RESUMEN
PURPOSE: Chronic obstructive Eustachian tube dysfunction (OETD) can lead to tympanic membrane (TM) retraction and middle ear effusion (MEE) which can cause conductive hearing impairment, which among other ear symptoms can lower the quality of life (QoL). In this prospective study we assess hearing results and subjective changes in QoL following balloon Eustachian tuboplasty (BET) in treatment of OETD. METHODS: Totally 25 ears with TM retraction and 18 ears with MEE due to chronic OETD underwent BET as the sole intervention. Outcomes including otoscopy, ability to perform the Valsalva maneuver, tympanometry, audiometry, Eustachian tube inflammation scale and the Glasgow Benefit Inventory questionnaire (GBI) were obtained on all patients preoperatively and 6 months postoperatively. RESULTS: Hearing thresholds improved statistically significantly (p < 0.05) with means of 3 dB in the TM retraction group and 9 dB in the MEE group. Total GBI results indicated a positive influence on patients' QoL. Valsalva success rate was 80% in patients with TM retraction and 67% in patients with MEE. Tympanometry results improved in 50% of TM retraction patients and in 33% of MEE patients. CONCLUSIONS: Here we demonstrated that the BET has a positive impact on patients' conductive hearing loss and QoL in patients with TM retraction or MEE. Results were better in TM retraction group than in MEE group.

PURPOSE: To investigate how the results of nasal computational fluid dynamics (CFD) simulations change due to inferior turbinate surgery and how the results correlate with patient specific subjective assessment and volumetric results in the nasal cavities. METHODS: The steady inspiratory airflow of 25 patients was studied pre- and postoperatively with heat transfer from the mucous membrane by performing CFD calculations to patient-specific nasal cone beam computed tomography images. These results were then compared to the severity of the patients' nasal obstruction Visual Analogue Scale (VAS) and Glasgow Health Status Inventory assessments, and acoustic rhinometry measurements. RESULTS: Total wall shear forces decreased statistically significantly (p < 0.01) in the operated parts of the inferior turbinates. Patients' subjective nasal obstruction VAS assessment changes between the pre- and postoperative conditions correlated statistically significantly (p = 0.04) with the wall shear force results. CONCLUSION: Inferior turbinate surgery lead to decreased total wall shear force values postoperatively. Changes in subjective nasal obstruction VAS results against total wall shear force changes between the pre- and postoperative conditions were statistically significant. CFD data have a potential to be used for the evaluation of nasal airflow.

PURPOSE: This study will evaluate the clinical quality and usability of peripheral image data from the temporal bone area obtained using a sinonasal ultra-low-dose (ULD) cone-beam computed tomography (CBCT) scan and compare them to those obtained using a high-resolution (HR) CBCT. METHODS: The population consisted of 66 anatomical sites (ears of 33 subjects) imaged using two modalities: an HR CBCT (Scanora 3Dx scanner; Soredex, Tuusula, Finland) and a ULD CBCT (Promax 3D Mid scanner; Plandent, Helsinki, Finland). The image quality (IQ) for every anatomical site in each image was rated using a Likert scale from 0 to 5. RESULTS: The quality of ULD CBCT scans was clinically sufficient in over 95% of the assessed images of the sigmoid sinus, jugular bulb, epitympanum and mastoid antrum as well as external acoustic meatus (all p > 0.05 compared to HR CBCT). The IQ was clinically sufficient in 75-94% of the assessed images of the scutum, mastoid segment of the facial nerve, cochlea and semicircular canals (all p < 0.05 compared to HR CBCT). The overall IQ of the HR CBCT scans was good or excellent. CONCLUSION: CBCT imaging and the data at image margins are underutilized. CBCT can produce excellent structural resolution with conventional imaging parameters, even with off-focus images. Using ultra-low doses of radiation, the produced IQ is clinically sufficient. We encourage ear surgeons to check the patients' imaging history and to consider the use of imaging modalities that involve lower radiation doses especially when conducting repetitive investigations and with children.

BACKGROUND/OBJECTIVES: Patients with obstructive sleep apnoea (OSA) frequently present with some form of upper airway anatomical impairment. Considerable research has been conducted on the role of the structures of the jaw and pharynx in the pathogenesis of OSA; however, the significance of the nose is somewhat unclear. Computed tomography is a widely used imaging modality for assessing the nasal cavity and paranasal sinuses, but only a small amount of the acquired data is used. Our aim was to ascertain whether the size of the cross-sectional areas of the nasal airway, measured from cone beam computed tomography (CBCT) images, is associated with OSA severity. MATERIALS/METHODS: A total of 58 patients with OSA, without any major paranasal sinus inflammatory pathology, were included in this register-based study. Patients had previously undergone ambulatory polysomnography and CBCT. The cross-sectional areas of the nasal cavity were measured in CBCT coronal sections. Statistical analyses were performed to determine any correlation between the cross-sectional area measurements and apnoea-hypopnoea index (AHI) or any significant difference in cross-sectional areas between AHI severity groups. RESULTS: No correlation was found between AHI and the smallest, total, or sum of the anterior cross-sectional areas of the nasal airway. Furthermore, there was no statistically significant difference in the cross-sectional areas between patients with the highest and lowest AHI. CONCLUSIONS/IMPLICATIONS: The small cross-sectional area of the anterior nasal cavity in patients without any major nasal pathology does not appear to be associated with OSA severity.

AIM: The difficulty of assessing the likelihood of obstructive sleep apnoea (OSA) in children who snore without full-night polysomnography is widely recognised. Our aim was to identify features that were characteristic of two-year-old children with OSA and evaluate whether this information could be used to assess the likelihood of OSA. METHODS: The study was carried out as part of the Child-Sleep Project, a longitudinal birth cohort study of children born at Tampere University Hospital, Finland. This part of the study focused on the children in the cohort who snored and was carried out between 2013 and 2015. The primary outcomes were measured using parental questionnaires, polysomnography and clinical examinations. RESULTS: In total, 52 children participated at a mean age of 27 months (range 23-34). Of these, 32 (44% male) snorers and 20 (70% male) controls. The most significant findings were that children who had OSA demonstrated longer snoring time (P = .003), a greater tendency for mouth breathing (P = .007) and bigger adenoid size (P = .008) than snorers without OSA. CONCLUSION: Snoring time, adenoid tissue size and mouth breathing were important features that identified the likelihood of OSA in snoring toddlers.

BACKGROUND: Severe uncontrolled chronic rhinosinusitis with nasal polyps (CRSwNP) is a challenging condition to treat. The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 (EPOS2020) has the following criteria when considering biological therapy for severe uncontrolled CRSwNP: eosinophilia, need for oral corticosteroids (OCS), symptom score, loss of sense of smell and co-morbid asthma. OBJECTIVE: This study aimed at finding associations of baseline factors with uncontrolled CRSwNP after endoscopic sinus surgery (ESS). METHODS: Electronic health record data of CRSwNP patients (N = 137) undergoing ESS in 2002-17 were used. Endpoints of uncontrolled CRSwNP were revision ESS, purchased OCS and antibiotic courses during follow up. Baseline factors were chosen based on EPOS2020 and the data available: nasal polyp (NP) eosinophilia, peripheral blood eosinophilia, co-existing asthma and/or non-steroidal anti-inflammatory drug exacerbated respiratory disease (NERD), need for OCS during the previous year, previous ESS, endoscopic NP score, and Lund-Mackay score of sinus computed tomography scans. RESULTS: During the follow-up of 10.1 ± 3.1 (mean ± standard deviation) years, 35 (25.5%) individuals underwent revision ESS. The best predictive model was obtained by a sum of baseline (1) blood eosinophilia ≥ 250 cells/≥l and/or NP eosinophilia ≥ 30% (Eos), (2) asthma/NERD, and (3) ≥ 1 OCS/year. It was significantly associated with revision ESS, purchased doctor-prescribed OCS and antibiotic courses during follow-up. CONCLUSIONS: We identified similar predictive variables for uncontrolled CRSwNP that are used in the EPOS2020 indications of biological therapy, thus suggesting that these estimates are usable in clinical practice.
RESUMEN
OBJECTIVES: To evaluate whether an ethmoidal drug-eluting stent (DES) (the Relieva Stratus™ MicroFlow Spacer) could better prevent endoscopic sinus surgery (ESS) than standard non-invasive therapy using corticosteroid nasal spray in patients suffering from chronic rhinosinusitis (CRS). DESIGN: Prospective, randomised clinical trial. SETTING: Tertiary referral centre. PARTICIPANTS: Sixty-three adult patients with ethmoidal involvement in cone beam computerised tomography (CBCT) whose first-line medical treatment with topical corticosteroids had failed and who were candidates for ESS were randomised either to a DES group, which received triamcinolone acetonide stents (n = 34), or to a topical intranasal corticosteroid group (n = 29) that used optimally dosed triamcinolone acetonide nasal spray. OUTCOME MEASURES: Patients were followed up prospectively for 6 months and at 36 months. Freedom from ESS was the primary endpoint. Further, we identified those factors predicting ESS. RESULTS: At 6 months, ESS could be prevented in almost half of the patients in both groups (DES 13/28, 46.4%, nasal spray 14/29, 48.3%). At 36 months, 20/28 (71.4%) patients in the DES group and 18/29 (62.1%) in the nasal spray group had been operated. The differences were not statistically significant at either timepoint. Patients who smoked (14/19, 73.7% vs 16/38, 42.1%) were more likely to be operated at 6 months. CONCLUSION: Endoscopic sinus surgery can be prevented using both therapies in the medium term in almost half of cases with neither therapy being statistically superior. This effect was somewhat diminished in the long term with a trend towards more patients being operated in the DES group. Considering the additional costs, the need for general anaesthesia and the potential side effects associated with DES, its potential clinical role appears to be limited. Smoking was significantly associated with ESS.

INTRODUCTION: The aim was to study the association between snoring and development of occlusion, maxillary dental arch, and soft tissue profile in children with newly completed deciduous dentition. METHODS: Thirty-two (18 female, 14 male) parent-reported snorers (snoring ≥3 nights/week) and 19 (14 female, 6 male) nonsnorers were recruited. Breathing preference (nose or mouth) was assessed at the mean age of 27 months by otorhinolaryngologist. At the mean age of 33 months, an orthodontic examination was performed, including sagittal relationship of second deciduous molars, overjet, overbite, and occurrence of crowding and lateral crossbite. Bite index was obtained to measure maxillary dental arch dimensions (intercanine and intermolar width, arch length). A profile photograph was obtained to measure facial convexity. RESULTS: No significant differences were found between nonsnorers and snorers in any of the studied occlusal characteristics or in measurements of maxillary dental arch dimensions. Snorers were found to have a more convex profile than nonsnorers. Occurrence of mouth breathing was more common among snorers. CONCLUSIONS: Parent-reported snoring (≥3 nights/week) does not seem to be associated with an adverse effect on the early development of deciduous dentition, but snoring children seem to have more convex profile than nonsnorers. Snoring is a mild sign of sleep-disordered breathing, and in the present study its short time lapse may not have had adequate functional impact on occlusion.

OBJECTIVES: Paediatric obstructive sleep apnoea syndrome (OSAS) is associated with a range of changes in craniofacial and occlusal development. There is, however, little knowledge of how early in life these changes can be found. The aim of the present study was to determine whether changes in dental arch morphology, occlusion, facial profile, tonsil size, breathing habit or body mass index (BMI) can already be found among 2.5-year-old children with OSAS. MATERIALS AND METHODS: Fifty-two children were recruited to the study. Of these, OSAS was diagnosed in 9 children and 18 children did not snore in polysomnography. These two groups were subsequently compared when evaluating polysomnographic, otorhinolaryngological and dental variables. RESULTS: Children with OSAS had narrower inter canine width than non-snoring children (P = 0.032). Furthermore, children with OSAS had larger adenoid size with respect to the nasopharyngeal volume (P = 0.020) and more tendency to mouth breathing (P = 0.002). No statistically significant differences were found when comparing palatine tonsil size, occlusal characteristics, soft tissue profile measurements or BMI. LIMITATIONS: The limitation of the study is the small sample size. CONCLUSION: Children with OSAS had narrower upper inter canine width than non-snoring children at the age of 2.5 years. Larger adenoid size and mouth breathing tendency were also more common among children with OSAS. Further studies with larger sample sizes are needed to determine if other changes in craniofacial and occlusal development can be found in this age group.

Acute rhinosinusitis (ARS) is a sudden, symptomatic inflammation of the nasal and paranasal mucosa. It is usually caused by respiratory virus infection, but bacteria complicate for a small number of ARS patients. The differential diagnostics between viral and bacterial pathogens is difficult and currently no rapid methodology exists, so antibiotics are overprescribed. The electronic nose (eNose) has shown the ability to detect diseases from gas mixtures. Differential mobility spectrometry (DMS) is a next-generation device that can separate ions based on their different mobility in high and low electric fields. Five common rhinosinusitis bacteria (Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, Staphylococcus aureus, and Pseudomonas aeruginosa) were analysed in vitro with DMS. Classification was done using linear discriminant analysis (LDA) and k-nearest neighbour (KNN). The results were validated using leave-one-out cross-validation and separate train and test sets. With the latter, 77% of the bacteria were classified correctly with LDA. The comparative figure with KNN was 79%. In one train-test set, P. aeruginosa was excluded and the four most common ARS bacteria were analysed with LDA and KNN; the correct classification rate was 83 and 85%, respectively. DMS has shown its potential in detecting rhinosinusitis bacteria in vitro. The applicability of DMS needs to be studied with rhinosinusitis patients.

According to studies based on bacterial cultures of middle ear fluids, Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis have been the most common pathogens in acute otitis media. However, bacterial culture can be affected by reduced viability or suboptimal growth of bacteria. PCR detects bacterial DNA from samples with greater sensitivity than culture. In the present study, we analyzed the middle ear pathogens with both conventional culture and semiquantitative real-time PCR in 90 middle ear fluid samples obtained from children aged 5 to 42 months during acute otitis media episodes. Samples were tested for the presence of S. pneumoniae, H. influenzae, M. catarrhalis, Alloiococcus otitidis, Staphylococcus aureus, and Pseudomonas aeruginosa One or more bacterial pathogens were detected in 42 (47%) samples with culture and in 69 (77%) samples with PCR. According to PCR analysis, M. catarrhalis results were positive in 42 (47%) samples, H. influenzae in 30 (33%), S. pneumoniae in 27 (30%), A. otitidis in 6 (6.7%), S. aureus in 5 (5.6%), and P. aeruginosa in 1 (1.1%). Multibacterial etiology was seen in 34 (38%) samples, and M. catarrhalis was detected in most (85%) of those cases. Fifteen signals for M. catarrhalis were strong, suggesting a highly probable etiological role of the pathogen. In conclusion, even though M. catarrhalis is often a part of mixed flora in acute otitis media, a considerable proportion of cases may be primarily attributable to this pathogen.

Tongue cancer has a poor prognosis due to its early metastasis via lymphatic vessels. The present study aimed at evaluating lymphatic vessel density, relative density of lymphatic vessel, and diameter of lymphatic vessels and its predictive role in tongue cancer. Paraffin-embedded tongue and lymph node specimens (n = 113) were stained immunohistochemically with a polyclonal antibody von Willebrand factor, recognizing blood and lymphatic endothelium and with a monoclonal antibody podoplanin, recognizing lymphatic endothelium. The relative density of lymphatic vessels was counted by dividing the mean number of lymphatic vessels per microscopic field (podoplanin) by the mean number of all vessels (vWf) per microscopic field. The high relative density of lymphatic vessels (≥80 %) was associated with poor prognosis in tongue cancer. The relative density of lymphatic vessels predicted poor prognosis in the group of primary tumor size T1-T2 and in the group of non-metastatic cancer. The lymphatic vessel density and diameter of lymphatic vessels were not associated with tongue cancer survival. The relative density of lymphatic vessels might have clinically relevant prognostic impact. Further studies with increased number of patients are needed.

Anatomical complexity presents the main challenge in the administration of topical corticosteroid therapy to the paranasal sinus mucosa. This often leads to suboptimal drug delivery due to low concentrations of the therapeutic agent to the intended target area. The Relieva Stratus™ MicroFlow Spacer (Relieva Stratus) is a drug-eluting stent that is temporarily implanted into the ethmoid sinus. The reservoir of the stent is filled with triamcinolone acetonide, which is then slowly released from the device into the ethmoid sinus mucosa. The Relieva Stratus provides local and targeted delivery of the anti-inflammatory agent to the diseased mucosa. This minimally invasive implant is an option when treating ethmoid sinusitis. From January 2011 to November 2013, a total of 52 Relieva Stratus implantations into the ethmoidal cells were performed at the Department of Ear and Oral Diseases at Tampere University Hospital, Finland. C-arm fluoroscopy guidance was employed for 26 sinuses (13 patients) and optical image-guided surgery (IGS)-assisted insertions were performed on another 26 sinuses (13 patients). The accuracy of fluoroscopic insertion is not optimal, but this method is accurate enough to prevent the violation of the skull base and lamina papyracea. IGS enables the precise treatment of the diseased cells. From a technical perspective, IGS-guided insertion is a faster, safer and more exact procedure that guarantees the optimal positioning and efficacy of the implant. Moreover, IGS guidance does not entail the use of ionizing radiation.

Botulinum toxin A (BTX-A) injections to the salivary glands are effective in the treatment of drooling, and complications are rare. However, there are only a few previous reports on the long-term use of BTX-A injections. This study retrospectively analyzes our experience of treating drooling with repeated BTX-A injections in patients with neurodegenerative diseases. All patients who received repeated BTX-A injections to the submandibular glands at Tampere University Hospital in 2004-2013 were included in the analysis. Six patients, aged from 6 to 21 years, were included in the study, and a total of 41 bilateral BTX-A injections were administered to their submandibular glands. The average number of injections per patient was 6 (range: 3-11). The average interval between the injections was 9.8 months (range: 4-18), and 95% (39/41) of the injections were performed with good response. The complication rate of the BTX-A injections was 2.4% (1/41), since one of the patients had swallowing problems after an injection. BTX-A injections to the submandibular glands are effective and have a low morbidity rate, and repeated injections can be recommended as long-term treatment of drooling.

AIMS: To evaluate the effect of a cochlear implant (CI) on quality of life (QoL), quality of hearing (QoH), and working performance in patients with single-sided deafness (SSD). METHODS: Using specific questionnaires, we measured QoL, QoH, and working performance in 7 SSD patients scheduled for CI surgery of the affected ear. Sound localization and speech perception in noise were also assessed. All questionnaires and tests were performed before the CI surgery and at 6 and 12 months after CI activation. RESULTS: The QoL, QoH, sound localization, and speech perception in noise had improved statistically significantly after CI surgery. Communication with co-workers became easier, and the patients were less fatigued after the working day. CONCLUSIONS: CI clearly improves QoL, QoH, and working performance in patients with SSD.

Sialendoscopy is used in the diagnosis and treatment of various symptoms relating to the salivary gland, e.g. chronic swelling or obstruction and inflammation of the salivary duct. Small intraductal stones can be removed with various instruments during sialendoscopy, whereas larger ones can be fragmented with extracorporeal shockwave lithotripsy or laser. However, 5-10% of the patients with parotid stones cannot be treated with these methods. In patients with large impacted stones or stones in a hilus area, a combined endoscopic and transcutaneous technique can be employed. The stone is approached endoscopically, a skin flap is raised over or a small incision is made through the illuminated area, and the stone is removed by an external route with minimal morbidity. This retrospective study analysed the cases of 8 patients treated using the combined technique, 6 of whom became symptom free. Superficial parotidectomy was performed in 1 patient. No complications were observed, and ductal stents were not used. The average diameter of the stones was 7.6 mm (range 7.0-10.2). The combined technique is recommended for the removal of large and impacted intraductal stones in the parotid gland. No major complications have been reported.

Acute epiglottitis in children has almost vanished since the start of Hib vaccinations. Supraglottitis often develops in adults more slowly than in children. We reviewed all patients at Tampere University Hospital over the age of 18, who had been recorded with a diagnosis of epiglottitis or supraglottitis upon discharge from the hospital between 1989 and 2009. The most common symptoms were sore throat and pain on swallowing. Streptococcus was the most common causative agent. Most of the 308 patients had received conservative treatment. Supraglottitis should be remembered as possible diagnosis when an adult person complains of a sore throat.

OBJECTIVE: Detecting bacteria as a causative pathogen of acute rhinosinusitis (ARS) is a challenging task. Electronic nose technology is a novel method for detecting volatile organic compounds (VOCs) that has also been studied in association with the detection of several diseases. The aim of this pilot study was to analyze maxillary sinus secretion with differential mobility spectrometry (DMS) and to determine whether the secretion demonstrates a different VOC profile when bacteria are present. METHODS: Adult patients with ARS symptoms were examined. Maxillary sinus contents were aspirated for bacterial culture and DMS analysis. k-Nearest neighbor and linear discriminant analysis were used to classify samples as positive or negative, using bacterial cultures as a reference. RESULTS: A total of 26 samples from 15 patients were obtained. After leave-one-out cross-validation, k-nearest neighbor produced accuracy of 85%, sensitivity of 67%, specificity of 94%, positive predictive value of 86%, and negative predictive value of 84%. CONCLUSIONS: The results of this pilot study suggest that bacterial positive and bacterial negative sinus secretion release different VOCs and that DMS has the potential to detect them. However, as the results are based on limited data, further conclusions cannot be made. DMS is a novel method in disease diagnostics and future studies should examine whether the method can detect bacterial ARS by analyzing exhaled air.

Pott's puffy tumor is an extremely rare complication of frontal sinusitis. It is most typically found in young men. Streptococci, staphylococci or anaerobic bacteria are usually the causative agents. In our patients the inflammation was caused by Streptococcus milleri and Streptococcus pneumoniae. The treatment should be started with broad-spectrum antibiotics. The antibiotics are administered intravenously for 1 to 2 weeks and thereafter orally for at least four weeks. Paranasal sinuses must be operated, and if necessary, intracranial abscesses are treated neurosurgically.

Nocardia is regarded as an opportunistic pathogen primarily affecting the respiratory system, whereas Nocardia farcinica is the species of the Nocardia family that is most frequently blamed for central nervous system impairment. The authors present the first case of mastoiditis caused by Nocardia farcinica, accompanied by intracranial complications. An immunocompetent 74-year-old woman who reported a three-week left ear discharge and a two-week facial nerve palsy was referred to our department. MRI revealed mastoiditis and epidural abscess. The bacterial cultures obtained during the surgical management of the patient confirmed the presence of Nocardia farcinica. Targeted antibiotic therapy was subsequently administrated, gradually resulting in favourable outcomes. Nocardia species provoke a disseminated infection that emerges not only among the immunosuppressed individuals but can also affect the healthy population. The nonspecific clinical manifestations in addition to the difficulties identifying the pathogen, remain obstacles to a punctual diagnosis. However, the combination of surgical debridement and antibiotic treatment with trimethoprim and sulfamethoxazole is considered the most appropriate management, leading to propitious results.
