“…Hosako-Naito et al [13] considered that mechanical trauma generated by the mucosal wave of the vocal fold could contribute to the formation of bamboo nodes. Li et al [14] proposed a mixed theory that combined mechanical micro-trauma and a local autoimmune reaction. The reason why the bamboo nodes are reported only in women is not clearly understood, but it is certainly linked to the general high prevalence of vocal fold nodules in women compared to men due to a smaller and thinner vocal fold and higher frequencies oscillation.…”

“…The reason why the bamboo nodes are reported only in women is not clearly understood, but it is certainly linked to the general high prevalence of vocal fold nodules in women compared to men due to a smaller and thinner vocal fold and higher frequencies oscillation. Although histopathology showed fibrinoid necrosis surrounded by histiocytes in the study by Li et al [14], it represents a confirmation of the diagnosis and is not essential as the diagnosis is first clinical.…”

Objective: Bamboo nodes are vocal fold lesions, mostly associated with autoimmune diseases. Patients and Methods: This is a retrospective clinical study including 10 patients with bamboo nodes. Data were collected regarding associated autoimmune disorder and type of treatment. A systematic review of the literature was conducted. Results: All patients were women, with hoarseness as the most frequent symptom. There was in most cases an associated autoimmune disease: 3 patients with systemic lupus erythematosus; 3 with rheumatoid arthritis; 1 with Sjögren syndrome; 1 with Hashimoto disease; and 1 with mixed connective tissue disease. Four patients were treated with speech therapy, 3 with oral steroids, 1 with speech therapy and oral steroids combined, 1 with oral steroids and laryngeal steroid injections, and 1 had oral steroids, surgery, and speech therapy. Speech therapy was the first-line treatment. Conclusion: Bamboo nodes should be looked for in every patient with a diagnosis of autoimmune disease complaining of dysphonia.

“…If this is not done, recurrence of bamboo nodules in the same site or other sites of the vocal folds is prone to occur. 17 However, Li et al 16 also advocated surgical resection on the premise that it may decrease the secondary inflammatory changes induced by the deposition of immune complexes. the absence of clear lesion boundaries also raises the possibility that the chronic inflammatory process might be spread throughout the whole vocal fold but is more evident in some portions and thus could appear as the transverse band stripe or bamboo nodules.…”

“…Two-dimensional vocal fold shapes were considered in the model, and vocal fold movement in the anterior-posterior plane was ignored. Many other two-dimensional models have been reported for use in phonation analysis [4][5][6][7][8]; however, these may be inadequate to deal with voice disorders caused by mass lesions localized in the anterior-posterior plane such as vocal nodules and polyps [9,10]. Some vocal fold models considering a three-dimensional structure have also been developed with analysis of fluid-induced selfexcited oscillation [11][12][13][14].…”

The geometric and biomechanical properties of the larynx strongly influence voice quality and efficiency. A physical understanding of phonation natures in pathological conditions is important for predictions of how voice disorders can be treated using therapy and rehabilitation. Here, we present a continuum-based numerical model of phonation that considers complex fluid-structure interactions occurring in the airway. This model considers a three-dimensional geometry of vocal folds, muscle contractions, and viscoelastic properties to provide a realistic framework of phonation. The vocal fold motion is coupled to an unsteady compressible respiratory flow, allowing numerical simulations of normal and diseased phonations to derive clear relationships between actual laryngeal structures and model parameters such as muscle activity. As a pilot analysis of diseased phonation, we model vocal nodules, the mass lesions that can appear bilaterally on both sides of the vocal folds. Comparison of simulations with and without the nodules demonstrates how the lesions affect vocal fold motion, consequently restricting voice quality. Furthermore, we found that the minimum lung pressure required for voice production increases as nodules move closer to the center of the vocal fold. Thus, simulations using the developed model may provide essential insight into complex phonation phenomena and further elucidate the etiologic mechanisms of voice disorders.
