Sleep-physiological correlates of brachycephaly in dogs [PDF]

Brain Structure and Function, 2023
AbstractThe shape of the cranium is one of the most notable physical changes induced in domestic dogs through selective breeding and is measured using the cephalic index (CI). High CI (a ratio of skull width to skull length > 60) is characterized by a short muzzle and flat face and is referred to as brachycephaly.

Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs [PDF]

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 ...

Correlation of brachycephaly grade with level of exophthalmos, reduced airway passages and degree of dental malalignment' in Persian cats.

PLoS ONE, 2021
For many years, there has been a trend to breed cats with an increasing degree of brachycephalic head features, which are known to have a severe impact on the animals' health and welfare.

Canine Brachycephaly: Anatomy, Pathology, Genetics and Welfare

Journal of Comparative Pathology, 2020
Brachycephalic dog breeds have experienced a marked rise in popularity in recent years. While numerous people clearly desire this phenotype in their pets, many of these dogs unfortunately experience several concomitant sequelae, including major problems with respiration and thermoregulation, as well as gastrointestinal, ophthalmological, dermatological,

Brachycephaly, Ear Anatomy, and Co—Does Size Matter? A Retrospective Study on the Influence of Size-Dependent Features Regarding Canine Otitis Externa [PDF]

Animals
This study, which involved 868 patients, focused on size-dependent features (body size, pinna formation, brachycephaly, overweight) and their associations with the occurrence of canine Otitis externa.

Helmet Treatment of Infants With Deformational Brachycephaly [PDF]

Global Pediatric Health, 2018
Deformation of the cranium in infancy represents a spectrum of deformity, ranging from severe asymmetric yet proportional distortion of the skull in plagiocephaly, to nearly symmetric yet disproportional distortion in brachycephaly.

Exceptional Changes in Skeletal Anatomy under Domestication: The Case of Brachycephaly [PDF]

Integrative Organismal Biology, 2021
Synopsis“Brachycephaly” is generally considered a phenotype in which the facial part of the head is pronouncedly shortened. While brachycephaly is characteristic for some domestic varieties and breeds (e.g., Bulldog, Persian cat, Niata cattle, Anglo-Nubian goat, Middle White pig), this phenotype can also be considered pathological.

Quantification of Bilateral Coronal Synostosis: Anterior Brachycephaly [PDF]

The Cleft Palate Craniofacial Journal, 2020
Objectives: Very few studies focus on the quantification of severity of synostotic anterior brachycephaly. Aim of this study is to implement Utrecht Cranial Shape Quantifier (UCSQ) in brachycephaly patients to objectively quantify severity for both clinical and research purposes. Design: Retrospective study.

Deformational brachycephaly: the clinical utility of the cranial index [PDF]

Journal of Neurosurgery: Pediatrics, 2020
OBJECTIVEThe incidence of deformational brachycephaly has risen since the “Back to Sleep” movement in 1992 by the American Academy of Pediatrics. Brachycephaly prevalence and understanding the dynamic nature of the pediatric skull have not been explored in relation to the cranial index (CI). The objective of the study was to determine the prevalence of

Nance-Horan Syndrome: Further Delineation of the Affected Male and the Female Carrier Phenotypes. [PDF]

Am J Med Genet A
ABSTRACT Nance‐Horan syndrome (NHS; OMIM 302350) is a rare, X‐linked syndrome characterized by bilateral congenital cataracts leading to profound vision loss, specific dental anomalies including characteristic screwdriver blade‐shaped incisors, facial anomalies, and intellectual disability.
