| Summary: | Introduction: Alterations in the configuration of the
nasal cavity made surgicallyvia procedures such as
turbinectomy have been assumed to cause changes in the
perceived nasal resonance of the patients post surgery which
tends to manifest changes in the overall voice perception.
These changes though perceivable are reported to be transient
in nature and eventually fall in place as the post surgical
duration increases.
The purpose of this study was to probe the changes in
nasal resonance that affect perceived voice quality following
turbinectomy in patients with hypertrophied inferior turbinates
secondary to allergic and vasomotor rhinitis, by checking
serially obtained nasalance scores.
Aim of the study: The aim of the study is to assess the
pre and postoperative nasal resonance and thereby voice
quality in patients with hypertrophied inferior turbinates
following turbinectomy.
Materials & Methods: The patients who underwent
Turbinectomy, at FMMCH, Mangalore from March 2015 to
October 2016 were included in the study. The diagnosis was
made based on patient history, clinical examination and nasal
endoscopy. The Nasalance was assessed using the Nasometer
module of VAGHMI, voice and speech system, Bangalore.The
nasalance scores were recorded before surgery and at intervals
of 1st , 3rd and 5th month post surgery.
Results: A total of 90 patients were enrolled, out of
these 60 patients successfully completed follow up visits on a
regular basis. The mean nasalance scores for nasal sounds [m]
[ma] and [mi] showed significance before surgery and at the
1st and 3rd month post-surgery. Consequently, nasalance values
returned within normal range at the 3rd month post operatively.
While the mean nasalance scores for non nasal sounds [a] [i]
and [u] returned to normal range at the 5th month post
operatively.
Conclusion: The presence of a hypertrophied inferior
turbinate and the excision of the same can alter the overall
perceived nasal resonance of an individual. Though transient,
these changes cause significant change in the nasalence scores.
A significant amount of hyponasality is perceived and recorded
in the pre operative nasalence scores while hypernasality is
perceived and recorded for a period of 3 months post surgery
which eventually diminishes and normalizes by the 5th month
post surgery. Therefore, surgeons can conveniently reassure
patients of the transient nature of the pre and post voice and
nasal alterations associated in these conditions. This
information will be highly beneficial to patients who are
professional voice users |
