Alternativa terapéutica para mejorar la calidad de vida en pacientes con fibrosis quística y discinesia ciliar primaria / Therapeutic alternative to improve quality of life in patients with cystic fibrosis and primary ciliary dyskinesia

Objective: To evaluate the clinical response of patients with cystic fibrosis and primary ciliary dyskinesia after endoscopic sinus surgery at the Dr. Robert Reid Cabral Children's Hospital from September 2021 to February 2022. Methods: An ambispective, cross-sectional, observational case series study was conducted, where the study population was made up of patients with cystic fibrosis and primary ciliary dyskinesia at the Dr. Robert Reid Cabral children's hospital during the study period. Inclusion criteria: Patients older than 6 years with a confirmed diagnosis of cystic fibrosis and primary ciliary dyskinesia (Genetic test with 2 homozygous mutations, positives electrolytes in sweat), severe respiratory symptoms of CRS that did not improve with conventional treatment and underwent endoscopic surgery for sinuses. Results: Of a total of 41 patients, only 10 met the inclusion criteria, the most prevalent age range was 14 to 18 years. Both CF and PCD patients decreased the frequency of CRS symptoms. After ENC, there were discrete changes in lung function, and only patients with severe to moderate disease increased % of FEV1. Most of the patients did not require admission after surgery. The most common germ found in nasopharyngeal and sputum cultures in preoperative patients was Pseudomonas aeruginosa in 86%; after ESS there was a significant increase in MRSA colonization in both CF and PCD patients. More than 50% of postoperative patients improved their quality of life, so endoscopic sinus surgery is effective in this population in the treatment of chronic rhinosinusitis.

Objetivo: Evaluar la respuesta clínica de los pacientes con fibrosis quística y discinesia ciliar primaria posterior a la cirugía endoscópica de senos paranasales en el Hospital Infantil Dr. Robert Reid Cabral en el período septiembre 2021 a febrero 2022. Métodos: Se realizó un estudio observacional tipo serie de casos, de corte transversal y ambispectivo, donde la población estudiada estuvo conformada por los pacientes con fibrosis quística y discinesia ciliar primaria del hospital infantil Dr. Robert Reid Cabral en el período de estudio. Criterios de inclusión: Pacientes mayores de 6 años con diagnóstico confirmado de fibrosis quística y discinesia ciliar primaria (Prueba genética con 2 mutaciones homocigotas, electrolitos en sudor positivos), síntomas respiratorios severos de RSC que no mejoraron con tratamiento convencional y sometidos a la cirugía endoscópica de senos paranasales. Resultados: De un total de 41 pacientes, sólo 10 cumplieron con los criterios de inclusión, el rango de edad más prevalente fue de 14 a 18 años. Tanto los pacientes con FQ como los de DCP disminuyeron la frecuencia de los síntomas de RSC. Posterior a la CEN hubo cambios discretos en la función pulmonar, y sólo los pacientes con enfermedad grave a moderada aumentaron el % de FEV1. La mayoría de los pacientes no ameritaron ingresos posterior a la cirugía. El germen más común encontrado en los cultivos nasofaríngeo y esputo en los pacientes preoperatorios fue la Pseudomonas aeruginosa en el 86%, luego de la CEN hubo un aumento significativo de la colonización por MRSA tanto en los pacientes con FQ como en los de DCP. Más del 50% de los pacientes postquirúrgicos mejoraron su calidad de vida, por lo que la cirugía endoscópica de senos paranasales es efectiva en dicha población en el tratamiento de la rinosinusitis crónica.

Hematoma subperiosteal orbitário secundário a barotrauma em aviação civil / Orbital subperiosteal hematoma secondary to barotrauma in civil aviation

RESUMO Os diagnósticos diferenciais que compõem as proptoses agudas são, muitas vezes, desafiadores. A anamnese e o exame clínico exigem do oftalmologista atenção especial aos detalhes que permitem diferenciar quadros relativamente benignos e autolimitados de quadros que evoluirão com incapacidades permanentes. Relatamos o caso de uma paciente de 49 anos que, durante viagem de avião, apresentou dor ocular, hematoma periorbitário e proptose do olho esquerdo súbitos. Referia diplopia aguda incapacitante. Exames de tomografia e angiorressonância magnética confirmaram diagnóstico de sinusopatia do seio etmoidal esquerdo e hematoma subperiosteal da órbita esquerda, associado ao barotrauma. Apesar de raro, o diagnóstico de hematoma subperiosteal não traumático deve ser considerado diferencial em relação a proptoses agudas, sendo a anamnese fundamental para essa elucidação diagnóstica.

ABSTRACT Differential diagnoses of acute proptosis are often challenging. History and clinical examination require from ophthalmologists special attention to details, which make it possible to differentiate relatively benign and self-limited conditions from those that will progress to permanent disabilities. We report a 49-year-old female patient who had sudden eye pain, periorbital hematoma and proptosis of the left eye during a commercial flight. She also complained of disabling acute diplopia. Computed tomography and magnetic resonance angiography imaging confirmed the diagnosis of subperiosteal hematoma of the left orbit, associated with left ethmoid sinus disease. Although rare, non-traumatic subperiosteal hematoma should be considered in differential diagnoses of acute proptosis, and history taking is fundamental to elucidate the picture.

Anatomical variations of the maxillary sinus septa of an Iranian population using cone-beam computed tomography: a retrospective study / Variaciones anatómicas de los tabiques del seno maxilar de una población iraní mediante tomografía computarizada de haz cónico: estudio retrospectivo

This study sought to assess the internal anatomy of the maxillary sinuses and their septa using cone-beam computed tomography (CBCT) in an Iranian population. Materials and Methods: Resorption of alveolar bone decreases the height of the maxillary alveolar ridge. This height reduction may be so severe that it warrants ridge augmentation by a sinus lift. Manipulation of the maxillary sinuses, as in sinus lift surgery, requires adequate knowledge about the sinus anatomy.Results: Maxillary sinus septum, as an anatomical variation, may complicate the surgical procedures and increase the risk of complications such as sinus membrane perforation. In this retrospective study, 366 sinuses, 190 from females and 176 from males, aged between 10 and 65 years old presenting to the Oral and Maxillofacial Radiology Department of School of Dentistry at Hamadan University of Medical Sciences were evaluated by two oral radiologists. The extension of the maxillary sinuses, presence of septa, number of septa and their location were determined. Data were analyzed using the chi square test (level of significance p≤0.001). The coefficient of agreement between the two oral radiologists was calculated based on Cohen kappa. Septa were present in 40.5% of the maxillary sinuses, out of which, 31.6% had one, 7.9% had two and 1% had three or more septa; 38% of the septa were horizontal while 62% had an oblique orientation. In total, 184 septa were found in 183 patients; out of which, 91 septa were 2mm to 5mm long while 93 septa were longer than 5mm. Conclusions: Comprehensive knowledge about the three-dimensional internal anatomy of the maxillary sinuses acquired by CBCT priorto surgical procedures can greatly help to prevent postoperative complications.

Este estudio buscó evaluar la anatomía interna de los senos maxilares y sus septos mediante tomografía computarizada de haz cónico (CBCT) en una población Iraní. Materiales y Métodos: . La resorción del hueso alveolar disminuye la altura de la cresta alveolar maxilar. Esta reducción de altura puede ser tan severa que justifique el aumento de la cresta mediante una elevación de seno. La manipulación de los senos maxilares, como en la cirugía de elevación del seno, requiere un conocimiento adecuado sobre la anatomía del seno. Resultado: El tabique del seno maxilar, como una variación anatómica, puede complicar los procedimientos quirúrgicos y aumentar el riesgo de complicaciones como la perforación de la membrana sinusal. En este estudio retrospectivo, dos radiólogos orales evaluaron 366 senos, 190 de mujeres y 176 de hombres, con edades comprendidas entre 10 y 65 años que se presentaron en el Departamento de Radiología Oral y Maxilofacial de la Facultad de Odontología de Hamadan University of Medical Sciences. Se determinó la extensión de los senos maxilares, la presencia de septos, el número de septos y su ubicación. Los datos se analizaron mediante la prueba de chi cuadrado (nivel de significación p?0.001). El coeficiente de concordancia entre los dos radiólogos orales se calculó en base a Cohen kappa. Los septos estaban presentes en el 40.5% de los senos maxilares, de los cuales, el 31.6% tenía uno, el 7.9% tenía dos y el 1% tenía tres o más septos; El 38% de los septos eran horizontales, mientras que el 62% tenía una orientación oblicua. En total, se encontraron 184 septos en 183 pacientes; de los cuales, 91 septos tenían de 2mm a 5mm de largo, mientras que 93 septos tenían más de 5mm. Conclusion: El conocimiento exhaustivo sobre la anatomía interna tridimensional de los senos maxilares adquiridos por CBCT antes de los procedimientos quirúrgicos puede ayudar en gran medida a prevenir complicaciones postoperatorias.

Radiologic study of the nasal septal swell body and its relationship to septal deviation

Objective@#To compare the radiographic features of the nasal septal swell body (NSB) with the laterality of nasal septal deviation and investigate whether there is a correlation between the severity of the septal deviation and difference in NSB size.@*Methods@#Design: Retrospective Observational Study. Setting: Tertiary Private University Hospital. Participants: 30 paranasal sinus computerized tomography scans from January to October 2017.@*Results@#A septal deviation was present in 60% of the subjects. In 78% of cases with septal deviation, the NSB was noted to be significantly larger on the side opposite the nasal septal deviation (p < .05). @*Conclusion@#The correlation between the severity of the septal deviation and difference in NSB size had a value of (r = 0.37) therefore, no positive correlation was established. Subjects with almost symmetric NSB measurements tend to have no septal deviation. On the other hand, the NSB is more prominent contralateral to a septal deviation.

Trombosis del seno cavernoso derecho secundaria a rinosinusitis esfenoidal: reporte de caso / Right cavernous sinus thrombosis secondary to sphenoidal rhinosinusitis: case report

RESUMEN La rinosinusitis bacteriana aguda es la infección de la mucosa nasal y de senos paranasales, que se manifiesta con congestión nasal, rinorrea purulenta y fiebre, de curso generalmente autolimitado. La trombosis del seno cavernoso (TSC) es una complicación poco frecuente, que se asocia a compromiso del seno esfenoidal y etmoidal, manifestándose clínicamente con cefalea, fiebre, alteración de pares craneanos y síntomas oculares. Ante su sospecha el estudio imagenológico es fundamental. En estos exámenes se debe buscar un defecto de llene en el seno cavernoso comprometido. El tratamiento debe iniciarse de forma precoz y contempla: antibioticoterapia, drenaje quirúrgico del seno afectado y anticoagulación. Se presenta a un paciente pediátrico masculino con TSC derecha posterior a una rinosinusitis esfenoidal no tratada, que respondió favorablemente al tratamiento. Se describe la clínica y manejo de esta patología, que presenta alta morbimortalidad, y que puede disminuirse considerablemente con un tratamiento precoz y agresivo.

ABSTRACT Acute bacterial rhinosinusitis is the infection of the nasal and paranasal mucous membrane, with symptoms such as nasal congestion, purulent rhinorrhea and fever, usually self-limiting. Cavernous sinus thrombosis (CST) is a rare complication, which is associated with sphenoid and ethmoid sinus involvement, clinically manifest with headache, fever, cranial nerve involvement and ocular symptoms. When suspected, imaging studies will confirm the clinical impression. They will show abnormal flow parameters in the compromised cavernous sinus. The treatment has to start as soon as possible and consists in broad spectrum intravenous antibiotics, surgical drainage of the site of the infection and anticoagulation. We present a patient with a right CST secondary to a non-treated sphenoidal sinusitis, that responded favorably to treatment. The clinical and management of this pathology is described, which presents a high morbidity and mortality that can be reduced considerably with an early and aggressive treatment.

Mucocele: Clinical Characteristics and Outcomes in 46 Operated Patients

Abstract Introduction Paranasal sinus mucocele is a benign, expansive lesion associated with paranasal sinus obstruction. It affectsmostly adults, and ismost 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 sinusmucocele. Themean 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 sinusmarsupialization; 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. (AU)

An Emergent Entity: Indolent Mucormycosis of the Paranasal Sinuses. A Multicenter Study

Abstract Introduction Indolent or chronic mucormycosis is a rare entity that affects both immunosuppressed and immunocompetent individuals. Additionally, its clinical evolution is nonspecific and there is no standardized treatment for this condition. Objective To describe the clinical characteristics and management of patients with indolent mucormycosis. Methods In the project of study with chart review in the Interinstitutional secondary care centers, patients with evidence of indolentmucormycosis, defined as pathological confirmation of nasal/paranasal sinus mucormycosis for more than 1 month, were included. All patients underwent complete laboratory workup, imaging studies, surgical treatment and adequate follow-up. No evidence of disease status was defined when patient had subsequent biopsies with no evidence of mucormycosis. Results We included seven patients, three female and four male subjects. The mean age was 53.14 years. Four patients were immunosuppressed and three immunocompetent. Among the immunosuppressed patients three had diabetes and one had dermatomyositis. The symptomswere nonspecific: facial pain/headache, mucoid discharge and cacosmiawere the ones most frequently reported. Maxillary sinus involvement was present in all patients. Two immunosuppressed subjects received amphotericin. Posaconazole was the only treatmentinoneimmunosuppressedpatient. Allimmunocompetent patientshadsingleparanasal sinus disease and received only surgical treatment. All patients are alive and free of disease. Conclusion Indolent mucormycosis is a new and emerging clinical entity in immunosuppressed and immunocompetent patients. Single paranasal sinus disease is a frequent presentation and should not be overlooked as a differential diagnosis in these patients. Immunocompetent patients should only be treated surgically. (AU)

Comparison of cone-beam computed tomography and panoramic radiography in the evaluation of maxillary sinus pathology related to maxillary posterior teeth: Do apical lesions increase the risk of maxillary sinus pathology?

PURPOSE: The aims of this study were first, to compare panoramic radiography with cone-beam computed tomography (CBCT) for evaluating topographic relationships, such as the classification of maxillary posterior teeth and their distance to the maxillary sinus floor; and second, to determine the relationship between maxillary sinus pathology and the presence of apical lesions. MATERIALS AND METHODS: In total, 285 paired CBCT and panoramic radiography records of patients (570 maxillary sinuses) were retrospectively analyzed. Both imaging modalities were used to determine the topographic relationship of the maxillary posterior teeth to the sinus floor. Mucosal thickening >2 mm was considered a pathological state. Data were analyzed using the chi-square, Wilcoxon, and Mann-Whitney U tests. Odds ratios (ORs) and confidence intervals (CIs) were calculated. RESULTS: The closest vertical distance measurements made between posterior maxillary teeth roots and the maxillary sinus on panoramic radiography and CBCT scans showed statistically significant differences from each other (P<0.05). Compared to panoramic radiography, CBCT showed higher mean values for the distance between the maxillary sinus floor and maxillary posterior teeth roots. The CBCT images showed that at least 1 apical lesion adjacent to the right maxillary sinus increased the risk of maxillary sinus pathology by 2.37 times (OR, 2.37; 95% CI, 1.58-3.55, P<0.05). CONCLUSION: Panoramic radiography might lead to unreliable diagnoses when evaluating the distance between the sinus floor and posterior roots of the maxillary teeth. Periapical lesions anatomically associated with maxillary sinuses were a risk factor for sinus mucosal thickening.

Bola fúngica de cavidades paranasales: serie de casos / Fungus ball of the paranasal sinuses: case series

RESUMEN Introducción La bola fúngica (BF) es una sinusitis fúngica no invasiva, con acumulación extramucosa de conglomerados densos de hifas de hongos en cavidades paranasales (CPN), afectando generalmente a mujeres inmunocompetentes. Objetivo Describir la presentación cínica, diagnóstico y tratamiento de una serie de pacientes con diagnóstico de BF de CPN. Material y método Estudio descriptivo retrospectivo de pacientes con diagnóstico histopatológico de BF sometidos a cirugía endoscópica nasal (CEN) en nuestra institución entre 2010 y 2016. Resultados Se incluyeron 20 pacientes (15 mujeres, 5 hombres), con edad promedio al diagnóstico de 64 años (35-86 años), la mayoría inmunocompetente (85%). El síntoma más frecuente fue dolor facial (8/20). Todos los pacientes fueron estudiados con tomografia computarizada (TC) de CPN, presentando calcificaciones en 70%. La ubicación más frecuente fue el seno maxilar (12/20) y luego esfenoidal (6/20). Se realizó CEN en todos los pacientes, combinándolo con Caldwell Luc en 3 de ellos. Los cultivos intraoperatorios resultaron negativos en el 75% de los pacientes. Conclusión La BF tiene presentación cínica inespecifica. Se sospecha en base a hallazgos imagenológicos en la TC de CPN y se confirma histopatológicamente, dado el bajo rendimiento de los cultivos. La CEN es la herramienta diagnóstico-terapéutica de elección, con baja tasa de recidiva local.

ABSTRACT Introduction A fungus ball (FB) is a non-invasive fungal sinusitis, consisting of extramucosal accumulation of dense fungal hyphae conglomerates, located in paranasal sinuses. It generally affects immunocompetent women. Aim To describe the clinical presentation, diagnosis and treatment in a series of patients diagnosed with FB of paranasal sinuses. Material and method Retrospective descriptive study regarding all patients with a histopathologic diagnosis of FB, who underwent endoscopic sinus surgery (ESS) in our institution between 2010 and 2016. Results Twenty patients (15 women, 5 men) were included, with a mean age at diagnosis of 64 years (35-86 years). Most were immunocompetent (85%). Facial pain was the most frequent symptom (8/20). All patients were studied with a sinus CT, finding paranasal calcifications in 70%. It predominantly involved the maxillary (12/20), and sphenoid sinus (6/20). All patients were treated with ESS, with a combined Caldwell Luc approach in only 3 of them. Intraoperative cultures were negative in 75% of patients. Conclusions Sinus FB has a non-specific clinical presentation. CT findings help suspect it, and it is confirmed with a histopathological study, given the poor efficiency of cultures. ESS is the diagnostic-therapeutic procedure of choice, with a low local recurrence rate.

Atelectasia maxilar crónica bilateral con resolución espontánea / Bilateral chronic maxillary atelectasis with spontaneous resolution

RESUMEN La atelectasia maxilar crónica (AMC) es una condición adquirida y rara que consiste en la disminución persistente y progresiva del volumen del seno maxilar, con retracción centrípeta de sus paredes secundaria a la oclusión completa de tipo valvular del ostium natural. Esta condición genera presión negativa dentro del seno maxilar, conduciendo a atelectasia y colapso de la pared. La fisiopatología es compartida con síndrome de seno silente, por lo que se postula que se podrían englobar a ambas dentro de la misma enfermedad. Presentamos el caso de un paciente con diagnóstico de AMC bilateral por tomografía axial computarizada a la edad de 3 años, que se resolvió en forma espontánea en forma bilateral; el maxilar derecho a los 6 años y el izquierdo a los 10 años.

ABSTRACT Chronic maxillary atelectasis (CMA) is a rare and developed condition that consists in the progressive and persistent decrease volume of the maxillary sinus, with centripetal retraction of the walls secondary to the complete occlusion of the natural ostium. This condition generates negative pressure inside the maxillary sinus, heading to atelectasis and collapse of the walls. It is proposed that the disease includes the silent sinus syndrome, as the physiopathology is shared between them. We present the case of a 3 years old boy with bilateral chronic maxillary atelectasis observed in the CT scan, who evolved with spontaneous bilateral resolution. The right maxillary sinus CMA resolved at 6 years old, and the left at 10 years old.

Caracterización epidemiológica, clínica y tomográfica de pacientes con afecciones no traumáticas de los senos paranasales / Clinical, epidemological and tomographic characterization of patients with non traumatic disorders of the paranasal sinuses

Se realizó una investigación observacional, descriptiva y transversal de 132 pacientes con afecciones no traumáticas de los senos paranasales, atendidos en el Servicio de Otorrinolaringología del Hospital Provincial Docente Saturnino Lora Torres de Santiago de Cuba, desde enero del 2013 hasta diciembre del 2015, a fin de caracterizarles según variables epidemiológicas, clínicas y tomográficas de interés. En la serie predominaron los afectados de 39-58 años de edad (42,4 por ciento), el hábito de fumar (62,1 por ciento) y las infecciones dentarias (59,1 por ciento) como los principales factores de riesgo, así como los procesos inflamatorios sinusales (62,1 por ciento) que afectaron preferentemente el seno maxilar. Se halló coincidencia entre el diagnóstico definitivo y los signos tomográficos en 66 pacientes, con un coeficiente de Kappa de 0,80.

An observational, descriptive and cross-sectional investigation of 132 patients with non traumatic disorders of the paranasal sinuses, assisted in the Otolaryngology Service of Saturnino Lora Torres Teaching Provincial Hospital in Santiago de Cuba, was carried out from January, 2013 to December, 2015, in order to characterize them according to clinical, epidemiological and tomographic variables of interest. In the series there was a prevalence of the affected patients aged 39-58 (42.4 percent), the smoking habit (62.1 percent) and dental infections (59.1 percent) as the main risk factors, as well as the sinusal inflammatory processes (62.1 percent) that preferably affected the maxillary sinus. There was a coincidence between the definitive diagnosis and the tomographic signs in 66 patients, with a Kappa coefficient of 0.80.

Abstract Report of a clinical case of ocular proptosis related to ethmoidal mucocele, the case is rare and ocular involvement is not commonly related in the literature. We also emphasize its clinical presentation and the treatment instituted. W.L.S., male, 27 years old from Fortaleza-CE. He presents to the HUWC outpatient clinic complaining of low visual acuity perceived for 10 days in the right eye (OD). The ophthalmologic exam showed a best corrected visual acuity of 20/200 OD and 20/20 left eye (OS), absence of abduction and elevation of OD with light ptosis (distance margin 1 - 2 mm) and diplopia when looking to the right. Proptose OD of moderate aspect axial aspect (24mm). Biomicroscopy slit lamp without changes. Intraocular pressure: 18mmHg OD 12 mmHg OS. Background of eye: OD discrete pallor disk appearance, no other changes and OS within normality. A CT scan was performed that showed presence of a rounded lesion in the ethmoidal sinus area penetrating the bone wall of the OD orbit suggestive of ethmoidal mucocele. Forwarded to the otorhinolaryngology service of the HUWC, being submitted to endoscopic surgical procedure etmoidectomy. One month after the surgical procedure visual acuity of OD 20/25, present and symmetrical ocular movements, absence of diplopia and persistence of mild pallor in OD. Expansion of mucocele may occur over many years or rapidly. Ocular involvement with low visual acuity is uncommon as the first symptom, when it occurs it deserves immediate treatment. Surgical treatment is generally indicated in the case and should be instituted as soon as possible for adequate visual recovery.

Hypoplastic maxillary antra

Background: Maxillary sinus hypoplasia is an uncommon pathology of the paranasal sinuses, which might be encountered in the clinical practice. Computed tomography scan confirms its existence and any associated anatomical anomaly and variations that might coexist

Objective: To present three cases of maxillary sinus hypoplasia which were diagnosed and managed surgically

Design: A Retrospective Study

Setting: Otorhinolaryngology Department, Bahrain Defence Force Hospital, Bahrain

Method: Three cases of maxillary sinus hypoplasia were managed from January 2012 to December 2015. The clinical presentation, radiological findings and surgical management of these patients were documented and found to be distinct from other cases

Result: The first case was a fourteen-year-old male with long-standing nasal symptoms, which were not relieved by medical treatment. Sinus CT scan revealed an ill-defined infundibular passage and complete opacified small right maxillary sinus; CT was classified as hypoplasia type 2 according to Bolger et al and was successfully treated surgically

The second case was a twenty-seven-year-old male with persistent left sided facial heaviness and left-sided headache. Sinus CT scan revealed left side normal uncinate process with well-defined infundibular passage indicating type 1 maxillary sinus hypoplasia

The third case was a thirty-four-year-old pregnant female with diplopia and left-sided headache. MRI revealed left maxillary sinus and inferiorly displaced left orbital floor with non-homogenous fluid-like signal intensity suggesting marked left long-standing sinusitis

The patient was managed by an antral lavage under local anesthesia. After delivery, she was reassessed by CT scan of the sinuses, which revealed left side small sized partial opacified type 2 maxillary sinus hypoplasia

Conclusion: Symptomatic maxillary sinus hypoplasia patients with a diseased blocked ostiomeatal complex have special diagnostic considerations and therapeutic challenges

Mucocele maxilar secundario a cirugía ortognática: reporte de un caso / Maxillary mucocele after an orthognathic surgery: case report

El mucocele es un tumor pseudoquístico poco frecuente en el seno maxilar y una rara complicación de la cirugía ortognática. El caso reportado describe la presentación de un mucocele que afecta parcialmente el seno maxilar y se presenta clínicamente como un tumor nasal. Se trata de una mujer de 44 años que, luego de 12 años de realizarse cirugías ortognáticas, presenta dolor facial y obstrucción de la fosa nasal derecha. La tomografía axial computarizada de senos paranasales revela una masa de contenido líquido que ocupa la mitad inferior del seno maxilar derecho, extendiéndose a la fosa nasal ipsilateral. La paciente es intervenida por vía endoscópica realizándose una marsupialización intranasal y meatotomía media, evolucionando satisfactoriamente en un seguimiento de dos años.

Mucoceles are not often found in the maxillary sinus, and is a rare surgery complication, in this case, orthognathic. This review describes a mucocele that partially occupies the right maxillary sinus, causing a chronic nasal obstruction. This is the case of a 44 year-old female patient, which after 12 years of several orthognathic surgeries, presents facial pain and right nasal obstruction. The paranasal sinus computed tomography reveals a mass with liquid content that occupies the lower part of the right maxillary sinus and compromises the right nasal cavity. The patient was treated with an intranasal marsupialization and a middle meatotomy with endoscopic nasal approach. Evolution was satisfactory two years after the intervention.
