RESUMO
Multiple techniques and a variety of materials used for grafting have been described and applied over the years. Silicone implants are one of the most widely used alloplastic materials in Asian rhinoplasty, however, there are several complications. The authors report a case of an Asian woman who presented with implant rejection after 25 years later as a late complication of rhinoplasty. The patient was underwent revision augmentation rhinoplasty and stayed uneventful for 6 months as she was satisfied with aesthetic results and nasal airflow. The silicone implants are still going to be the most popular grafts in Asian augmentation rhinoplasty even so the long term complications must be kept in mind.

OBJECTIVE: To research the ototoxicity of xylitol after intratympanic injection in mice ear model. METHODS: 24 female mice Balb/c mice (48 ears) included in the study. The mice were divided into 4 groups as 6 mice were found (12 ears) in each group. Solutions of 0.9% NaCl solution (Group A), 155â¯mg/ml (Group B), 310â¯mg/ml (Group C) and 620â¯mg/ml (Group D) xylitol, were applied into the middle ear cavity. Microscopic ear examination and auditory brainstem response test were done for each mouse before application of xylitol and on the 1st, 3rd and 10th day of injection. RESULTS: There are some statistically significant alterations found in the threshold values at 8000, 12000, 16000, 24000â¯Hz frequencies when each group were compared in itself on day 0, 1,3 and 10, which were independent from the increasing dosage. CONCLUSION: According to our findings intratympanic xylitol injection does not have any ototoxic effect in the inner ear. To evaluate the effects of xylitol more clinical studies are need to carried out.

INTRODUCTION: PFAPA (periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis) is the most frequent non-infectious cause of high fever observed among the European child population. While its cause is still not yet fully identified, PFAPA patients were previously shown to have altered tonsillar microbiome composition. Our study hypothesized that this is associated with a change in antimicrobial peptide (AMP) expression levels, as in the case of Crohn's disease which is another autoinflammatory disorder. METHODS AND MATERIALS: The tonsil specimens were isolated from seven patients with PFAPA syndrome, and six patients with group A beta-hemolytic streptococcal (GAßHS) recurrent tonsillitis. Tonsillar expression levels of human beta-defensin 1-2, cathelicidin, ribonuclease-7, and liver expressed antimicrobial peptide-1 were monitored by immunohistochemistry (IHC). Expression levels were scored using semi-quantitative analysis method and were statistically analyzed by Two-Way Repeated Measures Analysis of Variance test. RESULTS: Our results showed no significant difference in AMP expression levels between PFAPA and GAßHS patients. Immunolocalization of human beta-defensin 1 was different between the two groups; expressed at higher levels on tonsil surface epithelium (SE) than lymphoid interior (LI) in PFAPA patient group, while this was not evident in GAßHS patients group. CONCLUSIONS: Our results suggest that, PFAPA patients may be associated with altered AMP expression as in other autoinflammatory diseases. Future studies with subjects without any inflammatory condition are required for more precise conclusions.

OBJECTIVE: To compare hearing results in idiopathic sudden hearing loss patients treated with systemic steroids alone or combined intratympanic and steroids. STUDY DESIGN: Prospective. SETTING: Tertiary referral hospital. PATIENTS: Idiopathic sudden sensorineural hearing loss patients. INTERVENTIONS: The patients in the systemic therapy group received consecutive administration of 100 mg intravenous methylprednisolone in the first day, 80 mg/day oral prednisolone in 3 divided doses for the next 2 days, and continued with oral administration of steroids by tapering the dose 20 mg in every 2 days. The patients in the combined treatment group received intratympanic injection of methylprednisolone (an approximate dose of 0.5 ml of 125 mg/ml). A total of 5 injections on alternate days were performed. MAIN OUTCOME MEASURES: The mean and median PTA gains of systemic corticosteroid therapy (SCT) group were 7.5 and 5 dB at 5th day, 12.1 and 7.5 dB at 10th day, and 13.0 and 8.8 dB at 15th day. The mean and median PTA gains for combined treatment (CT) group were 12.5 and 7.5, 17.8 and 13.8, 21.8 and 20.0 dB, respectively. RESULTS: Both the mean and the median PTA gains were statistically significantly different between SCT and CT groups. According to improved hearing results (more than 10 dB gain), there was statistically significant difference between SCT and CT groups. None of the patients had an important complication. CONCLUSION: The results of this study suggest that adding intratympanic methylprednisolone to systemic therapy increases the probability of hearing recovery in ISSHL patients.

Necrotizing fasciitis (NF) is a potentially fatal soft-tissue infection characterized by rapidly progressive necrosis of subcutaneous tissue and superficial fascia. NF of the head and neck is a rare clinical entity, and it must be carefully differentiated from less severe conditions. Factors such as delayed treatment, inappropriate treatment, host debilitation, and polymicrobial infection contribute to the mortality and morbidity of NF. Adequate surgical debridement, urgent antibiotic therapy, and supportive measures are the keys to decreasing mortality and morbidity. We report 2 new cases and review the literature.

OBJECTIVES: Internal jugular vein (IJV) thrombosis is a rare complication of functional and selective neck dissections. It increases morbidity and may seldom be fatal. We investigated the frequency of IJV thrombosis and its relationship with the dissection technique. PATIENTS AND METHODS: We evaluated 52 functional and selective neck dissections performed in 34 male patients (mean age 57 years; range 34 to 76 years) with head and neck cancer. Dissections were mainly performed by sharp dissection (n=27) or cautery (n=25). The patients were examined by Doppler ultrasonography with respect to IJV flow and thrombosis preoperatively, and at two weeks and at 3 to 6 months postoperatively. RESULTS: In the early postoperative period, thrombosis was observed in 7.4% (n=2) of the necks treated with sharp dissection and in 4% (n=1) of the necks treated with cautery. There was no statistically significant difference between the two groups with respect to IJV thrombosis. Late Doppler examinations showed complete recanalization of all thrombosed IJVs. CONCLUSION: Our data suggest that sharp dissection or cautery techniques performed in functional neck dissections do not differ with respect to the frequency of postoperative IJV thrombosis.

OBJECTIVE: Corticosteroids are commonly used for the treatment of sudden sensorineural hearing loss (SSHL). In this study, the effectiveness of intratympanic (IT) corticosteroid injection was studied and compared with a control group on patients with SSHL who failed systemic corticosteroid treatment. MATERIALS AND METHODS: A total of 19 patients as a retreatment group (RG) and 18 patients as a control group (CG), all failed high-dose intravenous and oral corticosteroid treatments, were included in this study. These patients were invited back, and IT methylprednisolone was injected five times via 3-day intervals in RG and followed-up for a mean period of 24.9 months (range, 7-30 mo). Audiological evaluations were performed initially, a week after the completion of the injections, monthly in the following first 3 months, and at the end of follow-up period in RG. The CG was followed-up for 3 months after the completion of systemic corticosteroid treatment without any additional drug administration. RESULTS: The mean age was 52.6 years (range, 20-79 yr) in RG and 59.9 years in CG. The mean pure-tone average for speech frequencies (500-4,000 Hz) at baseline audiogram and at the first month, at the third month, and at last controls were 65.2 (range, 43-102 dB), 45.4 (range, 23-77 dB), 43.6 (range, 30-77 dB), and 44.5 (range, 33-77 dB) dB, respectively, in RG. The mean pure-tone averages for speech frequencies (500-4,000 Hz) at the end of systemic treatment and at third-month control were 63.5 (range, 44-98 dB) and 59.0 (range, 40-100 dB) dB, respectively, in CG. The hearing gain that is equal to or more than 10 dB was achieved in 14 patients (73.6%) at the last control in RG. No hearing gain could be detected in the CG. No serious side effect was observed with IT treatment. CONCLUSION: We conclude that IT methylprednisolone injection provides more significant hearing improvement for patients that failed with previous high-dose systemic corticosteroid administration than systemic corticosteroid treatment alone. So it may be the first-step medical treatment of idiopathic SSHL alone or at least may be combined with the systemic corticosteroid administration.

Laryngeal amyloidosis is rare, accounting for less than 1% of all benign laryngeal tumors. Although familial primary localized amyloidosis has been reported in other parts of the body, no familial cases have been reported in the larynx. Primary localized laryngeal amyloidosis was detected in two sisters whose ages were 35 years and 38 years, respectively. In the elder patient, a previous endolaryngeal biopsy for symptoms of dysphonia yielded no pathologic findings. Laryngoscopic examination of the patient showed a significant submucosal accumulation at the level of ventricles and vocal folds. The younger sister had a complaint of hoarseness for five years. The results of endolaryngeal biopsies performed in both patients were reported as amyloidosis. Further evaluations were negative for systemic amyloidosis. No surgical intervention was considered. The patients were monitored for more than two years without any other coexisting disease.

OBJECTIVE: To obtain objective acoustic analysis results from Parkinson's disease patients who do not have voice symptoms and to compare these results with those from age- and sex-matched control subjects. DESIGN: Prospective. SETTING: Tertiary reference hospital. METHOD: The objective acoustic analysis results from 14 female Parkinson's disease patients with no voice symptoms were compared with those of 22 age- and sex-matched normal subjects. RESULTS: Statistical analysis revealed no differences in mean fundamental frequency and shimmer values. However, differences in jitter values, loudness, and the harmonics to noise ratio were statistically significant between the two groups (p < .05). CONCLUSION: With this study, it was shown that Parkinson's disease patients who do not have any voice symptoms have objectively different acoustic values than their age- and sex-matched controls. Clinicians must be aware of these initial findings on the voice changes of Parkinson's disease patients.

Carpenter syndrome (Acrocephalopolysyndactyly type II), first described in 1901, consists of acrocephaly, syndactyly, polydactyly, congenital heart disease, mental retardation, hypogenitalism, cryptorchidism, obesity, umbilical hernia and bony abnormalities. We report a 6 years old boy presenting as a union of these malformations and also having bilateral sensorineural hearing loss. Auditory disturbances are not common among Carpenter syndrome patients. According to our knowledge, this is the first Carpenter syndrome case whose hearing loss is demonstrated by auditory brainstem response (ABR) test.

AIMS AND BACKGROUND: To delineate the lymphatic drainage in head and neck squamous cell carcinoma (SCC) patients by lymphoscintigraphy and to investigate whether the results of histopathological evaluation of sentinel nodes have any diagnostic relevance with regard to the metastatic involvement of all cervical lymph nodes. METHODS: Forty-one patients clinically pre-diagnosed as having primary head and neck SCC underwent Tc-99m nanocolloid lymphoscintigraphy and were evaluated according to the Memorial Sloan Kettering cervical lymph nodes level system. Treatment of 24 of these patients included neck dissection in addition to surgery for the primary tumor. RESULTS: Among the 24 operated patients nine were found to be pathologically N+. In two (22%) of these nine patients there were histopathological metastases in non-sentinel lymph nodes. In one patient with a metastatic lymph node, no sentinel nodes were identified. Altogether, lymphoscintigraphic sentinel node detection failed in three (33%) cases. CONCLUSION: The procedure of lymphoscintigraphic imaging of sentinel lymph nodes and its use in the determination of squamous cell carcinoma metastases is theoretically promising. However, in order to assess the true value of sentinel lymph node imaging and make treatment plans based on this technique, it's necessary to increase the number of cases included in the studies, and obtain results that are specific for the primary tumor and involved lymph nodes.

OBJECTIVE: The objective was to investigate the presence of Helicobacter pylori with polymerase chain reaction in the sinonasal mucosa of patients with or without chronic rhinosinusitis (CRS). STUDY DESIGN: A prospective clinical trial. METHODS: Mucosal tissue samples were collected from ethmoid cells of 12 patients with CRS and the removed mucosal part of the middle concha of 13 patients with concha bullosa who were treated surgically in our institution. DNA extracted from these samples was used for the amplification of 16S ribosomal RNA gene of H pylori by nested polymerase chain reaction. RESULTS: Helicobacter pylori DNA was detected in 4 of 12 patients with CRS, but it was not detected in patients with concha bullosa. Three of four patients with positive results for H pylori had gastroesophageal reflux-related complaints. CONCLUSIONS: It is possible to detect H pylori in the sinus mucosa of some patients with CRS. However, whether H pylori is a causative agent for CRS or a result of CRS is not known.
