There is a lack of consensus regarding the necessity of performing in-office nasal debridement and the majority of clinicians carry out their postoperative care according to experience and their own preference. This is often determined by the extent of surgery performed, the severity of the postoperative inflammation, as well as being dependent on the patient's discomfort, the time constraints associated with postoperative care and the costs associated with additional appointments. Ideally, nasal debridement should be performed by the operating surgeon under endoscopic control both gently and atraumatically.

The first European Rhinology Research Forum organized by the European Forum for Research and Education in Allergy and Airway Diseases (EUFOREA) was held in the Royal Academy of Medicine in Brussels on 17th and 18th November 2016, in collaboration with the European Rhinologic Society (ERS) and the Global Allergy and Asthma European Network (GA2LEN). One hundred and thirty participants (medical doctors from different specialties, researchers, as well as patients and industry representatives) from 27 countries took part in the multiple perspective discussions including brainstorming sessions on care pathways and research needs in rhinitis and rhinosinusitis. The debates started with an overview of the current state of the art, including weaknesses and strengths of the current practices, followed by the identification of essential research needs, thoroughly integrated in the context of Precision Medicine (PM), with personalized care, prediction of success of treatment, participation of the patient and prevention of disease as key principles for improving current clinical practices. This report provides a concise summary of the outcomes of the brainstorming sessions of the European Rhinology Research Forum 2016.

Objectives/Hypothesis:Lateral cephalometry has been widely used to characterize facial and maxillary morphology in obstructive sleep apnea (OSA) patients. It is a useful tool to assess orthodontic and maxillofacial procedures, but transverse dimensions of the airway (e.g., nasal framework) have not been well described yet by cephalometry. We explored whether postero‐anterior cephalometry could refine the analysis of the facial morphology, with a special attention paid to nasal morphology. We validated cephalometric measurements relevant to the diagnosis of OSA.Study Design:Controlled study.Methods:We explored postero‐anterior and lateral cephalometric bony structures in OSA patients and in control subjects to determine which were predictive of an association with OSA. Healthy volunteers paired for age and sex to OSA patients underwent polysomnography and cephalometry. Data were analyzed by Shapiro‐Wilk, Fisher, Wilcoxon, and paired t tests where appropriate.Results:Nasal fossae and maxillary bone proportions were positively and independently associated with the absence of OSA. Measurements of maxillary width, nasal fossae angle, and anterior skull base contributed to the characterization of OSA patients.Conclusions:Postero‐anterior cephalometry is an easy, rapid, informative, and reliable technique, which is complementary to the lateral cephalometry in the assessment of OSA patients. Our study may also suggest the negative impact of the nasal resistance on the upper airway resistance in sleep disorders. Laryngoscope, 2012

OBJECTIVE In a device based on midsagittal jaw movements analysis, we assessed a sleep-wake automatic detector as an objective method to measure sleep in healthy adults by comparison with wrist actigraphy against polysomnography (PSG). METHODS Simultaneous and synchronized in-lab PSG, wrist actigraphy and jaw movements were carried out in 38 healthy participants. Epoch by epoch analysis was realized to assess the ability to sleep-wake distinction. Sleep parameters as measured by the three devices were compared. This included three regularly reported parameters: total sleep time, sleep onset latency, and wake after sleep onset. Also, two supplementary parameters, wake during sleep period and latency time, were added to measure quiet wakefulness state.RESULTS The jaw movements showed sensitivity level equal to actigraphy 96% and higher specificity level (64% and 48% respectively). The level of agreement between the two devices was high (87%). The analysis of their disagreement by discrepant resolution analysis used PSG as resolver revealed that jaw movements was right (58.9%) more often than actigraphy (41%). In sleep parameters comparison, the coefficient correlation of jaw movements was higher than actigraphy in all parameters. Moreover, its ability to distinct sleep-wake state allowed for a more effective estimation of the parameters that measured the quiet wakefulness state.CONCLUSIONS Midsagittal jaw movements analysis is a reliable method to measure sleep. In healthy adults, this device proved to be superior to actigraphy in terms of estimation of all sleep parameters and distinction of sleep-wake status.

Background: Nasal olfactory mucosa is an accessible source of olfactory ensheathing cells for spinal cord regeneration. However, safety of the biopsy technique and the effects on sense of smell and nasal function have not been robustly assessed in the form of a prospective controlled study. Methodology: National Health Service ethical approval was granted for this study of 131 patients. The primary outcome measure was olfactory function and the secondary outcomes included postoperative complication rates as well as the SNOT 22, NOSE scale scores and surgeon reported (Lund-Kennedy score) nasal function outcomes. Results: 65 patients underwent functional endoscopic sinus surgery (FESS) and superior turbinate biopsy, and 66 patients underwent FESS only as the control group. There was no significant difference in complication rates between the two groups. All Olfactory function outcomes were unaffected following olfactory biopsy. We demonstrated that the patients quality of life and nasal patency as well as surgeon reported outcome measurements remain unaffected following olfactory harvesting. Conclusions: We have uniquely provided level 2a evidence for the safety of endoscopic biopsy of olfactory mucosa, which does not affect nasal function or the sense of smell compared to standard FESS without biopsy.
