Tympanoplasty in pediatric patients.

OBJECTIVE: The aim of this study is to analyze the clinical features and follow-up of a series of pediatric patients with chronic otitis media undergoing tymponaplasty surgery and to identify the effect of the factors on the course. METHODS: Forty-one children (mean age 15.1+/-2.62 years, range from 8 to 16 years) who had undergone tympanoplasty with or without ossicular reconstruction were evaluated. Age, gender, size and site of perforation, status of operated ear (dry/discharging), status of the contralateral ear, underlying cause of the perforations, surgical technique, preoperative and postoperative hearing levels, average postoperative follow-up time, and postoperative complications were recorded. RESULTS: Myringoplasty in 28 patients (68.3%), incus interposition in 7 patients (17.1%), partial ossicular replacement prostheses in 4 patients (9.7%) and total ossicular replacement prostheses in 2 patients (4.9%) were performed. In the 37 (90.2%) of patients, intact graft was determined during postoperative follow-up. Surgical success including intact graft and postoperative air-bone gap of less than 25 dB were obtained in 34 (82.9%) cases. CONCLUSIONS: The present study suggested that tympanoplasty was a quite successful method in the appropriate pediatric patients between the ages of 8 and 16 years. In the preoperative evaluation for surgery success, some factors, such as dry middle ear, healthy contralateral ear and concordant to postoperative care should be considered.

Anterior atticoantrostomy for cholesteatoma surgery.

OBJECTIVES: We aimed to investigate the long-term results of anterior atticoantrostomy in adult patients with cholesteatoma. METHODS: A total of 83 ears in 78 patients were operated on by the anterior atticoantrostomy technique, supported by a periosteal flap, between 1991 and 2002. RESULTS: Cholesteatoma recurred in only 4 ears (4.8%). In the 79 ears without recurrence, re-perforation was observed in 3 ears (3.8%), and retraction pockets developed in the attic of 5 ears (6.3%), 2 of which needed ventilation tubes. Absorption or migration of cartilage grafts was not seen in any of the patients. The mean air-bone gap was 34.8 +/- 13.4 dB and 16.9 +/- 14.7 dB, and the mean high-tone bone conduction was 19.0 +/- 6.2 dB and 21.1 +/- 6.6 dB, in the preoperative and postoperative periods, respectively. CONCLUSIONS: In the reconstruction of the posterior canal wall, a cartilage graft supported by a periosteal flap prevents attic retraction and may increase the vascularization of the graft. After anterior atticoantrostomy, the recurrence rate and the probability of leaving residual tissue are low. Therefore, we believe that anterior atticoantrostomy is a relatively safe and effective technique that can be used in the management of cholesteatoma.

[Foley balloon placement for maxillofacial fractures].

OBJECTIVES: The aim of the study was to evaluate the effectiveness of maxillary sinus Foley balloon placement in patients with maxillofacial fractures. PATIENTS AND METHODS: This study included 38 patients (10 females, 28 males; mean age 29.1+/-11.6; range 9 to 49 years) in whom Foley balloon placement and gauze packing were performed for blow-out, orbitozygomatic, or maxillary fractures. Sex and age distributions, etiology of trauma, localization of fractures, management, intraoperative and postoperative complications were evaluated. RESULTS: Eighteen patients had blow-out fractures, 15 patients had orbitozygomatic fractures, and five patients had Le Fort II-III fractures of the maxilla. Preoperatively, enophthalmos, diplopia, limited ocular motility, and facial asymmetry were found in 28.9%, 26.3%,18.4% and 65.8%, respectively. Sufficient maxillary sinus patency was obtained in 32 patients (84.2%). Enophthalmos, diplopia, limited ocular motility, and facial asymmetry were found in 13.2%, 7.9%, 5.3%, and 18.4% in the postoperative period, respectively. CONCLUSION: Maxillary Foley balloon placement should be preferred in the blow-out, orbitozygomatic, and maxillary fractures because it supports the orbital floor and provides sufficient maxillary sinus patency.

[Treatment options and common problems in patients with maxillofacial trauma].

BACKGROUND: The approach and type of management along with the common complications in maxillofacial trauma were evaluated in this study. METHODS: Medical records of 602 patients (486 males; 116 females; mean age 28,4+/-15,2; range 1 to 80 years) with maxillofacial fractures, admitted to the Department of Otolaryngology between 1992 and 2004, were evaluated in this study. Maxillofacial fracture was diagnosed by clinical and radiological findings. Sex and age distribution of patients, etiology of trauma, localization of the fractures, treatment modalities, time to treatment after the trauma and postoperative complications were recorded. RESULTS: There were 257 (42,7%) mandible, 156 (25,9%) nose, 66 (11%) maxillary, 34 (5,6%) zygoma, 32 (5,3%) multiple facial, 29 (4,8%) blow-out and 28 (4,7%) frontal sinus fractures. While 256 (43%) patients underwent closed reduction, 346 (57%) patients were treated by open reduction. Postoperative complications were seen in 8,3% (51) of patients. CONCLUSION: Although associated with some complications, open reduction and miniplate fixation should be the preferred treatment option, since it provides a powerful fixation, is easy to perform, and has better esthetic and cosmetic results.

[Petrous bone lesions].

OBJECTIVES: We evaluated the results of treatment and follow-up of patients with petrous bone lesions. PATIENTS AND METHODS: We retrospectively evaluated 13 patients (5 females, 8 males; mean age 33.8+/-17.4 years; range 4.5 to 65 years) who were treated and followed-up for petrous bone lesions between 1990 and 2004. The diagnoses were cholesterol granuloma (n=2; 15.4%), chondrosarcoma (n=1; 7.7%), and cholesteatoma (n=10; 76.9%). RESULTS: Patients with cholesterol granuloma had complaints of cephalgia and diplopia while those with cholesteatoma complained of otorrhea and hearing loss. One patient with cholesterol granuloma and eight patients with cholesteatoma underwent surgical operations with the use of middle skull base approach (n=1), transcochlear approach (n=2), translabyrinthine approach (n=1), and tympanopetrosectomy (n=5). Two cases with congenital cholesteatoma and one patient with cholesterol granuloma refused surgical intervention and were only followed-up. CONCLUSION: Besides surgical intervention, follow-up by computed tomography or magnetic resonance imaging may be considered in patients with incidental petrous bone lesions, presenting with limited symptoms.

Postauricular subcutaneous leiomyosarcoma.

Superficial leiomyosarcomas are rare soft tissue tumors, most frequently involving the lower extremity. Leiomyosarcomas which could be misdiagnosis or delayed are very rare in the head and neck region. In this report, a 46-year-old man with postauricular leiomyosarcoma was presented. The tumor was totally excised with 3 cm margins. Immunohistochemically, the specimen showed reactivity for smooth muscle actin, vimentin, and desmin. No complications developed in the postoperative period and the patient was free of recurrence at the 26 months follow-up. Immunohistopathological examination is essential for an accurate histological diagnosis. The ENT surgeon should pay attention to superficial leiomyosarcoma with its specific behavior and treatment while evaluating the lesions in the head and neck region.

Micronucleus frequency in acquired middle ear cholesteatoma.

OBJECTIVE: To determine the micronucleus (MN) frequency of acquired cholesteatoma tissue using an MN assay. MATERIAL AND METHODS: Eighteen patients were diagnosed as having chronic otitis media with acquired cholesteatoma and were divided into primary and secondary acquired cholesteatoma groups. Cholesteatoma tissue and normal tissue specimens from the external ear canal skin were taken from the patients during surgical operations. MN frequencies of cholesteatoma and control samples were determined according to standard criteria. RESULTS: The MN frequencies of the cholesteatoma and control tissues were 0.54%+/-0.31% and 0.24%+/-0.11%, respectively (p<0.01). MN frequencies for the primary and secondary acquired cholesteatoma groups were 0.63%+/-0.36% and 0.46%+/-0.26%, respectively (p>0.05). MN frequencies in cholesteatoma patients without and with complications were 0.42%+/-0.19% and 0.85%+/-0.37%, respectively (p<0.05). CONCLUSION: MN frequencies were found to be increased in cholesteatoma tissues when compared with external ear canal skin. The MN frequency in five cases with complications was higher than in cases without complications. These results indicate that there could be associations between MN frequency and acquired cholesteatoma and between MN frequency and complications.

Pharyngeal reflux in children with chronic otitis media with effusion.

OBJECTIVE: To investigate whether there is an association between chronic otitis media (COM) with effusion and pharyngeal reflux in children by using 24-h pH monitoring with a dual probe. MATERIAL AND METHODS: This was a prospective study. The study group consisted of 25 children with COM with effusion and the control group comprised 12 healthy children. All children underwent 24-h esophageal pH monitoring with a dual probe (distal and proximal esophageal pH monitoring). RESULTS: In the study group, the frequencies of pharyngeal and gastroesophageal reflux (GER) were 48% and 64%, respectively, and the corresponding values in the control group were 8.3% and 25%. Both of these differences were significant (p <0.05). In the study group, 28% of patients were positive for at least 1 symptom of GER; 72% of the patients did not have any symptoms but 56% of these patients had silent GER. CONCLUSIONS: These findings indicate that pharyngeal reflux may play an important role in the etiology of COM with effusion. If patients have typical symptoms of GER, such as pyrosis, regurgitation, dysphagia and emesis, the presence of GER should be considered. The presence of silent GER and pharyngeal reflux should also be considered.

Analysis of chromosomes 8 and 17 aneuploidies in laryngeal squamous cell carcinoma by fluorescence in situ hybridization.

OBJECTIVES/HYPOTHESIS: The objectives were to investigate chromosomes 8 and 17 numerical aberrations by using fluorescence in situ hybridization in laryngeal squamous cell carcinoma and also to determine whether there is any association between chromosomes 8 and 17 aneuploidies and TNM classification and subgroups of laryngeal squamous cell carcinomas. STUDY DESIGN: Descriptive study. METHODS: Tumor and control samples were taken from 23 patients with LSCC by surgical operation. Fluorescence in situ hybridization analysis with chromosomes 8- and 17-specific alpha-satellite DNA probes was performed on the interphase nuclei. RESULTS: The percentages for chromosomes 8 and 17 aneuploidies were 33% (SD = 25.7%) (median value, 26.2%; range, 3.5%-81.8%) and 19.2% (SD = 15.8%) (median value, 9.8%; range, 3.6%-63.7%), respectively. There was a significant difference between stage 2 and stage 3 (P <.05) and between stage 2 and stage 4 for chromosome 8 aneuploidy (P <.05) but not for chromosome 17 aneuploidy (P >.05). There was also a significant difference for the T classification for chromosome 8 aneuploidy (P <.05) but not for chromosome 17 (P >.05). CONCLUSION: Chromosome 8 aneuploidy may be related to stage and T classification of laryngeal squamous cell carcinoma and its progression.
