Growing sabers: Mandibular shape and biomechanical performance trajectories during the ontogeny of Smilodon fatalis

open access: yesThe Anatomical Record, EarlyView.
Abstract The evolution of organisms can be studied through the lens of developmental systems, as the timing of development of morphological features is an important aspect to consider when studying a phenotype. Such data can be challenging to obtain in fossil amniotes owing to the scarcity of their fossil record. However, the numerous remains of Rancho

Mastoid osteoma: a case report [PDF]

open access: yes, 2016
Mastoid osteoma is a rare benign neoplasm of mesenchymal origin. Osteomas of the temporal bone are infrequent, and these mastoid osteomas are a definite rare occurrence. These tumours can present with cosmetic deformity and sometimes with pain.

Myological and osteological approaches to gape and bite force reconstruction in Smilodon fatalis

open access: yesThe Anatomical Record, EarlyView.
Abstract Masticatory gape and bite force are important behavioral and ecological variables. While much has been written about the highly derived masticatory anatomy of Smilodon fatalis, there remains a great deal of debate about their masticatory behaviors.

Complex functional and epithetic rehabilitation after ablation of recurrent retroauricular basal cell carcinoma – a case study

open access: yesGMS Interdisciplinary Plastic and Reconstructive Surgery DGPW, 2017
The reconstruction of extended defects of the concha poses a complex challenge for plastic surgeons. In cases of subtotal ablation, an rn method designed especially for elderly oncological patients consists of epithetic rehabilitation. However, inserting

Day-case management of chronic suppurative otitis media with cholesteatoma with canal wall down technique surgery: long-term follow-up [PDF]

open access: yes, 2017
The overall number of day-case otologic surgery cases is increasing; however, there is limited experience about performing canal wall down tympanoplasty in patients with chronic suppurative otitis media with cholesteatoma in this setting.

Exposed weapons: A revised reconstruction of the facial anatomy and life appearance of the saber‐toothed cat Megantereon (Felidae, Machairodontinae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Megantereon was a widespread saber‐toothed felid from the Pliocene and Pleistocene of the Old World and North America, but its rarity in the fossil record makes it complicated to restore its life appearance. Lack of complete specimens makes it necessary to combine information from fossils of different individuals to reconstruct their facial ...

Deep subcutaneous cervical emphysema related to mastoid fracture in an adolescent patient ‐ case report

open access: yesClinical Case Reports, 2022
A fracture of the mastoid bone should be considered in the work‐up of a head and neck traumatic injury. A well‐pneumatized mastoid can absorb forceful impacts, protecting middle and inner ear structures.

Segmentation of cortical bone, trabecular bone, and medullary pores from micro‐CT images using 2D and 3D deep learning models

open access: yesThe Anatomical Record, EarlyView.
Abstract Computed tomography (CT) enables rapid imaging of large‐scale studies of bone, but those datasets typically require manual segmentation, which is time‐consuming and prone to error. Convolutional neural networks (CNNs) offer an automated solution, achieving superior performance on image data.
