TLDR
This review aims to provide an update on the current understandings of surgically-induced injury to the laryngeal nerves to clarify any differences between the transient and permanent injury of the RLN.Abstract:
Loss of function in the recurrent laryngeal nerve (RLN) during thyroid/parathyroid surgery, despite a macroscopically intact nerve, is a challenge which highlights the sensitivity and complexity of laryngeal innervation. Furthermore, the uncertain prognosis stresses a lack of capability to diagnose the reason behind the impaired function. There is a great deal of literature considering risk factors, surgical technique and mechanisms outside the nerve affecting the incidence of RLN paresis during surgery. To be able to prognosticate recovery in cases of laryngeal dysfunction and voice changes after thyroid surgery, the surgeon would first need to define the presence, location, and type of laryngeal nerve injury. There is little data describing the events within the nerve and the neurobiological reasons for the impaired function related to potential recovery and prognosis. In addition, very little data has been presented in order to clarify any differences between the transient and permanent injury of the RLN. This review aims, from an anatomical and neurobiological perspective, to provide an update on the current understandings of surgically-induced injury to the laryngeal nerves.read more

The Physiologic Impact of Unilateral Recurrent Laryngeal Nerve (RLN) Lesion on Infant Oropharyngeal and Esophageal Performance
Francois D. H. Gould,Andrew R. Lammers,Jocelyn Ohlemacher,Ashley Ballester,Luke Fraley,Andrew Gross,Rebecca Z. German +6 more
TL;DR: The results indicate that RLN lesion leads to increased frequency of aspiration, and increased esophageal dysfunction, with significant variation in these basic patterns at all levels, and suggests that neurological variation underlies this pattern.

Timing of Nimodipine Therapy for the Treatment of Vocal Fold Paralysis
TL;DR: To retrospectively determine optimal timing for initiation of nimodipine within a cohort of patients with acute vocal fold paralysis, data are presented on patients diagnosed with VFP in the 1990s.

Application of transoral continuous intraoperative neuromonitoring in natural orifice transluminal endoscopic surgery for thyroid disease: a preliminary study.
TL;DR: Cont-IONM is feasible and safe to use during transoral endoscopic thyroidectomies and may assist in the early detection of adverse EMG changes, thereby preventing paralysis of the RLNs.

Routine laryngoscopy in thyroid surgery: A valuable adjunct
TL;DR: The authors argue that if the patient’s preoperative voice is normal, the vocal cords are generally normal, and that in patients with suspected malignancies, voice changes, or reoperative thyroid operations, laryngoscopy is essential.

Neuronal survival and glial reactions after recurrent laryngeal nerve resection in the rat.
TL;DR: The aim of the present study was to investigate retrograde reactions, neuronal survival, and glial reactions in the nucleus ambiguus after a distal resection of the RLN to evaluate the potential need for neuroprotective substances.

Strobokymographic and videostroboscopic analysis of vocal fold motion in unilateral superior laryngeal nerve paralysis.
TL;DR: Kymograms of both human and canine subjects with SLNp demonstrated an undulating motion of the horizontally shifting glottic space as the medial edges of the vocal folds chased each other 90° out of phase, which appears to be unique to SLNP.

Motor neurons of the laryngeal nerves.
TL;DR: The rostral distribution of the recurrent laryngeal nerve motor neurons is defined and it is suggested that this roStral group is a component of the neuroanatomical substrate that is involved in the co‐activation of the larynGEal abductors controlling the lARYgeal aperture.
