Is it Merely Mischief or a Sign? Children with a Foreign Body in the External Acoustic Meatus.
Serous otitis media (SOM) is the existence of fluid in the middle ear without middle ear mucosal inflammation. SOM may occur as a spontaneous inflammatory response owing to poor tubal function in the presence of sinonasal disease or after acute otitis media, typically at between 6 months and 4 years of age (1).
Although SOM usually improves, a delay in diagnosis and treatment may result in sequelae and complications because it is a silent process. Therefore, the early and appropriate treatment of this disease is crucial. Complications caused by SOM are divided into three types: speech and language, vestibular, and middle ear disorders. Hearing loss resulting from SOM can lead to improper speech and language development, which in turn can contribute to an impaired cognitive function and poor school success (2). Studies have shown that vestibular disorders may occur in young children with otitis media (3, 4) and that otitis media causes deterioration in middle ear structures over the long term (5).
In this context, it is meaningful to ask whether the presence of foreign body in a child's ear simply reflects a meaningless pattern of behavior or indicates the presence of ear disorders. It has been suggested that the presence of foreign body in the external acoustic meatus is a marker for SOM in children (6). Therefore, the purpose of this study was to determine whether a relationship exists between the presence of foreign body in the external acoustic meatus and ear disorders.
This prospective controlled study was conducted according to the principles of the Declaration of Helsinki at the Department of Otorhinolaryngology University of Health Sciences Gaziosmanpasa Taksim Training and Research Hospital. The study protocol was approved by the ethics committee of the University of Health Sciences Gaziosmanpasa Taksim Training and Research Hospital (Approval number: 2016/33). The parents of the children were informed regarding the characteristics of the research, and written consent for the involvement of the children was obtained from all parents.
All children diagnosed with foreign body in the external acoustic meatus were recruited. Children with mental or learning difficulties; those with prior ear surgery; those aged <2 years; and those with a history of oral, palatal, or nasal surgery were excluded, as were those in whom serious bleeding occurred in the external acoustic meatus during the removal of the foreign body.
The control group comprised 46 randomly selected children who came to the pediatric outpatient department with non-ear, nose, and throat (ENT) complaints (e.g., abdominal disorders) and who had no previous history of foreign body in the external acoustic meatus.
Assessment parameters included age, sex, the side of the ear with the foreign body, the type of the foreign body, the duration of the presence of the foreign body, and details of the removal of the foreign body.
We evaluated tympanometry results according to the classification system developed by Zeilhuis et al. (7). This classification system is a type of Jerger's nomenclature (8) and divides the tympanometry results into four subgroups: types A, B, C1, and C2 (Table 1). Types C1, C2, and B were regarded as abnormal (Table 1).
Number Cruncher Statistical System 2007 software (Kaysville, UT, USA) was used for all analyses. The independent samples t-test was used to analyze quantitative data, and Pearson's chi-square test was used to analyze qualitative data. Statistical significance was accepted at p<0.05.
Forty-six children with foreign bodies in the external acoustic meatus comprised the study group, and 46 with non-ENT disorders comprised the control group. Two children had foreign bodies in both ears. All children were assessed by an experienced otolaryngologist. The sex ratio (p=0.999) and mean age (p=0.865) did not significantly differ between the groups. There were 26 (56.5%) boys and 20 (43.5%) girls in each group.
Thirty-two (69.6%) children presented within 3 d of foreign body insertion into the external acoustic meatus. Four (8.7%) children applied to the hospital between 4 and 7 d of foreign body insertion, and six (13.0%) applied after 7 d. In four (8.7%) children, there was no information on how long the foreign body was in the ear. Twenty-five (54.3%) children had one foreign body in the right ear, 19 (41.3%) had one foreign body in the left ear, and two (4.3%) had one foreign body in both ears. The most frequent foreign body, i.e., a piece of paper, was found in 18 (39.1%) children; other foreign bodies included beads, various types of plastic pieces, pieces of crayon, and food. In two (4.3%) patients, general anesthesia was required, whereas 44 (95.7%) patients had the foreign body removed as outpatients. Demographic characteristics of patients and controls are summarized in Table 2.
As shown in Table 3, 20 (43.5%) children had a history of previous ear complaints, such as hearing loss, discomfort in the ear, or pain, within the past 6 months.
In the study group, 15 (32.6%) children had type A tympanogram, 7 (15.2%) had type C1, 9 (19.6%) had type C2, and 15 (32.6%) had type B tympanogram. In the control group, 34 (73.9%) children had type A tympanogram, 5 (10.9%) had type C1, 3 (6.5%) had type C2, and 4 (8.7%) had type B tympanogram. There were statistically significant differences in the percentages of children with type A and B tympanogram between the study and control groups. The percentage of children with type B tympanogram was significantly higher (p=0.005) in the study group and that of children with type A tympanogramwas significantly higher (p<0.001) in the control group (Table 3, Figure 1).
In the study group, nine children had abnormal findings, including SOM or Eustachian tube dysfunction (ETD), in the ear with the foreign body and a normal opposite ear, and 22 had SOM or ETD in both ears (bilateral foreign bodies were detected in two children). In the remaining 15 patients, all parameters were within the normal limits (Table 4).
We found that 67.4% (31/46) children in the study group had different middle ear disorders compared with 26% (12/46) in the control group. There was a statistically significant difference in the percentage of children with type B tympanogram (p=0.005) between the groups. The percentage of children with type C1 tympanograms (15.2%, 7/46) and type C2 tympanograms (19.6%, 9/46) were higher in the study group than in the control group, but these differences were not significant. Twenty (43.5%) patients in the study group had a previous history of ear complaints and disorders, whereas none in the control group had a history of any ear disorder.
Children with SOM may complain of earache, hearing loss, or tinnitus, and the parents of such children may also report hearing loss, imbalance, or recurrent otitis media. However, in a significant proportion of patients, particularly in young children, SOM may be overlooked because of the mild symptoms of the disease (9). This may explain why complications related to this disease are frequently observed.
Significant hearing loss has been reported to lead to an abnormal progress of speech and language (2, 10, 11) and also bring about poor school success and poor cognitive function (12, 13). Furthermore, SOM can disrupt middle ear structures and cause permanent sequelae, including tympanic membrane perforation, chronic suppurative otitis media, tympanosclerosis, adhesive otitis media, middle ear bone necrosis, retraction pocket, cholesteatoma, and sensorineural hearing loss. These complications are very rare in patients who are appropriately treated (14).
Several studies have revealed the co-occurrence of foreign bodies in the external acoustic meatus and ear disorders. Some studies have revealed that aural foreign bodies may be an indicator of SOM in children. For the first time, in 1972, MacGillivray (15) reported three patients who had SOM presenting as foreign body in the external acoustic meatus. He stated that foreign body in the external acoustic meatus in children may indicate an ear disorder, and children with foreign body in the external acoustic meatus should be evaluated by an ENT physician. Sarkar et al. (6) investigated 74 children with foreign body in the external acoustic meatus and found that 32.4% of these children had type A, 13.5% had type C1, 16.3% had type C2, and 37.8% had type B tympanogram. Ansley and Cunningham (16) achieved similar results in their study and suggested that hearing loss, external acoustic meatus irritation, or otalgia prompted the children to put something in the ear. Schulze (17) reported 698 pediatric patients with foreign bodies in the external acoustic meatus and showed that the frequently presenting concomitant pathology was otitis media, which presented in 5.3% of patients.
Our study suggests that ETD and SOM cause irritation in children's ears that prompts them to put something in the ear to ease external acoustic meatus irritation. We propose that all children with foreign body in the external acoustic meatus should be examined by an otologist to prevent the delay in diagnosing middle ear disorders. The results of our study reveal a relationship between foreign body in the external acoustic meatus and ear disorders, and a foreign body in the external acoustic meatus may point to an ear disorder and should not be ignored.
