The Functional & Quality of Life Outcomes of Total Glossectomy with Laryngeal Preservation.

BACKGROUND: The tongue is an essential organ for human interaction, communication and survival. To date, there is a paucity of objective functional, patient reported, or quality of life outcomes of patients undergoing a total glossectomy with preservation of the larynx (TGLP). OBJECTIVE: To examine prospectively collected objective, self-reported functional and quality of life (QOL) data in patients undergoing TGLP and free flap reconstruction. METHODS: Sixteen TGLP patients were identified in the prospective head and neck cancer and functional outcomes database between January of 2009 and December 2017. Data collection included patient age, sex, performance status, TNM staging, diagnosis and adjuvant treatment. Swallowing and speech functions were measured and prospectively recorded pre- and postoperatively. Patient reported outcomes were measured with the Speech Handicap Index (SHI) and the M.D. Anderson Dysphagia Inventory (MDADI). RESULTS: All patients had a significant reduction in their objective swallowing (P = 0.035), sentence (P = 0.001) and word intelligibility (P < .001) scores. There was no significant reduction in SHI or total MDADI scores. All patients maintained their QOL in the post-treatment time frame. There was no relationship between free-flap type and outcome. CONCLUSION: Total glossectomy with laryngeal sparing and free flap reconstruction results in significant reduction in objective functional measurements, but patients report stable functional and quality of life outcomes after treatment.

Coconut Oil as a Novel Approach to Managing Radiation-Induced Xerostomia: A Primary Feasibility Study.

BACKGROUND: Xerostomia is a common complication following radiation therapy for head and neck cancer (HNC), for which there is no single, universally accepted therapy. Coconut oil has been anecdotally suggested to provide relief for this complication. This study sought to examine the feasibility and effectiveness of coconut oil as a therapy for radiation-induced xerostomia. METHODS: A feasibility study was performed among 30 patients with xerostomia subsequent to radiation for HNC. Coconut oil samples were provided along with a protocol for use over a 2-week period and the option to continue if they found it beneficial. Patients were also instructed to keep diaries to document their patterns of use. The Xerostomia-related Quality of Life Scale (XeQOLS) was administered at baseline and 3-month follow-up. Descriptive methods were used to summarize patterns of coconut oil use and paired t-tests were used to assess changes in XeQOLS scores over time. RESULTS: The mean total duration of coconut oil use during the study period was 16 days (1-71). The average number of uses per day was 3 (1-5), with an average amount per use of 5 mL (1.2-8.5). Twelve patients (41.4%) continued coconut oil use beyond the advised period. There was no statistically significant difference in XeQOLS scores pre- and post-treatment. There were no adverse events during the study period. CONCLUSIONS: The use of coconut oil as a treatment strategy for xerostomia post-HNC radiation is feasible, inexpensive, and safe. This study demonstrates that there may be a group of HNC patients that benefit from its use.

The association of Bcl-xL and p53 expression with survival outcomes in oropharyngeal cancer.

BACKGROUND: The role of molecular biomarkers in oropharyngeal squamous cell carcinoma (OPSCC) has recently been increasingly recognized. There is conflicting evidence in the literature with regards to the prognostic value of p53 and Bcl-xL. OBJECTIVE: The purpose of this study was to investigate the association between p53 and Bcl-xL expression profiles and survival outcomes in OPSCC. METHODS: Patients diagnosed with OPSCC and treated with curative intent between 1998 and 2009 were included in the study. Patient demographics, disease, treatment, and oncologic outcomes were collected prospectively. A tissue microarray (TMA) from patients' biopsies or surgical specimens was retrospectively constructed. The expression levels of p53, Bcl-xL, and p16 were digitally quantified and correlated to patient survival outcomes. RESULTS: One hundred and sixty-six patients were included (mean age 56.7 years; standard deviation (SD) ± 10.0; 78% male). High expression of Bcl-xL (p= 0.04) was significantly associated with nodal disease at presentation, and decreased overall survival (OS) (p= 0.04). Combined expression of low Bcl-xL and low p53 conferred a survival advantage in non-smokers (p= 0.04). Multivariate analysis supported smoking and p16 status as independent prognosticators for OS. CONCLUSIONS: This study suggests that biomarker profiling using Bcl-xL and p53 levels may be of prognostic value in select patients with OPSCC.

Validation of a novel method for localization of parathyroid adenomas using SPECT/CT.

BACKGROUND: Accurate localization of parathyroid adenomas is of critical importance in surgical planning for minimally invasive parathyroidectomy. SPECT/CT is considered the investigation of choice but has limitations regarding localization of superior versus inferior adenomas. We proposed a novel method for localization using SPECT/CT by determining the anterior-posterior relationship of the adenoma to a horizontal line in the coronal plane through the tracheoesophageal groove. Our objective was to determine the accuracy, validity, and inter-rater reliability of this method. METHOD: This was a retrospective review of patients who underwent parathyroidectomy for a single adenoma between 2010-2017. SPECT/CT images were reviewed by two staff Otolaryngologists, a Radiologist, an Otolaryngology fellow and Otolaryngology resident. Results were compared using intra-operative report as the gold standard. Overall accuracy in determining superior/inferior and right/left adenomas was calculated, as well as Cohen's Kappa to determine agreement with operative report and inter-rater reliability. The performance was compared to that of the original radiology report. RESULTS: One hundred thirty patients met criteria and were included. Our method correctly identified the location of the adenoma in terms of both side and superior/inferior position in 80.4% [76 - 84%] of patients, which considerably outperformed the original radiology report at 48.5% [4-78%] accuracy. The agreement level between our method and operative report was high (Kappa=0.717 [0.691-0.743]), as was the inter-rater reliability (Kappa=0.706 [0.674-0.738]). CONCLUSION: We report a novel method for localization of parathyroid adenomas using SPECT/CT which outperforms standard radiology reporting. This tool can be used by surgeons and radiologists to better inform and plan for minimally invasive parathyroidectomy.

Temporary Frontal Paralysis Secondary to Blunt Trauma Frontal Sinus Fracture.

Frontal sinus fractures (FSF) are relatively uncommon and can be challenging for trauma surgeons to manage. Patients with FSF typically present with facial swelling, pain, and nasofrontal ecchymosis. Here we present a rare case of a patient with FSF and anterior table fracture where the main presenting symptom was bilateral frontal paralysis. We outline our management strategy and review the current literature in regard to management of FSF.

Is there a group of patients at greater risk for hematoma following thyroidectomy? A systematic review and meta-analysis.

OBJECTIVE: The purpose of this study was to perform a systematic review and meta-analysis to determine whether a difference exists in hematoma rates following thyroidectomy for any of the following subgroups of patients: Graves disease, toxic nodular goiter (TNG), and malignancy. STUDY DESIGN: Systematic review and meta-analysis. METHODS: A systematic literature search was performed for all relevant English and French language studies (1946-2015) using Ovid MEDLINE, EMBASE, and PubMed. Three authors independently extracted data and analyzed articles for quality using the Newcastle-Ottawa Quality Assessment Scale. Our primary outcome of interest was hematoma requiring re-operation. RESULTS: A total of 301 studies were screened, with 11 studies meeting the inclusion criteria. The results of our analysis demonstrated that Graves disease is the only indication for thyroidectomy that appears to have an increased risk of postoperative hematoma formation, pooled odds ratio = 1.58 (1.09-2.31); P = 0.02. Malignancy and TNG did not demonstrate significantly higher rates of postoperative hematoma formation. CONCLUSION: This study demonstrates that of patients undergoing thyroidectomy, Graves disease is the only indication in which patients are at increased risk of postoperative hematoma formation. This information may help guide future decisions regarding the implementation of outpatient thyroidectomy. LEVEL OF EVIDENCE: NA. Laryngoscope, 127:1483-1490, 2017.

Incidence of differentiated thyroid cancer in Canada by City of residence.

BACKGROUND: Thyroid cancer incidence in Canada is increased in high socioeconomic groups, and in urban compared with rural areas. The objective of this study was to analyze patterns in thyroid cancer incidence across Canada, particularly with respect to the major urban areas across the country, to identify whether there are any discrepancies in thyroid cancer incidence between Canadian cities. METHODS: Cases were drawn from the Canadian Cancer Registry. Demographic and socioeconomic information were extracted from the Canadian Census of Population data. We linked cases to income quintiles (InQs) by patients' postal codes, and categorized residence by census metropolitan area ((CMA), population >100,000). Within the Toronto CMA we further classified by census subdivision (CSD). RESULTS: There were a total of 33 CMAs across the country. After controlling for demographic and socio-economic factors, we found that the Toronto CMA had an IRR of thyroid cancer that was significantly higher than all other CMAs across the country. For 70% of CMAs and CAs across Canada, the IRR for thyroid cancer was less than half of the IRR for thyroid cancer in the Toronto CMA. As Toronto is one of the largest CMAs, we then subdivided the Toronto area into CSDs to examine how incidence of thyroid cancer varies within this large area. The Toronto City core was used as the reference category and all other areas were compared directly to it. In doing so, we found that a contiguous area of three CSDs North of Toronto had higher IRRs compared with the Toronto city core: Markham, Vaughan and Richmond Hill. CONCLUSIONS: After controlling for demographic and socioeconomic factors, we found that the Toronto CMA has the highest incidence of thyroid cancer nationwide. Several explanations could account for this discrepancy including increased detection due to increased access to imaging, differences in ethnicity or environmental exposures.
