Gustatory Function in Patients With Cerebellopontine Angle Masses.

Objective: To investigate the impact of cerebellopontine angle (CPA) masses on subjective and measured taste function.

Study Design: Retrospective cross-sectional study.

Setting: Tertiary referral center.

Olfactory Fluctuation Revisited.

Objectives: Many patients complain about olfactory fluctuation (OF), which is a symptom commonly attributed to sinonasal disease. Data-based evidence for its association with sinonasal disease is scarce. The aim of the study is to identify explanatory variables associated with OF and to analyze its predictive value regarding sinonasal disease.

Olfactory and Gustatory Function in Patients With Different Types of Maxillofacial Trauma.

Objectives/hypothesis: To investigate olfactory and gustatory function in patients with maxillofacial trauma and associated fractures.

Study Design: Retrospective cohort study.

Methods: Olfactory and gustatory function was assessed psychophysically in 124 patients who had sustained maxillofacial trauma with an associated fracture.

Chemosensory decrease in different forms of olfactory dysfunction.

The aim of this study is to investigate the effect of olfactory dysfunction (OD) on the two other chemical senses, namely gustation and the intranasal trigeminal system. Taste and trigeminal function were analyzed in a retrospective cross-sectional study of 178 participants with OD (n = 78 posttraumatic, n = 42 idiopathic, n = 27 post-infectious and n = 31 chronic rhinosinusitis (CRS) OD). All patients had been investigated for OD at our smell and taste outpatient clinic.

Olfactory function improves following hemodialysis.

Olfactory function has been shown to be affected in chronic kidney disease; however, studies are contradictory and little is known on the effects of dialysis. To resolve these issues we tested olfactory function in 24 healthy controls and in 28 patients with chronic kidney disease receiving hemodialysis (20 patients) or peritoneal dialysis (the other 8). As assays for olfactory function we measured smell identification, n-butanol and acetic acid thresholds, Kt/V urea, percentage reduced urea, and weights before and after dialysis.

Olfactory disorders: the patients' view.

Objective: To investigate the level of knowledge that patients had about their olfactory disorder at the time of presentation to a specialist Olfaction Clinic.

Design: Multi-centered, cohort study of consecutive patients presenting to specialist Olfaction Clinics surveyed using a standardized questionnaire.

Setting: Tertiary referral Olfactory Clinics in Geneva, Switzerland and Dresden, Germany.

Retronasal olfactory function in Parkinson's disease.

Objectives/hypothesis: Orthonasal olfaction is severely altered in PD patients. Retronasal olfactory function has been shown to be preserved under certain conditions even in the absence of orthonasal function. This study was undertaken to investigate retronasal versus orthonasal olfactory function in Parkinson's disease (PD).

Gustatory function after microlaryngoscopy.

Conclusion: Quantitative gustatory alterations are rare after microlaryngoscopy (MLS), whereas transient qualitative taste distortions occur more often. Patients undergoing MLS should know that mild but transient qualitative taste disorders may occur.

Objective: Suspension MLS requires neck extension and tongue compression.

Retronasal olfactory function in nasal polyposis.

Objective: To investigate the question of whether there is a difference in retronasal olfactory function between patients suffering from chronic rhinosinusitis with nasal polyposis (NP) and healthy controls. This question was based on the clinical observation that many of these patients present with smell loss without complaining about loss of the appreciation of foods.

Study Design: Open prospective study comparing symptomatic patients with healthy controls.
