A new designed self-expandable metal stent for the management of benign radiotherapy-induced hypopharyngeal or cervical esophageal strictures.

BACKGROUND AND AIMS: The management of patients with hypopharyngeal or cervical esophageal refractory benign strictures (RBS) after surgery and radiotherapy ± chemotherapy for laryngeal cancer is challenging. We aimed to assess the long-term efficacy and safety of a new designed fully covered SEMS in these patients. METHODS: We reviewed the results of a prospectively collected database of 40 consecutive patients with dysphagia due to RBS of the cervical esophagus or hypopharynx after surgery and radiotherapy with or without chemotherapy for laryngeal cancer, unfit for surgery, referred in two tertiary-care endoscopic centers from June 2005 to December 2018. All of them were treated with placement of a Niti-S Conio cervical stent. RESULTS: After placement of the first stent, dysphagia improved in all patients. The total number of adverse events was 35 out of a total of 299 procedures (11.7%): 25 (8.4%) stent migrations, 6 (2%) tumor overgrowth, 3 severe pain and 1 pharyngo-cutaneous fistula. Stents were periodically changed. In only one patient with a cervical esophageal stricture the stent was definitively removed after 7 sessions of stent placement because of stricture resolution. Patients were followed-up for a median of 11.6 months and a significant improvement in dysphagia was reported in all patients (p < 0.001). CONCLUSIONS: The use of this conformable, small caliber new designed Niti-S stent, exchanged periodically, appeared safe and permitted durable oral intake in patients with difficult-to-treat hypopharyngeal or cervical esophagus strictures, avoiding the need for periodic dilations.

Development of a decellularized hypopharynx with vascular pedicle scaffold for use in reconstructing hypopharynx.

BACKGROUND: Hypopharynx reconstruction after hypopharyngectomy is still a great challenge. Perfusion decellularization is for extracellular matrix (ECM) scaffolding and had been used in organ reconstruction. Our study aimed to prepare an acellular, natural, three-dimensional biological hypopharynx with vascular pedicle scaffold as the substitute materials to reconstruct hypopharynx. RESULT: Scanning electron microscope and histology staining showed that the decellularized hypopharynx with vascular pedicle scaffold retained intact native anatomical ECM structure. Myoblasts were observed on the recellularized scaffolds with bone marrow mesenchymal stem cells induced by 5-azacytidine implanted in the rabbit greater omentum by immunohistochemical analysis. CONCLUSION: The decellularized hypopharynx with vascular pedicle scaffold prepared by detergent perfusion in our study has a potential to be an alternative material to pharynx reconstruction.

Reconstruction of hypopharyngeal defects with anterolateral thigh free flap: A single-center retrospective analysis.

INTRODUCTION: Reconstruction of expanded hypopharyngeal defects following laryngo-hypopharyngectomy for surgical treatment of primary is still a challenge for head and neck surgeons. Tradiotionally, jejunal or radial forearm flaps are the common reconstructive choice. Recently, the anterolateral thigh (ALT) free flap has served for pharyngoesophageal reconstruction. The goal of this work is to describe a retrospective analysis about a five-year single-center experience in the reconstruction of post-operative hypopharyngeal defects with ALT free flap. METHODS: A single-center retrospective study was performed, including patients treated for patients who underwent tumor surgery involving hypopharynx with ALT free flap reconstruction from 2015 to 2020. Exclusion criteria were paediatric (0-18 years) patients, and the absence of follow-up. RESULTS: The study included 23 adult patients. The mean size of the flap was 90 cm2 (range 60-130 cm2). The mean time required to harvest the antero-lateral tight flap was 70 min (range 35-120 min). The median age was 46.3 years (SD 15.81, range: 19-84 years), with a gender female prevalence (F = 48, M = 33). Mean follow-up was 77.7 months (min 4-max 361, SD 72.46). One patient (4.4 %) showed a hypopharyngeal stenosis. CONCLUSION: ALT free flap represents a successful and versatile reconstructive option for hypopharyngeal defects extended to oropharynx and/or larynx following total laryngectomy with circumferential or partial hypopharyngectomy, regardless of the functional and aesthetic results, with minimal donor-site complication.

Transoral management of pharyngeal ballistics.

OBJECTIVE: To present a case of a ballistic foreign body in the pharynx after a gunshot wound to the maxillofacial area, an accompanying review of relevant literature, and our approach to management. METHOD: A 68-year-old male with no prior medical history presented to our trauma center with gunshot wounds to the left chin, left wrist, right chest, and sternum. A CT Angiogram of the neck revealed a bullet fragment left neck and additional fragment adjacent to the L hypopharynx at the level of the hyoid. The patient was taken to the operating room for direct laryngoscopy with foreign body removal and esophagoscopy. RESULTS: We document our workup and successful surgical removal of the pharyngeal ballistic foreign body via our video abstract, compiling preoperative imaging, intraoperative imaging, and video. Literature review of the subject accompanying our video abstract highlights the extensive complications that can occur from a retained foreign body in this area, supporting surgical removal of the foreign body if safely possible. CONCLUSION: Given the demonstrated feasibility and success of endoscopic foreign body removal from the pharyngoepiglottic space, in addition to overwhelming support for removal in the literature we recommend surgical extraction of ballistic foreign bodies located in the upper aerodigestive tract in stable patients to avoid early and long-term complications that can impact swallowing function, airway stability and the vital structures contained within the neck.

Adipofascial anterolateral thigh free flap in hypopharyngeal and oropharyngeal reconstruction.

BACKGROUND: The anterolateral thigh (ALT) flap is a popular choice for head and neck reconstruction surgery, but its ungainly thickness makes it of limited value in some intracavitary reconstructions. The ALT adipofascial flap is an improved flap without skin or muscle. Here, we seek to further illustrate the ALT adipofascial flap as an alternate method of hypopharyngeal and oropharyngeal reconstruction in head and neck. METHODS: A retrospective review of 9 patients (7 men, 2 women) ranging from 28 to 67 years (mean age, 53.1 years) who underwent reconstruction with the ALT adipofascial flap after hypopharyngeal carcinoma (4 patients) or oropharyngeal carcinoma (5 patients) resections from August 2018 to December 2019 was performed. Surgical outcomes and functional resoration were assessed. RESULTS: The size of the flaps ranged from 6 × 4 cm2 to 6 × 12 cm2 . The average flap thickness was 0.14 cm (range, 0.1-0.2 cm) and the average pedicle length was 9.8 cm (range, 7-12 cm). The postoperative course was uneventful in eight patients. Reconstruction was successful in all cases during 7-23 months of follow-up (mean time, 14.3 months). All patients resumed oral feeding for 2-8 weeks (mean time, 4.9 weeks) and the tracheal cannula was successfully removed 0.5-4 months postsurgery (mean time, 2.4 months). CONCLUSION: The ALT adipofascial flap is a viable choice for hypopharyngeal and oropharyngeal reconstructions and is thinner than the ALT flap. It could be harvested as a single-pedicled double-island flap for complex defect reconstruction.

Efficacy of free anterolateral thigh flap and free jejunum in reconstruction for hypopharyngeal and cervical esophagus. / æ¸¸ç¦»è‚¡å‰å¤–ä¾§çš®ç“£å’Œæ¸¸ç¦»ç©ºè‚ é‡å»ºä¸‹å’½é¢ˆæ®µé£Ÿç®¡çš„ç–—æ•ˆ.

OBJECTIVES: Because of its peculiar anatomical location, most patients with hypopharyngeal and cervical esophageal cancer are at advanced stage when they visit the hospital. At present, the treatment for hypopharyngeal and cervical esophageal cancer is primarily surgical resection and radiotherapy. However, due to the wide range of surgical resection, it can often lead to a large range of annular defects. Therefore, the upper digestive tract reconstruction after tumor resection is very important. We use the free anterolateral thigh flap (ALT) and free jejunum (FJ) transfer to reconstruct the hypopharyngeal and cervical esophagus, and to investigate the effect of both reconstruction methods on upper gastrointestinal tract defects. METHODS: A retrospective analysis was conducted to investigate the clinical data of 42 patients with hypopharyngeal and cervical esophageal cancer (Clinical Stage IV) from Jan. 2004 to Jan. 2016 in the Second Xiangya Hospital of Central South University. All patients underwent total laryngopharyngectomy and cervical esophageal resection. The hypopharyngeal circumferential and cervical esophageal defects were reconstructed with free ALT (n=22) or FJ (n=20). Four patients who underwent radiotherapy and chemotherapy before surgery did not receive radiotherapy or chemotherapy after surgery. The remaining 38 patients underwent postoperative radiotherapy and chemotherapy. All patients were followed up by telephone or outpatient review, with a follow-up deadline in Jan. 2021. We compared the differences between the 2 groups in postoperative complications, radiotherapy complications, and survival rate. The differences in individual characteristics between 2 groups were analyzed using Fisher test. The differences in postoperative and radiotherapy complications between two groups were analyzed using χ² test. The 3- and 5-year overall survival rates were calculated using Kaplan-Meier survival curve method. RESULTS: In the ALT group, the postoperative complications mainly included anastomotic fistula, chylous fistula and subcutaneous hematoma of the donor site. The radiotherapy complication was anastomotic stenosis. However, in the FJ group, the postoperative complications mainly included chylous fistula, intestinal obstruction, and intestinal fistula. The radiotherapy complications mainly contained anastomotic fistula and tissue flap necrosis. The cases of postoperative complications in the ALT group and the FJ group were 7 and 5, respectively (P=0.625), and the cases of radiotherapy complications were 3 and 4, respectively (P=0.563). The 3-year overall survival rates in the ALT group and the FJ group were 52.9% and 46.7%, respectively, and the 5-year total survival rates were 35.1% and 31.9%, respectively (P=0.53). The cases of anastomotic stenosis after radiotherapy in the ALT group were more than those in the FJ group (P=0.097). However, the cases of jejunal necrosis and anastomotic fistula after radiotherapy in the FJ group were more than those in the ALT group (P=0.066). CONCLUSIONS: There are no significant differences in postoperative and radiotherapy complications and 3-and 5-year survival rates between the ALT group and the FJ group. The reconstruction with ALT is prone to develop anastomotic stricture. The reconstruction with FJ cannot withstand high-dose radiotherapy. The ALT and FJ are effective methods in the reconstruction of hypopharynx and cervical esophagus. The treatment protocol should be carefully chosen based on its advantages and disadvantages of these 2 methods.

Preclinical experience with a novel single-port platform for transoral surgery.

BACKGROUND: We investigated a novel minimally invasive surgical platform for use in the oropharynx, hypopharynx, and larynx for single-port transoral surgery used in concert with standard transoral laryngeal and pharyngeal instrumentation. METHODS: The preclinical investigational device by Fortimedix Surgical B.V. (Netherlands) features two channels for manually controlled flexible articulating surgical instruments. A third central channel accepts both rigid and flexible endoscopes. The system is coupled to a standard laryngoscope for transoral access. In three cadaver models, we evaluated the surgical capabilities using wristed grasping instruments, microlaryngeal scissors, monopolar cautery, and a laser fiber sheath. Procedures were performed within the oropharynx, supraglottis, glottis, subglottis, and hypopharynx. RESULTS: Within the oropharynx, we found adequate strength, range of motion, and dexterity to perform lateral oropharyngectomy and tongue base resection. Within the larynx, visualization was achieved with a variety of instruments including a flexible, 0° and 30° rigid endoscope. The glottis, supraglottis, pyriform sinuses, post-cricoid space, and esophageal inlet were readily accessible. Visualization and manipulation of grasping, laser, and monopolar cautery instruments were also possible within the subglottis. Instrument reach and accuracy facilitated completion of a delicate micro-flap on the true vocal fold. Other procedures included vocal fold resection, cricopharyngeal myotomy, and resection of subglottic mucosa. CONCLUSIONS: From this initial proof of concept experience with this novel platform, we found a wide range of procedures within the oropharynx, larynx, and hypopharynx to be feasible. Further work is needed to evaluate its applicability to the clinical setting. The ability of this platform to be used with conventional instrumentation may provide an opportunity for complex transoral surgery to be performed in a facile manner at greatly reduced cost.

Trans-hyoid hyoidthyroidpexy: A modified technique for selected cases of obstructive sleep apnea.

OBJECTIVE: Hypopharyngeal collapse (HC) considered a challenge in surgery of obstructive sleep apnea (OSA). Several procedures were presented to deal with HC indirectly via providing support to the lateral walls of the hypopharynx preventing transverse collapse but hyoidthryoidpexy had gained more popularity. The procedure aimed to fix the mobile hyoid bone to a rigid mid-line neck structure, thus preventing the bone and its attached muscles from collapsing during sleep with the negative intrathoracic pressure on inspiration. STUDY DESIGN: A prospective case series study. METHODS: From April 2018 to January 2020, A Modified Technique of Trans hyoid hyoidthyroidpexy was applied for all included patients (24) patients with symptoms of OSA showing predominant lateral wall collapse of the hypopharynx (with retro-palatal collapse) with other OSA surgery. RESULTS: 6-8 months postoperatively, the Apnea Hypopnea index dropped from 43.75 ± 8.44 to 16.28 ± 7.35 (P < 0.0001; t = 10.6988). 14 patients (58.33%) were reported as successful while 7 patients (29.17%) were considered responders and three patients (12.5%) were considered non responders. The mean lowest oxygen desaturation elevated from 77.56 ± 5.64 to 92.38 ± 6.25 (p < 0.0001). Epworth Sleepiness Scale improved (P < 0.0001) from 16.85 ± 4.23 to 5.17 ± 3.89. CONCLUSION: Trans-hyoid hyoidthyroidpwxy is a modified technique of hyoidthyroidpexy. The procedure reported good outcomes in treating OSA. It is a simple, cost-effective and less traumatic technique. It could be combined with other multilevel surgical procedures.

Comparison of salvage surgery for recurrent or residual head and neck squamous cell carcinoma.

OBJECTIVE: Concomitant chemoradiation therapy is a standard treatment for head and neck cancer. Thus, salvage surgery has become a necessary treatment. The aim of the study was to evaluate the results of salvage surgery by each site of the head and neck, especially the oropharynx, hypopharynx and larynx. METHODS: This was a retrospective, single-institute study. The primary endpoint was overall survival. Secondary endpoints were disease-free survival, the locoregional control rate after salvage surgery, the indication rate for salvage surgery, the reasons for contraindications to salvage surgery, the post-operative complication rate and the predictors of survival. RESULTS: Three-year overall survival after salvage surgery was 58.8% in the salvage surgery group and 8.59% in the other treatment group (P < 0.0001). Regarding overall survival and disease-free survival after salvage surgery, there was no difference among sites. Regarding locoregional control rate among sites, there was no significant difference. The oropharyngeal cancer group had the lowest rate of salvage primary resection. Surgical margin and local and regional recurrence or residual disease were predictors on univariate and multivariate analyses. CONCLUSIONS: Salvage surgery is effective for recurrent or residual cases after concomitant chemoradiation therapy. For oropharyngeal cancer, local control is important, and for oropharyngeal cancer and hypopharyngeal cancer, distant metastasis is important.

Treatment patterns and survival outcomes of advanced hypopharyngeal squamous cell carcinoma.

BACKGROUND: This study evaluated the treatment outcomes of the primary surgery (PS) or concurrent chemoradiotherapy (CCRT) as the initial treatment for hypopharyngeal squamous cell carcinoma (HPSCC). METHODS: This retrospective cohort study included patients with stages III-IV HPSCC from four tertiary referral centers consecutively enrolled from 2003 to 2012; of them, 213 (32.6%) and 439 (67.4%) had received PS and CCRT as their primary treatments, respectively. The 5-year overall survival (OS) and disease-free survival (DFS) rates were analyzed using the Kaplan-Meier method and Cox regression models. RESULTS: In patients undergoing PS and CCRT, OS rates were 45.0% and 33.1% (p < 0.001), respectively, and DFS rates were 36.2% and 28.9% (p = 0.003), respectively. In subgroup analysis, in patients with stage IVA HPSCC, PS was associated with higher OS rate (p = 0.002), particularly in those with T4 or N2 classification (p = 0.021 and 0.002, respectively). Multivariate analysis indicated that stage IVA HPSCC, stage IVB HPSCC, and CCRT were independent adverse prognostic factors for OS rate (p = 0.004, < 0.001, and 0.014, respectively). Furthermore, in patients with stage IVA HPSCC aged ≥ 65 years and with N2 classification, CCRT was significantly associated with lower OS rates than was PS (p = 0.027 and 0.010, respectively). CONCLUSIONS: In patients with advanced HPSCC, PS was significantly associated with better prognosis than CCRT. PS could be a favorable primary treatment modality for the management of patients with stage IVA HPSCC, particularly those aged ≥ 65 years and with T4 and N2 classification.

Is nasogastric tube feeding necessary after hypopharyngeal diverticulum surgery?

OBJECTIVES: Nasogastric tubes (NGT) are often placed after surgery for cricopharyngeal muscle pathology due to risk of infection and mediastinitis. The aim of this study was to examine if this practice is necessary. METHODS: A retrospective case series of subjects who underwent surgery for hypopharyngeal diverticula or cricopharyngeal bars from March 2011 to June 2018 was conducted. Demographic data, type of surgery, placement of feeding tube, initiation of oral feeding, and any complications were recorded. RESULTS: Sixty-four surgeries were performed for Zenker's diverticula (ZD; N = 52), Killian-Jamieson diverticula (N = 2), and cricopharyngeal bar (N = 10). Mean age and ZD pouch size were 74.0 ± 10.6 years and 3.1 ± 1.8 cm, respectively. Procedures included 48 carbon dioxide laser-assisted myotomies, 14 open diverticulectomies, and 2 endoscopic stapler-assisted diverticulotomies. Of the 64 patients, 19 (29.7%) received intraoperative NGTs while the remaining 45 (70.3%) did not receive NGTs. The former cohort had the NGTs removed on post-operative day (POD) 4.5 ± 2.5, and the non-NGT cohort started clear liquid diet (CLD) on POD 1.2 ± 0.7 days, where 38 patients (84.4%) started CLD on POD 1, and 5 patients (7.8%) were started on oral diet on POD 2-4. Over time, fewer NGTs were placed and oral diets were started sooner. There were 5 complications occurring in 3 patients from the NGT cohort (15.5%) and 2 from the non-NGT cohort (4.4%). CONCLUSIONS: Surgery for hypopharyngeal diverticula and CPB may not require routine perioperative NGT placement which can be associated with higher rates of complication. Patients can safely receive CLD on POD 1.

Treatment results of 99 patients undergoing open partial hypopharyngectomy with larynx preservation.

OBJECTIVE: Hypopharyngeal cancers frequently go undetected until advanced stages. However, recent advances in endoscopic technology have enabled earlier detection of hypopharyngeal cancer. We evaluated the effectiveness of larynx-preserving surgery for hypopharyngeal cancer. METHODS: We retrospectively analyzed 99 patients with hypopharyngeal squamous cell carcinoma who underwent partial hypopharyngectomy with larynx preservation between September 1992 and December 2009 at the National Cancer Center Hospital East. Of these, 91 patients underwent larynx-preserving surgery as initial treatment; eight patients underwent salvage surgery for recurrent disease after previous radiotherapy. Also, 9 of our patients had undergone previous radiotherapy in the head and neck for a different cancer. Before surgery, the TNM stage and tumor location was recorded. Free-flap reconstruction was performed in 60 patients, while the hypopharyngeal mucosa was closed without a free flap in 39 patients. RESULTS: The 5-year overall survival rate in our cohort was 66.9%, and 59 patients are currently alive without recurrence. Thirty-three patients died due to primary recurrence (n = 5), regional recurrence (n = 10), distant metastasis (n = 9), postoperative death (n = 1), and unrelated disease (n = 8). Laryngeal function could not be preserved in 19 patients, 2 of whom had undergone previous radiotherapy, and 7 of whom had undergone both previous radiotherapy and other salvage surgeries. CONCLUSION: Partial hypopharyngectomy can preserve laryngeal function in patients with pharyngeal cancer with careful patient selection.

Surgical management around the paratracheal area of hypopharyngeal cancer.

OBJECTIVE: We aimed to clarify the suitable surgical management around the paratracheal area of patients who undergo total pharyngolaryngectomy based on the pathological results of hypopharyngeal cancer. METHODS: The study was conducted under a multicenter, retrospective observational design in Japan. We analyzed histopathological paratracheal lymph node metastasis and thyroid invasion, and recurrence around the paratracheal area for 184 patients who underwent initial surgery among 280 participants. RESULTS: There were significant differences in the frequency of metastasis to paratracheal lymph nodes as cN advances (P = 0.0344) and cT advances (P = 0.00028). By subsite, the paratracheal lymph node metastasis ratio was 22/130 patients (16.9%) in piriform sinus (PS), 8/32 (25.0%) in PW, 5/22 (22.7%) in PC and 10/17 (58.8%) in cervical esophagus (Ce+). The ratio of cases with bilateral paratracheal metastasis tended to be higher in cN2c, posterior wall (PW) and postcricoid (PC). Invasion to the thyroid was histopathologically confirmed in 16/184 patients (8.7%). Invasion from the primary lesion was in 15 patients. CONCLUSION: This study indicates that it is better for patients with advanced hypopharyngeal cancer at minimum undergo ipsilateral paratracheal lymph node dissection. Tumor subsite of PW, PC or cN2c disease or disease extending to the Ce+ should be treated with bilateral paratracheal neck dissection. In order to more reliably perform paratracheal dissection, there is also an option to resect the thyroid lobe in the range of dissection. Preservation of the thyroid gland can be considered if invasion into the thyroid gland has been clearly ruled out.

Anesthesia and ventilation options for flex robotic assisted laryngopharyngeal surgery.

BACKGROUND: Transoral treatment of benign and malignant lesions of laryngopharynx has limitations in exposure and access, partially due to the endotracheal tube (ETT). With a proper airway control to tailor ventilation and maximize exposure, transoral Flex robotic surgery (FLEX), using its 3D camera and instruments, can expand its ability. Choosing the right ETT, including a novel concept of using jet ventilation (JV) in FLEX, and placement technique can allow augmentation of the advantages that robotic surgery offers. METHODS: Chart review of FLEX assisted procedures was performed. Attention was given to demographics, all events of airway manipulation and ventilation type, procedures performed and outcomes including adverse effects. RESULTS: Fifty-two patients underwent eighty procedures. The airway was manipulated sixty-four times to include 8 JV. All possible FLEX instruments including CO2 laser were used. Three novel possible indications for trans-oral robotic surgery including the feasibility of JV in FLEX procedures were shown. CONCLUSIONS: Lesions of the tongue base, hypopharynx, larynx and trachea have the possibility to be managed with adequate exposure with minimal obstruction from ETT. Robotic HD camera permits both the surgeon and anesthesiologist to observe surgery and safely monitor the airway. An algorithm was developed for selecting ideal ventilation method for different procedures. The FLEX and the utilization of JV allows flexibility of two instruments without obstruction.

Treatment for postchemoradiotherapy hypopharyngeal stenosis: Pharyngoesophageal bypass using an anterolateral thigh flap-A case report.

Radiation-induced pharyngoesophageal stenosis is a frequent and unwanted consequence of nonsurgical treatment of hypopharyngeal carcinomas. Current treatment mainly includes endoscopic dilatations, but a poor response to this modality and/or a severe stenosis may lead to a radical resection (pharyngolaryngectomy) and reconstruction with tubed flaps, which allow oral feeding but fail to preserve speech. In this report, we present a case of radiation-induced hypopharyngeal stenosis treated with a pharyngoesophageal bypass using an anterolateral thigh (ALT) flap with the intention of preserving the larynx. We describe the case of a 59-year-old male with severe pharyngoesophageal stenosis after chemoradiotherapy due to a squamous cell carcinoma, where conventional dilatation treatment failed to restore pharyngoesophageal passage of solids or liquids. Since the patient rejected a pharyngolaryngectomy due the loss of speech entailed, a pharyngoesophageal bypass was performed using an ALT flap. The flap measured 13 × 20 cm, which ensured a 4-cm-diameter tube and enough length to communicate the lateral pharyngeal wall with the cervical esophagus. Endoscopy did not reveal flap failure, and during the immediate postoperative period, the patient had a small cervical leak detected only by imaging that did not affect the skin and resolved with antibiotic treatment. The patient also required a tracheostomy on day 4 and initially had no passage of saliva through the bypass; we attributed this to edema that resolved spontaneously after 1 month with complete liquid and solid passage and laryngeal competence that led to tracheal decannulation. Good functional results were achieved both for speech and swallowing at 5-year follow-up. We believe that this procedure may be considered before performing a pharyngolaryngectomy for the treatment of a persistent benign stenosis in patients with a functional larynx.

Reconstruction of laryngopharyngectomy defects: Comparison between the supraclavicular artery island flap, the radial forearm flap, and the anterolateral thigh flap.

OBJECTIVES: The purpose of this study was to evaluate the application of the supraclavicular artery island flap (SCAIF) for the reconstruction of laryngopharyngectomy defects in comparison with reconstructions with the anterolateral thigh flap (ALT) and the radial forearm flap (RFF). PATIENTS AND METHODS: A retrospective study was performed. We compared indications for surgery, reconstructive techniques, operative time, time of hospitalization, and complication rates between patients treated with SCAIF, RFF and ALT following laryngopharyngectomy. Seventy-seven patients were included, 18 underwent reconstruction with SCAIF (23%), 36 with RFF (47%), and 22 with ALT (29%). Seventy-five laryngopharyngectomies (97%) were performed due to oncologic indications, 27 patients (35%) had been treated with prior radiotherapy. Fifty-seven defects (74%) were partial defects, whereas 20 (26%) were circumferential. RESULTS: No statistical differences in operative time between the groups (298 min ± 53 [SCAIF] vs 301 min ± 54 [ALT] vs 302 min ± 47 [RFF]; P = .806) were observed. Preoperative radiation was found to be an independent risk factor for flap loss (P < .001), the development of fistula (P = .032), and pharyngeal stenosis (P = .034) in our cohort. Nevertheless, no differences between the different groups were detected (fistula rate: 11% [SCAIF] vs 14% [ALT] vs 11% [RFF]; P = .944, stenosis rate: 11% [SCAIF] vs 14% [ALT] vs16% [RFF]; P = .874, gastric tube dependency: 28% [SCAIF] vs 23% [ALT] vs16% [RFF]; P = .590). CONCLUSION: The SCAIF is an equivalent alternative compared to well-established techniques, such as the RFF and the ALT regarding reconstruction of defects after laryngopharyngectomy.

Three Simultaneous Free Flaps to Reconstruct a Complex Frozen Neck and a Large Hypopharyngeal Fistula.

Frozen neck and hypopharyngeal fistula are sometimes present after tumor ablation of the larynx, multiple local surgeries with scar tissue, and radiotherapy and chemotherapy. This multiorgan involvement requires 1 or even 2 flaps. We present a 63-year-old heavy smoker with frozen neck tissue and simultaneous large hypopharyngeal fistula and neck defect. After careful preoperative planning, he was successfully treated with 3 simultaneous free flaps: 2 anterolateral thigh flap (ALT) and 1 lateral arm flap (LAF). One ALT was used as a patch to restore the hypopharynx continuity. A second ALT was used to cover the anterior neck defect and the LAF flap was used to reconstruct the submandibular area. The flaps survived and the patient had a 5 mm proximal fistula which was sutured, and he was able to eat per mouth. By combining multiple free flaps, we were able to restore the function of the hypopharynx and to cover the esthetic units of the neck by avoiding the "turkey neck" appearance.
