Osteotomy Techniques in Endoscopic Dacryocystorhinostomy: A Three‐Decade Comparative Cohort Study

Laryngoscope Investigative Otolaryngology, Volume 11, Issue 4, August 2026.
ABSTRACT Objective Endoscopic dacryocystorhinostomy (DCR) is a well‐established surgical procedure used to restore lacrimal drainage in patients with nasolacrimal duct obstruction. Various instrumentation techniques have been used for lacrimal bone osteotomy; however, their comparative effectiveness remains debated.

Comparative endocranial anatomy in the crocodylians Leidyosuchus canadensis and Stangerochampsa mccabei from the upper Cretaceous of Alberta, Canada

Journal of Anatomy, Volume 249, Issue 2, Page 264-291, August 2026.
Leidyosuchus canadensis and Stangerochampsa mccabei share endocranial features such as posterior projection of a neurovascular canal in the maxilla and a paratympanic sinus system most similar to those of small‐bodied and young extant crocodylians, suggesting that these pedomorphic features may reflect the ancestral crocodylian condition.

Micro‐CT informed cranial anatomy of the early rhynchosaur Howesia browni, with implications for rhynchosaur skull evolution

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Rhynchosaurs are unusual archosauromorph reptiles that lived between the Induan and early Norian (Early to early Late Triassic). They are characterized by their stocky build and broad skull with a beak‐like premaxilla. This rather charismatic configuration is most clearly expressed in Late Triassic hyperodapedontine rhynchosaurids.
