IntroductionLe pectus excavatum est la malformation congénitale thoracique la plus fréquente et constitue un motif de consultation courant en chirurgie plastique. Notre attitude consiste le plus souvent en un comblement de la dépression par une prothèse sur mesure en silicone. L'objectif de ce travail était d'évaluer les gains apportés par la conception assistée par ordinateur (CAO) dans la fabrication des implants en comparaison de la méthode classique de moulage plâtré.Patients et méthodeNous avons colligé l'ensemble des cas ayant bénéficié de la mise en place d'implants sur mesure en silicone au sein du service de chirurgie plastique du CHU de Nantes. Les critères de jugement étaient la qualité des résultats évaluée par le patient, et par l'équipe chirurgicale en aveugle sur photographies et par questionnaires standardisés. Les délais pré-opératoires, les durées d'interventions et d'hospitalisation, le nombre de reprises chirurgicales à visée cosmétique, les suites et complications postopératoires, étaient relevés.RésultatsEntre 1990 et 2016, 29 implants thoraciques en silicone ont été posés dans notre service. Avant 2012, les implants étaient conçus par moulage plâtré (n=13). Après cette date, les implants étaient conçus par CAO (n=16). Les patients jugeaient leurs résultats « bons » ou « excellents » dans 77 % et 86 % des cas respectivement dans les groupes Plâtre et CAO. Les notes attribuées par l'équipe chirurgicale aux reconstructions par implants CAO étaient meilleures que dans le groupe Plâtre : 8,17 versus 6,96 (p=0,001). Les implants CAO étaient significativement moins perceptibles que les implants du groupe Plâtre. La durée opératoire était réduite dans le groupe CAO : 60,2 versus 74,7minutes dans le groupe Plâtre (p=0,04), de même que la durée d'hospitalisation : 3,5 versus 5,3jours (p=0,01). Il n'y avait pas de différences significatives entre les deux groupes en termes de complications postopératoires.ConclusionLa prise en charge des pectus excavatum par pose d'un implant en silicone sur mesure constitue une méthode peu invasive et pourvoyeuse de bons résultats cosmétiques. La conception de ces implants est facilitée et améliorée qualitativement par la CAO.IntroductionPectus excavatum is the most common congenital chest malformation and is a common reason for consultation in plastic surgery. Our attitude is most often a filling of the depression with a custom-made silicone prosthesis. The objective of this work was to evaluate the interest of computer-aided design (CAD) of implants compared to the conventional plaster molds method.Patients and methodsWe have collected all the cases of custom-made silicone implants to treat funnel chests in our plastic surgery department. The quality of the results was evaluated by the patient, and in a blind manner by the surgical team using photographs and standardized surveys. The pre-operative delays, the operating time and length of hospital stays, the number of surgical recoveries, and the post-operative surgical outcomes were recorded.ResultsBetween 1990 and 2016, we designed 29 silicone thoracic implants in our department. Before 2012, implants were made from plaster chest molds (n=13). After this date, implants were designed by CAD (n=16). Patients rated their results as "good" or "excellent" in 77% and 86% of cases respectively in the plaster and CAD groups. The surgical team's ratings for CAD implant reconstructions were better than in the plaster group: 8.17 versus 6.96 (P=0.001). CAD implants were significantly less detectable than the plaster group implants. The operating time was reduced in the CAO group: 60.2 compared to 74.7minutes in the plaster group (P=0.04), as was the length of hospitalization: 3.5 versus 5.3 days (P=0.01). There were no significant differences between the two groups in terms of post-operative complications.ConclusionThe management of pectus excavatum by a custom-made silicone implant is a minimally invasive method that provides good cosmetic results. The design of these implants is facilitated and qualitatively improved by CAD.
