Value of Hounsfield Units in the Evaluation of Isolated Sphenoid Sinus Lesions.

Radiologic findings of fungal sinus disease are generally opacification in paranasal computed tomography (CT) images. The Hounsfield unit (HU) is a standardized objective unit that is also suitable for measuring remodeling and opacifications on CT scans of bone sections of patients with chronic rhinosinusitis. We hypothesized that HU values could provide valuable information in isolated sphenoid sinus lesions before surgery. Between 2012 and 2019, 35 patients underwent functional endoscopic sinus surgery for sphenoid sinus lesions. Tissues obtained from the sphenoid sinus were divided into two groups, fungal and nonfungal, according to the findings of histopathologic examinations. HU values were measured in sphenoid sinus sections on paranasal CT scans of these two groups. Differences in mean and maximum HU values between the two groups were statistically significant (p < .05). The maximum HU values calculated from the sphenoid sinus were 435.08 and 196.23 (p ≤ .05) in the fungal group and nonfungal group, respectively. The mean HU values calculated from the sphenoid sinus were 64.31 and 29 (p ≤ .05) in the fungal and nonfungal groups, respectively. At the maximum cutoff value of 241, the sensitivity and specificity of the HU maximum were 84.6% and 77.3%, respectively. At the mean cutoff value of 41.5, the sensitivity and specificity of the HU mean were 76.9% and 86.4%, respectively. HU is an objective value used in radiographic density measurement. The HU values were higher in fungal lesions than in nonfungal inflammations, and they are useful in preoperative measurement.

Anterior Skull Base Surgery via Endoscopic Endonasal Approach: Outcomes and Analysis.

BACKGROUND: This study was retrospectively conducted to evaluate the postoperative surgical results of our patients with anterior skull base mass, defect, and/or cerebrospinal fluid rhinorrhea who underwent reconstruction via endoscopic endonasal approach and to share our experiences. METHODS: Sociodemographic features of patients who had undergone endoscopic surgery in our clinic due to anterior skull base mass, defect, or rhinorrhea were evaluated in terms of etiological factors, surgical method, pathology, postoperative complications, need for revision surgery and comorbid disease. RESULTS: A total of 131 patients were included; 76 were male and mean age was 36.2 years. Endoscopic endonasal surgery was performed for nasal mass (70.2%) in 92 cases, rhinorrhea (17.6%) in 23 cases, chronic sinusitis (7.6%) in 10 cases, and gunshot injury (4.6%) in 6 cases. After surgery, benign mass pathology was detected in 75 patients and malignant mass pathology was detected in 23 patients. Osteoma was the most common among benign formations, and squamous cell carcinoma was the most common among malignant formations. The most common cause of surgical revision was nasal masses (25 cases, 77.4%). CONCLUSION: Endoscopic intracranial interventions and increased anterior skull base surgery are garnering increased interest of physicians as endoscopic approaches are gaining popularity in recent years. Successful results are achieved through appropriate diagnostic methods and endoscopic approaches. Success rates will be further increased due to developing technology and imaging methods, while the risk of complications and revision surgery will be further reduced.

Giant ethmoidal mucocele leading to proptosis and hypertelorism in a pediatric patient with cystic fibrosis: a case report.

BACKGROUND: Chronic sinusitis and its complications are common in patients with cystic fibrosis. Mucoceles are one of these complications and can have life-threatening consequences if left untreated. CASE: We present the case of a giant ethmoid mucocele leading to proptosis and hypertelorism in a 5-year-old child with cystic fibrosis. CONCLUSION: Chronic sinusitis and its complications are common in patients with CF. Mucoceles are a rare complication of sinusitis that can be treated surgically. As seen in this case if left untreated mucoceles can lead to orbital pathologies such as proptosis, hypertelorism. To the best of our knowledge, we report the first case report of giant ethmoidal mucocele leading to proptosis and hypertelorism in a patient with cystic fibrosis.

Maxillofacial Trauma in Geriatric Population.

BACKGROUND/AIM: The worldwide population is increasingly aging. Maxillofacial fractures of the geriatric population have been increased. Evaluation of the demographic variables, causes and the patterns of maxillofacial traumas in the elderly population is the main aim of this study. MATERIALS AND METHODS: Seven hundred thirteen maxillofacial tomography images which were scanned between 2010 and 2019 were evaluated. Data from 50 patients aged 65 years old and/or older, who were treated for maxillofacial fracture at the Department of Otorhinolaryngology, Gaziantep University, were retrospectively analyzed. Two groups were created according to the facial fracture pattern. Facial fractures were reclassified into 2 groups; mandibula, orbital, zygomaticomaxillary complex group fractures and the other group of frontal, naso-orbito-ethmoid fractures and were used as a comparison. RESULTS: The mean age of the patients was 72.5 (min 65- max 93). The gender distribution was 17 females (34%) and 33 males (66%). The most common fractured bone was the nasal bone and the least one is the frontal bone. Approximately one-quarter of 50 fractures were seen in 70 to 79 years old. Falling is more common in females and men are more prone to work-related accidents than home-related accidents. CONCLUSION: Facial fractures in the elderly often seen in midface location. Falling is the common etiology of facial fracture in all genders at elderly. However, male dominance is seen in other etiological factors. Additional diseases in the elderly seem to increase the severity of facial fracture.

Change in Warthin's tumor incidence: a 20-year joinpoint trend analysis.

PURPOSE: The incidence of Warthin's tumor (WT) has increased worldwide. In this study, we aimed to evaluate the incidence of WT in our hospital, which provides health care for an extremely large population. METHODS: We retrospectively evaluated 573 patients, comprising 345 males and 228 females, who all experienced parotid tumor for the past 20 years. Patients with WT that were operated in the last 20 years were evaluated according to the number of patients per year to determine the annual WT increase trend. RESULTS: In the distribution of WT over the years of surgery, the ratio of WT to all tumors irregularly changed. Furthermore, the total number of parotidectomies per year increased in time. We investigated whether WT had any increasing trend over the years. The annual percentage change (APC) of WT was calculated, and according to the segmented regression analysis, the APC was insignificant (APC = 4.3, 95% CI = - 3.6-12.9, P = 0.300). CONCLUSION: The incidence of WT has increased across the world. However, in our study, no significant APC was observed according to the segmented regression analysis.

Systemic steroid versus combined systemic and intratympanic steroid treatment for sudden sensorineural hearing loss.

OBJECTIVE: The aim of this study was to evaluate the effectiveness of oral steroid treatment versus combined oral and intratympanic dexamethasone injection for idiopathic sudden sensorineural hearing loss. METHODS: This was a retrospective case review in which 30 patients in the oral steroid group and 39 patients in the combined oral and intratympanic steroid injection group were compared. RESULTS: The comparison of the initial pure tone audiometry (PTA) threshold results revealed a significant difference between the systemic steroid (SS) group and the systemic and intratympanic steroid group. The initial PTA was 74.33 ± 22.64 dB (mean ± SD) in the SS group and 87.49 ± 26.22 dB (mean ± SD) in the intratympanic steroid group. The difference in the initial PTA results was statistically significant between the SS group and intratympanic steroid group (P < 0.05, P = 0.032). The pure-tone gain in the SS group was 20.97 ± 27.47 dB (mean ± SD), and that of the group treated with both systemic and intratympanic steroids was 19.36 ± 22.16 dB (mean ± SD) (P = 0.49). CONCLUSIONS: The results of this study indicate that, in sudden sensorineural hearing loss, the administration of intratympanic steroids in conjunction with SS therapy appears to have the same effect on the restoration of hearing "as the effect obtained using SS therapy alone."

The polymorphisms of the MBL2 and MIF genes associated with Pediatric Cochlear Implant Patients.

OBJECTIVES: Mannose-binding lectin and macrophage migration inhibitory factor gene polymorphisms are associated with several acute/chronic autoimmune or inflammatory diseases. The aim of this study was to investigate if there was any association between mannose-binding lectin 2 (MBL2) and macrophage migration inhibitory factor (MIF) gene polymorphisms and profound congenital sensorineural hearing loss in children who underwent cochlear implantation. METHODS: A total of 62 patients with congenital hearing loss and 80 age- and sex-matched healthy controls were evaluated for codon 54 A/B polymorphisms in MBL2 and the-173 G/C polymorphism in MIF by using the polymerase chain reaction and restriction fragment length polymorphism method. RESULTS: The frequency of the BB genotype of MBL2 and MIF -173 GC genotype were statistically significantly higher in the patient group than in the controls (p=0.0127, p=0.0408, respectively). CONCLUSION: In this study, we found that a subject who is homozygous for the variant allele B of codon 54 of the MBL2and heterozygous for variant allele C of -173 MIF has a risk factor for sensorineural hearing loss.
