Tumours affecting the nose, paranasal sinuses and adjacent skull base are fortunately rare. However, they pose significant problems of management due their late presentation and juxtaposition to important anatomical structures such eye and brain. The increasing application of endonasal endoscopic techniques to their excision offers potentially similar(More)
The incidence of head and neck squamous cell carcinoma (HNSCC) has been gradually increasing over the last three decades. Recent data have now attributed a viral aetiology to a subset of head and neck cancers. Several studies indicate that oral human papillomavirus (HPV) infection is likely to be sexually acquired. The dominance of HPV 16 in HPV+ HNSCC is(More)
BACKGROUND Nasal polyposis (NP) is not a life-threatening disorder but may have a great impact on the quality of life (QoL). The objective of this study: (i) to investigate the health burden incurred by NP compared with the Spanish general population using the Short Form-36 Health Survey (SF-36) questionnaire; (ii) to compare the QoL outcome after medical(More)
BACKGROUND Because of the increase in indications for laser surgery to treat malignant tumors of the larynx and hypopharynx, a higher number of complications may be expected. We prospectively evaluated the frequency and characteristics of intraoperative and postoperative complications of early and advanced tumors of the larynx and hypopharynx treated with(More)
OBJECTIVES Smell tests for clinical use have been developed in different countries, but no single test has gained general acceptance. The objectives of the study were to evaluate the smell outcomes in a Spanish population. METHODS A prospective study on healthy volunteers (n = 120) without olfactory disturbances was performed. The volunteers were(More)
Chronic rhinosinusitis (CRS) including nasal polyps is a chronic inflammatory disease of the nasal and paranasal sinus mucosa that, despite differing hypotheses of its cause, remains poorly understood. Primary symptoms are nasal blockage, loss of smell, rhinorrhea, and facial pain or pressure. Chronic rhinosinusitis causes significant physical symptoms, has(More)
BACKGROUND Although various relationships between the lower and upper airways have been found, the association of bronchiectasis with chronic rhinosinusitis and nasal polyps has not been thoroughly evaluated. This study was undertaken to examine the association of idiopathic and postinfective bronchiectasis with chronic rhinosinusitis and nasal polyposis.(More)
The advent of endoscopic sinus surgery led to a resurgence of interest in the detailed anatomy of the internal nose and paranasal sinuses. However, the official Terminologica Anatomica used by basic anatomists omits many of the structures of surgical importance. This led to numerous clinical anatomy papers and much discussion about the exact names and(More)
BACKGROUND There are sufficient reports on the incidence of complications after endonasal surgery of the paranasal sinuses. It is the aim of this study to calculate the incidence of typical complications after primary and revision surgery, after "functional" and "extended" operations, together with the influence of expertise and of different optical devices(More)
BACKGROUND The objective of this study was to evaluate the outcomes of transoral laser microsurgery (TLM) in T3 laryngeal carcinomas and to identify prognostic factors for survival and laryngeal preservation. METHODS This study aimed to provide a retrospective analysis of 147 consecutive patients, evaluating their overall survival, disease-specific(More)
