Adenotonsillectomy is one of the most frequently performed surgical procedures in children. The adenoids, being located in the nasopharynx, form a major part of the vocal tract, which extends from the lips to the glottis. They have the propensity to change the shape of the vocal tract by mere hypertrophy of thelymphoid tissue. Changes in the architecture of the vocal tract occur due to removal of these lymphoid tissues during surgery and these changes are assumed to cause changes in voice in the particular individuals.[4] Examination of the changes after adenoidectomy have revealed nasalancescores get altered after surgery.

The mean age of children who underwent adenoidectomy alone in our study was 6.2 years. Their study also concluded, that even after surgery, some amount of hyponasality persisted when the study children were compared to normal …show more content…
47% of the patients in their study developed relief from the preoperative hyponasality, following surgery, almost reaching normal nasality. There was persistence of hyponasality in some patents due to nasal mucosal edema caused by allergic rhinitis and one patient who developed a hypernasal voice following the removal of the lymphoid tissues from the pharynx which eventually resolved over time to become normal nasality. Hence other associated causes for hyponasality such as allergy or a deviated nasal septum must be kept in mind when considering causes for persistence of the hyponasal voice following adenoidectomy. There are, however, studies which report complete resolution of the feature of nasalance following surgery.
The prospective study by Andreassenet al.[9] Consistent patterns of change in vocal resonance and nasalization fallowing adenoidectomy were identified. Clinical implications of these preliminary findings suggest that the maximum increase after adenoidectomy occurs at about one month and referral to speech- language pathologist should be considered if the hypernasality persists beyond three
