'Mini DC-F' in rhinoplasty: Diced cartilage and fascia grafts with the temporalis fascia dissected along its width - A technical note.

In rhinoplasty, diced cartilage with fascia (DC-F) is a commonly used technique to enhance dorsal projection and achieve a smooth dorsum. We have developed a modified technique by dissecting the thickness of the fascia along its width, called "Mini DC-F". This method allows for effective camouflaging of dorsal irregularities and provides a slight increase in dorsal height. This simplified and less invasive technique not only reduces operative time but also enhances the surgeon's ability to achieve a refined aesthetic result. This technique offers an intermediate option in the surgical arsenal, bridging the gap between pure camouflaging methods and those aimed at significant dorsal augmentation.

De l'histoire des chirurgiens cachés derrière nos instruments du quotidien. Partie 4 : la rhinoplastie.

Many surgical instruments are named after their inventors, acclaimed surgeons of the past, because of their discoveries and their contributions in the field of surgical techniques. However, these daily reminders of history of surgery are often forgotten by the modern practitioners. We propose to review, through a selection of instruments, short biographies of these precursors. This fourth original article will focus on the inventors of rhinoplasty instruments: Joseph, Killian, Aufricht, Cottle and Claoué.

A subperiosteal maxillary implant causing severe osteolysis.

Subperiosteal implant denture therapy was initially introduced in 1942 in Sweden and was subsequently used worldwide for the treatment of fully edentulous maxillary or mandibular arches with advanced bone atrophy. Most authors describe decent success rates for mandibular subperiosteal implants in cases with major bone atrophy but follow-up studies for maxillary subperiosteal implants are not available. Here, we report a case of severe maxillary osteolysis secondary to the placement of a subperiosteal in-house implant. Subperiosteal implants are rarely used today but patients still carrying these devices can be challenging to manage when severe complications occur. New technical advances, including the use of surgical planification and additive manufacturing, may lead to a new interest in subperiosteal implants.

Quantitative assessment of the learning curve for cleft lip repair using LC-CUSUM.

The first step in cleft lip repair is the precise positioning of anatomical landmarks and tracing of the incisions on the patient's lip at the beginning of the procedure. The aim of this study was to evaluate progress made in learning cleft lip repair tracing using a quantitative assessment of learning curves: LC-CUSUM (learning curve - cumulative sum). Eight surgical residents were enrolled and asked to trace lip repair incisions on five cases of unilateral left cleft lip over 5 consecutive weeks. Results were compared to a reference tracing based on the positioning of nine anatomical landmarks and assessed using LC-CUSUM. Competence was defined as the accurate positioning of the nine landmarks (less than 1.4mm deviation from the reference positions, with an accepted 15% failure rate). After five tracing sessions, competence was not achieved evenly for all trainees, or for all landmarks, underlining differences in inter-individual learning ability even with similar training. However, despite an initial marked lack of theoretical and practical training in lip repair techniques, repeated drawings of cleft lip incisions allowed a satisfactory level of competence to be reached for most landmarks and most trainees. Nevertheless it was found that not all landmarks are understood by students with similar ease, and that landmark positioning reveals significant inter-individual differences. This approach allowed a global assessment of the teaching of cleft repair and will help to focus training on specific problematic points for which competence was not obtained according to the LC-CUSUM test.
