PURPOSE To carry out an anatomic study of superior laryngeal nerve in not preserved in formaldehyde and not frozen corpses. METHODS Thirty-eight male corpses from the Minas Gerais Medico-legal Institute (IML) were studied. In 18 corpses dissection was performed bilaterally and in 20 only on the left side, total number 56 nerves dissected. Their descriptive segments measurements and the anatom...

Total thyroidectomy is nowadays the operation of choice in the majority of endocrine surgery centers, whether the pathology is benign or malignant. To obtain good results, a thorough knowledge of local anatomy and a profound respect for hemostasis are necessary. Routine, at least visual, identification of the inferior laryngeal nerve (ILN) is considered gold standard and is strongly recommended...

BACKGROUND Injury of the inferior laryngeal nerve is not the only cause of voice alteration after thyroidectomy; many patients notice minimal changes immediately after operation, without evidence of inferior laryngeal nerve damage. We hypothesized that there may be other causes for voice modification, such as injuries of the superior laryngeal nerve, prethyroid strap muscles, and cricothyroid m...

INTRODUCTION The incidence of damage to the individual cranial nerves and their branches associated with laryngeal mask airway use is low; there have been case reports of damage to the lingual nerve, hypoglossal nerve and recurrent laryngeal nerve. To the best of our knowledge we present the first reported case of inferior alveolar nerve injury associated with laryngeal mask airway use. CASE ...

In this case report, we present a with an unusually high course of inferior thyroid artery and its relationship the recurrent laryngeal nerve on right side neck 91 years-old formalin fixed male cadaver. Dissection showed that gave off branches between following sharp curvature descending downward to gland. Knowledge such variation location is important for surgical radiological procedures.

introduction: injury to cranial nerves ix, x, and xii is a known complication of laryngoscopy and intubation. here we present a patient with concurrent hypoglossal and recurrent laryngeal nerve paralysis after rhinoplasty. case report: the patient was a 27-year-old woman who was candidate for rhinoplastic surgery. the next morning after the operation, the patient complained of dysphonia and a s...

The recurrent inferior laryngeal nerve (RILN) origins from the vagus trunk and, recurring into the mediastinum, courses then into the larynx. Sometimes this nerve can assume an unusual pathway, coursing directly into the larynx. This anomaly is the so-called non-recurrent inferior laryngeal nerve (NRILN) and represents a rare entity, with an incidence between 0.3% and 1.6%. It is commonly cause...

most often in the posterior of the mandible of patients who need implants, the inferior alveolar nerve (ian) is too high to insert the implants, and the surgeons have to reposition ian. in conventional techniques (to make the windows in the buccal aspect of the mandible) removal of the corticocancellous bone may cause weakness of the mandible. here we present a new technique in which the bone i...
