UNILATERAL VS. DIFFUSE CHRONIC RHINOSINUSITIS.

Chronic rhinosinusitis (CRS) is a widespread disease with various symptoms. It is defined as an inflammation of the nasal mucosa and paranasal sinuses lasting for 12 weeks, with symptoms of nasal obstruction and/or congestion and facial pain and/or pressure as well as decreased sense of smell. Despite the widespread prevalence of the disease, the diagnosis and treatment of CRS are still not adequately developed, so many patients remain misdiagnosed. This study involved 150 patients who, according to EPOS guidelines, met the diagnosis of CRS without nasal polyposis. Each patient underwent a computerized tomography (CT) scan of the paranasal sinuses, which was evaluated according to the Lund-Mackay scoring system. Furthermore, patients completed a visual analog scale (VAS) score questionnaire which examined the severity of their symptoms. The aim of this study was to find an association between the degree of mucositis and the clinical symptoms reported by the patient. Our results showed a low positive correlation between nasal secretion and Lund-Mackay score for the bilateral ostiomeatal complex (OMC). Furthermore, a low positive correlation was found between the severity of reduced sense of smell and severity of anterior ethmoid and sphenoid sinusitis. The results demonstrated a low negative correlation between the severity of facial pain or pressure and the severity of inflammation of the anterior ethmoid and sphenoid sinus. The results of statistical testing did not show statistical differences in severity of subjective symptoms for almost all of the observed symptoms in persons with unilateral inflammation and persons without unilateral inflammation, except for cough. People who did not have unilateral inflammation had a more pronounced cough compared with people who had unilateral inflammation. However, these correlations were very mild and not clinically significant, so we cannot say that the distribution of sinusitis significantly affects the occurrence of characteristic symptoms in chronic rhinosinusitis.

Imaging in chronic rhinosinusitis: A systematic review of MRI and CT diagnostic accuracy and reliability in severity staging.

BACKGROUND: Computerized tomography (CT) severity scores are frequently used as an objective staging tool in chronic rhinosinusitis (CRS). Magnetic resonance imaging (MRI) has also been proposed as a valid option in CRS imaging. PURPOSE: The aim of this systematic review was to briefly present the recent developments on sinus imaging utilized in clinical practice with regard to diagnostic accuracy of imaging and severity staging in CRS according to evidence-based medicine (EBM) principles. MATERIAL AND METHODS: This review paper has been assembled following PRISMA guidelines. A PubMed and Scopus (EMBASE) search using CRS, "severity staging", "diagnostic accuracy "and "imaging "resulted with 80 results. Of these, only 12 (59%) contained original data, constituting the synthesis of best-quality available evidence. RESULTS: CT is the most commonly used imaging technique for the severity staging of CRS, but a question of higher cumulative radiation dose should be taken into consideration when repeating CT examinations in evaluating treatment efficacy. MRI may be a complementary diagnostic and staging tool, especially when repeated examinations are required, or when paediatric CRS patients are evaluated. The severity staging system may be improved to better correlate with subjective scores. CONCLUSIONS: MRI may be utilized as a staging tool with comparable diagnostic accuracy, using the same staging systems as with CT examinations.

Differences in self-reported symptoms in patients with chronic odontogenic and non-odontogenic rhinosinusitis.

PURPOSE: To evaluate the possible differences in self-reported symptoms between patients with chronic odontogenic rhinosinusitis (CORS) and patients with chronic non-odontogenic rhinosinusitis (CnORS). MATERIALS AND METHODS: The study included 64 patients diagnosed with chronic rhinosinusitis according to EPOS guidelines. 32 patients had CORS, and the control group were 32 patients with CnORS. Patients were matched according to gender and age. All the patients underwent a CT scan evaluated by a radiologist, and were evaluated by an oral surgeon and otorhinolaryngologist before being assigned to one of the groups. The severity of the symptoms was assessed through questioners SNOT-22 (sino-nasal outcome test) and VAS (visual analogue scale) symptom score. Kolmogorov-Smirnov's, Fisher's and Mann-Whitney U test were used in the statistical analysis of the data. RESULTS: People with CORS show similar symptomatology on SNOT-22 score to patients with CnORS, with no significant statistical difference between any of the SNOT-22 symptoms. VAS symptom score showed that odontogenic group had a significantly higher score for fever (p = .004) and halitosis (p = .003). CONCLUSION: Halitosis and fever might be the most important symptoms in differentiating between CORS and CnORS symptomatology. Better diagnostic tools, such as VAS symptom score might help medical professionals to be quicker at recognizing CORS specific symptomatology, and help them treat the disease as early and adequately as possible.

Cluster Analysis of Chronic Rhinosinusitis Suggests Gender-Based Differences.

PURPOSE: We aimed to evaluate the interaction between the overall severity of chronic rhinosinusitis (CRS) before treatment and subjective improvement following surgical or medical treatment. PROCEDURES: A group of 97 patients with CRS completed the visual analog scale (VAS) symptom score and the Sino-Nasal Outcome Test 22 (SNOT-22) questionnaire in the moment of their sinus computerized tomography (CT) scan. Data were analyzed via a 2-step cluster analysis based on gender, polyp presence, CT scan, and VAS scores for symptoms. RESULTS: There were 3 clusters: the first cluster comprised 37 female patients with CRS without nasal polyps (CRSsNP), the second cluster comprised 30 patients with CRS and NP (CRSwNP; 15 males and 15 females); and third cluster had 30 male patients with CRS without NP (CRSsNP). Different symptom patterns between clusters were identified. After adjustment for polyp presence, gender, eosinophilia (p = 0.021), and the SNOT-22 score (p = 0.005) were found to be better outcome predictors than the CT score (p = 0.26). CONCLUSION: Long-term patient satisfaction is significantly associated with the subjective symptom severity prior to treatment, i.e., postnasal drip and overall disease severity (SNOT-22 score), but not with the objective severity of the disease (CT score and inflammation).

Association between computed tomography findings and clinical symptoms in chronic rhinosinusitis with and without nasal polyps.

Objective of this study was to test whether there is a difference between chronic rhinosinusitis patients with (CRSwNP) and without (CRSsNP) nasal polyps in the association of extent of disease on CT scans with symptom severity and health-related quality-of-life (HRQL) impairment. Data sets from 271 chronic rhinosinusitis (CRS) patients who completed the Sino-Nasal Outcome Test 22 (SNOT-22) and visual analog scale (VAS) scores were subjected to principal component analysis (PCA) to identify a symptom components related to CRS. After controlling for demographics, medical therapy, and comorbidities, the association between symptom components/items excluded from PCA and Lund-Mackay score (LMS) was evaluated. No association was found between the total SNOT-22 score and LMS in CRS patients. There was an independent association between a higher "nasal" symptom component derived from SNOT-22 PCA and LMS in patients with CRSwNP (p < 0.001), but not in CRSsNP patients, with a statistically significant difference between two patient subsets (p = 0.003). In patients with CRSsNP, higher (worse) SNOT-22 "facial pain" was associated with lower LMS (p = 0.022), although the estimated change in LMS was modest. Considering VAS PCA components, higher "nasal" symptoms were associated with higher LMS in CRSwNP patients (p < 0.001) but not in CRSsNP, with a statistically significant difference between CRS groups (p = 0.024). A higher "pain" PCA component was associated with lower LMS in CRSsNP patients (p = 0.019). This study found significant differences in the relationship between symptom burden and CT scores between CRS phenotypes and no association between HRQL impairment and CT scores.

Relationship between nasal septal deformity, symptoms and disease severity in chronic rhinosinusitis.

The objective of this study was to evaluate the interaction of nasal septal deformity (NSD), including the contribution of septal spurs, with the severity of subjective symptoms, impairment of health-related quality of life (HRQoL) and sinus mucosal hyperplasia in patients with chronic rhinosinusitis (CRS). One hundred seventeen patients with CRS were assigned to three groups with mild, moderate or severe NSD, according to the measured nasal septal angle, including the presence of contact septal spurs. All CRS patients completed the visual analog scale (VAS) symptom severity score and the Sino-Nasal Outcome Test (SNOT-22) questionnaire. Symptoms scores, SNOT-22 and Lund-Mackay (LM) scores among the three NSD groups were compared. Related anatomy from the study group was compared with 100 control patients. VAS score for postnasal discharge in CRS patients was significantly higher in patients with mild NSD. There was a significantly higher LM score in CRS patients with severe NSD, compared to those with mild (P = 0.001) or moderate NSD (P = 0.005). CRS patients with a contact spur demonstrated a significantly higher LM score (P = 0.006) compared to those without a contact spur, and no differences in VAS symptom scores or HRQoL scores. There was a similar prevalence of septal deformities in CRS patients and in the non-ENT population. Our results support the conclusion that in patients with CRS, associated NSD or contact septal spur do not contribute significantly to CRS symptom severity or HRQoL impairment, but may have an impact on sinus mucosal hyperplasia.

Hypercalcemia Associated With Severe Dysphagia in a Patient With Parathyroid Adenoma and Significant Cervical Spondylophytes.

Background/Objective: Severe dysphagia is a rare presenting symptom of primary hyperparathyroidism, whereas the most common hypercalcemia-related causes include gastrointestinal symptoms, such as anorexia, constipation, and pancreatitis. This case presentation aimed to describe swallowing difficulty as a leading symptom of hypercalcemia. Case Report: A 62-year-old man experienced vomiting, dysphagia bordering with aphagia, and 20-kg weight loss in a 2-month period. The parathyroid hormone and serum calcium levels were 102 pmol/L (reference range, 1.8-7.9 pmol/L) and 4.12 mmol/L (reference range, 2.14-2.53 mmol/L), respectively. Ultrasound-guided exploration of the neck revealed a large, rounded hypoechoic mass inferior to the left thyroid lobe, which contained parathyroid tissue on fine-needle aspiration cytology examination. Contrast-enhanced neck computed tomography revealed a mass measuring 3.6 × 2.6 × 2.5 cm behind the left thyroid lobe, alongside massive ventral spondylophytes of the cervical spine at the level of the postcricoid segment of the hypopharynx. Magnetic resonance imaging confirmed ventral tissue displacement due to spondylophyte size and location. Surgical exploration of the left side of the neck was performed, and the left lower parathyroid gland weighing 9.07 g was excised. Pathohistologic findings verified a parathyroid gland adenoma. The postoperative values showed parathyroid hormone and serum calcium levels at 4.54 pmol/L and 2.25 mmol/L, respectively. Discussion: The pathophysiology of dysphagia in hypercalcemia is not fully elucidated. In this case, the patient's improvement after surgery implies a plausible connection between hypercalcemia and dysphagia, suggesting a causal relationship. Conclusion: Although aphagia is not a typical presenting symptom of parathyroid adenoma, it should be noted in the differential diagnosis.

Diagnostic Accuracy of Preoperative CT and Endoscopy Staging in Early Laryngeal Cancer.

OBJECTIVES: This study aims to evaluate the diagnostic accuracy of preoperative computed tomography (CT) and intraoperative endoscopic tumor staging with regard to histopathologic staging in patients with early laryngeal cancer. STUDY DESIGN: A retrospective nonrandomized single-institution comparative cohort study including 109 patients. SETTING: A tertiary surgical center. METHODS: Patients were treated for T1a, T1b, and T2a laryngeal squamous cell carcinoma by endoscopic laser surgery. The outcome measures were the presence of under- or overstaging in endoscopic and CT findings and positive postoperative margins. RESULTS: Endoscopic overstaging as compared with histopathologic T category correlated with rising tumor category (P = .001; odds ratio [OR], 69.1) and CT findings showing anterior commissure involvement (P = .002; OR, 9.54), while endoscopic understaging correlated with rising tumor histologic grade (P = .039; OR, 4.28) and smaller tumor size (P = .011; OR, 6.39). CT overstaging vs histopathologic T category correlated with CT findings showing anterior commissure involvement (P = .001; OR, 21.76), supraglottic involvement (P = .001; OR, 59.98), subglottic involvement (P = .001; OR, 39.94), rising clinical T category (P = .01; OR, 9.11), and rising tumor histologic grade (P = .004; OR, 10.95). CT understaging as compared with histopathologic T category correlated with smaller clinical T categories (P = .002; OR, 12.72) and smaller tumor histologic grade (P = .030; OR, 7.02). Rising age, rising tumor size, anterior commissure involvement on CT, and tumor extension into the supraglottis were risk factors for positive margins. CONCLUSION: Our results indicate that CT adds little valuable information in differentiating small superficial lesions in the glottis, while systematically overstaging cases of early laryngeal cancer. In T1a and T1b glottic tumors, endoscopy should be the preferred diagnostic method.

A systematic review of common landmarks in navigated endoscopic sinus surgery (NESS).

BACKGROUND: Navigation brought about a tremendous improvement in functional endoscopic sinus surgery (FESS). When upgraded accordingly, FESS becomes navigated endoscopic sinus surgery (NESS). Indications for intraoperative use of navigation can be broadened to almost any FESS case. NESS in advanced sinus surgery is currently still not used routinely and requires systematic practice guidelines. PURPOSE: The purpose of this paper is to report on commonly identified landmarks while performing advanced NESS according to evidence-based medicine (EBM) principles. MATERIAL AND METHODS: This review paper has been assembled following PRISMA guidelines. A PubMed and Scopus (EMBASE) search on anatomical landmarks in functional endoscopic and navigated sinus surgery resulted in 47 results. Of these, only 14 (29.8%) contained original data, constituting the synthesis of best-quality available evidence. RESULTS: Anatomical landmarks are considered to be the most important points of orientation for optimal use of navigation systems during FESS surgery. The most commonly identified significant landmarks are as follows: (1) Maxillary sinus ostium; (2) Orbital wall; (3) Frontal recess; (4) Skull base; (5) Ground lamella; (6) Fovea posterior; (7) Sphenoid sinus ostium. Conclusions: Establishing common landmarks are essential in performing NESS. This is true for advanced and novice surgeons alike and offers a possibility to use navigation systems systematically, taking advantage of all the benefits of endoscopic navigated surgery.

The impact of asthma on quality of life and symptoms in patients with chronic rhinosinusitis.

Objective: The study aims to evaluate how asthma influences on clinical symptoms, imaging scores and HRQL in CRS patients.Methods: The study enrolled CRS patients and collected data about asthma status, clinical symptoms, allergic sensitization, computed tomography (CT) and 22-item SinoNasal Outcome questionnaire (SNOT-22). Matching pairs of asthmatic and non-asthmatic CRS patients were defined based on age, gender and nasal polyp presence. The difference between pairs in clinical symptoms, CT and SNOT-22 was then analyzed. The study enrolled mild to moderate asthma patients.Results: From 250 CRS patients 65 (26%) had asthma. We found 60 CRS asthma and CRS non-asthma pairs based on age, gender and nasal polyp presence. There was no difference in total SNOT-22 score between asthma (46.5) and non-asthma (43.5) CRS groups (p < .357). There were more patients with allergy positive medical history in asthma group (66.1%) when we stratified for CRS phenotypes, gender and age. Comparing visual analogue scale (VAS) scores for clinical symptoms, smell (p < .013) was the only symptom significantly worse in CRS asthma group. Although there was no difference in Lund-Mackay score, there was a slightly higher osteitis score in CRS asthma group (5.21 vs. 3.45; p = .059).Conclusion: CRS patients with asthma have significantly worse impairment of smell and taste when compared to non-asthmatic CRS patients. This is the only significant difference which is independent of nasal polyp presence, gender, age and allergy.

An internal carotid artery pseudoaneurysm with neck hematoma: A rare cause of a life-threatening neck mass mimicking an abscess.

A neck mass has a broad and complex differential diagnosis, generally divided into neoplastic, congenital and inflammatory categories. An internal carotid artery hemorrhage with pseudoaneurysm formation is a very rare entity that may resemble other common conditions in the differential diagnosis. Large, expanding or symptomatic pseudoaneurysm is critical to efficiently diagnose and manage, due to risk of life-threatening hemorrhage. We present a case of an adult male patient with clinical and laboratory signs of severe neck cellulitis and a large gradually increasing neck mass, primarily suggestive of an abscess. Neck CT and MRI imaging revealed the presence of a disruption of the internal carotid artery resulting in a large hematoma and formation of pseudoaneurysm. A multidisciplinary team of interventional radiologists and ENT surgeons successfully treated the patient by endovascular placement of stents and subsequent surgical drainage. Awareness of such a rare, life-threatening condition and efficient multidisciplinary teamwork are essential for patient management.

Recovery From Sudden Sensorineural Hearing Loss May Be Linked to Chronic Stress Levels and Steroid Treatment Resistance.

Purpose This article investigates the possible connections between the level of chronic stress and success of steroid therapy in patients with sudden sensorineural hearing loss (SSNHL). Method A single-center, retrospective, longitudinal cohort study on 55 patients in a tertiary referral otology center was examined. Patients diagnosed with SSNHL between 2014 and 2017 were asked to complete a Measure of Perceived Stress (Brajac, Tkalcic, Dragojevic, & Gruber, 2003 ) questionnaire. Inclusion criteria were patients > 18 years of age, SSNHL diagnosed within 4 previous weeks, completed steroid treatment, and complete documentation. Results There were 30 patients (55%) that showed significant improvement in their pure-tone audiogram (PTA) hearing threshold average (≥ 15 dB) after steroid treatment. Two-step cluster analysis identified 3 clusters based on average PTA hearing threshold recovery and average Measure of Perceived Stress scores. The difference between pretreatment and posttreatment hearing levels was significantly higher in the cluster with moderate stress compared to clusters with mild and high stress levels (Kruskal-Wallis test, Friedman test, p < .001). There were no significant differences in average PTA hearing threshold recovery after steroid therapy between groups of patients with mild and severe stress. Conclusion Patients with moderate stress levels show significantly better results after steroid treatment for SSNHL than patients with low or high stress levels.

Tolosa-Hunt Syndrome - Case Report.

This case report presents a patient diagnosed with Tolosa-Hunt syndrome (THS) after an extensive neuro-diagnostic and neuroimaging evaluation. Diagnostic work-up included thorough physical and neurological examination, complete laboratory serum assessments, neuroendocrine and immunohistochemistry analysis, cerebrospinal fluid analysis, neurophysiology assessment, ophthalmologist examination and neuroimaging. Th e most important diagnostic tool in deriving the diagnosis of THS was neuroimaging evaluation that included baseline and follow-up cranial contrast enhanced magnetic resonance imaging (MRI). Baseline cranial contrast enhanced MRI detected a nonspecific inflammatory granulomatous lesion in the right cavernous sinus extending basally towards the right trigeminal cave (Meckel's cave) and anteriorly towards the apex of the right orbit. Systemic intravenous high-dose corticosteroid therapy was administered for 3 consecutive days and then tapered down to lower oral steroid doses. Following therapy, the patient experienced complete regression of symptoms. Follow-up cranial contrast enhanced MRI showed significant regression of inflammatory lesion in the area of right cavernous sinus, thus verifying the efficacy of the treatment applied. This paper shows that an extensive diagnostic schedule for THS must be conducted prior to therapeutic treatment, for the possibility of alternative diagnosis. Patients suspected of having THS require careful evaluation, appropriate treatment, and follow-up.

Evaluation of the Head Multislice Computed Tomography Scan in Emergency Department.

The aim of the study was to examine the prevalence of head injuries, acute stroke and brain tumors obtained from computed tomography (CT) scans in the emergency department (ED) during a one-year period. We also assessed the potential effect of seasons on the occurrence of stroke, head trauma and tumors found on CT scans, expressed in monthly intervals. This retrospective review included all patients that underwent emergency head CT from the hospital database. A total of 3888 head CT examinations were performed in adult patients presenting to ED and 1424 CT scans had at least one pathologic finding meeting diagnostic criteria for the study. Of the total number of CT scans analyzed, acute stroke was identified in 552 (14.19%), head trauma in 660 (16.97%), and brain tumor in 212 (5.45%) patients. Head trauma was more commonly found in males (n=465, 70.45%) than in females (n=195, 29.54%). Acute stroke was slightly more common in males than in females. Brain tumors were more frequently found in female patients. There were monthly variations in the number of head injuries and acute stroke diagnosed during the study period. Men and elderly patients were found to account for the greatest number of traumatic head injuries and therefore are at the highest risk of possible brain injury.

Differences in the Sino-Nasal Outcome Test 22 and visual analog scale symptom scores in chronic rhinosinusitis with and without nasal polyps.

BACKGROUND: Chronic rhinosinusitis (CRS) with and without polyps has a high impact on health-related quality of life (HRQL), but the difference in HRQL and symptom presentation between two clinical phenotypes of CRS has not been specifically evaluated before now. OBJECTIVE: To evaluate patterns of symptoms and HRQL disease-specific domains affected in patients with CRS by comparing differences between two clinical phenotypes, adjusted for demographics, major risk factors, comorbidities, current medical treatment, and previous surgery. METHODS: A group of 251 patients with CRS completed the visual analog scale (VAS) symptom severity score and the Sino-Nasal Outcome Test 22 (SNOT-22) questionnaire. Data sets were analyzed by using principal component analysis (PCA) to identify a set of symptom components, together with the items excluded from PCA, which were then analyzed for differences between patients with CRS with nasal polyps (CRSwNP) and patients with CRS without nasal polyps (CRSsNP). RESULTS: PCA of SNOT-22 items identified six components, three referred to CRS-specific symptoms termed "nasal"; "extranasal, rhinologic"; and "olfactory/cough"; and three referred to HRQL impairment termed "sleep disturbance," "functional disturbance," and "emotional disturbance." Nasal obstruction, ear pain, ear fullness, and fatigue were excluded from PCA and treated as separate outcomes. Patients with CRSwNP had significantly worse nasal symptoms, olfactory/cough symptoms, and nasal obstruction. Patients with CRSsNP scored significantly worse with regard to fatigue and to sleep and functional disturbances. The PCA results for VAS scores identified three symptom components: pain, nasal symptoms, and pharyngeal symptoms. Patients with CRSwNP had significantly worse VAS nasal symptoms but less pronounced VAS pain symptoms than patients with CRSsNP. The total SNOT-22 score between the groups was not significantly different. CONCLUSION: With controlling of covariates that may influence the severity of the disease, this study showed significant differences in symptom patterns and different aspects of HRQL impairment between patients with CRSwNP and patients with CRSsNP, however, with no difference in the total HRQL score.
