The Impact of Inferior Turbinate Reduction on Middle Ear Function in Adults With Nasal Obstruction.

Objective This study aims to evaluate the effect of inferior turbinate reduction on middle ear compliance and pressure. Methods A prospective observational study was conducted on 100 patients between 20 and 60 years of age with bilateral nasal obstruction due to inferior turbinate hypertrophy and a normal-looking external and middle ear. The Wilcoxon signed-rank test with a 95% confidence interval was used to compare the middle ear peak compliance and pressure on tympanometry before and one month after the inferior turbinate reduction surgery. Results The mean age was 28.44 ± 8.23 years, with a male/female ratio of 7:3. After surgery, patients with normal compliance increased by 8%, high compliance decreased by 12%, and low compliance increased by 4% in the right ear. High compliance decreased by 2%, normal compliance decreased by 10%, and low compliance increased by 12% in the left ear. Positive tympanometric peak pressure (TPP) increased by 37% and 43% in the right and left ears, respectively. Conclusion After turbinate reduction surgery, the overall tympanometric peak pressure and compliance improved. However, we did not see an obvious improvement in low middle ear compliance. Thus, turbinate reduction surgery might benefit patients with inferior turbinate hypertrophy and associated poor middle ear ventilation.

Treatment algorithm for ameloblastoma.

Ameloblastoma is the second most common benign odontogenic tumour (Shafer et al. 2006) which constitutes 1-3% of all cysts and tumours of jaw, with locally aggressive behaviour, high recurrence rate, and a malignant potential (Chaine et al. 2009). Various treatment algorithms for ameloblastoma have been reported; however, a universally accepted approach remains unsettled and controversial (Chaine et al. 2009). The treatment algorithm to be chosen depends on size (Escande et al. 2009 and Sampson and Pogrel 1999), anatomical location (Feinberg and Steinberg 1996), histologic variant (Philipsen and Reichart 1998), and anatomical involvement (Jackson et al. 1996). In this paper various such treatment modalities which include enucleation and peripheral osteotomy, partial maxillectomy, segmental resection and reconstruction done with fibula graft, and radical resection and reconstruction done with rib graft and their recurrence rate are reviewed with study of five cases.
