[The inferior laryngeal nerve: anatomical and surgical considerations about 60 thyroidectomy]. / Le nerf laryngé inférieur: considérations anatomiques et chirurgicales à propos de 60 thyroïdectomies.

Thyroid surgery requires a thorough knowledge of cervical anatomy and anatomical variations, in particular of the lower laryngeal nerve, in order to avoid iatrogenic lesions. The objective of our study was to analyze the relationships of the lower laryngeal nerve, the existence of branches of nerve division and a subjective appreciation of the size of the nerve. This is a prospective study of 1 year including 60 patients who underwent thyroidectomy. Sixty patients underwent surgery on the thyroid gland between February 2014 and January 2015 by the same principal operator (10 men and 50 women). The average age of our patients was 51 years. For men were performed 6 total thyroidectomies, 2 left lobo-isthmectomies and 2 right lobo-isthmectomies. For women were performed 33 total thyroidectomies, 8 left lobo-isthmectomies and 9 right lobo-isthmectomies. On the right, the nerve was superficial relative to the artery in 71.6% of cases; it was divided in 33.3% of cases and was abnormally thin in 16.6% of cases. On the left, the nerve was deep in relation to the artery in 83.3% of cases; it was divided in 15% of cases and was abnormally thin in 11.6% of cases. Knowledge of the anatomical variations of the lower laryngeal nerve is essential in thyroid surgery, the risk is particularly important on the right side given the sometimes very small caliber and the existence of branches of division more frequent than on the left side.

Medial migration of the tympanostomy tube: what is the optimal management option?

The tympanostomy tube insertion is the gold standard of treatment for secretory otitis media. Complications are associated with this surgery in 17% of cases. One of the rare but real complications is the medial migration of the tympanostomy tube. To our knowledge, this is the 14th case reported in childhood. Considering this rarity, there is no consensus for the management of this phenomenon. Some authors propose a surgical removal, while others prefer to observe whether the patient is asymptomatic. We reported a case of migration of the tympanostomy tube and described the detailed clinical features and management options. This case report and mini-review will broaden readers the knowledge of medial migration of the tympanostomy tube and may guide the relative treatment of this complication in the future.
