Task force of the Brazilian Society of Otology - evaluation and management of peripheral facial palsy. Braz J Otorhinolaryngol 2024; 90:101374. [PMID: 38377729 PMCID: PMC10884764 DOI: 10.1016/j.bjorl.2023.101374] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 11/25/2023] [Indexed: 02/22/2024] Open
Abstract
OBJECTIVE To review key evidence-based recommendations for the diagnosis and treatment of peripheral facial palsy in children and adults. METHODS Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on peripheral facial palsy were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. RESULTS The topics were divided into 2 main parts: (1) Evaluation and diagnosis of facial palsy: electrophysiologic tests, idiopathic facial palsy, Ramsay Hunt syndrome, traumatic peripheral facial palsy, recurrent peripheral facial palsy, facial nerve tumors, and peripheral facial palsy in children; and (2) Rehabilitation procedures: surgical decompression of the facial nerve, facial nerve grafting, surgical treatment of long-term peripheral facial palsy, and non-surgical rehabilitation of the facial nerve. CONCLUSIONS Peripheral facial palsy is a condition of diverse etiology. Treatment should be individualized according to the cause of facial nerve dysfunction, but the literature presents better evidence-based recommendations for systemic corticosteroid therapy.

Position paper of diagnosis and treatment of post-extubation laryngitis in children: a multidisciplinary expert-based opinion. Braz J Otorhinolaryngol 2024; 90:101401. [PMID: 38428330 PMCID: PMC10912835 DOI: 10.1016/j.bjorl.2024.101401] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Accepted: 12/26/2023] [Indexed: 03/03/2024] Open
Abstract
OBJECTIVES To make recommendations on the diagnosis and treatment of post-extubation laryngitis (PEL) in children with or without other comorbidities. METHODS A three-iterative modified Delphi method was applied. Specialists were recruited representing pediatric otolaryngologists, pediatric and neonatal intensivists. Questions and statements approached topics encompassing definition, diagnosis, endoscopic airway evaluation, risk factors, comorbidities, management, and follow-up. A consensus was defined as a supermajority >70%. RESULTS Stridor was considered the most frequent symptom and airway endoscopy was recommended for definitive diagnosis. Gastroesophageal reflux and previous history of intubation were considered risk factors. Specific length of intubation did not achieve a consensus as a risk factor. Systemic corticosteroids should be part of the medical treatment and dexamethasone was the drug of choice. No consensus was achieved regarding dosage of corticosteroids, although endoscopic findings help defining dosage and length of treatment. Non-invasive ventilation, laryngeal rest, and use of comfort sedation scales were recommended. Indications for microlaryngoscopy and bronchoscopy under anesthesia were symptoms progression or failure to improve after the first 72-h of medical treatment post-extubation, after two failed extubations, and/or suspicion of severe lesions on flexible fiberoptic laryngoscopy. CONCLUSIONS Management of post-extubation laryngitis is challenging and can be facilitated by a multidisciplinary approach. Airway endoscopy is mandatory and impacts decision-making, although there is no consensus regarding dosage and length of treatment.

Abstract
BACKGROUND Clinical evaluation of swallowing provides important clinical information but is limited in detecting penetration, aspiration, and pharyngeal residue in patients with suspected dysphagia. Although this is an old problem, there remains limited access to low-cost methods to evaluate swallowing safety and efficiency. PURPOSE The purpose of this technical report is to describe the experience of a single center that recently began using a wireless Wi-Fi intraoral camera for transoral endoscopic procedures as an adjunct to clinical swallowing evaluation. We describe the theoretical structure of this new clinical evaluation proposal. We present descriptive findings on its diagnostic performance in relation to videofluoroscopic swallowing study as the gold standard in a cohort of seven patients with dysphagia following head and neck cancer. We provide quantitative data on intra- and interrater reliability. Furthermore, this report discusses how this technology can be applied in the clinical practice of professionals who treat patients with dysphagia and provides directions for future research. CONCLUSIONS This preliminary retrospective study suggests that intraoral cameras can reveal the accumulated oropharyngeal secretions and postswallow pharyngolaryngeal residue in patients with suspected dysphagia. Future large-scale studies focusing on validating and exploring this contemporary low-cost technology as part of a clinical swallowing evaluation are warranted.

Abstract
Merkel cell carcinoma (MCC) is an aggressive and rare cutaneous neuroendocrine carcinoma that predominantly affects the sun-damaged skin of the head and neck region, extremities, and trunk of older white individuals. Microscopically, MCC is characterized by nests or sheets of uniform small round blue cells with scant cytoplasm, granular nuclei with a salt-and-pepper chromatin pattern, high proliferative activity, and occasional necrosis. They are usually positive for epithelial and neuroendocrine markers, particularly for cytokeratin 20 and AE1/AE3 in a paranuclear dot-like staining. We herein contribute by reporting a case of MCC affecting the auricular pavilion of a 66-year-old female patient from Campinas, Brazil. Additionally, a review of the current literature is also included to analyze all the cases that have been reported in the English-language literature, totalizing 27 cases of MCC on the external ear. The 5-year overall survival rate for individuals with localized MCC is 50% and the most common treatment choice is the combination of surgery with adjuvant radiotherapy and sentinel lymph node biopsy.

Abstract
INTRODUCTION Neuroendocrine carcinoma is a rare form of cancer originating from neuroendocrine cells, with the lungs being the most common site of occurrence. These tumors have the potential to metastasize to the head and neck region. CASE REPORT A 57-year-old man, with a smoking history of 74 pack-years, presented with complaints of hoarseness, dry cough, dysphagia, and significant weight loss over a two-month period. During oral examination, a submucosal nodule in the left palatine tonsil was discovered. Histological analysis confirmed a poorly differentiated tumor consisting of large cells with nuclear pleomorphism and abundant cytoplasm. The tumor tested positive for CD56, chromogranin, synaptophysin, and EMA. Further imaging revealed a substantial endobronchial lesion in the upper segment of the left lower lobe. Biopsy results from this lesion were morphologically and immunohistochemically consistent with those from the oral lesion. A diagnosis of metastatic large-cell neuroendocrine carcinoma originating from the lung and involving the oral mucosa was established. CONCLUSION This case highlights the metastatic potential of pulmonary neuroendocrine carcinoma and its occurrence in atypical dissemination sites. Additionally, our findings underscore the importance of early detection of oral metastases to ensure accurate diagnosis and expedite appropriate treatment.

Abstract
A 54-year-old male patient complained of nasal obstruction and epistaxis for 2 years, with worsening of the symptoms in the preceding year. Physical examination revealed a friable, irregular mass, with yellowish secretion, in the left nasal fossa. Magnetic resonance imaging revealed an expansive lesion in the left nasal cavity, extending into the nasopharynx, ethmoid, right nasal cavity, and cortical bone of the hard palate. An incisional biopsy was then performed. Morphologically, a cellular malignant proliferation with a solid basaloid appearance admixed with adenoid cystic-like areas was observed. Immunohistochemistry revealed positivity for AE1/AE3, CK7, p63, and calponin, with focal labeling for CD117 and α-SMA. p16 had diffuse cytoplasmic and nuclear positivity. Ki-67 index was >80%. Given the morphological and immunohistochemical aspects, the diagnosis was conclusive for HPV-related multiphenotypic sinonasal carcinoma. The tumor was considered irresectable, and the patient was submitted to induction chemotherapy with docetaxel, cisplatin, and infusional 5-fluorouracil, with significant regression after therapy, followed by chemoradiotherapy with carboplatin, without limiting toxicities. The patient is currently under regular follow-up, with complete clinical and radiological response. To date, there are no reports in the literature of induction chemotherapy use or its complete therapeutic responsiveness related to this lesion. A brief literature review was included with the main epidemiological, clinical, therapeutic, and prognostic aspects regarding the 85 cases reported in the literature, including ours.

Abstract
According to an extensive database, the Objective is to compare surgical versus non-surgical treatment through Propensity Score (PS) for patients with Oropharyngeal Squamous Cell Carcinoma (OPSCC). METHODS We retrospectively evaluated epidemiological data from 8075 patients with OPSCC diagnosed between 2004 and 2014 and used PS matching to analyze possible prognostic factors for its outcomes with regression analyses. RESULTS Cox multiple regression analysis to study survival after PS matching shows that type of treatment was associated with death with a hazard ratio of 1.753 (p<0.05) of non-surgical treatment. However, it was not associated with recurrence (p>0.05). In the surgical treatment group, overall survival was 79.9% at one year, 36.4% at five years, and 20.5% at ten years. Disease-free survival was 90.1%, 64.8%, and 56.0% at 1, 5, and 10-years, respectively. In the non-surgical treatment group, overall survival was 60.6% at one year, 21.8% at five years, and 12.7% at ten years. Disease-free survival was 90.8%, 67.2%, and 57.8% at 1, 5, and 10-years, respectively. CONCLUSION Patients in the surgical treatment group had better outcomes related to survival. Recurrence is associated with the survival of OPSCC cancer. Recurrence-free survival is similar to both treatments. LEVEL OF EVIDENCE 2C.

Abstract
OBJECTIVE To review the literature on the diagnosis and treatment of vestibular schwannoma. METHODS Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on vestibular schwannoma were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. RESULTS The topics were divided into 2 parts: (1) Diagnosis - audiologic, electrophysiologic tests, and imaging; (2) Treatment - wait and scan protocols, surgery, radiosurgery/radiotherapy, and systemic therapy. CONCLUSIONS Decision making in VS treatment has become more challenging. MRI can diagnose increasingly smaller tumors, which has disastrous consequences for the patients and their families. It is important to develop an individualized approach for each case, which highly depends on the experience of each surgical team.

Abstract
OBJECTIVES To review and provide evidence-based recommendations for the diagnosis and treatment of otosclerosis. METHODS Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on otosclerosis were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. RESULTS The topics were divided into 2 parts: 1) Diagnosis - audiologic and radiologic; 2) Treatment - hearing AIDS, pharmacological therapy, stapes surgery, and implantable devices - bone-anchored devices, active middle ear implants, and Cochlear Implants (CI). CONCLUSIONS The pathophysiology of otosclerosis has not yet been fully elucidated, but environmental factors and unidentified genes are likely to play a significant role in it. Women with otosclerosis are not at increased risk of worsening clinical condition due to the use of contraceptives or during pregnancy. Drug treatment has shown little benefit. If the patient does not want to undergo stapedotomy, the use of hearing aids is well indicated. Implantable systems should be indicated only in rare cases, and the CI should be indicated in cases of profound deafness.

Abstract
OBJECTIVE To analyze, by means of a systematic review and meta-analysis, the proportion of patients with Meniere's disease who have altered caloric test and vHIT, as well as to determine the prevalence of altered caloric test and normal vHIT dissociation in the diagnosis of Meniere's disease. METHODS The literature search had no restriction regarding the period of publication on the following indexed data platforms: PubMed, PubMed PMC, BVS-Bireme, Web of Science, Embase and Cochrane Library. Articles that evaluated patients with Meniere's disease who underwent caloric test and vHIT were included. Two researchers independently conducted the analysis of the articles, promoting the selection and capture of data, following the recommendations of the PRISMA method, and complying with the criteria for articles inclusion and exclusion defined in the research protocol. In case of disagreement during the selection process, a third researcher was included for analysis. RESULTS From a total of 427 initial studies, the researchers selected 12 articles, published between 2014 and 2021, with a total of 708 patients evaluated, with a mean age of 52.72 years old. The prevalence of patients with Meniere's disease with altered caloric reflex test was 64% (95% CI 57%‒71%), while the prevalence of altered vHIT was only 28% (95% CI 16%-40%). The prevalence of the altered caloric test + normal vHIT dissociation was 47% (95% CI 37%-57%). CONCLUSION The video head impulse test and the caloric test are valuable tools for vestibular assessment. The dissociation of findings between these two tests in patients with Meniere's disease was more prevalent in this meta-analysis and may be a result of the tonotopy of specialized hair cells in the ampullary crest. The prevalence of altered caloric test was 64% and anormal vHIT was 28%. The dissociation caloric asymmetry and normal vHIT was observed in 47% of the patients. LEVEL OF EVIDENCE: 1

Abstract
OBJECTIVE To analyze the proteomic profile of salivary pleomorphic adenoma (PA) and carcinoma ex pleomorphic adenoma (CXPA) samples and correlate them with the malignant transformation of the PA. MATERIALS AND METHODS Thirty samples (10 PA, 16 CXPA, and 4 residual PA) were microdissected and submitted to liquid chromatography-tandem mass spectrometry (LC-MS/MS). The proteomic data and protein identification were analyzed through LC-MS/MS spectra using the MaxQuant software. RESULTS The proteomic analysis identified and quantified a total of 240 proteins in which 135 were found in PA, residual PA, and CXPA. The shared proteins were divided into six subgroups, and the proteins that showed statistically significant differences (p > 0.05) and fold-change > or <2.5 in one subgroup to another subgroup were included. Seven proteins (Apolipoprotein A-I-APOA1, haptoglobin-HP, protein of the synaptonemal complex 1-SYCP1, anion transport protein of band 3-SLC4A1, subunit μ1 of AP-1 complex-AP1M1, beta subunit of hemoglobin-HBB, and dermcidin-DCD) were classified as potential protein signatures, being HP, AP1M1, and HBB with higher abundance for PA to residual PA, APOA1 with higher abundance for PA to CXPA, SLC4A1 with lower abundance in the PA to CXPA, SYCP1with lower abundance for residual PA to CXPA, and DCD with higher abundance in the CXPA with epithelial differentiation to myoepithelial differentiation. CONCLUSIONS In this work, we demonstrated the comparative proteomic profiling of PA, residual PA, and CXPA, and seven were proposed as protein signatures, some of which may be associated with the malignant phenotype acquisition.

Abstract
BACKGROUND The most common current hearing protection devices (HPDs) on the market include earplugs and earmuffs. A variety of materials can be used to manufacture these devices, and each offers a level of noise attenuation that is informed by the manufacturer although it does not always correspond to the attenuation observed in real-world use. OBJECTIVE To evaluate the noise attenuation of HPDs available to workers exposed to noise. METHODS The most relevant studies originally published in English, Portuguese, or Spanish that investigated the noise attenuation effectiveness of HPDs used by workers exposed to noise were analyzed. The following electronic databases were searched by 2 independent reviewers for studies published from 1999 to 2019: MEDLINE (PubMed), Scopus, Web of Science, EMBASE, Cochrane Library (OVID), ProQuest, and BVS-Bireme. Different combinations of the following search terms (MeSH terms) were used for all databases: "Hearing Loss, Noise-Induced", "Ear Protective Devices" (Efficacy OR Effectiveness)", "Noise, Occupational". RESULTS The search strategy yielded a total of 326 potentially relevant studies. After the removal of duplicates, 156 remained for the screening of titles and abstracts. After reviewing titles and abstracts, 46 studies were selected for full-text reading. Of these, six were included in this systematic review. CONCLUSION Hearing protection devices reduced the noise exposure and were effective in all included studies in different countries, types of activity, and sound pressure exposure.

Abstract
OBJECTIVE Oral Squamous Cell Carcinoma (OSCC) is conventionally treated by surgical resection, and positive surgical margins strongly increase local recurrence and decrease survival. This study aimed to evaluate whether a Three-Dimensional Segmentation (3DS) image of OSCC confers advantage over Multiplanar Reconstruction (MPR) of OSCC using images of computed tomography scan in surgical planning of tumor resection. METHODS Twenty-six patients with locally advanced OSCC had tumor morphology and dimensions evaluated by MPR images, 3DS images, and Surgical Pathology Specimen (SPS) analyses (gold standard). OSCC resection was performed with curative intent using only MPR images. RESULTS OSCC morphology was more accurately assessed by 3DS than by MPR images. Similar OSCC volumes and dimensions were obtained when MPR images, 3DS images and SPS measurements were considered. Nevertheless, there was a strong correlation between the OSCC longest axis measured by 3DS and SPS analyses (ICC = 0.82; 95% CI 0.59‒0.92), whereas only a moderate correlation was observed between the longest axis of OSCC measured by MPR images and SPS analyses (ICC = 0.51; 95% CI 0.09‒0.78). Taking only SPS with positive margins into account, MPR images and 3DS images underestimated the tumor's longest axis in eight out of 11 (72.7%) and 5 out of the 11 (45.5%) cases, respectively. CONCLUSION Our data present preliminary evidence that 3DS model represents a useful tool for surgical planning of OSCC resection, but confirmation in a larger cohort of patients is required. LEVEL OF EVIDENCE Laboratory study.

[PMID: 36064816 DOI: 10.1016/j.bjorl.2022.07.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 06/20/2022] [Accepted: 07/22/2022] [Indexed: 12/14/2022] Open
Abstract
OBJECTIVE To descriptively analyze the epidemiological data, clinical stage, and outcomes of oropharyngeal squamous cell carcinoma in the state of São Paulo, Brazil, and to estimate the influence of clinical stage and treatment type on overall and disease-free survival. METHODS We retrospectively analyzed epidemiological data from the São Paulo Cancer Center Foundation database relative to patients with oropharyngeal squamous cell carcinoma diagnosed between 2004 and 2014 in the state of São Paulo. Univariate and multivariate Cox regression analyses were performed to assess factors associated with the outcomes. A forward stepwise selection procedure was used. Survival curves were estimated by the Kaplan-Meier method and compared by the Gehan-Breslow-Wilcoxon test. RESULTS A total of 8075 individuals with oropharyngeal squamous cell carcinoma were identified. Of these, 86.3% were diagnosed at an advanced stage and 13.7% at an early stage. Only 27.2% of patients were treated surgically, whereas 57.5% were treated medically. Patients undergoing surgery had longer overall survival than those receiving medical treatment in both early- and advanced-stage oropharyngeal squamous cell carcinoma. However, there was no significant difference in disease-free survival between surgical and medical treatment. CONCLUSION No significant difference in disease-free survival between medical and surgical treatment suggests similar complete remission rates with both approaches. Patients receiving medical treatment had shorter overall survival, which may be due to complications from chemotherapy and radiotherapy. However, we cannot confirm this relationship based on the data provided by the São Paulo Cancer Center Foundation. Prospective studies are warranted to assess whether the lower overall survival rate in patients receiving medical treatment is secondary to complications from chemotherapy and radiotherapy. LEVEL OF EVIDENCE 2C.

Abstract
BACKGROUND This study aimed to evaluate the accuracy and oncological results of sentinel lymph node biopsy in patients with early lip and oral cavity squamous cell carcinoma (SCC) in a real-world scenario. METHODS Retrospective study including seven Brazilian centers. RESULTS Four-hundred and seven cN0 patients were accrued for 20 years. The rate of occult metastasis was 23.1% and 22 patients (5.4%) had regional failure. We found, for 5 years of follow-up, 85.3% of regional recurrence-free survival; 77.1% of disease-free survival; 73.7% of overall survival; and 86.7% of disease-specific survival. The rate of false-negative cases was 5.4%. CONCLUSION In a real-world scenario, sentinel lymph node biopsy for patients with SCC of the lip and oral cavity proved feasible in different settings and to be oncologically safe, with similar rates of occult lymph node metastasis and false-negative cases, when compared to elective neck dissection, and with similar long-term survival to that reported historically.

Abstract
PURPOSE Translate into Brazilian Portuguese and culturally adapt the component scores definition from the Modified Barium Swallow Impairment Profile - MBSImP videofluoroscopy protocol. METHODS This study was conducted based on international guidelines for creation, translation and transcultural adaptation according to domestic publications for the validation of international speech-language pathology tests. A specialist committee was convened with two otorhinolaryngologists and three speech-language pathologists familiar with videofluoroscopy examinations. Translation into Brazilian Portuguese was carried out by two otorhinolaryngologists with subsequent back translation performed independently by two U.S.-born translators. The final Brazilian Portuguese version was written by speech-language pathologists after revision of translations and back translations resolved semantic, idiomatic, conceptual, linguistic and contextual inconsistencies. This version was tested by committee members, who assessed subjects with no disease, with head and neck cancer and with mild cognitive impairment. RESULTS Translation of the component scores definition from MBSImP was performed independently and translators agreed on a final version. The MBSImP protocol was renamed "Martin-Harris scale for swallowing videofluoroscopy". Some terms were adapted for the final Brazilian Portuguese version. Use of the translated protocol did not reveal any deviations from the original. CONCLUSION Translation of the MBSImP fragment into Brazilian Portuguese was consistent with the original version. Approval from specialist committee members refined the protocol adaptation, allowing precise concepts to be accurately translated.

Does the video head impulse test replace caloric testing in the assessment of patients with chronic dizziness? A systematic review and meta-analysis. Braz J Otorhinolaryngol 2021; 87:733-741. [PMID: 33642214 PMCID: PMC9422509 DOI: 10.1016/j.bjorl.2021.01.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Revised: 12/06/2020] [Accepted: 01/06/2021] [Indexed: 11/09/2022] Open
Abstract
Introduction Caloric testing is the most frequently used test to assess peripheral vestibular function since the beginning of the 20th century. However, the video head impulse test, vHIT, has gained prominence in the field of neurotology, as it is a faster examination, easier to perform and less uncomfortable for the patient. Objective To compare, through systematic review and meta-analysis, the proportion of altered cases between vHIT tests and caloric testing in patients with chronic dizziness, in addition to assessing the sensitivity and specificity of vHIT, with caloric testing as the gold standard. Methods The literature search was carried out in the PubMed, Scopus, BVS-Bireme, Web of Science, Embase, Cochrane and ProQuest indexed databases, with no restrictions regarding the publication period. All articles that contained the results of the two tests were included in the evaluation of patients with dizziness. Two researchers independently conducted data selection and extraction from the studies, strictly following the inclusion and exclusion criteria defined in the research protocol. In case of disagreement during the selection, a discussion was carried out with a third evaluator. Results Eleven of the 1293 initial articles met the eligibility criteria and were analyzed. 2670 patients were evaluated, of which 1112 (41.6%) were males and 1558 (58.4%) females, with a mean age of 51.6 years. The proportion of altered results in the vHIT was 21% (95%CI 9% –33%), and 55% in the caloric testing (95%CI 43% –67%). Conclusion The vHIT does not substitute for caloric testing. The tests are complementary in assessing the patient with dizziness, as they describe the tonotopy of the ampullary crest at different frequency ranges of stimulation. In chronic cases, the vHIT has a low sensitivity and high diagnostic specificity in comparison to caloric testing.

Abstract
PURPOSE To propose a normalization model of a posturography platform in adults without changes in body balance, through descriptive analysis by age group and sex. METHODS Cross-sectional observational study. Adults, with no changes in body balance and no vestibular complaints were submitted to 6 sensory conditions on the Horus® posturography platform. The following variables were analyzed: stability limit area and confidence ellipse area, trajectory length and average velocity for each condition tested. The variables were analyzed by age group and sex. The equilibrium score, the sensory integration test and the equilibrium index were calculated on the conditions. RESULTS Sixty-one subjects (38.3%) and 23 (37.7%) were male, 40 (65.57%) between the ages of 20 and 40 and 21 (34.43). %) between 41 and 59 years. The area of the stability limit and pressure center variables for 6 sensory conditions tested - confidence ellipse area, trajectory length, total mean velocity and confidence ellipse ratio by the area of the stability limit were described. There was a statistically significant difference in the comparison between the area of the stability limit between sexes and between age groups, being a higher value in males and in younger patients. Regarding the analysis of the variables by each condition, there was no difference of results between the sexes and age groups. CONCLUSION Subjects of different sexes and age groups should be considered separately only in the analysis of the stability limit.

Is it necessary to perform occupational audiometric testing at 6-months of employment? Braz J Otorhinolaryngol 2021; 88:891-895. [PMID: 33663974 PMCID: PMC9615527 DOI: 10.1016/j.bjorl.2020.12.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Revised: 11/18/2020] [Accepted: 12/08/2020] [Indexed: 12/01/2022] Open
Abstract
Introduction Current Brazilian legislation requires that all workers exposed to noise are to be given an audiogram upon hiring, after 6 months of employment (first periodic test), and annually after the first periodic test. In other countries, the regulations of hearing conservation programs do not include the requirement for audiometric testing at 6 months of employment, but only annually. There is no evidence that the periodicity adopted by Brazilian legislation is the most appropriate. Objective The present study aimed to evaluate the first 3 occupational audiometric tests of workers exposed to noise. Methods Historical cohort study with cross-sectional analysis. Participants were all male metallurgy workers aged up to 40 years. The first 3 audiograms of each worker were analyzed: pre-employment audiometric test, periodic audiometric test 1, and periodic audiometric test 2. For each worker, mean frequency thresholds were calculated at 3, 4, and 6 kHz in the left and right ears for each test. Statistical analysis was performed using the nonparametric Wilcoxon test. Results A total of 988 workers were included. There was a significant difference in auditory thresholds between the pre-employment test and the 2 subsequent periodic tests for the right and left ears. There was no significant difference between Test1 and Test2 in either ear. Conclusion Given the lack of difference between the first 2 periodic tests, we believe that they could be merged into a single test, i.e., first periodic audiometric testing could be performed at 12 months of employment without compromising workers’ health.

Abstract
Radiotherapy and cisplatin lead to cell killing in head and neck squamous cell carcinoma patients, but adverse events and response to treatment are not the same in patients with similar clinicopathological aspects. The aim of this prospective study was to evaluate the roles of TP53 c.215G > C, FAS c.-671A > G, FAS c.-1378G > A, FASL c.-844 C > T, CASP3 c.-1191A > G, and CASP3 c.-182-247G > T single nucleotide variants in toxicity, response rate, and survival of cisplatin chemoradiation-treated head and neck squamous cell carcinoma patients. Genomic DNA was analyzed by polymerase chain reaction for genotyping. Differences between groups of patients were analyzed by chi-square test or Fisher's exact test, multiple logistic regression analysis, and Cox hazards model. One hundred nine patients with head and neck squamous cell carcinoma were enrolled in study. All patients were smokers and/or alcoholics. Patients with FAS c.-671GG genotype, FAS c.-671AG or GG genotype, and FASL c.-844CC genotype had 5.52 (95% confidence interval (CI): 1.42-21.43), 4.03 (95% CI: 1.51-10.79), and 5.77 (95% CI: 1.23-27.04) more chances of presenting chemoradiation-related anemia of grades 2-4, lymphopenia of grade 3 or 4, and ototoxicity of all grades, respectively, than those with the remaining genotypes. FAS c.-671GG genotype was also seen as an independent predictor of shorter event-free survival (hazard ratio (HR): 2.05; P = 0.007) and overall survival (HR: 1.83; P = 0.02) in our head and neck squamous cell carcinoma patients. These findings present, for the first time, preliminary evidence that inherited abnormalities in apoptosis pathway, related to FAS c.-671A > G and FASL c.-844 C > T single nucleotide variants, can alter toxicity and survival of tobacco- and alcohol-related head and neck squamous cell carcinoma patients homogeneously treated with cisplatin chemoradiation.

Abstract
Introduction We are facing a pandemic with a great impact worldwide, as a result of the rapid spread of the novel coronavirus (COVID-19). The medical community is still getting to know behavior of this virus and the consequences from a population point of view. All this knowledge is extremely dynamic, so some behaviors are still not well established. Otorhinolaryngologists have a central role in the management of this situation, in which they must assess the patient, avoid contamination to and by health professionals and other patients. Thus, the recommendations of the Brazilian Association of Otorhinolaryngology and Cervical-Facial Surgery (ABORL-CCF) have the main objective of reducing the spread of the new coronavirus during otorhinolaryngological care and assisting in the management of these patients. Methods Review of the main recommendations of national and international scientific societies, decisions by government agencies and class councils. The topics will be related to the general aspects of COVID-19, personal protective equipment, care in patient assistance, endoscopic exam routines and the management of sinonasal, otological and pediatric evaluations related to COVID-19. Results The use of personal protective equipment is considered crucial in routine ENT care. We recommend postponing appointments, exams and elective surgeries to reduce the spread of COVID-19. Similarly, we recommend changing routines in several areas of otolaryngology. Additionally, guidance is provided on the use of telemedicine resources during the pandemic period. Conclusions We are still at the beginning of the COVID-19 pandemic and scientific evidence is still scarce and incomplete, so these ABORL-CCF recommendations for otorhinolaryngologists may be updated based on new knowledge and the pattern of the new coronavirus spread.

Abstract
Spindle cell carcinoma (SpCC) is a rare tumor, which occurs in upper respiratory tract, mainly in larynx. This study aimed to review the clinical and pathological characteristics for diagnosis and prognosis. Retrospective cohort study. All patients with SpCC in upper respiratory tract treated for curative intent was included. All patients were reviewed in search of epithelial component and immunohistochemistry when not found. It was evaluated rate of recurrence and disease-free survival with univariate and multivariate analysis with Kaplan Meier and Cox Regression model adjusted to propensity score indexes (PSI) according to age, gender, site of tumor, stage, surgical treatment, status of margins of surgical resection, lymphatic invasion. There were 16 cases of SpCC.31% were diagnosed with light microscopy and others with immunohistochemistry for epithelial marker. Disease-free survival was higher in early stage disease in univariate and multivariate analysis, as the main prognostic factor. Surgical treatment increases in 2.54 the rate of survival. The SpCC is a rare tumor considered a highly malignant variant of squamous cell carcinoma. It has male predominance and tobacco use as risk factors. Its treatment should follow the same recommendations for squamous cell carcinoma, with surgery as the maintain treatment. Immunohistochemistry is an adjuvant important tool for diagnosis of SpCC.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is treated with cisplatin (CDDP) and radiotherapy (RT), and distinct results are observed among patients with similar clinicopathological aspects. This prospective study aimed to investigate whether MLH1 c.-93G>A (rs1800734), MSH2 c.211+9C>G (rs2303426), MSH3 c.3133G>A (rs26279), EXO1 c.1765G>A (rs1047840), and EXO1 c.2270C>T (rs9350) single nucleotide polymorphisms (SNPs) of the mismatch repair (MMR) pathway change side effects and response rate of 90 HNSCC patients treated with CDDP and RT. DNA from peripheral blood was analyzed by PCR-based methods to obtain genotypes. It was observed 4.27-fold and 4.69-fold increased risks of presenting pronounced nephrotoxicity with treatment in patients with MSH3 GG and EXO1 rs9350 CC genotypes compared with patients with GA or AA and CT or TT genotypes, respectively. MSH3 GG or GA and GT haplotype of EXO1 rs1047840 and rs9350 SNPs conferred to patients 10.29 and 4.00 more chances of presenting pronounced ototoxicity after treatment than MSH3 AA genotype and other EXO1 haplotypes, respectively. Patients with EXO1 rs1047840 GA or AA genotype and AC haplotype of EXO1 rs1047840 and rs9350 SNPs had both 9.55-fold increased risks of achieving partial response or stable disease instead of complete remission after treatment than patients with EXO1 GG genotype and other EXO1 haplotypes, respectively. For the first time, our data show preliminary indication that inherited alterations of DNA MMR pathway, related to MSH3 rs26279, EXO1 rs1047840 and EXO1 rs9350 SNPs, modify toxicity and response to chemoradiation in HNSCC, and may contribute to future personalized treatment of patients.

This study aimed to investigate the associations of XPC c.2815A>C, XPD c.934G>A and c.2251A>C, XPF c.2505T>C and ERCC1 c.354C>T single nucleotide polymorphisms (SNPs) of nucleotide excision repair pathway in outcome of head and neck squamous cell carcinoma (HNSCC) patients treated with cisplatin (CDDP) chemoradiation. Patients with XPC c.2815AC or CC and XPD c.934GA or AA genotypes had 0.20 and 0.38 less chances of presenting moderate/severe ototoxicity and nausea, respectively. Patients with XPD c.934AA and c.2251AC or CC genotypes had 8.64, 12.29 and 3.55 more chances of achieving complete response (CR), consistent ototoxicity and nephrotoxicity, respectively. AA haplotype of XPD and ACT haplotype of XPD and ERCC1 SNPs were associated with 9.30 and 3.41 more chances of achieving CR and consistent nephrotoxicity, respectively. At 24 months of follow-up, patients with XPD c.934AA genotype presented lower progression-free survival and overall survival in Kaplan-Meier estimates, and differences between groups remained the same in univariate Cox analysis. Patients with XPD c.934AA genotype had 2.13 and 2.04 more risks of presenting tumor progression and death than others in multivariate Cox analysis. Our data present preliminary evidence that XPC c.2815A>C, XPD c.934G>A and c.2251A>C, and ERCC1 c.354C>T SNPs alter outcome of HNSCC patients treated with CDDP chemoradiation.

Histologic correlation of VEGF and COX-2 expression with tumor size in squamous cell carcinoma of the larynx and hypopharynx. EAR, NOSE & THROAT JOURNAL 2017; 96:176-182.

Abstract
The prognosis and survival of patients with laryngeal and hypopharyngeal squamous cell carcinoma (SCC) are related to the clinical staging. Tumor growth and metastasis are closely related to angiogenesis. Vascular endothelial growth factor (VEGF) and cyclooxygenase 2 (COX-2) are intimately related to the angiogenic process in which the blood supply required for neoplastic evolution is ensured. Considering the contributions of VEGF and COX-2 to the formation, growth, and progression of primary tumors, as well as their metastasis, it has been thought that the expression of these two factors might be related to the size and/or aggressiveness of laryngeal and hypopharyngeal cancer. To test that theory, we conducted a retrospective study to evaluate the expression of VEGF and COX-2 markers in archived specimens of SCC of the larynx and hypopharynx to correlate their expression with tumor size. These specimens had been obtained from 35 patients-31 men and 4 women, aged 37 to 75 years (mean: 57)-who had been treated for laryngeal or hypopharyngeal SCC at our tertiary care university hospital over a period of 15 years. Immunohistochemical analyses were performed with avidin-biotin-peroxidase staining for VEGF and COX-2 antibodies. The degree of VEGF and COX-2 expression was based on the German scale of immunoreactivity. Specimens were separated into groups based on the intensity of expression (none/low and moderate/strong) and tumor size (TNM categories T1/T2 and T3/T4). A total of 7 patients exhibited moderate or strong VEGF expression (3 from the T1/T2 group and 4 from the T3/T4 group), and 17 patients demonstrated moderate or strong COX-2 expression (8 from the T1/T2 group and 9 from the T3/T4 group). We found no statistically significant relationship between tumor size and either VEGF or COX-2 expression. Our study demonstrated that despite the intrinsic connection between and VEGF and COX-2, neither appears to be related to the size of the SCCs of the larynx or hypopharynx. Other factors must be involved in the pathogenesis and progression of this disease, and further studies are needed to identify them.

Partial laryngectomy in glottic cancer: complications and oncological results. Braz J Otorhinolaryngol 2016; 82:275-80. [PMID: 26614047 PMCID: PMC9444659 DOI: 10.1016/j.bjorl.2015.05.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2014] [Accepted: 05/05/2015] [Indexed: 11/10/2022] Open
Abstract
Introduction Most patients with laryngeal carcinoma present tumors in the glottis that can be treated by different treatment modalities. Some authors consider open partial laryngectomy as obsolete, while others still deem this as a viable and cost-efficient option. Objectives To compare the oncological and functional results of a series of patients undergoing partial laryngectomy vs. external radiotherapy for the treatment of glottic cancer. Methods Historical cohort study with a series of glottic carcinoma patients undergoing partial laryngectomy or external radiotherapy during a period of ten years. Results Sixty-two patients with glottic carcinoma were included. Group A comprised those submitted to partial laryngectomy (n = 30), and Group B, those who underwent radiotherapy (n = 32). They were homogeneous in the comparison of mean age, 56.4 vs. 60.4 years (p = 0.12) and distribution in pathological stage (p = 0.91). With regard to oncological outcome, there were no differences in distant metastasis rates, or second primary tumor between groups (p = 1.0), as well as in disease-free time, laryngeal rescue-free time, and overall five-year survival. Severe complication rates were also similar between groups. Conclusion Open partial laryngectomy had complication rates and oncological results similar to those of radiotherapy for patients with glottic carcinomas and should still be considered among the main available therapeutic options.

Abstract
INTRODUCTION Squamous cell carcinoma is the most common neoplasm of the larynx, and its evolution depends on tumor staging. Vascular endothelial growth factor is a marker of angiogenesis, and its expression may be related to increased tumor aggressiveness, as evidenced by the presence of cervical lymphatic metastases. OBJECTIVES To evaluate the expression of the vascular endothelial growth factor marker in non-glottic advanced squamous cell carcinoma of the larynx (T3/T4) and correlate it with the presence of cervical lymph node metastases. METHODS Retrospective clinical study and immunohistochemical analysis of vascular endothelial growth factor through the German scale of immunoreactivity in products of non-glottic squamous cell carcinomas. RESULTS This study analyzed 15 cases of advanced non-glottic laryngeal tumors (T3/T4), four of which exhibited cervical lymphatic metastases. There was no correlation between vascular endothelial growth factor expression and the presence of cervical metastases. CONCLUSION Although vascular endothelial growth factor was expressed in a few cases, there was no correlation with the spread of cervical lymph metastases.

Abstract
Introduction Treatments for patients with laryngeal cancer often have an impact on physical, social, and psychological functions. Objective To evaluate quality of life and voice in patients treated for advanced laryngeal cancer through surgery or exclusive chemoradiation. Methods Retrospective cohort study with 30 patients free from disease: ten total laryngectomy patients without production of esophageal speech (ES); ten total laryngectomy patients with tracheoesophageal speech (TES), and ten with laryngeal speech. Quality of life was measured by SF-36, Voice-Related Quality of Life (V-RQOL), and Voice Handicap Index (VHI) protocols, applied on the same day. Results The SF-36 showed that patients who received exclusive chemoradiotherapy had better quality of life than the TES and ES groups. The V-RQOL showed that the voice-related quality of life was lower in the ES group. In the VHI, the ES group showed higher scores for overall, emotional, functional, and organic VHI. Discussion Quality of life and voice in patients treated with chemoradiotherapy was better than in patients treated surgically. Conclusion The type of medical treatment used in patients with laryngeal cancer can bring changes in quality of life and voice.

Abstract
INTRODUCTION The recently-proposed Bethesda reporting system has offered clinical recommendations for each category of reported thyroid cytology, including repeated fine-needle aspiration (FNA) for non-diagnostic and atypia/follicular lesions of undetermined significance, but there are no sound indications for repeated examination after an initial benign exam. OBJECTIVE To investigate the clinical validity of repeated FNA in the management of patients with thyroid nodules. METHOD The present study evaluated 412 consecutive patients who had repeated aspiration biopsies of thyroid nodules after an initial non-diagnostic, atypia/follicular lesion of undetermined significance, or benign cytology. RESULTS The majority of patients were female (93.5%) ranging from 13 to 83 years. Non-diagnostic cytology was the most common indication for a repeated examination in 237 patients (57.5%), followed by benign (36.8%), and A/FLUS (5.6%) cytology. A repeated examination altered the initial diagnosis in 70.5% and 78.3% of the non-diagnostic and A/FLUS patients, respectively, whereas only 28.9% of patients with a benign cytology presented with a different diagnosis on a sequential FNA. CONCLUSIONS Repeat FNA is a valuable procedure in cases with initial non-diagnostic or A/FLUS cytology, but its routine use for patients with an initial benign examination appears to not increase the expected likelihood of a malignant finding.

Abstract
Introduction Squamous cell carcinoma is the most common neoplasm of the larynx and glottis, and its prognosis depends on the size of the lesion, level of local invasion, cervical lymphatic spread, and presence of distant metastases. Ki-67 (MKI67) is a protein present in the core, whose function is related to cell proliferation. Aim To evaluate the expression of marker Ki-67 in squamous cell carcinoma of the larynx and glottis and its correlation to pathological findings. Methods Experimental study with immunohistochemistry analysis of Ki-67, calculating the percentage of the cell proliferation index in glottic squamous cell carcinomas. Results Sixteen cases were analyzed, with six well-differentiated and 10 poorly/moderately differentiated tumors. There was a correlation between cell proliferation index and degree of cell differentiation, with higher proliferation in poorly/moderately differentiated tumors. Conclusion The cell proliferation index, as measured by Ki-67, may be useful in the characterization of histological degree in glottic squamous cell tumors.

Abstract
Introduçáo A cirurgia endoscópica endonasal ganhou aceitação crescente por otorrinolaringologistas e neurocirurgiões. Em muitos centros, esta tecnica é agora rotineiramente utilizada para as mesmas indicações que a técnica microcirúrgica convencional. Objetivo Descrever resultados cirúrgicos relativos à remissão hormonal, ressecção do tumor e complicações de série consecutiva de pacientes com adenoma da hipófise submetidos à ressecção endoscópica. Método Estudo de série de pacientes consecutivos com adenomas da hipófise, submetidos à cirurgia endoscópica endonasal, avaliados quanto à taxa de tumor residual, remissão funcional, sintomas, complicações e o tamanho do tumor. Resultados De 47 pacientes consecutivos, 17 eram portadores de adenomas funcionantes, sete produtores de GH, cinco com doença de Cushing e cinco prolactinomas. Dos adenomas funcionantes, 12 foram macroadenomas, cinco microadenomas, e 30 macroadenomas não funcionantes. Dos adenomas funcionantes, 87% melhoraram. Em relação ao déficit visual, 85% melhoraram ao longo do tempo. A maioria dos pacientes que apresentou queixas de cefaléia melhorou (76%). Complicações cirúrgicas ocorreram em 10% dos pacientes, com duas lesões da carótida, duas fístulas liquóricas e uma fatalidade em um paciente com um histórico complicado. Conclusão A cirurgia hipofisária endoscópica endonasal é uma técnica viável, rendendo bons resultados cirúrgicos e funcionais e baixa morbidade. © 2014 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Abstract
6073 Background: Recently, we found 6.609 genetic single nucleotide polymorphisms (SNPs) with distinct frequencies between base of tongue squamous cell carcinoma (BTSCC) patients and controls. The study was performed using high-resolution DNA microarrays genotyping (Affymetrix). The SNPs identified never have been previously described with BTSCC risk. Some SNPs of interest were located in genes related to cell cycle (ERP29, LEF1, MCC and PTCH1) and DNA transcription (IKBKAP and ZNF415) and they were selected to validation process. Objective: Validate the SNPs ERP29 c.*293A>G (rs7114); LEF1 c.*1213A>G (rs2107028) and g.127267A>G (rs4245926); MCC c.*5077A>G (rs7033); PTCH1 g.27369025G>A (rs16909856) and g.27369324G>A (rs16909859); IKBKAP c.3214T>A (rs3204145) and ZNF415 c.*443A>G (rs3814) associated to BTSCC risk. Methods: Genomic DNA from 49 BTSCC patients and 49 controls was genotyping by TaqMan assays (Applied Biosystems). The differences between groups were analyzed by logistic regression model. Power analysis (PA) was used to verify the effect of sample size on the results obtained. Results: Eight SNPs identified by Affymetrix were validated by TaqMan assays. The frequencies of ERP29 c.*293AG+GG (30 vs 11%, P=0.03; PA=65%), LEF1 c.*1213AA+AG (95 vs 80%, P=0.02; PA=61%) and g.127267AA+AG (93 vs 78%, P=0.02; PA=56%), MCC c.*5077AA+AG (85 vs 64%, P=0.008; PA=67%), PTCH1 g.27369025GG+GA (90 vs 73%, P=0.005; PA=58%) and g.27369324GG+GA (90 vs 73%, P=0.008; PA=58%), IKBKAP c.3214TT+TA (90 vs 72%, P=0.01; PA=62%) and ZNF415 c.*443AA+AG (59 vs 41%, P=0.02; PA=43%) were more common in patients than in controls. Individuals with these genotypes were at 2.9(CI95%: 1.1-8.4), 3.9 (CI95%: 1.4-11.2), 4.0 (CI95%: 1.2-14.7), 3.5 (CI95%: 1.2-11.9), 5.0 (CI95%: 1.7-16.9), 4.5 (CI95%: 1.5-15.2), 4.1 (CI95%: 1.4-12.9), and 3.9 (CI95%: 1.2-13.7)-fold increased risks for BTSCC than others, respectively. Conclusions: Our data present for the first time evidence that inherited abnormalities in ERP29, MCC, LEF1, PTCH1, IKBKAP, and ZNF415 genes may be important determinants of BTSCC.

Abstract
The removal of level II, III, and IV metastases has gained importance in the treatment of squamous cell carcinomas (SCC) of the neck and larynx. This study assessed the possibility of removing level II and level III metastases only, given the low likelihood of occurrence of metastatic lymph nodes on level IV in SCCs of the larynx. Objective This study aimed to analyze the prevalence rates of metastatic lymph nodes on level IV in laryngeal SCC patients. Methods This prospective study enrolled consecutive patients with laryngeal SCC submitted to neck lymph node dissection. Neck levels were identified and marked for future histopathology testing. Results Six percent (3/54) of the necks had level IV metastatic lymph nodes. All cN0 necks (42) were free from level IV metastasis. Histopathology testing done in the cN (+) necks (12) revealed that 25% of the level IV specimens were positive for SCC. The difference between cN0 and cN (+) necks was statistically significant (p = 0.009). Level IV metastases never occurred in isolation, and were always associated with level II or level III involvement (p = 0.002). Conclusion The prevalence rate for lymph node metastasis in cN0 necks was 0%. Level IV metastatic lymph nodes were correlated to cN (+) necks. Level IV metastasis was associated with the presence of metastatic lymph nodes in levels II or III.

Abstract
The modified rhytidectomy incision is an alternative to the classic cervicomastoidfacial approach for parotid surgery, camouflaging the scar in barely visible areas, resulting in better cosmesis. However, there are very few studies comparing the incidence of complications and functional results of patients submitted to parotidectomy through these two different approaches. Objective Compare the incidence of complications and functional results of patients with benign parotid neoplasms submitted to surgery through the classical incision versus the modified rhytidectomy approach. Method Retrospective cohort study evaluating the demographics, surgical and post-operative characteristics of an equally distributed group of sixty patients submitted to parotidectomy via cervicomastoidfacial incision or modified rhytidectomy approach. Results There were no significant differences in complications rates and functional results between the groups, except for a lower incidence of early facial movement dysfunction for the modified rhytidectomy approach - which was 86% lower in this group of patients. Conclusion Modified rhytidectomy incision has shown comparable complication rates to those of the classic approach and a lower incidence of immediate facial movement impairment.

Abstract
Hypocalcemia is the most common complication after total thyroidectomy. Intact parathyroid hormone (i-PTH) testing is a proven effective method to detect patients at risk for postoperative symptomatic hypocalcemia. However, there is still uncertainty as to the timing of i-PTH testing in a clinical setting. Objective This study looked into the correlation between serum i-PTH levels measured at different times after total thyroidectomy and the risk of symptomatic hypocalcemia. Methods This retrospective case series studied a group of 110 consecutive for hypocalcemia and intact parathyroid hormone (PTHi) levels four and twelve hours following total thyroidectomy. Statistical analysis was used to evaluate the performance of isolated and serial i-PTH measurements to determine the likelihood of symptomatic hypocalcemia. Results I-PTH is highly sensitive (90.3%-96.8%) and specific (77.2%-87.3%) for symptomatic hypocalcemia. There was no significant difference in the sensitivity levels of the tests done four and twelve hours after surgery or in a serial fashion. However, the 12-hour i-PTH level was more specific (p < 0.0007). Conclusion Single i-PTH testing done 12 hours after total thyroidectomy may be used as a screening test to detect patients at risk for symptomatic hypocalcemia.
