Trauma‐induced schwannoma of the recurrent laryngeal nerve after thyroidectomy
Laryngoscope, 2015Co-Authors: William P. Kennedy, Amber R. Wang, Robert M Brody, Virginia A. Livolsi, Natasha MirzaAbstract:Laryngeal schwannomas are rare, benign tumors, most often arising from the superior laryngeal nerve. We describe a case of a 68-year-old female with a laryngeal schwannoma of the recurrent laryngeal nerve after traumatic injury. We postulate that trauma to the recurrent laryngeal nerve during thyroidectomy or thyroplasty incited growth of a nerve sheath tumor. This is the first reported case of a trauma-induced schwannoma of the recurrent laryngeal nerve and second case of a recurrent laryngeal nerve schwannoma. Although rare, this case demonstrates that these tumors should be considered during workup of Vocal Cord Paresis after surgery or failed thyroplasty. Laryngoscope, 126:1408-1410, 2016.

symptomatic Vocal Cord Paresis paralysis in infants operated on for esophageal atresia and or tracheo esophageal fistula
The Journal of Pediatrics, 2011Co-Authors: Francesco Morini, B D Iacobelli, Alessandro Crocoli, Sergio Bottero, Marilena Trozzi, Andrea Conforti, Pietro BagolanAbstract:Objectives To describe the prevalence and pathogenesis of symptomatic Vocal Cord Paresis/paralysis (VCP) in patients treated for esophageal atresia (EA), tracheo-esophageal fistula (TEF) or both. Study design Retrospective study of all patients treated for EA/TEF in our center (1995 to 2009). Patients with and without symptomatic VCP were compared for gestational age, birth weight, associated anomalies, referrals, long-gap EA (>3cm or 3 vertebral bodies), cervical esophagostomy, anastomotic leakage, length of ventilation, and major cardiac surgery. Prevalence or median (IQR) is reported. Results Of 174 patients, 7 (4%) had symptomatic VCP. Prevalence of referrals (5/7 versus 21/167; P = .0009), long gap (5/7 versus 41/167; P = .0146), previous cervical esophagostomy (5/7 versus 7/167; P P = .0097) was higher, and ventilation longer (8.5 days [7.0 to 15.5] versus 6.0 days (5.0 to 7.0); P = .0072) in patients with VCP. Conclusions In infants treated for EA/TEF, VCP should be ruled out in case of persistent respiratory morbidity or, when present, cautiously monitored. Surgical risk factors should be actively controlled. Further studies are needed to define the prevalence of acquired and congenital VCP in patients with EA/TEF.

A Novel Lateral Approach to the Assessment of Vocal Cord Movement by Ultrasonography
World Journal of Surgery, 2017Co-Authors: Takahiro Fukuhara, Ryohei Donishi, Eriko Matsuda, Satoshi Koyama, Kazunori Fujiwara, Hiromi TakeuchiAbstract:Background Ultrasonography is a non-invasive technique that is commonly used by endocrinologists and endocrine surgeons to examine the thyroid region and could be useful for the assessment of Vocal Cord movement by these specialists. However, previous studies reported a low rate of successful visualization of Vocal Cord movement by ultrasonography. To address this issue, we devised a novel ultrasonographic procedure for assessing Vocal Cord movement indirectly by observing the arytenoid movement from a lateral view. Methods Subjects were 188 individuals, including 23 patients with Vocal Cord paralysis and 13 with Vocal Cord Paresis. We performed ultrasonographic assessment of Vocal Cord movement using two different procedures: the conventional middle transverse procedure and the novel lateral vertical procedure. Results The rate of visualization of Vocal Cords with the middle transverse procedure was 70.2% and that of the arytenoid cartilage with the lateral vertical procedure was 98.4%. The lateral vertical procedure enabled visualization of all patients with Vocal Cord Paresis/paralysis and detected all 23 patients with Vocal paralysis; only one of 13 patients with Vocal Cord Paresis was positively identified. The conventional procedure enabled visualization of 21 of 36 patients with Vocal Cord Paresis/paralysis with high accuracy. There was no false-positive case in either procedure. Conclusion The proposed lateral vertical procedure improved the rate of visualization of Vocal Cord movement by ultrasonography, suggesting that it is a useful technique to screen for Vocal Cord paralysis by ultrasonography.
