Development of the occipitopetrosal junctions: A histological study using human fetuses

open access: yesThe Anatomical Record, Volume 309, Issue 2, Page 333-345, February 2026.
Abstract The temporal bone petrosa is connected to the occipital bone at two sites: one junction with the basilar part (medial junction) and another with the lateral part (lateral junction). Using histological specimens from 45 human fetuses (approximately 7–39 weeks of gestational age or GA), we aimed to describe possible changes in histology and ...

Prelacrimal Recess‐Pterygoid Window Approach to the Sphenoidal Lateral Recess Skull Base Defects

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, Volume 12, Issue 1, Page 66-76, February 2026.
ABSTRACT Objective The objectives of this study are: (1) to evaluate the prelacrimal recess‐pterygoid window approach (PLR‐PWA) for treating cerebrospinal fluid leaks and meningoencephaloceles (CSFLME) in the sphenoidal lateral recess (SLR). (2) To investigate the pneumatization of the SLR and its relationship with surrounding structures, including the

Nasal Branch of the Anterior Ethmoidal Artery and Cribroethmoidal Groove: New Frontal Sinus Landmarks

open access: yesThe Laryngoscope, Volume 136, Issue 1, Page 105-112, January 2026.
This study investigates the nasal branch of the anterior ethmoidal artery (NbAEA) and the cribroethmoidal groove (CrEGr) as novel and reliable anatomical landmarks for expanded endoscopic frontal sinusotomies. Through cadaveric dissections and a clinical case series, both structures were consistently identified and shown to aid safe and accurate ...

Solar Roof Cooling by Evaporation

open access: yes, 1980
Evaporation is nature's way of cooling. By spraying a light film of water in the form of a mist for thirty seconds, then turning the sprays off for five minutes while evaporation takes place, the roof temperature can be reduced from 1650o to 880o.
