Effects of medialization laryngoplasty on airway resistance: A pilot study

Abstract

At physiologic airflow rates in a cadaveric model, medialization laryngoplasty implants of 11 mm or less seem to have no obvious effect on airway resistance.

Impact of unilateral vocal fold mobility impairment on laryngopulmonary physiology

“…Assessment of laryngeal abductor function may prove useful in serial monitoring of UVFMI and in assessing the impact of vocal fold medialisation or injection on airflow. There have been mixed reports in respect of the impact of UVFMI on the airway with some studies reporting a deterioration and others reporting no significant impact . Likewise, the results of comparing laryngeal medialisation with reinnervation or injection have not been conclusive.…”

“…There have been mixed reports in respect of the impact of UVFMI on the airway with some studies reporting a deterioration and others reporting no significant impact. 7,[16][17][18][19] Likewise, the results of comparing laryngeal medialisation with reinnervation 20 or injection have not been conclusive. UVFMI has an approximate population incidence of 5.1 per 100 000 adults and constitutes a sizeable portion of a laryngologist's workload.…”

Changes in respiratory function after thyroplastic surgery

“…O'Grady et al also used excised human larynges to assess the effect of silicon blocks of varying thickness in augmenting the immobile vocal fold upon airway resistance [18]. They reported a non-linear increase in airway resistance as the stent thickness increased from 5 mm to 20 mm.…”

Concomitant type I thyroplasty and thoracic operations for lung cancer: Preventing respiratory complications associated with vagus or recurrent laryngeal nerve injury

“…Currently, for numerous teams, laryngeal framework operations for vocal fold medialization, such as type I thyroplasty, are considered better techniques than intrafold injection for laryngeal rehabilitation. [7][8][9] T he surgical treatment of lung carcinoma most often consists of tumor resection associated with mediastinal lymph node dissection. Because of their anatomic location, the left vagus nerve (VN) and recurrent laryngeal nerve (RLN) are exposed to cancer invasion and to surgical injury.…”
