Summary

Cervical osteophytes can alter swallowing function, leading to either compensatory increases or impairments in pharyngeal pressure and clearance. These changes may contribute to globus sensation.

Area of Science:

  • Otolaryngology
  • Gastroenterology
  • Neurology

Background:

  • Cervical osteophytes, bony outgrowths on the cervical spine, can potentially affect adjacent structures.
  • Swallowing difficulties (dysphagia) are a common concern, and their underlying mechanisms require thorough investigation.

Purpose of the Study:

  • To investigate the impact of cervical osteophytes on swallowing function.
  • To analyze changes in pharyngeal clearance and maximal swallowing pressure in patients with cervical osteophytes.

Main Methods:

  • Utilized double contrast pharyngography and manometric examinations to assess swallowing function in ten patients.
  • Classified pharyngeal clearance according to Shuzaki's classification (Type B and Type A + A').

Main Results:

Related Experiment Videos

  • Patients with Type B pharyngeal clearance showed increased maximal swallowing pressure on the oral side ipsilateral to osteophytes.
  • Patients with Type A + A' clearance exhibited decreased maximal swallowing pressure and abnormal waveforms.
  • No clear correlation was found between swallowing changes and the specific site of osteophytes.

Conclusions:

  • Cervical osteophytes can lead to compensatory increases or impairments in pharyngeal constriction and clearance.
  • Altered swallowing function due to cervical osteophytes may be linked to the development of globus sensation.
