The Nasopharyngo‐Septal Butterfly Flap: A Novel Adjunct for Reconstructing Large Skull Base Defects

open access: yesOTO Open
Objective Skull base defects can be challenging to reconstruct. The nasoseptal flap (NSF) remains the first‐line option for reconstruction. However, it can be inadequate to cover wide defects or compromised by tumor invasion or prior surgery requiring ...

Nasal Tuft Cell Markers Are Predictive of Overall Survival in Sinonasal Neuroendocrine and Sinonasal Undifferentiated Carcinomas

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Sinonasal neuroendocrine carcinoma (SNEC) and sinonasal undifferentiated carcinoma (SNUC) are rare aggressive malignancies with no established prognostic markers. Because features of POU2F3+ small cell lung carcinomas have been identified in both tumors, we evaluated immunostaining for POU2F3, a tuft cell transcription factor, and ...

Assessing the Mucosal Inflammatory Endotype of Obesity in Chronic Rhinosinusitis

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) is a heterogeneous inflammatory syndrome of the paranasal sinuses that is defined phenotypically as either with nasal polyps (CRSwNP) or without nasal polyps (CRSsNP). More recently, inflammatory markers have been used to cluster patients into putative endotypes that are presumed to have a common ...

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

open access: yesThe Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Tooth row allometry in domestic rabbits and nondomestic lagomorphs: Evidence for a decoupling of body and tooth row size changes in evolutionary time

open access: yesThe Anatomical Record, EarlyView.
Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

Ontogeny of murine bony semicircular canal form

open access: yesThe Anatomical Record, EarlyView.
Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

open access: yesThe Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Surgical Techniques and Functional Reconstruction for Complex Tenosynovial Giant Cell Tumor of Temporal Bone and Middle Skull Base

open access: yesEar, Nose & Throat Journal
Objectives: Temporal tenosynovial giant cell tumors (TGCTs) are often large and have invaded the middle skull base. It is difficult to protect the important neurovascular structures around the tumor and perform functional reconstruction on the basis of ...
