    Approaches to twisted noses and results of treatment
    (2002) Ozturan O.; Miman M.C.; Yigit B.; Cokkeser Y.; Kizilay A.; Aktaş D.
    OBJECTIVES: The aim of this study was to address the multiplicity of surgical techniques and pitfalls in the treatment of twisted noses. PATIENTS AND METHODS: Fifty-nine patients (43 males, 16 females; mean age 27 years; range 17 to 47 years) with vertical axis deviation of the nose were surgically treated. Thirty patients had C-type and 29 patients had I-type twisted noses. Deviation angles were measured before nd at least six months after the operation. Correction of deviations was graded according to the ideal angular values and the two groups were compared. RESULTS: Significant correction was achieved in both types of twisted noses (p < 0.01). The results of the I-twisted noses were significantly closer to the ideal angles compared to those of the C-twisted noses (p < 0.05). Three patients underwent revision surgery. CONCLUSION: To correct functional and aesthetic problems in twisted noses, an external approach can be employed to straighten the nose by releasing, mobilizing, aligning and reinforcing the nasal anatomic structures. Cartilage grafts may be used to camouflage persistent deformities. C-twisted noses require more experience in, and familiarization with, a large number of surgical techniques.

    Bacterial etiology of otitis media with effusion; focusing on the high positivity of Alloiococcus otitidis
    (2002) Kalcioglu M.T.; Oncel S.; Durmaz R.; Otlu B.; Miman M.C.; Ozturan O.
    The etiology of otitis media with effusion (OME) is unclear. The bacterial analyses of middle ear effusion (MEE) in OME may reveal important information regarding its etiology. Alloiococcus otitidis, Heamophilus influenzae, Streptococcus pneumoniae and Moraxella catarrhalis were investigated by using microbiologic culture and a multiplex PCR method in the middle ear fluid of 32 children (54 samples) with chronic OME. PCR yielded positive results in 18 (33.3%) middle ear effusions while culture resulted positive for 3 (5.6%). The PCR method detected A. otitidis in 10 (18.5%) specimens, H. influenzae in 7 (13%), M. catarrhalis in 4 (7.4%) and S. pneumoniae in 2 (3.7%) specimens. The multiplex PCR method enhances the detection rate significantly compared to that of the conventional culture method. A. otitidis is the most common detected pathogen in the MEE of the OME.

    Bending of the upper lateral cartilages for nasal valve collapse.
    (2002) Ozturan O.; Miman M.C.; Kizilay A.
    BACKGROUND: As a consequence of removal of the nasal hump, the upper lateral cartilages are separated from the septal cartilage in reductive rhinoplasty. A decrease in the nasal airway cross-sectional area and collapse of the internal nasal valve (INV) are inevitable unless additional surgical measures are taken. OBJECTIVE: To determine the efficacy of the horizontal mattress bending suture in treating patients with nasal valve collapse. METHODS: Each upper lateral cartilage was separately bent to a certain degree with a horizontal mattress suture following nasal dorsum reduction in the external septorhinoplasty as a preventive or corrective measure for the INV stenosis. The efficacy of this suture was assessed in 28 patients who presented with tension nose by comparing the INV angles preoperatively and 12 months postoperatively, as determined photographically by means of a rigid nasal endoscope. RESULTS: The mean +/- SD preoperative INV angle was calculated as 9.1 degrees +/- 4.2 degrees (range, 0 degrees -18.3 degrees ). The mean postoperative INV angle was increased to 25.3 degrees +/- 3.8 degrees (range, 18.4 degrees -34.5 degrees ) (P<.001). CONCLUSIONS: This method reconstitutes the normal anatomy of the INV, reestablishes stiffness or resistance of the nasal side walls so that they do not bend inwardly with inspiration, improves the airflow at this area, and avoids postoperative nasal valve stenosis in functional-cosmetic rhinoplasty cases that require considerable nasal hump reduction.

    Bilateral aural myiasis (Wohlfahrtia magnifica): a case with chronic suppurative otitis media.
    (2010) Bayindir T.; Miman O.; Miman M.C.; Atambay M.; Saki C.E.
    Myiasis is a disease caused by fly larvae and aural myiasis is a rare clinic condition often occuring in children or mentally retarded people. We report the case of an unusual presentation of a bilateral aural myiasis in a mentally retarded patient with bilateral chronic otitis media caused by the third instar larvae of Wohlfahrtia magnifica. Two larvae were located on the other ear canal while two additional larvae were located in the middle ear cavity and were removed through perforation of the tympanic membrane. Treatment of aural myiasis is based on removal of the maggots and cleansing of the ear with ethanol, chloroform or physiological saline. Physiological saline is preferred in patients who have tympanic membrane perforation. Myiasis is related to personal hygiene. Therefore, in order to decrease the incidence of these infestations, care and hygiene standards should be carried out for those at risk.

    A case of Ewing's sarcoma in the mandible and the skull base.
    (2003) Kalcioglu M.T.; Oncel S.; Miman M.C.; Erdem T.; Mizrak B.
    A thirteen-year-old boy with Ewing's sarcoma was presented. The treatment was considerably delayed because of the initial diagnostic difficulties due to its insidious presentation and the unwillingness of the child's parents to further investigations and treatment. During a three-year delay, the tumor turned out to be a gross painful mass from a painless lesion. Cranial computed tomography and magnetic resonance imaging with contrast showed a destructive lesion extensively involving the right mandible and the skull base, with invasion to the intracranial space. Facial and intratemporal portions of the mass were removed totally, but the intracranial extension could not be totally excised because of cavernous sinus involvement. Histologic and immunohistochemical findings were consistent with the diagnosis of Ewing's sarcoma. The patient received systemic chemotherapy and radiotherapy following surgery. A month after radiation therapy, radiologic investigations showed a lung mass suggestive of metastasis. He died two days after hospitalization, from an intracranial hemorrhage associated with the intracranial mass.

    Comparison of clinical differences between patients with allergic rhinitis and nonallergic rhinitis
    (Medquest Communications LLC, 2013) Akarcay M.; Miman M.C.; Erdem T.; Oncel S.; Ozturan O.; Selimoglu E.
    We conducted a retrospective study to investigate the clinical differences between subtypes of rhinitis patients. Our findings were based on a detailed history and nasal examination. The study population was made up of 910 patients who had at least two rhinitis symptoms. These patients were categorized into one of three rhinitis groups: nonallergic rhinitis (NAR), seasonal allergic rhinitis (SAR), and perennial allergic rhinitis (PAR); there were 212 patients (23.3%) in the NAR group, 473 (52.0%) in the SAR group, and 225 (24.7%) in the PAR group. In addition to demographic data, we compiled information on the season when each patient presented, specific symptoms and their triggers, parental history, associated allergic diseases (e.g., skin, lung, and eye allergies), and nasal examination findings. The SAR patients represented the youngest of the three groups. Most SAR patients presented in spring and summer, and this group had the highest incidence of eye itchiness, pharyngeal itchiness, eye redness, and palatal itchiness. In terms of triggering factors, a visit to a green area was significantly more common in the SAR patients, while detergent odor, sudden temperature change, and cold air were significantly more common in the NAR patients. On nasal examination, a pale nasal mucosa was significantly more common in the NAR group. In clinical practice, it is crucial to differentiate between allergic and nonallergic rhinitis. We conclude that relevant information from the history can predict allergic rhinitis. Future studies of prevalence should take into consideration the important findings of our study, including the significance of age and the seasonality of exacerbation of rhinitis symptoms.

    Current value of nasal nitric oxide measurement in rhinology
    (2004) Oh C.K.; Miman M.C.; Duncavage J.A.
    Purpose of review: Since the first description of nitric oxide in the exhaled breath of humans by Gustafsson et al., there has been enormous interest in the study of nitric oxide and its role in the nose and paranasal sinuses. The aim of this review is to present the current knowledge about nasal NO: its physiology, novel methods of detection and measurement, and implications in sinonasal disease, focusing on the recent data from the literature. Recent findings: Nitric oxide production is known to be produced in the nose at the apical tip of the ciliated respiratory mucosa. A new study has localized nitric oxide production in the pericytes and osteocytes of nasal turbinates. Studies have also discovered the efficacy of offline measurement techniques showing high correlation between standard online measurements with offline techniques. In an interesting study examining the influence of maxillary ostium size and nasal nitric oxide levels, decreased nitric oxide levels found with larger size ostia may eventually influence our approach to sinus surgery. Summary: Nasal nitric oxide has been an ever-increasing topic of interest to both the allergist and the head and neck surgeon. The recent advances in the study of nasal nitric oxide as it relates to sinonasal disease and nasal physiology are discussed and important new findings are highlighted.

    Determination of allergen-specific IgE in patients with atopy or allergy symptoms
    (2003) Miman M.C.; Ozerol I.H.; Ozturan O.; Erdem T.
    OBJECTIVES: We investigated the role of specific IgE assay in the diagnosis in patients found to be atopic or allergic by history and physical examination. PATIENTS AND METHODS: Serum specific IgE levels were measured by the chemiluminescent assay in 143 adults (58 females, 85 males; mean age 34.3 years; range 16 to 62 years) and in 113 children (62 girls, 51 boys; mean age 10.2 years; range 5 to 16 years) with rhinitis, asthma, or dermatitis. The results were analyzed in six groups depending on the specific IgE level (no specific IgE, very low, low, moderate, high, and very high levels). The specific IgE threshold for a negative or positive result was accepted as 0.70 IU/ml. Allergen-specific IgE antibodies were sought for 35 allergens in adults, and for 19 allergens in children. RESULTS: Specific IgE levels were positive (>0.70 IU/ml) in 92 adults (64.34%) and in 50 children (44.25%). Hypersensitivity to individual allergens ranged between 20.08% and 41.96% in adults, and between 17.70% and 28.32% in children. Fourteen adults and eight children showed sensitivity to a single allergen; the remaining patients were sensitive to at least two allergens. CONCLUSION: Detection of sensitivity to allergens is complementary to findings obtained by history and physical examination and may help to reveal allergic etiology in patients presenting with a similar symptom profile.

    The effect of endoscopic sinus surgery on quality of life
    (2003) Akarçay M.; Kizilay A.; Miman M.C.; Cokkeser Y.; Ozturan O.
    OBJECTIVES: We assessed the effects of endoscopic sinus surgery on quality of life of patients with nasal polyposis or chronic sinusitis. PATIENTS AND METHODS: Thirty patients (5 females, 25 males; mean age 36 years; range 17 to 58 years) who underwent endoscopic sinus surgery were prospectively evaluated. The diagnoses were nasal polyposis in 15 patients and chronic sinusitis in 15 patients. Primary and revision operations were performed in 23 patients and seven patients, respectively. The quality of life was evaluated before and six months after surgery with the use of the Chronic Sinusitis Survey (CSS), and Medical Outcomes Study Short Form-12 (SF-12). Prior to administration, the two questionnaires were translated and adapted to Turkish. Computed tomography (CT) findings were scored before and six months after surgery according to the Lund-Mackay system. The results of the surveys were compared with CT scores. RESULTS: The postoperative SF-12 and CSS scores of all the patients improved significantly. Computed tomography scores were not found in correlation with improvements in the SF-12 and CSS scores. CONCLUSION: Endoscopic sinus surgery results in significant improvement in the quality of life of patients with nasal polyposis and chronic sinusitis, which may not be reflected by CT scores.

    A functional and aesthetic solution for saddle nose deformity: the use of the inferior turbinate bone.
    (2003) Ozturan O.; Erdem T.; Miman M.C.; Erguvan R.
    The use of a new autologous material, the inferior turbinate bone, for nasal augmentation is presented together with surgical treatment of a 24-year-old male patient with moderately severe saddle nose deformity. In the postoperative period, no complications were observed. Photographs and three-dimensional computed tomography views obtained 13 months after the operation showed that the reconstruction area was highly free of postoperative resorption. The patient's complaints disappeared, and he was satisfied with functional and cosmetic results. Moreover, a histologic evaluation which was made to assess the depth of the glandular component showed that the inferior turbinate bone could be used over the nasal dorsum in a smoother shape, retaining its overlying soft tissue.

    An important procedure in ossiculoplasty: Autoclaving the ossicles
    (2003) Miman M.C.; Cura O.; Erdem T.; Kirazli T.; Öztop F.; Özturan O.; Öncel S.
    Autoclaving of the ossicles prior to ossiculoplasty is a very important procedure in surgery of cholesteatomatous chronic otitis media. Autoclaving allows the reuse of the ossicles removed from patients with cholesteatomatous chronic otitis media as an autograft. It also allows utilization of the malleus, incus and stapes taken from cadavers or of the uneroded malleus and incus removed from patients undergoing non-functional middle ear surgery chosen carefully with detailed history and laboratory analysis. The powerful disinfecting effect of the sterilising procedures of the homografts inactivates prion proteins which cause degenerative encephalopathies. In various studies, it has been concluded that autoclaving does not alter the matrix of the bone which is responsable for its biophysical properties, whereas it removes all viable cells within the bone and denatures the soft tissue attached to the surface of the ossicle. We have also found confirming histological results in our two previous studies published in 1999 and 2001. It is usually recommended that soft tissue on the surface of the ossicles is removed before autoclaving. It is also sufficient to autoclave the ossicles at 134°C, and at 2.5 atmosphere pressure for 5 minutes in a flash autoclave. The autoclaving time of the homograft ossicles must be longer, for 20 minutes. Following the autoclaving, these homograft ossicles should be kept at pH 5.6 for 3 days, then use a solution of 0.5 % formaldehyde at pH 7 and 4°C for 21 days and it should be washed with physiologic saline solution three times for 7 minutes before use. Depending on the results obtained from our planned comparative experimental study, there will be no need for additional formaldehyde fixation procedure after autoclaving and the autoclaved ossicles will be used immediately without preservation in formaldehyde solution for 24 days.

    Laryngotracheal reconstruction of the congenital glotto-subglottic stenosis with autogenous thyroid cartilage interposition: a case report.
    (2002) Ozturan O.; Kizilay A.; Miman M.C.; Oncel S.; Kalcioglu M.T.; Erdem T.
    Surgical correction of grade III glotto-subglottic stenosis in a two-month-old girl was illustrated in a staged manner. Firstly, a silicone keel was placed via anterior thyrotomy following a tracheotomy. Secondly, laryngotracheal reconstruction was performed by interposing an autogenous thyroid cartilage anteriorly between the edges of the longitudinally divided cricoid cartilage and the upper tracheal rings. A stent was maintained for two months. The glottis and subglottis appeared patent and healed following removal of the stent. A meaningful voice and rather comfortable respiration were observed during a 13-month follow-up. The use of thyroid cartilage autograft offers many advantages in laryngotracheal reconstruction with considerably less technical difficulty.

    Laser assisted eustachian tuboplasty: a case report
    (2005) Erdem T.; Ozturan O.; Miman M.C.; U?raş M.
    Surgical treatment of eustachian tube dysfunction is still challenging. Placement of a transtympanic ventilation tube may not be successful and may require multiple applications. We presented a 47-year-old male patient with chronic recurrent otitis media with effusion and retraction due to eustachian tube dysfunction, in whom the number of previous transtympanic tube insertions amounted to 18. He underwent laser assisted eustachian tuboplasty in both ears with endoscopic guidance under general anesthesia. The mucosal, submucosal, and partially the cartilaginous tissues in the posterior pillow of the nasopharyngeal orifice of the eustachian tube were ablated by Nd:YAG and holmium:YAG laser. Following surgery, air conduction thresholds decreased from 37 dB to 22 dB, and from 38 dB to 33 dB for the right and left ears, respectively. The preoperative tympanogram curve, which was of type B for both ears was found as type C-1 on the right side, and type C-2 on the left. Limited improvement seen in the left ear was ascribed to insufficient ablation of the posterior pillow of the eustachian tube. No complications were encountered within a follow-up of 12 months.

    Metastatic spread of occult papillary carcinoma of the thyroid to the parapharyngeal space: a case report.
    (2003) Erdem T.; Miman M.C.; Oncel S.; Mizrak B.
    Metastasis from thyroid carcinomas to the parapharyngeal space is very rare. A forty-year-old male presented with progressive dysphagia and enlargement in the right upper neck. Examination showed medial displacement of the right palatine tonsil and the lateral oropharyngeal wall. A firm, submucosal mass measuring 4 x 3 cm was palpated. Computed tomography revealed a hypodense and heterogenic parapharyngeal mass with a calcified border. The mass was totally removed by a transcervical approach. Although frozen-section diagnosis was a benign lesion, histopathologic evaluation showed metastasis of papillary thyroid carcinoma to the parapharyngeal lymph nodes. Total thyroidectomy and bilateral selective neck dissection were performed, after which the tumor turned out to be papillary microcarcinoma (0.8 x 0.8 cm) in the right upper lobe of the thyroid gland. No locoregional recurrences or distant metastasis were observed during a three-year follow-up. The differential diagnosis of parapharyngeal masses should include metastatic thyroid carcinomas, for which a lymphatic route has been suggested between the thyroid gland and the parapharyngeal lymph nodes.

    Polyurethane stent obstruction as a cause of recurrent epiphora: Case report
    (Centauro SRL, 2006) Doganay S.; Sarac K.; Miman M.C.; Karadag N.; Cokkeser Y.
    A Song's nasolacrimal duct stent was placed in a patient with epiphora due to primary nasolacrimal duct obstruction and the stent was kept for 32 months. Mitomycin C 0.02% eye drops four times a day were prescribed for four weeks following polyurethane stent placement procedure. No epiphora-related complaints occurred for thirty months after then the epiphora started. Nasolacrimal stent was removed from nasal cavity endoscopially and the tissues within the extruded stent were examined histopathologically. The patient's complaints were relieved following stent removal. Dacryocystogram revealed normal passage and a filling defect within the lacrimal sac. Macroscopic evaluation of the stent revealed a firm mass in the stent mushroom, causing complete obstruction. Pathological examination of the mass revealed chronic inflammation, increased connective tissue and vascular proliferation. N asolacrimal polyurethane stents can be removed easily by nasal approach. Nasolacrimal passage may be left open temporarily after stent removal. The use of Mitomycin C drop is a novel approach in nasolacrimal stent placement cases. However, when the long-term results of endoscopic and external dacryocystorhinostomy are considered, further research is needed on the biocompatibility of stent material.
