Summary

Sudden deafness is not linked to static cranio-cervical junction changes. However, reduced upper cervical spine mobility, including hypermobile and hypomobile atlas joints, correlates with sudden deafness.

Area of Science:

  • Neurology
  • Orthopedics
  • Otolaryngology

Background:

  • Sudden deafness (SD) is an idiopathic condition often affecting one ear.
  • The cranio-cervical junction (CCJ) plays a crucial role in head and neck movement.
  • Potential links between CCJ morphology and neurological conditions are increasingly explored.

Purpose of the Study:

  • To investigate correlations between static morphological CCJ alterations and sudden deafness.
  • To assess the functional mobility of the upper cervical spine in patients with sudden deafness.

Main Methods:

  • Radiological assessment of CCJ morphology (basilar impression, ponticulus posterior, atlas assimilation, etc.).
  • Comparison of CCJ morphology between patients with sudden deafness and a healthy population.

  • Evaluation of upper cervical spine mobility, including atlanto-occipital and atlanto-dental joints, using standard deviation analysis.

    • Main Results:

    • No significant differences in static CCJ morphology were found between patients with sudden deafness and healthy individuals.
    • A statistically significant reduction in upper cervical spine mobility was observed in patients with sudden deafness.
    • High standard deviations in atlanto-occipital and atlanto-dental joints suggested both hypermobile and hypomobile atlas joints in affected patients.

    Conclusions:

    • Static morphological CCJ changes are not correlated with sudden deafness.
    • Functional pathology, characterized by altered mobility in the upper cervical spine (hypermobility and hypomobility), is significantly correlated with sudden deafness.
    • Further research into the functional biomechanics of the CCJ may offer insights into the pathophysiology of sudden deafness.
