Sino-nasal smooth muscle tumours of uncertain malignant potential (SMTUMP) are very rare neoplasms of mesenchymal origin with features in between a benign leiomyoma and a leiomyosarcoma. We report a rare case of SMTUMP in a 44-year-old woman, who presented with vague symptoms of pharyngitis. Nasal endoscopy revealed a smooth mass in left nasal cavity. Contrast-enhanced CT and MRI scans showed features likely to be inverted papilloma or olfactory neuroblastoma or meningioma. Excision was planned and intraoperatively, frozen section revealed a probable spindle cell lesion...

BACKGROUND: Chordomas are rare malignant tumours of the axial skeleton and skull base supposed to arise from cellular remnants of the notochord. These tumours have the potential to metastasize (30-40 %), usually in the later course of the disease. However, the greatest morbidity is usually a result of loco-regional recurrence with infiltration and destruction of surrounding bone and soft tissue. Patients with unresectable or metastatic chordoma are faced with a poor prognosis since cytotoxic chemotherapy or other systemic therapies have not proven their efficacy yet...

Sinonasal tumors are rare neoplasms with distinctive clinical, aetiological and pathological features. The diagnosis and treatment of these tumours is challenging because of their low incidence, histological diversity and production of non-specific symptoms in the early stages. They have a variable prognosis depending on their histology, origin and staging. Their location, close to neurocritical structures, which are of special relevance to surgery and postoperative treatment, makes their treatment difficult and complex, leading to high morbidity and mortality...

Neurofibroma is a slow growing benign tumour of the peripheral nerve sheath which is frequently associated with neurofibromatosis type 1 (Prakash et al., 2014). Isolated solitary occurrence of neurofibroma in the maxillary sinus is rare with only 29 reported cases in the literature. We present a rare case of a 70-year-old gentleman who was referred to ENT with a right maxillary sinus neurofibroma with extension into the right inferior orbit. He has significant proptosis, ptosis, and limitation in abduction of the right eye...

A case of malignant cutaneous lesion of the face diagnosed initially as sebaceous carcinoma, subsequently proven to be squamous cell carcinoma is presented. Patient was initially evaluated at an outside institution by computed tomography, which indicated extension of lesion to the maxillary sinus. Patient underwent local resection. Further imaging by magnetic resonance imaging was done for recurrent tumour. Examination revealed extensive, large volume, perineural extension of the disease via infraorbital nerve to the cavernous sinus...

The surgical management of skull base lesions is difficult due to the complex anatomy of the region and the intimate relations between the lesion and adjacent nerves and vessels. Minimally invasive approaches are increasingly used in skull base surgery to ensure an optimal functional prognosis. Three-dimensional (3D) computed tomography (CT) reconstruction facilitates surgical planning by visualizing the anatomical relations of the lesions in all planes (arteries, veins, nerves, inner ear) and simulation of the surgical approach in the operating position...

BACKGROUND: Since 1957, Simpson grading system is considered a predictive system for meningiomas recurrences. However, since then, there has been a great development of surgical equipment and neurosurgical technique, so the re-evaluation of this grading system should be considered. This study aims to assess if the recurrence rates and recurrence-free survivals (RFS) are different after Simpson grades I, II, and III resections in World Health Organization (WHO) grade I meningiomas METHOD: We retrospectively reviewed the data of patients who underwent surgical treatment of WHO grade I meningiomas located in convexity (group 1), falx/parasagittal (group 2), skull base, and tentorium (group 3) between June 1991 and December 2011...

INTRODUCTION: Patients with SDHx mutations need long-term radiological surveillance for the development of paragangliomas and phaeochromocytomas, but no longitudinal data exist. We assessed the performance of rapid-sequence non-contrast magnetic resonance imaging (MRI) in the long-term monitoring of patients with SDHx mutations. METHODS: Retrospective study between 2005-2015 at a University Hospital and regional endocrine genetics referral center. Clinical and imaging data of forty-seven patients with SDHx mutations [SDHB (36), SDHC (6), SDHD (5)] who had surveillance for detection of paragangliomas by rapid-sequence non-contrast MRI (base of skull to pubic symphysis) were collected...

BACKGROUND AND AIMS: Intra-operative identification and preservation of extraocular motor nerves is one of the main goals of surgeries for skull base tumours and this is done by monitoring the extraocular movement (EOM). Intra-operative electromyographic monitoring has been reported, but it is a complex and skilful process. Electrooculography (EOG) is a simple and reliable technique for monitoring EOMs. We aimed to assess the utility of EOG monitoring in preventing extraocular motor nerve dysfunction during skull base surgeries...

The objective is to assess whether free middle turbinate (FMT) graft reconstruction, after endoscopic endonasal pituitary surgery, combines an acceptably low post-operative cerebrospinal fluid (CSF) leak rate with acceptable rhinological morbidity. This study identified 50 patients who underwent endoscopic endonasal pituitary surgery by the senior author in our teaching hospital between May 2011 and June 2012. FMT graft reconstruction was used in 32 cases. 18 patients were judged pre-operatively as not suitable for FMT reconstruction according to a novel skull base reconstructive algorithm...

Intraoperative navigation systems are widely used in ENT, oral and maxillofacial, and neurosurgery. The benefits of such systems have been demonstrated in various applications, including intracranial and skull base surgery. Intraoperative shift, "brain shift" and changes in anatomy caused by the surgical procedure itself impair the accuracy of navigation and represent factors limiting its application, particularly in glioma and metastatic brain surgery. For this reason, intraoperative imaging was incorporated into neurosurgery...

BACKGROUND: Endoscopic endonasal surgery to access the anterior skull base has evolved in many centres worldwide and provides a minimally invasive alternative, with better patient experience, to open techniques. METHOD: We present a basic approach to a midline lesion that is the fundamental starting point for wider access to the skull base. CONCLUSION: The nuances of this technique illustrated here have been developed in many centres to provide a safe procedure that has a low incidence of complications and excellent potential...

Sinonasal adenocarcinomas are rare, locally invasive tumours. In this case the symptomatic profile was unusual and the diagnosis was missed at the primary care stage. Interestingly this would be the first documented case with an absent ipsilateral olfactory bulb. A 55-year old male presented with symptoms of behavioural change and mild headaches. He was later found to have a large Sinonasal adenocarcinoma which penetrated the skull base. This was treated by a combined craniotomy and endonasal approach. Sinonasal adenocarcinomas are unusual tumours and further research is required in order to clarify management strategies and prognosis...

C C Yong, A Soni-Jaiswal, J J Homer
BACKGROUND: The subcranial approach is a modification of traditional craniofacial resection. It provides similar broad access to the anterior skull base, but with lower mortality and morbidity. It has been the surgical technique of choice at our institution since 2006 for treating advanced stage sinonasal tumours (American Joint Committee on Cancer stage III or above). This paper reports our experience and outcomes. METHOD AND RESULTS: Eighteen patients underwent subcranial craniofacial resection over a seven-year period, this being combined with a second adjunctive procedure in 89 per cent of cases...

Endoscopic sinus surgery (ESS) is considered as a valid option in the management of nasal adenocarcinoma (ADC). Comparative studies with open approaches are still required. A monocentric retrospective study was carried out from May 2002 to December 2013, including 43 patients with intestinal-type adenocarcinoma of the ethmoid sinus. Non-resectable tumours or recurrences were excluded. Before 2008, open approach with lateral rhinotomy (LR) was performed as the gold standard of treatment. From 2008, ESS was systematically used as a first-line option as long as a complete resection was achievable...
