BACKGROUND Several modifications of the classic retromuscular Stoppa technique to facilitate dissection beyond the lateral border of the rectus sheath recently were reported. We describe a novel technique of transversus abdominis muscle release (TAR) for posterior component separation during major abdominal wall reconstructions. METHODS Retrospective review of consecutive patients undergoing ...

OBJECTIVE Establish criteria for the diameters of normal extraocular muscles using computerized tomography in a Thai population. MATERIAL AND METHOD Diameters of extraocular muscles (medial, lateral, superior complex, and inferior rectus) were calculated for 200 patients on coronal direction of screening paranasal sinuses. The effects of age and sex were also analyzed. RESULT Normal ranges ...

PURPOSE To analyze the histologic features of the insertion of the medial and the lateral rectus muscles in humans. METHODS Postmortem study performed on 49 extraocular muscles from 21 subjects without known ocular disease. All muscles were obtained no longer than 8 hours after death, after consent for autopsy. Thirty-seven lateral recti muscles and 12 medial recti muscles were studied with l...

Eye muscle fibers can be divided into two categories: nontwitch, multiply innervated muscle fibers (MIFs), and twitch, singly innervated muscle fibers (SIFs). We investigated the location of motoneurons supplying SIFs and MIFs in the six extraocular muscles of monkeys. Injections of retrograde tracers into eye muscles were placed either centrally, within the central SIF endplate zone; in an int...

Some patients with large-angle strabismus may refuse or may not meet the criteria for binocular surgical correction. A second option for these patients involves a monocular procedure, which can be performed under peribulbar anesthesia and offers certain advantages (1). Improved surgical outcomes for conventional procedures may enhance the effectiveness of monocular surgery. In theory, this enha...

IMPORTANCE Extraocular muscle strengthening is a common treatment for strabismus. Plication is an alternative procedure for strengthening muscles with less tissue trauma than resection. OBJECTIVE To compare the surgical dose effect of plication with that of resection. DESIGN, SETTING, AND PARTICIPANTS Retrospective comparison of surgical outcomes in an academic pediatric ophthalmology and s...

To the Editors: Acquired progressive esotropia in patients with high myopia1 is caused by conversion of lateral rectus muscle function from abduction to infraduction, leading to impaired abduction and supraduction.2 Imaging techniques have revealed abnormal extraocular muscle position in these patients; the lateral rectus muscle is displaced inferiorly and the superior rectus muscle is shifted ...

Aims. To report the results of lateral rectus muscle recession, medial rectus muscle resection, and superior oblique muscle transposition in the restoration and maintenance of ocular alignment in primary position for patients with total third-nerve palsy. Methods. The medical records of patients who underwent surgery between March 2007 and September 2011 for total third-nerve palsy were reviewe...

INTRODUCTION We report on a case of isolated metastatic breast cancer to the medial rectus muscle. This entity is exceedingly rare. CASE A 44-year-old female with a history of breast cancer presented with unilateral maxillary symptoms and was treated for sinusitis. Over time, she developed ocular pain, diplopia, blurred vision and eventually complete adduction deficit. RESULTS T1-weighted m...

The extraocular muscles are responsible for all eye movements required to track and fix objects. Superior rectus muscle is located in the superior level of orbital cavity, below musculus levator palpebrae superioris , tilted slightly lateral part orbit. In a routine dissection, we found left, unilateral variation with no other structures, such as nerves vessels. abnormal presented two parts - m...
