Corticosteroids in the Treatment of Vestibular Neuritis: A Systematic Review and Meta-Analysis

Objective: To systematically review and meta-analyze the results of all randomized controlled trials comparing corticosteroids with placebo for the treatment of patients with vestibular neuritis. Data Sources: An electronic search was performed in MEDLINE, EMBASE, Cochrane Library, and CENTRAL databases, and then extensive hand-searching was performed for the identification of relevant studies. No time and language limitations were applied. Study Selection: Prospective randomized controlled trials comparing corticosteroids with placebo for the treatment of patients with vestibular neuritis. Data Extraction: Odds ratios (ORs), weighted mean differences (WMD), 95% confidence intervals (CIs), and tests for heterogeneity were reported. Data Synthesis: Four studies were eventually identified and systematically reviewed. Meta-analysis was feasible for 3 studies. Regarding the recovery of clinical symptoms, the proportion of patients with clinical recovery at 1 month after the initiation of therapy did not differ significantly between the corticosteroids and placebo groups (OR, 1.45; 95% CI, 0.26-8.01; p = 0.67). The proportion of patients with caloric complete recovery was significantly different between the corticosteroids and placebo groups both at 1 (OR, 12.64; 95% CI, 2.6-61.52; p = 0.002; heterogeneity, p = 0.53; fixed effects model) and 12 months (OR, 3.35; 95% CI, 1.45-7.76; p = 0.005; heterogeneity, p = 0.03; random effects model) after the initiation of therapy. The caloric extent of canal paresis at 12 months after the initiation of therapy seemed to differ significantly between patients who received corticosteroids and those who received placebo (WMD, −12.15; 95% CI, −19.85 to −4.46; p < 0.05; heterogeneity, p < 0.05; random effects model). Conclusion: The present systematic review and meta-analysis, based on the currently available evidence, suggests that corticosteroids improve only the caloric extent and recovery of canal paresis of patients with vestibular neuritis. At present, clinical recovery does not seem be better in patients receiving corticosteroids.

PRIMARY LARYNGEAL LYMPHOMA: REPORT OF 3 CASES AND REVIEW OF THE LITERATURE

Extranodal lymphomas limited to the larynx are rare, accounting for less than 1% of all laryngeal neoplasms. The aim of this study was to report the experience of our department in the management of these aggressive lesions, as they require special diagnostic and therapeutic attention.

Primary pleomorphic adenoma of the external ear canal. Report of a case and literature review.

INTRODUCTION Primary neoplasms of the external ear canal are rare, and 5% of these tumors are of glandular origin. Ceruminal glands are modified sweat glands of the skin of the external auditory meatus that may give rise to (a) benign tumors such as ceruminous adenoma, pleomorphic adenoma, and syringocystadenoma papilliferum, and (b) malignant tumors such as ceruminous adenocarcinoma, adenoid cystic carcinoma, and mucoepidermoid carcinoma. An alternative theory holds that pleomorphic adenomas may well arise from ectopic salivary tissue present in the external ear canal. These tumors are very rare and usually have a benign course. In this report, we describe an unusual case of pleomorphic adenoma of the external auditory canal associated with chronic infection of the middle ear. CASE REPORT A 60-year-old woman presented with exacerbation of left otalgia over a 6-month period. She had been affected with chronic otitis media and aural polyps for the last 13 years, for which she had received medical treatment only. A canal-filling aural polyp was noted on clinical examination. Subsequent biopsy and histologic examination revealed pleomorphic adenoma of the external ear canal, possibly with malignant elements. Magnetic resonance imaging showed no intracranial extension or any association with the adjacent parotid gland. The patient underwent modified radical mastoidectomy and complete resection of the tumor and the entire skin of the external auditory canal. Final histology and immunohistochemistry confirmed the absence of malignancy, and no recurrence has been reported 1 year postoperatively. CONCLUSIONS Pleomorphic adenoma is an extremely rare tumor arising from the ceruminal glands of the external ear canal. Nonspecific presentation and difficult histologic diagnosis characterize this benign neoplasm. Wide local excision is the mainstay of treatment.

Olfactory dysfunction in nasal polyposis: correlation with computed tomography findings.

Aims: This study evaluates if a computed tomography (CT) scan is useful to assess the olfactory loss in sinonasal disease, and if a preoperative CT scan has a predictive value for the long-term outcome regarding olfaction. Methods: Thirty-one patients with nasal polyposis were included. Olfactory function was assessed with the ‘Sniffin’ Sticks’ test and subjective perception recorded with a visual analogue scale. CT scans were assessed with the Lund-Mackay system and the Damm nasal segmentation. Patients were retested after endoscopic sinus surgery in a follow-up appointment at least 1 year later. Results: Disease in the upper meatus and the posterior portion of the middle meatus strongly affects olfactory function. Lund-Mackay scores were significantly correlated with preoperative olfactory test results. Preoperative subjective ratings had a significant correlation only with present disease in the anterior upper meatus. Postoperative results were significantly decreased. Their relative percentage change was correlated only with the preoperative presence of disease in the anterior upper meatus. No correlation was found between the Lund-Mackay score and the postoperative olfactory results. Conclusions: Olfactory dysfunction in nasal polyposis is strongly related to specific obstructed nasal areas. A CT scan has no predictive value for the long-term surgical outcome regarding olfaction.

Speech perception and production in children with inner ear malformations after cochlear implantation.

OBJECTIVE The aim of this study was to assess the speech perception and speech intelligibility outcome after cochlear implantation in children with malformed inner ear and to compare them with a group of congenitally deaf children implantees without inner ear malformation. METHODS Six deaf children (five boys and one girl) with inner ear malformations who were implanted and followed in our clinic were included. These children were matched with six implanted children with normal cochlea for age at implantation and duration of cochlear implant use. All subjects were tested with the internationally used battery tests of listening progress profile (LiP), capacity of auditory performance (CAP), and speech intelligibility rating (SIR). A closed and open set word perception test adapted to the Modern Greek language was also used. In the dysplastic group, two children suffered from CHARGE syndrome, another two from mental retardation, and two children grew up in bilingual homes. RESULTS At least two years after switch-on, the dysplastic group scored mean LiP 62%, CAP 3.8, SIR 2.1, closed-set 61%, and open-set 49%. The children without inner ear dysplasia achieved significantly better scores, except for CAP which this difference was marginally statistically significant (p=0.009 for LiP, p=0.080 for CAP, p=0.041 for SIR, p=0.011 for closed-set, and p=0.006 for open-set tests). CONCLUSION All of the implanted children with malformed inner ear showed benefit of auditory perception and speech production. However, the children with inner ear malformation performed less well compared with the children without inner ear dysplasia. This was possibly due to the high proportion of disabilities detected in the dysplastic group, such as CHARGE syndrome and mental retardation. Bilingualism could also be considered as a factor which possibly affects the outcome of implanted children. Therefore, children with malformed inner ear should be preoperatively evaluated for cognitive and developmental delay. In this case, counseling for the parents is mandatory in order to explain the possible impact of the diagnosed disabilities on performance and habilitation.

Sensorineural hearing loss in children with thalassemia major in Northern Greece

Eighty eight (88) beta-thalassemic patients undergoing regular transfusion- chelation therapy with desferrioxamine (DFO) were studied for ENT problems from 1988 to 1993, as DFO has been implicated for auditory neurotoxicity. The mean age of the patients was 9.66 +/- 3.1 years, their pre-transfusion haemoglobin level was 9 +/- 2 g/dl, serum ferritin level was 2065 +/- 898 ng/ml and the daily DFO dose was 50.7 +/- 9.5 mg/kg for 5 days/week. The ENT study included, ENT examination, pure tone audiometry, speech audiometry, tympanometry, tone decay test and ABR. During this 6-year study 24/88 (27%) patients developed bilateral or ipsilateral sensorineural hearing loss in high tone frequencies, sometimes exceeding 80 dB, which was attributed to DFO toxicity. Therefore, a reduction or temporary withdrawal of DFO followed. After this intervention 12/24 patients recovered almost completely, 7/24 remained stable and 5/24 presented aggravation of their hearing loss. This study confirms the DFO induced auditory neurotoxicity and the necessity of periodical audiology control of beta-thalassemic patients for prompt diagnosis and management of this complication.

Sarcoidosis-like granulomatosis of the hypopharynx as a complication of anti-TNF therapy.

INTRODUCTION Sarcoidosis is a multisystem granulomatous disease of unknown etiology, occasionally presenting with signs and symptoms that occur within the head and neck. Recently, granulomatous reactions and cases of sarcoidosis have been reported in patients treated with anti-TNF agents. METHODS This report describes a 56-year-old man who developed sarcoidosis in the hypopharynx during adalimumab therapy for psoriatic arthritis. A retrospective review of the literature was performed using the PubMed database. RESULTS In our patient, a chronic granulomatous reaction consistent with sarcoidosis developed after 2 years of continuous treatment with adalimumab. The diagnosis of sarcoidosis was established by the typical well-formed non caseating granulomas on biopsy, after excluding all other granulomatous conditions. Following withdrawal of anti-TNF agents and a course of steroids, the clinical picture resolved. CONCLUSIONS The development of sarcoidosis during treatment with TNF-a antagonists represents a rare and paradoxical adverse event. To our knowledge this is the first case of sarcoidosis of the hypopharynx reported in the literature.

Cartilage-sparing otoplasty: Our experience

Prominent ears are the most frequent congenital deformity in the head and neck area. Otoplasty has undergone important developments and numerous techniques have been employed to address the anatomical defects, namely the lack of antihelix and the overdevelopment of the concha. We present a cartilage-sparing technique involving scapha--conchal sutures insertion to recreate the antihelix, conchal setback and cartilage weakening. No cartilage is excised. Prior to creating the antihelix, the medial surface of the cartilage is superficially scored. Occasionally a tangential excision of the posterior prominence of the cartilage prior to the placement of set back sutures is employed for an excessively large conchal bowl. A series of 86 consecutive patients underwent otoplasty with this technique. According to our experience the described technique gives good and predictable long-term results with a natural-appearing ear. Significant complications are rare. In case of loss of correction, revisional surgery is straightforward on the intact pinna cartilage.

Influence of the turbinate volumes as measured by magnetic resonance imaging on nasal air conditioning.

Background Changes in nasal airflow caused by varying intranasal volumes and cross-sectional areas affect the contact between air and surrounding mucosa entailing alterations in nasal air conditioning. This study evaluates the correlation between nasal air conditioning and the volumes of the inferior and middle turbinates as measured by magnetic resonance imaging (MRI). Methods Fourteen healthy volunteers were enrolled. Each volunteer had been examined by rhinomanometry, acoustic rhinometry, intranasal air temperature, and humidity measurements at defined intranasal sites as well as MRI of the nasal cavity and the paranasal sinuses. The volumetric data of the turbinates was based on the volumetric software Amira. Results Comparable results were obtained regarding absolute humidity values and temperature values within the nasal valve area and middle turbinate area for both the right and the left side of the nasal cavity. No statistically significant differences were found in the rhinomanometric values and the acoustic rhinometry results of both sides (p > 0.05). No statistical correlations were found between the volumes of the inferior (mean, 6.1 cm3) and middle turbinate (mean, 1.8 cm3) and the corresponding humidity and temperature values. Additionally, the air temperature and humidity values did not correlate with the rhinometrical endonasal volumes (0–20 mm and 20–50 mm from the nasal entrance). Conclusion The normal range of volumes of the inferior and middle turbinate does not seem to have a significant impact on intranasal air conditioning in healthy subjects. The exact limits where alterations of the turbinate volume negatively affect nasal air conditioning are still unknown.

Hybrid Carcinoma of the Larynx: A Case Report (Adenoid Cystic and Adenocarcinoma) and Review of the Literature

Introduction. The nonsquamous carcinomas of the larynx are considered rare with the majority of malignant tumors in this area, reaching the rate of 95%, to be squamous cell neoplasms. Case Report. The case refers to a 53-year-old man that presented with symptomatology of motor nerve disease. During the evaluation of the neurologic disease, a subglottic mass of the larynx was revealed accidentally in the imaging examination. Under general anesthesia, we performed direct laryngoscopy and biopsy of the mass. The histopathologic examination revealed a hybrid carcinoma coexistence of two different carcinomas, an adenoid cystic carcinoma and an adenocarcinoma, not otherwise specified with poor differentiation. Regarding the therapeutic plan, the mass was considered inoperable due to its expansion to trachea and the patient received radiotherapy. Conclusions. Both the adenocarcinoma and adenoid cystic carcinoma are extremely rare types of malignant tumors in the larynx. The special interest of the present case is the coexistence of these two rare tumors in the same region of the larynx, being a hybrid tumor of the salivary glands in the larynx, which is the second reported case, based on our systematic literature review.
