Accurate knowledge of anatomical variations of the recurrent laryngeal nerve (RLN) provides information to prevent inadvertent intraoperative injury and ultimately guide best clinical and surgical practices. The present study aims to assess the potential anatomical variability of RLN pertaining to its course, branching pattern, and relationship to the inferior thyroid artery, which makes it vulnerable during surgical procedures of the neck. Fifty-five formalin-fixed cadavers were carefully dissected and examined, with the course of the RLN carefully evaluated and documented bilaterally. Our findings indicate that extra-laryngeal branches coming off the RLN on both the right and left side innervate the esophagus, trachea, and mainly intrinsic laryngeal muscles. On the right side, 89.1% of the cadavers demonstrated 2–5 extra-laryngeal branches. On the left, 74.6% of the cadavers demonstrated 2–3 extra-laryngeal branches. In relation to the inferior thyroid artery (ITA), 67.9% of right RLNs were located anteriorly, while 32.1% were located posteriorly. On the other hand, 32.1% of left RLNs were anterior to the ITA, while 67.9% were related posteriorly. On both sides, 3–5% of RLN crossed in between the branches of the ITA. Anatomical consideration of the variations in the course, branching pattern, and relationship of the RLNs is essential to minimize complications associated with surgical procedures of the neck, especially thyroidectomy and anterior cervical discectomy and fusion (ACDF) surgery. The information gained in this study emphasizes the need to preferentially utilize left-sided approaches for ACDF surgery whenever possible.

Piriformis syndrome is a neuromuscular pain syndrome occurring as a result of compression on the underlying sciatic nerve due to various causes including the hypertrophy, inflammation, mass lesions or anatomical variations occuring in the deep gluteal space. Patients with piriformis syndrome often experience pain and numbness in the hip, thigh and leg, similar to those of sciatica. In addition to clinical findings, electrophysiological examinations and magnetic resonance imaging (MRI) is useful for diagnosis. Once diagnosed, the treatment approach is stepwise and conservative treatment is successful in majority of cases. Surgical treatment should be performed for the cases in whom conservative treatment methods fail and when the sciatic nerve should be decompressed. Surgery is an important treatment option for unresolved piriformis syndrome with its simplicity and low morbidity. Several surgical procedures have been described for the decompression of affected sciatic nerve. Due to excessive fibrosis tissue that may be developed around the sciatic nerve in classical surgical procedures, person's return to social and work life may be delayed. In the present study, we will evaluate the surgical indication criteria of our cases who underwent minimally invasive surgical treatment due to piriformis syndrome, the definition of the surgical procedure and the outcomes.

Background Recently, thoracoscopic resection of pulmonary sequestration has become more common, since resection of an aberrant artery using an end-stapler is a safe maneuver in many cases. However, injury of the vessels can lead to major hemorrhage. We reported our surgical experience based on thoracoscopic surgery, with five cases of interlobar pulmonary sequestration, focusing on precautions for aberrant arterial vessels. Object and methods We performed pulmonary resections for five patients with interlobar pulmonary sequestration in a lower lobe (left, n = 4; right, n = 1) between April 2004 and May 2020. All aberrant vessels were derived from the lower thoracic artery. Two patients had a single aberrant artery and three had multiple. In four patients, these vessels were detected before surgery, and pulmonary sequestration was diagnosed in four. In one elderly patient, the aberrant vessel was overlooked, and lung cancer was suspected before surgery. Angiography or multidetector-row computed tomography was subsequently performed in four cases. The surgical plan was determined according to the location and size of the pulmonary lesion and three-dimensional images of aberrant vessels. Result In all patients, approaches were made thoracoscopically. Hemorrhage from an anomalous vessel was encountered in one case. Pulmonary resections included two lobectomies and three limited resections. Angioplasty for the root of anomalous branches was performed following pulmonary resections under converted minimal lateral thoracotomy in two cases. Conclusion Preoperative assessment of the anatomical variations in abnormal vessels is essential to achieve safe surgical procedures. According to the situation of the aberrant vessels, selecting surgical procedures with consideration of potential subsequent complications arising over a long period of time is important.

Sternalis Muscle

AbstractRectus sternalis muscle, either unilateral or bilateral is an uncommon anatomical variant among the anterior chest wall muscles. During the routine dissection as a part of undergraduate medical teaching in the department of Anatomy, a unilateral rectus sternalis muscle was noticed on the right hemi thorax in one cadaver, located adjacent to the sternum between the pectoralis major muscle and the superficial fascia of the region. Though rare in occurrence, when present, rectus sternalis muscle demands proper awareness and attention by the clinicians especially radiologists and surgeons, as the ignorance of the existence of this muscle may lead to misinterpretation, incorrect diagnosis and unnecessary clinical interventions. Such anatomical variations should be borne in mind while doing radiological investigations, radiotherapy and surgical procedures in the chest region.

A sound knowledge of anatomical variations that could be encountered during surgical procedures is helpful in avoiding surgical complications. The current article details anomalous morphology of inferior alveolar nerves encountered during routine dissection of the craniofacial region in the Gross Anatomy laboratory. We also report variations of the lingual nerves, associated with the inferior alveolar nerves. The variations were documented and a thorough review of literature was carried out. We focus on the variations themselves, and the clinical implications that these variations present. Thorough understanding of variant anatomy of the lingual and inferior alveolar nerves may determine the success of procedural anesthesia, the etiology of pathologic processes, and the avoidance of surgical misadventure.
