Surgical Techniques for Head and Neck Reconstruction in the Vessel-Depleted Neck.

Facial Plast Surg 2020 Dec 24;36(6):746-752. Epub 2020 Dec 24.

Department of Otolaryngology - Head and Neck Surgery, University of Cincinnati College of Medicine, Cincinnati, Ohio.

The vessel-depleted neck presents a unique and challenging scenario for reconstructive surgery of the head and neck. Prior surgery and radiation often result in significant scarring and damage to the neck vasculature, making identification of suitable recipient vessels for microvascular free tissue transfer exceedingly difficult. Therefore, alternative reconstructive techniques and/or vessel options must be considered to obtain a successful reconstructive outcome for a patient. In this article, we discuss our experience and approach to the management of the vessel-depleted neck, emphasizing the importance of preoperative planning and having multiple backup options prior to surgery. The various preoperative imaging modalities and available options for recipient arteries and veins are presented in detail. Additionally, we discuss modifications of select free flaps to maximize their utility in successful reconstruction. Together with thoughtful preoperative planning, these techniques can help aid the reconstructive surgeon in addressing the complex decisions associated with the vessel-depleted neck.

Current opinions in otolaryngology and head and neck surgery: functional considerations in reconstruction after laryngectomy.

Curr Opin Otolaryngol Head Neck Surg 2020 Oct;28(5):355-364

Department of Otolaryngology Head and Neck Surgery.

Purpose Of Review: To review reconstruction techniques following total laryngectomy, partial laryngopharyngectomy, and total laryngopharyngectomy with an emphasis on long-term swallow and speech outcomes.

Recent Findings: Recent literature has shown that the use of fasciocutaneous free flaps in the reconstruction of laryngectomy defects may lead to improved speech and swallow outcomes as compared with regional or free musculocutaneous flaps. Radial forearm and anterolateral thigh are the most often used fasciocutaneous free flaps, with similar speech and swallow outcomes. Primary closure with myofascial flap onlay yields similar speech and swallow results to fasciocutaneous flaps following laryngectomy that spares sufficient pharyngeal mucosa.

Summary: Whenever reconstructing a salvage laryngectomy defect or a primary laryngectomy defect with mucosal deficiency, current evidence suggests that a fasciocutaneous free flap used to augment pharyngeal volume both improves fistula rates as well as long-term speech and swallow outcomes. When sufficient pharyngeal mucosa is present, myofascial onlay can be considered as well.

Recurrent Primary Intrasellar Paraganglioma.

Case Rep Otolaryngol 2020 26;2020:2580160. Epub 2020 Jun 26.

Department of Otolaryngology - Head and Neck Surgery, Indiana University School of Medicine, 1130 W. Michigan Street, Fesler Hall, Suite 400, Indianapolis, IN 46202, USA.

We describe a case of an 81-year-old male presenting with bitemporal visual field defects and blurry vision in the right eye. The patient was found to have a recurrent primary paraganglioma in the sellar and suprasellar region requiring a repeat transsphenoidal endoscopic resection. Immunohistochemical examination confirmed paraganglioma with the classic zellballen appearance which stained positive for chromogranin, synaptophysin, and S-100 in the periphery. Paragangliomas (PGLs) in the sella turcica are a rare entity; only 19 cases have ever been reported in the literature. PGLs in the sellar region are often misdiagnosed or diagnosed in a delayed fashion. Earlier diagnosis of this locally aggressive tumor and meticulous debulking can prevent morbidity secondary to the tumor's compressive effects. This report highlights the effectiveness of surgical interventions in treatment of paragangliomas. More research is still needed to determine the need for adjuvant therapies such as radiation.
