Advance on endoscopic skull base surgery
Endoscopic skull base surgery started from 1990s, and has undergone fast development in the past 20 years. It has involved various skull base regions from the anterior skull base to the craniovertebral junction (CVJ) and jugular foramen, including intra-

A Baseline Approach for AutoImplant: the MICCAI 2020 Cranial Implant Design Challenge [PDF]
In this study, we present a baseline approach for AutoImplant (https://autoimplant.grand-challenge.org/) - the cranial implant design challenge, which, as suggested by the organizers, can be formulated as a volumetric shape learning task. In this task, the defective skull, the complete skull and the cranial implant are represented as binary voxel grids.

TUMORS OF THE NOSE AND PARANASAL SINUSES IN CHILDREN, CLINICAL OBSERVATIONS
Resume. Neoplasms of the nasal cavity and perinasal sinuses at the beginning of their development are asymptomatic or non-specific symptoms may appear that mask them as inflammatory diseases (acute and chronic rhinosinusitis).

A method for automatic forensic facial reconstruction based on dense statistics of soft tissue thickness [PDF]
In this paper, we present a method for automated estimation of a human face given a skull remain. The proposed method is based on three statistical models. A volumetric (tetrahedral) skull model encoding the variations of different skulls, a surface head model encoding the head variations, and a dense statistic of facial soft tissue thickness (FSTT ...

Chondroma of Falx: Case Report of a Rare Condition [PDF]
Chondroma is a benign tumor which mostly occurs in extremities but also sometimes in brain. Most intracranial chondromas arise from skull base, but chondroma of falx origin is a rare circumstance.

Chondroid chordoma of the parapharyngeal space: A case report and review of literature
Parapharyngeal space (PPS) tumors are a rare entity and account for less than 1% of all head and neck tumors. Although they exhibit a benign behavior, malignant neoplasms may arise from any of the structure contained in the space.

In vivo evaluation of wearable head impact sensors [PDF]
Inertial sensors are commonly used to measure human head motion. Some sensors have been validated with dummy or cadaver experiments, but methods to evaluate sensors in vivo are lacking. Here we present an in vivo method using high speed video to evaluate teeth-mounted (mouthguard), soft tissue-mounted (skin patch), and headgear-mounted (skull cap ...

Mathematical models for order of mutation problem in myeloproliferative neoplasm: non-additivity and non-commutativity [PDF]
In some patients of myeloproliferative neoplasm, two genetic mutations can be found: JAK2 V617F and TET2. When one mutation is present or not, the other mutation has different effects on regulating gene expressions. Besides, when both mutations are present, the order of occurrence might make a difference.

Automated placement of stereotactic injections using a laser scan of the skull [PDF]
Stereotactic targeting is a commonly used technique for performing injections in the brains of mice and other animals. The most common method for targeting stereoscopic injections uses the skull indentations bregma and lambda as reference points and is limited in its precision by factors such as skull curvature and individual variation, as well as an ...
