The effect of early radiofrequency turbinate reduction, intranasal steroid, and antihistamine H-1 on persistent allergic rhinitis: a randomized clinical trial

Abstract Objective: We aimed to evaluate the effect of radiofrequency turbinate reduction as an initial treatment on clinical improvement, inflammatory mediators, and remodeling process. Methods: Between July 2018- February 2020, 32 patients with moderate-severe persistent AR were randomly divided into 2 groups. Intervention group received radiofrequency turbinate reduction followed by intranasal steroid and Antihistamine H-1 (AH-1), control group received intranasal steroid and AH-1. Both groups were evaluated for clinical improvement (using visual analogue scale based on total nasal symptoms score, peak nasal inspiratory flow, and turbinate size using imageJ) after 4 and 8 weeks of treatment. Inflammatory mediators (ELISA from nasal secretions was performed to measure ECP, IL-5, and HSP-70) and remodeling markers (nasal biopsy followed by immunohistochemistry examination was performed to evaluate MMP-9, TIMP-1, and PAI-1) were evaluated in week 4. Results: Three patients dropped out of the study, resulting in 16 patients in intervention group and 13 patients in control group. At week 4, clinical response improved significantly in the intervention group compared to control group (Chi-Square test, p<0.05). Compared to control, intervention group experienced a reduction of IL-5 and no significant change in ECP level (Mann Whitney test, p>0.05). Reduction in the ratio of MMP-9/TIMP-1 were significantly higher in intervention group (unpaired t-test, p< 0,05). Meanwhile, increase in HSP-70 in the intervention group was slightly lower than in control group, but the difference with control group was not significant (Mann Whitney test, p>0.05). Conclusion: Early radiofrequency turbinate reduction followed by pharmacotherapy given to persistent moderate-severe AR patients give more improvement only in early clinical symptoms and reduce MMP-9/TIMP-1 ratio, thus it might be suggested as one of the adjuvant therapies for the management of moderate-severe persistent AR. However, further investigation with a larger sample size and longer follow-up period is needed. Level of evidence: 1B.

Cirugía de cornetes inferiores en población pediátrica: ¿Cómo, cuándo y por qué? / Inferior turbinate surgery in pediatric population: How, when and why?

La hipertrofia de cornetes inferiores representa una de las principales causas de obstrucción nasal en pacientes pediátricos. En estudios recientes se ha observado un aumento significativo de esta patología en niños que no responden a terapia médica. La evidencia disponible recomienda la cirugía como tratamiento de elección en la obstrucción nasal refractaria en niños con cornetes hipertróficos. Sin embargo, hasta la fecha no existen criterios formales de derivación a cirugía en la población pediátrica y los estudios en infantes son limitados. Al mismo tiempo, la falta de consenso no ha permitido recomendar una técnica quirúrgica en estos pacientes por sobre otras. Por lo tanto, se hace necesario profundizar las diferentes alternativas disponibles, considerando y optando por aquellas que presenten mayores beneficios y menor riesgo de complicaciones. En la presente revisión se estudió la evidencia disponible hasta el momento sobre este tema en la población pediátrica y además se realizó un análisis de la efectividad y complicaciones de las diferentes técnicas disponibles.

Inferior turbinate hypertrophy represents one of the leading causes of nasal obstruction in pediatric patients. Recent studies have observed a significant increase in turbinate hypertrophy in children that does not respond to medical treatment. The latest evidence recommends inferior turbinoplasty for treating nasal obstruction in children with hypertrophic turbinates. However, until today there are no formal criteria for referral to surgery in the pediatric population, and studies in children are limited. At the same time, the absence of consensus has not allowed the recommendation of one surgical technique over others in these patients. This is why it is necessary to deepen the available alternatives and choose those with more significant benefits and a lower risk of complications. In this review, we study available evidence about this topic in the pediatric population and analyze the effectiveness and complications of different known techniques.

Hipertrofia de cornetes inferiores: revisión sobre técnicas quirúrgicas actuales / Inferior turbinate hypertrophy: review of current surgical techniques

La obstrucción nasal es un motivo de consulta habitual en otorrinolaringología, siendo una de las causas más frecuentes la hipertrofia de cornete inferior, la que se puede manejar con cirugía cuando falla el tratamiento médico. En las últimas décadas se han desarrollado múltiples técnicas quirúrgicas y tecnología asociada, sin embargo, no hay un consenso establecido sobre cuál es la mejor opción para el manejo de esta patología. Se realizó revisión bibliográfica, se enuncian los métodos quirúrgicos disponibles, teniendo en cuenta beneficios, complicaciones probables y resultados de cada uno. La cirugía de cornete inferior tiene resultados favorables en pacientes con cornetes hipertróficos que no responden a manejo médico. Hasta la fecha la turbinoplastía con microdebridador ha mostrado superioridad en cuanto a resultados a largo plazo y menor tasa de complicaciones. La evidencia disponible hasta la fecha carece de homogeneidad en cuanto a métodos de selección de pacientes, medición de resultados y tiempo de seguimiento, por lo que se necesitan a futuro estudios prospectivos controlados para reevaluar los métodos descritos.

Nasal obstruction is a common complaint, one of the most frequent causes being inferior turbinate hypertrophy, which can be managed with surgery when medical treatment fails. In the last decades, multiple surgical techniques and associated technology have been developed, however, there is no established consensus on what is the best option for the management of this pathology. Literature review, the available surgical methods are stated, taking into account benefits, probable complications and results of each technique. The surgery of inferior turbinate has favorable results in patients with hypertrophic turbinates that do not respond to medical management. To date, microdebrider turbinoplasty has shown superiority in terms of long-term results and lower complication rates. The evidence available to date lacks homogeneity in terms of patient selection methods, measurement of results and follow-up time, so prospective controlled studies are needed in the future to reassess the described methods.

Effects of turbinoplasty versus outfracture and bipolar cautery on the compensatory inferior turbinate hypertrophy in septoplasty patients / Efeitos da turbinoplastia versus fratura lateral e cauterização bipolar no volume da concha inferior hipertrófica compensatória em pacientes submetidos a septoplastia

Abstract Introduction: The most common cause of septoplasty failure is inferior turbinate hypertrophy that is not treated properly. Several techniques have been described to date: total or partial turbinectomy, submucosal resection (surgical or with a microdebrider), with turbinate outfracture being some of those. Objective: In this study, we compared the pre- and postoperative lower turbinate volumes using computed tomography in patients who had undergone septoplasty and compensatory lower turbinate turbinoplasty with those treated with outfracture and bipolar cauterization. Methods: This retrospective study enrolled 66 patients (37 men, 29 women) who were admitted to our otorhinolaryngology clinic between 2010 and 2017 because of nasal obstruction and who were operated on for nasal septum deviation. The patients who underwent turbinoplasty due to compensatory lower turbinate hypertrophy were the turbinoplasty group; Outfracture and bipolar cauterization were separated as the out fracture group. Compensatory lower turbinate volumes of all patients participating in the study (mean age 34.0 ± 12.4 years, range 17-61 years) were assessed by preoperative and postoperative 2 month coronal and axial plane paranasal computed tomography. Results: The transverse and longitudinal dimensions of the postoperative turbinoplasty group were significantly lower than those of the out-fracture group (p = 0.004). In both groups the lower turbinate volumes were significantly decreased (p = 0.002, p < 0.001 in order). The postoperative volume of the turbinate on the deviated side of the patients was significantly increased: tubinoplasty group (p = 0.033). Conclusion: Both turbinoplasty and outfracture are effective volume-reduction techniques. However, the turbinoplasty method results in more reduction of the lower turbinate volume than outfracture and bipolar cauterization.

Resumo Introdução: A causa mais comum de falha da septoplastia é a hipertrofia das conchas inferiores não tratada adequadamente. Diversas técnicas foram descritas até o momento: turbinectomia total ou parcial, ressecção da submucosa (cirúrgica ou com microdebridador) e a fratura lateral. Objetivo: Neste estudo, comparamos os volumes pré e pós-operatório da concha inferior com hipertrofia compensatória com o uso de tomografia computadorizada entre pacientes submetidos a septoplastia e turbinoplastia ou fratura lateral com cauterização bipolar. Método: Este estudo retrospectivo incluiu 66 pacientes (37 homens e 29 mulheres) internados em nosso serviço de otorrinolaringologia entre 2010 e 2017 por obstrução nasal e submetidos à cirurgia por desvio de septo nasal. Os pacientes submetidos à turbinoplastia devido à hiperplasia compensatória da concha inferior formaram o grupo turbinoplastia; aqueles submetidos à fratura lateral e cauterização bipolar foram separados, formaram o grupo fratura lateral. Os volumes compensatórios da concha inferior de todos os pacientes que participaram do estudo (idade média de 34,0 ± 12,4 anos, faixa de 17 a 61 anos) foram avaliados por tomografia computadorizada dos seios paranasais nos planos axial e coronal no pré-operatório e aos dois meses do pós-operatório. Resultados: As dimensões transversais e longitudinais do grupo turbinoplastia no pós-operatório foram significantemente menores do que as do grupo de fratura lateral (p = 0,004). Em ambos os grupos, os volumes da concha inferior diminuíram significantemente (p = 0,002, p < 0,001, respectivamente). O volume pós-operatório da concha do lado do desvio aumentou significantemente no grupo turbinoplastia (p = 0,033). Conclusão: Tanto a turbinoplastia como a fratura lateral são técnicas efetivas de redução de volume. No entanto, a turbinoplastia causa maior redução do volume da concha inferior do que a fratura lateral com cauterização bipolar.

Does the reduction of inferior turbinate affect lower airway functions? / A redução da concha nasal inferior afeta as funções das vias aéreas inferiores?

Abstract Introduction: Although the nose and lungs are separate organs, numerous studies have reported that the entire respiratory system can be considered as a single anatomical and functional unit. The upper and lower airways affect each other either directly or through reflex mechanisms. Objective: In this study, we aimed to evaluate the effects of the radiofrequency ablation of persistent inferior turbinate hypertrophy on nasal and pulmonary function. Methods: Twenty-seven patients with bilateral persistent inferior turbinate hypertrophy without septal deviation were included in this study. All of the patients were evaluated using anterior rhinoscopy, nasal endoscopy, acoustic rhinometry, a visual analogue scale, and flow-sensitive spirometry on the day before and 4 months after the radiofrequency ablation procedure. Results: The post-ablation measurements revealed that the inferior turbinate ablation caused an increase in the mean cross-sectional area and volume of the nose, as well as in the forced expiratory volume in 1 s, forced vital capacity, and peak expiratory flow of the patients. These differences between the pre- and post-ablation results were statistically significant. The post-ablation visual analogue scale scores were lower when compared with the pre-ablation scores, and this difference was also statistically significant. Conclusion: This study demonstrated that the widening of the nasal passage after the reduction of the inferior turbinate size had a favorable effect on the pulmonary function tests.

Resumo Introdução: Embora o nariz e os pulmões sejam órgãos separados, numerosos estudos relataram que todo o sistema respiratório pode ser considerado como uma única unidade anatômica e funcional. As vias aéreas superiores e inferiores afetam uma à outra diretamente ou através de mecanismos reflexos. Objetivo: Avaliar os efeitos da ablação por radiofrequência em conchas nasais inferiores com hipertrofia persistente sobre a função nasal e pulmonar. Método: Foram incluídos neste estudo 27 pacientes com hipertrofia persistente bilateral de conchas inferiores sem desvio septal. Todos os pacientes foram avaliados com rinoscopia anterior, endoscopia nasal, rinometria acústica, escala visual analógica e espirometria sensível ao fluxo no dia anterior e quatro meses após o procedimento de ablação por radiofrequência. Resultados: As medidas pós-ablação demonstraram que a ablação das conchas nasais inferiores resultou em um aumento da área transversal média e do volume do nariz, bem como do volume expiratório forçado em um segundo, da capacidade vital forçada e do fluxo expiratório máximo dos pacientes. Essas diferenças entre os resultados pré e pós-ablação foram estatisticamente significantes. Os escores da escala visual analógica pós-ablação foram menores quando comparados com os escores pré-ablação e essa diferença também foi estatisticamente significante. Conclusão: O alargamento da passagem nasal após a redução do tamanho das conchas nasais inferiores teve efeito favorável nos testes de função pulmonar.

Anatomical Variations of the Middle Turbinate Concha Bullosa and its Relationship with Chronic Sinusitis: A Prospective Radiologic Study

Abstract Introduction A pneumatized turbinate, also called concha bullosa, is a normal anatomical variant of the paranasal sinus region. Depending on the site of pneumatization, the concha is classified into extensive, bulbous or lamellar type. The middle turbinate concha bullosa has been implicated as a possible etiological factor in chronic sinusitis. Objectives The aim of this study was to investigate the anatomical variations of the concha bullosa, based on paranasal sinus imaging, and its possible association with sinusitis. Methods This prospective descriptive study was performed at the Department of ENT and Head Neck Surgery over a period of one year, from 2016 to 2017. We studied the computed tomography scans of the nose and paranasal sinuses- in axial, coronal and sagittal planes-of patients who had symptoms of nasal obstruction, or headache and features of chronic sinusitis. Results Out of the 202 scans studied, the prevalence of concha bullosa was 31.7%. The concha was bilateral in 35 (54.7%) patients and unilateral in 29 (45.3%) patients. Out of 99 conchae, 54 were on the right side and 45 were on left side. Ipsilateral sinusitiswas found in 40.4% of the sides in the scans of subjectswith concha. There was no statistically significant association between any type of middle turbinate concha with sinusitis, but sinusitis was more predominant with the extensive type of concha (p > 0.05). Conclusion Multiple air cells, mucocele, pyocele and inflammatory mucosal thickenings in the concha are relatively rare. Detailed knowledge of anatomic variations of the concha bullosa is imperative for the radiologists and the operating surgeons.

An often neglected area in crooked nose: middle turbinate pneumatization / Uma área frequentemente negligenciada no nariz torto: pneumatização da concha média

Abstract Introduction: Crooked or deviated nose is a deviation of the nose from the straight vertical position of the face. Extensive pneumatization of the middle turbinate, also called concha bullosa or bullous middle turbinate (BMT) is known to be one of the possible etiologic factors in nasal obstruction, recurrent sinusitis, and headache. There is no study concerning a link between BMT and crooked nose. Objective: To investigate the association between crooked nose and the presence of a BMT. Methods: A total of 199 patients who underwent open septorhinoplasty were retrospectively analyzed. Preoperative paranasal Computerized Tomography (CT) findings, preoperative photodocumentation, and anterior rhinoscopic examination findings were documented. Of the 199 patients, 169 were found to meet the criteria and were included in the study. CT scans were examined to note the presence of BMT, inferior turbinate hypertrophy, and septum deviation (SD). SDs and crooked noses were classified. Results: Ninety-four of 169 patients (56%) presented a crooked nose deformity and seventy-five of 169 patients (44%) presented a straight nose. While 49 (52%) crooked nose patients had a bulbous and extensive BMT, 20 patients with straight nose (26.6%) had a BMT. A statistically significant relationship was found between the presence of crooked nose and BMT, regardless of the side of the disease (p = 0.011). Conclusion: This study revealed a link between crooked nose and BMT.

Resumo Introdução: O nariz torto ou o nariz com desvio é um nariz com um desvio da posição vertical reta da face. A pneumatização extensa da concha média, também chamada de concha bolhosa ou concha média bolhosa (CMB), é conhecida por ser um dos possíveis fatores etiológicos da obstrução nasal, sinusite recorrente e cefaleia. Não há estudo relativo a uma associação entre CMB e nariz torto. Objetivo: Investigar a associação entre o nariz torto e a presença de CMB. Método: Foram analisados retrospectivamente 199 pacientes que se submeteram a septorrinoplastia aberta. Achados pré-operatórios paranasais à tomografia computadorizada (TC), fotodocumentação pré-operatória e exame rinoscópico anterior foram registrados. Dos 199 pacientes, observou-se que 169 atendiam aos critérios e foram incluídos no estudo. As TC foram examinadas para observar a presença de CMB, hipertrofia de conchas inferiores e desvio de septo (DS). Os DS e narizes tortos foram então classificados. Resultados: Dos 169 pacientes, 94 (56%) apresentavam uma deformidade de nariz e 75 (44%) apresentavam nariz reto. Enquanto 49 (52%) pacientes com nariz torto tinham CMB extensa, 20 pacientes com nariz reto (26,6%) tinham CMB. Uma relação estatisticamente significativa foi encontrada entre a presença de nariz torto e CMB, independentemente do lado da doença (p = 0,011). Conclusão: Este estudo revelou uma relação entre o nariz torto e CMB.

Comparison of turbinoplasty surgery efficacy in patients with and without allergic rhinitis / Comparação da eficácia da turbinoplastia em pacientes com e sem rinite alérgica

ABSTRACT INTRODUCTION: Turbinoplasty is a procedure that aims to reduce the size of the inferior turbinate through exuberant bone removal with high mucosal preservation. The procedure is recommended for patients with or without allergic rhinitis and those showing irreversible hypertrophy of inferior turbinates. OBJECTIVE: To evaluate the efficacy of inferior turbinoplasty for obstructive and non-obstructive symptoms in patients with or without allergic rhinitis. METHODS: Prospective study with 57 patients who underwent inferior turbinoplasty. They were evaluated for nasal obstruction, snoring, facial pressure, smell alterations, sneezing, nasal itching and runny nose symptoms, surgery time, and intraoperative bleeding. The last evaluation took place three months after surgery. RESULTS: Thirty-nine patients with allergic rhinitis and 18 without were assessed. Ninety days after surgery, 94.7% of patients showed degrees IV and V of breathing improvement; 89.5% showed moderate or complete improvement in snoring; all patients showed smell improvement (only one showed moderate improvement; all the others had full improvement); 95.5% experienced complete facial pressure improvement; and 89.7% showed moderate to complete improvement in nasal itching and runny nose symptoms, as well as in sneezing. CONCLUSION: The efficacy of inferior turbinoplasty was confirmed not only for obstructive symptoms, but also for non-obstructive symptoms in patients with and without allergic rhinitis.

RESUMO INTRODUÇÃO: A turbinoplastia é procedimento que visa a redução da concha inferior, à custa da remoção óssea exuberante e maior preservação da mucosa. É indicada para pacientes com e sem rinite alérgica, com hipertrofia irreversível das conchas inferiores. OBJETIVO: Avaliar a eficácia da cirurgia de turbinoplastia inferior nos sintomas obstrutivos e não obstrutivos em pacientes com e sem rinite alérgica. MÉTODO: Estudo prospectivo com 57 pacientes submetidos a turbinoplastia inferior. Foram avaliados quanto à obstrução nasal, roncos, pressão facial, alterações no olfato, espirros, prurido nasal e coriza, tempo de cirurgia e sangramento intraoperatório. A última avaliação foi com 3 meses de operação. RESULTADOS: 39 pacientes com rinite alérgica e 18 sem. Com 90 dias de operação, 94,7% dos pacientes apresentaram graus IV e V de melhora na respiração; 89,5% apresentaram melhora moderada ou total dos roncos; todos os pacientes tiveram melhora no olfato (apenas 1 moderada, os demais melhora total); 95,5% obtiveram melhora total da pressão facial e 89,7% obtiveram melhora moderada ou total em prurido nasal, espirros e coriza. CONCLUSÃO: Comprovou-se a eficácia da cirurgia de turbinoplastia inferior não só nos sintomas obstrutivos, mas também nos sintomas não obstrutivos tanto em pacientes com ou sem rinite alérgica.

Cefalea rinogénica ¿mito o realidad?: displasia fibrosa de cornete medio como causa de algia facial / Rhinogenic headache ¿myth or reality?: middle turbinate fibrous displasia, as a cause of facial pain

La cefalea es uno de los motivos de consulta más frecuentes en medicina y se clasifica como primaria en cefaleas tensionales o migrañas y secundaria a tumores, infecciones u otras causas. Dentro del grupo de cefaleas o algias faciales secundarias se plantea la existencia del cuadro clínico de cefalea rinogénica generada por puntos de contacto de la mucosa de la cavidad nasal. En este artículo se presenta un caso de una paciente que posterior al fracaso del tratamiento farmacológico para migraña, consultó por algia facial persistente. Al realizar un examen clínico y con tomografía computarizada de las cavidades perinasales, se diagnosticó una cefalea rinogénica por contacto de mucosa secundaria a una displasia fibrosa del cornete medio. La resección quirúrgica del punto de contacto a través de una turbinectomía media realizada por cirugía endoscópica nasal abolió totalmente el dolor facial. Este caso recalca la utilidad y necesidad del estudio de las cavidades perinasales en aquellos pacientes que presentan cefalea o algia facial.

Headache is one of the most frequent symptoms in medicine that can be classified as primary, like tensional headache and migraine or secondary as in tumors, infections, or other causes. Rhinogenic headache is proposed as a clinical entity secondary to mucosal contact points within the nasal cavity. In this article we present a case of a patient that after a pharmacological treatment failure for migraine, consulted for sustained facial pain. After clinical examination and a paranasal sinus computed tomography, a rhinogenic headache secondary to middle turbinate fibrous dysplasia was diagnosed. Endoscopic surgical extirpation of contact mucosal points by a medial turbinectomy produced complete abolition of facial pain. This case illustrates the need and utility of studying paranasal sinus in those patients with headache or facial pain.

Angiofibroma of middle turbinate

We report a rare case of angiofibroma of middle turbinate. A man of 17 years presented to out patient department [OPD] of ENT, Head and Neck Surgery Postgraduate Medical Institute, Lady Reading Hospital, Peshawar, Pakistan with presenting complaint of progressive obstruction of right side of nasal cavity for last 3 months. On ENT examination there was a reddish fleshy mass in the right nasal cavity. It was firm on probing, arising from the middle turbinate of lateral wall of nasal cavity and was sensitive on touching. On CT scan the mass was limited to lateral wall of right side of nasal cavity which was iso-dense with no bony erosion. The mass was removed in toto intranasally and specimen was sent for histopathology study. The histopathology report was angiofibroma. The patient is followed regularly and he is disease free so far

Comparative study of efficacy of mucosal electrocautry versus submucosal diathermy for the treatment of inferior turbinate hypertrophy of nose

To compare the efficacy of submucosal electrocautry versus submucosal diathermy for the surgical treatment of inferior turbinate hypertrophy of nose and to analyze the outcome of both treatment options. Retrospective study was done in 100 cases at the department of otorhinolaryngology, head and neck surgery department JPMC and PMCH Nawabshah, form January 2007 to July 2008. The patients suffering from inferior turbinate hypertrophy were included in this study having ages between 20 to 35 years. Demographic data were obtained from the patient files at the Hospital and were complied for result. Among one hundred patients which were evaluated and surgically treated, 30 cases were of allergic rhinitis, 28 cases of vasomotor rhinitis, 22 cases were of chronic hypertrophic rhinitis and rest of 20 cases had mild septal deviation. The results were evaluated for the patients, pre-, post-operative symptoms and clinical findings. Submucosal diathermy was found more successful in relieving the patients' symptoms and decreasing the size of the inferior turbinates as compared to mucosal electrocautry

Pathological changes in turkeys experimentally infected with different doses of A/ostrich/Italy/984/2000 H7N1 avian influenza virus

Following experimental inoculation of 3-week-old turkeys with different titres [10[6], 10[4], 10[3], 10[2] and 10[1] egg infectious dose [EID50]] of A/ostrich/Italy/984/2000 H7NI highly pathogenic avian influenza virus [HPAIV], the selected tissues and organs were examined for pathological changes. Tissue samples from different organs that obtained from dead and sacrificed birds were fixed in 10% neutral buffer formaldehyde. Mortality of turkeys which inoculated with different doses of EID50 at different times post inoculation [PI] is as follows: 1] at 48 h PI [HPI]: one, two and four turkeys inoculated with 10[3], 10[4] and 10[6] EID50, respectively 2] at 72 HPI: two, two and one turkeys inoculated with 10[2], 10[3] and 10[6] EID50, respectively 3] at 96 HPI: one and two turkeys inoculated with 10[2] and 10[4] EID50, respectively and 4] at 120 HPI: just one turkey inoculated with 10[4] EID50. Birds inoculated with 10[1] EID50 did not show any mortality. Seven days PI [DPI] the remaining birds were sacrificed. Postmortem examination of birds that died 48 HPI showed very severe hyperaemia and haemorrhage of the lung, slight swelling of kidneys and splenomegaly. Moderate to slight hyperaemia of the lung was observed in the birds sacrificed on day 7. Histopathology showed very severe haemorrhage and vasculitis in the lung, multifocal areas of degeneration and necrosis in the pancreas of birds inoculated with 10[6] EID50. Hyperaemia, haemorrhage, degeneration and vasculitis were also observed in the lung of birds from the other groups; however the severity of lesions correlated positively with the viral dose. The spleen, caecal tonsils and thymus showed extensive necrosis and lymphoid depletion, even in birds inoculated with 10[2] and 10[1] EID50 that were sacrificed 7 DPI, and some repopulation of the spleen was observed 7 DPI. Other organs including the kidneys and adrenal gland showed moderate to slight hyperaemia and necrosis. In conclusion, the lung vascular damage, lymphoid tissue destruction and necrosis were notable even with low viral doses

Comparison of sub mucosal diathermy and partial resection of Inferior turbinate in the treatment of symptomatic nasal valve blockage.

OBJECTIVES: to evaluate the efficacy of sub mucosal diathermy (SMD) and partial resection of inferior turbinate (PRIT) in the treatment of symptomatic enlarged inferior turbinates. STUDY DESIGN: prospective. METHODS: Forty patients of age group 18 -56 yrs with symptomatic enlarged inferior turbinates had given choices for SMD and PRIT. All the patients had history of failed medical treatment. RESULTS: Each twenty patients underwent SMD (group I), PRIT (group II), five pt of gr. I had to have anterior nasal packing after surgery for bleeding. Three pt complained of excessive rhinorrhoea for first 2 weeks while 3 pt of Group 1 complained of nasal blockage for 1 week even after intervention. In group 2, 5 pt had to have re-anterior nasal packing after pack removal. Both groups followed up for 6 months. Nine patients were lost in follow up, so excluded from the study. Following 6 months of follow up, 6 patient of gr. I had recurrence with nasal blockage and in gr. II none had recurrence. CONCLUSION: PRIT is better than SMD in long course; nevertheless it should be reserved for failed SMD, not as a primary option.

Tratamiento quirúrgico de la hipertrofia de los cornetes inferiores con plasma argón / Surgical treatment of the hypertrophy of the inferior turbinal bones with argon plasma

En nuestras consultas atendemos con frecuencia la obstrucción nasal crónica y la causa más frecuente es la hipertrofia de los cornetes inferiores. Cuando estos pacientes no tienen una respuesta positiva al tratamiento médico y luego de analizar los resultados del estudio de la enfermedad alérgica de estos, es que decidimos realizar la reducción quirúrgica del tamaño de los cornetes inferiores. Entre las técnicas utilizadas para este propósito se encuentra la coagulación con plasma argón, un procedimiento que utiliza corriente eléctrica de alta frecuencia y una fuente de plasma argón. La reducción efectiva de los cornetes, la posibilidad de alcanzarlo en toda la longitud de estos, la penetración limitada, el poco tiempo quirúrgico y la ausencia de complicaciones hemorrágicas entre otras ventajas, hacen de esta técnica algo excepcional. Fueron atendidos 40 pacientes diagnosticados de rinitis crónica hipertrófica, quienes fueron revisados a los 3 meses, 12 meses y 24 meses después del tratamiento. A los 24 meses, 38 pacientes (95 por ciento) refirieron una mejoría significativa de los síntomas. Se revisan y discuten las indicaciones, ventajas, complicaciones y resultados a largo plazo del uso de la coagulación con plasma argón en rinocirugía(AU)

In our consultations we frequently assist the obstruction nasal chronicle and the most frequent cause is the hipertrofia of the inferior cornetes. When these patients don't have a positive answer to the medical treatment and after analyzing the results of the study of the allergic illness of these, it is that we decide to carry out the surgical reduction of the size of the inferior cornetes. Among the techniques used for this purpose he/she meets the clotting with plasm argon, a procedure that uses electric current of high frequency and a source of plasm argon. The effective reduction of the cornetes, the possibility to reach it in all the longitude of these, the limited penetration, the little surgical time and the absence of complications hemorrágicas among other advantages, they make of this technique something exceptional. 40 diagnosed patients of rinitis chronic hipertrófica were assisted who were revised to the 3 months, 12 months and 24 months after the treatment. To the 24 months, 38 patients (95 percent) they referred a significant improvement of the symptoms. They are revised and the indications discuss, advantages, complications and long term results of the use of the clotting with plasm argon in rinocirugía(AU)

Mucocele de cornete medio (Concha bulosa): reporte de un caso / Mucocele of the medium turbinal bone (Balbous concha): report on one case

La presencia de un tumor endonasal como causa de obstrucción nasal crónica bilateral no es un hallazgo infrecuente. El diagnóstico diferencial de estos tumores rara vez incluye al mucocele, especialmente si éste se encuentra en una ubicación poco habitual. A continuación informamos el caso de un paciente de 18 años de edad quien consultó por obstrucción nasal crónica y ronquidos. El examen endoscópico reveló una obstrucción completa de la fosa nasal izquierda debido a una masa sólida cubierta por mucosa normal, y una desviación septal ocluyente de la fosa nasal contralateral. Durante la cirugía, los hallazgos sugirieron un gran mucocele de cornete medio, confirmado posteriormente por histopatología. El paciente fue tratado con extirpación completa del mucocele.

Mucopiocele de concha média: relato de caso

A mucopiocele de concha média é uma doença incomum. A maioria das mucoceles se situa nos seios paranasais, principalmente nos seios etmoidal e frontal. Neste trabalho descreveremos um caso de mucopiocele de concha média associada com uma pansinusopatia.

Results of temperature-controlled radiofrequency tissue volume reduction for the turbinate hypertrophy.

OBJECTIVES: To assess the efficacy of temperature-controlled radiofrequency tissue volume reduction (RFTVR) for the inferior turbinate. RESEARCH DESIGNS: Prospective, single-blinded, experimental clinical trial. METHOD: Twenty patients with nasal obstruction secondary to inferior turbinate hypertrophy were enrolled. Nasal obstruction was compared between before and after the treatment (at 1-3 days, 1 week and 6-8 weeks) of RFTVR using subjective symptom scores, physical findings and videotape images. RESULTS: Improvement of nasal symptoms was observed as early as 1 week after the operation. However, significant improvement was obtained at 6-8 weeks. CONCLUSION: RFTVR for the turbinate may be useful as an alternative approach for the treatment of chronic turbinate hypertrophy.
