Özet
The dorsal scapular nerve (DSN) entrapment neuropathy has recently been recog-nized as a common cause of circumscapular pain and cases of winged scapula. Courseof the nerve is important because the middle scalene muscle is frequently accessedfor surgical treatments. Studies in the literature have not focused on the morphomet-ric relationship of the DSN with the scalene muscles and its relationship with the longthoracic nerve (LTN). The neck regions of 13 adult cadavers were dissected bilater-ally. The relationship of DSN with scalene muscles and LTN was evaluated. Cervicalspinal nerves involved in the formation of the DSN were identified. Three types ofDSN were observed based on the cervical spinal nerves from which it originates, fivetypes of DSN from its relationship with the scalene muscles, and two types of DSNfrom its relationship with the LTN. The distance from where the nerve pierces thescalene muscle to the mastoid process was found to be greater in DSNs originatingfrom C4 and C5 (93.85 ± 4.11 mm,p=0.033). In DSNs not connected with LTN, thedistance from where the nerve pierces the scalene muscle to the superior trunk/C5(12.74 ± 7.73 mm,p=0.008) and the length of the nerve within the scalene muscle(14.94 ± 5.5 mm,p=0.029) were found to be statistically significantly greater. Thetopographic and morphometric anatomy of the proximal part of the DSN is impor-tant, especially for scalene muscles-focused surgical treatments and interscalenenerve blocks. We believe our results may guide clinical approaches and surgery.
