Institutional experience with total pharyngectomy reconstruction: Exploring the role of the salivary bypass tube.

BACKGROUND: There is a lack of consensus regarding the effectiveness of salivary bypass tubes during total pharyngectomy reconstruction to prevent pharyngocutaneous fistula or pharyngoesophageal stricture. METHODS: Our study examined tubed free flap reconstruction outcomes for total pharyngectomy defects over 11 years at a single tertiary referral center. We compared postoperative fistula and stricture rates between two groups: those with salivary bypass tubes inserted during reconstruction and those without. RESULTS: Among 36 patients, 26 had radial forearm, and 10 had anterolateral thigh free flap reconstruction. 53% received salivary bypass tubes. However, the tubes did not significantly reduce the relative risks of fistula or stricture. Notably, neck dissection during total pharyngectomy was associated with increased fistula incidence. Minor salivary bypass tube-related complications affected 21% of subjects. CONCLUSION: The role of salivary bypass tubes in total pharyngectomy reconstruction remains uncertain.

Swallowing outcomes over time after total pharyngolaryngectomy and free flap reconstruction.

BACKGROUND: One of the challenges after total pharyngolaryngectomy (TPL) is to restore the swallowing function. The aim of this study was to compare swallowing outcomes between patients who underwent reconstruction with jejunum free flap (JFF) and other free flaps (OFFs). METHODS: This retrospective study included patients who underwent TPL and free flap reconstruction. The endpoints were the evolution of swallowing outcomes during the first five years after treatment assessed by the Functional Oral Intake Scale (FOIS), and outcomes associated with complications. RESULTS: One hundred and eleven patients were included, 84 patients in the JFF group and 27 in the OFF group. The patients in the OFF group experienced more chronic pharyngostoma (p = 0.001) and pharyngoesophageal stricture (p = 0.008). During the first year, a lower FOIS score tended to be associated with OFF (p = 0.137), and this result remained stable over time. CONCLUSIONS: This study suggests that JFF reconstruction provides better swallowing outcomes than OFF reconstruction, stable over time.

Complications of pectoralis major myo-cutaneous flap, anterolateral thigh flap and radial forearm free flap after total laryngectomy with partial pharyngectomy: A systematic review and network meta-analysis.

BACKGROUND: No consensus exists regarding the most effective reconstruction after total laryngectomy with partial pharyngectomy (TLwPP). This study aims to compare different reconstructive techniques (pectoralis major myo-cutaneous flap, PMMCF; anterolateral thigh flap, ALTF; radial forearm free flap, RFFF) after TLwPP in terms of pharyngocutaneous fistula (PCF), stenosis and feeding tube dependence (FTD) incidence. METHODS: The Scopus, PubMed/MEDLINE, Cochrane Library, and Google Scholar databases were searched. A single-arm meta-analysis was performed for PCF incidence, stenosis incidence, and FTD incidence on the entire cohort. An arm-based network analysis was conducted to compare three different surgical interventions (PMMCF, ALTF, RFFF). RESULTS: A total of 13 studies and 232 patients were included in the network meta-analysis. The lowest PCF absolute risk was measured for the RFFF (11.7%, 95% CI: 2.8%-33.4%), compared to the ALTF (13.4%, 95% CI: 4.5%-32.1%) and the PMMC (49.0%, 95% CI: 19.2%-79.3%). The RFFF showed a stenosis absolute risk of 0.0% (95% CI: 0.0%-1.1%), while a higher stenosis incidence was measured for the ALTF (5.7%, 95% CI: 0.8%-25.2%) and the PMMCF (11.6%, 95% CI: 0.8%-55.1%). The RFFF showed the lowest absolute risk of FTD incidence (6.8%, 95% CI: 0.5%-28.1%) compared to the other reconstructive techniques (PMMCF: 12.4%, 95% CI: 2.4%-42.1%; ALTF: 17.5%, 95% CI: 6.4%-38.9%). CONCLUSIONS: The RFFF seems the best choice for reconstruction of partial pharyngeal defects after TLwPP due to the lower incidence of PCF, stenosis and FTD compared to the ALTF and the PMMCF.

Circumferential pharyngeal reconstruction after total laryngopharyngectomy: A systematic review and network meta-analysis.

OBJECTIVE: To compare the functional outcomes of different reconstructive techniques for circumferential pharyngeal reconstruction. METHODS: A comprehensive electronic search was performed on PubMed/MEDLINE, Cochrane Library, and Google Scholar databases. Retrospective and prospective studies were included. Two independent reviewers extracted thirty-four studies after applying the eligibility criteria. An arm-based network analysis was conducted using a Bayesian hierarchical model. The main outcomes were pharyngo-cutaneous fistula (PCF) incidence, stenosis incidence and feeding tube dependence (FTD) incidence. Network estimates from outcome variables were presented as absolute risks, odds ratio [OR] with 95% credible intervals (CIs), and ranking probability. RESULTS: A total of 1357 patients were included for 5 different interventions (tubed pectoralis muscle myocutaneous flap, t-PMMCF; tubed anterolateral tight flap, t-ALTF; tubed radial forearm free flap, t-RFFF; free jejunal flap, FJF; U-shaped pectoralis muscle myocutaneous flap, u-PMMCF). FJF showed a 92.8% chance of ranking first in terms of pharyngo-cutaneous fistula prevention (absolute risk: 10%), while the highest PCF incidence (42%) was measured for t-PMMCF. u-PMMCF showed the lowest absolute risk (11%) of stenosis incidence (62.2% chance of ranking first). t-PMMCF (5%), FJF (8%), and u-PMMCF (8%) showed similar results in terms of feeding tube dependence, with a 53.2%, 23.1% and 18.9% chance of ranking first, respectively. CONCLUSIONS: FJF seems to be the best reconstructive choice after total laryngo-pharyngectomy in terms of PCF, stenosis and FTD incidence. If this reconstructive method is not feasible, a u-PMMCF should be favored over tubed free and pedicled flaps. Further comparative studies are needed to confirm these results.

Phase II Randomized Trial of Transoral Surgery and Low-Dose Intensity Modulated Radiation Therapy in Resectable p16+ Locally Advanced Oropharynx Cancer: An ECOG-ACRIN Cancer Research Group Trial (E3311).

PURPOSE: Definitive or postoperative chemoradiation (CRT) is curative for human papillomavirus-associated (HPV+) oropharynx cancer (OPC) but induces significant toxicity. As a deintensification strategy, we studied primary transoral surgery (TOS) and reduced postoperative radiation therapy (RT) in intermediate-risk HPV+ OPC. METHODS: E3311 is a phase II randomized trial of reduced- or standard-dose postoperative RT for resected stage III-IVa (American Joint Committee on Cancer-seventh edition) HPV+ OPC, determined by pathologic parameters. Primary goals were feasibility of prospective multi-institutional study of TOS for HPV+ OPC, and oncologic efficacy (2-year progression-free survival) of TOS and adjuvant therapy in intermediate-risk patients after resection. TOS plus 50 Gy was considered promising if the lower limit of the exact 90% binomial confidence intervals exceeded 85%. Quality of life and swallowing were measured by functional assessment of cancer therapy-head and neck and MD Anderson Dysphagia Index. RESULTS: Credentialed surgeons performed TOS for 495 patients. Eligible and treated patients were assigned as follows: arm A (low risk, n = 38) enrolled 11%, intermediate risk arms B (50 Gy, n = 100) or C (60 Gy, n = 108) randomly allocated 58%, and arm D (high risk, n = 113) enrolled 31%. With a median 35.2-month follow-up for 359 evaluable (eligible and treated) patients, 2-year progression-free survival Kaplan-Meier estimate is 96.9% (90% CI, 91.9 to 100) for arm A (observation), 94.9% (90% CI, 91.3 to 98.6]) for arm B (50 Gy), 96.0% (90% CI, 92.8 to 99.3) for arm C (60 Gy), and 90.7% (90% CI, 86.2 to 95.4) for arm D (66 Gy plus weekly cisplatin). Treatment arm distribution and oncologic outcome for ineligible or step 2 untreated patients (n = 136) mirrored the 359 evaluable patients. Exploratory comparison of functional assessment of cancer therapy-head and neck total scores between arms B and C is presented. CONCLUSION: Primary TOS and reduced postoperative RT result in outstanding oncologic outcome and favorable functional outcomes in intermediate-risk HPV+ OPC.

Algorithmic Approach Using Negative Pressure Wound Therapy Improved Survival for Patients with Synchronous Hypopharyngeal and Esophageal Cancer Undergoing Pharyngolaryngoesophagectomy with Gastric Tube Reconstruction.

BACKGROUND: This study retrospectively analyzed the feasibility and surgical outcome of an algorithmic approach using negative pressure wound therapy for patients with synchronous hypopharyngeal and esophageal cancer undergoing pharyngolaryngoesophagectomy with gastric tube reconstruction. METHODS: Patients undergoing pharyngolaryngoesophagectomy and gastric tube reconstruction for hypopharyngeal cancer between 2011 and 2019 were candidates for this study. Data were collected on patient demographics, comorbidities, performance status, cancer stage, treatment, complication, and survival. Survival analysis was performed using the Kaplan-Meier method. The Cox proportional hazards model was used for prognostic factors. RESULTS: The study enrolled 43 patients. Anastomotic leakage was found in 21 of the patients with a conventional surgical drain (61.9%) and in 10 of the 22 patients with negative pressure wound therapy (45.5%) (p = 0.280). Nine patients in the conventional drain group (42.9%) and two patients in the negative pressure wound therapy group (9.1%) had leakage-associated complications (p = 0.011). The incidence of pulmonary complications was higher in the conventional surgical drain group (9 vs 2; p = 0.011). The number of complications requiring surgery was higher in the conventional drain group (7 vs 0; p = 0.004). The overall survival in the negative pressure wound therapy group was better (hazard ratio [HR], 0.33; 95% confidence interval [CI], 0.15-0.76; p = 0.009). Negative pressure wound therapy was independently associated with overall survival (HR, 0.31; 95% CI, 0.13-0.77; p = 0.011). CONCLUSIONS: Negative pressure wound therapy with an algorithmic approach improved the overall survival for the patients undergoing gastric tube reconstruction after pharyngolaryngoesophagectomy for hypopharyngeal and esophageal cancer by preventing deadly complications secondary to anastomotic leakage.

Frequent occurrence of postbreakfast syncope due to carotid sinus syndrome after surgery for hypopharyngeal cancer: A case report.

RATIONALE: Syncope often occurs in patients with advanced head and neck cancers due to the stimulation of the autonomic nervous system by the tumor. Here, we describe a case of frequent syncopal episodes after laryngopharyngectomy for hypopharyngeal cancer. As all syncopal episodes were observed during the forenoon, we also evaluated the heart rate variability using ambulatory electrocardiography to determine why the syncopal episodes occurred during a specified period of the day. PATIENT CONCERNS: A 73-year-old Japanese man who underwent laryngopharyngectomy for recurrent hypopharyngeal cancer started experiencing frequent episodes of loss of consciousness that occurred during the same time period (10:00-12:00). He had never experienced syncopal episodes before the operation. From 23 to 41 days postoperatively, he experienced 9 syncopal episodes that occurred regardless of his posture. DIAGNOSES: Pharyngo-esophagoscopy revealed an anastomotic stricture between the free jejunum graft and the upper esophagus. Swallowing videofluoroscopy confirmed the dilatation of the jejunal autograft and a foreign body stuck on the oral side of the anastomosis. Contrast-enhanced computed tomography revealed that the carotid artery was slightly compressed by the edematous free jejunum. The patient was diagnosed with carotid sinus syndrome (CSS) as the free jejunum was dilated when consuming breakfast, which may have caused carotid sinus hypersensitivity and induced a medullary reflex. INTERVENTIONS: Administration of disopyramide was effective in preventing syncope. Heart rate variability analysis using ambulatory electrocardiography showed that parasympathetic dominancy shifted to sympathetic dominancy during 10:00 to 12:00. The significant time regularity of the syncopal episodes may have been affected by modified diurnal variation in autonomic tone activity. OUTCOMES: After the surgical release and re-anastomosis of the pharyngoesophageal stenosis via an open-neck approach, no recurrent episodes of syncope were reported. LESSONS: We reported a case of frequent syncopal episodes limited to the forenoon due to CSS after surgery for hypopharyngeal carcinoma. The patient was treated with anticholinergics followed by the release and re-anastomosis of the pharyngoesophageal stenosis. When syncope occurs after surgery for head and neck lesions, CSS due to postoperative structural changes should be considered as a differential diagnosis of syncope.

Efficacy and Safety of Endoscopic Nasopharyngectomy Combined With Low-Dose Radiotherapy for Primary T1-2 Nasopharyngeal Carcinoma.

AIM: Intensity-modulated radiotherapy (IMRT) is a widely accepted therapy for nasopharyngeal carcinoma (NPC), but it inevitably brings out radiation-related complications and seriously affects the quality of life (QoL). Endoscopic nasopharyngectomy (ENPG) has been successfully conducted in locally recurred NPC, but few studies evaluated its application in early NPC. This study aims to assess the feasibility and safety of ENPG combined with low-dose radiotherapy (LDRT) in T1-2 NPC. PATIENTS AND METHODS: We recruited 37 newly diagnosed localized T1-2 NPC patients who voluntarily accepted ENPG +LDRT from June 2013 to September 2016. Meanwhile, the data of 132 T1-2 NPC patients treated with IMRT were collected and used as control group. The survival outcomes, QoL score and late RT-related sequelaes were compared between the 2 groups. RESULTS: After a median follow-up of 54 months, only 1 patient in ENPG+LDRT group died along with hepatic metastases. The 5-year overall survival, distant metastasis-free survival, local relapse-free survival and regional relapse-free survival in ENPG+LDRT group were 97.3%, 97.3%, 100% and 100%, which were not statistically different from the control group (97.7%, 90.2%, 95. 5%, 97.0%, respectively, all P > 0.05). In comparison with IMRT group, ENPG+LDRT exhibited better QoL and less rate of late RT-related sequlaes including hearing loss (53.8% vs 27.0%, P = 0.005), xerostomia (46.2% vs 24.3%, P = 0.023) and dysphagia (25.8% vs 8.1%, P = 0.024). CONCLUSIONS: ENPG+LDRT provided satisfactory survival outcomes, and improved the QoL and reduced the incidence of sequelae for T1-2 NPC patients.

Free Flap Inset Techniques in Salvage Laryngopharyngectomy Repair: Impact on Fistula Formation and Function.

OBJECTIVE: To characterize pharyngocutaneous fistula (PCF) rates and functional outcomes following microvascular free tissue transfer (MVFTT) reconstruction of salvage total laryngectomy (STL) with a review of two different flap inset techniques and a review of the literature. METHODS: Retrospective review. RESULTS: Review of the literature revealed 887 patients who underwent STL MVFTT from 14 references. Ninety-six STL MVFTTs were performed by the authors, with 36 (38%) patients undergoing multilayer fascial underlay (MLFU) closure and 60 (62%) a standard single layer closure (SLC). One (3%) PCF occurred in the MLFU group compared to 12 (20%) in the SLC cohort (P = .03). Postoperative gastrostomy (G)-tube dependence was lower following MLFU closure compared to SLC (25% vs. 57%, P < .01), whereas pharyngoesophageal stricture (PES) (28% vs. 38%), tracheoesophageal puncture (TEP) placement (42% vs. 42%), and TEP usage (87% vs. 88%) did not significantly differ (P > .05). Compared to pooled rates from the literature, patients who underwent a MLFU MVFTT inset technique demonstrated significantly lower PCF incidence (3% vs. 23%, P < .01) without significant differences in PES (28% vs 23%, P = .55), G-tube dependence (25% vs. 23%, P = .25), or TEP placement (42% vs. 59%, P = .09). CONCLUSION: Despite MVFTT reconstruction after STL, G-tube dependence, PCF formation, and limitations of speaking rehabilitation (TEP) remain a significant issue. Modification of MVFTT inset may provide an opportunity to reduce PCF incidence without affecting other functional outcomes. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E875-E881, 2021.

Risk Factors for Pharyngocutaneous Fistula After Total Pharyngolaryngectomy.

PURPOSE: To evaluate the risk factors of pharyngocutaneous fistula after total pharyngolaryngectomy (TPL) in order to reduce their incidence and propose a perioperative rehabilitation protocol. MATERIALS AND METHODS: This was a multicenter retrospective study based on 456 patients operated for squamous cell carcinoma by total laryngectomy or TPL. Sociodemographic, medical, surgical, carcinologic, and biological risk factors were studied. Reactive C protein was evaluated on post-op day 5. Patients were divided into a learning population and a validation population with patients who underwent surgery between 2006 and 2013 and between 2014 and 2016, respectively. A risk score of occurrence of salivary fistula was developed from the learning population data and then applied on the validation population (temporal validation). OBJECTIVE: To use a preoperative risk score in order to modify practices and reduce the incidence of pharyngocutaneous fistula. RESULTS: Four hundred fifty-six patients were included, 328 in the learning population and 128 in the validation population. The combination of active smoking over 20 pack-years, a history of cervical radiotherapy, mucosal closure in separate stitches instead of running sutures, and the placement of a pedicle flap instead of a free flap led to a maximum risk of post-op pharyngocutaneous fistula after TPL. The risk score was discriminant with an area under the receiver operating characteristic curve of 0.66 (95% confidence interval [CI] = 0.59-0.73) and 0.70 (95% CI = 0.60-0.81) for the learning population and the validation population, respectively. CONCLUSION: A preoperative risk score could be used to reduce the rate of pharyngocutaneous fistula after TPL by removing 1 or more of the 4 identified risk factors.

Speech Performance after Anterolateral Thigh Phonatory Tube Reconstruction for Total Laryngectomy.

OBJECTIVE: Traditionally, after total laryngopharyngectomy (TLP), patients cannot speak without a prosthesis or an artificial larynx. In Taiwan, most patients use a commercialized pneumatic laryngeal device (PLD). Phonatory tube reconstruction with the anterolateral thigh (ALT) flap is a novel, modified version of synchronous digestive and phonatory reconstruction involving a free muscular cutaneous flap. This study reviewed and compared speech performance between patients who underwent novel flap reconstruction and conventional PLD users. METHOD: We retrospectively reviewed patients with laryngeal or hypopharyngeal cancer who underwent TLP from August 2017 to September 2019. The voice handicap index (VHI), speech intelligibility, acoustic and aerodynamic analysis results, and speech range profile (SRP) were compared between patients who underwent ALT phonatory tube reconstruction (ALT group) and those using PLDs (PLD group). RESULTS: Twenty patients were included; 13 patients were included in the ALT group, and 7 patients were included in the PLD group. Compared to the PLD group, the ALT group had a better fundamental frequency range (P < .001) and semitone range (P < .001) during speech but showed worse jitter, shimmer, and harmonic-to-noise ratios. The two groups showed comparable VHI and speech intelligibility performance. CONCLUSIONS: The ALT phonatory tube, a novel flap for reconstruction, can restore digestive and voice functions simultaneously. Compared with PLD use, ALT phonatory tube reconstruction yields an improved speech range and comparable levels of voice handicap and speech intelligibility, suggesting that the technique is a good alternative for patients after TLP. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:1349-1357, 2021.

Pharyngeal reconstruction with a modified free alt flap with parastomal fascial wings.

AIM: Previous reports have demonstrated good outcomes with the use of the Anterolateral Thigh Flap (ALT) in pharyngeal reconstruction. We report a new modification of free ALT flap pharyngeal reconstruction utilizing vascularised fascial wings or extensions placed in the parastomal gutters to cover the major neck vessels. PATIENTS AND METHODS: This was a single-center retrospective case review. Between November 2017 and January 2019, 8 patients (6 male, 2 female mean age 61, range 35 to 74) underwent near circumferential pharyngeal reconstruction by the modified technique. 3 patients had laryngopharyngectomy for radiorecurrent larynx SCC, 2 for primary, advanced laryngeal SCC, and 3 for primary hypopharyngeal SCC. RESULTS: All eight patients regained adequate swallow to maintain nutrition without tube-feeding. Two of the patients have been assessed as appropriate for tracheo-esophageal puncture and are awaiting placement. One patient uses an electrolarynx for speech and 5 patients aphonic only. One patient died 2 months after the procedure from chest infection. There were no flap failures, no fistulas and no strictures at one year. One patient who underwent a salvage laryngopharyngectomy experienced parastomal wound dehiscence, but critically there was no return to theater for exposed major vessels and the wound healed within 6 weeks requiring dressings only. CONCLUSION: Here we report outcomes of pharyngeal reconstruction with a modified single perforator free ALT flap using fascial extensions to line the parastomal gutters. In the event of parastomal dehiscence, the placement of vascularized tissue parastomally may facilitate spontaneous healing and prevent major vessel exposure.

Hypoalbuminemia-Related Prolonged Sedation After General Anesthesia: A Case Report.

A 69-year-old man underwent total laryngopharyngectomy with radial forearm free flap reconstruction. He had lost 15 kg over a period of 6 months and did not receive any preoperative nutritional workup or management. The patient had a general total intravenous anesthetic with ketamine, lidocaine, and propofol, which was uneventful for an 8-hour surgery. The patient remained deeply sedated for 4 hours after discontinuation of all sedative medications. Diagnostic workup only revealed hypoalbuminemia and hypoproteinemia. We hypothesized relative overdosage of sedative anesthetic drugs due to preoperative malnutrition accentuated by intraoperative fluid administration.

Pharyngeal reconstruction using a U-shaped pectoralis major myocutaneous flap: an effective technique that should not be forgotten.

INTRODUCTION: Although free tissue transfer is thought the best option for head and neck reconstruction, the pectoralis major myocutaneous flap (PMMCF) remains an important alternative method. The aim of this study was to assess the use of the PMMCF with the prevertebral fascia to close a pharyngeal defect. MATERIALS AND METHODS: This was a retrospective study of 30 patients who underwent circumferential pharyngeal defect reconstruction with a U-shaped PMMCF from 2009 to 2018. The flap was primarily used to reconstruct defects after tumor extirpation. RESULTS: One patient (3.3%) died of an acute myocardial infarction within 24 h of the operation. Six cases (20.0%) developed a pharyngocutaneous fistula; one of them required debridement, while the others spontaneously healed with conservative treatment. Seven cases (23.3%) developed tracheal stomal stenosis. Twenty-four (80.0%) of these cases could eat a regular diet, while the other five cases needed tube feeding. CONCLUSION: In patients with late-stage laryngopharyngeal cancer, reconstructing circumferential pharyngeal defects with the U-shaped PMMCF is an expedient alternative to free tissue transfer.

Predictors and Prevalence of Nodal Disease in Salvage Oropharyngectomy.

BACKGROUND: Patients with recurrent oropharyngeal cancer often require extensive salvage surgery. For patients with clinically N0 necks, the indication for concurrent neck dissection remains unclear. This study aimed to determine predictors, prevalence, and distribution of nodal disease in patients treated with salvage oropharyngectomy. METHODS: In a case series with data collection at a single tertiary academic National Cancer Institute (NCI)-designated comprehensive cancer center, this study analyzed patients treated with prior radiation or chemoradiation who had persistent, recurrent, or second primary squamous cell carcinoma of the oropharynx requiring oropharyngeal resection between 1998 and 2017 (n = 95). Clinical and oncologic characteristics and treatment outcomes were collected, and statistical analyses were performed. RESULTS: The overall rate of nodal positivity was 21% (24/95), and the rate of occult nodal disease was 6% (4/65). Ipsilateral and contralateral level 2 were the most common areas harboring positive nodes. Bivariate analysis showed female sex (p = 0.01), initial overall stage (p = 0.02), and N status (p = 0.03), as well as recurrent overall and T stage (p = 0.05) to be predictors of nodal disease. In the multivariate analysis, recurrent T stage continued to be significantly predictive of pathologic nodal disease. Both computed tomography (CT) and positron emission tomography-CT were moderately accurate in predicting nodal disease in the salvage setting (area under the curve, 0.79 and 0.80, respectively). CONCLUSION: Occult nodal disease is observed in few patients undergoing salvage oropharyngeal resection. This study identified factors predictive of nodal disease in patients undergoing salvage oropharyngectomy and appropriate diagnostic tests in this setting.

Impact of internal mammary artery perforator propeller flap in neck resurfacing and fistula closure after salvage larynx cancer surgery: Our experience.

BACKGROUND: Salvage total laryngectomy (TL) and laryngopharyngectomy (LP) after chemoradiotherapy may produce disfiguring defects with severe complications that require complex reconstructions. METHODS: Between January 2012 and December 2018, we enrolled 25 patients who underwent internal mammary artery perforator (IMAP) flap reconstruction after salvage TL or LP. We performed retrospective review of clinical charts to collect information such as history, timing of reconstruction, type of defect, follow-up, donor and recipient site complications, and overall flap survival (OFS) rate. Three years overall survival (OS), relapse-free survival (RFS), and disease-specific survival (DSS) were calculated. RESULTS: The OFS rate was 95%. One partial flap necrosis was recorded. No donor-site complications were found. The mean follow-up was 18 months. Three years OS was 44%, RFS was 47%, and DSS was 54%. CONCLUSIONS: IMAP flap appears to be safe, versatile, and easy to harvest, with minimal donor site morbidity. It is a reliable option in Head&Neck reconstruction, in salvage surgery as well.

Total laryngopharyngectomy with circumferential reconstruction: Helsinki institutional study.

PURPOSE: Surgical complications after total laryngopharyngectomy (TLP) are common, reconstruction is challenging, and patients often lose their ability to swallow and speak. To evaluate these aspects, we analysed outcome after TLP. METHODS: We reviewed all patients who underwent TLP and subsequent circumferential pharyngeal reconstruction through 2004-2017 at the Helsinki University Hospital. RESULTS: For the 26 eligible patients, TLP was the primary treatment for 11 and salvage surgery for 15, followed by reconstruction with free flaps in 22 patients and pedicled flaps in 4. An early (≤ 30 days) pharyngocutaneous fistula developed in seven patients (27%; median time 13 days; range 6-26), and a late (> 30 days) fistula in five patients (19%; median time 370 days; range 46-785). In addition, ten patients (39%) developed an oesophageal stricture. Four patients (15%) resumed full oral feeding. A speech prosthesis was inserted for 15 patients (58%) and most of them could produce intelligible speech. We found acceptable survival figures for patients undergoing TLP both as a primary treatment and as salvage procedure: the overall survival at 1 year was 82% and 67%, and at 5 years 33% and 27%, respectively. Disease-specific survival at 1 year was 90% and 70%, and that at 5 years was 45% and 43%, respectively. CONCLUSIONS: Despite fair survival, TLP carries a high risk for postoperative complications with limited functional outcome, thus necessitating cautious patient selection and surgical experience.

Clinical and functional outcomes after total laryngectomy and laryngopharyngectomy: Analysis by tumor subsite, salvage status, and extent of resection.

BACKGROUND: Outcomes following surgical intervention for laryngeal and hypopharyngeal tumors are dependent on several factors. In the present study, we sought to determine whether tumor subsite, salvage status, and extent of resection influenced postoperative outcomes. METHODS: Retrospective review of 107 patients at a single institution who underwent total laryngectomy or partial/total laryngopharyngectomy. RESULTS: Hypopharyngeal subsite and total laryngopharyngectomy subgroups had inferior speech and swallow outcomes compared to their respective cohorts (P < .05). Salvage patients had inferior 3-year overall survival (P < .05) and swallow outcomes (P < .001). Previously radiated patients had increased fistula rates (29.9% vs 10%, P = .02), and the use of tissue coverage in salvage total laryngectomy had a protective effect on fistula formation (10% vs 37%, P = .04). CONCLUSIONS: By stratifying patients across multiple subgroups, we provide a detailed narrative in surgical outcomes that can be incorporated into treatment planning. Further prospective studies are needed to compare surgical outcomes to those of organ preservation therapy.
