It is hypothesized that real time objective measurement of the subglottic pressure could contribute to the choice of the implant's size (IS) in medialization thyroplasty (MT). A prospective study was conducted with patients with glottal insufficiency. Patients had a MT using a Montgomery implant (Boston medical, Boston, USA). Peak direct subglottic pressure (PDSGP) was measured intraoperatively using a catheter inserted in the cricothyroid membrane. The implant's choice was based on the results of PDSGP measured prior and after placement of the implant and was compared to the surgeon's and patient's perception and fiber optic estimation of the glottis aperture. Six patients were included in the first part of the study. The PDSGP could be measured in all the patients without increasing the surgical time or patients' discomfort. The mean PDSGP before and after the placement of the implant was 15.2 (SD = 5) and 10.6 (SD = 4) cmH2O, respectively. In the second part of the study, five patients were included. The PDSGP varied with the size of the implant and the implant with the lowest pressure was chosen in 4/5 patients. Peroperative measurement of PDSGP is easy, feasible and might allow a more objective choice of the IS in MT. Level of evidence 2c © 2011 Springer-Verlag.
