Endoscopic butterfly cartilage myringoplasty

Abstract Conclusion: Based on the results of this study, it is believed that, in appropriate patients with tympanic membrane perforation, the endoscopic butterfly cartilage myringoplasty can be applied, with a shorter operation time, high graft success rate, and low risk of complications. Objective: The aim of this study was to evaluate the results of the endoscopic butterfly cartilage myringoplasty in terms of the graft success rate and hearing gain. Methods: Forty-five ears of the 42 patients who were subjected to endoscopic butterfly cartilage myringoplasty surgery between January 2013 and December 2014 were included in this study. The archival records of the patients were reviewed retrospectively, evaluating the pre-operative and post-operative hearing results and post-operative graft success rates in the early and late periods. Results: The graft success rates were 97.8% (44/45 ears) and 95.6% (43/45 ears) at the post-operative 1- and 6-month follow-ups, respectively. When the post-operative air conduction hearing thresholds were compared, significant improvement was seen at post-operative 1- and 6-month follow-ups in the hearing thresholds, when compared to the pre-operative levels (p < 0.001).

Endoscopic cartilage tympanoplasty in chronic otitis media

OBJECTIVES The use of endoscopic techniques is becoming more widespread in otological and neuro-otological surgery. One such procedure, endoscopic tympanoplasty, is used in chronic otitis media treatment. This study aimed to analyse the results of endoscopic transcanal cartilage tympanoplasty. METHODS Data of tubotympanic chronic otitis media patients who underwent transcanal endoscopic type I cartilage tympanoplasty between June 2012 and May 2013 were analysed. The main outcome measures were graft success and hearing improvement. RESULTS Graft success rates were 94.3 per cent and 92.5 per cent at post-operative months one and six, respectively. Post-operative air-bone gap values were significantly improved over pre-operative values (p < 0.01). CONCLUSION Transcanal endoscopic type I cartilage tympanoplasty is a minimally invasive, effective and reliable surgical treatment option for chronic otitis media.

Frontal sinus asymmetry: Is it an effect of cranial asymmetry? X-ray analysis of 469 normal adult human frontal sinus

Background and Aims: There is no study in the literature that investigates an asymmetric morphological feature of the frontal sinus (FS). Materials and Methods: Four hundred and sixty-nine consecutive direct X-rays of FSs were analyzed for the asymmetry between the right and left sides. When an asymmetry in the height and contour of the FS existed, this difference was quantified. Results: Of the 469 patients, X-rays of 402 patients (85.7%), there was an asymmetry between right and left sides of the FS. Of these 235 (50.1%) were dominant on the left side, whereas 167 (35.6%) were dominant on the right, the sinuses of remaining 67 patients (14.3%) was symmetric. Statistical Analysis: The comparisons between parameters were performed using Wilkinson signed rank test. The relationship between handedness and sinus asymmetry was also examined by two proportions test. There is statistically significant difference between the dominance of left and right FS. Conclusions: Hemispheric dominance may have some effect (s) of on sinus asymmetry of the human cranium. Surgeons sometimes enter the cranium through the FS and knowledge of asymmetric FS is important to minimize surgical complications.

Diagnostic value of the wideband acoustic absorbance test in middle-ear effusion

OBJECTIVES This study aimed to investigate the diagnostic value of wideband acoustic absorbance testing in otitis media with effusion. METHODS This prospective study compared middle-ear wideband acoustic absorbance rates in three paediatric patient groups: a healthy group of 34 volunteers; 48 patients diagnosed with otitis media with effusion; and 28 patients with chronic effusion but no sign of effusion during myringotomy. The diagnostic value of absorbance testing was analysed with the receiver operating characteristic test. RESULTS The wideband acoustic absorbance rate was significantly lower in the otitis media with effusion group than in both the otitis media and healthy groups at the 0.375-2 kHz averaged mean absorbance (p < 0.017 and p < 0.001, respectively). Receiver operating characteristic analysis showed the highest diagnostic value for the 0.375-2 kHz averaged mean (area under the curve 0.984), followed by those at 1 and 1.5 kHz (area under the curve: 0.973 and 0.967, respectively). CONCLUSION The wideband acoustic absorbance test is more accurate for detecting middle-ear effusion compared with conventional 226-Hz tympanometry. Its practicality and objectivity suggest that the wideband acoustic absorbance test may be a better alternative for diagnosing otitis media with effusion.

Acute airway compromise due to ruptured inferior thyroid artery aneurysm

A cervical hematoma secondary to the spontaneous rupture of an aneurysm is an uncommon but catastrophic life-threatening condition because it can potentially obstruct the airway. Inferior thyroid artery aneurysm and rupture is a very rare clinical entity and only a limited number of cases have been reported in the literature. In this article, we present the case of a female patient who suffered from a rapidly enlarging cervical mass followed by a rapid onset of dyspnea as a result of rupture of an inferior thyroid artery aneurysm. The diagnosis was confirmed by magnetic resonance angiography, and delayed surgery resulted in an uneventful outcome. We aim to draw the attention of emergency physicians to this rare condition.

Skin Prick Test Reactivity in Patients with Chronic Eczematous External Otitis

Objectives To investigate the incidence of skin prick test (SPT) positivity in patients with eczematous external otitis. Methods Forty-six patients with eczematous external otitis and forty-four healthy volunteers were included in the study. All the patients were skin-tested by prick test. Reactions were assessed by the degree of redness and swelling and the size of the wheal produced. Results According to SPT positivity and total immunoglobulin E values, the difference between the study and the control groups was statistically significant (P<0.05). The most common skin reactions were against to mites and grasses in this study. Conclusion Eczematous external otitis is perhaps the most difficult to treat of all forms of external otitis because the provocative agents usually remain undiagnosed. Patients suffering from eczematous external otitis symptoms should be investigated for allergens and be informed for prevention of the causative agents. SPT might be performed in cases of prolonged or treatment-resistant external otitis.

High sensitization to house-dust mites in patients with allergic rhinitis in the eastern Black Sea region of Turkey: A retrospective study.

Objectives Identification of the most common aeroallergens to which patients are sensitized in a specific area is important in the diagnosis and treatment of allergic rhinitis (AR). We determined the distribution of aeroallergens, detected by skin-prick tests (SPT), in adult patients with AR in the Eastern Black Sea region of Turkey and compared the results with the other regions of Turkey and in the world. Methods The medical records of SPT performed on 1457 patients with symptoms of AR (with regard to the Allergic Rhinitis and its Impact on Asthma 2008 guidelines) between March 2010 and March 2013 were analyzed retrospectively. SPT were carried out with the same panel, which included grass; weeds; trees; mold; epidermal mixtures; and with two house-dust mite (HDM) extracts, Dermatophagoides pteronyssinus and Dermatophagoides farinae. Results In 1229 of 1457 patients (84.4%), there were positive reactions for at least one aeroallergen on the SPT. The most common aeroallergen was the HDM D. pteronyssinus (84% [n = 1033]) followed by D. farinae (78.2% [n = 962]). Grass pollen sensitivity (70.8% [n = 871]) was higher than tree or weed pollen sensitivity in this region. Conclusions The most common aeroallergens in AR are HDMs of D. pteronyssinus and D. farinae in the Eastern Black Sea region in Turkey. Our study may help in developing environmental control strategies for AR.

Effects of chronic exposure to electromagnetic waves on the auditory system

Abstract Conclusion: The results support that chronic electromagnetic field exposure may cause damage by leading to neuronal degeneration of the auditory system. Objectives: Numerous researches have been done about the risks of exposure to the electromagnetic fields that occur during the use of these devices, especially the effects on hearing. The aim of this study is to evaluate the effects of the electromagnetic waves emitted by the mobile phones through the electrophysiological and histological methods. Methods: Twelve adult Wistar albino rats were included in the study. The rats were divided into two groups of six rats. The study group was exposed to the electromagnetic waves over a period of 30 days. The control group was not given any exposure to the electromagnetic fields. After the completion of the electromagnetic wave application, the auditory brainstem responses of both groups were recorded under anesthesia. The degeneration of cochlear nuclei was graded by two different histologists, both of whom were blinded to group information. Results: The histopathologic and immunohistochemical analysis showed neuronal degeneration signs, such as increased vacuolization in the cochlear nucleus, pyknotic cell appearance, and edema in the group exposed to the electromagnetic fields compared to the control group. The average latency of wave in the ABR was similar in both groups (p > 0.05).

An evaluation of peripheral arterial tonometry for the diagnosis of obstructive sleep apnea

Objective: Peripheral arterial tonometry (PAT) as a portable method of monitoring sleep quality is a relatively recent innovation. The aim was to compare the results of PAT and polysomnography (PSG) and to evaluate the role of PAT in diagnosing obstructive sleep apnea syndrome (OSAS). Methods: This study included adult patients who admitted to ENT clinic with OSAS complaints (excessive daytime sleepiness, snoring, and witnessed apnea), undergone sleep monitorization using PAT system (WatchPAT 200TM; Itamar Medical Ltd., Caesarea, Israel) and had single-blind, level 1 polysomnography at sleep laboratory of Chest Diseases Department. Results: For the two sleep monitoring sessions as conducted at different times: the apnea-hypopnea index (AHI) and respiratory disturbance index (RDI) values were strongly correlated between sessions (r=0.749, r=0.753; p<0.001). The oxygen desaturation index (ODI) values were very strongly correlated (r=0.861; p<0.001). When the AHI scores calculated using PAT for the patients enrolled in the trial were taken into consideration; 89.7% of the patients were correctly diagnosed with OSAS (AHI≥5); for RDI calculated (RDI≥5) using PAT, 100% of OSAS diagnoses were correct; for AHI values calculated with the PAT method, taking 15 as cut-off point, the sensitivity was found to be at an extremely high level of 96.1%. Conclusion: PAT and PSG values were highly correlated. This finding demonstrated that the reproducibility of the results obtained with PAT was also high. This study shows that PAT can be used as a screening test for OSAS and in a group of patients who are highly suspected for OSAS.

The Effects of Curcumin on Wound Healing in a Rat Model of Nasal Mucosal Trauma

We explored the effects of topical curcumin on the healing of nasal mucosal wounds. A total of 32 Sprague-Dawley Albino rats were randomized in equal numbers into four groups, and unilateral nasal wounds were created using an interdental brush. Group 1 (the sham-control group) contained untreated rats with traumatized right-side nasal cavities; Group 2 and 3 rats were similarly traumatized and treated with topical curcumin (5 and 10 mg/mL) dissolved in dimethyl sulfoxide daily for 7 days after trauma; Group 4 rats were treated with topical dimethyl sulfoxide only. All rats were decapitated on day 15 and the healing sites evaluated by blinded observers in terms of the presence of cellular hyperplasia, goblet cell hypertrophy and degeneration, leucocytic infiltration, ciliary loss and degeneration, edema, and vascular dilation. On histopathological evaluation, all of cellular hyperplasia, leukocytic infiltration, and edema were significantly reduced in Group 3 compared with Group 1 (p = 0.001, p = 0.004, and p = 0.008, resp.). Thus, curcumin reduced the inflammatory response and significantly accelerated wound healing.
