Background and Objectives : Conservation laryngeal surgery is designed to remove the
cancer mass completely while preserving the physiologic functions of the larynx.
Recently, the supracricoid partial laryngectomy(SCPL) has broadened the spectrum of
reliable techniques available to conservation laryngeal surgeons. Much research has been
devoted to the surgical technique and oncological results of SCPL, but only a few
significant objective reports of the phonatory results are available presently. This study
was designed to analyze the phonatory results achieved after SCPL for laryngeal cancer.
Materials and Methods : Selected characteristics of the speech and voice were
compared in 25 patients who had undergone SCPL and 10 normal adult laryngeal(NAL)
speakers. Durational and frequency features were analyzed with the CSL and the
MDVP.
Results : SCPL speech proved comparable to NAL speech at the average fundamental
frequency. SCPL spech and voice were statistically less efficient than NAL speech in
jitter, shimmer, harmonics-to-noise ratio, mean airflow rate, maximal phonation time,
and subglottic preassure(p<0.01). The completion of an arytenoid cartilage resection
and/or anterior cricoid cartilage removal did not statistically modify the durational and
frequency features of SCPL speakers(p<0.01).
Conclusion : The voice parameters of SCPL speakers were different from those of the
NAL speakers, but patients were thought to be allowed social interaction.
