Craniofacial Trauma of Equestrian Origin.

Horse riding is a popular yet dangerous sport, often resulting in facial traumas due to unpredictable horse reactions or falls. This retrospective study examines 20 patients. The aim of the study is to analyze maxillofacial traumas of equine origin and discuss prevention strategies. Conducted from 2004 to 2021 at our university hospital's emergency department in France, inclusion criteria encompassed patients with maxillofacial trauma admitted to the emergency department and referred to ENT and/or dentistry post-horse-related accidents. Patients were identified from the Health Data warehouse. While 35 medical files were accessed, 15 did not meet inclusion criteria. Analysis of patient parameters, including age, sex, injury date, circumstances, injury type, management, helmet usage, operative interventions, and potential sequelae, revealed a predominantly female population (16 versus 4) under 48 years old. Traumas were most prevalent in summer (80%) and frequently involved riders on foot (60%). Seventy percent of patients sustained at least 1 facial fracture, with helmet use documented in only 1 case. In conclusion, horse riding can lead to various traumas, often necessitating surgical intervention. Preventive measures such as protective helmets, even for nonmounted riders, are crucial as the literature highlights many injuries occurring due to helmet omission.

Ultrasound-guided hookwire localization of non palpable cervical lymphadenopathy: A case-control study of operative time.

OBJECTIVE: We aimed at evaluating the impact of ultrasound-guided (US) hookwire localization of nonpalpable cervical lymphadenopathy on operating time. DESIGN AND METHODS: Retrospective case control study (January 2017 and May 2021) of 26 patients with lateral nonpalpable cervical lymphadenopathy undergoing surgery with (H+) and without (H-) per operative US-guided hook-wire localization. Operative time (general anesthesiology onset, hookwire placement, end of surgery) and surgery-related adverse events data were collected. RESULTS: Mean operative time was significantly shorter in H+ group versus H- group (26 ± 16 min vs. 43 ± 22 min) (p = 0.02). Histopathological diagnosis accuracy was 100% versus 94% (H+ vs. H-, p = 0.1). No significant between group difference in surgery-related adverse events was reported (wound healing, p = 0.162; hematomas, p = 0.498; neoplasms removal failure, p = 1). CONCLUSION: US-guided hookwire localization of lateral nonpalpable cervical lymphadenopathy allowed a significant reduction in operative time, comparable histopathological diagnosis accuracy and adverse events compared with H-.

Mid-term outcomes of mastoid obliteration with biological hydroxyapatite versus bioglass: a radiological and clinical study.

PURPOSE: Radiological assessment of osseointegration of mastoid grafts: biological hydroxyapatite (Bio-Oss®) (BHA) versus bioglass S53P4 (Bonalive®) (BG). METHODS: Retrospective (10 ± 4 months post-surgery) monocentric high resolution computed tomography (CT) scan assessment (November 2018 and October 2020) by two independent radiologists (R1, R2), blinded to patient allocation. All patients who had undergone a total mastoid obliteration were eligible. Excluded: complications namely otological acute or chronic infections, unbalanced metabolic disease, long-term cortico-steroid therapy, auto-immune disease, history of allergy to grafting materials and post-surgery CT scan in other centers (n = 8). PRIMARY OUTCOMES: the ratio between two regions of interests (ROI) (graft to otic capsule). SECONDARY OUTCOMES: resorption of mastoid grafts and assessment of clinical tolerance. RESULTS: Included 21 patients (mean age: 29 ± 21 years; 5 females, 16 males). Significantly higher osseointegration for BHA vs. BG (R1 p = 0.043; R2 p = 0.004); almost perfect inter-reader agreement k = 0.922). The ROI ratios for BHA and BG to that of the otic capsule were 0.57 ± 0.11 (R1) and 0.59 ± 0.14 (R2); 0.43 ± 0.11 (R1) and 0.43 ± 0.08 (R2), respectively. Density increased significantly by 399 ± 261 Hounsfield units (HU) (p = 0.008) and decreased by 464 ± 161 HU (p < 0.001) for BHA vs. BG. Resorption rates were 24.1 ± 21.0% and 66.7 ± 15.1% (p = 0.076), respectively. No significant difference in clinical tolerance was observed. CONCLUSION: Post-operative CT scan of mastoid obliteration seems reliable in assessment of biomaterial graft's mid-term feasibility and stability: BHA seems to provide a more optimal osseointegration versus BG with no significant differences in graft resorption and clinical tolerance.
