Primary triple head and neck tumors: Laryngeal squamous cell carcinomas, Kaposi's sarcoma, and non-Hodgkin's lymphoma.

Simultaneously triple head and neck malignancies are extremely rare. We report a case who had epithelial and mesenchymal malignant tumor with lymphoid malignancy in head and neck area. A patient who is 74 year old male patient presented to the otorhinolaryngology department with severe breathing difficulty due to laryngeal mass. The result of laryngeal biopsy was invasive SCCs, so patient underwent total larygectomy and bilateral level 2,3,4 neck disection operation. Primary 3 different type head and neck tumors were observed with histopathological examination. These were orderly invasive SCCs in larynx, B-cell Non-Hodgkin's lymphoma in tongue root and one lymph node of left neck dissection material, Kaposi's sarcoma in one lymph node of right neck dissection material. Although synchronous head and neck tumors occurs very rare with laryngeal carcinoma, the neck dissection materials should be researched for synchronous tumors.

Is Ozone (O3) Treatment Effective in Atrophic Rhinitis? Experimental Animal Study.

INTRODUCTION: Atrophic rhinitis (AR) is a disease characterized by atrophy of the mucosa, submucosa, bone tissue due to an unknown cause and excessive nasal cavity enlargement. The disease still has no complete treatment, and the treatment of the functional loss of atrophic cells in AR is still a matter to be investigated. Ozone (O3) therapy has been shown to enhance cell metabolism, angiogenesis, fibroblast activity, and collagen synthesis. AIM: To determine whether ozone treatment affects the disease histopathologically, in experimentally created AR. Material - Method: Twelve Wistar Hanover strain albino male rats were included in the study. Atrophic rhinitis was induced in animals by administering Pasteurella multocida toxin diluted with saline for 21 days to both nasal cavities. A total of 12 animals included in the study were divided into 2 groups as control and study. Ozone gas (60 µg/mL) was administered rectally to the study group for 21 days. After 2 weeks, the rats were decapitated, the nasal cavities were removed as a block, and atrophic rhinitis parameters (epithelial hyperplasia, goblet cell loss, cilia loss, inflammatory infiltration, and vascular ectasia) were evaluated under light microscopy by histopathological examination and statistically interpreted. RESULT: The incidence of vascular ectasia was significantly lower in the ozone group compared to the control group (p<0.05). There was no significant difference between the groups regarding other histopathologic findings. CONCLUSION: Ozone treatment was moderate at the histopathological level. We concluded that ozone therapy has no or very limited effect on atrophic rhinitis.

Histopathological comparison of bone healing effects of endonasal and percutaneous lateral osteotomy methods in rabbit rhinoplasty model.

INTRODUCTION: Lateral osteotomy is mainly performed either endonasally or percutaneously in rhinoplasty which is a frequently performed operation for the correction of nasal deformities. Both techniques have both advantages and disadvantages relative to each other. OBJECTIVE: The aim of this study was to compare the histopathological effects of endonasal and percutaneous osteotomy techniques performed in rhinoplasty on bone healing and nasal stability in an experimental animal model. METHODS: Eight one year-old New Zealand white rabbits were included. Xylazine hydrocloride and intramuscular ketamine anesthesia were administered to the rabbits. Endonasal osteotomy (8 bones) was performed in Group 1 (n=4), and percutaneous osteotomy (8 bones) in Group 2 (n=4). One month later the rabbits were sacrificed. Bone healing of the rabbits was staged according to the bone healing score of Huddleston et al. In both groups, nasal bone integrity was assessed subjectively. RESULTS: In the percutaneous osteotomy group, Grade 1 bone healing was observed in two samples (25%), Grade 2 bone healing in two samples (25%), Grade 3 bone healing in four samples (50%). In the endonasal osteotomy group, Grade 1 bone healing was observed in 6 samples (75%) and Grade 2 bone healing was observed in 2 samples (25%). In the percutaneous group, fibrous tissue was observed in 2, predominantly fibrous tissue and a lesser amount of cartilage was observed in 2 and an equal amount of fibrous tissue and cartilage was observed in 4 samples. In the endonasal group, fibrous tissue was observed in 6 samples, and predominantly fibrous tissue with a lesser amount of cartilage was observed in 2 samples. In both groups, when manual force was applied to the nasal bones, subjectively the same resistance was observed. CONCLUSION: Percutaneous lateral osteotomy technique was found to result in less bone and periost trauma and better bone healing compared to the endonasal osteotomy technique.

Is submucosal fat injection effective in atrophic rhinitis? An experimental animal study.

Atrophic rhinitis (AR) is a disease characterized by the extensive dilatation of the nasal cavity and atrophy of the mucosa, submucosa and bone tissue. Its etiological factors are unknown. There is not a satisfying treatment yet and the treatment of the functional impairment in the atrophic cells is still subject to investigation. The objective of this study is to determine at the histopathological level the possible effects of the submucosal fat injection in an experimental model of AR. 12 albino Wistar-Hannover male rats were included in the study. AR was induced with the Pasteurella multocida toxin, which was diluted with saline. As one of the rats died during the study, it was excluded from the evaluation. The right nasal cavities of all rats (11 nasal cavities) were defined as the control group (Group 1). Fat tissue obtained from the abdominal area was injected in the seven left nasal cavities (Group 2). All injections, which were done to the abdominal regions were also done in the left nasal cavities of the remaining four rats, which constituted the sham group (Group 3). After 14 days, all rats were decapitated and the squamous metaplasia and keratinization in the superficial epithelium, degeneration, vacuolar changes in the basal layer, congestion, inflammatory infiltration, vascular proliferation and glandular atrophy in the submucosa are histopathologically classified. The results were analyzed with statistical methods. Although glandular atrophy was significantly regressed in the fat injection group (Group 2) compared to other groups (p < 0.05), the remaining parameters did not show any significant difference among these three groups. The histopathological effect of the fat injection was modest. We concluded that fat injection treatment has no or at the most a very limited effect in the treatment of atrophic rhinitis.

Can Serum Neutrophil-to-Lymphocyte Ratio Be a Predictive Biomarker to Help Differentiate Active Chronic Otitis Media From Inactive Chronic Otitis Media?

OBJECTIVES: The authors' aim was to investigate whether serum neutrophil to lymphocyte ratio might be used as a predictive biomarker to help differentiate active from inactive chronic otitis media (COM). METHODS: Two hundred fifty-nine patients having inactive COM received tympanoplasty without mastoidectomy and were identified as Group 1. On the other hand, 254 patients having active COM received tympanoplasty with mastoidectomy and were identified as Group 2. Routine hemogram tests were performed preoperatively for both the groups. By performing a chart review, white blood cell count, red blood cell count, hemoglobin, hematocrit, platelet, and mean platelet volume values were compared between the groups in an age-matched and sex-matched manner. RESULTS: A total of 513 COM patients with age range of 7 to 65 years were included in the study. Two hundred seventy-five patients (53.6%) were male, 238 were (46.4%) female. Preoperatively both serum neutrophil and lymphocyte counts were significantly higher in Group 2 (P = 0.015 and P = 0.004, respectively). However, the neutrophil-to-lymphocyte ratios between the groups were not significantly different (P = 0.511). CONCLUSION: No statistically significant differences were identified from preoperative neutrophil-to-lymphocyte ratios between patients having active COM and inactive COM. LEVEL OF EVIDENCE: Level NA.

The comparison of edema and ecchymosis after piezoelectric and conventional osteotomy in rhinoplasty.

The basic aim of our study is to compare the results of the conventional and piezoelectric osteotomy in rhinoplasty by complete subperiosteal degloving of nasal bone to minimize soft-tissue injury. The study was designed as a prospective, double-blind, randomized, and controlled study. Setting is a tertiary referral hospital in Turkey. Ninety patients who underwent primary open rhinoplasty with osteotomy, performed by either the conventional instruments or the piezoelectric device. The complete subperiosteal degloving of the entire nasal bone was done up to the nasal maxillary sulcus, medial canthus, and nasion in all patients, independent of the type of osteotomy device used. Patients subsequently underwent median-oblique and lateral osteotomy, either with an ultrasonic device or a conventional 2-mm guarded, straight osteotome. The postoperative edema and ecchymosis were evaluated by another surgeon who was blinded to the osteotomy procedure on postoperative days 2 and 7. The edema scores were significantly increased on the second day compared with the seventh day in both groups 1 and 2. However, there was no significant difference between groups. The ecchymosis scores were slightly higher in postoperative day 2, compared with day 7, in both groups 1 and 2, but statistically not significant. This study showed that the main reason edema and ecchymosis are seen post-rhinoplasty is related to soft-tissue injury during osteotomy.

Extended lateral thoracic fasciocutaneous biosynthetic flap for reconstruction of full-thickness partial external ear defects: an experimental study.

External ear reconstruction is a controversial topic in reconstructive plastic surgery. Here, we prepared a pedicled biosynthetic flap for full-thickness, partial ear defects in rabbits. We operated on six adult female New Zealand rabbits weighing 3-4 kg. The dimensions of the lateral thoracic fasciocutaneous flap were 7 × 6 cm. The flap was elevated based on one of the bilaterally located internal thoracic arteries, which were dissected proximally. The pedicled flap was folded in two, and polypropylene mesh was sandwiched in the middle. The flap was adapted to a defect of 3.5 × 3 cm in diameter. In fact, the defect was created before elevation of the flap. Rabbits were followed up for 4 weeks, at the end of which they were killed and their ears were evaluated histopathologically. The survival rate of the rabbits was 100 %. All pedicled biosynthetic flaps were viable, but one showed partial (20 %) necrosis (1/6) and one was partially detached (1/6). Macroscopic (color, thickness, texture) and histological (polymorphonuclear leukocyte invasion in the skin, subcutaneous tissue, and at the junction between the polypropylene mesh and the flap) features of the flap were compared to the ipsilateral ear. A new technique was developed for partial external ear reconstruction with sufficient inner skeletal support and outer skin lining. Level of evidence Level NA.

Polypropylene mesh for nasal septal perforation repair: an experimental study.

The aim of this study is to determine the effectiveness and biocompatibility of polypropylene mesh for the repair of nasal septal perforations in an animal model on rabbits. A full-thickness nasal septal perforation with a diameter of nearly 10 × 10 mm was created on 12 rabbits, and then the perforation was reconstructed with two different methods. We used mucosal flaps and polypropylene mesh as an interpositional graft in group 1. Only mucosal flaps were used for reconstruction and are identified as group 2. After 4 weeks, we removed the nasal septum of the rabbits and performed histopathological examinations for acute rejection, infection, inflammatory response, fibrosis, and granuloma formation. We found perforation closure rates of 75 and 25 % in groups 1 and 2, respectively. Inflammatory response was seen in all specimens of group 1 (100 %). The inflammatory response was +1 in five of the specimens (62.5 %), +2 in one specimen (12.5 %), and +3 in two specimens (25 %). Mild fibrosis around the mesh was detected in four specimens (50 %), medium-level fibrosis was detected in one (12.5 %), and no fibrosis was detected in three (37.5 %). Severe fibrosis was not seen in any specimens. The foreign-body reaction was limited to a few giant cells, and granuloma formation was seen in two specimens (25 %). The propylene mesh showed excellent biocompatibility with the septal mucosa, and it can, therefore, be used for the repair of septal perforation as an interpositional graft safely.

Bacteriological profile in conjunctival, lacrimal sac, and nasal specimens and conjunctival normalization time following external, endoscopic, and transcanalicular multidiode laser dacryocystorhinostomy.

PURPOSE: To compare the conjunctival, lacrimal sac, and nasal flora cultures and conjunctival normalization time following external (EX-), endoscopic (EN-), and transcanalicular multidiode laser (TC-) dacryocystorhinostomy (DCR) and to evaluate the relationship between culture positivity and surgical success. We further performed antibiotic sensitivity analyses for lacrimal sac culture samples. METHODS: A total of 90 patients with primary acquired nasolacrimal duct obstruction were recruited and divided into EX-DCR (n=32), EN-DCR (n=28), and TC-DCR (n=30) groups. Conjunctival, nasal, and lacrimal sac cultures and antibiograms were analyzed. RESULTS: In all three groups, coagulase-negative Staphylococcus (CNS) was predominantly isolated preoperatively from the conjunctiva, nose, and lacrimal sac and postoperatively from the conjunctiva. Preoperative and postoperative conjunctival culture positivity rates were similar between all the groups (p>0.05). A statistically significant difference in the growth rate of culture in the lacrimal sac was observed between the three groups (p=0.001). CNS and Staphylococcus aureus cultures were predominantly sensitive to linezolid, teicoplanin, tigecycline, vancomycin, and mupirocin. Conjunctival normalization times were similar between the three groups (p>0.05). Anatomical and functional success rates were not found to be significantly correlated with preoperative conjunctival and lacrimal sac culture positivity (p>0.05). CONCLUSIONS: Similar rates of preoperative and 1-week postoperative conjunctival culture positivity were observed in all the groups; a significantly lower bacterial growth rate was observed in postoperative conjunctival cultures. CNS was the most commonly isolated organism. Bacterial growth rates in the lacrimal sac samples were significantly higher in the EN-DCR group. Bacterial growth rates obtained preoperatively from the conjunctival and lacrimal sac culture samples were not correlated with DCR success.

Assessment of inferior turbinate radiofrequency treatment: Monopolar versus bipolar.

OBJECTIVE: The aim of this study is to compare the early results of monopolar (MP) and bipolar (BP) radiofrequency (RF) used in inferior turbinate hypertrophy treatment concerning aspects of patient and surgeon comfort. STUDY DESIGN: Prospective randomized single-blind study. MATERIALS AND METHODS: The study included 71 patients with inferior turbinate hypertrophy resistant to medical treatment. BP RF was applied to 36 patients. MP RF was applied to 35 patients. Patients received no other treatment during their 6 months of follow-up examinations. They were evaluated by their symptoms (nasal obstruction severity, nasal obstruction frequency, postnasal drip, nasal crusting, hyposmia, patient satisfaction, and preoperative pain) with a visual analogue scale (VAS) done preoperatively on the 1st and 7th days and then in the 1st, 3rd, and 6th months postoperatively. RESULTS: No significant difference was observed comparing the symptoms of patients after BP and MP inferior turbinate RF in long-term follow-up, whereas patients treated with MP RF showed early improvement in their symptoms on the 1st and 7th days postoperatively when compared to the BP group. The application time of MP RF was longer than that of the BP group. Pain during the operation was reported more frequently in the BP group. CONCLUSION: MP and BP RF treatment showed no difference in long-term efficacy. However, MP RF therapy showed early improvement in symptoms and less pain in patients than in the BP RF group.

Comparison of Frey Syndrome Rates Following Superficial Parotidectomy and Partial Superficial Parotidectomy for Pleomorphic Adenoma.

PURPOSE: Comparison of Frey syndrome rates following superficial parotidectomy and partial superficial parotidectomy for pleomorphic adenoma. METHODS: Fifty patients diagnosed with pleomorphic adenoma and received surgical treatment at the Otolaryngology Department of Bagcilar Training and Research Hospital between January 2009 and October 2015 were reviewed retrospectively. The patients were specifically queried for Frey syndrome symptoms. The syndrome was investigated with Minor starch iodine test. The patients who underwent superficial parotidectomy were compared to those who underwent partial superficial parotidectomy in terms of Frey syndrome development and recurrence. RESULTS: In the partial superficial parotidectomy group, Frey syndrome symptoms were edema and increased sweating and burning sensation on the face in 7 patients (21.9%, P = 0.735). In the superficial parotidectomy group, 5 patients exhibited edema (27.8%), 3 exhibited increased sweating (16.7%), and 5 exhibited burning sensation (27.8%). Minor test results were positive for 7 patients in the partial superficial parotidectomy group (21.8%) and 5 patients were positive (27.8%) in the superficial parotidectomy group. No recurrence was found in either group during the 5-year follow-up. No significant difference was found between 2 groups in terms of postoperative complications and recurrence. CONCLUSION: In terms of their effect on Frey syndrome development, there is no significant difference between partial superficial parotidectomy and superficial parotidectomy.

Bacteriological profile in conjunctival, lacrimal sac, and nasal specimens and conjunctival normalization time following external, endoscopic, and transcanalicular multidiode laser dacryocystorhinostomy / Perfil bacteriológico e tempo de normalização conjuntival de espécimes de conjuntiva, saco lacrimal e nasais após dacriocistorrinostomia externa, endoscópica e transcanalicular com laser de multi diodo

RESUMO Objetivo: Comparar a flora conjuntival, do saco lacrimal e nasal com o tempo de normalização após dacriocistorrinostomia (DCR) externa (EX-), endoscópica (EN-) e transcanalicular a laser de multi diodo (TC-) para correlacionar a positividade da cultura com o sucesso cirúrgico, assim como identificar a sensibilidade aos antibióticos em amostras de saco lacrimal. Métodos: Neste estudo prospectivo, 90 pacientes com obstrução do canal nasolacrimal adquirida primária foram incluídos e divididos em grupos EX-DCR (n=32), EN-DCR (n=28) e TC-DCR (n=30). Culturas e antibiogramas conjuntivais, nasais e do saco lacrimal foram analisados. Resultados: Staphylococcus coagulase-negativo (CNS) foi o organismo predominante isolado no pré-operatório (conjuntiva e nariz), no transoperatório (saco lacrimal) e pós-operatório (conjuntiva), nos 3 grupos. Taxas de positividade de cultura da conjuntiva pré- e pós-operatórias nos três grupos foram semelhantes (p>0,05). A diferença nas taxas de crescimento do saco lacrimal dos três grupos foi estatisticamente significativa (p=0,001). CNS e S. aureus foram mais sensíveis a linezolida, teicoplanina, a tigeciclina, vancomicina e mupirocina. O tempo de normalização conjuntival foi semelhante nos três grupos (p>0,05). Não houve relação estatisticamente significativa entre as taxas de sucesso anatômicas e funcionais e a positividade da cultura conjuntival e de saco lacrimal pré-operatória (p>0,05). Conclusões: Pacientes submetidos a EX-DCR, EN-DCR, e TC-DCR apresentaram positividades de cultura conjuntival semelhantes no pré-operatório e na 1a semana pós-operatória. Houve uma redução significativa na taxa de crescimento das culturas da conjuntiva pós-operatórias. O organismo mais comumente isolado foi o CNS. A taxa de crescimento de bactérias a partir do saco lacrimal foi significativamente maior no grupo PT-DCR. O crescimento bacteriano da conjuntiva no pré-operatório e de amostras do saco lacrimal no transoperatório não se relacionaram com o sucesso da DCR.

Effects of ozone (O3) therapy on cisplatin-induced ototoxicity in rats.

The aim of this study is to investigate the effect of rectal ozone and intratympanic ozone therapy on cisplatin-induced ototoxicity in rats. Eighteen female Wistar albino rats were included in our study. External auditory canal and tympanic membrane examinations were normal in all rats. The rats were randomly divided into three groups. Initially, all the rats were tested with distortion product otoacoustic emissions (DPOAE), and emissions were measured normally. All rats were injected with 5-mg/kg/day cisplatin for 3 days intraperitoneally. Ototoxicy had developed in all rats, as confirmed with DPOAE after 1 week. Rectal and intratympanic ozone therapy group was Group 1. No treatment was administered for the rats in Group 2 as the control group. The rats in Group 3 were treated with rectal ozone. All the rats were tested with DPOAE under general anesthesia, and all were sacrificed for pathological examination 1 week after ozone administration. Their cochleas were removed. The outer hair cell damage and stria vascularis damage were examined. In the statistical analysis conducted, a statistically significant difference between Group 1 and Group 2 was observed in all frequencies according to the DPOAE test. In addition, between Group 2 and Group 3, a statistically significant difference was observed in the DPOAE test. However, a statistically significant difference was not observed between Group 1 and Group 3 according to the DPOAE test. According to histopathological scoring, the outer hair cell damage score was statistically significantly high in Group 2 compared with Group 1. In addition, the outer hair cell damage score was also statistically significantly high in Group 2 compared with Group 3. Outer hair cell damage scores were low in Group 1 and Group 3, but there was no statistically significant difference between these groups. There was no statistically significant difference between the groups in terms of stria vascularis damage score examinations. Systemic ozone gas therapy is effective in the treatment of cell damage in cisplatin-induced ototoxicity. The intratympanic administration of ozone gas does not have any additional advantage over the rectal administration.

Primary small cell carcinoma of the parotid: Fine needle aspiration and immunohistochemical features of a neuroendocrine variant.

Salivary gland small cell carcinoma (SGSmCC) is extremely rare, accounting for less than 1% of salivary gland tumors. A 42-year-old female patient came to the outpatient clinic due to a mass localized in the left submandibular space and that had been growing since 3-4 months. The fine needle aspiration cytology (FNAC) matched with small cell carcinoma (SmCC). As no other focus was detected by computerized tomography (CT), it was accepted as a primary neoplasm of the parotid gland. The histopathological assessment of the excised material and immunohistochemical staining demonstrated a neuroendocrine differentiation of SmCC. No recurrence was observed during the 54-month follow-up period. We believe this to be the second case of SmCC with neuroendocrine differantiation of the parotid glands reported in Turkish medical literature and will be added to the english database as one of the favorable SmCC cases.

Comparative assessment of monopolar and bipolar radiofrequency surgery of inferior turbinate.

OBJECTIVE: The aim of this study was to compare early outcomes of monopolar (MP) and bipolar (BP) radiofrequency (RF) treatment of inferior turbinate hypertrophy from the perspective of both the patient and the surgeon. STUDY DESIGN: Prospective, randomized, single-blind study. MATERIALS AND METHODS: Seventy-one patients with inferior turbinate hypertrophy resistant to medical treatment. BP RF was used in 36 patients and MP RF in 35 patients, respectively. Patients received no other treatment during a 6-month follow-up. They were evaluated for symptoms such as nasal obstruction severity, nasal obstruction frequency, postnasal drip, nasal crusting, hyposmia, patient satisfaction, and preoperative pain with the use of a visual analogue scale (VAS) before surgery and then 1 and 7 days as well as 1, 3, and 6 months after surgery. RESULTS: No significant difference was observed regarding symptoms of patients after BP and MP inferior turbinate RF surgery in a long-term follow-up. Patients treated with MP RF showed early symptom improvement on days 1 and 7 days after surgery compared to the BP group. Procedure duration of MP RF was longer than that of BP RF. Pain during surgery was reported more frequently in the BP group. CONCLUSION: MP and BP RF treatment showed no difference in long-term efficacy. However, MP RF therapy was associated with early symptom improvement and less pain reported by patients in comparison to the BP RF group.

Metastatic follicular thyroid carcinoma masquerading as olfactory neuroblastoma: with skull-base, cranium, paranasal sinus, lung, and diffuse bone metastases.

Skull-base metastasis is rarely reported in thyroid carcinoma. We are presenting an unusual interesting case mimicking metastatic renal cell carcinoma with intense clear cell morphology, the thyroid origin of which was detected via positron emission tomography/computerized tomography scan proposed by the oncology council, while we were monitoring the subject with the initial diagnosis of paranasal sinus tumor. A mass was detected in the left nasal cavity in the endoscopic examination of the 68-year-old female patient referred by the ophthalmology clinic with the preliminary diagnosis of retro-orbital tumor upon being admitted with proptosis. A soft tissue lesion at a size of 68 × 39 × 53 mm located intracranially was detected by the brain computerized tomography. The biopsy taken and the immunohistochemical results were not satisfactory. Intense fluorodeoxyglucose involvement was observed in both lobes of the thyroid gland at positron emission tomography/computerized tomography taken with the recommendation of the council. Moreover, hypermetabolic nodules were seen in both lung parenchyma areas, whereas intense hypermetabolic lytic lesions were observed in the skeletal system. Thyroglobulin and thyroid transcription factor 1 stains displayed a strong staining on paraffin block. On the basis of these characteristics, the case was regarded as compatible metastatic follicular thyroid carcinoma, with skull-base, cranial, retro-orbital, paranasal sinus, lung, and bone metastases. This case showed us that multidisciplinary work and assessment of the oncology council play a highly critical role in making the diagnosis and guiding the treatment.

A Case of Cranial Meningioma with Symptoms Similar to Nasopharyngeal Mass.

Meningiomas are generally slow-growing benign tumors associated with the dura. They form lumps that mostly grow extra-axially, by repulsing, rather than infiltrating the surrounding neural parenchyma. Majority of meningiomas are intracranial. However, although rare, meningioma formation has been reported in almost all other organs. We report the case of a patient with an extra-neuraxial meningioma presenting as a nasopharyngeal mass.

Evaluation of Inner Ear Damage by Using Otoacoustic Emissions in Patients Who Underwent Mastoidectomy and Tympanoplasty Operations in the Early Period.

OBJECTIVE: We aim to demonstrate inner ear damage caused by drilling in the early period. Healthy contralateral ears of patients who underwent mastoidectomy using drill or tympanoplasty without using drill were compared. METHODS: A total of 38 patients (mastoidectomy: 22, tympanoplasty: 16) who were diagnosed as chronic otitis media and were scheduled for surgery were included. Distortion product (dp) otoacoustic emissions measurements were performed on healthy contralateral ears of patients on pre- and post-operative 1. hour, 1. day, 2. day, 3. day, and 4. day. RESULTS: In mastoidectomy group, dp otoacoustic emission values on post-operative 1. hour, 1. day, 2. day, 3. day, and 4. day at a frequency of 4000 Hz were significantly lower than in tympanoplasty group (p<0.05). In mastoidectomy group, dp values on post-operative 1. hour, 1. day, 2. day, 3. day, and 4. day at 4000 Hz significantly decreased in comparison with pre-operative period (p<0.05). In comparison with pre-operative period, decrease in dp values on post-operative 1. hour, 1. day, and 2. day at 4000 Hz in mastoidectomy group is significantly higher than those in tympanoplasty group (p<0.05). In tympanoplasty group, dp values on post-operative 1. hour at 4000 Hz significantly decreased in comparison with pre-operative period (p<0.05). CONCLUSION: Drilling used in mastoidectomy operation damage healthy contralateral ears by causing acoustic trauma. This damage can be determined by otoacoustic emissions in the early period. According to our study, hearing loss is temporary and more distinct at higher frequencies.

The analysis of the maxillary sinus volumes and the nasal septal deviation in patients with antrochoanal polyps.

The aim of this study was to evaluate the relationship between the maxillary sinus volumes and the nasal septal deviation angles in patients with antrochoanal polyps (ACP). 76 patients who underwent ACP surgery were included in the study. Of those 36 patients who had multislice computed tomography (MSCT) were evaluated to calculate maxillary sinus volume. The records of paranasal MSCT of 36 healthy people without any paranasal sinus diseases or surgery constituted age- and gender-matched healthy controls. Maxillary sinüs volumes and septal deviation angles were calculated using the paranasal MSCT volume-rendering technique. Thirty-six patients in the ACP group were compared with 36 polyp side-matched healthy people. The mean age was 16.6 ± 6.7 years in both groups. Statistically, the mean value of the maxillary sinus volume was significantly higher in the ACP group compared with the ACP side-matched control group (15.1 ± 4.6 versus 12.0 ± 3.5 mm(3)) (p = 0.002). Furthermore, the mean value of the maxillary sinus volume in the non-polyp side (14.2 ± 4.7 mm(3)) was statistically higher in the ACP group compared with the side-matched control group volume (11.9 ± 3.8 mm(3)) (p = 0.024). In addition, Fifty-three of 76 ACP patients had septal deviation. While the septal deviation was on the same side with the ACP in 17 patients, it was on the opposite side in 36 patients. In conclusion, the maxillary sinus volumes increased in ACP patients compared with the healthy control group. Many patients had nasal septal deviation on the opposite side of the ACP.

Medium-term results of combined treatment with transcranial magnetic stimulation and antidepressant drug for chronic tinnitus.

We compared the effects of repetitive transcranial magnetic stimulation (rTMS) and paroxetine [a selective serotonin reuptake inhibitor (SSRI)] on tinnitus in terms of effectiveness and medium-term results. This is a randomised, double-blind, placebo-controlled study. Seventy-five patients with moderate tinnitus were divided into five equal groups. Each group was treated for 1 month as follows: group 1 received rTMS alone at 1 Hz frequency; group 2 received rTMS alone at 10 Hz frequency; group 3 received rTMS at 1 Hz frequency combined with paroxetine; group 4 received paroxetine alone; and group 5 received a placebo (sham rTMS). Participants were tested using the Tinnitus Handicap Inventory (THI), Tinnitus Severity Index (TSI), the Beck Anxiety Scoring (BAS), and Psychiatric Sign Screening (PSS) tests. THI, TSI, BAS, and PSS were measured prior to treatment, and at the first and sixth month post-treatment. The THI and TSI scores improved after treatment in all groups, except the placebo group. The THI scores in groups 1 and 2 showed a statistically significant improvement after the first and sixth month compared to pretreatment scores, whereas a significant improvement in THI scores occurred only after the sixth month in groups 3 and 4. The TSI scores in group 3 showed a significant improvement at the first and sixth month marks after treatment. The rTMS and SSRI play potential roles in the reduction of tinnitus severity, but without cumulative or synergistic effects when a combination of treatment regimens is applied. These positive effects might be due to the relationship between the auditory cortex areas related to emotions and tinnitus.
