Abstract:
OBJECTIVES:To analyze the clinical characteristics of paroxysmal laryngospasm in adult.
METHODS:A retrospective analysis was performed on 149 patients with paroxysmal laryngospasm in adult. All patients underwent the strobolaryngoscopy, completed the reflux symptom index (RSI) or the reflux finding score (RFS). Partial patients underwent an ambulatory 24-hour pH measurement.
RESULTS:Laryngospasm was diagnosed in 76 females and 73 males. The average age was 55.4±11.4. The episode time of 149 (98%) patients last from several seconds tominutes, and 139 (93.3%) episodes could have a spontaneous remission. 84 (56.4%) episodes occurred only in the daytime, 28 (18.8%) only in the nighttime. There were 45.6% over weight/obesity patients, including 40 males and 28 females. The smokers were 28.9% (43/149) including 40 males and 3 females, and the drinkers were 29.5% (44/149) with 39 males and 5 females. 76 (51.0%) patients had no induced factor, while some caused by irritable cough/bucking (53,35.6%), cold (15, 10.1%), excitant food/smell (10, 6.7%), or regurgitation (6.5, 4.0%). Strobolaryngoscopy revealed laryngopharyngeal lesions in 46.3% (69/149) patients, including the glottic lesions with 40 (26.8%), unilateral vocal fold paralysis (21, 14.1%) and supraglottic lesions (8,5.4%). RSI/RFS showed 74.5% (111/149) patients had laryngopharyngeal reflux. Two patients treated with dietary and lifestyle modifications get improved, and 15/16 of the patients responded to antireflux treatment.
CONCLUSIONS:Episode of paroxysmal laryngospasm occurs more in the daytime, and could have a spontaneous resolution. Paroxysmal laryngospasm is much easier to occur in the male who are overweight or obesity, or with a long-term history of smoking or drinking. Almost half of the patients have an induced factor; partial may have laryngopharyngeal lesions simultaneously. Paroxysmal laryngopharyngeal reflux may be closely related to laryngospasm.
