Surgical management of laryngeal paralysis varies depending on whether the vocal cords are in abduction, adduction or paramedian position. Various surgical techniques have been described including partial arytenoidectomy which is reported to give good surgical results that are stable over time. The objective of the study was to analyze the surgical therapeutic elements of bilateral paralysis, especially to assess partial arytenoidectomy, one of the most performed techniques. This was a descriptive retrospective study of cases of bilateral immobility admitted between January 1^st 2008 and March 31^st 2018 and treated surgically. Socio-demographic and therapeutic data were collected. The survey involved 46 patients, with an equal number of male and female (23) with 50% of male patients and 23 patients were female, or a sex ratio of 1. The average age of the patients was 56 ± 17 years ranging between 14 and 89 years. Posterior partial arytenoidectomy was the most widely performed surgical technique (26 patients or 56.5%), followed by cordopexia or lateral-fixing of a vocal cord (19.6%) and posterior cordectomy (17.4%). Patients who received a partial arytenoidectomy and cordopexia had their vocal cords either in adduction or in the paramedian position. Those who received a posterior cordectomy had their vocal cords in adduction. 18 patients (39.13%) were taken to the operating theatre in less than 6 hours, 28 (60.9%) had no post-operative complications, and 9 patients received a surgical enlargement resumption. In post-operative follow-up, 11 patients suffered pulmonary aspiration corrected after speech therapy; 26 patients (56.5%) did not. Partial arytenoidectomy remains the most performed surgical procedure in the management of closed bilateral laryngeal paralysis at the Mont-Godinne University Hospital. It allows a reliable and durable breathing function over time with less impact on the voice.
