The impact of previous endoscopic treatments on functional outcome after cricotracheal resection.

OBJECTIVES: Treatment options for benign subglottic stenosis include endoscopic techniques or open surgery. Although endoscopic treatment is less invasive, a considerable proportion of patients develop recurrent stenosis. Endoscopic pretreatments do not exclude patients from a later surgical repair; however, the impact of previous endoscopic treatment attempts on functional outcome after open surgery is unknown. METHODS: All patients, who received a cricotracheal resection (CTR) between January 2017 and June 2023 at the Department of Thoracic Surgery, Medical University of Vienna, were included in this retrospective study. Patient characteristics, surgical variables and postoperative outcome including a detailed functional assessment were analysed. RESULTS: A total of 65 patients received a CTR during the study period, of which 40 were treatment naïve and 25 had a median of 2 (range 1-9) endoscopic pretreatments. Less-invasive voice-sparing CTR or standard CTR were more often possible in treatment-naïve patients. In contrary, pretreated patients regularly required extended procedures (P = 0.049). Three or more endoscopic treatments resulted in a significantly lower mean fundamental frequency (F0) after open repair (P = 0.048). In addition, a trend towards smaller mean sound pressure levels, a higher voice handicap index, higher impairments in RBH scores (roughness, breathing and hoarseness) and a higher dysphagia severity index was found in pretreated patients. The respiratory outcome after surgery was comparable between both groups. CONCLUSIONS: Multiple endoscopic pretreatments lead to worse voice quality after CTR. The impact of prior endoscopic treatment before surgical repair should be considered when discussing treatment options with patients suffering from subglottic stenosis.

In-depth analysis of pre- and postoperative functional outcome parameters in patients receiving laryngotracheal surgery.

OBJECTIVES: Surgical treatment for airway stenosis necessitates personalized techniques based on the stenosis location and length, leading to favourable surgical outcomes. However, there is limited literature on functional outcomes following laryngotracheal surgery with an adequate number of patients. METHODS: We conducted a retrospective analysis of patients who underwent laryngotracheal surgery at the Department of Thoracic Surgery, Medical University of Vienna, from January 2017 to June 2021. The study included standardized functional assessments before and after surgery, encompassing spirometry, voice measurements, swallowing evaluation and subjective patient perception. RESULTS: The study comprised 45 patients with an average age of 51.9 ± 15.9 years, of whom 89% were female, with idiopathic being the most common aetiology (67%). Procedures included standard cricotracheal resection in 11%, cricotracheal resection with dorsal mucosal flap in 49%, cricotracheal resection with dorsal mucosal flap and lateral cricoplasty in 24% and single-stage laryngotracheal reconstruction in 16%. There were no in-hospital mortalities or restenosis cases during the mean follow-up period of 20.8 ± 13.2 months. Swallowing function remained intact in all patients. Voice evaluations showed a decrease in fundamental vocal pitch [203 (81-290) Hz vs 150 (73-364) Hz, P < 0.001] and dynamic voice range (23.5 ± 5.8 semitones vs 17.8 ± 6.7 semitones, P < 0.001). However, no differences in voice volume were observed (60.0 ± 4.1 dB vs 60.2 ± 4.8 dB, P = 0.788). The overall predicted voice profile changed from R0B0H0 to R1B0H1. CONCLUSIONS: Laryngotracheal surgery proves effective in fully restoring breathing capacity while preserving vocal function. Even in cases of high-grade and complex airway stenosis necessitating laryngotracheal reconstruction, favourable functional outcomes can be achieved.

A novel technique of voice-sparing cricotracheal resection.

Background: Cricotracheal resection (CTR) is considered the standard of care for patients suffering from idiopathic subglottic stenosis (iSGS). Although CTR results in permanent restoration of airway patency, it has a mild to moderate impact on voice quality. Here we propose modifications of the standard CTR technique to make it a voice-preserving procedure. Methods: Five women with iSGS underwent voice-sparing CTR between January 2022 and January 2023. In this procedure, through several technical adaptations, the function of the cricothyroid joint was preserved. Outcomes of these voice-sparing CTRs were compared to outcomes in patients who underwent standard CTR in our institution. All patients underwent full functional preoperative and postoperative workups, including spirometry, voice measurements, patient self-assessment, and fiberoptic endoscopic evaluation of swallowing. Results: All 5 patients in the study group suffered from iSGS with high-grade Myer-Cotton III° stenosis (100%); 1 patient had previously undergone endoscopic laser resection. Voice evaluation demonstrated a nearly unchanged fundamental pitch (mean preoperative, 191 ± 73.1 Hz; postoperative, 182 ± 64.2 Hz) and dynamic voice range (preoperative, 24.4 semitones; postoperative, 20.4 semitones). This was in contrast to the control group, in which significantly reduced voice quality was observed. Conclusions: In selected patients suffering from iSGS, excellent functional results can be obtained with voice-sparing CTR.

[S1 guidelines for the management of postviral conditions using the example of post-COVID-19]. / Leitlinie S1 für das Management postviraler Zustände am Beispiel Post-COVID-19.

These S1 guidelines are an updated and expanded version of the S1 guidelines on long COVID differential diagnostic and management strategies. They summarize the state of knowledge on postviral conditions like long/post COVID at the time of writing. Due to the dynamic nature of knowledge development, they are intended to be "living guidelines". The focus is on practical applicability at the level of primary care, which is understood to be the appropriate place for initial access and for primary care and treatment. The guidelines provide recommendations on the course of treatment, differential diagnostics of the most common symptoms that can result from infections like with SARS-CoV-2, treatment options, patient management and care, reintegration and rehabilitation. The guidelines have been developed through an interdisciplinary and interprofessional process and provide recommendations on interfaces and possibilities for collaboration.

[Paediatric Airway Surgery - Indications and Techniques]. / Pädiatrische Atemwegschirurgie: Indikationen und Techniken.

Even in specialised centres, surgical procedures on the airway are only rarely performed in paediatric patients. Moreover, knowledge of various specific anatomical characteristics, diseases and surgical techniques is a prerequisite to treat these patients. Most commonly, sequelae of long-term intubation or tracheostomy in multimorbid patients necessitate surgical repair. Moreover, congenital malformations of the airways might require surgical interventions. However, these are commonly associated with other organ malformations, which adds further complexity to the treatment concept. Thus, cooperation within an interdisciplinary team is absolutely necessary to treat these patients. However, good postoperative outcomes after paediatric airway surgery can be achieved in experienced centres with an appropriate infrastructure. Specifically, this means long-term tracheostomy-free survival with preserved laryngeal functions in most of the patients. This review provides a summary of common indications and surgical techniques in paediatric airway surgery.

Position Statement of the Union of European Phoniatricians (UEP): Fees and Phoniatricians' Role in Multidisciplinary and Multiprofessional Dysphagia Management Team.

The need for multidisciplinary and multiprofessional management of dysphagia is constantly increasing and creating a major challenge for healthcare professionals and society, especially in terms of professional expertise and human resources. The distribution of tasks among the dysphagia team members, which includes phoniatricians, otolaryngologists, and speech-language therapists, is flexible and overlapping. For assessing dysphagia, the (fibreoptic) flexible endoscopic evaluation of swallowing (FEES), with or without videofluoroscopy, is a pivotal diagnostic tool. This position paper aims to illustrate the phoniatrician's role in performing a FEES, which is an indispensable component of the diagnostic workup of patients suffering from oropharyngeal dysphagia. It is based on the current collaborative expert view of the Swallowing Committee of the Union of European Phoniatricians and a literature review. A FEES is one of the core competences of phoniatricians due to their endoscopic expertise and experience in the field of dysphagia and diseases of the upper aerodigestive tract. Therefore, the phoniatrician is an important member of the dysphagia team, for the medical diagnostics of the aerodigestive tract and dysphagia as well as for FEES. Phoniatric competence is especially important for head and neck cancer patients, infants, and complex cases.

Long-Term Swallowing Outcome and Dysphagia in Advanced Staged Head and Neck Squamous Cell Carcinomas after Radiotherapy.

Objective: To evaluate the impact of radiotherapy (RT) on dysphagia and long-term swallowing outcome in patients with stage III and IV head and neck squamous cell carcinomas (HNSCCs). Material and Methods: Between 2005 and 2008, 189 patients with HNSCCs underwent primary or adjuvant RT in a curative setting. Long-term swallowing outcome was evaluated in 50 patients. Among them, 26 were further eligible for prospective analysis of long-term swallowing and dysphagia outcome. Medical charts were retrospectively reviewed regarding pre- and post-treatment dysphagia (3 months after last irradiation setting) as well as persisting long-term dysphagia (2019−2021). Results: Pre-treatment dysphagia was observed in 24 (48%) of 50 patients, particularly in oropharyngeal or hypopharyngeal stage III−IV tumors (OR 9.3; p = 0.003). Conversely, 46 patients (92%) complained about post-treatment dysphagic symptoms, which were more commonly seen in patients with positive neck nodes (OR 10.5; p = 0.037). The post-treatment dysphagia rate dropped from 92% to 24% (p < 0.001) during surveillance, which was significantly linked to xerostomia (OR 5.77; p = 0.019), dysgeusia (OR 9.9; p = 0.036) and free flap reconstruction (OR 6.1; p = 0.022). Conclusion: Pretreatment dysphagia is common in advanced stage HNSCCs and almost all patients complain about dysphagia at the end of RT. Importantly, applied RT protocols did not affect long-term dysphagia, which improves significantly in the majority of patients over time. Meeting Information: Preliminary results have been presented at the 65th Annual Meeting of the Austrian Society of Otorhinolaryngology, 22−26 September 2021, Austria.

Cervical Repair of Iatrogenic Tracheobronchial Injury by Tracheal T-Incision.

BACKGROUND: Tracheobronchial injury is a rare but potentially life-threatening condition. Various surgical treatment options have been described for symptomatic patients with full-thickness injury. However, studies comprising a meaningful number of patients are sparse. METHODS: We retrospectively analyzed all patients who received surgical repair of tracheobronchial injury between January 1999 and May 2021 at the Department of Thoracic Surgery, Medical University of Vienna. Patient characteristics, surgical variables, postoperative morbidity, and mortality were retrieved and analyzed. RESULTS: Fifty patients with a median age of 68 years (range, 17-88) were included in the analysis. The etiologies of the iatrogenic tracheobronchial injuries were emergency intubation (48%), elective percutaneous dilatation tracheostomy (38%), or elective intubation (14%). The most common location of tracheobronchial injuries was distal third (28%) with a median length of 50 mm (range, 20-100 mm). The surgical approach was cervicotomy in 52%, thoracotomy in 38%, sternotomy in 2%, and combined approaches in 8% of cases. Moreover, intraoperative venovenous (n = 4) or venoarterial (n = 2) extracorporeal membrane oxygenation support was required in 12% of cases. Procedure-related mortality was 0%. However, as patients with tracheobronchial injury usually have severe comorbidities, the rate of patients discharged alive from the intensive care unit was only 66%. The median follow-up period of discharged patients was 5.5 months (range, 0.7-209). Airway stenosis or dehiscence was not observed in any patient. CONCLUSIONS: Surgical repair of tracheobronchial injuries can be performed safely with a low procedure-related morbidity. If possible, the less-invasive cervical access should be preferred for patients with tracheobronchial injury, even for injuries extending to the main bronchi.

Functional outcome after single-stage laryngotracheal reconstruction with rib cartilage grafting.

OBJECTIVE: Single-stage laryngotracheal reconstruction (SSLTR) provides a definite surgical treatment for patients with complex glotto-subglottic stenosis. To date, the influence of SSLTR on the functional outcome after surgery has not been analyzed. METHODS: A retrospective analysis of all patients receiving a SSLTR between November 2012 and October 2019 was performed. Preoperatively and 3 months postoperatively, patients received a full functional evaluation, including spirometry; voice measurements (eg, fundamental frequency; dynamic range, singing voice range, and perceptual voice evaluation using the Roughness-Breathiness-Hoarseness [RBH] score, and fiberoptic endoscopic evaluation of swallowing [FEES]). RESULTS: A total of 15 patients with a mean age of 45 ± 17 years underwent SSTLR. Two (13%) patients were men and 13 (87%) were women. The majority of patients (67%) had undergone previous surgical or endoscopic treatment attempts that had failed. At the 3-month follow-up visit, none of the patients had signs of penetration or aspiration in their swallowing examination. Voice measurements revealed a significantly lower fundamental voice frequency (201.0 Hz vs 155.5 Hz; P = .006), whereas voice range (19.1 semitones vs 14.9 semitones; P = .200) and dynamic range (52.5 dB vs 53.0 dB; P = .777) was hardly affected. The median RBH score changed from R1 B0 H1 to R2 B1 H2. In spirometry, breathing capacity increased significantly (peak expiratory flow, 44% vs 87% [P < .001] and mean expiratory flow at 75% of vital capacity, 48% vs 90% [P < .001]). During a median follow-up of 32.5 months (range, 7-88 months), none of the patients developed re-stenosis. CONCLUSIONS: For complex glotto-subglottic stenoses, durable long-term airway patency together with reasonable voice quality and normal deglutition can be achieved by SSLTR.

[Guideline S1: Long COVID: Diagnostics and treatment strategies]. / Leitlinie S1: Long COVID: Differenzialdiagnostik und Behandlungsstrategien.

This guideline comprises the state of science at the time of the editorial deadline. In view of the high turnover of knowledge the guideline is designed as a living guideline. The main objective was to provide a tool for the use in primary care, being considered well suited as a first point of entry and for the provision of care. The guideline gives recommendations on the differential diagnosis of symptoms following SARS-CoV­2 infection, on their therapeutic options, as well as for guidance and care of the patients concerned. It also offers advice concerning return to daily life and rehabilitation. Long COVID being a very variable condition, we chose an interdisciplinary approach.

Laryngotracheal resection can be performed safely without a guardian Chin stitch-a single-centre experience including 165 consecutive patients.

OBJECTIVES: A tension-free anastomosis is crucial to minimize the risk of airway complications after laryngotracheal surgery. The 'guardian' chin stitch is placed to prevent hyperextension of the neck in the early postoperative period. This manoeuvre was introduced early in tracheal surgery and is now routinely performed by many airway surgeons. However, the evidence for or against is sparse. METHODS: We performed a retrospective analysis of all adult patients receiving a (laryngo-)tracheal resection at our department from October 2011 to December 2019. According to our institutional standard, none of the patients received a chin stitch. Instead, a head cradle was used to obtain anteflexion of the neck during the first 3 days and patients were instructed to avoid hyperextension of the neck during the hospital stay. The postoperative outcome and the rate of anastomotic complications were analysed. RESULTS: A total of 165 consecutive patients were included in this study. Median age at surgery was 53 years (18-80). Seventy-four patients received a tracheal resection, 24 a cricotracheal resection, 52 an extended cricotracheal resection including dorsal mucosectomy and 15 a single-stage laryngotracheal reconstruction. The median resection length was 25 mm (range 10-55 mm). One hundred and sixty-two out of 165 (98.2%) patients had an unremarkable postoperative course. One patient (0.6%) had partial anastomotic rupture after a traumatic reintubation, which required revision surgery and re-anastomosis. Two patients (1.2%) after previous radiation therapy (>60 Gy) developed a partial necrosis of the anastomosis, resulting in prolonged airleak and fistulation. At follow-up, bronchoscopy 3 months after surgery, 92.7% (127/137) of the patients had a proper anastomosis, 6.6% (9/137) had minor granuloma formations at the site of the anastomosis, which were all treated successfully by endoscopic removal. One patient received dilatation for restenosis (0.7%). CONCLUSIONS: After sufficient mobilization of the central airways, postoperative anteflexion of the neck supported by a head cradle is sufficient to prevent excessive anastomotic tension and dehiscence. Considering the risk for severe neurological complications associated with the chin stitch, the routine use of this manoeuvre in laryngotracheal surgery should not be recommended.

Diagnostic limitation of laryngostroboscopy in comparison to laryngeal electromyography in synkinesis in unilateral vocal fold paralysis.

PURPOSE: In clinical practice, laryngo(strobo)scopy (LS) is still mainly used for diagnostics and management of unilateral vocal fold paralysis (UFVP), although only laryngeal electromyography (LEMG) can provide information on causes of vocal fold immobility, especially on possible synkinetic reinnervation after recurrent laryngeal nerve (RLN) injury. The goal of this retrospective study was the evaluation whether signs of synkinetic reinnervation in LS can be objectified in comparison to LEMG data. METHODS: Between 1/2015 and 2/2018, 50 patients with laryngostroboscopically suspected UVFP received routine LEMG examination. The LEMG findings were retrospectively compared with LS findings. The LEMG data analysis focused on the diagnosis of synkinetic reinnervation of the TA/LCA and/or PCA. The digital LS recordings were retrospectively re-evaluated by phoniatricians considering 22 selected laryngostroboscopic parameters. RESULTS: LEMG revealed synkinesis in 23 (46%) and absence of synkinesis in 27 (54%) patients. None of the 22 parameters showed significant association between patients with synkinetic reinnervation and LS findings. The only laryngostroboscopic parameter that was significantly associated with a silent LEMG signal compared to single fiber activity in LEMG was a length difference on the side of the UVFP (p-value 0.0001; OR 14.5 (95% CI 3.047-66.81; Sensitivity 0.5; Specificity 0.9355). CONCLUSION: Our findings show that synkinesis cannot be diagnosed using only LS. This study underlines the importance of LEMG in clinical routine for detection of laryngeal synkinesis in patients with UVFP before any further therapeutic steps are initiated to avoid later therapy failure.

Comparison of voice therapy and selective electrical stimulation of the larynx in early unilateral vocal fold paralysis after thyroid surgery: A retrospective data analysis.

OBJECTIVES: The goal of the retrospective study was to investigate the 3-month-outcome after treatment of patients with early unilateral vocal fold paralysis (UVFP) with either standard voice therapy (VT) or selective electrical stimulation of the larynx (SES). DESIGN: Non-randomised retrospective study. SETTING: 1519 patients who underwent thyroid surgery between 2015 and 2018 were analysed according vocal fold mobility; UVFP patients were treated either by VT or SES. PARTICIPANTS: 51 UVFP patients. MAIN OUTCOME MEASURES: 51 UVFP patients have been advised regarding treatment options like either VT (group 1) or SES (group 2). The patients of group 1 (n = 26) and 2 (n = 25) were re-assessed up to 3 months post-operatively regarding UVFP persistence/recovery and perceptive voice sound quality. At follow-ups, perceptual analysis of voice sound (using roughness=R/breathiness=B/hoarseness=H scale) and endoscopic laryngoscopy have been performed. Position of immobile vocal fold, shape of glottal closure and RBH parameters have been considered for statistical analyses. RESULTS: Restitution of UVFP with regular respiratory vocal fold mobility of both vocal folds occurred in 53.8% of group 1 (VT), and in 40.0% of group 2 (SES) after 3 months of therapy between both groups. No difference could be seen for RBH, type of glottal closure and position of ailing vocal folds in patients with persisting UVFP within both groups and between the groups. CONCLUSIONS: The study reveals that SES can achieve similar functional outcome in early UVFP. Thus, it should be considered as an equivalent therapy alternative to VT for treatment of early UVFP patients since no significant difference in vocal outcome and glottal configuration between the two groups could be demonstrated.

Laryngeal Mask as the Primary Airway Device During Laryngotracheal Surgery: Data From 108 Patients.

BACKGROUND: Airway management during repair of laryngotracheal stenosis is demanding, and there is currently no accepted standard of care. Recently an increasing number of airway centers have started to use a laryngeal mask until the airway is surgically exposed and cross-table ventilation can be initiated. However detailed data on this approach are missing in the literature. METHODS: Patients receiving laryngotracheal surgery from November 2011 until October 2018 were retrospectively included in this single-center study, except for patients who presented with a preexisting tracheostomy at time of surgery. Airway management uniformly consisted of laryngeal mask ventilation until cross-table ventilation was established. Clinical variables, perioperative complications, and airway complications were analyzed. RESULTS: One hundred eight patients (65 women, 43 men) receiving tracheal resection (n = 50), cricotracheal resection (n = 49), or single-stage laryngotracheal reconstruction (n = 9) were included in the analysis. Of the included patients 23 (21.3%) had malignant disease and 85 (78.7%) a benign pathology. In the subgroup of patients with subglottic disease 85.1% had high-grade stenosis (Myer-Cotton III°). Airway management with a laryngeal mask was successful in all except 1 patient (99.1%). Mean pulse oximetry and mean end-tidal CO2 during laryngeal mask ventilation was 98.7% ± 2.4% and 34.8 ± 7.6 mm Hg, respectively. At the end of surgery 95 patients (88%) were successfully weaned from the respirator using the laryngeal mask. CONCLUSIONS: The laryngeal mask as the primary airway device is feasible and safe in patients undergoing laryngotracheal surgery even in cases with high-grade stenosis.

Established and innovative surgical techniques for the treatment of benign subglottic stenosis.

Surgical treatment of benign subglottic stenoses can be challenging. It requires the close cooperation of an experienced team that includes various specialist disciplines. The treatment success will be evaluated with an extensive documentation of voice quality, lung function and swallowing function. The stenosis has to be analyzed in terms of its etiology, severity and pretreatment. Endoscopic removal of the stenotic tissue often leads to good short-term results. However, the proportion of re-stenoses is very high, which are often even more severe. Long-term treatment success can often only be achieved by surgical resection. The surgical technique used must be strictly adapted to the individual stenosis. In principle, a distinction can be made between classic cricotracheal resections and those that receive an expanded operative component. Particularly in the case of high-grade side-to-side stenoses, complex reconstruction with cartilage graft may be necessary. It is important not just to restore the airway flow. Maintaining the vocal function is an equally important treatment goal. Experienced centers can achieve very satisfactory long-term results with regard to functional outcome and voice quality.

Functional evaluation before and after laryngo-tracheal resection.

Laryngotracheal resections have become a clinical routine in experienced airway centers and even extended glotto-subglottic resections and reconstructions can be performed with low complication rates and excellent long-term airway patency. However, reports on the functional outcome after laryngotracheal resections are sparse and there is no general agreement among airway surgeons, which functional evaluations should be performed before and after surgery. The following review provides an overview on basic assessment tools, which can be used to objectively report functional outcome after laryngotracheal surgery.

Pre- and intraoperative acoustic and functional assessment of the novel APrevent® VOIS implant during routine medialization thyroplasty.

PURPOSE: Persistent unilateral vocal fold paralysis (UFVP) with glottal insufficiency often requires type I medialization thyroplasty (MT). Previous implants cannot be adjusted postoperatively if necessary. The newly developed APrevent® VOIS implant (VOIS) can provide postoperative re-adjustment to avoid revision MT. The objective of this pilot study is to evaluate the VOIS intraoperatively concerning voice improvement, surgical feasibility and device handling. METHODS: During routine MT, VOIS was applied short time in eight patients before the regular implantation of the Titanium Vocal Fold Medialization Implant (TVFMI™). In all patients, perceptual voice sound analysis using R(oughness)-B(reathiness)-H(oarseness)-scale, measurement of M(aximum)-P(honation)-T(ime) and glottal closure in videolaryngoscopy were performed before and after implanting VOIS/TVFMI™. Acoustic analyses of voice recordings were performed using freeware praat. Surgical feasibility, operative handling and device fitting of VOIS and TVFMI™ were assessed by the surgeon using V(isual)-A(nalog)-S(cale). Data were statistically analyzed with paired t test. RESULT: All patients showed significant improvement of voice sound parameters after VOIS/TVFMI™ implantation. The mean RBH-scale improved from preoperative R = 2.1, B = 2.3, H = 2.5 to R = 0.6, B = 0.3, H = 0.8 after VOIS and R = 0.5, B = 0.3, H = 0.8 after TVFMI™ implantation. The mean MPT increased from preoperative 7.9 to 14.6 s after VOIS and 13.8 s after TVFMI™ implantation. VOIS/TVFMI™ achieved complete glottal closure in 7/8 patients. The satisfaction with intraoperative device fitting and device handling of VOIS was as good as that of TVFMI™. CONCLUSION: The novel APrevent® VOIS implant showed similar intraoperative voice improvement compared to routinely used TVFMI™ without adverse device events and with safe device fitting.

Use of the myocutaneous serratus anterior free flap for reconstruction after salvage glossectomy.

PURPOSE: To describe the use of a myocutaneous serratus anterior free flap (SAFF) for tongue reconstruction after salvage subtotal (STG) and total glossectomy (TG). METHODS: In this prospective case series, seven patients underwent salvage STG or TG and reconstruction with a myocutaneous SAFF between 10/2015 and 02/2017. Functional and oncologic outcomes were prospectively evaluated. Donor side morbidity was determined using the Disabilities of the Arm, Shoulder and Hand (DASH) score. RESULTS: SAFF with mean skin paddles of 6.7 cm × 8.7 cm was used in five STG and two TG patients, respectively. There was a 100% flap survival and a mean DASH score of 10.8 reflected normal arm and shoulder function after surgery. One year after salvage surgery, 1 (14.3%) and 4 (57.1%) patients were tracheostomy and gastrostomy tube dependent. Gastrostomy tube dependence was significantly worse in patients with tumors of the base of tongue compared to other tumor sites (p = 0.030) and in patients who underwent transcervical compared to transoral tumor resection (p = 0.008). Local recurrence rate was 57.1% with a disease-free survival of 17.6 months. CONCLUSION: The myocutaneous SAFF represents a safe and reliable flap for tongue reconstruction after salvage glossectomy with satisfying functional outcomes and low donor side morbidity.
