Background  Most existing objective surgical motion analysis schemes are limited to structured surgical tasks or recognition of motion patterns for certain categories of surgeries. Analyzing instrument motion data with respect to anatomical structures can break the limit, and an anatomical region segmentation algorithm is required for the analysis. Methods  An atlas was generated by manually segmenting the skull base into nine regions, including left/right anterior/posterior ethmoid sinuses, frontal sinus, left and right maxillary sinuses, nasal airway, and sphenoid sinus...

Central nervous system (CNS) infections due to filamentous basidiomycetes are extremely rare. We encountered a case of epidural abscess due to Schizophyllum commune that extended from sinusitis. A 53-year-old Japanese man presented at our hospital with a headache. Computed tomography (CT) of the cranium and sinuses showed ethmoid and sphenoid sinusitis with no intracranial abnormalities. The patient was diagnosed with acute sinusitis and underwent antibiotic treatment. However, the symptoms deteriorated, and the patient came to our hospital again with consciousness disturbance...

BACKGROUND: Secondary cerebrospinal leaks (CSF) are leaks that recur after an initial endoscopic repair of CSF leaks. Identification of characteristics that could predict secondary leaks may allow surgeons to plan repairs with the knowledge that these defects are more likely to fail. OBJECTIVE: To identify characteristics that could predict secondary CSF leaks. METHODS: A search of all studies that reported outcomes after endoscopic repair of CSF leaks was conducted by using medical literature data bases...

A 64 year-old man with pituitary adenoma developed massive epistaxis after an uneventful endoscopic transsphenoidal surgery. Angiography showed extravasation from the sphenopalatine artery, to which embolisation was performed. An incidentally coexisting ethmoidal dural arteriovenous fistula supplied by the ophthalmic artery aberrantly originated from the middle meningeal artery caused increased haemorrhage.

Maxillary cysts, including the cysts lined by respiratory epithelium, can present a diagnostic challenge. We report an unusual case of a maxillary cyst on an endodontically treated tooth #16, in which the cavity was totally lined by a respiratory epithelium. The patient, a 35-year-old male, presented with a generalized chronic periodontitis and complained of a pain in the tooth #16 region. A periodontal pocket extending to the root apices with pus coming out from the gingival was found. A combined endodontic periodontal was observed on a panoramic radiography...

Nuclear protein in testis (NUT) carcinoma is a rare malignant neoplasm with an undifferentiated morphology. Its diagnosis is often difficult, especially as the sinonasal tract gives rise to many tumors with undifferentiated morphologies. Not many cases of sinonasal NUT carcinomas have been reported, and its clinicopathological features have not been sufficiently clarified. In this study, we performed a clinicopathological study of 4 patients with sinonasal NUT carcinoma, including wide-ranging immunohistochemical tests and cytogenetic analyses using fluorescence in situ hybridization and DNA sequencing...

The olfactory cleft is the specific site of development of many tumours (respiratory epithelial adenomatoid hamartoma, intestinal-type adenocarcinoma, neuroblastoma, inverted papilloma, glomangiopericytoma, etc.) and is also the site of CSF rhinorrhoea via the cribriform plate (cribri-rhinorrhoea). Olfactory cleft surgery must therefore be considered to be a specific type of surgery, complementary to ethmoidal labyrinth surgery and anterior skull base surgery. Olfactory cleft tumours can be resected according to five different surgical procedures: olfactory cleft mucosal resection, partial resection of the olfactory cleft, total resection of the olfactory cleft, unilateral endoscopic anterior skull base resection, and bilateral endoscopic anterior skull base resection...

The objective of the present work was to study the relationship between the dimensions of the ethmoidal labyrinth and the skull in the subjects differing in the nose shape by means of the factorial and correlation analysis with the application of the modern computer-assisted methods for the three-dimensional reconstruction of the skull. We developed an original method for computed craniometry with the use the original program that made it possible to determine the standard intravital craniometrics characteristics of the human skull with a high degree of accuracy based on the results of analysis of 200 computed tomograms of the head...

INTRODUCTION: Inverted papillomas (IP) are benign sinonasal neoplasms, which account for 0.5-4% of all nasal tumors. IPs have been known to transform into squamous cell carcinoma in 5-15% of cases. Rarely, transformations to other malignancies have been reported. Here we report a unique case of malignant transformation of an IP into sinonasal undifferentiated carcinoma (SNUC). METHODS: A case report with a literature review; institutional review board exempted. The clinical presentation, radiographic features, surgical intervention, histopathologic analysis, treatment, and outcome of the case were examined...

OBJECTIVES: Ethmoid punch sinusotomy (EPS) is a feasible treatment for ethmoid sinusitis in a subset of chronic rhinosinusitis (CRS) patients per a recent report. This adjunctive work investigates the technical characteristics of EPS and determines if EPS measurably alters the topical delivery of irrigant into the ethmoid sinuses in a cadaveric model. METHODS: The sinonasal cavities of 10 human cadaver heads were irrigated with a solution containing methylene blue and radio-opaque contrast prior to and following EPS...

Sarcoma is an uncommon histopathological presentation of sinonasal tumors, comprising ~15% of all cases; liposarcoma is particularly uncommon. An analysis of the available medical literature revealed no prior reports of dedifferentiated liposarcoma (DDLPS) of the sinonasal cavity. This case report presents a rare case of DDLPS of the sinonasal cavity. A 40-year old six-week pregnant female was admitted with a left nasal obstruction. Endoscopic evaluation of the left nasal cavity revealed a polypoid lesion. A computed tomography scan indicated a mass invading the left nasal cavity, maxillary sinus and anterior ethmoid sinus with focal destruction of the surrounding bone...

BACKGROUND: Orbital exenteration is a radical surgical procedure resulting in deformity. It involves removal of the globe, optic nerve, extra-ocular muscles, orbital fat, lacrimal gland, and peri-osteum. Sino-orbital fistula (SOF) formation is a common documented post-operative complication, usually connecting the orbit and the ethmoid sinus. SOFs can cause leaks of serous fluid, and act as an entry site for pathogens into the orbit leading to socket infection and breakdown. METHODS: This retrospective study analyzed exenterations performed over a 22-year period (1993-2015) at the National Ocular Oncology Service Centre for Scotland...

PURPOSE: Paranasal sinusitis is widespread and can lead to orbital complications, blindness, and death. However, the correlation between ophthalmological findings and disease staging remains unclear. This study aimed to investigate the staging, acute ophthalmological manifestations, diagnosis, management, and outcomes of orbital complications of paranasal sinusitis during a 27-year period. METHODS: We retrospectively reviewed the medical records of all patients with orbital complications of paranasal sinusitis hospitalized at the National Cheng Kung University Hospital, a medical center in Taiwan during 1988-2015...

Esthesioneuroblastoma is a rare malignant tumour of the olfactory epithelium. The most common symptom is related to unilateral nasal obstruction. It rarely presents with bilateral proptosis and blindness. We report a 21-month-old girl with esthesioneuroblastoma in sphenoid and ethmoid sinus in a child presenting with bilateral proptosis, blindness, and irritability. The diagnosis was confirmed by histopathology.

Natural killer/T-cell lymphomas are extremely rare and carry high mortality rates. Epidemiologically, these cancers tend to affect mainly Asian and South American patients and are associated with Epstein-Barr virus seropositivity. This report details a 78-year-old Vietnamese woman who presented initially with vitritis of unknown cause, but later developed proptosis and conjunctival involvement as her disease spread. Biopsies of the orbit, ethmoid sinus, and conjunctiva were found to be significant for natural killer/T-cell lymphoma...
