Cavernous haemangioma of the external auditory canal: clinical case and review of the literature.

Although benign vascular lesions are frequent in the head and the neck region, clinical evidence of cavernous haemangioma of the external auditory canal is extremely rare; when present, the lesion invades the middle ear space. Herein, a rare case of a soft mass filling the external auditory canal, not involving the tympanic membrane, in a symptomatic 59-year-old male is described. Clinical and audiological characteristics, imaging studies and surgical treatment with histological evaluation are reported, which led to a diagnosis of a cavernous haemangioma. This is only the seventh case described in the literature, to date, not involving the tympanic membrane and the middle ear space. In addition, a review has been made of the relevant literature with respect to epidemiology, presentation, evaluation, pathology, and management options for haemangiomas arising in the external auditory canal.

Risk factors for otitis media with effusion: case-control study in Sicilian schoolchildren.

OBJECTIVE: To identify the prevalence and demographic, maternal and child risk factors for otitis media with effusion (OME) in Sicilian schoolchildren and analyse the results with reference to the review of the literature. METHODS: Associations of possible risk factors with prevalence of otitis media with effusion (OME) were studied in a cohort of 2097 children, aged 5-14 years. In order to determine OME, otoscopy and tympanometry were performed at 3-monthly intervals beginning at term date. Sixteen epidemiologically relevant features were inventoried by means of standardized questionnaires and skin tests were performed. Univariate analysis was performed to examine the association between determinants and occurrence of OME; multivariate logistic regression analysis was made to investigate the joint effect of atopy and other determinants on OME. RESULTS: Prevalence of OME resulted 6.8% (143/2097) and it was most strongly associated with atopy (P<0.0001; or=12.67; 95% CI=8.78-18.27). Other factors significantly associated with the prevalence of OME were snoring (P<0.0001), previous history of acute otitis media (P<0.001) and of recurrent URTIs (P<0.0001), mother's no schooling (P=0.01) and no breastfeed (P=0.05). No significance was found for school type, economic status of the family, family size, family history of presence of allergy and of ear disease, mother's work status, smoking parents and birth history. Moreover on multivariate logistic regression analysis it resulted that age, positive URTI's history and smoking exposure were found to be significant (P<0.0001). CONCLUSIONS: OME during infancy is a common and multifactorial disease; as most of the risk factors associated with its etiology and pathogenesis, are modifiable, their modification should represent the reasonable primary care intervention leading to a decrease in OME prevalence.

The role of atopy in otitis media with effusion among primary school children: audiological investigation.

The objective of this study was to evaluate the role of atopy in otitis media with effusion (OME) in children attending primary school in western Sicily focusing on the audiological characteristics among atopic and non-atopic subjects suffering from OME. A total of 310 children (5-6 years old) were screened by skin tests and divided into atopics (G1) and non-atopics (G2). The samples were evaluated for OME by pneumatic otoscopy, tympanogram and acoustic reflex tests. The parameters considered were: documented persistent middle ear effusion by otoscopic examination for a minimum of 3 months; presence of B or C tympanogram; absence of ipsilateral acoustic reflex and a conductive hearing loss greater than 25 dB at any one of the frequencies from 250 Hz through 4 kHz. A total of 56 children (18.06%) resulted to be atopics while 254 were non-atopics. OME was identified in 24 atopic children and in 16 non-atopic children for a total number of 40 children; the overall prevalence rate was 12.9% (42.85% for G1 and 6.30% for G2). OME was bilateral in 28 children (70%), with a significative difference between G1 (79.17%) and G2 (56.25%). The prevalence of B tympanogram was 70.59%, corresponding to 79.07% for G1 and 56% for G2. The mean air conduction pure tone was, respectively, 31.97 dB for G1 and 29.8 dB for G2. The prevalence value of OME in atopic children, also supported by the higher predominance of bilaterality, B tympanogram and hearing loss among this group, could suggest the important role of allergy in the pathogenesis of OME.
