RESUMEN
With the rise of risk prevention surgery, more and more bilateral mastectomies are performed. These present a challenge when patients desire autologous reconstruction. Some surgeons perform reconstructions using a double DIEP flap, but this technique, which requires rapid operation and extensive experience, can sometimes be difficult to implement. Other factors may also favor a two-stage reconstruction, one breast after the other. We present here our technique to harvest two hemi-DIEP during two distinct operating times, by modifying the design of the first flap and by performing a prior autonomization of the second.

INTRODUCTION: Synkinesis is a disabling sequelae of facial palsy, which worsens facial asymmetry and diminishes the patients' quality of life. Their physiopathology is partially known, but cannot explain all the synkinesis. MATERIAL AND METHODS: We report a literature review of the state of the art concerning the knowledge on synkinesis physiopathology, as well as their management. RESULTS: It is accepted that the physiopathological mechanism of synkinesis is mixed. The phenomena of cerebral plasticity, aberrant nerve regrowth, hyperexcitability of the facial nerve nucleus and ephaptic nerve transmission, have been observed. We propose a new physiopathological hypothesis: synkinesis could be the consequence of latent circuits activation, preexisting in the healthy subject. We could propose three potential latent circuits: physiological synergistic contractions, adjacent motor units recruitment, and reactivation of remote latent circuits for function compensation. The treatment options are multiple, dominated by chemodenervation, whose effectiveness is undeniable. Rehabilitation has also proven its effectiveness, particularly with feedback techniques. Finally, surgery helps with these options. However, the indications of the different treatments remain to be codified. CONCLUSION: The validation of our physiopathological hypothesis would allow a better understanding and a better screening of synkinesis, in order to propose a more adapted treatment.

PURPOSE: To evaluate incidence of posterior capsule opacification requiring Nd:YAG capsulotomy over 3 years in a large series of eyes implanted with the enVista® MX60 Intraocular Lens (IOL). METHODS: A university-based, single-center, observational study of patients' medical records was conducted. Uneventful cataract surgery patients with in-the-bag implantations of the enVista® MX60 IOL with a minimum of 24 months follow-up were included in the study. Exclusion criteria were insufficient follow-up (<24 months), intraoperative complications and combined surgery. The primary outcome measure was rate of YAG laser capsulotomy, while secondary outcome measures were time to YAG laser capsulotomy and rate of glistenings. RESULTS: A total of 245 eyes of 143 patients received the MX60 IOL and were followed in the same center. Of these, 226 eyes were included in the study. Mean age was 80.7±8.3 years and M/F ratio was 42/101 (29.4/70.6%). The mean preoperative distance (logMAR) visual acuity was 0.67±0.5, while postoperatively it was 0.31±0.5 and 0.32±0.5 at the last visit. The Mean±SD follow-up time (min-max) was 35.2±7.2, (24-48.4) months. The incidence of Nd:YAG capsulotomy over 3 years was 5/226 (2.2%). Average time between surgery and Nd:YAG capsulotomy was 32.17 months. Univariate analysis of age, gender, presence of comorbidity and baseline visual acuity found no predictive factors for capsulotomy. No glistenings were reported at any postoperative visit. CONCLUSION: The three-year cumulative incidence of PCO requiring Nd:YAG laser capsulotomy was 2.2% for the enVista® MX-60 IOL, with no glistenings observed during follow-up. This low rate confirms the excellent safety profile of this IOL.
