Anatomical Variations of Recurrent Laryngeal Nerve: The Danger in Thyroid Surgery

Objectives: We report two types of anatomical variations of the recurrent laryngeal nerve in two patients. Through these two patients we wanted to highlight our surgical approach of the recurrent nerve in an unusual position and to describe the surgical implication of these almost rare variations. Case report: patient aged 28 and 58 admitted for goiter. They underwent a right lobisthmectomy. Both recurrences were approached retrograde. The anatomical variations of the nerve concerned the non-recurrent laryngeal nerve in the first patient. In the second patient there were three anatomical variations, namely an extra laryngeal bifurcation of the nerve, a pre-vascular position of the nerve and a branch connecting the vagus nerve and the recurrent nerve. No recurrence nerve injury was noted. Conclusion: The anatomical variations of the nerve are numerous. A careful dissection is a guarantee of a good prognosis.

Schwannoma originating from the recurrent laryngeal nerve in a thyroid cancer patient: A case report and review of the literature

BACKGROUND Schwannoma rarely originates from the recurrent laryngeal nerve, and there are few reports on schwannoma originating from the recurrent nerve in the mediastinum. Herein, we present an extremely rare case of schwannoma originating from the recurrent laryngeal nerve in the neck.CASE SUMMARY This is a case report of one patient diagnosed with thyroid cancer with schwannoma originating from the recurrent laryngeal nerve in the neck, which was incidentally found during a thyroidectomy, and a review of the literature.CONCLUSION Preoperative diagnostic examinations are of less use for detecting schwannoma originating from a recurrent laryngeal nerve in the neck in such small size, which may only incidentally be found during a thyroidectomy. Surgical excision with opening the capsule and shelling out the tumor is the treatment of choice. If the nerve is unable to be preserved, end-to-end recurrent laryngeal nerve anastomosis may be a simple and minimally invasive reconstruction procedure to improve phonation.

Electrophysiological neuromonitoring of the laryngeal nerves in thyroid and parathyroid surgery: A review

Recurrent laryngeal nerve(RLN) injury is one of the most common complications of thyroid surgery. Injury to the external branch of the superior laryngeal nerve is less obvious and affects the voice variably; however, it can be of great significance to professional voice users. Recent literature has led to an increase in the use of neuromonitoring as an adjunct to visual nerve identification during thyroid surgery. In our review of the literature, we discuss the application, efficacy and safety of neuromonitoring in thyroid surgery. Although intraoperative neuromonitoring(IONM) contributes to the prevention of laryngeal nerves injury, there was no significant difference in the incidence of RLN injury in thyroid surgery when IONM was used compared with visual identification alone. IONM use is recommended in high risk patients; however, there are no clear identification criteria for what constitutes "high risk". There is no clear evidence that IONM decreases the risk of laryngeal nerve injury in thyroid surgery. However, continuous IONM provides a promising tool that can prevent imminent nerve traction injury by detecting decreased amplitude combined with increased latency.

Surgical Reports of the Inferior Laryngeal Nerve and the Inferior Thyroid Artery in General Surgery and in ENT

Aim: The purpose of this study was to determine the frequency of the hurts of the inferior laryngeal nerve, according to its anatomical reports with the inferior thyroid artery during the thyroid surgery. Methodology: We realized a forward-looking and retrospective study from January, 1979 till December, 2017 in the service of surgery “B” to the University hospital of the Point G of Bamako and in the service of ENT and cervico-facial surgery of the Teaching Hospital “Mother-Child”, the Luxembourg of Bamako (Mali). All the patients operated in both services for mild goiters were retained. Cancers and other thyroid pathologies were not included. The diagnosis of mild goiter was paused by the histological examination realized on all the surgical specimens. Results: On 2109 dissections of the inferior laryngeal nerve realized during the surgical operations on the thyroid, the frequency of lesion of the inferior laryngeal nerve was 1.09% (20 cases) when it passed dorsally with regard to the inferior thyroid artery (1837 cases) and when 4.04%, it was transvascular or prevascular (272 cases). Conclusion: The prevascular route or transvascular of the inferior laryngeal nerve favors its lesion per operating.

Applied anatomy of the cervical region of the recurrent laryngeal nerve

BACKGROUND AND OBJECTIVE： To avoid recurrent laryngeal nerve （RLN） injury during thyroid surgery, it is important to identify the nerve and to follow its projection carefully to discriminate it from the inferior thyroid artery. DESIGN, TIME AND SETTING： All studies were performed at the Anatomy Division of Shaoyang Medical College from May 2003 to May 2004 with repeated measurement design. MATERIALS： Fifty embalmed adult corpses, comprising 20 females and 30 males, were obtained by donation. METHODS AND MAIN OUTCOME MEASURES： The projection, branches, and the relationship of the RLN to the inferior thyroid artery were observed. RESULTS： The RLN in all cases ascended through the tracheoesophageal groove at the isthmus superior levels of the thyroid gland. However, the RLN in 14 cases were situated inferior to the isthmus of the thyroid gland; 11 cases were to the right side and 2 cases to the left side, projected in the tracheoesophageal groove, and ascended away from the groove after 4.5-6.5 mm. The RLN typically ramified at the thyroid isthmus plane （44 cases, 44% of all cases）. The RLN branches were variable. Type 2 rami were most common in the RLN, accounting for 55%; the second most common was RLN branches with no rami. RLN braches with type 3 rami, 4 rami, and 5 rami were less common. Approximately 54% of nerves were situated behind the main branch artery. The nerves located adjacent to the arteries, and between the arterial branches, were similar; the former applied to 19 cases, accounting for 19%, whereas the latter applied to 18 cases, accounting for 18%. Left nerves behind the artery, and right nerves before the artery, were more common. There were significant differences between the left and right nerves （P 〈 0.01）. CONCLUSION： There was not a significant difference in the projection of the RLN, while a significant difference in the number of RLN branches existed. In addition, the anatomical relationship of the RLN and the inferior thyroid artery exhibited side differences.

Premature Division of the Inferior Laryngeal Nerve in Surgery and in ENT and Cervico-Facial Surgery in Mali

The purpose of this study was to study the frequency of premature division of the inferior laryngeal nerve and its consequences in thyroid surgery. Methodology: We realized a forward-looking and retrospective study from January, 1979 till December, 2017 in the service of surgery B to the University hospital of the Point G of Bamako and in the service of ENT and cervico-facial surgery of the CHU “mother-child”, the Luxembourg of Bamako (Mali). All the patients operated in both services for mild goiters were included. Cancers and other thyroid pathologies were not included. The diagnosis of mild goiter was paused by the histological examination realized on all the surgical specimens. Results: On 2109 dissections of the lower laryngeal nerve realized during the surgical operations on the thyroid 95.1% of the cases, the nerve had a single branch;in 4.1% of the cases, the nerve had two branches;and in 0.8% of the cases, the nerve had more than 2 branches. Conclusion: The complications of the thyroid surgery in touch with the hurts of the lower laryngeal nerve are known. However, our study shows that these do not seem to be influenced by the premature division of the lower laryngeal nerve.

External Branch of the Superior Laryngeal Nerve: Anatomy and Operating Hurts

Purpose: Our purpose was to describe the anatomy of the external branch of the upper laryngeal nerve and to estimate the frequency of nerves at risk during the total thyroidectomies sub. Methodology: We realized in the CHU Point G in Bamako a forward-looking study over a period going from September 1st, 2016 till December 31st, 2017. All the patients operated by thyroidectomies subtotals for mild goiters were included to whom a systematic location of the external branch of the superior laryngeal nerve in the space avascular of Reeve was realized. Cancers and other thyroid pathologies were not included. Results: We counted and operated 120 cases of mild goiters. The external branch of the superior laryngeal nerve was seen and dissected in 80.8%;it was not seen in 19.2%. According to the classification of Cernea: the type 2 was found in 80.8% of the cases with him under typical 2b in 47.5% and under type 2a in 40 (33.3%). The global frequency of lesion of the external branch of the upper laryngeal nerve was 10.8% at 9 patients among whom 6 who presented a BENLS of Type Ni. Conclusion: The external branch of the upper laryngeal nerve of type 2 presents a risk of wound because the surgeon treats the upper pedicle at the level of the critical centimeter place over the upper pole of the thyroid. The identification of the nerve during the thyroid surgery is the solution of choice.

Anatomical Dissection of the External Branch of the Superior Laryngeal Nerve to the Laboratory of Anatomy of the Faculty of Medicine of Bamako(Mali)

Aim: This study aimed at describing the anatomical variations of the external branch of the superior laryngeal nerve and at estimating the frequency of nerves at risk during the thyroid surgery. Methodology: We realized a forward-looking study from September, 2016 in May 31st, 2018 in the laboratory of anatomy of the Faculty of Medicine and Odontostomatology of Bamako in Mali. All the fresh anatomical subjects not carrying trauma and or a scar at the level of the previous region of the neck were held. The anatomical subjects were not included presenting a traumatic lesion and\or a scar of the previous region of the neck. Results: We realized 34 dissections of the external branch of the superior laryngeal nerve to 17 deathly subjects (11 men and 6 women with a sex-ratio of 1.8). The average age of the subjects was of 42 years (extremes: 18 and 70 years). Our study allowed highlighting in 100% of the cases, the external branch of the superior laryngeal nerve and the superior thyroid artery so to the right as to the left. On 34 dissected external branch of the superior laryngeal nerve, none had a previous route. However we found 28 nerves (82.4%) having a later route, stuck to the external face of the lower constrictor of the pharynx. These were not mixed with the superior thyroid artery and its branch of division and were situated outside the thyroid capsule. In 17.6% of the cases (6 cases), the nerve had a route mixed in the branch of the superior thyroid artery. These were found inside of the capsule (11.8% adhered to the artery and 5.8% crossed its branch of division). Conclusion: The risk of injury of the external laryngeal nerve during thyroid surgery procedure is never zero. It is more important on the left side.
