Uvulectomy is mainly used for surgery related to palatopharyngoplasty, tumors of the uvula, or overgrowth of the uvula. If the uvula is removed normally, it will not cause very serious harm. If too much of the uvula is removed during surgery, it may lead to the following hazards: 1, nasopharyngeal reflux, if too much is removed, it will lead to food reflux when the patient swallows and enters the nasopharynx or even the nasal cavity, which often occurs clinically, especially if the uvula is removed more than 2/3, it may induce. 2, dysarthria, if too much of the uvula is removed, the patient may have a change in voice quality when pronouncing. If the uvula is excised too much, the patient may have a change in voice quality, especially if the soft palate is also excised too much, it will be more obvious. The patient’s pharyngeal disease must be evaluated when the uvula is removed clinically, and it is not appropriate to remove too much to avoid the impact of difficult recovery.
