Angiofibroma of the lacrimal sac: A rare case report

Indian Journal of Ophthalmology. Case Reports
Angiofibroma of the lacrimal sac is an extremely rare condition, and very few studies have mentioned about this entity in the literature. Here, we report an unusual case of lacrimal sac angiofibroma in a young male patient who initially presented with ...

Treatment outcomes after definitive radio(chemo)therapy for 17 lacrimal sac squamous cell carcinoma.

British Journal of Radiology, 2020
OBJECTIVES Tumors of the lacrimal sac are rare and life-threatening. Because of their rarity, no extensiveclinical data on their management and prognosis exist.

Lagomorph cranial biomechanics and the functional significance of the unique fenestrated rostrum of leporids

The Anatomical Record, EarlyView.
Abstract The crania of leporid lagomorphs are uniquely fenestrated, including the posterior cranial bones and the lateral portion of the maxilla. The functional significance of the highly fenestrated rostrum has received considerably little attention, despite being absent in other mammalian herbivores with a long rostrum.

Comparison of Clinical Features and Treatment Outcome in Benign and Malignant Lacrimal Sac Tumors

BioMed Research International, 2020
Purpose To compare the clinical characteristics and treatment outcome between benign and malignant lacrimal sac tumors. Methods We retrospectively reviewed the medical records of all patients with pathologically confirmed lacrimal sac lesions from 1995 ...

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

The Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs

The Anatomical Record, EarlyView.
Abstract Brachycephaly in domestic rabbits is increasingly perceived by welfare organizations as associated with significant health complications, particularly oral pathologies. Despite this perception, comparative anatomical research into rabbit brachycephaly is limited compared to that of dogs and cats, compelling an in‐depth examination of its ...

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

The Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

The Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

The Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

Evaluation of intraoperative mitomycin C in surgical management of adult lacrimal sac mucocele

Delta Journal of Ophthalmology, 2018
Purpose The purpose of this study was to evaluate the effectiveness of intraoperative mitomycin C (MMC) with canaliculodacryocystorhinostomy (DCR) and bicanalicular silicone intubation for the management of adult lacrimal sac mucocele.
