degeneration, connective tissue hyperplasia and interruption of endomysium.The number of eyes with severe hyaline-like degeneration and connective tissue hyperplasia was significantly increased in the severe blepharoptosis group than that in the moderate blepharoptosis group or the mild blepharoptosis group, as well as in the moderate blepharoptosis group than that in the mild blepharoptosis group(all at P＜0.01).The adipose cells in muscle in the mild blepharoptosis group, moderate blepharoptosis group and severe blepharoptosis group were (12.35±4.62), (17.58±7.46) and (26.19±10.81)/field,and adipose cells in the severe blepharoptosis group were significantly more than those in the mild and moderate blepharoptosis groups (t =5.60, P =0.00;t =2.71, P =0.01).A significant increase in the adipose cells also was seen in the moderate blepharoptosis group compared with the mild blepharoptosis group (t =2.44, P =0.02).Conclusions UBM can offer accurate thickness data of levator aponeurosis.The combination of thickness data and shifting range measurement of levator aponeurosis is helpful for the evaluation of muscle strength.The development of levator aponeurosis appears to be abnormal in congenital blepharoptosis patients.The histopathological change parallels to the severity of the disease.

Clinical efficacy of combined procedures for the surgical correction of congenital ptosis accompanied by epicanthus / 中华医学美学美容杂志

Objective To observe the effects of combined surgeries for the correction of congenital ptosis accompanied by epicanthus.Methods 80 cases (105 eyes) of congenital ptosis were analyzed in this study.64 cases (80 eyes),with levator muscle strength more than 4 mm,were treated with suspension of frontal aponeurosis,and 16 cases (25 eyes),with levator muscle strength less than 4 mm,were treated with shorten operation of levator palpebrae superioris.Furthermore,all these patients were corrected the epicanthus at the same time.Results Except the under correction in 5 cases (8 eyes),the remaining patients were corrected satisfactorily.Postoperative palperbal fissure length was averagely increased by 2.0± 1.0 mm,inner canthic diameter was averagely decreased by 4.0± 2.0 mm,the eyelid height was increased by average 9.0±1.0 mm,the inclination of palpebral fissure was 12.0°±2.0°;64 cases (80 eyes) were treated with suspension of frontal aponeurosis,postoperative recurrence were 7.5％ (6/80),no postoperative recurrence were 92.5％ (74/80),complication were 5.0％ (4/80);16 cases (25 eyes) were treated with shorten operation of levator palpebrae superioris,postoperative recurrence were 8.0％ (2/25),and no postoperative recurrence were 8.0％ (2/25);complication rates were 4.0％ (1/25).Conclusions This procedure of combined surgeries can reduce the recurrence rate effectively.Moreover,the satisfactory,functional,and aesthetic results can be obtained simultaneously with this method.

Unusual Path of Branches of Ilioinguinal Nerve: A Clinically Important Anatomic Variant

Ilioinguinal nerve is a collateral branch of lumbar plexus. Its anatomical variations in relation to adjacent musculoaponeurotic structures play a crucial role in the development of neuropathies associated with lower abdominal surgeries. In this report, we present a rare case of unusual course and branches of the ilioinguinal nerve, in a 55-year-old male cadaver. In the lateral part of inguinal canal ilioinguinal nerve gave three branches. Two of its branches pierced the external oblique aponeurosis, about 6 cm above the pubic symphysis, to supply the skin of the lower part of the anterior abdominal wall. Another branch pierced the conjoint tendon, in the medial part of the inguinal canal about 2 cm above the superficial inguinal ring. Knowledge of unusual path of these branches may be important to avoid injuries during the surgical repair of groin hernias. Further care should be taken while dealing with the conjoint tendon in the Bassini procedure.
