RESUMO
It is well established that olfactory dysfunction has significant implications for safety, nutrition, and quality of life. The more reliable standardized tests of olfactory function, such as the University of Pennsylvania Smell Identification Test (UPSIT), assess odor identification ability. Unfortunately, cultural factors can influence such tests, as a number of odors are not universally recognized. In this study, a Portuguese language version of the UPSIT was administered to an age- and sex-stratified prospective sample of 1820 Brazilian subjects. Normative data were developed for a subset of 1578 subjects who reported having no difficulties smelling or tasting. Individuals with a history of head trauma or, in the case of those over the age of 64 years, Mini-Mental State Examination Scores <24, were excluded from analysis. As in other populations, the test scores were significantly influenced by age and sex. The median overall difference between the North American and Brazilian UPSIT scores was 2.2 points for men and 0.8 points for women, although subtle age-related differences were also apparent. This research represents that largest clinical study of olfaction ever performed in South America. Correction factors based upon age and sex are provided to allow for direct comparisons of Brazilian test scores to those based upon North American norms.

The lateral recess of the sphenoid sinus is one of the most common sites of meningocele and spontaneous cerebrospinal fluid (CSF) leak. Despite the availability of several techniques for closure of skull base defects occurring in this location, recurrence still poses a major challenge. This report reviews the experience of surgical repair of lateral sphenoid sinus recess CSF leak at a tertiary referral center and provides a brief discussion of this rare lesion. Nine surgeries were performed for six cases of spontaneous lateral sphenoid sinus recess CSF leak (two revisions and one repair of a new defect). Two patients presented with intracranial hypertension (ICH) and four with meningocele or meningoencephalocele. The transpterygoid approach was used in two procedures. A multilayer graft was used in seven cases and a nasoseptal flap in two. Three patients received lumbar or ventricular shunts, and one received acetazolamide for ICH management. Two minor complications were recorded, and the overall surgical success rate was 78 %. We conclude that nasoseptal flaps are a valid option for repair of recurrent CSF leaks, particularly in the lateral sphenoid sinus recess. Furthermore, identification and correction of ICH plays an essential role in the success of treatment in this patient population.

Introduction Primary ciliary dyskinesia (PCD) is a rare inherited disease associated with impairment of mucociliary transport and, consequently, with a high incidence of chronic rhinosinusitis. For patients with chronic rhinosinusitis who remain symptomatic despite medical treatment, endoscopic sinus surgery is a safe and effective therapeutic option. However, to date, no studies have been found evaluating the effect of surgery on the quality of life associated with the effect on olfaction and nasal endoscopy findings of patients with primary ciliary dyskinesia and chronic rhinosinusitis. Objective To describe the effect of endoscopic sinus surgery on the quality of life, on olfaction, and on nasal endoscopy findings of adults with PCD and chronic rhinosinusitis. Methods Four patients who underwent endoscopic sinus surgery were included. The Sinonasal Outcome Test-22 (SNOT-22) score, the Nasal Obstruction Symptom Evaluation (NOSE) questionnaire, and the Lund-Kennedy score were collected preoperatively and at 3 and 6 months postoperatively. The olfaction as assessed with the University of Pennsylvania Smell Identification Test (UPSIT), which was administered preoperatively and 3 months postoperatively. Results A total of 4 patients with a mean age of 39.3 years old (3 men and 1 woman) completed the study. All patients showed clinically significant improvement in the SNOT-22, NOSE, and Lund-Kennedy scores at 3 months postoperatively, and this improvement was sustained throughout the follow-up period. However, olfaction did not improve after surgery. Conclusion The endoscopic sinus surgery treatment of chronic rhinosinusitis in adults with PCD was associated with improvement in quality of life and endoscopic findings. However, no improvement in olfaction was demonstrated. Studies with a larger number of patients and control groups should help confirm these findings.
RESUMO
BACKGROUND: Previous studies demonstrated the difficulty of patients with Head and Neck Cancer (HNC) in sensing food taste, a function in which olfaction has a significant role. However, neither study employed psychophysical tests or control groups to establish the veracity of such complaints. AIMS/OBJECTIVES: In this study, we quantitatively tested the olfactory function of HNC individuals and compared their function to that of healthy controls. METHODS: Thirty-one HNC naïve treatment patients and thirty-one controls, matched for sex, age, schooling, and smoking, were tested with the University of Pennsylvania Smell Identification Test (UPSIT). RESULTS: The olfactory function was significantly worse among the patients diagnosed with head and neck cancer [UPSIT cancer = 22.9(CI 95%: 20.5-25.4) vs. UPSIT controls = 29.1(CI 95%: 26.9-31.3); p < .001]. Most patients with HNC had olfactory disorders (n = 29, 93.5%). The risk of olfactory loss was higher in the cancer group [OR: 10.5(CI 95%: 2.1-51.9; p = .001)]. CONCLUSION AND SIGNIFICANCE: Olfactory disorders can be detected in more than 90% of patients with head and neck cancer when evaluated using a well-validated olfactory test. Smell disorders may be a potential marker for early diagnosis of HNC.

OBJECTIVES: To examine the longitudinal prevalence and recovery of olfactory, gustatory, and oral chemesthetic deficits in a sizable cohort of SARS-CoV-2 infected persons using quantitative testing. To determine whether demographic and clinical factors, mainly the medications used after the COVID-19 diagnosis, influence the test measures. METHODS: Prospective cohort in a hospital with primary, secondary, tertiary, and quaternary care. Patients with confirmed COVID-19 were tested during the acute infection phase (within 15 days of initial symptom, n = 187) and one (n = 113) and 3 months later (n = 73). The University of Pennsylvania Smell Identification Test, the Global Gustatory Test, and a novel test for chemesthesis were administered at all visits. RESULTS: During the acute phase, 93% were anosmic or microsmic and 29.4% were hypogeusic. No one was ageusic. A deficit in oral chemesthesis was present in 13.4%. By 3 months, taste and chemesthesis had largely recovered, however, some degree of olfactory dysfunction remained in 54.8%. Remarkably, patients who had been treated with anticoagulants tended to have more olfactory improvement. Recovery was greater in men than in women, but was unrelated to disease severity, smoking behavior, or the use of various medications prior to, or during, COVID-19 infection. CONCLUSIONS: When using quantitative testing, olfactory disturbances were found in nearly all SARS-CoV-2 infected patients during the acute infection phase. Taste or chemesthetic deficits were low. Olfactory impairment persisted to some degree in over half of the patients at the 3-month follow-up evaluation, being more common in women and less common in those who had been treated earlier with anticoagulants. LEVEL OF EVIDENCE: 3.

INTRODUCTION: Olfactory epithelium biopsy has been useful for studying diverse otorhinolaryngological and neurological diseases, including the potential to better understand the pathophysiology behind COVID-19 olfactory manifestations. However, the safety and efficacy of the technique for obtaining human olfactory epithelium are still not fully established. OBJECTIVE: This study aimed to determine the safety and efficacy of harvesting olfactory epithelium cells, nerve bundles, and olfactory epithelium proper for morphological analysis from the superior nasal septum. METHODS: During nasal surgery, 22 individuals without olfactory complaints underwent olfactory epithelium biopsies from the superior nasal septum. The efficacy of obtaining olfactory epithelium, verification of intact olfactory epithelium and the presence of nerve bundles in biopsies were assessed using immunofluorescence. Safety for the olfactory function was tested psychophysically using both unilateral and bilateral tests before and 1 month after the operative procedure. RESULTS: Olfactory epithelium was found in 59.1% of the subjects. Of the samples, 50% were of the quality necessary for morphological characterization and 90.9% had nerve bundles. There was no difference in the psychophysical scores obtained in the bilateral olfactory test (University of Pennsylvania Smell Identification Test [UPSIT®]) between means before biopsy: 32.3 vs. postoperative: 32.5, pâ¯=â¯0.81. Also, no significant decrease occurred in unilateral testing (mean unilateral test scores 6 vs. 6.2, pâ¯=â¯0.46). None out of the 56 different odorant identification significantly diminished (pâ¯>â¯0.05). CONCLUSION: The technique depicted for olfactory epithelium biopsy is highly effective in obtaining neuronal olfactory tissue, but it has moderate efficacy in achieving samples useful for morphological analysis. Olfactory sensitivity remained intact.

INTRODUCTION: Although sinonasal inverted papillomas are benign lesions, they are locally aggressive and have a potential malignant transformation ranging from 5% to 15%, with a high recurrence rate. OBJECTIVE: The aim of this article is to describe the rate of recurrence and malignant transformation in patients with a diagnosis of inverted papilloma who underwent surgery in a tertiary hospital in São Paulo. METHODS: We performed a retrospective analysis of patients diagnosed with sinonasal papilloma who had undergone surgery in a tertiary hospital in São Paulo, between August 1998 and August 2017. A patient chart review was conducted to assess data of patients' demographics, tumors characteristics, follow-up appointments, recurrence and malignancy. Inverted papillomas were analyzed and classified under the Krouse staging system. RESULTS: A total of 69 surgeries were performed in patients with diagnosis of sinonasal papilloma. Inverted papilloma was the most prevalent subtype (49 cases â 80.33%), followed by exophytic papilloma (6 cases â 9.84%) and by oncocytic papilloma (6 cases - 9.84%). The recurrence rate was 34.09% for inverted papilloma (15/44) and the mean time of recurrence was 24.6 months. Malignant transformation occurred in 6 patients (13.64%). Three of these patients presented carcinoma in the first surgery and three patients developed carcinoma during the follow-up. CONCLUSION: The high recurrence rate and malignancy potential allow us to consider inverted papillomas as aggressive tumors. In a tertiary hospital in São Paulo the recurrence rate the mean time to recurrence is 24.6 months. The recurrence after 10 years implies was 34.09% and the need for long-term follow up. It is possible that the high recurrence rate and the high malignant transformation rate we found are due to the large number of tumors discovered at an advanced stage (most of them staged T3 and T4), secondary to poor access to health system, in developing countries.

OBJECTIVE: Our study aimed to measure the percentage of reported olfactory or taste losses and their severity, recovery time, and association with other features in a large cohort of patients with COVID-19. STUDY DESIGN: Prospective survey. SETTING: Quaternary medical center and online survey. METHODS: The perceived chemosensory capacities of 655 patients with confirmed COVID-19 were assessed with 11-point category rating scales (0, no function; 10, normal function). Patients were contacted in hospital, by phone calls, or by internet regarding their ability to smell or taste, and 143 were interviewed by phone 1 to 4 months later to assess the recovery of their chemosensory abilities. RESULTS: The prevalence of self-reported olfactory, general taste, and taste quality-specific disturbances (sweet, sour, bitter, and salty) in the patients with COVID-19 were 82.4% (95% CI, 79.5%-85.3%), 76.2% (95% CI, 72.9%-79.4%), and 52.2% (95% CI, 48.3%-56.1%), respectively. The majority reported anosmia (42.9%). The presence of chemosensory symptoms was not associated with COVID-19 severity. At a median time >2 months after the onset of symptoms, rates of total and partial olfaction recovery were 53.8% and 44.7%, while complete or partial return to previous taste function was 68.3% and 27.6%. Less than 5% of the patients reported no chemosensory function improvement at all. CONCLUSION: The prevalence of self-reported chemosensory dysfunction is high among patients with COVID-19. Almost all patients seem to recover a significant part of their smell and taste abilities in the first 4 months after the onset of symptoms.

Introduction Intra and postoperative bleeding are the most frequent and feared complications in adenotonsillectomy (AT). Tranexamic acid (TXA), which is known for its antifibrinolytic effects, has a proven benefit in reducing bleeding in hemorrhagic trauma and cardiac surgery; however, the effectiveness and timing of its application in AT have not yet been established. Objectives We aimed to evaluate the efficacy of TXA in controlling bleeding during and after AT and assess its possible adverse effects in children. Methods The present randomized, controlled, double-blind clinical trial included 63 children aged 2 to 12 years. They were randomly assigned to receive either intravenous TXA (10 mg/kg) or placebo 10 minutes before surgery. The volume of intraoperative bleeding, presence of postoperative bleeding, and adverse effects during and 8 hours after the surgery were assessed. Results No difference in bleeding volume was noted between the 2 groups (mean, 122.7 ml in the TXA group versus 115.5 ml in the placebo group, p = 0.36). No intraoperative or postoperative adverse effects were noted because of TXA use. Furthermore, no primary or secondary postoperative bleeding was observed in any of the participants. Conclusion In our pediatric sample, TXA (10 mg/kg) administration before AT was safely used, without any adverse effects. It did not reduce the bleeding volume in children during this type of surgery. Future studies should assess the use of higher doses of TXA and its administration at other time points before or during surgery.
RESUMO
Introduction Paranasal sinus mucocele is a benign, expansive lesion associated with paranasal sinus obstruction. It affects mostly adults, and is most common in the frontal and ethmoidal sinuses. Objective To evaluate outcomes in patients undergoing surgical treatment for paranasal sinus mucocele. Methods Retrospective review of medical records of patients treated for paranasal sinus mucocele at the ENT department of a tertiary care hospital between 2005 and 2016. Results Forty-six patients underwent surgical treatment of paranasal sinus mucocele. The mean age was 50.1 years, and 56.5% were male. The most prevalent symptom was pain, and the frontal sinus was most commonly affected. The vast majority of patients (89.1%) underwent endoscopic sinus marsupialization; 10.9% required combined open and endoscopic access. Seven recurrences occurred. Conclusion Sinus mucocele is an expansive disease that primarily affects the frontal sinus of adult patients. In most cases, endoscopic surgery is an effective treatment modality.
RESUMO
BACKGROUND: In this study, we employed a novel children's olfactory test in order to more accurately assess the relationship between nasopharyngeal obstruction and odor identification ability. We quantified the impact of adenoidectomy on olfactory function, established whether the influences of the operation were related to the preoperative amount of nasopharyngeal obstruction, and determined whether sex influenced the olfactory measures. METHODS: Fifty-three boys and 23 girls were administered a standardized children's olfactory test, the Pediatric Smell Wheel™, before and 45 days after adenoidectomy. They ranged in age from 5 to 12 years and exhibited varying degrees of adenotonsillar hypertrophy and histories of recurrent adenotonsillitis. Radiographs of the nasopharynx were used to grade the degree of nasopharyngeal obstruction. RESULTS: Significant postoperative improvement in smell function occurred more frequently in children with >50% preoperative obstruction of the nasopharynx. In this group, average function improved 50.8% after surgery (95% confidence interval [CI], 39.1% to 64%). Improvement on 9 of the 11 odors was present, with significant differences occurring for the odors of bubble gum, baby powder, mint, and cinnamon. No sex differences were evident. CONCLUSION: Olfactory dysfunction occurs primarily in children whose nasopharyngeal obstruction is >50%. Removal of the hypertrophied adenoids returned smell function back to normal in these cases. This study suggests that smell loss may be of value in decisions regarding whether or not to perform adenoidectomy in children with nasopharyngeal obstruction.

INTRODUCTION: Even the most modern radiation techniques still result in some degree of toxicity to adjacent normal tissues. Consequently, the radiotherapy treatment in head and neck neoplasms potentially leads to gustatory dysfunction even in cases when the treatment area is outside or adjacent to the oral cavity. In this study we quantitatively and qualitatively assessed gustatory function in patients with head and neck cancers who underwent radiotherapy inside and outside of the oral cavity. METHODS: Fifty-six patients with head and neck cancer responded to a specific questionnaire and had their gustatory function tested before, immediately after, and at 3 and 6 months following radiotherapy treatment. The irradiation field did not include the oral cavity in 29 patients and included it in 27 patients. RESULTS: All patients suffered a severe loss of taste immediately after radiotherapy. The identification of sweet and bitter tastes decreased in both groups, but the sour decrement was exclusive to those who had the oral cavity irradiated. Fourteen percent of patients complained of qualitative changes of taste, namely taste distortions. No impact of xerostomia on the taste measures was apparent. CONCLUSION: We found that patients with head and neck neoplasms submitted to radiotherapy have disturbed taste even when irradiation does not include the oral cavity. This deficit is worse immediately after the end of radiotherapy. Our findings do not support the hypothesis that decreased salivary flow is the major cause for radiation-induced changes in taste function.

OBJECTIVES: The clinical symptoms of Alzheimer's disease (AD) are preceded by a long asymptomatic period associated with "silent" deposition of aberrant paired helical filament (PHF)-tau and amyloid-beta proteins in brain tissue. Similar depositions have been reported within the olfactory epithelium (OE), a tissue that can be biopsied in vivo. The degree to which such biopsies are useful in identifying AD is controversial. This postmortem study had 3 main goals: first, to quantify the relative densities of AD-related proteins in 3 regions of the olfactory neuroepithelium, namely, the nasal septum, middle turbinate, and superior turbinate; second, to establish whether such densities are correlated among these epithelial regions as well as with semi-quantitative ratings of general brain cortex pathology; and third, to evaluate correlations between the protein densities and measures of antemortem cognitive function. METHODS: Postmortem blocks of olfactory mucosa were obtained from 12 AD cadavers and 24 controls and subjected to amyloid-beta and PHF-tau immunohistochemistry. RESULTS: We observed marked heterogeneity in the presence of the biomarkers of tau and amyloid-beta among the targeted olfactory epithelial regions. No significant difference was observed between the cadavers with AD and the controls regarding the concentration of these proteins in any of these epithelial regions. Only one correlation significant was evident, namely, that between the tau protein densities of the middle and the upper turbinate (r = .58, P = .002). CONCLUSION: AD-related biomarker heterogeneity, which has not been previously demonstrated, makes comparisons across studies difficult and throws into question the usefulness of OE amyloid-beta and PHF-tau biopsies in detecting AD.

Introduction The importance of our study lies in the fact that we have demonstrated the occurrence of mechanical dysfunction within polypoid tissues, which promotes the development of polyps in the nasal cavity. Objective To change the paradigm of nasal polyposis (NP). In this new conception, the chronic nasal inflammatory process that occurs in response to allergies, to pollution, to changes in the epithelial barrier, or to other factors is merely the trigger of the development of the disease in individuals with a genetic predisposition to an abnormal tissue remodeling process, which leads to a derangement of the mechanical properties of the nasal mucosa and, consequently, allows it to grow unchecked. Data Synthesis We propose a fundamentally new approach to intervening in the pathological process of NP, addressing biomechanical properties, fluid dynamics, and the concept of surface tension. Conclusion The incorporation of biomechanical knowledge into our understanding of NP provides a new perspective to help elucidate the physiology and the pathology of nasal polyps, and new avenues for the treatment and cure of NP.
RESUMO
Introduction The association between sinus and lung diseases is well known. However, there are scarce studies regarding the effects of sinus surgery on pulmonary function in lung transplant recipients. The present study describes our experience with sinus surgery in lung transplant recipients with chronic rhinosinusitis. Objectives To assess the impact of sinus surgery for chronic rhinosinusitis on pulmonary function and on inpatient hospitalization days due to lower respiratory tract infection in lung transplant recipients. Methods A retrospective study conducted between 2006 and 2012 on a sample of lung transplant recipients undergoing sinus surgery for chronic rhinosinusitis. Pulmonary function, measured by forced vital capacity (FVC) and forced expiratory volume in the first second (FEV1), as well as inpatient hospitalization days due to lower respiratory tract infection, were compared 6 months before and 6 months after sinus surgery. Results The FEV1 values increased significantly, and the inpatient hospitalization days due to bronchopneumonia decreased significantly 6 months after sinus surgery. The preoperative and postoperative median FEV1 values were 2.35 and 2.68 respectively ( p = 0.0056 ). The median number of inpatient hospitalization days due to bronchopneumonia 6 months before and 6 months after surgery were 32.82 and 5.41 respectively ( p = 0.0013 ). Conclusion In this sample of lung transplant recipients with chronic rhinosinusitis, sinus surgery led to an improvement in pulmonary function and a decrease in inpatient hospitalization days due to bronchopneumonia.

All patients showed clinically significant improvement in the SNOT-22, NOSE, and Lund-Kennedy scores at 3 months postoperatively, and this improvement was sustained throughout the follow-up period. However, olfaction did not improve after surgery. Conclusion The endoscopic sinus surgery treatment of chronic rhinosinusitis in adults with PCD was associated with improvement in quality of life and endoscopic findings. However, no improvement in olfaction was demonstrated. Studies with a larger number of patients and control groups should help confirm these findings.
RESUMO
INTRODUCTION: Functional endonasal endoscopic surgery is a frequent surgical procedure among otorhinolaryngologists. In 2014, the European Society of Rhinology published the "European Position Paper on the Anatomical Terminology of the Internal Nose and Paranasal Sinuses", aiming to unify the terms in the English language. We do not yet have a unified terminology in the Portuguese language. OBJECTIVE: Transcultural adaptation of the anatomical terms of the nose and paranasal cavities of the "European Anatomical Terminology of the Internal Nose and Paranasal Sinuses" to Portuguese. METHODS: A group of rhinologists from diverse parts of Brazil, all experienced in endoscopic endonasal surgery, was invited to participate in the creation of this position paper on the anatomical terms of the nose and paranasal sinuses in the Portuguese language according to the methodology adapted from that previously described by Rudmik and Smith. RESULTS: The results of this document were generated based on the agreement of the majority of the participants according to the most popular suggestions among the rhinologists. A cross-cultural adaptation of the sinonasal anatomical terminology was consolidated. We suggest the terms "inferior turbinate", "nasal septum", "(bone/cartilaginous) part of the nasal septum", "(middle/inferior) nasal meatus", "frontal sinus drainage pathway", "frontal recess" and "uncinate process" be standardized. CONCLUSION: We have consolidated a Portuguese version of the European Anatomical Terminology of the Internal Nose and Paranasal Sinuses, which will help in the publication of technical announcements, scientific publications and the teaching of the internal anatomical terms of the nose and paranasal sinuses in Brazil.

Objective This study aimed to determine the safety and efficacy of harvesting olfactory epithelium cells, nerve bundles, and olfactory epithelium proper for morphological analysis from the superior nasal septum. Methods During nasal surgery, 22 individuals without olfactory complaints underwent olfactory epithelium biopsies from the superior nasal septum. The efficacy of obtaining olfactory epithelium, verification of intact olfactory epithelium and the presence of nerve bundles in biopsies were assessed using immunofluorescence. Safety for the olfactory function was tested psychophysically using both unilateral and bilateral tests before and 1 month after the operative procedure. Results Olfactory epithelium was found in 59.1% of the subjects. Of the samples, 50% were of the quality necessary for morphological characterization and 90.9% had nerve bundles. There was no difference in the psychophysical scores obtained in the bilateral olfactory test (University of Pennsylvania Smell Identification Test [UPSIT®]) between means before biopsy: 32.3 vs. postoperative: 32.5, p= 0.81. Also, no significant decrease occurred in unilateral testing (mean unilateral test scores 6 vs. 6.2, p= 0.46). None out of the 56 different odorant identification significantly diminished (p> 0.05). Conclusion The technique depicted for olfactory epithelium biopsy is highly effective in obtaining neuronal olfactory tissue, but it has moderate efficacy in achieving samples useful for morphological analysis. Olfactory sensitivity remained intact.
Resumo Introdução A biópsia do epitélio olfatório tem sido útil para estudar diversas doenças otorrinolaringológicas e neurológicas, incluindo seu potencial para melhor compreender a fisiopatologia por trás das manifestações olfatórias na COVID‐19. No entanto, a segurança e eficácia da técnica de obtenção de epitélio olfatório humano ainda não estão totalmente estabelecidas. Objetivos Este estudo teve como objetivo determinar a segurança e eficácia da coleta de células do epitélio olfatório, feixes nervosos e epitélio olfatório adequados para análise morfológica, no septo nasal superior. Método Durante a cirurgia nasal, 22 indivíduos sem queixas olfatórias foram submetidos a biópsias de epitélio olfatório do septo nasal superior. A eficácia da obtenção de epitélio olfatório, a verificação de epitélio olfatório íntegro e a presença de feixes nervosos nas biópsias foram avaliadas por imunofluorescência. A segurança da função olfatória foi testada psicofisicamente usando testes unilaterais e bilaterais antes e um mês após o procedimento cirúrgico. Resultados Epitélio olfatório foi encontrado em 59,1% dos sujeitos. Das amostras, 50% apresentaram a qualidade necessária para a caracterização morfológica e 90,9% continham feixes nervosos. Não houve diferença nos escores psicofísicos obtidos no teste olfatório bilateral (University of Pennsylvania Smell Identification Test [UPSIT®]) entre as médias antes da biópsia: 32,3 vs. pós‐operatório: 32,5, p = 0,81. Além disso, nenhuma diminuição significante ocorreu no teste unilateral (escore médio do teste unilateral 6 vs. 6,2, p = 0,46). Não houve redução significante na identificação de nenhum dos 56 odorantes diferentes (p > 0,05). Conclusão A técnica descrita para biópsia de epitélio olfatório é altamente eficaz na obtenção de tecido olfatório neuronal, mas tem eficácia moderada na obtenção de amostras adequadas para análise morfológica. A capacidade olfativa permaneceu intacta.
