The efficacy of tranexamic acid and corticosteroid on edema and ecchymosis in septorhinoplasty.

AbstractThe aim of this study was to investigate the efficacy of tranexamic acid (TA) and methylprednisolone on periorbital edema, ecchymosis, and intraoperative bleeding in patients who underwent open septorhinoplasty (oSRP). Seventy-five patients performing hump extraction and osteotomies were allocated into 3 groups as follows: group 1, 25 patients as control; group 2, 25 patients who were administered oral TA as first dose 1 g starting 2 hours before surgery, 3 g daily in divided doses (1 g, every 8 hours) for 5 days; and group 3, 25 patients who were administered a single dose of 1 mg/kg intravenous methylprednisolone at the beginning of the surgery. Operation time, amount of intraoperative bleeding, and complications were recorded. Scoring of eyelid edema and periorbital ecchymosis was evaluated on postoperative first, third, and seventh days using scale of 0 to 4 by 2 observers. In groups using TA and methylprednisolone, periorbital edema and ecchymosis scores were significantly lower compared with the control group (P < 0.05). No significant difference was seen clinically and statistically in preventing or decreasing both periorbital edema and ecchymosis between group 2 and group 3. Patients given TA showed significantly less intraoperative bleeding compared with controls and patients who were administered methylprednisolone. We observed that the administration of methylprednisolone significantly decreases periorbital edema and ecchymosis. Additionally, our results support that TA use in patients who underwent oSRP with osteotomies was found clinically and statistically effective for prevention of bleeding during oSRP operations and reduction of both periorbital edema and ecchymosis.

Genetic polymorphisms affecting antioxidant enzymes are present in tympanosclerosis patients.

BACKGROUND This study investigated genetic polymorphisms affecting the inducible nitric oxide synthase, superoxide dismutase and catalase enzymes in chronic otitis media patients with and without tympanosclerosis, and the role of genetic susceptibility in the disease aetiology. METHODS A total of 162 patients who underwent surgery for chronic otitis media were divided into two study groups: a tympanosclerosis group and a chronic otitis media group. A third, the control, group comprised 188 healthy volunteers. Venous blood samples were evaluated using reverse transcriptase polymerase chain reaction. RESULTS There was a significant difference in GG genotype distribution of the -277A>G polymorphism in the NOS2 gene between the tympanosclerosis and control groups (p T) polymorphism in the SOD2 gene (p > 0.05). There were significant differences in the TT genotype distribution of the -21A>T polymorphism in the CAT gene between the tympanosclerosis and control groups, and between the chronic otitis media and control groups (p < 0.05). CONCLUSION These results suggest that genetic predisposition may play a role in the aetiopathogenesis of tympanosclerosis.

Open Versus Closed Septorhinoplasty Approaches for Postoperative Edema and Ecchymosis.

Objective:The aim of this study was to compare periorbital edema and ecchymosis seen after closed (endonasal) and open (external) septorhinoplasty (SRP). Methods:In total, 50 patients undergoing hump extraction and osteotomies were allocated to 2 groups. Group 1 consisted of 25 patients who underwent closed SRP. Group 2 consisted of 25 patients who underwent open SRP. Operation time, amount of intraoperative bleeding, and complications were recorded. Scoring of eyelid edema and periorbital ecchymosis was evaluated on the first, third, and seventh postoperative days using a scale of 0 to 4 by the first author. Results:There was no statistically significant difference between the groups in terms of age, sex, or operation time. No significant difference was observed clinically or statistically in the scores of periorbital edema or ecchymosis between groups 1 and 2 on the first, third, and seventh postoperative days (P > 0.05). Conclusions:The authors observed no clinically or statistically significant difference in comparing periorbital edema and ecchymosis seen after closed and open SRP.

Rosai-Dorfman Disease Originating from Nasal Septal Mucosa

Rosai-Dorfman disease is a rarely seen disease with unknown etiology. Extranodal involvement is most commonly seen in the head and neck region. Histopathologically, it is characterized by histiocytic cell proliferation. This paper presents a case of a 15-year-old male patient who presented with nasal obstruction and was surgically treated for a mass filling in the left nasal meatus that was diagnosed to be Rosai-Dorfman disease by histopathological examination.

Giant cell tumor of bone involving the temporomandibular joint and temporal bone.

Giant cell tumor is a primary bone tumor that usually originates from the epiphysis of the long bones and is rarely seen in the cranial region. Most frequently, the tumor develops in the sphenoid and temporal bones in the middle cranial fossa. Giant cell tumor generally shows diversity with respect to benignity, local invasiveness, and histology. Although surgical excision with negative surgical margin may lead to cure, adjuvant radiotherapy is still debated. The patient was admitted with a humming in the left ear and hearing loss. After radiologic examination, a mass with temporomandibular joint involvement as well as temporal and sphenoid bone localization was detected. The patient was diagnosed with giant cell tumor after a biopsy specimen was taken from the mass extending to the middle ear and destroying the temporomandibular joint. The current study reviewed the patients clinical features, diagnosis, and treatment in light of the literature.

The effect of lycopene on experimental myringosclerosis.

OBJECTIVES The aim of this study was to investigate the effect of lycopene on myringosclerosis development using histopathological and immunohistochemical analyses. METHODS Fifty-six intact tympanic membranes of 28 guinea pigs were included in the study. Subjects were randomly divided into four groups (n=7/group). Group I (control group) did not receive any treatment after myringotomy. Group II (lycopene treatment after myringotomy) received oral lycopene (once daily at the same time, 10mg/kg, dissolved in water, administered with a catheter). The treatment lasted seven days. Group III (lycopene treatment before and after myringotomy), received lycopene treatment (same dose and route of administration) for seven days. Myringotomy was performed on day 8, and lycopene treatment was initiated immediately, and continued for seven days (same dose and route of administration). Group IV (lycopene treatment before myringotomy) received lycopene treatment one week before myringotomy using the same method and dose for seven days. Myringotomy was performed on day 8. Lycopene was not administered after myringotomy. Fourteen days after myringotomy, myringosclerosis was evaluated automicroscopically and scored. Following decapitation, bulla were removed and immersed in a 10% formaldehyde solution. Sections were cut for histopathological and immunohistochemical examination, and thickness, sclerosis, inflammation, and collagen-IV accumulation were scored semi-quantitatively. RESULTS In the present study, the level of myringosclerosis was significantly lower in lycopene-treated groups compared to the control group (p<0.05). In addition, thickness, inflammation, sclerosis, and collagen-IV accumulation were significantly lower in the lycopene-treated groups compared to the control group (p<0.05). The timing of lycopene administration - i.e. before and/or after surgery - did not cause any difference with respect to myringosclerosis development. CONCLUSION Lycopene, a strong antioxidant, may represent a good alternative treatment to prevent the development of myringosclerosis.

Association Between Anxiety, Depression, and Salivary Cortisol Levels in Patients with Recurrent Aphthous Stomatitis

Objective Recurrent aphthous stomatitis (RAS) is the most common ulcerative disease of the oral mucosa that commonly affects the general population. The objective of this study was to conduct a research in assesing the relationship between psychological disorders including anxiety, depression and salivary cortisol levels in patients with RAS. Methods Thirty-nine patients suffering from minor RAS were enrolled in the study after obtaining an informed consent. The control group consisted of 25 age and gender matched healthy individuals. All subjects were evaluated by using both psychological tests (Hamiltons anxiety rating scale [HARS] and Hamiltons depression rating scale [HDRS]) and physiological testing instrument (salivary cortisol level). Results While no statistical difference was found between the patients with RAS and controls for both salivary cortisol levels and anxiety, there was statisticaly significant difference between the groups for depression. Conclusion There was no significant increase in salivary cortisol levels in patients with active disease when compared to the healthy subjects. But we found that depression scale values were significantly higher in patients with RAS.

Posttravmatik frontoetmoidal mukopiyosel

Paranasal sinus mucoceles are mucus-containing cystic structures with an epithelial lining that completely fills in the paranasal sinuses. Although they are benign in nature, they may result in the destruction of the surrounding bony structures over time. Clinical findings such as exophthalmia, visual impairment, and diplopia occur due to pressure of the fronto-ethmoidal mucocele on the orbita. Currently, the endoscopic intranasal approach is preferred in the treatment of paranasal sinus mucoceles due to its minimal morbidity and low recurrence rates. Here, we present a patient aged 12 years who had a right fronto-ethmoidal mucopyocele secondary to a probable trauma 2 years prior, which resulted in proptosis due to pressure on the orbita.

Evaluation of the Relationship Between the Air-Bone Gap and Prolonged ABR Latencies in Mixed-Type Hearing Loss.

OBJECTIVE The aim of this study was to determine the air-bone gaps in adults with mixed-type hearing loss using air-conduction auditory brainstem response (ABR) latencies. MATERIALS AND METHODS Thirty adults with mixed-type hearing loss (study group) and 30 adults with normal hearing (control group) were included in this study. Before performing ABR measurements, ear, nose, and throat examinations, pure tone audiometry, speech audiometry, acoustic immittance audiometry, and transient evoked autoacoustic emission testing were performed for all participants. Absolute latencies of I, III, and V waves and interpeak latencies (IPL) at 90 decibel hearing level dB nHL were evaluated and compared with air-bone gap results. RESULTS ABR latencies using click and tone-burst stimulation were obtained and found to be longer in the mixed-type hearing loss group than in the normal hearing group (p<0.05). A moderate positive relationship was detected between the air-bone gap and wave III/V latencies at 0.5/1 kHz, I-V/I-III/III-V IPL at 1 kHz. Only one strong relationship was found between 1 kHz air-bone gap and I-V IPL. CONCLUSION In this study, the magnitude of the air-bone gap could not determined using prolonged ABR latencies. Delays in ABR latencies were observed, but prolonged ABR latencies was not helpful for calculating the air-bone gap on mixed-type hearing loss.

Values Range of Tympanometric Gradient in Otitis Media With Effusion

INTRODUCTION The aim of this study was to establish how reliable a given tympanogram is in predicting the presence or absence of a middle ear effusion, and to provide new views for the diagnostic information of tympanometry. The use of tympanometric gradient in addition to static admittance is the focus of this study. MATERIALS AND METHODS The authors enrolled 146 female and 129 male patients. The participants were allocated into groups as follow: Group A1 consisted of 50 healthy children. Group A2 consisted of 86 children with otitis media with effusion. Group B1 consisted of 85 healthy adults. Group B2 consisted of 54 adults with otitis media with effusion. All diagnostic otoscopic examination and tympanometry were performed in both ears. The authors analyzed the distribution of tympanograms in patients with otitis media with effusion and healthy controls. RESULTS When the right and left ear canal volume of either children or adults with otitis media with effusion compared with healthy controls, no statistically significant different was observed (P > 0.05). On the other hand, the statistically significant difference was detected for the values of compliance, pressure and gradient of either children or adults with otitis media with effusion compared with healthy controls (P < 0.05). CONCLUSION The authors found the values range from 0.01 to 1.52 mL gradients (mean least value 0.15 mL) in adults and the values range from 0.01 to 0.93 mL gradients (mean least value 0.10 mL) in children in the presence of otitis media with effusion. The authors think that tympanometric gradient may be useful to detect the otitis media with effusion.Introduction: The aim of this study was to establish how reliable a given tympanogram is in predicting the presence or absence of a middle ear effusion, and to provide new views for the diagnostic information of tympanometry.
