After snoring operation, he returned to the hospital at 6, 12 and 24 weeks after operation for reexamination of nasopharyngoscope, otoscope, acoustic immittance, pure tone audiometry and TMM. The patients were assessed with ETDQ-7 score, ETS-7 score and VAS score by self-administered questionnaire.
