Learning Objectives: After studying this article, the participant should be able to: 1. Discuss advantages and disadvantages of the available classification systems for cleft lip deformities. 2. Discuss, in detail, the normal anatomic features of the orbicularis oris muscle and the aberrant features seen in unilateral cleft lip deformities. 3. Define the anatomic features of the unilateral clef...

In a search for genetic differences in susceptibility to cleft palate, congenic and recombinant inbred strains of mice were treated with 6-aminonicotinamide or control injections. Of six loci tested, only the chromosome segment marked by N-acetyl transferase was found to affect susceptibility to 6-aminonicotinamide-induced cleft palate. This chromosome segment is known to affect glucocorticoid-...

The aim of this study was to measure and compare the dimensions of the dental arches on three-dimensional digital study models in children with and without cleft lip and palate before the primary surgery. The sample consisted of 223 digital models of children aged 3-9 months, divided into 5 groups: without craniofacial deformities, unilateral and bilateral incomplete cleft lip and alveolus, uni...

OBJECTIVE To review recent data on the aetiology of cleft lip and palate. DATA SOURCES MEDLINE literature search (1986-2003). STUDY SELECTION Literature and data on aetiology of cleft lip and palate using the following key words: 'cleft lip', 'cleft palate', 'aetiology', and 'genetics'. DATA EXTRACTION Relevant information and data were reviewed by the authors. DATA SYNTHESIS Cleft lip ...

Basal encephalocele is a rare craniofacial anomaly. In the present paper we report a 10-year-old boy presented with cleft palate, congenital nystagmus, and hypertelorism. During preoperative evaluation for cleft palate repair, a pulsatile mass was detected in the pharynx. Magnetic resonance imaging showed sphenoethmoidal type of basal encephalocele and agenesis of corpus callosum. Neurosurgical...

OBJECTIVES Children with cleft lip and palate universally present with otitis media with effusion. This prevalence has not been systematically studied. The purpose of the present study was to examine and compare the prevalence of otitis media with effusion, hearing sensitivity, and audiometry method utilised for assessment in children with and without clefts. METHODS Two groups of children (c...

RATIONALE Intracellular Ca(2+) concentration ([Ca(2+)]i) is regulated and signals differently in various subcellular microdomains, which greatly enhances its second messenger versatility. In the heart, sarcoplasmic reticulum Ca(2+) release and signaling are controlled by local [Ca(2+)]i in the junctional cleft ([Ca(2+)]Cleft), the small space between sarcolemma and junctional sarcoplasmic retic...

Mesenchymal stem cells (MSCs) isolated from dental tissues have also been studied extensively recently due to their relatively easy availability. The researchers working on improving a method for regenerating alveolar bone in patients with cleft lip and palate utilizing mesenchymal human marrow (hBMSCs). A systematic literature review 2010 2022 was performed using PubMed, Medline, ScienceDirect...

INTRODUCTION Cleft lip and/or palate is the most common congenital craniofacial anomaly. Ultrasonography plays a key role in the early diagnosis of this anomaly and is completed by MRI. The purpose of this paper is to present and summarize the experience in diagnosis of cleft lip/palate by means of MRI. MATERIAL AND METHODS The material consists of 62 fetuses that required more detailed evalu...
