Determining Patient Preferences for Indeterminate Thyroid Nodules: Observation, Surgery or Molecular Tests.

BACKGROUND: Gene-expression classifiers (GEC) and genetic mutation panels (GMP) have been shown to improve preoperative diagnostic evaluations of indeterminate thyroid nodules. Despite the improvement, uncertainty regarding the proper management exists. Patient preferences may better inform the management of these indeterminate thyroid nodules. METHODS: Hypothetical scenarios were administered to two groups of patients: those with previous FNA-confirmed indeterminate thyroid nodules (Group A, n = 50) and those presenting to a general otolaryngology clinic for other reasons (Group B, n = 50). We evaluated patient preferences for surgery, observation and the use of molecular tests while varying the risk of malignancy, cost and diagnostic properties of the tests. RESULTS: The mean threshold for choosing surgery over observation was a 38.6% risk of malignancy on FNA. When offered either GEC, GMP or both (with their inherent imperfect diagnostic properties) in addition to the indeterminate FNA, 85.0% of respondents picked at least one of the molecular tests over either observation or surgery if the test(s) were free of charge. However, only 51.7% of respondents chose at least one of the tests when asked to pay the current cost of the test(s) (p < 0.001). On multivariable analysis, sex, the presence of an indeterminate FNA diagnosis and income level significantly predicted the desire to proceed with a molecular test above standard management. CONCLUSION: Patient preferences for thyroid nodule management are dependent on the risk of malignancy, prognosis of cancer and costs. Patients prefer molecular tests over standard management with indeterminate thyroid nodules, but the costs of the test(s) reduce the desire.

Facial nerve reconstruction and facial disfigurement after radical parotidectomy.

BACKGROUND: The importance of facial contouring with facial nerve reconstruction following total and radical parotidectomy is often overlooked. The goal of this study was to quantify the level of facial disfigurement and nerve dysfunction following reconstruction of the facial nerve, with or without reconstruction of the contours, using free tissue transfer. METHODS: A total of 26 patients with radical parotidectomy and facial nerve reconstruction were included in this retrospective study. Of the 26 patients, 15 underwent follow-up interviews and evaluation of facial nerve function and disfigurement using three different scales: the regional House-Brackmann (H-B) scale, the Facial Clinimetric Evaluation (FaCE) Scale, and the observer-rated disfigurement scale. RESULTS: Of the 15 evaluated patients, 8 patients underwent free tissue transfer. Mean follow-up time was 39 months (median, 35; range, 11-65 months). Of the 15 patients, 10 patients had good or moderate function according to the H-B mouth scale (median score, 4; range, 2-5), and satisfactory eye closure was observed in 10 patients (median score, 3; range, 2-5). The mean disfigurement value rated by the physician was 5 (scale, 1-9), with a mean patient rating of 4. Subjective total FaCE score varied significantly (mean, 52; range, 13-93). CONCLUSIONS: Facial nerve and soft tissue reconstruction are highly beneficial to patients undergoing radical parotidectomy.

Telemedicine-enabled biofeedback electropalatography rehabilitation (TEBER): A pilot study for patients treated with surgery for oral cavity carcinoma.

BACKGROUND: To address the rehabilitative barriers to frequency and precision of care, we conducted a pilot study of a biofeedback electropalatography (EPG) device paired with telemedicine for patients who underwent primary surgery +/- adjuvant radiation for oral cavity carcinoma. We hypothesized that lingual optimization followed by telemedicine-enabled biofeedback electropalatography rehabilitation (TEBER) would further improve speech and swallowing outcomes after "standard-of-care" SOC rehabilitation. METHOD: Pilot prospective 8-week (TEBER) program following 8 weeks of (SOC) rehabilitation. RESULTS: Twenty-seven patients were included and 11 completed the protocol. When examining the benefit of TEBER independent of standard of care, "range-of-liquids" improved by +0.36 [95% CI, 0.02-0.70, p = 0.05] and "range-of-solids" improved by +0.73 [95% CI, 0.12-1.34, p = 0.03]. There was a positive trend toward better oral cavity obliteration; residual volume decreased by -1.2 [95% CI, -2.45 to 0.053, p = 0.06], and "nutritional-mode" increased by +0.55 [95% CI, -0.15 to 1.24, p = 0.08]. CONCLUSION: This pilot suggests that TEBER bolsters oral rehabilitation after 8 weeks of SOC lingual range of motion.

Association of two BRM promoter polymorphisms with head and neck squamous cell carcinoma risk.

The SWI/SNF chromatin remodeling complex is an important regulator of gene expression that has been linked to cancer development. Expression of Brahma (BRM), a critical catalytic subunit of SWI/SNF, is lost in a variety of solid tumors. Two novel BRM promoter polymorphisms (BRM-741 and BRM-1321) have been correlated with BRM loss and elevated cancer risk. The aim(s) of this study were to examine BRM expression in head and neck squamous cell carcinoma (HNSCC) and to correlate BRM polymorphisms with HNSCC risk. BRM expression studies were performed on eight HNSCC cell lines and 76 surgically resected tumor samples. A case-control study was conducted on 668 HNSCC patients (oral cavity, oropharynx, larynx and hypopharynx) and 700 healthy matched controls. BRM expression was lost in 25% of cell lines and 16% of tumors. The homozygous genotype of each polymorphism was significantly associated with increased HNSCC risk [BRM-741: adjusted odds ratio (aOR) 1.75, 95% CI 1.2-2.3, P < 0.001; BRM-1321: aOR 1.65, 95% CI 1.2-2.2, P < 0.001]. Individuals that were homozygous for both BRM polymorphisms had a more than 2-fold increase in the risk of HNSCC (aOR 2.23, 95% CI 1.5-3.4, P < 0.001). A particularly elevated risk was seen within the oropharynx, human papillomavirus-positive subgroup for carriers of both homozygous variants (aOR 3.09, 95% CI 1.5-6.8, P = 0.004). BRM promoter polymorphisms appear to act as susceptibility markers of HNSCC with potential utility in screening, prevention and treatment.

Glossectomy for the treatment of oral cavity carcinoma: Quantitative, functional and patient-reported quality of life outcomes differ by four glossectomy defects.

OBJECTIVE: The goal was to characterize four clinically distinct glossectomy defects to establish significant quantitative cut points using functional metrics, the MD Anderson Dysphagia Index (MDADI) and speech intelligibility. METHODS: Population included 101 patients treated with surgery, adjuvant radiation per NCCN guidelines, and ≥ 12 months follow-up. RESULTS: Defect groups: subtotal hemiglossectomy (1), hemiglossectomy (2), extended hemiglossectomy (3) and oral glossectomy (4) were compared: All outcomes supported a four defect model. Intergroup comparison of outcomes with subtotal hemiglossectomy as reference (p value): Tongue Protrusion <0.001,<0.001,<0.001; Elevation <0.001,<0.001,<0.001; Open Mouth Premaxillary Contact Elevation <0.001,<0.001,<0.001; Obliteration 0.6,<0.001,<0.001; Normalcy of Diet, <0.3,<0.001,<0.001; Nutritional Mode, <0.9,<0.8,<0.001; Range of Liquids, <0.4,<0.016,<0.02; Range of Solids, <0.5,<0.004,<0.001; Eating in Public, <0.2,<0.002,<0.03; Understandability of Speech, <0.9,<0.001,<0.001; Speaking in Public, <0.4,<0.03,<0.001; MDADI, <0.4,<0.005,<0.01; Single Word Intelligibility, <0.4,<0.1,<0.001; Sentence Intelligibility, <0.5,<0.08,<0.001; Words Per Minute Intelligibility, <0.6,<0.04,<0.001; Sentence Efficiency Ratio, <0.4,<0.03,<0.002. Proportion of patients by 4 defect groups who underwent: tissue transplantation, 51%,93.9%,100%,100%.Radiation,24%,67%,88%,80%.Between hemiglossectomy and extended hemiglossectomy, the defect extends into the contralateral floor of the mouth and/or the anterior tonsillar pillar; resection of these subunits limits tongue mobility with an impact on functional outcome and MDADI. Between extended hemiglossectomy and oral glossectomy, the defect extends to include the tip of the tongue and appears to impact functional outcome and MDADI. CONCLUSIONS: Subtotal hemiglossectomy, hemiglossectomy, extended glossectomy and oral glossectomy are associated with quantitative (elevation, protrusion, open mouth premaxillary contact and obliteration), qualitative (speech and swallowing) and MDADI differences, suggesting that these 4 ordinal defect groups are distinct.

Extubation of a difficult airway after thyroidectomy: use of a flexible bronchoscope via the LMA-Classic™.

PURPOSE: We report an extubation strategy for a patient scheduled for thyroidectomy who had several factors indicating that it would be a difficult extubation. CLINICAL FEATURES: A 75-yr-old man with thyroid cancer presented for total thyroidectomy. He had anatomical features predictive of a difficult upper airway. Therefore, his trachea was intubated while he was awake using a flexible bronchoscope. The tumour had invaded the trachea, necessitating total thyroidectomy, 3-cm tracheal resection, and primary tracheal anastomosis. The left recurrent laryngeal nerve (RLN) was inherently involved in the tumour and sacrificed. A "guardian suture" placed between the chin and the chest maintained the head and neck in flexion, thereby avoiding traction on the tracheal anastomosis. Immediate postoperative extubation was desirable, given the new tracheal anastomosis; however, complicating factors included left RLN paralysis, tracheal anastomosis, potential for tracheomalacia or supraglottic airway swelling, and the guardian suture preventing neck extension. In addition, there were anatomical features raising the suspicion of difficult reintubation should it be necessary. With the patient deeply anesthetized, the endotracheal tube was removed and replaced with the Laryngeal Mask Airway (LMA)-Classic™ as a bridging device to facilitate bronchoscopic examination. It allowed us to visualize the tracheal repair, tracheal movement, vocal cord function, and supraglottic structures. The patient emerged from anesthesia and was extubated uneventfully. CONCLUSION: We describe a viable extubation strategy used in a patient after complex thyroid surgery involving tracheal resection. By using the LMA-Classic™ as a bridging device and to facilitate bronchoscopic examination, we were able to address the above concerns and safely manage the extubation phase in this patient.

A Quantitative Analysis Examining Patients' Choice of Active Surveillance or Surgery for Managing Low-Risk Papillary Thyroid Cancer.

Background: It is important to understand patient preferences on managing low-risk papillary thyroid cancer (PTC). Methods: We prospectively followed patients with low-risk PTC <2 cm in maximal diameter, who were offered the choice of thyroidectomy or active surveillance (AS) at the University Health Network (UHN), in Toronto, Canada. The primary outcome was the frequency of AS choice (percentage with confidence interval [CI]). Univariate and multivariable analyses were performed to identify predictors of the choice of AS. Results: We enrolled 200 patients of median age 51 years (interquartile range 42-62). The primary tumor measured >1 cm in 55.5% (111/200) of participants. The AS was chosen by 77.5% [71.2-82.7%, 155/200] of participants. In a backwards conditional regression model, the clinical and demographic factors independently associated with choosing AS included: older age (compared with referent group <40 years)-age 40-64 years-odds ratio (OR) 2.78 [CI, 1.23-6.30, p = 0.014], age ≥65 years-OR 8.43 [2.13-33.37, p = 0.002], and education level of high school or lower-OR 4.41 [1.25-15.53, p = 0.021]; AS was inversely associated with the patient's surgeon of record being affiliated with the study hospital-OR 0.29 [0.11-0.76, p = 0.012]. In a separate backwards conditional logistic regression model examining associations with psychological characteristics, AS choice was independently associated with a fear of needing to take thyroid hormones after thyroidectomy-OR 1.24 [1.11-1.39, p < 0.001], but inversely associated with fear of PTC progression-OR 0.94 [0.90-0.98, p = 0.006] and an active coping mechanism ("doing something")-OR 0.43 [0.28-0.66, p < 0.001]. Conclusions: Approximately three-quarters of our participants chose AS over surgery. The factors associated with choosing AS included older age, lower education level, and having a surgeon outside the study institution. Patients' fears about either their PTC progressing or taking thyroid hormone replacement as well as the level of active coping style were associated with the decision. Our results inform the understanding of patients' decisions on managing low-risk PTC. Registration: Clinicaltrials.gov NCT03271892.

Needs assessment for a decision support tool in oral cancer requiring major resection and reconstruction: a mixed-methods study protocol.

INTRODUCTION: Advanced oral cancer and its ensuing treatment engenders significant morbidity and mortality. Patients are often elderly with significant comorbidities. Toxicities associated with surgical resection can be devastating and they are often highlighted by patients as impactful. Given the potential for suboptimal oncological and functional outcomes in this vulnerable patient population, promotion and performance of shared decision making (SDM) is crucial.Decision aids (DAs) are useful instruments for facilitating the SDM process by presenting patients with up-to-date evidence regarding risks, benefits and the possible postoperative course. Importantly, DAs also help elicit and clarify patient values and preferences. The use of DAs in cancer treatment has been shown to reduce decisional conflict and increase SDM. No DAs for oral cavity cancer have yet been developed.This study endeavours to answer the question: Is there a patient or surgeon driven need for development and implementation of a DA for adult patients considering major surgery for oral cancer? METHODS AND ANALYSIS: This study is the first step in a multiphase investigation of SDM during major head and neck surgery. It is a multi-institutional convergent parallel mixed-methods needs assessment study. Patients and surgeon dyads will be recruited to complete questionnaires related to their perception of the SDM process (nine-item Shared Decision-Making Questionnaire, SDM-Q-9 and SDM-Q-Doc) and to take part in semistructured interviews. Patients will also complete questionnaires examining decisional self-efficacy (Ottawa Decision Self-Efficacy Scale) and decisional conflict (Decisional Conflict Scale). Questionnaires will be completed at time of recruitment and will be used to assess the current level of SDM, self-efficacy and conflict in this setting. Thematic analysis will be used to analyse transcripts of interviews. Quantitative and qualitative components of the study will be integrated through triangulation, with matrix developed to promote visualisation of the data. ETHICS AND DISSEMINATION: This study has been approved by the research ethics boards of the Nova Scotia Health Authority (Halifax, Nova Scotia) and the University Health Network (Toronto, Ontario). Dissemination to clinicians will be through traditional approaches and creation of a head and neck cancer SDM website. Dissemination to patients will include a section within the website, patient advocacy groups and postings within clinical environments.

A Prospective Mixed-Methods Study of Decision-Making on Surgery or Active Surveillance for Low-Risk Papillary Thyroid Cancer.

Background: Active surveillance (AS) of small, low-risk papillary thyroid cancers (PTCs) is increasingly being considered. There is limited understanding of why individuals with low-risk PTC may choose AS over traditional surgical management. Methods: We present a mixed-methods analysis of a prospective observational real-life decision-making study regarding the choice of thyroidectomy or AS for management of localized, low-risk PTCs <2 cm in maximum diameter (NCT03271892). Patients were provided standardized medical information and were interviewed after making their decision (which dictated disease management). We evaluated patients' levels of decision-self efficacy (confidence in medical decision-making ability) at the time information was presented and their level of decision satisfaction after finalizing their decision (using standardized questionnaires). We asked patients to explain the reason for their choice and qualitatively analyzed the results. Results: We enrolled 74 women and 26 men of mean age 52.4 years, with a mean PTC size of 11.0 mm (interquartile range 9.0, 14.0 mm). Seventy-one patients (71.0% [95% confidence interval 60.9-79.4%]) chose AS over surgery. Ninety-four percent (94/100) of participants independently made their own disease management choice; the rest shared the decision with their physician. Participants had a high baseline level of decision self-efficacy (mean 94.3, standard deviation 9.6 on a 100-point scale). Almost all (98%, 98/100) participants reported high decision satisfaction. Factors reported by patients as influencing their decision included the following: perceived risk of thyroidectomy or the cancer, family considerations, treatment timing in the context of life circumstances, and trust in health care providers. Conclusions: In this Canadian study, ∼7 out of 10 patients with small, low-risk PTC, who were offered the choice of AS or surgery, chose AS. Personal perceptions about cancer or thyroidectomy, contextual factors, family considerations, and trust in health care providers strongly influenced patients' disease management choices.

Postoperative wound infections, neutrophil-to-lymphocyte ratio, and cancer recurrence in patients with oral cavity cancer undergoing surgical resection.

BACKGROUND: It is unclear whether postoperative wound infections after head and neck cancer surgery are associated with cancer progression. METHODS: Patients undergoing surgery for oral cancer from 1998 to 2011 were reviewed. Univariable analyses and multivariable were performed. Propensity scores were used to create matched cohorts for infection and non-infection groups. Neutrophil-to-lymphocyte ratios (NLR) were determined prior to surgery and at the time of infection. RESULTS: Of 551 patients with oral cancer treated with surgery, 98 developed wound infections (18%). Tumor factors associated with wound infections included higher T and N category, extranodal extension, depth of invasion, lymphovascular and perineural invasion (p < 0.02 for all). On univariable analysis, wound infection was a predictor for recurrence free survival (p < 0.001), locoregional control (p = 0.01), and distant control (p < 0.001). Wound infection was not a predictor of overall survival (p = 0.88), recurrence free survival (p = 0.17), locoregional control (p = 0.79) or distant control (p = 0.18) on multivariable analysis. Using a propensity score matched cohort of 83 patients with and without infection, wound infection was not associated with recurrence free survival (p = 0.21), overall survival (p = 0.71), and locoregional control (p = 0.84), although there was a trend towards increased distant metastases (p = 0.10). Patients with wound infection had a greater preoperative NLR as well as a greater rise in the NLR after surgery, but these were not associated with survival or recurrence. CONCLUSIONS: Patients with wound infections have more adverse pathologic features. However, wound infection was not associated with poorer cancer outcomes although a trend towards increased distant metastases should be investigated.

Survival outcomes for cutaneous angiosarcoma of the scalp versus face.

BACKGROUND: The primary purpose of this study was to examine whether angiosarcoma outcomes differ for the scalp and face. METHODS: We conducted a retrospective outcomes analysis of 50 patients with cutaneous angiosarcoma treated by curative intent identified from the Princess Margaret Cancer Centre Registry (from 1958 to 2014). RESULTS: Median survival was 26 months (95% confidence interval [CI], 17.6-34.6) and median follow-up 29 months. For the scalp and face, respectively, the 5-year locoregional control rate was 9% and 53% (p = .04); the recurrence-free survival (RFS) rate was 5% and 27% (p = .017); and the overall survival (OS) rate was 9% and 26% (p = .017). Scalp lesions were larger, more likely to be multifocal, and presented more rapidly once noticed. In multivariate Cox proportional hazards analysis, scalp location was independently prognostic for mortality (hazard ratio [HR], 2.10; 95% CI, 1.03-4.28; p = .04). CONCLUSION: Scalp angiosarcoma has worse survival than angiosarcoma of the face. Scalp angiosarcoma tends to be larger at presentation, which may be because it is not noticed until more advanced. © 2017 Wiley Periodicals, Inc. Head Neck 39: 1205-1211, 2017.

Hardware complications in oromandibular defects: Comparing scapular and fibular based free flap reconstructions.

BACKGROUND: Despite improvements in surgical technique and technology, hardware complications occur relatively frequently. This study analyzes hardware complications in patients undergoing oromandibular reconstruction using scapular (SFF) or fibular (FFF) free flaps. METHODS: Retrospective data for 178 patients was obtained (1999-2014) at University Hospital Network (Toronto, Canada). Univariable and multivariable analyses were performed to identify risk factors for hardware complications. RESULTS: Patients with FFF reconstruction (n=129) had significantly more hardware complications than those with SFF (n=49) (16% vs. 2%;p=0.01). Surgical site infection (SSI) (OR=7.05; p<0.01), defect type (OR=2.63; p<0.01) and flap (OR=0.12; p=0.01) were significant predictors of hardware complications on univariable analysis. Flap type (OR=0.12; p=0.04) was an independent predictor of plate complication after adjusting for SSI. A subgroup analysis suggested a trend towards fewer hardware complications with SFF stratified by mandibular defect type. CONCLUSIONS: Scapular free flaps are associated with a lower rate of hardware-related complications in oromandibular reconstruction.

Lymph node ratio relationship to regional failure and distant metastases in oral cavity cancer.

BACKGROUND: We aimed to investigate the impact of lymph node ratio (LNR, number of positive nodes/total number of excised nodes) on regional-only-failure, distant-only-failure and overall survival (OS) in oral squamous cell carcinoma (OSCC). METHODS: Retrospective review of pN0-2 OSCC-patients (1994-2012) treated with curative-surgery with neck dissection±postoperative radiotherapy (PORT)±concurrent chemotherapy. LNR was subjected to multivariable analysis (MVA) of regional-only-failure, distant-only-failure and OS. RESULTS: Overall 914 patients were identified; median follow-up: 51months (1-189); pN0: 482 (52.7%), pN1: 128 (14%), pN2a: 6 (0.7%); pN2b: 225 (24.6%); pN2c: 73 (8%); median number of dissected nodes: 36 (6-125); median number of pN+: 2 (1-49); median LNR for pN+ patients: 6%; extranodal extension: 187 (20.5%). Bilateral neck dissection: 368 (40.3%); PORT: 452 (49.5%); and concurrent chemotherapy: 80 (8.8%). High grade, lymphovascular invasion perineural invasion and pT3-4 were associated with high LNR. On MVA, LNR was associated with regional-only-failure (HR=1.06; 95%CI: 1.04-1.08; p<0.001), distant-only-failure (HR=1.03; 95%CI: 1.02-1.05; p=0.004) and lower OS (HR=1.03; 95%CI: 1.02-1.05; p<0.001). Similarly, in pN2-subgroup: LNR was associated with regional-only-failure (HR=1.04; 95%CI: 1.02-1.06; p<0.001), distant-only-failure (HR=1.03; 95%CI: 1.01-1.06; p=0.045) and lower OS (HR=1.03; 95%CI: 1.02-1.04; p<0.001). CONCLUSION: High LNR is associated with higher regional-only-failure/distant-only-failure and lower OS. LNR should be assessed in future prospective trials for selection of adjuvant therapy.

Comorbidity and performance status as independent prognostic factors in patients with head and neck squamous cell carcinoma.

BACKGROUND: The purpose of this study was to evaluate the individual and combined relationship of comorbidity and performance status (PS) on head and neck squamous cell carcinoma (HNSCC) survival. METHODS: Six hundred patients with HNSCC were prospectively recruited. Comorbidity and PS were measured using the Charlson Comorbidity Index (CCI) and the Eastern Cooperative Oncology Group (ECOG) Scale. Outcomes were overall survival (OS) and cancer-specific survival (CSS). RESULTS: A total of 48.3% of the patients had at least 1 comorbidity, and 42.3% had impaired PS at baseline. There was no correlation between CCI and ECOG (Spearman's ρ = 0.033; p = .42). In multivariate analysis, CCI score was significantly associated with OS (p = .01). ECOG was not associated with OS, but seems to act as an effect modifier in the association between comorbidity and OS. CCI and ECOG were not associated with CSS. CONCLUSION: CCI and ECOG scores both provide prognostic information in predicting OS in HNSCC, but a significant association with CSS was not observed.

Salvage surgery for locally recurrent oropharyngeal cancer.

BACKGROUND: There are limited data on whether recurrent human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (SCC) is associated with higher surgical salvage rates. The purpose of this study was to determine the success rate of salvage surgery for locally recurrent oropharyngeal cancer and factors influencing the outcome, including p16 status. METHODS: All patients who underwent salvage surgery for locally recurrent or persistent oropharyngeal cancer after (chemo)radiotherapy between 2000 and 2012 were included. The Kaplan-Meier analysis was used to determine overall survival (OS) and recurrence-free survival (RFS). Univariable analysis was performed using Cox proportional hazards regression. RESULTS: Thirty-four patients underwent salvage surgery. Five patients (14.7%) were tracheostomy dependent and 22 (64.7%) were gastrostomy tube dependent after salvage surgery. Postoperative complications occurred in 15 patients. RFS after salvage surgery was 28% and 19% at 3 and 5 years, respectively. The presence of nodal disease at the time of local recurrence, close or positive margins, and lymphovascular invasion were the only factors associated with worse survival on univariable analysis. HPV status based on p16 testing was not associated with either OS or RFS. CONCLUSION: Surgical salvage for oropharyngeal SCC after failure of radiotherapy (+/- chemotherapy) is feasible. Patients who may benefit from surgery include those without regional recurrence and/or those in whom negative margins can be obtained. However, patients may be tracheotomy or gastrostomy tube dependent. The p16 status did not seem to have prognostic impact in the salvage setting; however, larger series are required to assess this relationship. © 2015 Wiley Periodicals, Inc.

The sternomastoid branch of the occipital artery: a surgical landmark for the spinal accessory nerve in selective neck dissections.

OBJECTIVE: To evaluate the anatomic relationship between the spinal accessory nerve (SAN) and the sternomastoid branch of the occipital artery (SBOA) and its utility as a surgical landmark during a selective neck dissection (SND). STUDY DESIGN AND SETTINGS: Consecutive patients undergoing SND for squamous cancer from October 1, 2004 to February 28, 2005 were enrolled in this study. During surgery the distance between the SBOA and the point of insertion of the SAN into the sternomastoid muscle (SMM) was measured. RESULTS: Twenty-four patients underwent 33 SND. The distance between the SBOA and SAN ranged between 1 and 11 mm, with a mean of 6.2 mm and a median of 6 mm. CONCLUSION: The relationship between these 2 structures has a range and constancy that is acceptable as a landmark. SIGNIFICANCE: This article presents a useful adjunct for location of the SAN in the anterior neck during SND.

Patient education and informed consent in head and neck surgery.

OBJECTIVE: To examine the effects of an educational intervention, in the form of printed material, on patient knowledge and recall of possible risks from parotidectomy or thyroidectomy. DESIGN: Prospective, randomized, controlled study conducted during a 9-month period. SETTING: Head and neck surgery clinic of an academic tertiary care hospital. PATIENTS: One hundred twenty-five consecutive patients older than 16 years who were undergoing thyroidectomy or parotidectomy at the head and neck surgery clinic were recruited. Four patients were excluded from analysis because their follow-up interview was not within the required limits. INTERVENTION: At the preoperative visit during the routine consent process, both groups received a verbally delivered checklist of risks specific for the surgery to be performed. The intervention group was also given a pamphlet with written information accompanied by illustrations. MAIN OUTCOME MEASURES: The effectiveness of the educational intervention was determined by comparing the average rate of risk recall between the intervention and control groups. The effects of age, sex, level of education, and time between the consent and recall interviews on recall rate were also assessed. RESULTS: The overall risk recall rate for both procedures was 39.1%. The recall rate of the intervention group was 50.3% compared with 29.5% for the control group (P<.001). CONCLUSIONS: The intervention consistently improved risk recall for all patients regardless of age, sex, and level of education. Patients' ability to recall potential risks was significantly increased by an educational intervention; all patients would benefit from this intervention.

Scalp and forehead reconstruction using free revascularized tissue transfer.

OBJECTIVE: To examine the indications for, and the success of, free flap reconstruction in patients with forehead and scalp defects. DESIGN: Case series. SETTING: Two tertiary referral university teaching hospitals. Patients Twenty-six consecutive patients, aged 31 to 85 years, presenting with 26 scalp defects, 5 forehead defects, and 1 combined defect (size, 70-672 cm(2)). Three patients required resection and repair of the dura at surgery. Intervention Patients were staged according to the size of the defect and the viability of surrounding tissue; free flap reconstruction was performed where indicated. MAIN OUTCOME MEASURES: Flap survival, complications, and disease-free and overall survival. RESULTS: Thirty-four free flap reconstructions were performed (24 latissimus dorsi free flaps, 4 scapular free flaps, 3 rectus abdominis free flaps, and 3 radial forearm free flaps). One failed 2 weeks postoperatively, and 2 required exploration (1 for arterial ischemia and 1 for a hematoma). There were 3 cases of donor site morbidity (2 early seromas and 1 late abdominal hernia). One patient died of a pulmonary embolus 1 week postoperatively. Disease-free survival was 48% at 5 years and overall survival was 59% at 5 years, with a median follow-up of 24 months. CONCLUSIONS: Free revascularized tissue transfer is a reliable and safe way of reconstructing large scalp or forehead defects after traumatic injury or neoplastic resection. The muscle-only latissimus dorsi free flap for scalp reconstruction and the cutaneous scapular free flap for the forehead have proved successful in selected patients with a low complication rate and satisfactory cosmesis.

Medial mandibulotomies: is there sufficient space in the midline to allow a mandibulotomy without compromising the dentition?

OBJECTIVES: The objective of this study was to determine the frequency of complications in median and paramedian mandibulotomies. In addition, the interdental space in the median and paramedian region was calculated. STUDY DESIGN: Retrospective study. SETTING: Tertiary care center. METHODS: A retrospective chart review was performed for all cases where a mandibulotomy was performed from 2002 to 2010. 117 charts (61 paramedian and 56 median) were identified. We included data on complications, which fell in the following 2 categories: plate and dental complications. For our second objective, we evaluated 40 different patients with base of tongue or tonsillar cancer treated with intensity modulated radiation therapy (IMRT). The interdental space between the lateral incisors and the canines was electronically calculated on the digital Panorex images. MAIN OUTCOME MEASURES: Dental and plate complications were evaluated. We also assessed interdental space. RESULTS: Patient characteristics were not significantly different. The median group had significantly more dental complications (p=0.0375, RD=0.19 and 95% CI (0.0139-0.3661)). The paramedian group had significantly more plate complications (p=0.0375, RD=0.082 and 95% CI (0.0131-0.1508). The distance between the central incisors was significantly less than the distance between the lateral incisors and canines both at the crestal and apical levels (p=0.0086 and p<0.001). CONCLUSIONS: There are significantly more dental complications in the median approach. There were significantly more plate complications in the paramedian group. In addition, there is significantly less space in the between the median region as compared to the paramedian region. This is the first study that documents the advantage of the paramedian approach for dental complications.

Outcomes of squamous cell cancer of the oral tongue managed at the Princess Margaret Hospital.

BACKGROUND: The purpose of this study was to analyze the outcomes and treatment in patients with squamous cell carcinoma (SCC) of the oral tongue, as well as validate previously reported predictors of survival. METHODS: We retrospectively reviewed 259 patients treated with curative intent between 1994 and 2004. Kaplan-Meier estimates, log-rank test, and Cox regression models were used for statistical analysis. RESULTS: Two hundred fifty-nine patients were managed with surgery; 67 patients (25%) received adjuvant radiotherapy. Mean follow-up was 60 months. The 5-year local and regional control rates were 78% and 69.4%, respectively. The 5-year overall, disease-specific, and recurrence-free survival rates were 69%, 70.9%, and 53%, respectively. The only significant predictor of both overall survival (OS) and disease-free survival (DFS) on multivariable analysis was pathologic N classification. CONCLUSION: Treatment of early tongue SCC effectively achieves local control and DFS. Nodal disease remains to be 1 of the most important prognostic factors in terms of recurrence and survival.
