Outcome analysis of palatoplasty in various types of cleft palate.

AIMS: To analyse the factors affecting clinical and functional outcome of Veau-Wardill-Kilner palatoplasty in various types of cleft palate. MATERIALS AND METHODS: Demographic data were retrieved from case records and a detailed speech, language and hearing and an orthodontic analysis were carried out prospectively. RESULTS: Mean age at operation was 2.7 years; whereas mean age at the time of evaluation was 6 years. Most of the patients (43.3%, 13/30) had a bilateral cleft lip and palate. The postoperative fistula had developed in 31% (4/13) of the patients with bilateral clefts and in 17% (1/6) and 9% (1/11) of the patients with left unilateral and isolated cleft palate respectively (P<0.05). Eight per cent (2/24) of the patients operated before 2 years of age developed a fistula as compared to 66.6% (4/6) of the patients who had undergone a repair after 2 years of age (P<0.01). Severe speech abnormality was seen in 33.4% of the patients having postoperative fistula as compared to 16.6% of non-fistula patients (P<0.05). Derangement of speech was found in 66.6% of the patients who had undergone surgery after the age of 2 years as compared to the patients (13%, 3/24) undergoing correction before 2 years of age (P<0.05). Hearing loss was seen most commonly in patients with bilateral cleft palate as compared to the other varieties (P>0.05). Tympanic membrane (TM) abnormalities were also more common in bilateral cleft patients (P<0.05). Mean maxillary arch length, arch circumference and maxillary inter-canine and inter-molar width were significantly reduced as compared to the control group (P<0.001). CONCLUSIONS: Socially acceptable quality of speech can be achieved in more than 85% of the patients. The postoperative fistula is associated with poor speech; bilateral cleft and older age being the risk factors for fistula formation. Many patients require audiological surveillance even when asymptomatic. Maxillary growth is impaired in all the patients despite early surgery.

Transient evoked otoacoustic emissions in hearing screening programs: protocol for developing countries.

OBJECTIVES: To formulate a protocol for infant hearing screening in developing countries enabling it to be later incorporated into their national deafness screening programs. The screening tool should be sensitive in detecting hearing loss in infants with high specificity. METHODS: 2659 infants in the age range of 0-3 months who reported to the Department of Otolaryngology were included in the study. As 537 children were lost to follow up after the first screening, the remaining 2122 infants only were considered for the statistical analysis. These were divided into 3 groups with age range between 0-1, 1-2 and 2-3 months of age. All were subjected to transient evoked otoacoustic emission (TEOAE) for hearing screening. Those who failed first screening were followed up after 1-month. Pass rate for TEOAE was calculated for each. Infants who had failed the second screening underwent Brainstem Evoked Response Audiometry (BERA). The data collected was statistically analyzed. RESULTS: 77.5% of infants in 0-1-month age group passed the screening test whereas 83.4% and 92.8% of infants passed the screening test in 1-2 months and 2-3 month age groups, respectively. On the first follow up, the pass percentage of the infants who had failed screening earlier rose significantly high up to age of 3 months. Those who had failed the follow up were scheduled for Brainstem Evoked Auditory testing. CONCLUSION: The concept of this delayed hearing screening at 3 months of age would considerably decrease the number of false positive cases undergoing unnecessary investigations and wastage of resources making the universal neonatal hearing screening within 48 h of life impractical for developing countries. Combining this delayed hearing screening with the 3rd dose of universal immunization program would constitute a viable, feasible and universal hearing screening program, which can be drafted into national deafness programs of the developing countries.

Intervention strategies in children with cochlear implants having attention deficit hyperactivity disorder.

Attention deficit hyperactivity disorder (ADHD) is the most common neurodevelopmental disorder of childhood which not only affects child's education, development and peer functioning but is also associated with significant morbidity in areas of social and academic success. ADHD may hamper the language acquisition in hearing impaired children. When such children are scheduled for the auditory verbal therapy following cochlear implantation, the outcome is limited due to reduced attention span. We have presented two cases who had undergone cochlear implantation and showed the signs of ADHD. As there was little progress in listening skills and speech and language acquisition following 3 months of therapy, both children were referred to Psychiatry Department and were diagnosed as having ADHD. Following little improvement with behavior modification techniques, they were put on medication. Significant improvement was noticed with reduction in hyperactivity and increased attention span after the administration of the drugs.

Audio Vestibular Status in CML Patients on Imatinib Mesylate with Review of Literature.

Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm occasionally presenting with features of leukostasis as primary symptoms. Hearing loss is occasionally reported in CML patients. Further whether Imatinib mesylate has any effect on vestibular functions is not known. We conducted a preliminary study to assess hearing pattern in patients with CML on long term TKI therapy. This is a single center, cross sectional study from northern-India. Patients of CML who were on regular Tyrosine kinase inhibitors (TKI) therapy for at least 6 months underwent audiovestibular evaluation . A total of 44 CML patients on TKI therapy were assessed over a period of 6 months. The median age of the patients was 41 years, the mean duration of TKI therapy was 36 months. Four patients were found to have otological disorder clinically. On pure tone audiometry of 88 ears normal hearing pattern were found with at low and mid frequencies. There was a down sloping type of curve at higher frequencies in PTA in most of the patients. Cold caloric tests in 42 patients were found as equal response in both ears. We conclude from this preliminary study that there are no audio vestibular dysfunctions amongst patients of CML on TKI. It's a negative study wherein we have ruled out any auditory deficits secondary to Imatinib therapy. Further studies are required to evaluate the audiometric profile in CML patients before Imatinib therapy and to be compared with the patients already on Imatinib in a large cohort.

Reversible hearing loss associated with high-voltage electric shock.

Hearing loss associated with high-voltage electric shock is a rare entity and minimal information is available in the current literature about this condition. To our knowledge, this article represents the first case report in the literature of improvement in sensorineural hearing loss sustained due to a high-voltage electric shock. A case report of a patient who incurred various otologic problems, including hearing loss and tinnitus, is presented. An improvement in hearing loss and tinnitus was observed in the subsequent follow up after one month. Audiological findings and possible pathophysiology of hearing loss are discussed. We recommend that further studies be done to investigate the incidence, severity and pathophysiology of hearing loss in such cases.

Audiological manifestations of allergic rhinitis.

BACKGROUND: Allergic rhinitis is associated with excess specific immunoglobulin E. Inner ear involvement (via both cellular and humoral immunity) is poorly understood, but appears to arise from the endolymphatic sac and duct. AIMS: To assess the otological and audiological status of patients with allergic rhinitis. METHODOLOGY: Thirty allergic rhinitis patients (14 men, 16 women; age 17-45 years, mean 31 years) and 20 controls (12 men, eight women; age 21-42 years, mean 27 years) underwent audiological investigation. RESULTS: All study group patients had sensorineural (rather than conductive) hearing loss, worse at high frequencies. All had abnormal transient evoked otoacoustic emissions and 27 had abnormal distortion product otoacoustic emissions. All had a statistically significantly prolonged wave I latency, and shortened absolute wave I-III and I-V interpeak latencies, compared with controls. CONCLUSION: Allergic rhinitis patients had a higher prevalence of hearing loss and otoacoustic emission abnormalities than controls. The endolymphatic sac can process antigens and produce its own local antibody response; the resulting inflammatory mediators and toxic products may interfere with hair cell function. Additional research is needed to determine the clinical value of audiometry and otoacoustic emission testing in allergic rhinitis.

Speech impairment in Nijmegen breakage syndrome: a rare anomaly.

The subject of the case study was a 13 years old girl with Nijmegen breakage syndrome (NBS), having mild mental retardation and age inappropriate language skills. The case demonstrated severely delayed receptive and expressive language skills. The symptoms of NBS including congenital microcephaly, mild dysmorphic facial appearance, growth retardation, short stature, mental retardation, chromosome instability, speech and language delay were present in our case. Therefore treatment efforts were directed towards general speech and language stimulation techniques, expanding communicative intentions expressed, strengthening oro-facial musculature for articulatory precision, speech intensity and intelligibility. The client showed relatively better results over a short period of time. The favorable outcome of the present study provides an important example of the beneficial effects of therapy even for clients with poor prognosis.

The role of audiological diagnostics in children with cleft lip & palate (CLP).

OBJECTIVE: To assess the otologic and audiologic status of patients with cleft lip and palate (CLP) operated in the Department of Pediatric Surgery attached to the Advanced Pediatric Centre, Post Graduate Institute of Medical Education & Research (PGIMER), India. The main idea of carrying out this study was to know the incidence of middle ear pathologies in a group where no complaints have been noticed. SETTING: Research study was carried in Post Graduate Institute of Medical Education & Research (PGIMER) which is one of the tertiary care institutions in India. PARTICIPANTS: 55 children (Mch: 28; Fch: 27) in the age range of 4-13 years constituted the study group. These children were operated upon by the same surgeon (JKM) during the period 1996-1998 and were attending the speech clinics at PGIMER. None of these children/parents had complained of any ear problem and were taken up for the study to find out the middle ear pathology. The ontological and audiological evaluation was done for all the children. RESULTS: 53 of 110 ears had normal hearing status. None of the ears had severe or profound hearing loss. The air conduction thresholds ranged from 20.2 to 29.63 dB across the frequencies whereas the bone conduction thresholds varied from 7.13 to 12.41 dB. Only 42% of the right (R) ears and 47% of the left (L) ears had a normal tympanic membrane. CONCLUSION: On the basis of this finding, investigation of the benefits of early and routine follow-up for otologic and audiologic status is warranted. Patients with cleft lip and palate should have an intense and detailed otologic and audiologic follow-up to identify any ME pathology/hearing loss so that timely intervention can be taken.

Personality changes and the role of counseling in the rehabilitation of patients with laryngeal cancer.

We conducted a study of 65 adults who had undergone laryngectomy for the treatment of laryngeal cancer. Our goal was to identify any abnormal personality traits in these patients and to assess the effect that psychological counseling might have on correcting these abnormalities and thereby improving postoperative voice rehabilitation. A Personality Trait Inventory (PTI) administered to all patients preoperatively identified 47 patients who had abnormal scores for at least three personality traits. These 47 patients were sent for preoperative psychological counseling, and 3 months following surgery, they underwent a follow-up PTI. At the follow-up assessment, 40 of these patients-32 men and 8 women-still registered abnormal scores for at least three traits. Half of the men and half of the women were randomized to receive 12 sessions of individualized psychological counseling over 6 months in addition to standard speech therapy (group I); the other patients received speech therapy only (group II). A follow-up PTI was administered at the completion of psychological counseling and/or speech therapy (postoperative month 9). Statistical analysis of the data was performed with the paired-samples test. Intragroup analysis of the follow-up PTI results revealed that both groups experienced a significant improvement in activity scores (p < 0.001) compared with their previous PTI results and that group I had significantly better scores for two other PTI traits-cyclothymia (mood swings) and depressive tendency (p < 0.05); neither group showed a significant improvement in dominance scores. Intergroup comparisons revealed that group I's activity and depressive tendency scores were significantly better than those of group II; there was no significant difference between the two groups in cyclothymia and dominance scores. Finally, comparison of results by sex, regardless of group, revealed that men had a significantly higher score for dominance and women had significantly higher scores for depressive tendency, emotional instability, introversion, and social desirability. We conclude that a preoperative personality analysis should be carried out in all patients scheduled for laryngectomy to identify those with personality problems that might benefit from psychological counseling. Correction of these problems should help in the physical, mental, vocational, and social rehabilitation of these patients.
