RESUMO

BACKGROUND: Osseous and osteocutaneous fibular free flaps are the workhorse of maxillomandibular reconstruction over 30 years after the initial description. Since 2019, we have routinely used the Spider Limb Positioner, adapted from its use in shoulder orthopedic procedures, for fibular free flap harvest. Herein, we describe this novel technique in our cohort. METHODS: We describe our intraoperative setup and endorse the versatility and utility of this technique in comparison to other reported fibular free flap harvest techniques. RESULTS: The Spider Limb Positioner was used 61 times in 60 different patients to harvest osseous or osteocutaneous fibular free flaps. Median (range) tourniquet time for flap harvest was 90 (40-124) minutes. No iatrogenic nerve compression injuries or complications related to lower extremity positioning occurred. CONCLUSION: We describe a novel approach to fibular free flap harvest utilizing the Spider Limb Positioner, which affords optimal ergonomics, visibility, and patient repositioning. There were no nerve injuries or complications related to positioning in our series.

RESUMO

IMPORTANCE: While there has been an increased understanding of the impact of visible neck scars in some patients with certain diseases, this has not yet been explored in the HPV+ OPSCC population. OBJECTIVE: To understand patients' perception of their scar and the impact on their quality of life (QOL) at least 6 months after neck dissection (ND) for HPV+ oropharyngeal squamous cell carcinoma (OPSCC). DESIGN, SETTING, AND PARTICIPANTS: In this retrospective case-control study, patients who underwent primary transoral robotic surgery (TORS) and ND for HPV+ OPSCC between 2016 and 2021 at a single tertiary care center were identified. Data analysis was performed in January 2022. MAIN OUTCOMES AND MEASURES: Dermatology Life Quality Index was modified (mDLQI) to assess patients' perceptions of their scars. The primary outcome was the mean mDLQI survey score with higher scores corresponding to worse perceptions. Three questions adapted from the Self-Consciousness Scale (SCS) were also included to assess awareness of appearance. All questions were scaled on a 0-3 Likert Scale. Tweedie generalized linear model was used to understand the relationship between mDLQI score and patient- and procedure-specific factors (including the three SCS survey questions). An additional exploratory logistic regression was performed to understand the risk factors for clinically significant mDLQI score change. RESULTS: A total of 67 patients (response rate 57 %) completed the survey with a mean mDLQI survey score of 0.84 (max 30). Although there was a statistically significant negative association between private insurance and mDLQI survey score (95 % Confidence Interval [CI]: -2.72 - -0.38), and a positive association between the SCS score and mDLQI survey score (95 % CI: 0.23-0.81) (p < 0.05), these variables were not found to be risk factors for a clinically significant difference in mDLQI on multivariable analysis. CONCLUSION: The majority of patients felt their neck scars did not interfere with their daily lives. Patient perceptions of neck scars were consistent despite differing patient characteristics and treatment regimens.

RESUMO

BACKGROUND: Following total laryngectomy (TL) or laryngopharyngectomy (TLP), patients may develop strictures that require multiple dilations to treat. However, the risk factors associated with dysphagia refractory to a single dilation are unknown. METHODS: Single-institution retrospective review of patients who underwent at least one stricture dilation after TL/TLP between March 2013 and March 2022. RESULTS: A total of 49 patients underwent stricture dilation after TL/TLP. Thirty-five (71%) underwent multiple dilations. Pharyngocutaneous fistula, primary chemoradiation therapy, and a shorter time interval from TL/TLP to first dilation were independently associated with dysphagia requiring multiple dilations. Patients in the multiple dilations group had a higher rate of limited diet and G-tube dependence compared to patients in the single dilation group. CONCLUSIONS: Shorter time interval to stricture formation is a prognostic indicator of the need for multiple dilations following TL/TLP. Patients requiring multiple dilations are at increased risk of persistent dysphagia long-term.

RESUMO

Importance: Despite the widespread use of fibula free flap (FFF) surgery for head and neck reconstruction, there are no studies assessing if early weight-bearing (EWB) affects postoperative recovery, and the timing of weight-bearing initiation following FFF surgery varies considerably across institutions. Therefore, it is important to understand the effect of EWB in these patients and whether it could improve postoperative recovery. Objective: To assess the association of EWB after FFF surgery with donor-site complications, length of stay, and discharge to home status. Design, Setting, and Participants: This retrospective cohort study took place at Massachusetts Eye and Ear, a single tertiary care institution in Boston, Massachusetts. A total of 152 patients who received head and neck reconstruction with a fibula osteocutaneous free flap between January 11, 2010, and August 11, 2022, were included. Exposure: EWB on postoperative day 1 vs non-EWB on postoperative day 2 or later. Main Outcomes and Measures: Patient characteristics, including demographic characteristics and comorbidities, surgical characteristics, donor-site complications, length of stay, and discharge disposition, were recorded. Descriptive statistics and multivariate logistic regressions were used to compute effect sizes and 95% CIs to compare postoperative outcomes in EWB and non-EWB groups. Results: A total of 152 patients (median [IQR] age, 63 [55-70] years; 89 [58.6%] male) were included. The median (IQR) time to postoperative weight-bearing was 3 (1-5) days. Among all patients, 14 (9.2%) had donor-site complications. EWB on postoperative day 1 was associated with shorter length of stay (adjusted odds ratio [AOR], 0.10; 95% CI, 0.02-0.60), increased rate of discharge to home (AOR, 7.43; 95% CI, 2.23-24.80), and decreased donor-site complications (AOR, 0.11; 95% CI, 0.01-0.94). Conversely, weight-bearing 3 or more days postoperatively was associated with an increased risk of pneumonia (AOR, 6.82; 95% CI, 1.33-34.99). Conclusions and Relevance: In this cohort study, EWB after FFF surgery was associated with shorter length of stay, increased rate of discharge to home, and decreased donor-site complications. These findings support the role of early mobilization to optimize postoperative recovery after FFF surgery.

RESUMO

OBJECTIVE(S): To characterize the change in sensory function following partial glossectomy for oral tongue cancer (OTC) and to identify predictors of loss of tongue-tip sensation (LoTTS). MATERIALS AND METHODS: Patients with at least three months follow-up after partial glossectomy for primary OTC were included. All patients underwent a qualitative tongue sensation assessment and an objective tongue sensory exam of the native tongue tip. Additional details regarding the oncologic resection, surgical reconstruction, and pathological stage were collected. Multiple linear and logistic regressions were used for statistical analysis. RESULTS: Sixty-four patients were enrolled, including 34 (53%) men with a median age of 65 at enrollment. Ten (15%) patients reported LoTTS. Increased depth of resection (DOR) was an independent predictor of LoTTS on multivariate analysis, with an increased risk at a threshold of 1.3 cm. LoTTS was also associated with worse subjective quality of life and perceptive speech performance in our qualitative tongue assessment. CONCLUSIONS: In this pilot study, we found that DOR is a critical prognostic factor in predicting post treatment function. Patients with an increased DOR, particularly above 1.3 cm, are at greatest risk of LoTTS and associated morbidity. These findings may be used to predict post-operative sensory deficits, manage patients' expectations, and optimize the reconstructive approach. Future studies are needed to validate and replicate our results.

RESUMO

The surgical resection of solid tumours can be enhanced by fluorescence-guided imaging. However, variable tumour uptake and incomplete clearance of fluorescent dyes reduces the accuracy of distinguishing tumour from normal tissue via conventional fluorescence intensity-based imaging. Here we show that, after systemic injection of the near-infrared dye indocyanine green in patients with various types of solid tumour, the fluorescence lifetime (FLT) of tumour tissue is longer than the FLT of non-cancerous tissue. This tumour-specific shift in FLT can be used to distinguish tumours from normal tissue with an accuracy of over 97% across tumour types, and can be visualized at the cellular level using microscopy and in larger specimens through wide-field imaging. Unlike fluorescence intensity, which depends on imaging-system parameters, tissue depth and the amount of dye taken up by tumours, FLT is a photophysical property that is largely independent of these factors. FLT imaging with indocyanine green may improve the accuracy of cancer surgeries.

RESUMO

BACKGROUND: Many options for free tissue transfer have been described for head and neck reconstruction. While functional outcomes remain paramount, aesthetic considerations like color match can be equally consequential for patient quality of life. It is important to understand differences in color match based on flap donor site for head and neck reconstruction. METHODS: A retrospective review was performed of patients who underwent head and neck reconstruction with free tissue transfer at a tertiary care academic medical center between November 2012 and November 2020. Patients with documented pictures of their reconstruction and external skin paddles were considered. Patient demographics and surgery specific factors were recorded. Objective differences in color match were obtained by calculating the International Commission on Illumination Delta E 2000 (dE2000) score. Standard univariate descriptive statistics and multivariable statistical analyses were performed. RESULTS: Lateral arm, parascapular, and medial sural artery perforator (MSAP) free tissue transfer performed favorably compared to other donor sites, whereas anterolateral thigh flaps had the highest average dE2000 scores. Differences in dE2000 scores were mitigated by post-operative radiation to the flap site and with increasing time beyond 6 months post-operatively. CONCLUSIONS: We provide an objective assessment of external skin color match in patients undergoing free tissue transfer for head and neck cancer by donor site. MSAP, lateral arm, and parascapular free flaps performed well compared to traditional donor sites. These differences are more significant at the face and mandible when compared to the neck, but diminish 6 months after surgery and with post-operative radiation to the free flap skin paddle.

RESUMO

BACKGROUND: Comparisons of patient-reported donor site morbidity based on the Disabilities in Arm, Shoulder, and Hand (DASH) instrument across upper trunk free flaps in head and neck surgery, including radial forearm (RFFF), osteocutaneous radial forearm (OCRFF), scapular tip (STFF), and serratus anterior (SAFF) free flaps, may help inform donor tissue selection. METHODS: In this meta-analysis, 12 studies were included and the primary outcome was average DASH score. RESULTS: The pooled DASH scores were 12.14 (95% CI: 7.40-16.88) for RFFF (5 studies), 17.99 (11.87-24.12) for OCRFF (2 studies), 12.19 (8.74-15.64) for STFF (3 studies), and 16.49 (5.92-27.05) for SAFF (2 studies) and were not significantly different. CONCLUSIONS: Results suggest that patients generally function well, with minimal to mild donor site morbidity, when assessed at an average of 20 months after flap harvest. These results are based on few effects from primarily retrospective studies of fair quality, and further research is needed.

RESUMO

OBJECTIVES: To develop a patient-reported outcomes measure (PROM) for total laryngectomy. STUDY DESIGN: Qualitative interviews with a purposive sample of patients with total laryngectomy, followed by cognitive debriefing interviews with patients and expert feedback. METHODS: Concept elicitation was performed using in-depth qualitative interviews with a purposive sample of patients who had undergone total laryngectomy. Patients were recruited from head and neck surgery and speech-language pathology clinics as well as via laryngectomy support groups. Interviews were conducted, recorded, transcribed, and coded, resulting in a conceptual framework and item pool. Using the item pool, preliminary scales were drafted. The scales were revised iteratively over 5 rounds using feedback from cognitive interviews with patients and multi-institutional and multi-disciplinary expert feedback. RESULTS: A total of 15 patients with total laryngectomy (mean age 68 years, range 57-79) were interviewed resulting in 1555 codes. The codes were used to form a conceptual framework grouped into top-level domains of stoma, function, health-related quality of life, devices, and experience of care. Items were used to form 15 preliminary scales that were revised over five rounds of cognitive debriefing interviews (n = 9 patients) and expert feedback (n = 17 experts). The field-test version of the LARY-Q has 18 scales and 277 items in total. CONCLUSIONS: The LARY-Q is a novel PROM designed to assess outcomes associated with total laryngectomy. The next step involves a field test study with a heterogenous sample of patients to assess the psychometric properties of the LARY-Q and perform item reduction.

RESUMO

OBJECTIVE: To identify the most frequently asked questions regarding "laryngectomy" through an assessment of online search data. METHODS: Google Search data based on the search term "laryngectomy" were analyzed using Google Trends and Search Response. The most common People Also Ask (PAA) questions were identified and classified by the concept. Each website linked to its respective PAA question was rated for understandability, ease of reading, and reading grade level. RESULTS: Search popularity for the term "laryngectomy" remained stable between 2017 and 2022. The most popular PAA themes were post-laryngectomy speech, laryngectomy comparison to tracheostomy, stoma and stoma care, survival/recurrence, and post-laryngectomy eating. Of the 32 websites linked to the top 50 PAA's, eleven (34%) were at or below an 8th grade reading level. CONCLUSION: Post-laryngectomy speech, eating, survival, the stoma, and the difference between laryngectomy and tracheostomy are the most common topics searched online in relation to "laryngectomy." These are important areas for both patient and healthcare provider education. LEVEL OF EVIDENCE: N/A Laryngoscope, 133:2971-2976, 2023.

RESUMO

BACKGROUND: Understanding the impact of surgical treatment on regionally metastatic cutaneous squamous cell carcinoma (cSCC). METHODS: Retrospective series of 145 patients undergoing parotidectomy and neck dissection for regionally metastatic cSCC to the parotid. Overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS) analyzed over 3 years. Multivariate analysis was completed using Cox proportional hazard models. RESULTS: OS was 74.5%, DSS was 85.5% and DFS was 64.8%. On multivariate analysis, immune status (HR = 3.225[OS], 5.119[DSS], 2.071[DFS]) and lymphovascular invasion (HR = 2.380[OS], 5.237[DSS], 2.595[DFS]) were predictive for OS, DSS, and DFS. Margin status (HR = 2.296[OS], 2.499[DSS]) and ≥18 resected nodes (HR = 0.242[OS], 0.255[DSS]) were predictive of OS and DSS, while adjuvant therapy was predictive of DSS (p = 0.018). CONCLUSIONS: Immunosuppression and lymphovascular invasion portended worse outcomes in patients with metastatic cSCC to the parotid. Microscopically positive margins and <18 nodes resected are associated with worse OS and DSS, while patients receiving adjuvant therapy had improved DSS.

RESUMO

OBJECTIVE: The laryngeal force sensor (LFS) measures force during suspension microlaryngoscopy (SML) procedures, and has been previously shown to predict postoperative complications. Reproducibility of its measurements has not been described. STUDY DESIGN: Prospective cohort study. SETTING: Academic medical center. METHODS: 291 adult patients had force data collected from 2017 to 2021 during various SML procedures. 94 patients had passive LFS monitoring (surgeon blinded to intraoperative recordings) and 197 had active LFS monitoring (surgeon able to see LFS recordings). 27 of these patients had repeat procedures, with unique LFS metrics for each procedure. The 27 patients were divided into three groups. Group 1 had passive use for both procedures, group 2 had passive use for the first procedure and active use for the second, and group 3 had active use for both procedures. Force metrics from the two procedures were compared with a paired samples t-test. RESULTS: For airway dilation procedures and cancer resection procedures, average force variances were significantly lower with active versus passive use of the LFS. Group 1-no significant changes in maximum force (procedure 1 = 163.8 N, procedure 2 = 133.8 N, p = 0.324) or average force (procedure 1 = 93.6 N, procedure 2 = 78.3 N, p = 0.617). Group 2-maximum force dropped by 35 % between procedures 1 (219.2 N) and 2 (142.5 N), p = 0.013. Average force dropped by 42.5 % between procedures 1 (147.2 N) and 2 (84.6 N), p = 0.007. Group 3-no significant changes in maximum force (procedure 1 = 158.6 N, procedure 2 = 158.2 N, p = 0.986) or average force (procedure 1 = 94.2, procedure 2 = 81.8, p = 0.419). CONCLUSIONS: LFS measurements were reproducible for similar procedures in the same patient when the type of LFS monitoring was not a confounder.

RESUMO

BACKGROUND: Understanding of nodal metastasis in patients with HPV+ oropharyngeal squamous cell carcinoma (OPSCC) is warranted. METHODS: Patients with HPV+ OPSCC who underwent neck dissection (ND) between 2016 and 2021 were reviewed. Pathology reports were reviewed for lymph node (LN) metastases. Noncontiguous metastases were defined as pathologic evidence of level II disease with another involved LN in a noncontiguous neck level. Skip metastases were defined as pathologic lymph node(s) in the neck without disease in level II. RESULTS: One hundred and thirty-one patients underwent levels II-IV ND with a mean (SD) LN yield of 33.3 (±13.5). The rate of atypical metastases in both the therapeutic and elective ND cohort was 5%. The noncontiguous and skip metastases were in level IV (n = 2) and level III (n = 4), respectively. CONCLUSIONS: Skip and noncontiguous metastases were rare in patients with HPV+ OPSCC undergoing surgical treatment. Surgeons may consider a selective ND omitting Level IV in select patients with HPV+ OPSCC undergoing surgery.

RESUMO

When thin and pliable free tissue is needed, the medial sural artery perforator (MSAP) flap provides an excellent option with minimal donor site morbidity. However, among its pitfalls include difficult patient positioning and surgeon ergonomics throughout the harvest. We describe a novel positioning technique that may significantly improve surgeon ergonomics and ease of MSAP flap harvest. A cross-legged modification may eliminate many of the issues associated with the classic frog-leg position. While the patient is cross-legged, the surgeon is afforded a normal field of view that is closer to their body, while simultaneously providing support to the lateral side of the gastrocnemius muscle. This pictorial essay describes this positioning technique and subsequent harvest. By incorporating a more ergonomic cross-legged position during flap elevation, many of thedrawbacks of the MSAP flap could be eliminated.

RESUMO

Head and neck squamous cell carcinoma (HNSCC) and its treatments are associated with substantial morbidity, often resulting in cosmetic deformity and loss of physiologic functions including speech and swallowing. Despite advancements in treatment, 5-year survival rates for mucosal malignancies remain below 70%. Effective prevention of HNSCC demands an understanding of the molecular pathways of carcinogenesis. Specifically, defining features of pre-cancerous dysplastic lesions that indicate a better or worse prognosis is necessary to help identify patients who are likely to develop a carcinoma and allow a more aggressive approach to management. There remains a need for identification of biomarkers that can provide both early prognostic and predictive value in clinical decision-making by serving as both therapeutic targets as well as predictors of therapy response. Here, we comprehensively review the most frequently altered molecular biomarkers of malignant transformation in head and neck dysplasia. These markers are involved in a wide range of cellular processes in head and neck carcinogenesis, including extracellular matrix degradation, cell motility and invasion, cell-cell adhesion, solute transport, immortalization, metabolism, the cell cycle and apoptosis, transcription, and cell signaling.

RESUMO

Objectives: To develop a novel laryngoscope device capable of dynamically measuring force and torque measurements in real-time during intubation and to explore the efficacy of such a device through a face validation simulation. Methods: The torque sensor laryngoscope is designed for use during intubation and is modeled after a standard, single-use plastic laryngoscope. After device calibration, a face validation study was performed with intubation experts in the field. Quantitative data (intubation force metrics) and qualitative data (expert feedback on the device) were collected from three intubations using a Mac blade and three intubations with the Miller blade. Results: Three experts (two anesthesiologists and one otolaryngologist) participated in the study. The mean maximum force exerted with the Mac blade was 24.5 N (95% confidence interval [CI], 22.3-26.8). The average force exerted was 13.6 N (95% CI, 11.7-15.5). The average total suspension time was 13.1 s (95% CI, 10.4-15.8). The average total impulse was 164.6 N·s (95% CI, 147.9-181.4). The mean maximum force exerted with the Miller blade was 31.6 N (95% CI, 26.4-36.8). The average force exerted was 15.8 N (95% CI, 13.8-17.9). The average total suspension time was 11.3 s (95% CI, 9.9-12.6). The average total impulse was 216.2 N·s (95% CI, 186.5-245.9). The mean maximum force (p = .0265) and total impulse (p = .009) were significantly higher in the Miller blade trials than in the Mac blade trials. Survey results found that this device, while bulky, intubated similarly to standard-use models and has potential as an intubation teaching tool. Conclusion: The torque sensor laryngoscope can measure and display real-time intubation force metrics for multiple laryngoscope blades. Initial validation studies showed a significantly lower maximum force and total impulse when intubating with the Mac blade than with the Miller blade. Face validation survey results were positive and suggested the potential for this device as a teaching tool. Level of Evidence: Level 5.

RESUMO

OBJECTIVE: Laryngeal fractures are rare injuries; recent data describing these injuries and associated examination findings are limited. This study aims to describe injury etiology and outcomes associated with laryngeal fractures. STUDY DESIGN: Retrospective case series. SETTING: Academic tertiary center. METHODS: Patients with laryngeal fractures from 2005 to 2020 were identified in a retrospective chart review. Patient demographics, injury mechanisms, management, and voice outcomes were examined. Fracture type, radiologic, and endolaryngeal examination findings were analyzed for associations between fracture etiology and examination characteristics. RESULTS: Laryngeal fractures most commonly occurred at the thyroid cartilage. Fractures were most commonly due to sport-related injuries. Mechanism of injury was not associated with specific radiologic or endolaryngeal findings. Mechanism of injury was additionally not significantly associated with the need for intubation, surgical intervention, or tracheotomy. Fracture location was significantly associated with intubation requirement (P = .015), with 40% of patients with concomitant thyroid and cricoid fractures requiring intubation. Mechanism of injury significantly correlated with dysphonia at follow-up (P = .033). Mechanism of injury, fracture location, and surgical management were not associated with increased vocal fold injury or dysphonia. CONCLUSION: There are no significant correlations between injury mechanism and fracture location, characteristics, radiologic findings, or endolaryngeal findings. These features emphasize the importance of a thorough and comprehensive laryngeal examination.

RESUMO

Objectives This article examines a national cohort of patients with nasopharyngeal adenoid cystic carcinoma (ACC) for incidence, skull base invasion, overall survival, and treatment paradigms. Design, Setting, and Participants Retrospective national population-based study using Surveillance, Epidemiology, and End Results program data of patients with ACC of the nasopharynx (NACC) and skull base between 2004 and 2016. Main Outcomes and Measures Primary outcomes included 5-year overall survival and odds of radiation treatment. Statistical analysis was performed using STATA 15.0 (STATACorp). p -Values < 0.05 were considered statistically significant. Results Of the 2,385 cases of ACC, 70 cases were classified as NACC. Twenty-one percent (15) involved invasion of the skull base or posterior pharyngeal wall, and 42% (30) were either stage 3 or stage 4. The 5-year overall survival for patients with NACC without skull base invasion was 67% which dropped to 40% with invasion into the skull base. Radiation was used as the primary form of therapy for 62% of NACC and 73% of NACC invading into skull base. Odds of receiving radiation therapy and 5-year survival were not affected by socioeconomic status or density of providers. Conclusion NACC is rare in incidence and was most commonly treated with radiation therapy when advanced in stage. Prognosis was dependent on invasion through posterior pharyngeal wall and skull base. Provider density and socioeconomic status did not affect odds of radiation or overall survival for NACC.

RESUMO

Free tissue transfer from the subscapular system provides a wide array of options for both soft tissue and bony reconstruction. When bone stock is required for head and neck reconstruction, both the lateral scapular border free flap (LSBFF), supplied by the circumflex scapular artery, and the scapular tip free flap (STFF), supplied by the angular artery, are excellent options. Issues with positioning had previously prevented the widespread use of these bony subscapular system flaps. However, through the use of a Spider Limb Positioner, current clinical practice patterns allow for two team approaches in both of these free flaps. The following pictorial essay compares and contrasts the specific positioning and harvesting technique used for both the LSBFF and STFF, while discussing the clinical advantages and drawbacks of each. Both the lateral border scapula and scapular tip free flaps provide excellent bone stock for head and neck reconstruction. By positioning with currently available technology, both of these free flaps can be harvested through a two team approach.
