The surgical correction of nasal septal deviation observed in children is usually postponed until adult age presumably on the assumption of interference with facial growth. In order to elucidate this hypothesis, the entire basis of the cartilaginous nasal septum and vomer was extirpated in a group of growing domestic cats. The operation resulted in a basally unsupported septum being separated from the palatal halves by loose connective tissue. The sagittal mid-facial growth in these animals was then compared with that of sham-operated and unoperated controls. From measurements on lateral skull radiograms, taken at the start and end of the experiment, no difference in sagittal mid-facial development could be found among the three groups. The findings suggest that growth of the nasal septum/vomer, at least at its basal parts, is not involved in facial development during the period from infancy to adulthood.

Objective: Rete pegs are projections of the oral epithelium into connective tissue. Their dimensions change during pathological conditions and may correlate with wound-healing status. Non-invasive, high-frequency ultrasound (US) may be able to capture these changes and aid in early detection of histopathological changes.

Objective: To evaluate the effects of rapid maxillary expansion (RME) on mid-facial depth in early mixed dentition and to investigate the relationship between change in mid-facial depth and maxillary sinus and nasal cavity.
Methods: A total of 35 patients with mixed dentition treated with a Haas expander were included in this retrospective study. All patients underwent a cone-beam computed tomography scan before and after rapid maxillary expansion.

Objective: The goal of registering the condylar guidance is to recreate the patient's occlusion as exactly as possible on the articulator, and is therefore essential for successful prosthodontic rehabilitation. Clinical, radiographic, and pantographic methods are used to determine sagittal condylar guidance angles (SCGAs). These methods generate different angles in the same patients.

Background: Pseudohypoparathyroidism (PHP, OMIM #103580) is a very rare disease (incidence 0.3-1/100,000). Heterozygous inactivating mutations involving the maternal GNAS exons 1-13 that encodes the alpha subunit of the stimulatory G protein (Gsα) cause inactivating parathyroid hormone (PTH)/PTHrP signalling disorder type 2 (iPPSD2 or PHP type 1A), which is characterized by Albright hereditary osteodystrophy and resistance to multiple hormones that act through the Gsα signalling pathway (including PTH, thyroid-stimulating hormone, and α-melanocyte-stimulating hormone).

Objective: To compare the distance between the sphenoid and frontal bones on three-dimensional (3D) ultrasound in euploid and trisomy-21 fetuses at 16-24 weeks' gestation.
Methods: We acquired 3D volumes of the fetal profile from 80 normal and 30 trisomy-21 fetuses at 16-24 weeks' gestation. We used the multiplanar mode to obtain the mid-sagittal plane and measured the sphenofrontal distance as the shortest distance between the most anterior edge of the sphenoid bone and the lowest edge of the frontal bone.
