A STUDY TO OBSERVE THE VARIATIONS IN THE POSITION OF THE RECURRENT LARYNGEAL NERVE IN RELATION TO THE TRACHEO- OESOPHAGEAL GROOVE
Journal Title: Stanley Medical Journal - Year 2016, Vol 3, Issue 2
Abstract
The relation of the recurrent laryngeal nerve with tracheo-oesophageal groove is highly variable making it vulner - able to injury during surgical manipulation of the neck. 70 Recurrent laryngeal nerves were dissected in 20 cadavers from department of Anatomy, Government Stanley medical college and 15 post-mortem en-bloc specimens from Institute of Forensic medicine, Government Stanley medical college. The relation of the recurrent laryngeal nerve with the tracheo- oesophageal groove was studied at two different levels; 1. At a level 2cms below the lower border of the cricoid cartilage. 2. At a level 1cm below the lower border of the cricoid cartilage. The results were tabulated and analyzed by tests for the significance of the difference in the proportions. At 2cms below the lower border of cricoid cartilage, 36 out of 70(51.4%) were seen in para tracheal position, 34 out of 70(48.6%) were within tracheo oesophageal groove. At 1cm below lower border of the cricoid cartilage, 59 out of 70(84.3%) were within the tracheo oesophageal groove, 11 out of 70(15.7%) were in the para tracheal position. The Chi – Square test showed statistically significant difference in the relationship of recurrent laryngeal nerve with tracheo oesophageal groove in the right and left side in both 2cm below (P < 0.02) and 1cm below (P<0.029) the lower border of cricoid cartilage. The significant variations observed in the relationship of the recurrent laryngeal nerve with the tracheo-oesophageal groove in the right and left side would be important for surgeons who do thyroidectomy and other neck surgeries.
