ABSTRACT Objective To report a rare case of delayed spontaneous cerebrospinal fluid (CSF) leak through clival region in the sphenoid sinus. Case report A 35-year-old female presented to our outdoor clinic with watery right nasal discharge for past 2 months, which increased on bending forward. Her medical history, general physical and neurological examinations were unremarkable. High-resolution computed tomographic scan and magnetic resonance cisternography were performed and suggestive of defect in right cribriform plate and right sphenoid sinus. Endoscopic repair was done but same symptoms occurred after 1 month. Repeat magnetic resonance imaging showed fistula in the lateral wall of right sphenoid sinus. Revision endoscopic transnasal CSF rhinorrhea repair was done. Lumbar subarachnoid drain was left in place for 5 days. No recurrence was noted at 12-week follow-up. Conclusion Endoscopic transnasal approach is the best modality of treatment for midline skull base defects. Delayed leaks can present from previously weak areas and all the doubtful areas must be examined during surgery. How to cite this article Mohindra S, Mohindra S, Joshi K, Sodhi HS.

AbstractIntroduction:Sphenoid sinus mucoceles represent only 1–2 per cent of all paranasal sinus mucoceles. Patients may present with a myriad of symptoms. Pre-operative investigations include nasoendoscopy, computed tomography and/or magnetic resonance imaging. Treatment is by endoscopic sinus surgery.Methodology:A retrospective review of the archives of the Singapore General Hospital otolaryngology department (1999–2006) identified 10 cases of sphenoid sinus mucocele. Patient demographics, presenting symptoms, investigations and treatment were evaluated.Results:The 10 patients identified (three women and seven men) had a mean age of 54.5 years (range 24–70 years). Thirty per cent of patients had a history of nasopharyngeal carcinoma treated with radiotherapy. Presenting symptoms, in order of decreasing frequency, were: ocular symptoms (50 per cent), headaches (30 per cent), nasal discharge (30 per cent) and facial pain (10 per cent). All patients underwent pre-operative computed tomography or magnetic resonance imaging. Twenty per cent of patients had evidence of intracranial involvement on imaging. All patients underwent uncomplicated transnasal sphenoidotomy and drainage of the mucocele. There was no clinical or radiological evidence of recurrence at a mean follow up of 29 months (range 4–90 months).Conclusion:Sphenoid sinus mucocele is a rare condition. In this study, radiation to the head and neck appeared to be a predisposing factor, and eye symptoms were the commonest presentation. Endoscopic sinus surgery is a safe and effective treatment modality.

ABSTRACT Ectopic glial tissue, presenting at various sites of body is a rare embryonic developmental anomaly. Very few cases are reported in adults, most being incidentally detected, revealed only by histopathological findings. One of the rarest locations is the sphenoid sinus. We present here the case of a middle aged female, presenting with spontaneous cerebrospinal fluid (CSF) rhinorrhea and meningitis. With the radiological finding of a soft tissue density in sphenoid sinus with erosion of left temporal skull base, she underwent lateral craniotomy, with excision of the mass and middle cranial fossa floor repair. Histopathology revealed a heterotopic glial tissue. Peroperative finding of a well-defined defect in the lateral wall of an extensively pneumatized sphenoid showed typical features of a patent Sternberg's canal. This case could be a living proof for the existence of this rare developmental anomaly. A persisting Sternberg's canal should be considered as the source of spontaneous CSF leaks with or without lesions in sphenoid sinuses with extensive lateral pneumatization. Most of the cases may be treated with an extended endoscopic approach. Extreme lateral lesions like this would benefit most from a craniotomy approach for proper closure of skullbase defect. Three years after successful surgery, she remains symptom free.

Encephaloceles are herniation of cranial content arising from a skull defect. Encephaloceles of the lateral wall of the sphenoid sinus (ELWSS) are  uncommon events. In most cases, these cranial hernias are secondary to trauma and craniofacial surgery. Spontaneous forms are evenrarer and not well understood. The most adopted hypothesis is a persisting Sternberg’s canal, an embryonic remnant connecting the middle cranial fossa and the nasopharynx. ELWSS are usually revealed by cerebrospinal fluid (CSF) leak. Diagnosis of this disease necessitates quick management due to the potential of lethal complications such as meningitis. We report the case of a spontaneous ELWSS in a 53-year-old woman revealed by CSF leak which was successfully managed with a conventional transcranial approach. We focus on the clinical aspect and pathogenesis of the disease, and discuss the main possible surgical approaches.

Abstract OBJECTIVE AND IMPORTANCE: Various intracranial abnormalities, including infectious conditions, may manifest as trigeminal neuralgia. CLINICAL PRESENTATION: A 33-year-old man presented with a 15-day history of right-sided facial pain and numbness. Neurological examination revealed diminished corneal reflex and facial sensation in the right V1–V2 distribution. Magnetic resonance imaging revealed a contrast-enhancing lesion centered at the right pons with extension of the enhancement to the sphenoid sinus. INTERVENTION: Broad-spectrum antibiotics were administered for 6 weeks. This resulted in alleviation of symptoms and resolution of the lesion as revealed by repeat magnetic resonance imaging. CONCLUSION: Presentation of a pons abscess with trigeminal neuralgia is rare, and to the best of our knowledge has not been reported previously. The patient was treated successfully with antibiotics alone.

ABSTRACT Objective To assess the outcomes of endonasal endoscopic repair of spontaneous cerebrospinal fluid (CSF) rhinorrhea and to analyze its possible etiological factors. Patients During the period between January 1999 and November 2011, 173 patients who presented with spontaneous CSF rhinorrhea underwent endonasal endoscopic surgery. Preoperative examination included CT scans, nasal endoscopy, measurement of glucose concentration in the nasal discharge and, in some cases, cisternographic evaluation via CT or MRI. CSF fistula closure was performed using endonasal endoscopic technique under general anesthesia. In all, 186 surgeries (173 primary attempts and 13 revisions) were carried out over the 12-year period. A combination of different plastic materials, i.e. nasal septum cartilage, facia lata, abdominal fat, rotating middle turbinate flaps, and fibrin glue was used for fistula repair. Results At the time of the surgery, sites of the CSF fistula were determined as follows: Cribriform plate—70, fovea ethmoidalis—55, sphenoid sinus—45, frontal sinus—3. Extremely pneumatized lateral extension of the sphenoid sinus was found in 26 patients, and a meningo/encephalocele protruding through the bony defect was the source of the leak in 23 of them. In terms of up to 11 years, 165 patients were treated successfully after first attempt and five more recovered after revision endoscopic surgery. Success rate after the first surgery was 95.4%, overall success rate—97.7%. There were no postoperative complications. Conclusion Possible etiological factors of this disease include obesity, innate skull base malformations, overpneumatized sphenoid sinus, particularly presence of its lateral extensions and the empty sella syndrome. Endoscopic endonasal repair of spontaneous CSF rhinorrhea appears to be a safe and successful procedure. However, technique of endoscopic closure of CSF fistulas in the lateral part of the sphenoid sinus needs further perfection.

Abstract Background: Cerebrospinal fluid rhinorrhea is a potentially life threatening condition and it is a rare emergency presentation. Most cases has been related to head trauma. However, CSF leak post COVID swab has been rarely reported.Case presentation: We report a 10 year old Emirati male, who presented to emergency department complaining of unilateral clear watery nasal discharge for 14 days, the discharge started after COVID-19 nasopharyngeal swab. The patient is a known case of 3MC syndrome and he underwent surgical repair for cleft lip and cleft palate. From the history and physical examination CSF rhinorrhea was highly suspected and nasal endoscopy confirmed the diagnosis of cribriform defect on the left side. The patient underwent surgical repair and his symptoms resolved after the surgery.Conclusion: We can conclude that COVID-19 nasopharyngeal swab has potential life threatening complications and one should consider the contraindications and the alternative methods available to detect COVID-19 to minimize the potential risks.

Objective: To describe 2 spontaneous cerebrospinal fluid (CSF) leaks complicating treatment of macroprolactinoma (MPRL) with dopamine agonist (DA) therapy. Methods: We present the 2 cases of spontaneous, DA-related CSF leaks. Prolactin levels were used to assess hyperprolactinemia. Beta-2 transferrin was tested in rhinorrhea fluid, and magnetic resonance imaging was used to assess the sella. Results: Case 1 was a 45-year-old woman with a history of MPRL, recently started on bromocriptine at 15 mg/day, presented with clear rhinorrhea, headache, and nuchal rigidity. Magnetic resonance imaging showed a large sellar lesion extending into the cavernous sinuses, posterior sphenoid sinuses, and suprasellar cistern. Computed tomography revealed areas concerning for bony erosion, likely representing leak sites, and the rhinorrhea fluid was positive for beta-2 transferrin, confirming the CSF source. Empiric antibiotics for meningitis were given and she underwent urgent neuroendoscopic, transsphenoidal CSF leak repair and debulking of the pituitary mass. Case 2 was a 55-year-old man with a 10-year history of untreated MPRL who was started on bromocriptine at 5 mg/day 2 weeks prior to admission. He presented with clear rhinorrhea and a metallic taste in his mouth, worse with the Valsalva maneuver. Imaging confirmed clinical suspicion and he was taken for surgery. A high-flow CSF leak was encountered once the tumor was debulked. This was repaired with an abdominal fat pad graft. Both patients developed diabetes insipidus and required postoperative adjuvant DA therapy. Conclusion: Spontaneous CSF leaks can complicate medical therapy of large MPRL with underlying skull defects, typically within weeks of initiation of DA. This should prompt clinicians to educate patients about the symptoms of potential CSF rhinorrhea and encourage them to promptly report them.

With the development of Neurosurgery technology, there has been a qualitative leap forward with the appearance of microanatomy, which makes the deep brain tumors which were hard to be achieved in the past, and effectively reduces the mortality of patients. Petrous apex is a cone-shaped part of the anteromedial part of the temporal bone, which is deep. It has been a challenging area for surgical anatomy for a long time. In this paper, fresh adult perfused cadaveric head specimens and dry adult cadaveric head specimens were taken as the experimental objects. The anterior wall of sphenoid sinus and the internal septum of sphenoid sinus were excised under neuroendoscope. The structures of the lateral wall of sphenoid sinus were identified and dissected. The lateral wall of sphenoid sinus and the bone of skull base were opened with micro drill, The meninges were exposed and cut open, and the related structures were dissected, observed and photographed. The experimental results show that it is relatively safe to operate in the range of less than 8mm, and the rock tip can be found accurately. The measurement of the bony structure of the skull base is helpful for the surgeon to judge the course of the internal carotid artery and its adjacent structure.

Background: The clinical presentation of sphenoid sinus meningoencephaloceles (MEC) may have insidious onset and evolution. Contemporary treatment incorporates endoscopic resection via the endonasal route.Case description: We present a case of 3 year old girl who had been complaining of permanent nasal discharge, impeded nasal breathing and difficulty with feeding since she was 5 months old. There was no history of rhinoliquorrhea. Pre-operative magnetic resonance imaging demonstrated MEC that extended from the sellar region through the non-pneumatized sphenoid sinus to the nasopharynx. The lesion was resected via endoscopic endonasal approach. Follow-up rhinoscopy confirmed the absence of post-operative cerebrospinal fluid leak.Conclusion: Endoscopic endonasal approach can be an effective and a safe treatment option for resection of congenital transsphenoidal MEC in early childhood.Keywords: Sphenoid sinus; endoscopic endonasal approach; meningoencephalocele; CSF leak; congenital.
