[Endoscopic surgical treatment of patients with isolated sphenoid sinus disease]

[A case of isolated sphenoid osteoma with suppurative sinusitis in a 15-year-old child]

Isolated sphenoid osteomas are very rare even in adults. There are extremely few publications on pediatric cases of sphenoid osteomas. This paper presents a case of isolated sphenoid osteoma combined with suppurative sphenoiditis in a 15-year-old patient. The child presented with persistent headache resistant to medical treatment. Endoscopic sphenotomy allowed both to remove osteoma and to relieve the symptoms of sinusitis. The presented case can be considered as the third detailed description of the sphenoid osteoma in children and the first demonstration of the effectiveness of the endoscopic approach for its removal.

Imaging of sino-nasal inverted papilloma: How can we emphasize the usefulness of the “striated pattern” sign?

Background

Inverted papilloma (IP) is an uncommon sino-nasal neoplasm with potentially distinctive MRI and CT features. The MR “striated” imaging pattern has been reported as a valuable MR imaging feature of IP. The purpose of this study was to validate the usefulness of this sign using detailed criteria of the sign itself.

Results

All imaging findings were described for 16 patients in descriptive pattern. The nasal involvement showed highest prevalence followed by the maxillary sinus. The bony changes include remodeling and defects (n = 6), remodeling only (n = 4), and None (n = 6). Changes were severe 1/10, moderate in 3/10, and mild 5/10. Focal hyperostosis was seen in six. A striated pattern was “diffuse” in all 16 (100%) of the IPs; it followed a certain direction in all 16 patients: divergent (n = 6), convoluted (n = 2), and parallel (n = 8). Divergent growth from focal hyperostosis was seen (n = 4). Visibility of the sign was superior in T2 images (n = 11), superior in enhanced images (n = 3), and equal in both (n = 2).

Conclusions

The striated pattern is a reliable MR imaging feature of sino-nasal IPs. Validity and usefulness of this sign can be emphasized by defining parameters of the signs itself including the following: diffusivity, direction of striations and relation to hyperostosis, and comparing visibility in both T2 and GAD-enhanced images, as well as combining this imaging signature with remolding bony changes < 1.5.

Skull base inverted papilloma: a comprehensive review

Skull base inverted papilloma (IP) is an unusual entity for many neurosurgeons. IP is renowned for its high rate of recurrence, its ability to cause local destruction, and its association with malignancy. This paper is a comprehensive review of the reports, studies, and reviews published in the current biomedical literature from 1947 to September 2010 and synthesize this information to focus on its potential invasion to the base of the skull and possible intradural extension. The objective is to familiarize the clinician with the different aspects of this unusual disease. The role of modern diagnostic tools in medical imaging in order to assess clearly the limits of the tumors and to enhance the efficiency and the safety in the choice of a surgical approach is pointed out. The treatment guidelines for IP have undergone a complex evolution that continues today. Radical excision of the tumour is technically difficult and often incomplete. Successful management of IP requires resection of the affected mucosa which could be achieved with open surgery, endoscopic, or combined approach. Radio and chemotherapy were used for certain indications. More optimally research would be a multicenter randomized trials with large size cohorts.

[Isolated inverted papilloma of the sphenoid sinus - case report]

BACKGROUND

Primary inverted papilloma of the sphenoid sinus is rare. The tumor is considered locally aggressive. In selected cases inverted papilloma can be associated with squamous cell carcinoma. Radiologic imaging is a key to an accurate diagnosis.

AIM

We analyzed patient with inverted papilloma in sphenoid sinus which was removed with endoscopic surgery.

MATERIAL AND METHODS

We discuss patient with isolated inverted papilloma located in the sphenoid sinus.

RESULTS

Performed endoscopic treatment enabled removal of tumour with no complications.

CONCLUSIONS

Transnasal endoscopic large sphenoidotomy remains an effective modality for management of patients with inverted papilloma. This method does not require external approach and it is performed with no scars, with minimal injury of tissues.

[Sphenoidotomy--the treatment of patients with isolated sphenoid sinus diseases]

INTRODUCTION

The standart terms and definitions for paranasal sinuses operations were published in 2005 by Simmen and Jones. Sphenoidotomy is a surgical procedure when the natural ostium of sphenoid sinus is enlarged in varying degrees. Microscopic, endoscopic or ballon-assisted endoscopic sphenoidotomy are performed in endonasal sinus surgery and endonasal neurosurgery. This approach is considered for cases of isolated lesions of the sphenoid sinus, the sella lesions, the cerebrospinal fluid leaks into the sphenoid sinus and also for the treatment pathological conditions in the skull base. Isolated lesions of the sphenoid sinus are very rare with uncharacteristic symptoms. Headache is the most common. Vision disturbances occur occasionally. Endoscope assisted physical examination and CT scans of paranasal sinuses are necessary to make a diagnose.

MATERIAL AND METHODS

5 patients suffering from the isolated sphenoid sinus lesion were diagnosed and treated at the Otolaryngology Department of Medical University of Lodz in 2007. Clinical data of these patients were analysed retrospectively. 4 underwent the transnasal endoscopic sphenoidotomy. There were 3 patients with chronic sinusitis, 1 with pyocele. 1 patient didn't agree for the operation.

RESULTS

All treated patients noted improvement in the preoperative symptoms. There were no complications during and after the operation.

CONCLUSIONS

Endoscopic sphenoidotomy is an effective and safe method of treatment of the isolated sphenoid sinus diseases. Nasal endoscopy and CT imaging are necessary for a precise diagnosis and treatment decision.
