Objectives. In recent years, conservation laryngeal surgeries, including partial pharyngectomy, have been introduced as an al- ternative procedure for selected cases of hypopharyngeal squamous cell carcinoma (HSCC). Reconstruction of these defects presents a considerable challenge for the surgeon after partial pharyngectomy due to its circumferential nature. In this case report, we represent the innovative “End to side” technique to reconstruct hypopharyngeal defect using the rolled supraclavicular flap after laryngeal-preserving partial pharyngectomy. Methods and Results. A 70-year-old female presented with a history of progressive dysphagia and odynophagia. e evaluations revealed a T3N0M0 SCC of pyriform sinus. e mass was successfully resected through partial pharyngectomy, and the hypopharyngeal defect reconstruction was achieved using the rolled supra- clavicular flap via the “End to side” technique. e patient was discharged after decannulation on day 10. e 3-week barium swallow was performed with no evidence of anastomotic leakage, and the oral feeding was started after NG tube removal. At week 5, complete movement of the true vocal cord on the one side and good phonation and deglutition was observed. ere was no evidence of recurrence after 1 year. Conclusions. Laryngeal-preserving partial pharyngectomy and hypopharyngeal reconstruction with the rolled supraclavicular flap via the “End to side” technique could lead to good oncological and functional outcomes in selected cases of pyriform sinus. 1. Introduction Hypopharyngeal squamous cell carcinoma (HSCC) is an aggressive lesion, presenting the worst prognosis among head and neck cancers with a 5-year survival of approximately 30% [1–4]. Patients usually present with an advanced tumor due to submucosal spread, leading to minimal preliminary mani- festation, but early lymph node involvement and distant metastasis [5, 6]. us, most patients require radical resection (i.e., total pharyngolaryngoesophagectomy (PLE)) resulting in high morbidity and mortality rate (e.g., permanent trache- ostomy leading to phonation dysfunction and impaired swallowing) [7–9]. Recently, chemoradiotherapy treatment (CRT) has gained popularity as the primary treatment of HSCC, although it has several limitations mainly including a high recurrence rate, late toxicity, and short disease-free interval [10–12]. In recent years, conservative surgeries with laryngeal preservation protocols have been introduced as an alter- native procedure for selected cases of invasive HSCC [13, 14]. Partial pharyngectomy, indicated in lesions of the pyriform sinus, is one of these procedures, leading to de- sirable postoperative oncologic and functional outcomes [15, 16] and a 5-year overall survival rate, disease-specific survival rate, and successful laryngeal function preservation of 50, 65%, and 80%, respectively [17]. Reconstruction of the hypopharyngeal defect represents a considerable challenge for the surgeon after partial pharyngectomy due to its circumferential nature [18]. e ideal reconstruction would lead to normal deglutition, Hindawi Case Reports in Otolaryngology Volume 2021, Article ID 6619916, 6 pages https://doi.org/10.1155/2021/6619916
