Management of isolated sphenoid sinus disease in children: a surgical perspective

Isolated Sphenoid Sinus Disease in Children

The rarity of isolated sphenoid sinus disease (ISSD) and the specificity of pediatric populations meant that a separate analysis was required in this study. This study aimed to present and discuss the results of an analysis of clinical manifestations, radiological findings and surgical methods based on a large series of exclusively pediatric patients. The study group covered 28 surgically treated children (aged 5.5-17.5 years). The medical data were retrospectively analyzed and meticulously discussed with regards to presenting signs and symptoms, radiographic findings, surgical approaches, complications, post-op care, histopathological results and follow-ups. The dominant symptom was a persistent headache (78%). Four children presented visual symptoms, diplopia in two cases, visual acuity disturbances in one case and both of these symptoms in one patient. Sixteen children presented chronic isolated rhinosinusitis without nasal polyps, six suffered from mucocele and one presented chronic sphenoiditis with sphenochoanal polyp. Four patients turned out to exhibit neoplastic lesions and developmental bony abnormality was diagnosed in one case. No fungal etiology was revealed. The transnasal approach was used in 86% of patients. A transseptal approach with concurrent septoplasty was used in four patients. The patient with visual acuity disturbances completely recovered after the surgery. All children with visual symptoms reported improvement in the vision immediately after surgery. No postoperative complications were observed. Fungal etiology was extremely rare in the pediatric population with ISSD. The surgical treatment should be a minimally invasive procedure regarding a limited range of the pathology in ISSD. Emergency surgery should be performed if ISSD produces any visual loss.

Acute isolated sphenoid sinusitis in children: A case series and systematic review of the literature

OBJECTIVE

This study aims to present a case series and systematic review of acute isolated sphenoid sinusitis (AISS) in children in order to better characterize clinical presentation, diagnosis, treatment, and outcomes of this condition.

DATA SOURCES

Ovid MEDLINE, Pubmed, Embase, Cochrane Library, and Google Scholar.

STUDY SELECTION

Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Full-text, peer-reviewed journal publications from 1994 to 2020 in English; focus on acute sphenoid sinusitis; pediatric patients (<18 years of age); series with two or more children. Studies were assessed for data including demographics, presenting symptoms and signs, radiological investigations, treatment, outcomes and complications.

RESULTS

Ten studies identifying 71 patients were included. Average age at presentation was 12.0 years (range 5-17 years). M:F ratio 1:1. The most common presenting symptoms were headache (98.6%), fever (50.7%), nasal symptoms (22.5%) ocular symptoms (19.7%) and decreased level of consciousness (12.7%). Twenty patients (28.1%) had neurological signs. Twenty-three patients (32.4%) presented with headache in isolation. Unsuspected diagnosis at presentation was noted in 54.0%. Average time to initial presentation was 14.0 days (median = 5.5 days, range 1-90 days). The majority of children were treated with antibiotics (98.6%) with 31.0%, 2.8% and 2.8% also undergoing sinus surgery, revision sinus surgery and neurosurgery, respectively. Intracranial complications occurred in 16.9% of patients. Significant long term sequelae occurred in 2 children (2.8%) and one death (1.4%) was also reported.

LIMITATIONS

All studies were retrospective case note reviews.

CONCLUSIONS

Acute sphenoid sinusitis is a rare and difficult condition to diagnose in children. The majority of patients make a full recovery with appropriate treatment. If treatment is delayed however consequences can be life-threatening.

Two Cases of Acute Isolated Sphenoid Sinusitis in Children

Acute isolated sphenoid sinusitis is a rare disease, and accounts for less than 3% of all sinusitis, especially in young children. Delayed diagnosis or misdiagnosis can occur frequently due to atypical clinical presentations. This can lead to serious complications because of the involvement of anatomically related intracranial structures. Therefore, nasal endoscopy, computed tomography (CT), and magnetic resonance imaging (MRI) are important diagnostic tools to confirm the diagnosis. We report two cases of a previously healthy 6-year-old girl and a 13-year-old boy, whose chief complaints were uncontrolled headache and high fever over 38°C. Physical examination and initial laboratory test results of blood, urine, and cerebrospinal fluid were normal. The diagnosis was made after a brain MRI revealed isolated sphenoid sinusitis. The girl was treated with third generation cephalosporins intravenously. The boy, however, had to undergo an emergent endoscopic sinus surgery as his headache and eyeball-pain symptoms did not resolve by medical treatment alone. Both cases had good outcomes, without neurological sequelae.

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.

Isolated sphenoid sinus opacification: A systematic review

OBJECTIVE

Unilateral sphenoid sinus opacification (SSO) on imaging is a common incidental radiologic finding. Inflammatory sinus disease is rarely isolated to one sinus cavity therefore SSO raises the potential for neoplastic etiology. The clinical significance of SSO was evaluated and compared to maxillary sinus opacification (MSO).

METHODS

A systematic review of unilateral sinus opacification was performed via Medline (1966-January 12th, 2015) and Embase (1980-January 12th, 2015), limited to English literature and human subjects. Case series of patients treated with radiologic evidence of unilateral sinus opacification either from maxillary or sphenoid sinuses and with pathology results were included. Individual cases were classified as neoplastic, malignant, or a condition requiring surgical intervention (i.e. fungal ball). Exclusion criteria were single case reports, lack of primary data, series of complications, or single pathology series. Case-by-case analysis was performed for both SSO and MSO.

RESULTS

Search strategy revealed 3264 studies. A total of 31 studies including 1581 patients met the inclusion criteria. In these studies, SSO was described in n=1215 (76.9%) and MSO in n=366 (23.1%). For SSO, the final diagnosis was neoplasia 18%, (malignancy in 10.9%). 58.3% of cases required surgical intervention and 13% were inflammatory. For MSO, neoplasia represented 18.3% (malignancy 7.1%), surgical intervention required in 47% of cases and 27.6%. were inflammatory.

CONCLUSION

Isolated MSO and SSO is a marker of neoplasia in 18% and malignancy in 7-10% of patients presenting with these radiologic findings. Clinicians should be wary of conservative management given the high incidence of neoplasia and consider a lower threshold for early surgical intervention.

Comprehensive review on endonasal endoscopic sinus surgery

Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinus surgery with extended surgery of the frontal (Draf type III), maxillary (grade 3-4, medial maxillectomy, prelacrimal approach) and sphenoid sinus. In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving. This article gives a comprehensive review on the most recent state of the art in endoscopic sinus surgery according to the literature with the following aspects: principles and fundamentals, surgical techniques, indications, outcome, postoperative care, nasal packing and stents, technical equipment.
