The post-laryngectomy state is characterized by several alterations in lung function. A reliable estimation of lung function can be very useful in laryngectomees to prevent postoperative complications and to evaluate the results of the treatment.
Characterize the presence of respiratory functional disorders and the functional pattern of laryngectomees through the use of an extratracheal device.
This transversal study included 50 patients submitted to total laryngectomy at least 6 months prior to this investigation, as the treatment of choice for laryngeal cancer.
56% percent of the participants had altered breathing pattern, distributed as follows: 14 with obstructive pattern with no air trapping, 11 with obstructive pattern with air trapping and only 3 with restrictive pattern. On average, the diffusion decreased (74.3%) and airway resistance increased (121.7%) when compared to the expected average values for the Brazilian individuals.
Most patients submitted to total laryngectomy present altered lung function, usually the obstructive type, frequently associated to a history of smoking.
喉切除术后的肺部功能会发生多种变化。对于喉切除术患者来说，准确评估肺部功能非常有用，有助于预防术后并发症并评估治疗效果。
通过使用气管外设备，对喉切除术患者的呼吸功能障碍及功能模式进行特征描述。
本横断面研究共纳入 50 例至少在研究前 6 个月接受全喉切除术的患者，该术式是喉癌的首选治疗方法。
56%的参与者存在呼吸模式异常，分布如下：14 例为无空气滞留的阻塞性模式，11 例为有空气滞留的阻塞性模式，仅 3 例为限制性模式。与巴西个体的预期平均值相比，平均弥散功能下降（74.3%），气道阻力增加（121.7%）。
大多数接受全喉切除术的患者存在肺部功能异常，通常为阻塞性类型，常伴有吸烟史。
