“…The importance of glottic closure in the generation of subglottic core pressure has been mentioned. Pressman, observing the intravesical (urinary bladder) pressure during bronchoscopy with local anaesthesia, found that straining with the bronchoscope occluded raised the pressure to a significantly higher degree than with the bronchoscope open (Pressman, 1944). The ability to raise the intra-abdominal pressure during Valsalva's manoeuvre with the glottis closed and to bear down with the glottis open has been evaluated in healthy volunteers.…”

Type I thyroplasty was performed in 12 patients with unilateral paralysis of the vocal fold. Subjective as well as objective improvement in vocal performance was reported in 11 patients. Aspiration was improved in six out of eight patients. Effort closure was evaluated by the ability of the patient to voluntarily raise his intra-abdominal pressure during Valsalva's manoeuvre. A comparison of pre- and post-thyroplasty measures, showed a statistically significant improvement in the efficacy of effort glottic closure (p < 0.05), indicating a better physical performance. We had one case of wound sepsis and another case of implant extrusion.

Neurofibromas of the larynx are extremely rare, especially in the subglottic part. Most of the patients with neurofibromas suffer from neurofibromatosis type 1 (NF1, von Recklinghausen's disease), which is characterized by cafe-au-lait spots and neurofibromas of any type. We present a case of a solitary neurofibroma in the subglottic region that relapsed 4 years after the primary diagnosis. The clinical findings, histological results and therapy are discussed.
