BACKGROUND: Operative intervention to correct incisional hernia affects 150,000 patients annually, with 1 in 3 repairs recurring within 9 years. The aim of this study was to compare the incidence of incisional hernia and postoperative complications in elective midline laparotomy patients after the use of prophylactic mesh placement and primary suture closure. METHODS: A systematic review was performed to identify studies comparing prophylactic mesh placement to primary suture closure in elective, midline laparotomy at index abdominal aponeurosis closure...

BACKGROUND: The nose is a dangerous site for filler injection. This study investigated the anatomy of the dorsal nasal artery at the upper part of the nose to clarify how ocular complications occur. METHODS: Dissections were performed in 50 noses of the embalmed cadavers. Either the soft embalming or formaldehyde embalming processes were used. RESULTS: The dorsal nasal artery is not a constant artery. The artery traveled in the subcutaneous tissue layer of the nasal dorsum on the transverse nasalis muscle and its midline nasal aponeurosis which connected the muscles on both sides...

The aim of this study was to examine the superoinferior extension of the post-levator aponeurosis fat pad in the upper eyelids of Japanese cadavers. Twenty-six upper eyelids (12 right and 14 left) from 15 Japanese cadavers (6 men and 9 women; average age at death, 82.1 years) were used in this experimental anatomical study. After an orbital exenteration, the tissues were cut sagittally through the center of the orbit, and the superoinferior extension of the post-levator aponerosis fat pad was microscopically examined on the sections...

Musculoskeletal (dys-)function relies for a large part on muscle architecture which can be obtained using Diffusion-Tensor MRI (DT-MRI) and fiber tractography. However, reconstructed tracts often continue along the tendon or aponeurosis when using conventional methods, thus overestimating fascicle lengths. In this study, we propose a new method for semiautomatic segmentation of tendinous tissue using tract density (TD). We investigated the feasibility and repeatability of this method to quantify the mean fascicle length per muscle...

There exist several studies using morphological analyses of skeletal muscles to obtain a better understanding of muscle structure. The structural information obtained are primarily determined from single muscle components using individual animals of discrete ages. Further, little is known about changing dimensions of the aponeurosis, which is an important load-transferring interface in muscle mechanics. Thus, the aim of the present study was to determine how the muscle, tendon, and particularly the aponeurosis geometry of the rabbit shank musculature (M...

Takaki Sanada, Eiji Uchiyama
Repair of chronic Achilles tendon rupture is a surgical challenge. We describe the use of a free turndown tendon flap augmentation raised from the proximal gastrocnemius aponeurosis. To control optimal tension or the reconstructed Achilles tendon length, we used an original method by referring to the gravity planter flexion ankle angle of the contralateral limb. Key aspects of the technique are described. A retrospective analysis of the short-term outcomes achieved in a case series (n = 56) is presented. The postoperative anthropometric findings are also presented to indicate the successful outcomes achieved with this technique...

BACKGROUND: Double eyelidplasty has 3 key factors: motor power, connecting tissue, and skin adhesion. OBJECTIVE: To create natural double eyelid, new anatomy structure should be rebuilt according to physiological double eyelid in these 3 aspects. METHODS: Levator aponeurosis is used as "connecting tissue" to transmit dynamic "motor power" of levator muscle to upper eyelid, and "skin adhesion" is induced between levator aponeurosis and skin in a plane manner...

The damage control surgery, with emphasis on laparostomy, usually results in shrinkage of the aponeurosis and loss of the ability to close the abdominal wall, leading to the formation of ventral incisional hernias. Currently, various techniques offer greater chances of closing the abdominal cavity with less tension. Thus, this study aims to evaluate three temporary closure techniques of the abdominal cavity: the Vacuum-Assisted Closure Therapy - VAC, the Bogotá Bag and the Vacuum-pack. We conducted a systematic review of the literature, selecting 28 articles published in the last 20 years...

BACKGROUND: Oromandibular dystonia is a movement disorder that is characterized by involuntary masticatory and/or lingual muscle contracture. Jaw closing dystonia, the most common subtype of this condition, can cause trismus and is frequently misdiagnosed as temporomandibular joint disorder or masticatory muscle tendon-aponeurosis hyperplasia. MATERIALS AND METHODS: This report describes the long-term results of 18 patients with limited mouth opening (mean maximal mouth opening: 12...

BACKGROUND: Radiofrequency (RF) treatment is a minimally invasive procedure that has been used for more than 3 decades in treating various chronic pain syndromes. Conventional (continuous) RF treatment occasionally results in worsening or even initiating a new type of pain. The use of pulsed radiofrequency (PRF), which has a non- or minimally neurodestructive neuromodulatory effect, serves as an alternative to conventional RF therapy in many medical situations. OBJECTIVES: To evaluate the effect of applying PRF for 6 minutes vs...

Spigelian hernias are rare hernias, occurring through a defect in the Spigelian aponeurosis. Like other hernias, they may contain abdominal contents but are more likely to be incarcerated due to the small size of the fascial defect. Multiple intra-abdominal organs have reportedly been found in Spigelian hernias. A search of the literature showed only nine reported cases in which an appendix has been found within a Spigelian hernia. We present a patient with a history of lower abdominal pain since 10 weeks with a large intra-abdominal mass in the right iliac fossa...

REVIEW
Yvonne Cheung
Accessory muscles around the ankle are commonly encountered as incidental findings on cross-sectional imaging. Mostly asymptomatic, accessory muscles sometimes mimic mass lesions. They have been implicated as the cause of tarsal tunnel syndrome, impingement of surrounding structures, and chronic pain. Distinguishing these muscles can be challenging, because some travel along a similar path. This article describes these accessory muscles in detail, including their relationships to the aponeurosis of the lower leg...

BACKGROUND: Published data regarding the structure of the quadriceps tendon are diverse. Dissection of the quadriceps muscle group revealed that beside the rectus femoris, vastus lateralis, vastus intermedius and vastus medialis a fifth muscle component- named the tensor vastus intermedius consistently fused into quadriceps tendon. It can be hypothesized that all these elements of the extensor apparatus of the knee joint must also be represented in the quadriceps tendon. This study investigated the multi-layered quadriceps tendon with special emphasis on all components of the quadriceps muscle group including the newly discovered tensor vastus intermedius...

PURPOSE: Pentagonal wedge resection is a technique used to address a wide variety of eyelid pathology. This procedure frequently results in excess skin at the apex of the wound, commonly known as a "dog ear." A variety of methods have been described to address the cutaneous redundancy, the most classic of which is the Burow's triangle repair. The authors present a technique to address the anterior lamellar excess that avoids placement of a vertical scar traversing the pretarsal and preseptal portion of the affected eyelid...

We present a novel technique for the surgical management of sizeable medial upper eyelid colobomas that entails advancement of an ipsilateral upper lid flap sustained by a levator aponeurosis-Müller-conjunctiva pedicle and combined with a lateral semicircular flap from the affected lid. The technique was used in 4 consecutive pediatric patients of mean age 21.2 months and mean coloboma size 12.3 mm and resulted in sufficient cornea protection, rapid rehabilitation, and satisfying cosmesis.

BACKGROUND: Differential motion between the plantaris and Achilles tendons has been hypothesized to contribute to pain in some patients presenting with Achilles tendinopathy. However, objective evidence of differential Achilles-plantaris motion is currently lacking from the literature. OBJECTIVE: To determine whether differential, multidirectional motion exists between the plantaris tendon (PT) and Achilles tendon (AT) as documented by dynamic ultrasound (US) and postdissection examination in an unembalmed cadaveric model...
