This paper summarizes and evaluates the oral complications associated with orotracheal intubation in neonates. The palatal defect resulting from orotracheal intubation is best described as palatal grooving, rather than clefting since no oral nasal communication has been demonstrated. Palatal grooving may be caused by the inhibition of the molding tongue(More)
Three tall, phenotypic female siblings with XY gonadal dysgenesis were found to have short fourth metacarpal bones (bilateral in two and unilateral in the other). Clitoromegaly was observed in the two older siblings, without hirsutism. Bilateral streak gonads were found in all three. A gonadoblastoma was present in the left streak gonad of the youngest, and(More)
Otodental dysplasia is an ectodermal dysplasia characterized by abnormal crown morphology of the teeth and sensorineural hearing loss. It was documented in six generations of a kindred of Italian extraction. Thirty-three of the 119 examined family members were affected. Twenty-six persons had characteristic dental anomalies combined with a hearing loss. Two(More)
Peripheral auditory sensitivity is documented over a 5-year period on 4 cases with otodental dysplasia. Age of onset is noted for the proband and indicates that onset of this progressive hearing loss occurs as early as the first decade. Findings suggest that the hearing loss plateaus by the fourth decade, resulting in a severe, flat, bilaterally symmetrical(More)
The case of a 3 11/12-year-old Chinese boy with the dental abnormalities of "otodental" dysplasia is reported. Hearing was normal. Dental anomalies consisted of delayed eruption of globe-shaped molars, bulbous deciduous canines, and double pulp chambers in the molars. Radiographs taken 4 years later showed taurodontic molars, supernumerary microdontic(More)
The Morquio syndrome is characterized by a specific pattern of platyspondylia, corneal opacities, keratosulfate excretion in the urine, and dental abnormalities. Oral examinations were performed on twelve patients with the condition. The maxillary anterior teeth were widely spaced and flared. The posterior teeth were tapered and had pointed cusp tips.
