Augmented vertical rectus transpositions: Intraoperative measurement of torsion following sequential muscle detachment
No full textIntroduction: After vertical recti transposition surgery, a torsional change may occur. We hypothesized that step-by-step monitoring of the intraoperative torsional position of the eye can avoid any unexpected complications and identify critical moments of surgery that may have adverse effects. Methods: Nine patients with sixth nerve palsy that underwent complete transposition of the superior (SR) and inferior rectus (IR) muscles to the lateral rectus muscle by means of the technique of augmented vertical recti transposition were prospectively included. The torsional position of the eye was recorded at eight stages of the procedure. Results: We observed two distinct patterns of induced torsional deviation during partial disinsertion of a vertical rectus muscle depending on whether disinsertion began medially or laterally, after cutting about 3/4 of the muscle fibers: 3⁄4 nasal disinsertion of the SR and 3⁄4 temporal disinserton of the IR caused intorsion, 3⁄4 temporal disinsertion of the SR and 3⁄4 nasal disinsertion of the IR caused extorsion. Torsion improved after the vertical rectus was attached temporally to the sclera along the spiral of Tillaux with tying of the augmentation suture to the LR. The greatest change in torsion was from 3⁄4 temporal disinsertion of the SR (5°extorsion), to reattachment along the spiral of Tillaux temporally (5°intorsion). Conclusion: The SR and IR have different torsional effects, which only appears when more than half of the fibers are detached. Augmented transposition does not cause any additional torsional effects. This intraoperative monitoring system can be used to detect unintended torsional complications, especially during transposition surgery
Exogenous Lipoid Pneumonia due to Chronic Inhalation of Oily Product Used as a Lubricant of Tracheotomy Cannula
No full textExogenous lipoid pneumonia (ELP) is caused by the inhalation of vaporized oily products. Long-term exposure can result in chronic disease, whereas acute form usually results from massive aspiration of fatty substances. It has an incidence of 1.0%-2.5%. In case of symptomatic patients, the clinical presentation mainly includes acute or chronic respiratory symptoms such as dyspnea, fever, cough and less frequently chest pain, hemoptysis, or weight loss. Radiological findings are often aspecific or misinterpreted, and ELP is sometimes misdiagnosed as a malignancy of the lungs. Patient history and radiological findings can lead to a suspicion of ELP, but histological microscopic findings of intra-alveolar lipid and lipid-laden macrophages are required to confirm the diagnosis The mainstay of treatment consists of avoiding ongoing exposure and providing supportive care as repeated whole-lung lavage, corticosteroids, and/or immunoglobulins. Surgery is reserved for cases of high suspicion of cancer or serious clinical impact (as recurrent infections). Prognosis is benign, even if it has been reported cases of progression to severe respiratory failure, cor pulmonale, superinfection, and association with lung cancer. Here, we describe a case of ELP due to chronic inhalation of oily product (Vaseline) used as a lubricant of tracheotomy cannula
Asymmetric superior oblique split Z-tendon lengthening for face turn in bilateral asymmetric superior oblique overaction and exotropia
No full textIntroduction: The aim was to evaluate the effectiveness of the procedure of the superior oblique split Z-tendon lengthening to collapse A pattern and treat face turn in a cohort of patients with both incomitant intermittent exotropia and a vertical deviation associated with a bilateral asymmetric superior oblique overaction. Methods: We retrospectively reviewed the clinical records of patients with facial turn associated with intermittent exotropia and bilateral asymmetric superior oblique overaction, who underwent superior oblique muscle split tendon lengthening and concurrent horizontal surgery between 2009 and 2017. Results: A total of eight patients met the inclusion criteria. The preoperative average face turn was 26.8° (range, 20°–5°), and it significantly improved to 5.4° (range, 2°–8°) (p < 0.05). All the patients showed an improvement in the face turn with neutralization of the vertical deviation. The vertical deviation in the right gaze for the patient with a right turn and the left gaze in patients with left turn improved significantly (values of p < 0.05). Conclusion: The superior oblique split Z-tendon lengthening was an effective procedure to collapse the A pattern and the treatment of the face turn in a cohort of patients with both incomitant intermittent exotropia and a vertical deviation associated with a bilateral asymmetric superior oblique muscle overaction with less complications, and less varying results

No full textInferior rectus pulled-in-two syndrome: Surgical results after anterior and nasal transposition of the inferior oblique muscle
No full textPulled-in-two syndrome (PITS) is a serious intraoperative complication of strabismus surgery in which an extraocular muscle manipulated during the procedure is ruptured and potentially lost. Usually, there is a systemic or local condition that determines muscle weakness when put under tension. If the proximal portion of the broken muscle can be found, it can be reattached to the ocular globe or remaining muscle. If this is not possible, there are multiple varying approaches. We present three cases of PITS of the inferior rectus muscle, treated with good results with anterior and nasal transposition of the inferior oblique muscle. We propose this surgery as another potential technique if the muscle can not be retrieved
Yokoyama procedure efficacy on non-highly myopic patients with acquired esotropia and hypotropia
No full textObjective: To assess the efficacy of “Yokoyama Procedure,” on non-highly myopic patients with acquired esotropia and hypotropia. Methods: The study involved 10 eyes of 5 patients with eso-hypotropia. Inclusion criteria were acquired esotropic-hypotropic strabismus with lateral rectus inferior displacement and superior rectus nasal displacement confirmed by magnetic resonance imaging, refractive errors between ±6 D, and axial length < 27 mm. Range of full duction movements and maximum angles of abduction-sursumduction was measured in each eye before and after surgery. All patients underwent T1- and T2-weighted magnetic resonance imaging. The surgery was aimed at creating a junction between the muscle bellies of the superior and lateral rectus muscles. This junction was made approximately 14 mm behind the insertions using a non-absorbable mersilene 5/0 suture (Yokoyama procedure). Results: Mean patient age was 64.8 ± 4.8 years. The mean globe axial length was 25.4 ± 0.76 mm and a mean corresponding spherical equivalent refraction of −3.7 ± 1.7 D was observed. Eight eyes on 10 had mild limitation in abduction, while the remaining 2 had no limitation. Three out of 10 eyes showed a moderate limited sursumduction, 5 eyes were categorized as mild, and the remaining 2 had no limitation. No evident post-operative limitation was present in any eye, in both abduction and sursumduction (p < 0.01). Pre-operative esotropia and hypotropia were, respectively, 32 ± 11 prismatic diopters and 25 ± 5 prismatic diopters, and they were significantly reduced after surgery as 9 ± 1.7 prismatic diopters and 6 ±1 prismatic diopters (p = 0.043), respectively. Conclusion: Yokoyama procedure is an effective, fast, reversible procedure to face eso-hypotropic acquired strabismus, even in patients with a clear magnetic resonance imaging displacement of superior and lateral rectus muscles, and absence of globe dislocation and of elevated myopia
