RESUMO
INTRODUCTION: Typically, the axillary arch is defined as a fleshy slip running from latissimus dorsi to the anterior aspect of the humerus. Phylogeny seems to give the most relevant and plausible explanation of this anatomical variant as a remnant of the panniculus carnosus. However, authors are not unanimous about its origin. We report herein the incidence of axillary arch in a series of 40 human female dissections and present an embryologic and a comparative study in three domestic mammals. MATERIALS AND METHODS: Forty formalin-preserved Caucasian human female cadavers, one rat (Rattus norvegicus), one rabbit (Oryctolagus cuniculus) and one pig (Sus scrofa domesticus) cadavers were dissected bilaterally. A comparative, analytical and a descriptive studies of serial human embryological sections were carried out. RESULTS: We found an incidence of axillary arch of 2.5% (n = 1 subject of 40) in Humans. We found a panniculus carnosus inserted on the anterior aspect of the humerus only in the rat and the rabbit but not in the pig. The development of the latissimus dorsi takes place between Carnegie stage 16-23, but the embryological study failed to explain the genesis of the axillary arch variation. However, comparative anatomy argues in favour of a panniculus carnosus origin of the axillary arch. CONCLUSIONS: With an incidence of 2.5% of cases, the axillary arch is a relatively frequent variant that should be known by clinician and especially surgeons. Moreover, while embryology seems to fail to explain the genesis of this variation, comparative study gives additional arguments which suggest a possible origin from the panniculus carnosus.

BACKGROUND: The national ranking examination (NRE) marks the end of the second cycle (6th university year) of French medical studies and ranks students allowing them to choose their specialty and city of residency. We studied the potential predictive factors of success at the 2015 NRE by students attending a French School of Medicine. METHODS: From March 2016 to March 2017, a retrospective study of factors associated with the 2015 NRE success was conducted and enrolled 242 students who attended their sixth year at the school of medicine of Reims. Demographic and academic data collected by a home-made survey was studied using univariate and then multivariate analysis by generalized linear regression with a threshold of p < 0.05 deemed significant. RESULTS: The factors independently associated with a better ranking at the NRE were the motivation for the preparation of the NRE (gain of 3327 ± 527 places, p < 0.0001); to have participated in the NRE white test organized by la Revue du Praticien in November 2014 (gain of 869 ± 426 places, p < 0.04), to have participated in the NRE white test organized by la conférence Hippocrate in March 2015 (+ 613 places ±297, p < 0.04). The factors independently associated with poor NRE ranking were repeating the first year (loss of 1410 places ±286, p < 0.0001), repeating a year during university course (loss of 1092 places ±385, p < 0.005), attendance of hospital internships in 6th year (loss of 706 places ±298, p < 0.02). CONCLUSIONS: The student motivation and their white tests completion were significantly associated with success at the NRE. Conversely, repeating a university year during their course and attendance of 6th year hospital internships were associated with a lower ranking.

BACKGROUND: The volume of the profunda femoris artery perforator (PAP) flap limits its indications to small- and medium-sized breast reconstructions after modified radical mastectomy for cancer. We report a modified PAP flap design, including not only a vertical extension that increases its volume but also the skin surface, which suits larger breasts requiring immediate or delayed breast reconstructions and compare the results with our horizontal skin paddle PAP flap experience. PATIENTS AND METHODS: In our center between November 2014 and November 2016, 51 consecutive patients underwent a PAP flap breast reconstruction following breast cancer. A retrospective analysis on the collected data was performed to compare 34 patients with a bra cup smaller than C who underwent 41 horizontal PAP flap procedures, with those (n = 17) of a bra cup greater than or equal to C who underwent 21 fleur-de-lys PAP flap procedures. Demographic, anthropometric, flap and surgical characteristics, postoperative complication rates, and hospital stay were compared between the two groups. RESULTS: The average flap weight was 480 g (range: 340-735 g) for the fleur-de-lys PAP flap group compared with 222 g (range: 187-325 g) for the horizontal PAP flap procedure (p < 0.001). The mean flap dimensions were 25 × 18 cm for the fleur-de-lys PAP flap group compared with 25 × 7 cm in the horizontal PAP flap group. No flap failure was observed in the fleur-de-lys PAP flap group compared with two flap failures secondary to venous thrombosis in the horizontal PAP flap group (NS). Three patients (14%) experienced delayed healing at the donor site compared with four patients (10%) in the horizontal PAP flap group (NS). CONCLUSION: The fleur-de-lys skin paddle design not only allows an increase of the horizontal PAP flap volume, but also increases the skin surface, with an acceptable donor site morbidity. For medium- or large-sized breasts, the fleur-de-lys PAP flap seems to be ideal when a DIEP flap-based reconstruction is contraindicated.

PURPOSE: While anatomical variations of the subscapular vessels are frequently encountered during axillary dissection, little is found in the literature. The aim of this cadaveric study was to define arterial and venous anatomical variations and frequencies of the subscapular vascular pedicle and its terminal/afferent vessels in women. METHODS: We performed 80 dissections of the axillary region on forty female formalin-embalmed cadavers. Each anatomical arrangement was photographed and recorded on a scheme before analysis. RESULTS: We propose a new classification of the subscapular pedicle variations. We observed three types of subscapular arterial variation. The type Ia was the most frequent arrangement (71% of our dissections), the type Ib was observed in 11% and the type II in 18% of cases. We observed four types of subscapular venous variation. The type Ia was observed in 63% of cases, the type Ib in 14%, the type II in 14% and the type III in 10% of cases. CONCLUSIONS: This knowledge of the anatomical variation arrangement and frequencies of the subscapular vascular pedicle will assist the surgeon when dissecting the axillary region for malignant or reconstructive procedures.

Background: Venous anatomy of the digits and the hand is poorly reported in the literature compared to arterial anatomy. While knowledge of the venous anatomy is crucial to ensure safe skin incisions, skin flap design, or blood return restoration for digital replantations, data in anatomical and clinical textbooks are rather limited. The purpose of this anatomical study was to describe the venous anatomy of the digits and the hand. Method: Our series reports descriptive results from 10 non-embalmed hand dissections from 5 different corpses. Hands were previously co-injected by arteries followed by veins with a different colored latex before being dissected under optical magnification (x4). Each anatomical specimen was photographed before being analyzed. Results: Each injection revealed both arterial and venous vascular systems. Latex injections were a useful technique to show the dorsal, volar superficial, and deep venous system. There was a constant and reliable topographic vascular anatomy of the superficial venous system of the digits and hand. However, we could not observe a high density of dorsal superficial venous valves as previously reported. Conclusion: The knowledge of the arrangement of the venous system of the digits and the hand should help the surgeon when performing surgical procedures in the hand. The surgeon should take into consideration this venous anatomy when performing skin incisions, skin flaps, or replantation procedures which would preserve the normal venous physiology as much as possible.
RESUMO
BACKGROUND: Sequelae resulting from breast cancer negatively impact patients' quality of life. Although the deep inferior epigastric perforator (DIEP) flap has become a standard for autologous breast reconstruction, there are limited data regarding long-term quality of life. The authors studied patients' quality of life more than 5 years after DIEP flap breast reconstruction and compare it with two French reference samples. METHODS: A cross-sectional study of quality of life was performed in women who underwent DIEP flap breast reconstruction between 1995 and 2007 using the Medical Outcomes Study 36-Item Health Survey (Short Form-36). The first reference sample included subjects from the French general population (n = 3308), and the second included cancer survivors who underwent mastectomy with (n = 70) or without (n = 135) breast reconstruction. RESULTS: One hundred eleven respondents were analyzed among 186 eligible women. The mean follow-up period after reconstruction was 8.6 years (range, 5 to 15 years). There were no statistically significant differences in the quality of life between women from 45 to 64 years old who underwent DIEP flap breast reconstruction and from the French general population. Five of the eight Short Form-36 dimensions were significantly better in the DIEP flap breast reconstruction group in the 65- to 74-year-old cohort. In addition, quality of life of our study population was significantly higher than that of women who underwent mastectomy with or without any type of breast reconstruction. CONCLUSION: These results indicate that DIEP flap breast reconstruction allows patients with breast cancer to maintain a good postoperative quality of life comparable to that of the general population. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

IMPORTANCE: Otoplasty procedures usually involve cartilage sparing, with stitches or cartilage scoring. These techniques have been widely reviewed in the literature. The technique reported in this study requires neither stitches nor rasping but rather a complete separation of the helix and antihelix, with nontransfixing incisions to break the cartilaginous springs. OBJECTIVES: To evaluate the technical details, aesthetic results, and complications in a series of otoplasty procedures involving cartilage splitting without stitches. DESIGN, SETTING, AND PARTICIPANTS: We conducted a retrospective review of patients who underwent otoplasty procedures between January 2004 and September 2010, by the same senior surgeon. MAIN OUTCOMES AND MEASURES: File data on complications, recurrences, and revision rates were collected. An aesthetic evaluation of the postoperative results was conducted by a panel of 3 plastic surgeons and 3 lay observers. RESULTS: Our series included 58 patients, with a mean age of 16 years. No recurrences were reported. Six patients (10%) experienced minor complications. No revisions were needed. No chondritis or skin necrosis was noted. The aesthetic results were very good for 36 patients (62%) by the plastic surgeons and 39 patients (68%) by lay observers. The remaining aesthetic results were judged as good. CONCLUSIONS AND RELEVANCE: The Jost otoplasty procedure described herein requires no nonabsorbable sutures to bend the cartilage, avoiding many complications. The technique is safe, reliable, and reproducible, with predictable and permanent outcomes. It is also useful for secondary otoplasty after failed Stenström or Mustarde otoplasty. LEVEL OF EVIDENCE: 4.
