The purpose of the study was to perform a systematic review and meta-analysis of the literature to compare the efficacy (and other postoperative outcomes) of nonabsorbable versus absorbable nasal packing after functional endoscopic sinus surgery (FESS) for the treatment of chronic rhinosinusitis. Studies were considered for inclusion if they were published in English language, were randomized clinical trials, and reported on outcomes following postoperative synechia. The primary outcome for meta-analysis was the incidence of postoperative synechia; pooled odds ratios (ORs) and 95 % confidence intervals (CIs) were calculated using fixed-effects models. Five studies, involving 241 nasal cavities in each treatment group, were included in the systematic review. The prevalence of synechia ranged from 4.6 to 8.0 % in the absorbable groups and from 8.0 to 35.7 % in the nonabsorbable groups. Postoperative bleeding was lower in the absorbable groups, whereas there was no clear finding regarding postoperative pain. Postoperative edema was generally similar between groups. There were no consistent findings regarding bleeding and pain on packing removal. Two studies using the same type of packing material were included in the meta-analysis. The combined OR (0.33, 95 % CI 0.04–2.78) for postoperative synechia did not significantly favor (P = 0.308) absorbable packing over nonabsorbable packing. Although there is some evidence in the available literature that absorbable nasal packing may provide superior outcomes to nonabsorbable packing after FESS, the lack of homogeneity between studies makes definitive conclusions impossible. Further randomized clinical trials are needed to compare the efficacy of different types of absorbable nasal packing for preventing synechia after FESS.

We determined temporal bone anatomy in patients with unilateral attic cholesteatoma. We compared the affected and normal ears of ten patients with unilateral attic cholesteatoma using three-dimensionally reconstructed high-resolution computed tomography images of the temporal bone. We determined the eustachian tube angle, eustachian tube length, sizes of the tympanic orifice of the eustachian tube, the pars flaccida, and the mastoid cavity, and distances of the pars flaccida and the tympanic orifice of the eustachian tube from the epitympanic roof. No significant differences were found between the normal and affected ears with regard to the size of the eustachian tube orifice, eustachian tube length or distances of the pars flaccida and the tympanic orifice of the eustachian tube from the epitympanic roof. By contrast, the mastoid cavity and the eustachian tube angle were significantly larger in the normal ears than in the affected ears [mean, 6.99 cm(3) (S.D.,4.9 cm(3)) vs. 1.28 cm(3) (0.81 cm(3)) and 16.7° (4.12°) vs. 13.89° (5.30°), respectively]. The pars flaccida was significantly smaller in the normal ears [1.07 cm (0.31 cm)] than in the affected ears [2.19 cm (0.77 cm)]. The inherent anatomy of the eustachian tube may be particularly important in the formation of attic cholesteatomas.

Nontuberculous mycobacterial otomastoiditis is rare and can be easily confused with various different forms of otitis media. We describe the case of a 50-year-old woman who presented with left-sided chronic otitis media that had persisted for more than 1 year. It was not eradicated by standard antimicrobial therapy and surgical debridement. After appropriate antibiotic therapy for nontuberculous mycobacteria was added to the therapeutic regimen, the patient improved significantly and the lesion had healed by 6 months. Based on our experience with this case, we conclude that early bacterial culture and staining for acid-fast bacilli in ear drainage material or granulation tissue should be performed when standard antimicrobial therapy fails to eradicate chronic otitis media of an undetermined origin that is accompanied by granulation tissue over the external auditory canal or middle ear. Polymerase chain reaction testing is also effective for rapid diagnosis. Surgical debridement and removal of the foreign body can successfully treat nontuberculous mycobacterial otomastoiditis only when effective antimicrobial therapy is also administered.
