Temporalis fascia has become the most widely used graft for tympanoplasty, as it is strong, durable, and easy to procure and handle. However, the type of temporalis fascia graft to use (i.e. dry or wet) remains controversial. The present review aimed to evaluate the success rates of dry and wet temporalis fascia grafts in type I underlay tympanoplasty.

A literature search was performed, using PubMed up to August 2016, to identify all studies of dry and wet temporalis fascia grafts in type I underlay tympanoplasty. The initial search using the key words ‘temporalis fascia’ and ‘tympanoplasty’ identified 130 articles; these were screened by reviewing the titles or abstracts based on the inclusion and exclusion criteria. Ultimately, this review included seven articles.

A dry or wet temporalis fascia graft did not affect the outcome of type I underlay tympanoplasty. However, using wet temporalis fascia could shorten the duration of surgery in type I underlay tympanoplasty. Concerns that the fibroblast count of temporalis fascia may beneficially affect success rate have not been substantiated in clinical reports thus far.

Although benign paroxysmal positional vertigo and endolymphatic hydrops are considered to be distinct diagnoses, a minority of vertiginous patients exhibit features of both conditions. This coincidence has been reported previously in the literature, and is reviewed here in terms of possible aetiology.

A new hypothesis to account for both conditions is offered, implicating free-floating degenerating debris from the otolithic apparatus. It is postulated that the gelatinous/proteinaceous component may account for an osmotically induced hydrops, while the calcified fragments may induce positional vertigo.

To review the history of moist therapy used to regenerate traumatic tympanic membrane perforations.

Literature review.

The literature on topical agents used to treat traumatic tympanic membrane perforations was reviewed, and the advantages and disadvantages of moist therapy were analysed.

A total of 76 studies were included in the analysis. Topical applications of certain agents (e.g. growth factors, Ofloxacin Otic Solution, and insulin solutions) to the moist edges of traumatic tympanic membrane perforations shortened closure times and improved closure rates.

Dry tympanic membrane perforation edges may be associated with crust formation and centrifugal migration, delaying perforation closure. On the contrary, moist edges inhibit necrosis at the perforation margins, stimulate proliferation of granulation tissue and aid eardrum healing. Thus, moist perforation margins upon topical application of solutions of appropriate agents aid the regeneration of traumatic tympanic membrane perforations.

Wound healing after endoscopic sinus surgery may result in adhesion formation. Hyaluronic acid may prevent synechiae development. A systematic review was performed to evaluate the current evidence on the clinical efficacy of hyaluronic acid applied to the nasal cavity after sinus surgery.

Studies using hyaluronic acid as an adjunct treatment following endoscopic sinus surgery for chronic rhinosinusitis were identified. The primary outcome was adhesion formation rates. A meta-analysis was performed on adhesion event frequency. Secondary outcome measures included other endoscopic findings and patient-reported outcomes.

Thirteen studies (501 patients) met the selection criteria. A meta-analysis of adhesion formation frequency on endoscopy demonstrated a lower risk ratio in the hyaluronic acid intervention group (42 out of 283 cases) compared to the control group (81 out of 282) of 0.52 (95 per cent confidence interval = 0.37–0.72). Hyaluronic acid use was not associated with any significant adverse events.

Hyaluronic acid appears to be clinically safe and well tolerated, and may be useful in the early stages after sinus surgery to limit adhesion rate. Further research, including larger randomised controlled trials, is required to evaluate patient- and clinician-reported outcomes of hyaluronic acid post sinus surgery.

To review research addressing the polymicrobial aetiology of otitis media in Indigenous Australian children in order to identify research gaps and inform best practice in effective prevention strategies and therapeutic interventions.

Literature review.

Studies of aspirated middle-ear fluid represented a minor component of the literature reviewed. Most studies relied upon specimens from middle-ear discharge or the nasopharynx. Culture-based middle-ear discharge studies have found that non-typeable Haemophilus influenzae and Streptococcus pneumoniae predominate, with Moraxella catarrhalis, Staphylococcus aureus and Streptococcus pyogenes isolated in a lower proportion of samples. Alloiococcus otitidis was detected in a number of studies; however, its role in otitis media pathogenesis remains controversial. Nasopharyngeal colonisation is a risk factor for otitis media in Indigenous infants, and bacterial load of otopathogens in the nasopharynx can predict the ear state of Indigenous children.

Most studies have used culture-based methods and specimens from middle-ear discharge or the nasopharynx. Findings from these studies are consistent with international literature, but reliance on culture may incorrectly characterise the microbiology of this condition. Advances in genomic technologies are now providing microbiologists with the ability to analyse the entire mixed bacterial communities (‘microbiomes’) of samples obtained from Indigenous children with otitis media.

To search for studies on tongue–lip adhesion and tongue repositioning used as isolated treatments for obstructive sleep apnoea in children with Pierre Robin sequence.

A systematic literature search of PubMed/Medline and three additional databases, from inception through to 8 July 2016, was performed by two authors.

Seven studies with 90 patients (59 tongue–lip adhesion and 31 tongue repositioning patients) met the inclusion criteria. Tongue–lip adhesion reduced the mean (± standard deviation) apnoea/hypopnoea index from 30.8 ± 22.3 to 15.4 ± 18.9 events per hour (50 per cent reduction). The apnoea/hypopnoea index mean difference for tongue–lip adhesion was −15.28 events per hour (95 per cent confidence interval = −30.70 to 0.15; p = 0.05). Tongue–lip adhesion improved the lowest oxygen saturation from 75.8 ± 6.8 to 84.4 ± 7.3 per cent. Tongue repositioning reduced the apnoea/hypopnoea index from 46.5 to 17.4 events per hour (62.6 per cent reduction). Tongue repositioning improved the mean oxygen saturation from 90.8 ± 1.2 to 95.0 ± 0.5 per cent.

Tongue–lip adhesion and tongue repositioning can improve apnoea/hypopnoea index and oxygenation parameters in children with Pierre Robin sequence and obstructive sleep apnoea.
