Visual Acuity Impairment from Inflammatory Isolated Sphenoid Sinus Disease.

BACKGROUND/AIM: To investigate the treatment outcomes and determinants of prognosis in patients experiencing visual acuity (VA) deterioration due to inflammatory isolated sphenoid sinus disease (ISSD) who underwent endonasal endoscopic surgery (EES). PATIENTS AND METHODS: Thirteen patients with 14 lesions treated with EES between March 2010 and April 2022 were included. Evaluation included improvements in VA using the logarithm of the minimum angle of resolution (LogMAR) scale, resolution rates of associated symptoms, and identification of factors predicting VA recovery. A literature review was conducted to assess the outcomes for ISSD-related VA impairments. RESULTS: The most common etiology is mycetoma (n=5), followed by an equal representation of mucocele and sphenoiditis (n=4). The mean interval from symptom onset to intervention was 4.7 months, with an average follow-up duration of 14.4 months. Seven eyes exhibited preoperative VA of 2.1 LogMAR or worse, with diplopia/ptosis (n=8) and headache (n=5) being the predominant co-occurring symptoms. After surgery, all ancillary symptoms improved, with an overall VA recovery rate of 87.5% (improvement more than 0.2 logMAR units). Mucocele exhibited the best improvements, whereas sphenoiditis showed the least progress (p=0.021). Poor baseline VA (p=0.026) and combined diplopia/ptosis (p=0.029) were identified as negative prognostic factors for VA recovery. CONCLUSION: Our findings suggest a favorable prognosis for VA recovery following EES in patients with inflammatory ISSDs, with response variations based on disease entity. However, further research is needed to personalize therapeutic strategies for enhanced outcomes.

[Methods of surgical treatment for isolated lesions of the sphenoid sinus]. / Metody khirurgicheskogo lecheniya pri izolirovannom porazhenii klinovidnoi pazukhi.

This article presents an analytical review of scientific publications on the topic of surgical treatment of isolated lesions of the sphenoid sinus. The publications, research data presented in the RSCI database, PubMed in the period 1985-2021 are analyzed. The selection of the material was carried out according to the keywords: sphenoid sinus, isolated sphenoiditis, phenotypes of sphenoiditis, endoscopic sphenotomy, relapses of sphenoiditis, sphenoid sinus, isolated sphenoiditis, phenotypes of sphenoiditis.

Complications of Isolated Fungal Sphenoiditis: Patient Clinical Characteristics.

OBJECTIVE: To evaluate the clinical characteristics of patients with complications of isolated fungal sphenoiditis. MATERIALS AND METHODS: The records of patients diagnosed with isolated fungal sphenoiditis at Songklanagarind Hospital from January 2004 to December 2017 were retrospectively reviewed. Data related to demographics, clinical presentation, underlying disease, type of complication, surgical procedure, and clinical outcome were collected. RESULTS: Among the 35 participating patients, complications were found at a rate of 40%. The most common complication was visual loss (71.43%). We also compared the clinical characteristics between patients with and without complications via univariate analysis. The enrolled patients consisted of 12 men and 23 women (1:2). The mean age was older in the complications group 64 (41-84) vs. 57.43 (36-81) years, respectively. Underlying diabetes mellitus and complete opacity of the sphenoid sinus were factors that related significantly to the occurrence of complications. After treatment, 35.72% of the participants made a complete recovery; underlying diabetes mellitus was associated with a poor prognosis. CONCLUSION: This report indicates that practitioners must be careful of complications arising in elderly and female patients with isolated fungal sphenoiditis, who have a complete opacity of the sphenoid sinus and underlying diabetes mellitus.

Endoscopic Treatment of Isolated Sphenoid Sinus Disease in Children.

In this article, we explore the disease spectrum and clinical characteristics of and the diagnosis and endoscopic approach to treating isolated sphenoid sinus disease (ISSD) in children. To these ends, we review a case series of 19 patients (mean age: 8.1 ± 4.9 years, range: 1.1-15 years, median age: 6.7 years, 13 males, 6 females) who underwent surgical treatment at our hospital for ISSD during the 4 years between 2012 and 2016. The symptoms of pediatric sphenoid sinus disease tend to be variable and nonspecific and include atypical headache, nasal congestion, epistaxis, postnasal drip, snoring, and impaired vision. Headache is the presenting symptom in 42% of patients, but headaches occurred in no specific or typical location. Ten patients underwent preoperative endoscopic examination, and abnormalities in the sphenoethmoidal recess were found in 6 (60%) of these 10 patients. All 19 patients underwent ultra-low-dose paranasal sinus computed tomography (CT) imaging, and 9 patients with suspected tumors or sphenoid mucoceles were further examined by magnetic resonance imaging (MRI). The endoscopic transostial approach was performed in all 19 patients: 16 patients received excision of inflammatory sphenoid sinus disorders and benign tumors, including sphenoid sinusitis, sphenoid sinus mucocele, sphenoid sinus polyp, and ossifying fibroma; 3 patients with suspected tumors received biopsies to detect rhabdomyosarcoma, Langerhans cell histiocytosis, and juvenile xanthogranuloma. No intraoperative or immediate postoperative complications were observed. Children with opacified sphenoid sinus identified by radiographic imaging presented a variety of pathologies. The most common lesions were associated with inflammatory disease. Because the symptoms of pediatric sphenoid sinus disease tend to be variable and nonspecific, CT remains the standard for evaluating sphenoid sinus disease, and ultra-low-dose paranasal sinus CT imaging is recommended and can provide images of equal or better quality compared with those obtained by standard dose CT. In addition, MRI is an essential adjunct in the diagnosis and selection of treatment for suspected tumors of the sphenoid sinus. The endoscopic transostial approach was especially suitable for the management of pediatric benign isolated sphenoid sinus lesions.

Nocardial clival osteomyelitis secondary to sphenoid sinusitis: an atypical skull base infection.

Clival osteomyelitis is a life-threatening complication of untreated malignant otitis externa or paranasal sinus infection. Although various pathogens have been implicated, to our knowledge, primary nocardial clival osteomyelitis has never been reported. We describe a 74-year-old woman who presented with headaches, abducens and hypoglossal nerve palsies, facial numbness, photophobia, and neck stiffness. Imaging revealed a heterogeneous mass within the sphenoid sinus with clival extension. The lesion was extirpated via a binostril endoscopic endonasal transsphenoidal approach. Histopathological and microbiological examination revealed a nocardial source. Clival osteomyelitis associated with sphenoid sinusitis should be included in the differential diagnosis of progressive skull base lesions in the setting of an underlying infection. Early recognition and intervention with antibiotics and surgical debridement is essential in the management of this rare entity.

Scedosporium apiospermum invasive sinusitis presenting as extradural abscess.

INTRODUCTION: Chronic invasive fungal rhinosinusitis (CIFR) is a rare entity generally observed in immunodepressed subjects. The pathogen most frequently identified is Aspergillus spp. Imaging generally reveals invasive pseudoneoplastic features. We report a case of Scedosporium apiospermum (S. apiospermum) CIFR with an atypical clinical and radiological presentation. CASE REPORT: A 72-year-old immunocompetent man presented with chronic headache, neck pain and bilateral limitation of lateral gaze. Imaging revealed an isolated left sphenoidal lesion with marked bone changes and an extradural abscess over the clivus. Large endoscopic sphenoidotomy with type II rhinopharyngectomy was performed and the diagnosis of S. apiospermum CIFR was based on histological examination and fungal culture. The patient refused all medical treatment and did not present any signs of recurrence after 1 year of follow-up. DISCUSSION: S. apiospermum is a fungal species rarely isolated in CIFR. The present case was revealed by an atypical clinical presentation including isolated sphenoidal infection complicated by bilateral abducens nerve paralysis and extradural abscess. Imaging was also unusual, revealing features of fibrous dysplasia or bacterial osteomyelitis rather than the typical pseudoneoplastic appearance. The patient was successfully treated by surgery alone, which may therefore be sufficient treatment in immunocompetent subjects.

Can Volumetric and Morphological Variants of Sphenoid Sinuses Influence Sinuses Opacification?

Improvements in computed tomography and in functional endoscopic sinus surgery have recently increased interest toward paranasal sinus anatomy and anatomic variations that can be observed in patients affected by sinusitis. Isolated sphenoid sinusitis is a relatively rare pathology, often related to nonspecific symptoms, therefore making diagnosis difficult. The correlation between this type of sinusitis and anatomical variants remains unclear.The authors' aim was to retrospectively revise paranasal sinuses computed tomography scans of patients affected by sphenoid sinusitis, compared with a control group, analyzing the types of sphenoid sinus and the presence of aberrant pneumatization, and performing a segmentation of the sphenoid sinuses to calculate the volumes.Sphenoid sinuses of 60 patients affected by sinus opacification, compared with a control group, were segmented. Type of sinus (sellar, presellar, postsellar) and presence of aberrant pneumatization were assessed as well. Possible statistically significant differences in volumes according to sex and group were assessed through 2-way ANOVA test (P < 0.05). Post-hoc test was assessed through Student t test. χ test was applied in order to verify the statistically significance of differences in frequency of different types of sinus pneumatization variants (P < 0.05).Average volume of sphenoid sinuses in males was of 7.672 cm and of 7.751 cm in females within the group of patients; statistically significant differences in volume were found according to sex (P: 0.342), but not between the patients and control group (P: 0.0929). Post-hoc test verified that males affected by sinus opacification showed smaller volumes in comparison with the control males (P < 0.05). In addition, patients by affected sinus opacification showed more frequently the postsellar type and were less affected by pneumatization variants of the sphenoid bone than the control group (P < 0.05).This study first suggests the possible protective role of variants of pneumatization in the development of sphenoid sinus opacification.

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.

Prospective study on the outcome of the sphenoid drill out procedure.

BACKGROUND: Chronic sphenoid sinusitis refractory to both medical therapy and sphenoidotomy requires a more extended intervention based on the principles of salvage surgery. Our aim is to describe the sphenoid drill out technique as a sphenoid salvage intervention and to outline its implications on clinical outcome and quality of life. METHODOLOGY: 12 patients with chronic sphenoiditis undergoing a sphenoid drill out procedure were examined by nasal endoscopy preoperatively and postoperatively for one year. Preoperative and postoperative quality of life questionnaires (RSOM-31 and SF-36) were obtained. RESULTS: All but one patient had a completely patent neostium without scar formation. No major complications occurred after this procedure. All patients reported at least an improvement of their symptoms, 50% of patients were even symptom free at one year after surgery. The median postoperative RSOM-31 score was significantly lower than the preoperative score. Both the physical component summary (PCS) and the mental component summary (MCS) of the SF-36 score improved significantly. None of the patients needed a revision procedure. CONCLUSION: Sphenoid drill out is a safe and effective technique with a high success rate. In patients with chronic sphenoid sinusitis refractory to medical therapy and surgery it could be a valid alternative to revision sphenoidotomy.

Isolated sphenoid sinus fungus ball: a retrospective study conducted at a tertiary care referral center in Korea.

Fungus ball (FB) is the most common form of extramucosal fungal rhinosinusitis involving one or more paranasal sinuses. The sphenoid sinus is an uncommon site of this disease. Here, we present our 20-year experience of managing isolated sphenoid sinus FB (SSFB). We retrospectively reviewed a series of 47 cases of isolated SSFB encountered between 1996 and 2015 with reference to the chronological incidence, demographics, clinical features, radiological findings, treatment modalities, and outcome. Recently, the number of patients with isolated SSFB has increased markedly. The mean age of the patients in this study was 63.1 years (range 26-84 years), and there was significant female predominance. The most common symptom was headache (72.3%), which was localised in various regions. On the other hand, nasal symptoms presented at a relatively low rate. On computed tomography, the most common findings were total opacification, calcification, and sclerosis of the bony walls. There was no significant difference in the presence of SSFB between the ipsilateral and contralateral sides of the nasal septal deviation and concha bullosa. Magnetic resonance imaging demonstrated an isointensity on T1-weighted images and marked hypointensity on T2-weighted images. Treatment consisted of endonasal endoscopic sphenoidotomy with complete removal of the FB. The prognosis was good, with no recurrence after a mean follow-up of 13.2 months. Isolated SSFB is a rare disease, but its prevalence is increasing. Although the clinical presentation is usually vague and nonspecific, SSFB should be considered in patients with unexplained headache, especially in elderly women. Endoscopic sphenoidotomy is a reliable treatment with low morbidity and recurrence rates.

Results of transnasal transostial sphenoidotomy in 79 cases of chronic sphenoid sinusitis.

OBJECTIVE: This study was designed to retrospectively review the postoperative results of transnasal transostial sphenoidotomy in 79 patients with isolated chronic sphenoid sinusitis operated between 1995 and 2013 and evaluate the recurrence rate due to postoperative closure of the sphenoidotomy. PATIENTS AND METHODS: Seventy-nine patients, 44 women and 35 men (M:F sex ratio: 0.79) aged 10 to 84 years (mean age: 48), were included. The most common presenting symptom was headache in 61% of cases. Visual disturbances were present in three cases. The diagnostic work-up comprised nasal endoscopy, computed tomography (CT) and magnetic resonance imaging (MRI) of the sinuses. The surgical indication was based on failure of antibiotic therapy and/or the nature and severity of sphenoid sinusitis. All patients were operated by endoscopic transnasal transostial sphenoidotomy. Samples were taken for histological, bacteriological and mycological examination. RESULTS: No intraoperative or immediate postoperative complications were observed. Nature of the lesion: forty-seven patients (59.5%) presented nonspecific inflammatory lesions with negative bacterial or fungal culture and inflammatory mucosal changes, 19 patients (24%) had fungal sinusitis presenting as a fungus ball and 13 patients (16.4%) had documented bacterial sinusitis. Mean postoperative follow-up was 7.4 months (range: 6-48). No recurrence of the sinusitis or symptoms was observed in 71 cases (89.8%). Recurrence: eight cases (10.2%) of postoperative closure of the sphenoidotomy were observed, requiring one (6 cases) or several (2 cases) reoperations with a mean of 16.4 months after the initial procedure. Symptoms of recurrence consisted of varying degrees of headache, with similar symptoms to those of the first episode in 7 cases, and retro-orbital headache in 1 case. Reoperation was performed via a transnasal transostial approach in 6 cases and a transethmoidal approach in 2 cases. CONCLUSION: The transnasal transostial surgical approach is a safe and effective procedure for the treatment of isolated sphenoid sinusitis. However, the recurrence rate due to postoperative closure of the sphenoidotomy observed in our series raises the question of postoperative maintenance of a patent and functional sphenoidotomy.

Cavernous sinus thrombosis secondary to aspergillus granuloma: A case report and review of the literature.

Cavernous sinus thrombosis is a rare but serious complication of sphenoid aspergillosis. The rarity of this pathology makes its diagnostic very difficult on a clinical, biological and radiological sense. The authors present a case of cavernous sinus thrombosis with ipsilateral internal carotid artery thrombosis secondary to a non-invasive sphenoid aspergillosis in an immunocompetent host, responsible of a cavernous syndrome associated to a Claude Bernard Horner syndrome. One year after surgery, the patient is still asymptomatic without recurrence. Diagnostic modalities are detailed and several management of this pathology are compared. Surgery is essential in a diagnostic and therapeutic sense. There is no evidence of the interest of adjuvant therapies such as antibiotic and anticoagulation. Concerning the antifungal treatment, the attitude towards a non-invasive sphenoid aspergillosis in an immunocompetent host is unclear.

Fungus ball of the paranasal sinuses: Analysis of our serie of patients. / Bola fúngica sinusal: análisis de nuestra casuística.

INTRODUCTION AND OBJECTIVES: The fungus ball is the most frequent type of fungal rhino-sinusitis. The objective of this study is to analyze the clinical and surgical features of our patients. METHODS: Retrospective analysis of 35 patients with fungus ball treated in our centre between 2006 and 2014. RESULTS: Mean age was 55 years old. 49% were men and 51% women. 75% involved the maxillary sinus, whereas 25% involved the sphenoid. 69% of our patients showed microcalcifications in the CT study. All the patients were surgically treated, with no cases of recurrence. CONCLUSIONS: Clinical manifestations of fungus ball are non-specific, therefore endoscopy and image study are mandatory. The definitive diagnosis is made by histopathological study of the lesion. Endoscopic sinus surgery is the treatment of choice, with opening of the diseased sinus and complete removal of the fungus ball. The frequency of complications is very low. No oral or topical antimycotic treatments are necessary.

Unilateral isolated sphenoid sinusitis with contralateral abducens nerve palsy - A rare complication treated in a low-resource setting.

BACKGROUND: Unilateral isolated sphenoid sinus disease (ISSD) is a rare diagnosis of the paranasal sinuses that can be associated with complications involving vascular, neurologic, and optic structures in close proximity. CASE PRESENTATION: A 62 year old female presented to a hospital in Georgetown, Guyana with right lateral rectus palsy, diplopia, and a severe progressively worsening headache. CT scan revealed an opaque left sphenoid sinus consistent with unilateral ISSD. A transnasal sphenoidotomy was performed without complication under local anesthetic in the absence of endoscopic guidance. The patient's headache resolved immediately after surgery while the diplopia and lateral rectus palsy resolved completely after 6 weeks. CONCLUSION: We present a rare complication of ISSD and highlight challenges associated with diagnosis and management of ISSD in a resource-limited setting. This is the second reported case of unilateral ISSD with contralateral lateral rectus palsy in the literature.
