Sensorineural Hearing Loss among Hypertensives.

BACKGROUND: The effect of hypertension on the vascular system leads to Target Organ Damage (TOD). The cochlea is one of the target organs affected by hypertension, giving rise to Sensorineural Hearing Loss (SNHL). OBJECTIVE: To determine the prevalence and pattern of Sensorineural Hearing Loss (SNHL) among hypertensives. DESIGN: Case-Control Study. SETTING: Tertiary hospital. SUBJECTS: Two hundred and twenty six hypertensives, aged 21 to 60 years and a corresponding number of age and sex matched control. METHODOLOGY: Eligible participants were prospectively evaluated. Their blood pressures were verified, hearing thresholds assessed through Pure Tone Audiometry, Pure Tone Average were calculated and the types and degree of hearing loss were confirmed. Data was analyzed using SPSS 21 and statistical significance was set at p-value 0.05. RESULTS: Each group had 127 (56.19% ) females and 99 ( 43.81 % ) males. The difference in the mean age between the cases (40.02 ± 0.70years) and the controls (37.42 ± 0.47years) was not statistically significant (p = 0.542).The difference in the mean Pure Tone Average in dBHL between the cases (15.53± 6.95) and the controls (13.98 ± 4.35) was significant (p = 0.005) with a 12.83% prevalence of SNHL among the hypertensives against 1.77% in the controls. Majority (96.6 %) of them demonstrated bilateral, symmetrical, mild SNHL with 51.7% of them being above 50 years. The odds ratio in this study was 8.17 (p = 0.0001). CONCLUSION: This study demonstrated a SNHL prevalence of 12.83% with a mild, bilateral, symmetrical pattern among hypertensives; increasing with advanced age and an eight-fold risk of occurrence.

Age-related hearing loss at Gwagwalada area council of federal capital territory, Abuja.

BACKGROUND: Presbyacusis is a cause of hearing loss in adults worldwide. It is a type of auditory dysfunction thought to be due to a series of insults over time including agerelated degeneration, noise exposure, and diseases of the ear. It usually affects the high frequencies of hearing. Presbyacusis has a tremendous impact on the quality of life of millions of the aged and is fast becoming an increasingly prevalent disorder as the population ages. Nigerian population is becoming progressively older making it imperative to focus on this area of research. It is worth noting that the Nigerian public health system does not have an effective and sustainable hearing loss screening strategy for lateonset hearing loss in adults. AIM/OBJECTIVE: This study evaluated the hearing threshold and pure tone audiometric pattern/s seen in participants with agerelated hearing loss (ARHL) in Gwagwalada Area Council of the Federal capital territoryAbuja. SUBJECTS AND METHODS: The study was a prospective communitybased crosssectional study, and a multistage sampling technique was adopted for this study, conducted at Gwagwalada, Abuja. Individuals from 55 years and above were recruited into the study after signing an informed consent. After a thorough and detailed clinical assessment, tympanometry and diagnostic puretone audiometry were carried out in all the participants. RESULT: One hundred and fourteen participants were recruited into the study, out of which fourteen were excluded from the analysis on account of various exclusion criteria. The age range of the participants was 55 to 79 years, with a mean age of 65.8 ± 5.6 years.Twentyfive (25.0%) participants had normal hearing threshold, while seventyfive (75.0%) participants had sensorineural hearing loss (SNHL). CONCLUSION: The study showed that the prevalence of ARHL from age 55 years and above at Gwagwalada Area Council, of FCT, Abuja was 75.0%.

Long-term effects of Maternal HIV Infection and Anti-Retroviral Medications on the Hearing of HIV-Exposed Infants.

BACKGROUND: The long-term effect of maternal HIV and antiretroviral medication on the hearing of HIV-exposed infants has not been well studied. We determined and compared the hearing thresholds of HIV-exposed infants with that of HIV-unexposed infants within the first month of life and at three, six and nine months of life. MATERIALS AND METHODS: This was a Case control study of 126 HIV-exposed newborns and 121 HIV-unexposed newborns. Data collected included Socio-demographic, clinical characteristics and risk factors for hearing loss. Hearing was evaluated at newborn, 3, 6, and 9 months of life. Within and between groups analyses were done with appropriate statistics. Level of significance was P<0.05. RESULTS: In both ears, the mean hearing thresholds of HIV-exposed infants were greater than those of the HIV-unexposed infants at baseline, 3, 6 and 9 months (P>0.05). In both groups, there was a decline in the mean hearing thresholds from baseline (new born) till 6 months of age. The highest mean threshold was recorded at 9 months. The mean hearing thresholds of infants at 3, 6, and 9 months were lower for HIV-exposed infants and higher for HIV-unexposed infants than the corresponding mean hearing thresholds measured at baseline. There was a significant strong correlation among hearing thresholds at 3, 6 and 9 months but weakly correlated with hearing thresholds at baseline. CONCLUSION: There was a tendency towards higher hearing thresholds in HIV-exposed infants than the HIV-unexposed infants throughout the infancy period. This appears to have association with in-utero exposure to HIV.

Comparison between olfactory function of pregnant women and non-pregnant women in reproductive age group in Ibadan, Nigeria.

BACKGROUND: Pregnant women require normal olfactory function in order to develop good appetite for healthy living and normal fetal development. This study was carried out to investigate and compare olfactory function of pregnant women with non-pregnant women. METHODS: This was a case control study of women in reproductive age group at the University College Hospital, Ibadan, Nigeria from July 2014 to February 2015. Consecutive 70 pregnant women and 70 non-pregnant women (controls) without rhinologic symptoms were studied. A structured questionnaire was administered to obtain participants' information on socio-demographics, pregnancy history, and ability to perceive smell. They subjectively rated their olfactory function on a visual analogue scale of 0 - 100. Olfactory threshold (OT), discrimination (OD), identification (OI) scores and TDI of both groups were determined with"Sniffin' sticks"kits and compared. The level of significance was P<0.05. RESULTS: The mean age of the pregnant women was 30.5±3.9years and control was 28.5±6.6years. There were more pregnant women (7.1%) with hyposmia than the non-pregnant women (2.9%). The subjective rating of olfactory function was 68.2±24.9 (median 70) and 72.3±21.6 (median 69) in pregnant women and controls respectively. The mean OT, OD, OI, TDI scores were higher in pregnant women than the controls. However, it was only in OI (P=0.000) and TDI (P=0.012) that the differences were significant. CONCLUSIONS: Pregnant women have olfactory dysfunction more than the non-pregnant women of reproductive age group. Also, they have tendency to develop loss of cognitive olfactory information more than the non-pregnant women.

Is there any relationship between hearing threshold levels and CD4 cell count of human immunodeficiency virus infected adults?

Background The role of viral load level and/or CD4 (Cluster of differentiation 4) cell count in the aetiopathogenesis of hearing loss in HIV infection is unclear. Therefore, we investigated the relationship between CD4 cell counts, viral load and hearing threshold of HIV (Human immunodeficiency virus) infected adults. METHODS: This cohort audiometric study involved consecutive HIV-infected and HIV-uninfected adults as controls. Clinical data relating to hearing loss, HIV status, and highly -active antiretroviral therapy (HAART) were obtained. Audiornetric evaluation was performed. The most recent CD4 cell counts and RNA viral load-of HIV-infected participants were obtained from clinic records. RESULTS: There were 299(66.7%) HIV-infected adults and 149(33.3%) controls with mean age of 39.64± 12.45 years and 39.60±12.45 years respectively (p=0.98). In both groups, there were more participants with left hearing loss. Mild to profound hearing loss was found in 65.9% HIV- infected participants and 53.7% controls. Majority (86.3%) of the HIV-infected participants were on HAART. The mean CD4 cell count was 654.58±289.15 in 41 HIV-infected participants not on HAART and 523.95±300.17 in 258 participants on HAART (p=0.01). Majority,- 197 (62%) HIV- infected participants with hearing loss had CD4 cell count ≤200 cells/mm3. Higher viral load significantly correlated with low CD4 cell counts (p<0.0 1; r=0. 18) and low CD4 cell count significantly correlated with high hearing threshold (p

Sensorineural Hearing Loss and Dyslipidemia: Is There Any Relationship?

BACKGROUND: The incidence of dyslipidemia is increasing worldwide due to changes in diet and lifestyle. The aetiological role of dyslipidemia in sensorineural hearing loss (SNHL) is unclear. OBJECTIVE: To determine the association between SNHL and dyslipidemia in adult Nigerian population. DESIGN OF THE STUDY: This prospective case control study was carried out at ENT Department of University College Hospital Ibadan from August 2013 to May 2014. METHODS: The study involved consecutive adult patients (18-60 years) with SNHL. The controls were adults without SNHL matched for age, gender and socioeconomic status. Relevant clinical data were obtained. Hearing threshold was determined by standard method and fasting plasma lipid assayed for triglycerides (TG), total cholesterol (TC), high density and lipoprotein-cholesterol (HDL-C). The low density lipoprotein-cholesterol (LDL-C) was calculated from TG, TC and HDL-C using Freidewald's formulae. The values of <40mg/dl, >200mg/dl, >150mg/dl and >130mg/dl were considered abnormal for HDL-C, TC, TG and LDL-C respectively. Level of statistical significance was P<0.05. RESULTS: There were 108 participants, consisting 57 (67.7%) cases and 51 (32.9%) controls with mean age of 37.911.3 years and 37.4 11.3-year respectively (p=0.708). Abnormalities in HDL-C values was the commonly observed in both cases (64.9%) and controls (76.5%).Thirty-six (63.2%) cases had severe to profound hearing loss. There was no significant correlation between lipid parameters and severity of SNHL. CONCLUSION: The prevalence of dyslipidemia in adult patients with sensorineural hearing loss is similar to those with normal hearing. There appears to beno causal association between dyslipidemia and sensorineural hearing loss.

Comparative study of aerobic pathogenic bacteria isolates from patients with recurrent tonsillitis.

BACKGROUND: To find out if isolated aerobic bacteria pathogens from surface tonsillar swab can correctly predict the infective pathogens within the core tonsillar tissues in recurrent tonsillitis. METHODS: This was a prospective, hospital based study of 60 patients with recurrent tonsillitis at University College Hospital, Ibadan, Nigeria. Surface swabs of the infected-tonsils-biopsies-of the core tonsillar tissues were obtained. Microscopy, Culture and Sensitivity studies were performed on the specimens. The aerobic pathogens were isolated by standard microbiological methods. Data analysis was done by SPSS version 20.0. RESULTS: Only 54 (90%) surface swab specimens yielded aerobic pathogens while 47 (78.3%) core tissue specimens yielded aerobic pathogens. The tonsil surface swab for identification of aerobic pathogenic bacteria has a sensitivity of 97.7%, specificity of 31.3%, positive predictive value or precision of 79.6%, negative predictive value of 83.3% and accuracy of 80%. Overall, there was no statistical significant difference in the aerobic pathogenic organisms isolated from surface tonsillar swab and core tonsillar tissue specimens (p=0.103). CONCLUSION: Aerobic bacteria pathogens grown on tonsillar surface were not significantly different from those from core tonsillar specimenshence, the tonsillar surface swab can reliably be used to identify the pathogenic organisms in recurrent tonsillitis.

Comparing Oxygen Saturation of Normal Children with that of Children with Adenotonsillar Hypertrophy.

To compare the nocturnal oxygen saturation profiles of children with adenotonsillar enlargement with that of normal children. A 1 year comparative study. The study was carried out at the Otorhinolaryngology Ward of the University College Hospital Ibadan. These comprise of 60 children (1-9 years) with clinically confirmed adenotonsillar enlargement admitted for adenotonsillectomy and 60 normal children matched for age and sex. The biodata and common clinical presentations of the study group were acquired with a structured proforma. The severity of nasopharyngeal obstruction was determined by the adenoidal-nasopharyngeal ratio while the degree of tonsillar enlargement was graded by the Brodsky's classification. The nocturnal oxygen saturation of all the participants were recorded with a wrist worn pulse oximeter. Recording was for at least for 4 h. Oxygen saturation <92 % was regarded as desaturation. The oximetric values of the study and control group were compared. The mean nocturnal SPO2 (peripheral saturation of oxygen) profiles of children with adenotonsillar enlargement were as follows: basal = 96.86 %, minimum = 84.99 %; maximum = 99 % and average SPO2 <92 % = 87.74 % while the saturation profiles of the control group were as follows; basal = 97.88 %, minimum = 89.71 %; maximum = 99 %, average SPO2 <92 % = 90.82 %. Normal children have better nocturnal saturation profiles than children with adenotonsillar enlargement.

Sensorineural hearing loss in patients with chronic suppurative otitis media.

Even though there are other complications of chronic suppurative otitis media, the aspect of hearing loss is often studied. Nevertheless, the occurrence of sensorineural hearing loss in patients with this disease is still controversial. This study aim (1) to assess the association between sensorineural hearing loss and chronic suppurative otitis media, (2) to investigate some clinical factors that might affect the sensorineural component in patients with this disease. This was a retrospective analysis of the clinical records and pure tone audiograms of patients with chronic suppurative otitis media in a Nigerian Tertiary Health Institution from January 2003 to December 2008. Sixty-nine patients with a mean age of 28.93 years; standard deviation of 18.593 were studied. They had an age range of 4-73 years. The duration of otorrhea ranged from 2 months to 20 years; with a mean of 6.11 years (standard deviation of 6.393). The mean bone conduction threshold in the diseased ear was 39.07 dB (standard deviation of 12.028), and 10.26 dB (standard deviation of 2.620) in the control ear (P < 0.05). The mean bone conduction threshold differences between the diseased and control ears range from 21.69 to 34.52 dB across the frequencies 0.5, 1.0, 2.0, and 4.0 kHz. These differences tended to increase with increasing frequency and were all significant (P < 0.05). In the diseased ears, there were no significant correlation between the age, duration of otorrhea, and the degree of SNHL (r = 0.186, P > 0.05; r = 0.190, P > 0.05 respectively). Patients with chronic suppurative otitis media had a significant degree of sensorineural hearing loss in this study. The higher frequencies were more affected; however, the patient's age and duration of otorrhea seem not to have any correlation with the degree of sensorineural hearing loss.

Classification and management challenges of otitis media in a resource-poor country.

The clinical features and sequelae of otitis media (OM) vary depending on the duration, severity and progression of the disease. As a result, opinions on the modes of classification and management protocols have differed over the years. The need to critically appraise these opinions according to the peculiarities of each region is imperative. This work was aimed at reviewing the world literature on the subject and also highlights the limitations in management in our region. A wide literature search was conducted using the following search engines: PubMed, AJOL and University of Toronto Library. Also incorporated were essential materials obtained from the authors' clinical practices. The search engines returned 22,903 related articles on OM. Further filtration yielded 88 articles on "classification and management" and these were obtained in full and thoroughly read. Extracted materials for review spanned between 1980 and 2008. OM is prevalent the world over with potentially severe complications if inadequately managed, especially in the developing countries. It is of note that in the developing countries, poverty, ignorance, dearth of specialists and limited access to medical care amongst others conspire to worsen the course and complications of OM.

Plain radiographic evaluation of children with obstructive adenoids.

BACKGROUND: There are several methods of evaluating adenoidal size pre-operatively. Plain nasopharyngeal radiography is a common investigative modality: it has been advocated, and also condemned. AIM: This study was intended to assess nasopharyngeal airway obstruction by the adenoids using plain X-rays; and also to find correlation if any, with the symptomatology. METHODS: This is a retrospective study carried out between January and December 2008. The case notes and plain X-rays of the nasopharynx of 34 paediatric patients with clinical features of obstructive adenoids were analyzed. RESULTS: A total of 34 children were studied, 22 (64.7%) were males and 12 (35.3%) were females. Their ages ranged between 7 months and 10 years: mean age was 3.55 years, standard deviation 2.723. Majority (67.6%) of the children were in the age group 0-4 years. The lowest symptomatology assessment score was 0 and the highest was 3. Children 4 years and below had the highest symptomatology scores. The minimum adenoidal-nasopharyngeal ratio was 0.35 and the maximum was 0.94. There was no significant difference in the mean adenoidal-nasopharyngeal ratio of males and females (t=0.407; p=0.692). Many (75.0%) of the children with moderate to severe nasopharyngeal airway obstruction by the adenoids were in the age bracket 0-4 years. The lowest adenoidal-nasopharyngeal ratio score was 0 and the highest was 3. Children 4 years and below had the highest adenoidal-nasopharyngeal ratio scores. There was a very weak nonsignificant correlation between the symptomatology assessment score and the radiological assessment score (r=0.168; p=0.375). CONCLUSION: The adenoidal-nasopharyngeal ratio is reliable in assessing the nasopharyngeal airway in children with obstructive adenoids.

Routine Electrocardiography Request in Adenoidectomy: Is it necessary?

To evaluate the relevance of routine electrocardiographic request in pre-operative work-up of children undergoing adenoidectomy. This is a two year prospective study of children with obstructive adenoid that had adenoidectomy. This is a tertiary hospital based study at the Otorhinolaryngology Department of University College Hospital, Ibadan. Children (≤12 years) with clinical and radiological evidence of an obstructive adenoid were investigated. Information obtained with an interviewer assisted questionnaire included the biodata, clinical presentation of the patients, ECG findings, echocardiographic findings, cardiothoracic ratio, palatal airway and ratio of adenoid diameter to the nasopharyngeal diameter. The adenoid volume was measured after adenoidectomy. The results were analyzed using SPSS version 14 and level of statistical significance was P < 0.05. There were seventy four patients; 45 (60.8%) males and 29 (39.2%) females with a mean age of 38.35 months, S.D ± 30.32 (range 5-144 months). All the patients presented with mouth breathing and recurrent mucopurulent rhinorrhea. Mild snoring was detected in 18 (25%) patients, moderate snoring in 39 (54.17%) patients and severe snoring in 15 (20.83%) patients. Mild apnea was observed in 55 (74.32%) patients and moderate in 19 (25.68%) patients. Only seven (9.46%) patients had abnormal electrocardiographic findings but their ejection fraction on echocardiography ranged from 63 to 72% with a mean value of 68.17%, S.D ± 3.22. Cardiac complications of enlarged obstructive adenoid appear not to be common. Routine preoperative electrocardiography should therefore be restricted to only the high risk patients.

Adult Chronic Rhinosinusitis:Spectrum of Clinical Features and Management in aTertiary Health Institution and Literature Review

Background:Rhinosinusitis is defined as inflammation of the nasal and paranasal sinus mucosa.Chronic rhinosinusitis occurs when this inflammation and the symptoms persist for more than 3 months.The objective of this study was to evaluate the clinical features and management of adult chronic rhinosinusitis in a tertiary health institution and to review the literature for its current modalities of management.Methods:This is a 5-year retrospective study of all adult patients managed for clinically and radiologically diagnosed chronic rhinosinusitis at the study center.Their medical records were reviewed for essential data which included demographic data; clinical presentations; skin sensitivity test; radiologic reports and treatment offered.The data were collated and analyzed using simple descriptive statistics.Results: There were 228 patients; 97(42.54) males and 131(57.46) females with a male:female ratio of 1:1.35; age ranged between 18 - 67 years (mean =35.2).The five major presenting symptoms were nasal discharge 228(100.00); nasal obstruction 224 (98.25); equent throat hawking 189 (82.89); itching of eye; ear; nose or throat 138 (60.53) and excessive sneezing 136(59.65).About 6of the patients developed complications.Allergy accounted for the cause in 93 (40.79)patients. Maxillary antral mucosal thickening and engorged inferior turbinates were the commonest radiological features. About 51of the patients were treated with intranasal inferior meatal antrostomy with or thout inferior turbinectomy.There was recurrence of symptoms in about 18of these patients from 3 to 8months after surgery.Conclusions: Both subjective and objective measures should be employed in the diagnosis of chronic rhinosinusitis and intranasal inferior meatal antrostomy may rarely produce satisfactory clinical improvement

Swab and aspiration specimen collection methods and antibiogram in chronic suppurative otitis media at Jos University Teaching Hospital: Which is superior?

BACKGROUND: Chronic suppurative otitis media is a very common otologic problem in our environment. Appropriate methods for obtaining sample specimens for specific bacteria isolation has generated a lot of controversy. The simplest method available in our environment is the traditional swab method which, however, has been condemned on the basis of introducing contaminants. The objectives of this study were to compare the bacterial yield and the antibiogram of two specimen collection methods: the traditional swab method and aspiration method. METHOD: This was a 3-month prospective study involving outpatients seen at both the emergency and outpatients' clinics of the Jos University Teaching Hospital in the period between May 2008 and July 2008. The biodata, duration of discharge and sites of samples were recorded in the study data form after obtaining consent from the patients or the parents of child. RESULTS: Eighty patients were studied comprising 40 each for aspiration and swab technique. This consists of 30 males (37.5%) and 50 females (62.5%) with a male to female ratio of 1:1.7. There were 24 (30%) children (14 males, 10 females). Six (4 males, 2 females) and 74 (26 males, 48 females) patients had bilateral and unilateral ear discharges, respectively. A total of 86 specimens were obtained in all, consisting of 42 left and 44 right ears. There were 68 bacteria isolates comprising Pseudomonas (30), Staphylococcus (18), Proteus (12), and (8) Klebsiella species. Two were incidental fungal isolates of (Candida species), (8) cultures grew contaminants and (10) specimens had no growth at all. Each of the swab and aspiration techniques had (44) specimens. CONCLUSIONS: Despite the controversy surrounding the sampling technique in literature, swab technique has been found to be as good as the aspiration technique in our study. The organisms isolated are the same as those obtained in other places. Contaminants found were few and occurred in equal amount in the same patients in the two methods.

Tracheostomy Decannulation: Suprastomal Granulation Tissue in Perspective

Background: Suprastomal granulation tissue is a complication of tracheostomy which maymake decannulation difficult and presents a therapeutic challenge to the Otorhinolaryngologists. The aims of this study therefore were to evaluate tracheostomy in black African population; determine the prevalence of suprastomal granulation tissue and provide updated information on it that will enable the otorhinolaryngologists to better understand and manage the lesion. Methods: We reviewed case files of patients who had tracheostomy between 1993 and 2007 at University College Hospital; Ibadan; Nigeria for essential clinical data.Results: Of the 256 patients who had tracheostomy; 133(51.95) had prior orotracheal intubation for 10 21days. Suprastomal granulation tissue complicated 16 (6.25) cases; this accounted for 88.89of cases of failed decannulation. Indications for tracheostomy in these patients included severe head injury in 12 (75); tetanus in 3 (18.75)] and intubation granuloma in 1(6.25) of these cases. Sixteen (4.3) cases had stomal infection. Conclusion: This study showed that the prevalence of suprastomal granulation is high among our patients. There is a need for good surgical tracheostomy technique to prevent this complication and stomal infection should be promptly treated while cuffed orotracheal intubation for more than two weeks in unconscious and tetanus patients should be avoided

Experience with rigid esophagoscopy in Jos, north-central Nigeria.

OBJECTIVE: Esophagoscopy which may be done for either a therapeutic or diagnostic reason has remained useful in the management of esophageal diseases. This study evaluates our experience with rigid esophagoscopy with special emphasis on esophageal foreign bodies in our unit. METHOD: This is a six-year (January 2000-December 2005) retrospective review of cases of rigid esophagoscopy in the Ear, Nose and Throat Unit of our center. RESULTS: Fifty-seven patients with ages ranging from 10 months 75 years were studied. There were 35 (61.4%) males and 22 (38.6%) females. Fifty-three of the patients (93%) had varying foreign bodies in the esophagus, 3 (5.2%) patients had carcinoma of the esophagus while 1 (1.8%) had pharyngeal pouch. The 0-10 year age group had the highest prevalence of esophageal foreign bodies (66.0%) with the middle third of the esophagus been the commonest site of impaction (58.5%). There was no fatality recorded. CONCLUSION: Rigid esophagoscopy is a relatively safe procedure in trained hands and ideal environment with the necessary facilities in place.

Cervical necrotizing fasciitis: case series and review of literature.

INTRODUCTION: Cervical necrotizing fasciitis is a fatal and rapid multi- bacteria infection causing extensive necrosis of the subcutaneous tissues and fascial planes with resultant skin gangrene and associated systemic manifestation. The aim of the present study is to report four cases of cervical necrotizing fascitis highlighting their source. METHOD: The case notes of the patients were retrieved and reviewed, literature search was done using Medline, journals available and various texts. RESULTS: Most often the cause of cervical necrotizing fascitis is of dental origin. The diagnosis depends mainly on clinical features and a high index of suspicion because the clinical features maybe innocuous at the early stage. CONCLUSION: Despite aggressive management with liberal wound debridement, intravenous antibiotics, and nutritional support, the mortality was still high due to late presentation.

Quantitative analysis of tympanic membrane perforation: a simple and reliable method.

BACKGROUND: Accurate assessment of the features of tympanic membrane perforation, especially size, site, duration and aetiology, is important, as it enables optimum management. AIM AND OBJECTIVES: To describe a simple, cheap and effective method of quantitatively analysing tympanic membrane perforations. MATERIALS AND METHODS: The system described comprises a video-otoscope (capable of generating still and video images of the tympanic membrane), adapted via a universal serial bus box to a computer screen, with images analysed using the Image J geometrical analysis software package. The reproducibility of results and their correlation with conventional otoscopic methods of estimation were tested statistically with the paired t-test and correlational tests, using the Statistical Package for the Social Sciences version 11 software. RESULTS: The following equation was generated: P/T x 100 per cent = percentage perforation, where P is the area (in pixels2) of the tympanic membrane perforation and T is the total area (in pixels2) for the entire tympanic membrane (including the perforation). Illustrations are shown. Comparison of blinded data on tympanic membrane perforation area obtained independently from assessments by two trained otologists, of comparative years of experience, using the video-otoscopy system described, showed similar findings, with strong correlations devoid of inter-observer error (p = 0.000, r = 1). Comparison with conventional otoscopic assessment also indicated significant correlation, comparing results for two trained otologists, but some inter-observer variation was present (p = 0.000, r = 0.896). Correlation between the two methods for each of the otologists was also highly significant (p = 0.000). CONCLUSION: A computer-adapted video-otoscope, with images analysed by Image J software, represents a cheap, reliable, technology-driven, clinical method of quantitative analysis of tympanic membrane perforations and injuries.

An unusual oronasal foreign body: report of a case.

BACKGROUND: Foreign body removal in children is very common in the daily routine of an otolaryngologist but reports of oronasal foreign bodies and their management are rare. METHOD: The case note of a 5-year-old female child presenting with an oronasal foreign body following a domestic accident was retrieved and studied and followed up. RESULT: a 5-year-old female child with an oronasal foreign body which created an oronasal fistula that was closed with local palatal mucoperiosteal-lined flaps. The patient defaulted following treatment, a common practice by patients in our society. CONCLUSION: This report highlights the occurrence of this rare condition, its management and the need to put measures in place to prevent domestic accidents especially for those most at risk.
