“…The definitions of ''temporary'' and ''permanent'' vary. For example, Havas et al consider a dysphonia lasting longer than 6 months to be permanent, 11 whereas Wagner and Seiler allow up to 18 months for spontaneous recovery. 12 The majority of studies regard 12 months as being a reasonable spontaneous recovery interval, 13,14 but few studies, if any, provide follow-up data for this length of time.…”

The purpose of this study was to identify patients of vocal cord paralysis and to establish an etiological diagnosis. Patients with vocal cord paralysis have been followed prospectively at a tertiary referral center. 120 patients identified with vocal cord paralysis by laryngeal endoscopy were evaluated clinically, radiologically and pathologically to make an etiological diagnosis. Those patients in whom no cause was found, a CT scan from base of skull to thorax was done before labeling them as idiopathic. Most of the patients presented in 5th (26.67 %) and 6th (21.67 %) decade. Males out numbered females in the ratio 2.3:1.0. The most common symptom of vocal cord paralysis was change in voice (98.21 %). Bilateral vocal cord palsy was found in 6.67 % patients and unilateral vocal cord palsy was found in 93.33 % patients. Among patients of unilateral vocal cord paralysis left vocal cord was paralyzed in 69.64 % and right cord in 30.36 %. Malignant (34.16 %) causes accounted for largest number of patients followed by central (15.00 %) and idiopathic causes (14.16 %). VCP has got a variable etiology which varies with the laterality of the vocal cord involvement. Malignant causes predominated in our series, occurring in 34.16 %, followed by central and idiopathic causes.

“…In the absence of an obvious cause such as surgical trauma, efforts are required to determine the cause of paralysis since the most common cause is neoplasm. Left vocal fold palsies are more common than those on the right and are much more likely to be due to malignant processes, especially from pulmonary or mediastinal diseases [13][14][15][16]20]. Extensive search for occult causes should be undertaken before diagnosing idiopathic paralysis.…”

“…Diagnosis of Xth nerve paralysis allows performance of appropriate examinations to determine the underlying cause of paralysis, especially on the skull base, to rule out jugulare foramen abnormalities. However, no distinction is reported in the literature between causes of vocal fold paralysis, either from the recurrent or the Xth nerve [13][14][15][16], and the notion of which appropriate radiologic examinations are required is not addressed.…”

Laryngeal Paralysis: Distinguishing Xth Nerve from Recurrent Nerve Paralysis Through Videoendoscopic Swallowing Study (VESS)

Distinction between unilateral recurrent laryngeal nerve paralysis and Xth nerve paralysis is a rarely addressed issue in the literature. However, it may be crucial to examine the cause of the paralysis and to perform the appropriate investigation. The videoendoscopic swallowing study has been demonstrated to be a useful tool in assessing pharyngeal function. Since in unilateral Xth nerve paralysis the pharynx is impaired on the same side as the vocal fold immobility, it may be easily detected by videoendoscopic swallowing study. The rotation of the posterolateral pharyngeal wall toward the opposite side during swallowing is a sign of impaired motor pharyngeal branches. To demonstrate the usefulness of the videoendoscopic swallowing study in distinguishing unilateral Xth nerve from isolated recurrent nerve paralysis, a series of six patients were studied prospectively. Diagnosis of Xth nerve paralysis focused the investigation toward the high neck or the skull base area. Paralysis of the Xth nerve was suspected in all cases and diagnosis was achieved in five cases by the workup performed. Videoendoscopic swallowing study is a cost-effective and easily available tool which should be performed in all cases of vocal fold paralysis.

Abstract: Early intervention for symptomatic patients was found to be rewarding and safe. Vocal fold augmentation with autologous fat was particularly successful in achieving sustained improvement of voice.
