OBJECTIVES: Partial tooth agenesis is frequently observed in Robin sequence. Tooth anomalies are increasingly considered as an extended phenotype of the cleft palate population. The study objective was to compare the prevalence and patterns of tooth agenesis in a group of patients with non-syndromic Robin sequence (ns-RS) and a group with non-syndromic cleft palate (ns-CP). MATERIALS AND METHODS: The panoramic radiographs of 115 ns-RS and 191 ns-CP patients were assessed for agenesis of the permanent dentition (excluding third molars) and the patterns recorded using the Tooth Agenesis Code...

The avian middle ear differs from that of mammalians and contains a tympanic membrane, one ossicle (bony columella and cartilaginous extra-columella), some ligaments and one muscle. The rim of the eardrum (closing the middle ear cavity) is connected to the neurocranium and, by means of a broad ligament, to the otic process of the quadrate. Due to the limited number of components in the avian middle ear, the possibilities of attenuating the conduction of sound seem to be limited to activity of the stapedius muscle...

BACKGROUND: Craniofacial microsomia (CFM) is a congenital condition with wide phenotypic variability, including hypoplasia of the mandible and external ear. We assembled a cohort of children with facial features within the CFM spectrum and children without known craniofacial anomalies. We sought to develop a standardized approach to assess and describe the facial characteristics of the study cohort, using multiple sources of information gathered over the course of this longitudinal study and to create case subgroups with shared phenotypic features...

INTRODUCTION: Any laboratory procedure exposes the technician and the pathologists to the hazardous effects of chemicals. Conventional procedures like decalcification and histo-processing employed in laboratories are labour intense and time consuming thereby delaying the report dispatch. The present study was an attempt to employ a kitchen microwave to hasten the process and facilitate faster and accurate reporting; thus, benefitting the technician, pathologist and the patient. AIM: To compare conventional and microwave based decalci-fication, processing and staining of tooth and mandibular bone specimens using 5% nitric acid as decalcifying agent...

#12
Ahmed Gaber Hassanein, Ahmed M A Abdel Mabood
PURPOSE: During surgery for major maxillofacial fractures, orotracheal intubation can interfere with some surgical procedures and nasal intubation can be contraindicated or impossible. That is why tracheotomy is presented as a solution, although it carries a relatively high incidence of complications. In this study, the use of submandibular tracheal intubation is basically evaluated as an alternative to tracheotomy in such circumstances. MATERIALS AND METHODS: This prospective study was performed in patients undergoing surgery for major maxillofacial fractures in which oral intubation and/or nasal intubation have been unsuitable, impossible, or contraindicated...

Lynn E Copes
Extremely thick cranial vaults have been noted as a diagnostic characteristic of Homo erectus since the first fossil of the species was identified, but relatively little work has been done on elucidating its variation within extant non-human primates. Cranial vault thickness (CVT) is not a monolithic trait, and the relationship of its layers to other morphological variables is unknown. Total CVT and the thickness of the cortical and diploë layers individually, as well as the ratio between diploë and total thickness, were calculated from 258 female individuals from 47 species of non-human primate...

BACKGROUND: The usefulness of the developmental status of the third molar has been studied in assessment of the chronological age of adolescents in whom the development of the other permanent teeth is nearly complete. However, little is known about the timing and pattern of third-molar development in the Indian population. AIM: This study aimed to stage the third molar development in relation to chronological age of 5-16year old Indian children. DESIGN: In this cross-sectional observational study, the status of third molar development in relation to chronological age of 1139 Indian children aged 5-16 years was evaluated radiographically, using Orhan's modification of Demirjian's method...

The submental island flap is useful as an alternative to microvascular free tissue transfer for the reconstruction of defects after resection of oral cancer because it is simple to harvest, reliable, and is associated with good oral function and low morbidity. However, because cancer of the oral cavity carries a risk of level I nodal metastases, the oncological safety of the flap remains controversial. Between April 2012 and September 2016, we studied patients with squamous cell carcinoma of the oral cavity who underwent surgical resection with submental island flap reconstruction for viability of the flap, signs of recurrence, and complications...
