8 Possible Causes for Absent or Hypoplastic Paranasal Sinuses

  • Fucosidosis

    Abstract 1. Two different families with a different type of fucosidase deficiency are described. 2. In the first family the activity of alpha-L-fucosidase in leucocytes of two patients with fucosidosis type I was about 4 to 8% of the normal value. The activity of alpha-L-fucosidase in the leucocytes of the father[…][ncbi.nlm.nih.gov]

  • Autosomal Dominant Prognathism

    Chest X-ray shows cone shaped thorax with narrow upper thoracic diameter, absent or hypoplastic clavicles and scapulae.[ 9 ] Pseudoarthrosis can be considered as differential[amhsr.org] […] frontal and mastoid sinuses, impacted supernumerary teeth.[amhsr.org] The cranial abnormalities include wide-open sutures, patent fontanels, presence of wormian bones and delayed ossification of skull, decreased pneumatization of paranasal,[amhsr.org]

  • Mandibulofacial Dysostosis

    paranasal sinuses ocular downward slanting palpebral fissures, due to lack of support from zygoma absent eyelids of the lower inner third of the eye notched iris notched[radiopaedia.org] […] aplasia of the external auditory meatus conductive hearing defects are present nasal obliteration of the nasofrontal angle with narrow nares hypoplasia of the alar cartilages hypoplastic[radiopaedia.org] […] curvature of the horizontal ramus of the mandible is pathognomonic may be associated with cleft palate and absence of parotid glands zygomatic arch: malformed, underdeveloped or absent[radiopaedia.org]

  • Atrophic Rhinitis

    Plain xrays show lateral bowing of nasal walls, thin or absent turbinates and hypoplastic maxillary sinuses. CT scan findings: 1.[drtbalu.co.in] Mucoperiosteal thickening of paranasal sinuses 2. Loss of definition of osteomeatal complex due to resorption of ethmoidal bulla and uncinate process 3.[drtbalu.co.in]

  • Cleidocranial Dysplasia

    Additionally, there may be poor or absent pneumatisation of paranasal, frontal and mastoid, sphenoid sinuses [9].[jocr.co.in] Facial features include depressed nasal bridge, hypertelorism with possible exophthalmos, hypoplastic mid-facial region and relatively prognathic mandible.[jocr.co.in]

  • Dauwerse-Peters Syndrome

    paranasal sinuses ocular downward slanting palpebral fissures, due to lack of support from zygoma absent eyelids of the lower inner third of the eye notched iris notched[radiopaedia.org] […] aplasia of the external auditory meatus conductive hearing defects are present nasal obliteration of the nasofrontal angle with narrow nares hypoplasia of the alar cartilages hypoplastic[radiopaedia.org] […] curvature of the horizontal ramus of the mandible is pathognomonic may be associated with cleft palate and absence of parotid glands zygomatic arch: malformed, underdeveloped or absent[radiopaedia.org]

  • Autosomal Dominant Osteosclerosis Type Worth

  • Mandibuloacral Dysostosis

    Additionally, there may be poor or absent pneumatisation of paranasal, frontal and mastoid, sphenoid sinuses [9].[jocr.co.in] Facial features include depressed nasal bridge, hypertelorism with possible exophthalmos, hypoplastic mid-facial region and relatively prognathic mandible.[jocr.co.in]
