The cycle of alternating distribution of nasal airflow was investigated in 15 adults. Information about cyclic activity was obtained from the areas of condensation formed by nasal expiration on the surface of a Gertner-Podoshin plate. Consecutive measurements of these areas were made at 15 minute intervals during a 6-8 h period. Five control subjects demonstrated a nasal cyclic activity which was absent in 5 patients 1-3 years post laryngectomy. Two patients with preoperative cycles showed none 3 weeks after laryngectomy. Three patients with temporary surgical diversion of supraglottic airflow showed cessation of the cycle, which resumed after restoration of the natural airway; one of these patients had undergone hemilaryngectomy with section of both superior laryngeal nerves. These results demonstrate cessation of the cycle following chronic absence of supraglottic airflow, temporary cessation during acute absence, and independence of the cycle from superior laryngeal innervation.
对15名成年人的鼻气流交替分布周期进行了研究。关于周期性活动的信息是从格特纳 - 波多申板表面上由鼻呼气形成的冷凝区域获得的。在6 - 8小时期间，每隔15分钟对这些区域进行连续测量。5名对照受试者表现出鼻周期活动，而5名喉切除术后1 - 3年的患者则没有这种活动。2名术前有周期的患者在喉切除术后3周没有出现周期。3名声门上气流暂时通过手术改道的患者显示周期停止，在自然气道恢复后又重新开始；其中1名患者接受了半喉切除术，双侧喉上神经均被切断。这些结果表明，声门上气流长期缺失后周期停止，急性缺失时暂时停止，且该周期独立于喉上神经支配。
