PurposeThis study was performed to evaluate the general anatomy and morphology of the nasopalatine canal using cone-beam computed tomography (CBCT) and to determine the human anatomic variability of the nasopalatine canal in relation to age and gender.Materials and MethodsThe study included 100 subjects aged between 20 and 86 years who were divided into the following 3 groups: 1) 20-34 years old; 2) 35-49 years old; 3) ≥50 years old. The subjects were equally distributed between the genders. CBCT was performed using a standard exposure and patient positioning protocol. The data of the CBCT images were sliced in three dimensions. Image planes on the three axes (X, Y, and Z) were sequentially analyzed for the location, morphology and dimensions of the nasopalatine canal by two independent observers. The correlation of age and gender with all the variables was evaluated.ResultsThe present study did not reveal statistically significant differences in the number of openings at the nasal fossa; diameter of the nasal fossa openings; diameter of the incisive fossa; shape, curvature, and angulation of the canal as viewed in the sagittal sections; antero-posterior dimensions and length of the canal in the sagittal sections; or the level of division of the canal in the coronal plane by age. However, males and females showed significant differences in the length of the canal in the sagittal sections and level of the division of the canal in the coronal plane.ConclusionThe present study highlighted important variability observed in the anatomy and morphology of the nasopalatine canal.

Klippel-Feil syndrome (KFS) is a complex syndrome of osseous and visceral anomalies that include the classical clinical triad of short neck, limitation of head and neck movements and low posterior hairline. It may also be associated with anomalies of the genitourinary, musculoskeletal, neurologic and cardiac systems. We report a case of type III KFS with associated rib anomalies such as cervical rib, fusion and bifid ribs, scoliosis and fused crossed renal ectopia. The aim of this paper was to summarize all craniofacial anomalies that occur in association with KFS, so that clinicians would be aware of them during diagnosis and treatment planning.

Hurler syndrome is a disorder of mucopolysaccharide metabolism caused due to inherited deficiencies of lysosomal α-l-iduronidase activity. We present a case of a 15-year-old male patient presenting with clinical and laboratory characteristics of the syndrome. A rare combination of skeletal, ophthalmologic, and dental findings was observed in this patient. Mucopolysaccharides excretion spot test of urine was positive and an assay of alpha-l-iduronidase enzyme was deficient, confirming the clinical diagnosis of Hurler syndrome.
