Globus sensation after laser-assisted uvulopalatoplasty.

PURPOSE

To determine the cause of globus sensation following laser-assisted uvulopalatoplasty (LAUP).

MATERIALS AND METHODS

Sixty consecutive LAUP patients were questioned regarding globus sensation. Palate sensation on globus patients was mapped and compared with asymptomatic LAUP control patients. Symptomatic patients were tested again 2 months later.

RESULTS

There was a 25% incidence of globus with 8% rated severe and 16% rated mild. The globus sensation corresponds to an insensate area of palate (P < .01). Resolution of the symptoms coincides with reemergence of sensation on the palate.

CONCLUSION

Sensory dennervation of the central palate is a likely source of post-LAUP globus sensation. As sensation returns, symptoms abate. Palate surgery should be designed with this in mind. It is possible that undiagnosed globus patients may have areas of anesthetic pharynx.
