    Variations of the external branch of the superior laryngeal nerve during its course and its importance in surgical approaches: an experimental cadaveric study
    (Index Copernicus International, 2023) Chatzioglou, Gkionoul Nteli; Sarı, Elif; Gayretli, Özcan; Coşkun, Osman; Öztürk, Adnan; Gürses, İlke Ali; Faculty Member; School of Medicine; 235485
    Introduction: Injury of the external branch of the superior laryngeal nerve can cause a hoarse or weak voice due to the functional loss (dysergia) of the cricothyroid muscle. Defining the anatomical variations of the external branch of the superior laryngeal nerve and estimating their frequency are crucial for surgical interventions. Aim: To reveal the topography of the external branch in the Anatolian population, to prevent injury of it during the surgical intervention in the anterior neck region. Material and Methods: 26 bilateral hemilarynges (4 females, 22 males) were dissected. The morphometric and morphological features of the external branch were examined. The obtained results were compared statistically, left and right. Results: Landmarks such as the thyroid gland and laryngeal prominence were determined for the detection of the external branch. The variations of the course of the external branch and the points of piercing the cricothyroid muscle or inferior pharyngeal constrictor muscle were evaluated. Discussion: Although safe approaches have been described for nerve protection during neck surgeries, injuries may occur during preliminary surgery as the mentioned nerve is thinner and more superficial than other branches of the vagus nerve. However, it can be detected more easily and safely by knowing the defined anatomical landmarks and morphological variations of the external branch. Conclusion: The anatomical variations described can be a safe and important guide in surgeries of the anterior neck region.

    First extensor compartment morphology and clinical significance: a cadaver series study
    (Korean Association of Anatomists, 2023) Coşkun, Osman; Ok, Fatma; Şahin, Büşra; Gürses, İlke Ali; Faculty Member; School of Medicine; 235485
    The first extensor compartment of the wrist is a distinctly variable anatomical area. Anatomical variations in this region contribute to the pathophysiology and treatment failure of de Quervain's disease, which is a kind of tenosynovitis that develops in the first extensor compartment of the wrist. We aim to describe the first extensor compartment morphology, to evaluate the septum frequency, location of the septum, and the number of tendons of abductor pollicis longus (APL) and extensor pollicis brevis muscles (EPB). First extensor compartment of 87 wrists of 45 cadavers were dissected. The presence or absence of septum and number of tendon slips of APL and EPB revealed. The proximal and distal widths of the compartments were measured. Septums were detected in 60.9% (n=53) of the wrists. Incomplete (distal) and complete (proximal) septa were present in 35.6% (n=31) and 25.3% (n=22) of the cases. Only 26.4% of the wrists had a single slip of APL tendon. The Remaining had multiple slips. The median inner width of the proximal and distal compartments in all wrists were calculated as in the order of 9.11±1.14 mm and 8.55±1.12 mm. We believe that understanding the anatomy of the first extensor compartment in the Turkish population would be helpful to surgeons, radiologists, and physiotherapists to diagnose and manage de Quervain's disease.

    Unusual multiple arterial variations of the upper limb
    (Wolters Kluwer, 2022) Candir, Buse Naz; Sağlam, Latif; Gayretli, Özcan; Gürses, İlke Ali; Faculty Member; School of Medicine; 235485
    During routine dissection of a 64-year-old male cadaver, multiple variations were observed in the arteries of the upper extremities. The first part of the axillary artery did not give any branches. The second part, after giving superior thoracic and thoracoacromial arteries divided into deep and superficial brachial arteries. Superficial brachial artery gave lateral thoracic artery and continued into the arm. After giving anterior circumflex humeral artery, the deep brachial artery trifurcated into the subscapular artery, posterior circumflex humeral artery, and profunda brachii artery. Understanding upper limb arterial variations are important for performing safer clinical procedures.
