BACKGROUND AND OBJECTIVE: No consensus has yet been reached with regard to the link between otitis media with effusion (OME), hearing loss, and language development in children with cleft palate. The objective of this study was to address the effectiveness of ventilation tube insertion (VTI) for OME in children with cleft palate. METHODS:A dual review process was used to assess eligible studies drawn from PubMed, Medline via Ovid, Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, and reference lists between 1948 and November 2013. Potentially relevant papers were selected according to the full text of the articles. Relevant data were extracted onto a data extraction sheet. RESULTS:Nine high-or moderate-quality cohort studies were included in this study. VTI was administered in 38% to 53% of the OME cases, and more severe cases appeared more likely to undergo VTI. Compared with conservative forms of management (eg, watchful waiting), VTI has been shown to be beneficial to the recovery of hearing in children with cleft palate and OME. A growing body of evidence demonstrates the benefits of VTI in the development of speech and language in children with cleft palate and OME. These children face a higher risk of complications than those undergoing conservative treatments, the most common of which are eardrum retraction and tympanosclerosis, with an incidence of ∼11% to 37%. CONCLUSIONS:This review provides evidence-based information related to the selection of treatment for OME in children with cleft palate. Additional randomized controlled trials are required to obtain bias-resistant evidence capable of reliably guiding treatment decisions. The conclusions in this review are based on underpowered cohort studies and very-low-strength evidence.

Exactly how speech perception and tinnitus perception are related remains unclear. This study investigated how tinnitus alone affects speech perception and the relationship between speech perception, tinnitus loudness, and tinnitus disability. The Mandarin Speech Perception in Noise Test (MSPIN), Tinnitus Loudness Scaling (TLS), and Tinnitus Handicap Inventory (THI) were utilized to assess 20 tinnitus patients with normal hearing. The tinnitus group had a significantly lower MSPIN score than the control group (p < 0.01). TLS and THI scores were strongly correlated (r²: 0.534∼0.627, p < 0.05). Correlations between MSPIN and TLS or THI scores were not significant. Tinnitus loudness correlated well with tinnitus-related disability. Neither tinnitus loudness nor disability was strongly correlated with speech perception. In noisy environments, tinnitus sufferers had significantly poorer ability to recognize speech than control subjects.

Directive counseling and sound therapy have been reported to effectively alleviate tinnitus suffering. Without objective evaluation, researchers doubt the real effect of sound therapy. This study was designed to evaluate the frequency and intensity of the theoretical ‘mixing point’ (MP) in sound therapy and to investigate its relationship with the minimal masking level (MML) of tinnitus. The tinnitus tones of 133 patients were successfully matched in frequency (dominant in 4–10 kHz) and loudness (83.09 ± 12.04 dB) using a psychoacoustic matching protocol and a newly designed tinnitus evaluation system. The matching rate was 83%. The relationship between the MP and MML is described by a linear regression equation: MP = 0.90 × MML + 1.98 (r² = 0.82, p < 0.0001). The results of matching and correlation analysis confirmed the consistency of the MP in sound therapy. The psychoacoustic characteristics of tinnitus can be objectively evaluated with our matching protocol and evaluation system.

In total, 1205 cleft children were collected, with 151 in the VTI only group and 1054 in the VTI + palatoplasty group. Ventilation tube re-insertion rates were significantly lower in the VTI + palatoplasty group (p = 0.002). The cumulative re-insertion rates also showed a significant difference (p = 0.001). When compared to the VTI only group, the adjusted hazard ratio was 0.528 in the VTI + palatoplasty group (p = 0.001).

Among the study population, 129 patients underwent revision surgery during a 5.5 ± 1.5 year follow-up period. A univariate logistic regression analysis showed that the re-operation rate was significantly higher in patients under 18 years of age, those with mastoiditis, disorders of external ear, treatment by surgeons of 50-64 years of age, use of a very high volume surgeon, and combined surgery with mastoidectomy. A multivariate analysis further limited the re-operation risk factors to younger patients, those with mastoiditis, external ear disorders, treatment by older surgeons, and concomitant mastoidectomy.
