Number, location and surrounding structures of parathyroid glands with emphasis on parathyroidectomy were studied on 101 cadaverous bodies. Number of collected samples from all known locations of parathyroid glands varied from three to five in one individual, with mean 3.71 +/- 0.62. We identified 80% of samples as parathyroid glands. Mean number of correctly identified parathyroid glands in on...

The authors report the case of a 55-year-old female, hypertensive, smoker patient presenting with dysphonia, dysphagia and persistent dry cough. Laryngoscopy diagnosed left vocal cord paralysis. Computed tomography demonstrated saccular aneurysm of the inferior wall of the aortic arch, stretching the left recurrent laryngeal nerve, a finding compatible with Ortner's syndrome.

The recurrent laryngeal nerve (RLN) has many anatomical variations and various relations with adjacent structures. Identification and total exposure of the cervical part of the RLN was performed during operations on the thyroid gland. An extremely rare anatomical variation of the nerve was encountered during the surgical procedure. Coexistence of both right RLN and non-RLN was observed in one p...

Precise localization of the third molars in relation to the inferior alveolar nerve canal is critical from a clinical point of view and strongly affects the surgical treatment outcome. Recently, by using three-dimensional modeling software, the relationship of third molar root apices and inferior alveolar nerve canal can be better understood. In this study, the spatial relationship of two surgi...

OBJECTIVES/HYPOTHESIS To enhance understanding of spontaneous laryngeal muscle reinnervation following severe recurrent laryngeal nerve injury by testing the hypotheses that 1) nerve fibers responsible for thyroarytenoid muscle reinnervation can originate from multiple sources and 2) superior laryngeal nerve is a source of reinnervation. STUDY DESIGN Prospective, controlled, animal model. M...

The most serious complications of total thyroidectomy, in cases of widespread and invasive diseases, are mainly hypoparathyroidism and laryngeal inferior nerve palsy. Lesions of the external branch of superior laryngeal nerve instead, although less obvious than the those caused by the recurrent laryngeal nerve lesions, have been taken less into consideration. The frequency of this lesion varies...
