Abstract

AIM: High cervical spinal cord injury is associated with high morbidity and mortality. Traditional treatments carry various complications such as infection, pacemaker failure and undesirable movement. Thus, a secure surgical strategy with fewer complications analogous to physiological ventilation is still required. We hope to offer one potential method to decrease the complications and improve survival qualities of patients from the aspect of anatomy. The purpose of the study is to provide anatomic details on the accessory nerve and phrenic nerve for neurotization in patients with high spinal cord injuries. MATERIAL and METHODS: 38 cadavers (76 accessory and 76 phrenic nerves) were dissected in the study. The width, length and thickness of each accessory nerve and phrenic nerve above clavicle were measured. The distances from several landmarks on accessory nerve to the origin and the end of the phrenic nerve above clavicle were measured too. Then, the number of motor nerve fibers on different sections of the nerves was calculated using the technique of immunohistochemistry. RESULTS: The accessory nerves distal to its sternocleidomastoid muscular branches were 1.52±0.32mm ~1.54±0.29mm in width, 0.52± 0.18mm ~ 0.56±0.20mm in thickness and 9.52±0.98cm in length. And the phrenic nerves above clavicle were 1.44±0.23mm ~ 1.45±0.24mm in width, 0.47±0.15mm ~ 0.56±0.25mm in thickness and 6.48±0.78cm in length. The distance between the starting point of accessory nerve and phrenic nerve were 3.24±1.17cm, and the distance between the starting point of accessory nerve and the end of the phrenic nerve above clavicle were 8.72±0.84cm. The numbers of motor nerve fibers in accessory nerve were 1038±320~1102±216, before giving out the sternocleidomastoid muscular branches. The number of motor nerve fibers in the phrenic nerve was 911±321~1338±467. CONCLUSION: The accessory nerve and the phrenic were similar in width, thickness and the number of motor nerve fibers. And the lengths of accessory nerve were long enough for neuritisation with phrenic nerve.

Özet

AMAÇ: Yüksek servikal spinal kord yaralanması yüksek morbidite ve mortalite ile ilişkilidir. Geleneksel tedaviler enfeksiyon, kalp pili yetmezliği ve istenmeyen hareket gibi çeşitli komplikasyonlar taşır. Bu nedenle fizyolojik ventilasyona benzer ve daha az komplikasyonu olan güvenli bir cerrahi strateji gereklidir. Komplikasyonları azaltmak ve hastaların yaşam kalitesini artırmak için potansiyel bir yöntemi anatomik açıdan sunmak, yüksek spinal kord yaralanması olan hastalarda nörotizasyon için aksesuar sinir ve frenik sinirin anatomik ayrıntılarını sağlamak amaçlanmıştır. YÖNTEM ve GEREÇLER: Çalışmada, 38 kadavranın (76 aksesuar ve 76 frenik sinir) diseksiyonu yapıldı. Klavikula üzerinde her frenik sinir ve aksesuar sinirin eni, boyu ve kalınlığı ölçüldü. Aksesuar sinirin çeşitli noktalarından klavikula üzerindeki frenik sinirin kökeni ve ucuna mesafeler ölçüldü. Daha sonra, immünohistokimya tekniği kullanılarak sinirlerin farklı bölümlerindeki motor sinir liflerinin sayısı hesaplandı. BULGULAR: Sternokleidomastoid kas dallarına distal aksesuar sinirler 1,52±0,32 mm ila 1,54±0,29 mm genişliğinde, 0,52±0,18 mm ila 0,56±0,20 mm kalınlığında ve 9,52±0,98 cm uzunluğunda idi. Klavikula üzerinde frenik sinirler 1,44±0,23 mm ila 1,45±0,24 mm genişliğinde, 0,47±0,15 mm ila 0,56±0,25 mm kalınlığında ve 6,48±0,78 cm uzunluğunda idi. Frenik sinir ile aksesuar sinirin başlangıç noktası arasındaki mesafe 3,24±1,17 cm idi, ve aksesuar sinirin başlangıç noktası ile klavikula üzerinde frenik sinirin ucu arasındaki mesafe 8,72±0,84 cm idi. Aksesuar sinirdeki motor sinir liflerinin sayısı sternokleidomastoid kas dalları ayrılmadan önce 1038±320 ila 1102±216 idi. Frenik sinirdeki motor sinir liflerinin sayısı 911±321 ila 1338±467 idi. SONUÇ: Aksesuar sinir ve frenik sinirin genişlik, kalınlık ve motor sinir lif sayısı benzerdi. Aksesuar sinirin uzunluğu frenik sinir ile nörotizasyon için yeterince uzundu.
