    Abstract Children with congenital disorders are unfortunate collateral victims of wars and natural disasters. Improved diagnosis could help organize targeted medical support campaigns. Patient identification is a key issue in the management of life-threatening conditions in extreme situations, such as in oncology or for diabetes, and can be challenging when diagnosis requires biological or radiological investigations. Dysmorphology is a central element of diagnosis for craniofacial malformations, with high sensibility and specificity. Massive amounts of public data, including facial pictures circulate daily on news channels and social media, offering unique possibilities for automatic diagnosis based on facial recognition. Furthermore, AI-based algorithms assessing facial features are currently being developed to decrease diagnostic delays. Here, as a case study, we used a facial recognition algorithm trained on a large photographic database to assess an online picture of a family of refugees. Our aim was to evaluate the relevance of using an academic tool on a journalistic picture and discuss its potential application to large-scale screening in humanitarian perspectives. This group picture featured one child with signs of Apert syndrome, a rare condition with risks of severe complications in cases of delayed management. We report the successful automatic screening of Apert syndrome on this low-resolution picture, suggesting that AI-based facial recognition could be used on public data in crisis conditions to localize at-risk patients.

    Abstract Aim and scope: The prevalence of increased intra-cranial pressure (ICP) in patients with scaphocephaly is controversial. Here, based on anthropological material, we aimed to determine whether adults with non-operated sagittal synostosis show indirect signs of increased ICP.
    Materials and methods: Thirty-eight dry skulls (21 skulls with sagittal craniosynostosis and 17 controls) were selected from the collections of the National Museum of Natural History (Paris, France). All skulls registered as 'fused sagittal suture' or 'scaphocephaly' in the registry of the Museum were included. All had total fusion of the sagittal suture. Controls were selected within skulls of similar origin (France), without visible craniofacial anomalies. The 38 skulls were CT-scanned using a standard medical CT-scan with a protocol dedicated to dry bone imaging. Eight radiological signs associated with raised ICP were assessed: (1) calvaria and (2) skull base thinning, (3) dorsum sellae erosion, (4) sella turcica lengthening, (5) copper beaten skull, (6) suture diastasis, (7) persistent metopic suture, and (8) small frontal sinus. Scaphocephaly was assessed based on head circumference, cranial index, intra-cranial volume, fronto-nasal angle, and inter-zygomatic distance. Linear and non-linear logistic models were used to compare groups.
    Results: 19/21 skulls with sagittal synostosis were significantly scaphocephalic. None of the criteria for ICP were significantly different in skulls with scaphocephaly relative to controls. Nevertheless, 5 individual skulls with scaphocephaly had ≥ 3 signs in favor of a history of raised ICP. We do not report the significant prevalence of indirect signs of raised ICP in adults with scaphocephaly. These results do not allow ruling out a history of early raised ICP or of minor prolonged raised ICP. Even though our findings support the fact that scaphocephaly is not significantly associated with prolonged raised ICP, individual cases (5/21) with clear signs in favor of a history of brain compression indicate that scaphocephaly correction should be considered as a functional procedure until the production of clear evidence. Cognitive assessments of non-operated adult patients with scaphocephaly could contribute to tackle this recurring question in craniofacial surgery.

    Abstract Background: Velopharyngeal insufficiency persists in 15 to 30% of children with cleft palate, despite early velar surgery. Pharyngoplasty using a superior pedicle flap is the most common secondary surgery to treat velopharyngeal insufficiency. This study aims to identify the criteria leading to indicate velopharyngoplasty in 3 groups of age.
    Materials and methods: we conducted a retrospective single center study in the reference center for cleft palate in Paris from 2013 to 2016. We included 61 children with non-syndromic cleft operated on with a velopharyngoplasty for velopharyngeal insufficiency. Pre-operative speech and surgical assessments, as well as the operative reports of the children, were analyzed retrospectively using multivariate models.
    Results: We included 61 patients. The only criteria factor for an early velopharyngoplasty was the Pittsburgh Weighted Speech Scale (PWSS) score (OR 1.20, CI 95% 1.07 to 1.4 ; P=.006). Criteria for a late velopharyngoplasty were a degradation of the velopharyngeal function (OR 16.07, CI 95% 1.7 to 518.7 ; P=.041) and lost of follow-up (OR 5.78, CI 95% 3.9 to 4320 ; P=.017).
    Conclusion: Criteria for early and late velopharyngoplasty were identified, and we demonstrated the insufficiency of Borel-Maisonny classification for scientific clinical study.

    Abstract Objective: Newborns with congenital hypogonadotropic hypogonadism (CHH) have an impaired postnatal activation of the gonadotropic axis. Substitutive therapy with recombinant gonadotropins can be proposed to mimic physiological male mini-puberty during the first months of life. The aim of this study was to compare the clinical and biological efficacy of two treatment modalities of gonadotropins administration during mini-puberty in CHH neonates.
    Design: Multicenter retrospective analytical epidemiological study comparing two treatments, pump vs injection, between 2004 and 2019.
    Methods: Clinical (penile size, testis size, testicular descent) and biological parameters (serum concentrations of testosterone, anti-Müllerian hormone (AMH) and Inhibin B) were compared between the two groups by multivariate analyses.
    Results: Thirty-five patients were included. A significantly higher increase in penile length and testosterone level was observed in the injection group compared to the pump group (+0.16 ± 0.02 mm vs +0.10 ± 0.02 mm per day, P = 0.002; and +0.04 ± 0.007 ng/mL vs +0.01 ± 0.008 ng/mL per day, P = 0.001). In both groups, significant increases in penile length and width, testosterone, AMH, and Inhibin B levels were observed, as well as improved testicular descent (odds ratio of not being in a scrotal position at the end of treatment = 0.97 (0.96; 0.99)).
    Conclusions: Early postnatal administration of recombinant gonadotropins in CHH boys is effective in stimulating penile growth, Sertoli cell proliferation, and testicular descent, with both treatment modalities.

    Abstract Objective: Here we trained an automatic phenotype assessment tool to recognize syndromic ears in two syndromes in fetuses-=CHARGE and Mandibulo-Facial Dysostosis Guion Almeida type (MFDGA)-versus controls.
    Method: We trained an automatic model on all profile pictures of children diagnosed with genetically confirmed MFDGA and CHARGE syndromes, and a cohort of control patients, collected from 1981 to 2023 in Necker Hospital (Paris) with a visible external ear. The model consisted in extracting landmarks from photographs of external ears, in applying geometric morphometry methods, and in a classification step using machine learning. The approach was then tested on photographs of two groups of fetuses: controls and fetuses with CHARGE and MFDGA syndromes.
    Results: The training set contained a total of 1489 ear photographs from 526 children. The validation set contained a total of 51 ear photographs from 51 fetuses. The overall accuracy was 72.6% (58.3%-84.1%, p < 0.001), and 76.4%, 74.9%, and 86.2% respectively for CHARGE, control and MFDGA fetuses. The area under the curves were 86.8%, 87.5%, and 90.3% respectively for CHARGE, controls, and MFDGA fetuses.
    Conclusion: We report the first automatic fetal ear phenotyping model, with satisfactory classification performances. Further validations are required before using this approach as a diagnostic tool.

    Abstract Primary mandibular reconstruction after tumor removal or osteoradionecrosis treatment is a standard procedure. The most common reconstruction techniques are fibula, scapula, and iliac crest free flaps. Nevertheless, all patients are not eligible for microsurgery. In this study, we assess 12 years of mandibular reconstruction using an osteo-muscular dorsal scapular pedicled flap (OMDS). We included 40 patients operated on using an OMDS flap. We collected parameters such as length of hospital stay, recurrence risk, and need for secondary flap for oral cutaneous fistula (OCF) treatment. Flap bone volume was assessed by segmenting the scapula on postoperative CT-scans using dedicated software. Forty patients were included. Indications for OMDS flaps were severe cardiovascular history (27%), preoperative radiotherapy with a radiation neck and potentially unreliable blood vessel sutures (20%), previous fibula free flap failure (15%), and patient refusing free tissue transfer (8%). Aside from these medical indications, OMDS flaps were performed in 30% of cases due to organizational concerns. The mean flap length was 73±16 mm, with a maximum of 109 mm. Flap bone volume was stable over time, with negligible resorption (p = 0.761). Secondary pedicled flaps were used to treat OCF in 5 patients (12%). Secondary esthetic procedures were performed in 9 patients (22%). None of the 40 flaps were removed. None of the patients had long-term scarring complications in donor sites. OMDS flaps merit consideration for mandibular reconstruction when free tissue transfer is contraindicated or impossible due to organizational issues.

    Abstract Here we provide a literature review of all the methods reported to date for analyzing 2D pictures for diagnostic purposes. Pubmed was used to screen the MEDLINE database using MeSH (Medical Subject Heading) terms and keyworks. The different recognition steps and the main results were reported. All human studies involving 2D facial photographs used to diagnose one or several conditions in healthy populations or in patients were included. We included 1515 articles and 27 publications were finally retained. 67% of the articles aimed at diagnosing one particular syndrome versus healthy controls and 33% aimed at performing multi-class syndrome recognition. Data volume varied from 15 to 17,106 patient pictures. Manual or automatic landmarks were one of the most commonly used tools in order to extract morphological information from images, in 22/27 (81%) publications. Geometrical features were extracted from landmarks based on Procrustes superimposition in 4/27 (15%). Textural features were extracted in 19/27 (70%) publications. Features were then classified using machine learning methods in 89% of publications, while deep learning methods were used in 11%. Facial recognition tools were generally successful in identifying rare conditions in dysmorphic patients, with comparable or higher recognition accuracy than clinical experts.

    Abstract Background: Head and neck spindle cell carcinoma (HNSpCC) is a rare histological variant associated with worse outcomes. Our objective was to identify clinicopathological factors associated with survival in patients with HNSpCC compared to patients with conventional head and neck squamous cell carcinoma (HNSCC).
    Methods: Using clinical data from the Surveillance, Epidemiology, and End Results database, we performed a survival analysis in patients with HNSpCC or HNSCC between 2004 and 2016.
    Results: A total of 458 HNSpCC and 77 104 HNSCC were identified, including 17% and 16% female, respectively. Five-year disease-specific survival (DSS) was 63.90% and 73.90% in patients with HNSpCC and HNSCC, respectively. Sex (hazard ratio [HR] for females = 2.816; CI: 1.139-6.965; p = 0.025) was significantly associated with DSS in HNSpCC while no association was observed between sex and DSS in HNSCC.
    Conclusion: HNSpCC in women is a specific subgroup of HNSCC, which is associated with a poor prognosis.

    Abstract Intentional skull deformations have been practiced by every human population, from the prehistoric times until the XXth century. In Europe, they were specifically prevalent in the region of Toulouse, France. The soft-tissue modifications due to such practices are not well characterized in the literature due to the rarity of photographic data. Most studies on skull deformations are thus based on skeletal remains. Here we performed a controlled geometric morphometric assessment of 31 frontal pictures and 70 lateral pictures of individuals from Toulouse with intentional deformations extracted from two XIXth century historical French photographic archives. We also measured the forces exerted on the skull vault by the traditional deformation device from Toulouse using a 3D-printed skull and pressure sensors. We showed that individuals with Toulouse deformations have distinctive facial features, caused by moderate forces exerted on the skull vault. Our results exhibit and quantify for the first time the real face of intentional skull deformations, which are a ubiquitous and distinctive feature of the human species.
