Effect of Nasal Soft-Tissue Envelope Thickness on Postoperative Healing Process Following Rhinoplasty.

OBJECTIVE: Understanding the postoperative dynamics of the nasal soft-tissue envelope (NSTE) is necessary to obtain the desired cosmetic results after rhinoplasty. This study was conducted to determine the changes of NSTE thickness and its effects on periorbital edema and ecchymosis following rhinoplasty. METHODS: Thirty-five patients who underwent rhinoplasty were included in the study. Nasal skin and subcutaneous tissue thickness at the tip, supratip, rhinion, and nasion were measured using ultrasonography preoperatively and at the postoperative 3rd and 10th months. Periorbital edema and ecchymosis were evaluated at postoperative days 1, 3, and 7. The patients were categorized as the thick NSTE group (n = 17) and the thin NSTE group (n = 18) according to the preoperative median NSTE thickness. RESULTS: In the thin NSTE group, supratip skin, subcutaneous tissue, and total NSTE thickness were lowest on the preoperative day but no statistically significant difference was found for the thick NSTE group. In the thin NSTE group, total NSTE thickness of the rhinion was highest at the postoperative 3rd month, but in the thick NSTE group, there was no statistically significant difference between postoperative 3rd and 10th months. In both groups, total NSTE thickness of the nasion was highest at the postoperative 3rd month and lowest at the postoperative 10th month. CONCLUSIONS: Supratip fullness occurs more prominent in patients with thin NSTE. Postoperative edema in the rhinion is greater in patients with thin NSTE for the early postoperative period but it lasts longer in patients with thick NSTE. Soft-tissue envelope atrophy at the nasion occurs in both groups in the late postoperative period. Periorbital edema and ecchymosis severity are not affected by NSTE thickness.

Effect of Nasal Skin Type on Skin Problems following Rhinoplasty.

Skin problems following rhinoplasty may cause dissatisfaction concerning the esthetic expectations of the patients. This study was conducted to determine whether nasal skin type has an effect on skin problems after rhinoplasty. Thirty-five patients undergoing rhinoplasty in our tertiary referral center between May 2018 and August 2019 were included in the study. The nasal skin sebum level was measured with Sebumeter preoperatively and patients were divided into two groups according to the median sebum level. Among the 35 patients, half of them with higher nasal skin sebum were categorized as oily skin group (n = 17; 14 males, 3 females; mean sebum level: 200.3 ± 26.9), and the other half were categorized as dry skin group (n = 18; 10 males, 8 females; mean sebum level: 101.9 ± 38). Periorbital edema and ecchymosis were assessed at postoperative days 1, 3, and 7. Acne and seborrhea severity determined with Global Acne Grading System and Seborrheic Dermatitis Area Severity Index the day before operation and postoperative days 7 and 14 and months 1, 3, and 10. Compared with dry skin group, upper eyelid ecchymosis score at postoperative day 7 was statistically higher in oily skin group (p = 0.044). There was no significant difference in upper eyelid edema scores between postoperative days 1 and 3 for oily skin group (p = 0.020). No statistically significant differences were found for acne and seborrhea severity. Nasal skin sebum levels may affect periorbital edema and ecchymosis after the procedure but no significant effect has been observed for acne and seborrhea. Predicting the effect of nasal skin types on these problems may help the surgeon to inform patients more correctly.

Effect of Turbinate Intervention on Nasal Functions in Septorhinoplasty Surgery.

OBJECTIVE: This study was performed to evaluate the effect of inferior turbinate reduction on nasal function. MATERIALS AND METHODS: A total of 32 patients who underwent septorhinoplasty (SRP) operation were included in the study and assigned into 2 groups as group I who received inferior turbinate reduction during SRP operation consisted of 17 patients and the group II who consisted of 15 patients without inferior turbinate reduction. For 2 groups before and after surgery, visual analogue score and findings of the acoustic rhinometry were recorded both before and after decongestion of the nasal mucosa. RESULTS: Postoperative mean visual analogue scale (VAS) scores revealed a statistically significant reduction compared with preoperative values on right and left side of the nasal cavity, both before and after topical decongestion in group I (P < 0.005). Also in group II, the differences of VAS scores for both sides before and after topical decongestion were statistically significant (P < 0.05). Postoperatively, the increase of the volume measurements at the level of pyriform sinüs (VOL2) value on the right side of the nasal cavity before and after decongestion and volume measurements at the level of the nasal valve (VOL1) values on both sides after topical decongestion were found to be statistically significant in group I. When the VAS scores and acoustic rhinometry measurements of group I and group II patients were compared the difference, for before and after topical decongestion, postoperative mean MCA1 (minimal cross-sectional area at the level of the nasal valve) values for left side and right side of nasal cavity were higher in group I than group II and these differences were statistically significant (P < 0.005). CONCLUSIONS: As a result, in the SRP operations, turbinoplasty should be implemented by taking into account the function as well as aesthetic concern. Similar results were obtained in other studies that were carried on.

Effect of Spreader Graft on Nasal Functions in Septorhinoplasty Surgery.

OBJECTIVE: The authors aimed to investigate the effect of spreader grafts on nasal function in septorhinoplasty (SRP). METHODS: A prospective randomized double-blind study was conducted. Thirty patients who underwent SRP operation between October 2011 and January 2013 were divided into 2 equal groups randomly. Fifteen patients underwent SRP surgery without spreader graft technique (Group I) and 15 patients underwent SRP surgery with spreader grafts (Group II). Preoperative and postoperative evaluation included visual analog score (VAS) and acoustic rhinometry test. RESULTS: Visual analog scores and acoustic rhinometry measurements of Group I and Group II patients were compared. Statistically significant difference was found for VAS scores of both the sides of the nasal cavity (both before and after topical decongestion) (P < 0.05), except for the VAS on the right side of the nasal cavity before decongestion (P > 0.05). On acoustic rhinometry test the difference was statistically significant for minimal cross-sectional area (MCA) and volumetric values (VOL)-MCA1, MCA2, VOL1, VOL2 values on the left side of the nasal cavity (both before and after topical decongestion) (P < 0.05) but not on the right side of the nasal cavity (P > 0.05). CONCLUSIONS: Performing spreader graft technique in SRP surgery can prevent the narrowing of the internal nasal valve area after surgery and maintain adequate airway for respiration.

Efficacy comparison of oral steroid, intratympanic steroid, hyperbaric oxygen and oral steroid + hyperbaric oxygen treatments in idiopathic sudden sensorineural hearing loss cases.

Idiopathic sudden sensorineural hearing loss is a rare disorder of unknown pathogenesis in which hearing is lost partially or totally. About 60 treatment modalities have been described. We aimed to compare the efficacy of hyperbaric oxygen, oral steroid, intratympanic steroid therapy and their combinations in idiopathic sudden sensorineural hearing loss patients. Files of patients who were followed up between 2004 and 2010 in our clinic were examined retrospectively. Patients were divided into four groups according to the therapy received: Oral steroid, oral steroid + hyperbaric oxygen, intratympanic steroid and hyperbaric oxygen. Treatment success was assessed by Siegel criteria and mean gains using pre-treatment and post-treatment audiograms. 217 patients and 219 ears were examined. The proportion of patients responding to therapy was the highest in the oral steroid + hyperbaric oxygen group with 86.88% (53/61) followed by the oral steroid group with 63.79% (37/58), the intratympanic steroid group with 46,51% (20/43) and the hyperbaric oxygen group with 43.85% (25/57). The proportion of patients who had complete recovery was the highest in the oral steroid + hyperbaric oxygen group with 42.6% (26/61) followed by the oral steroid group with 19.0% (11/58), the hyperbaric oxygen group with 17.5% (10/57) and the intratympanic steroid group with 11.6% (5/43). The oral steroid + hyperbaric oxygen group has the highest mean hearing gain among all groups (p < 0.05). Idiopathic sudden sensorineural hearing loss patients receiving oral steroid + hyperbaric oxygen combination therapy have a higher likelihood of recovery than patients receiving oral steroids, hyperbaric oxygen or intratympanic steroids alone.

Metastatic basal cell carcinoma.

Basal cell carcinoma (BCC) is the most common skin cancer with a high propensity for local recurrence. The incidence of metastases from BCC is rare. We report a 65-year-old man who had BCC of the medial canthus of the left eye. In the 10-year period, he had been operated on approximately 12 times because of local recurrences. Three years after the last operation, he had a suspicious lesion on the operated area and a lumbar pain. Radiologic examination showed multiple metastatic skeletal and liver lesions. He was referred to the oncology department for radiation therapy and chemotherapy.

Results of hyperbaric oxygen treatment in an at-risk nasal flap following trauma.

Hyperbaric oxygen treatment (HBOT) is widely used in otorhinolaryngology for various purposes. A 20-year-old male patient was admitted following a traumatic nasal wound which occurred several hours prior. He had a nasal glass cut from the radix to the supratip area which was primarily closed by non-absorbable suture. The following day, there was a haematoma and necrosis of the skin. The haematoma was drained under local anaesthesia. Blood supply to the nasal skin was severely compromised and only the columellar artery remaining intact, by definition designating this a difficult to heal wound with the risk of overall healing failure. Necrosis of the skin had developed within the first 24 hours. Accordingly, the patient underwent 30 HBOT sessions (two hours at 253.3 kPa) twice daily for four days and daily thereafter. Antibiotic cover and conservative wound management were also used. Complete healing was achieved without the need for additional surgical intervention. We conclude that timely use of HBOT may be a valuable adjunct to conservative wound management in a case of sharp nasal trauma.

The Efficacy of Intratympanic Steroid Injection in Tinnitus Cases Unresponsive to Medical Treatment.

OBJECTIVES: To examine the efficacy of an intratympanic steroid injection in tinnitus cases unresponsive to medical treatment. MATERIALS AND METHODS: The study was carried out at the Ear, Nose, and Throat Department with 107 patients (46 male, 61 female) between the ages of 20 and 77 with a mean of 42.8 years who had idiopathic tinnitus. Patients were randomized by simple randomization to receive intratympanic dexamethasone or isotonic solution. The patients received six intratympanic injections, two per week for three weeks. Tinnitus handicap index (THI) was performed before treatment and at first week, first month, and six months after the completion of the study protocol. The audiometric tests were performed six months after the treatment. RESULT: In the study group, pretreatment THI and post-treatment first month THI scores and pretreatment THI and post-treatment sixth month THI scores were significantly different whereas the same scores were not significantly different in the control group. The comparison of THI scores between the groups revealed significantly lower scores in the first and sixth months for the study group. CONCLUSION: The effect of the intratympanic injection of dexamethasone on the efficacy of treatment of tinnitus severity was statistically significant.

Evaluation of nasal cytology in subjects with chronic rhinitis: a 7-year study.

BACKGROUND: No diagnostic test had been specifically developed to diagnose nonallergic rhinitis (NAR). Also a negative nasal smear for eosinophils does not rule out the diagnosis. There is a significant diagnostic problem in patients with NAR. How can we solve this problem? OBJECTIVES: Assessment of other cells than eosinophils present in the cytogram such as basophils, neutrophils, and goblet cells may help us to classify and management of diagnostic problem of rhinitis. We sought to characterize the cellular pattern of patients with allergic rhinitis (AR) and compare them with those of NAR. METHODS: According to the skin prick test positivity or negativity, individuals were divided into AR and NAR groups, respectively. Allergic rhinitis group was further divided into seasonal, perennial, and mixed subgroups. Nonallergic rhinitis group was also divided into the following 5 subgroups according to the nasal smear cytologic result: basophilic, neutrophilic, eosinophilic, mixed, and nonallergic noninfectious type. So the frequency rates of the subgroups were calculated and also smear cytologic results were compared. RESULTS: Frequency of AR was approximately equal to NAR in subjects with chronic rhinitis. Neutrophilic, eosinophilic, mixed, and nonallergic noninfectious types were the common types of NAR. An evident nasal eosinophilia was found in AR and eosinophilic NAR, whereas a higher percentage of goblet cells were determined in nonallergic noninfectious rhinitis. There is no significant difference between cytologic results from NAR and AR patients. CONCLUSION: In the patient with positive skin test result, the presence of nasal eosinophilia strongly supports the diagnosis of AR. No diagnostic test had been specifically developed to diagnose chronic NAR. Also, a negative nasal smear for eosinophils does not rule out the diagnosis. Assessment of other cells present in the cytogram such as basophils, neutrophils, and goblet cells may also provide valuable information for differential diagnosis and management of these conditions.

Detection of HHV-8 and HPV in laryngeal carcinoma.

OBJECTIVE: In this study we aimed to investigate the presence of human herpesvirus 8 (HHV-8) and human papillomavirus (HPV) in laryngeal carcinoma. MATERIALS AND METHODS: Fifty patients operated on because of laryngeal carcinoma were included in the study. Forty-seven had squamous cell carcinoma (SCC) whereas three had verrucous carcinoma. Fresh tumoral tissues, or tumoral tissues obtained from archival paraffin-embedded blocks, were examined. HHV-8 DNA and HPV DNA were detected using polymerase chain reaction (PCR) and viral genotypes of HPV were determined via the hybrid capture method. The presence of HHV-8 DNA and HPV DNA were also investigated in normal appearing laryngeal tissue collected from 50 cadavers at autopsy. RESULTS: HPV DNA was detected in seven patients (7/50; 14%) (5 out of 47 patients with SCC (5/47; 10.6%) and two out of three patients with verrucous carcinoma). HHV-8 DNA was detected in five patients and they all had SCC (5/47; 10.6%). One case had both HHV-8 and HPV DNA. None of the control samples from cadavers harbored HHV-8 DNA, or HPV DNA. There was a statistically significant correlation between HHV-8 DNA and HPV DNA positivity and laryngeal SCC (Fisher exact test; p=0.023 for each). No statistically significant correlations were found between the presence of HHV-8 and/or HPV and age, gender, tumor stage, differentiation, the site of the tumor, smoking and alcohol use. CONCLUSIONS: The findings of the present study suggest that beside HPV, HHV-8 might have a role in laryngeal carcinogenesis. Further investigations are necessary to clarify the exact role of these viruses in laryngeal carcinoma.

Simultaneous idiopathic bilateral sudden hearing loss - characteristics and response to treatment.

INTRODUCTION: The aetiology of sudden hearing loss is poorly defined; however, infectious, vascular and neoplastic aetiologies are presumed to be responsible. In addition, the aetiology of bilateral sudden hearing loss is also unknown. OBJECTIVE: The objective of this study is identify the characteristics and treatment response of simultaneous bilateral sudden hearing loss. METHODS: This is a case-control study that practised in tertiary care academic centre. 132 patients with sudden hearing loss who were treated with systemic steroid and hyperbaric oxygen together were included. 26 patients had bilateral sudden hearing loss and 106 patients had unilateral sudden hearing loss. Patients were evaluated with clinical, audiological and radiological examinations and laboratory tests were done. Findings and response to treatment of the patients were compared. RESULTS: The mean ages of patients with unilateral and bilateral sudden hearing loss were 42.0 years and 24.5 years respectively with a statistically significant difference (p<0.001). Immune response markers were more prevalent in bilateral sudden hearing loss. Pre-treatment audiologic thresholds were 69.1dB for unilateral sudden hearing loss and 63.3dB for the left ears and 67.6dB for the right ears for bilateral sudden hearing loss without significant difference. Post-treatment average hearing threshold in unilateral sudden hearing loss was 47.0dB and 55.4dB for the left ears and 59.0 for the right ears in bilateral sudden hearing loss. Average hearing improvement in unilateral sudden hearing loss group was significant (p<0.001) in spite of it was not significant in bilateral sudden hearing loss group for both ears. Between the groups; there was a significant difference for hearing improvement favouring unilateral sudden hearing loss (p<0.001). Tinnitus scores decreased significantly in both groups of patients (p<0.001) in spite of there was no significant difference between the groups of patients. CONCLUSION: Patients with bilateral sudden hearing loss showed lower age, worse prognosis and higher rate of positive immune response markers. Cardiovascular risk factors seem to have an important role in the aetiology of unilateral cases whereas this importance was not present in bilateral ones.

Nasal sound analysis: a new method for evaluating nasal obstruction in allergic rhinitis.

OBJECTIVE: Current measurements of nasal obstruction are unreliable and may be improved with the development of new techniques. The effectiveness of odiosoft-rhino (OR) in the evaluation of nasal obstruction was investigated in a blind comparison at a referral center, institutional practice. PATIENTS: Forty-eight patients with perennial allergic rhinitis and 52 healthy subjects were studied. Nasal endoscopic examination, acoustic rhinometry (AR), and OR were performed and symptom scores compared. MAIN OUTCOME MEASURE: Assessment of nasal blockage with OR method was the main outcome measure. RESULTS: Using the OR technique, significant differences were observed between the patient and control groups. OR data correlated with symptom scores and endoscopic examination. However, this was not observed with AR. A 15.5-dB cutoff point for the left side and 14.5 dB cutoff point for the right side at the 2,000 to 4,000 Hz frequency interval resulted in 93.8% sensitivity and 92.3% specificity and 72.9% sensitivity and 80.8% specificity, respectively. A 8.5-dB cutoff point for the left and right sides at the 4,000 to 6,000 Hz frequency interval resulted in 87.5% sensitivity and 80.8% specificity and 70.8% sensitivity and 78.8% specificity, respectively. CONCLUSION: OR is a simple, noninvasive test for assessing nasal obstruction. The OR technique can detect nasal obstruction with high sensitivity and specificity, and these findings correlate with symptoms and physical examination.

[Aneurysmal bone cyst of the mandible: a case report]. / Mandibula yerlesimli anevrizmal kemik kisti: Olgu sunumu.

Aneurysmal bone cyst is a benign lesion that is more commonly seen in long bones and the vertebra. Its occurrence in the craniofacial region is rare. A nine-year-old boy presented with a well-demarcated, painless, fixed mass, 3 x 3 cm in size, in the left preauricular region, with no fluctuation or crepitation. Computed tomography showed a lesion in the left mandibular ramus with a fluid-fluid level, extending to the mandibular condyle, with erosion to the adjacent cortex. Total curettage was performed via a transoral approach under general anesthesia. Histopathologic diagnosis was made as an aneurysmal bone cyst. No recurrence or complication were seen during a follow-up period of four years.

A study of prognostic factors in sudden hearing loss.

We investigated the prognostic significance of the presence or absence of vertigo and tinnitus, the timing of the initiation of treatment, the type and severity of hearing loss, and age in 72 patients who had experienced sudden hearing loss. We found that the factors associated with a positive prognosis were the absence of vertigo, the presence of tinnitus, initiation of treatment within 7 days, a greater degree of hearing loss in the low frequencies, and a hearing loss of less than 45 dB. Age had no effect on prognosis.

Multiple plaques on the face and neck of a middle-aged man. Diagnosis: secondary syphilis.

Syphilis is an unusual diagnosis in an ENT practice. We evaluated a 55-year-old man who had generalized plaques on his face, neck, and upper extremities. Analysis of skin biopsy and serology specimens revealed that the patient had secondary syphilis. He responded rapidly to treatment. The purpose of this article is to remind otolaryngologists of the signs and symptoms of syphilis so that it can be recognized and treated in a timely fashion.

Spontaneous cerebrospinal fluid rhinorrhea associated with empty sella: a transnasal-transsphenoidal repair of the fistula.

Spontaneous cerebrospinal rhinorrhea is a rare clinical condition. More commonly it develops due to cerebral tumors or hydrocephalus; it is seldom seen in association with empty sella syndrome. A sixty-three-year-old woman who presented with left nasal discharge was hospitalized on the suspicion of CSF rhinorrhea. Analysis of the nasal fluid revealed a clear color, a positive Pandy's test, and a positive result for glucose (72%). On magnetic resonance scans, herniation of the suprasellar cistern was observed into the sellar cavity, and the left sphenoid sinus was filled with contrast medium. The repair of the fistula was performed via a transnasal and transsphenoidal approach. The patient was followed-up for five years without any symptoms or recurrences.

[Hyperbaric oxygen treatment in sudden hearing loss after unsuccessful medical treatment]. / Medikal tedavinin basarisiz oldugu ani isitme kayipli olgularda hiperbarik oksijen tedavisi.

OBJECTIVES: We evaluated the efficacy of hyperbaric oxygen (HBO) treatment in patients with sudden hearing loss unresponsive to medical treatment. PATIENTS AND METHODS: Fifty-one patients (37 males, 14 females; mean age 37 years; range 9 to 63 years) with sudden hearing loss were treated with HBO following unsuccessful medical treatment. Time elapsed from the occurrence of sudden hearing loss ranged between 15 to 45 days. Treatment included two sessions daily for the first three days, followed by a single daily session, to make 20 sessions of 90 minutes. Treatment was discontinued because of early recovery in two patients. Audiometric examinations were made at the end of every five sessions. The patients were classified according to age, gender, and audiogram curves. RESULTS: The mean hearing thresholds were 75.3 dB and 65.6 dB before and after treatment, respectively. Recovery was rated as complete in two patients (3.9%), moderate in two patients (3.9%), mild in 19 patients (37.25%), and as no recovery in 28 patients (54.9%). No significant differences were found between the patient groups in terms of improvement and hearing gain (p>0.05). CONCLUSION: We propose that HBO be resorted to when other means of medical treatment prove unsuccessful in patients with sudden hearing loss.

[Orbital decompression by endoscopic transnasal and transantral approach in thyroid-associated ophthalmopathy]. / Tiroit oftalmopatisinde transantral ve endoskopik transnazal yolla orbital dekompresyon.

OBJECTIVES: We evaluated the results of orbital decompression in patients with Graves' disease. PATIENTS AND METHODS: Orbital decompression was performed by endoscopic transnasal medial wall approach and transantral inferior wall approach in 18 eyes of 12 patients (8 males, 4 females; mean age 41 years; range 24 to 65 years). The degree of exophthalmos was evaluated with the use of the Hertel exophthalmometer preoperatively, and postoperatively in the 24th hour, first and third months. RESULTS: At the end of the third month, exophthalmos decreased by a mean of 4.4 mm (range 3 to 7 mm). Visual acuity and field defects improved considerably in all patients. Complications occurred in three cases (25%) including diplopia, displacement of one eye inferiorly, and maxillary sinusitis caused by the encroachment of the adipose tissue upon the ostium, respectively. CONCLUSION: With the increasing ease of surgical procedures and enhanced experience on the part of surgeons, successful treatment of exophthalmos has become possible with decreased complication rates.

Resumo Introdução A etiologia da perda auditiva súbita ainda não está bem definida; contudo, presume-se que as etiologias infecciosas, vasculares e neoplásicas sejam as responsáveis. Além disso, a etiologia da perda auditiva súbita bilateral também é desconhecida. Objetivo O objetivo desse estudo foi identificar as características e a resposta ao tratamento de perda auditiva súbita bilateral simultânea. Método Este é um estudo de caso-controle realizado em um centro de atenção terciária. Foram incluídos 132 pacientes com Perda Auditiva Neurossensorial Súbita (PANS) que foram tratados com esteroides sistêmicos e oxigênio hiperbárico. 26 pacientes tiveram PANS bilateral e 106 pacientes tiveram PANS unilateral. Os pacientes foram avaliados com exames clínicos, audiológicos, radiológicos e exames laboratoriais. Os achados e a resposta ao tratamento dos pacientes foram comparados. Resultados As idades médias dos pacientes com PANS unilateral e bilateral foram 42,0 anos e 24,5 anos, respectivamente, com diferença estatisticamente significante (p < 0,001). Os marcadores de resposta imune foram mais prevalentes na PANS bilateral. Os limiares audiológicos pré-tratamento foram 69,1 dB para PANS unilateral e 63,3 dB para a orelha esquerda e 67,6 dB para a orelha direita para PANS bilateral, sem diferença significativa. O limiar médio de audição pós-tratamento em PANS unilateral foi de 47,0 dB e 55,4 dB para a orelha esquerda e 59,0 para a orelha direita em PANS bilateral. A melhora auditiva média no grupo com PANS unilateral foi significativa (p < 0,001), apesar de não ser significativa no grupo com PANS bilateral para ambas as orelhas. Houve diferença significativa entre os grupos na melhora auditiva favorecendo a PANS unilateral (p < 0,001). Os escores de zumbido diminuíram significativamente em ambos os grupos de pacientes (p < 0,001), apesar de não ter havido diferença significativa entre os grupos de pacientes. Conclusão Os pacientes com PANS bilateral eram mais jovens, tinham pior prognóstico e maior taxa de marcadores de resposta imunológica positiva. Os fatores de risco cardiovasculares parecem ter um papel importante na etiologia dos casos unilaterais, ao passo que essa importância não estava presente nos casos bilaterais.

Lack of Chlamydophila pneumoniae and predominance of Alloiococcus otitidis in middle ear fluids of children with otitis media with effusion.

OBJECTIVE: To investigate the presence of Chlamydophila pneumoniae and other bacterial pathogens in middle ear effusion samples obtained from children with otitis media with effusion (OME). MATERIALS AND METHODS: Twenty-eight children (mean age 7.03; standard deviation 2.18) with OME unresponsive to medical therapy were included in the study. All of the children underwent ventilation tube insertion under general anesthesia. Eighteen patients were bilaterally affected whereas 10 children had unilateral disease. The middle ear fluids (46 samples in total) were collected during ventilation tube insertion, and were evaluated subsequently for the presence of C. pneumoniae and other bacterial pathogens using polymerase chain reaction (PCR). RESULTS: Although all samples were negative for C. pneumoniae, bacterial DNA was detected in 21 of 46 samples. Overall 40% of the patients (4/10) with unilateral involvement, and 61% of the patients (11/18) with bilateral involvement were positive for bacterial DNA. In 6 patients with bilateral OME bilateral samples were positive, whereas 5 patients with bilateral OME showed only unilateral positivity. According to the results of DNA sequencing analysis, all of the positive samples harbored only one bacterial species. In 12 of 46 samples Alloiococcus otitidis DNA (26%), in 7 Haemophilus influenzae DNA (15%), in one Streptococcus pneumoniae DNA (2%) and in one Moraxella catarrhalis DNA (2%) were present. CONCLUSIONS: Our findings support that C. pneumoniae does not seem to have a role in OME in children whereas A. otitidis was found to be more frequent than the other common pathogens. Further studies are required to elucidate the exact pathogenetic role of these microorganisms in OME.
