Tympanometric Patterns of Children with Allergic Rhinitis Treated at a Tertiary Health Institution

Risk Factors for Otitis Media with Effusion in Preschool and School Children in Calabar Municipality

BACKGROUND

Predisposing factors for otitis media with effusion are multifactorial, ranging from genetic and anatomical abnormalities to environmental factors and inflammation of the nose and adjacent structures.

AIM

The study determined the risk factors for otitis media with effusion (OME) among children in Calabar Municipality.

METHODS

This was a descriptive, cross-sectional, community-based study including children aged 1-10 years randomly selected from government and privately owned daycares, nurseries (preschool), and primary schools. The risk factors assessed included upper respiratory tract infection, allergic rhinitis, adenoid enlargement, acute otitis media, recurrent acute otitis media parental educational level, overcrowding (four children sleeping in a room), duration of breastfeeding, cleft palate, and Down's syndrome. Allergic rhinitis was diagnosed when a child had at least two of the rhinological symptoms: nasal congestion, running nose, sneezing, itching of the eye or nose, and at least one of the following: history of allergy, family history of allergy, and positive history of asthma. The questionnaire was the research instrument used to assess the risk factors for OME. OME diagnosis was made with otoscopy and tympanometry. Data were collected and analyzed with IBM SPSS version 25, and a P value <0.05 was considered statistically significant.

RESULTS

A total of 24 daycare pupils, 141 nursery pupils, and 155 primary pupils were recruited into the study. The prevalence of otitis media with effusion was more in younger children than in older children and the relationship was statistically significant (P < 0.001). Female children were more statistically affected than male children (P = 0.007). Children with allergic rhinitis accounted for a higher proportion of those with OME than those without allergic rhinitis (26.7% vs. 11.6%), and the difference was statistically significant (P = 0.007). The association between OME and upper respiratory tract infection, acute otitis media, and recurrent acute otitis media was not statistically significant (P > 0.05). Multivariate binary logistic regression was used to identify predictors for the otitis media with effusion.

CONCLUSION

There are many endogenous and exogenous risk factors for OME, but notable risk factors in our study were age 1-2 years, female sex, and allergic rhinitis.

The role of allergic and nonallergic rhinitis on success of type 1 cartilage tympanoplasty

OBJECTIVE

To investigate the role of allergic rhinitis (AR) and non-allergic rhinitis (NAR) on success of type 1 cartilage tympanoplasty.

METHODS

This prospective study was conducted on 60 patients who had type 1 cartilage tympanoplasty. The patients were divided into three groups as no-rhinitis (n = 28), NAR (n = 18) and AR (n = 14) groups, based on their symptoms, skin prick tests and/or serum specific IgE levels. AR and NAR groups were treated for their rhinitis symptoms both pre- and postoperatively. The patients were followed up for a minimum of 6 months and compared for graft success rates and audiological outcomes.

RESULTS

Three study groups were similar for age, gender distributions and preoperative air-bone gaps (p = 0.780, p = 0.167 and p = 0.676, respectively). Postoperative graft perforation rate was 0% in no-rhinitis and AR groups while it was 16.7% in NAR group, with a significant difference among three groups (p = 0.034). The comparison of three study groups for change in the postoperative air bone gaps in comparison with preoperative air bone gaps did not yield any statistically significant result (p = 0.729).

CONCLUSION

Although AR does not result in failure of type 1 cartilage tympanoplasty in patients treated for rhinitis compared to the control group, NAR does. Pre- and postoperative treatment of patients for rhinitis and employment of cartilage graft may be the key factors for success of surgery in patients with AR. Further studies with a larger sample size are needed.

Comparative study on adhesive otitis media and pars tensa cholesteatoma in children

OBJECTIVE

Recurrent otitis media and persistent otitis media with effusion in early childhood may cause an atelectatic eardrum and adhesive otitis media, which sometimes progress to pars tensa cholesteatoma. When and how children with adhesive otitis media should be operated on remain controversial. Therefore, this study aimed to analyze the clinical characteristics of children with adhesive otitis media and pars tensa cholesteatoma, and to determine the risk factors of progression to cholesteatoma.

METHODS

Seventeen ears of 15 children with adhesive otitis media (adhesive group) and 14 ears of 13 children with pars tensa cholesteatoma (tensa cholesteatoma group) who underwent tympanoplasty were included in this study. We analyzed the following clinical characteristics of children in both groups: medical and life history, associated diseases, sites of the adhesion, and development and aeration of mastoid air cells as shown by temporal bone computed tomography.

RESULTS

Most of the children in both groups had a history of recurrent otitis media and/or persistent otitis media with effusion. They showed a male predominance and a frequent association of allergic rhinitis. The number of ears showing undeveloped mastoid air cells in the tensa cholesteatoma group was significantly larger than that in the adhesive otitis media group (P=0.0068). A lack of aeration of the middle ear, including the eustachian tube, was more frequently found in ears with pars tensa cholesteatoma than in ears with adhesive otitis media (P=0.0012). Using multivariate logistic regression, the presence of otorrhea (odds ratio [OR], 14.847; 95% confidence interval [CI], 0.834-264.184), total adhesion (OR, 28.550; 95% CI, 0.962-847.508), and undeveloped mastoid air cells (OR, 19.357; 95% CI, 1.022-366.589) were related to pars tensa cholesteatoma.

CONCLUSION

Children with adhesive otitis media should be carefully followed up in the outpatient setting. Ears with poor mastoid development may develop pars tensa cholesteatoma. Additionally, ears with middle ear effusion, total adhesion, and the presence of otorrhea tend to be at risk of pars tensa cholesteatoma. Tympanoplasty or tympanostomy tube insertion should be considered for children with adhesive otitis media who have these risk factors to prevent progression to pars tensa cholesteatoma.
