BACKGROUND: Sinonasal inverted papilloma is a locally aggressive tumor arising from the Schneiderian membrane which lines the nasal cavity and paranasal sinuses. Aggressive surgical approaches, such as lateral rhinotomy, were used until recently for complete removal of the inverted papilloma. Currently, endoscopic resection is the gold standard in the treatment of inverted papilloma. However, there are situations that justify an open approach. For example there are studies that report a higher postoperative recurrence rate after endonasal endoscopic resection, particularly in the treatment of recurrent diseases...

INTRODUCTION: The mucosal cylindroma or adenoid cystic carcinoma is the second sinonasal non-epithelial malignant tumor frequency argument. Due to the achievement of the nasal mucosa and a late diagnosis reconstructions are often complex. We report the case of a mucous cylindroma recurrence of nasal septum requiring a wide and deep excision of the root of the nose with nasal reconstruction. CASE REPORT: A patient aged 66 years whose history resection two years ago with a mucous adenoid cystic carcinoma of the right side of the nasal septum, had a local recurrence T2NOM0 imposing a wide excision with amputation nasal septum own bones of nose, the anterior portion of the triangular cartilages...

Choanal polyps are a form of nasal polyps that grow toward the choana with a single stalk. Septochoanal polyp is a rare entity that originates from the mucosa of the nasal septum with choanal extension. The most common site of its origin is mainly the superior aspect of the posterior portion of the nasal septum. However, metaplastic ossification is a rare event in nasal polyp and to the best of our knowledge, septochoanal polyp with metaplastic ossification has not been reported in the literature. Herein, we report a case of huge septochoanal polyp with metaplastic ossification obstructing both the nasal cavity and nasopharynx, which was successfully removed via transnasal endoscopic approach...

BACKGROUND: Binostril endoscopic transsphenoidal approach (BETA) provides sufficient manipulation space and wide endoscopic vision, although it increases the trauma of nose. Mononostril endoscopic transsphenoidal approach (META) has minimal trauma of nose, at the expense of space within the operation. We describe a one-and-a-half nostril endoscopic transsphenoidal approach (OETA) that combines the advantages of BETA and META. METHODS: We introduced OETA for pituitary adenomas with a detailed technical description...

PURPOSE OF REVIEW: Sinonasal neoplasms have a high rate of recurrence following treatment, and clinicians utilize a variety of surveillance techniques. Generally, surveillance modality and frequency of follow-up are determined by the guidelines for head and neck cancer as a broad category. However, recent studies have demonstrated that a more tailored approach to follow-up may be necessary. RECENT FINDINGS: Endoscopy has low sensitivity in recurrence detection, especially in the asymptomatic patient...

OBJECTIVE: To determine the relationship between tumor glucose metabolism and tumor blood flow (TBF) in head and neck squamous cell carcinoma (HNSCC). METHODS: We retrospectively analyzed 57 HNSCC patients. Tumor glucose metabolism was assessed by maximum and mean standardized uptake values (SUVmax and SUVmean) obtained by 18F-fluorodeoxyglucose positron-emission tomography. TBF values were obtained by arterial spin labeling with 3-tesla MRI. The correlations between both SUVs and TBF were assessed in the total series and among patients divided by T-stage (T1-T3 and T4 groups) and tumor location (pharynx/oral cavity and sinonasal cavity groups)...

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...

The incidence of chronic otitis media with effusion (COME) after radiotherapy for nasopharyngeal or sinonasal tumors is relatively high. It is often a difficult-to-treat problem in these patients. In this retrospective study, we sought to describe the clinical course of COME in 51 patients-33 men and 18 women, aged 39 to 90 years (mean: 58.9 ± 15)-who had been referred to the Henry Ford Health System in Detroit between 2001 and 2011 for management of a tumor that had involved either the nasopharyngeal area or the sinonasal area...

Hemangiopericytomas are soft tissue tumors composed of pericytic cells that are characterized by their "staghorn" vascular branching and their variable clinical presentation. Fifteen to 25% of all HPC occur in the head and neck, with only 5% found in the nose or paranasal sinuses. Sinonasal hemangiopericytoma (SNHPC) is considered distinct from its soft tissue counterpart - the former showing a more uniform cellular organization, has convincing pericytic differentiation and is associated with a far better prognosis...

The endoscopic endonasal approach (EEA) has significantly evolved since its initial uses in pituitary and sinonasal surgery. The literature is filled with reports and case series demonstrating efficacy and advantages for the entire ventral skull base. With competence in 'minimally invasive' parasellar approaches, larger and more complex approaches were developed to utilize the endonasal corridor to create maximally invasive endoscopic skull base procedures. The challenges of these more complex endoscopic procedures include a long learning curve and navigating in a narrow corridor; reconstruction of defects presented new challenges and early experience revealed a significantly higher risk of cerebrospinal fluid leak...

The objective of this study was to investigate the value of parameters assessed with F18-FDG PET/CT in predicting recurrence-free survival (RFS) and disease-specific survival (DSS) in patients with cancer of nasal cavity and paranasal sinus. Thirty-eight patients with cancer of nasal cavity (n = 14) and paranasal sinus (n = 24) who underwent PET/CT prior to curative treatment were enrolled. A volume of interest was placed on PET/CT images covering the entire tumor volume, and the maximum SUV (SUVmax), the mean SUV (SUVmean), and volumetric parameters of metabolic tumor volume (MTV) and total lesion glycolysis (TLG) were measured using thresholds of 40 % of SUVmax...

BACKGROUND: Sinonasal undifferentiated carcinoma (SNUC) is a rare, aggressive malignancy of unknown etiology with a poor overall prognosis. Its relative rarity has made it difficult to determine the impact of different treatment modalities on survival. METHODS: Retrospective study of cases in the National Cancer Data Base (NCDB). NCDB cases that were diagnosed as having SNUC between January 1, 2004, and December 31, 2013 were included in the analysis. Outcomes of patients treated with surgery followed adjuvant chemoradiotherapy were compared with definitive chemoradiotherapy...

BACKGROUND: Sinonasal carcinomas (SNCs) comprise various rare tumor types that are characterized by marked histologic diversity and largely unknown molecular profiles, yet share an overall poor prognosis owing to an aggressive clinical course and frequent late-stage diagnosis. The lack of effective systemic therapies for locally advanced or metastatic SNC poses a major challenge to therapeutic decision making for individual patients. We here aimed to identify actionable genetic alterations in a patient with metastatic SNC whose tumor, despite all diagnostic efforts, could not be assigned to any known SNC category and was refractory to multimodal therapy...

BACKGROUND: The infraorbital nerve (ION) is a terminal branch of the maxillary nerve (V2) providing sensory innervation to the malar skin. It is sometimes necessary to sacrifice the ION and its branches to obtain adequate maxillary sinus exposure for radical resection of sinonasal tumors. Consequently, patients suffer temporary or permanent paresthesia, hypoestesthia, and neuralgia of the face. We describe an innovative technique used for preservation of the ION while removing the anterior, superior, and lateral walls of the maxillary sinus through a medial endoscopic transnasal maxillectomy...
