The Healing Effects of Autologous Mucosal Grafts in Experimentally Injured Rabbit Maxillary Sinuses.

OBJECTIVES: Healing processes of the nose and paranasal sinuses are quite complex, and poorly understood. In this study, we aimed to compare the effect of mucosal autologous grafts on the degenerated rabbit maxillary sinus mucosa with spontaneous wound healing. It is hypothesized that mucosal grafts will enhance ciliogenesis and improve the morphology of regenerated cilia. METHODS: Ten female New Zealand rabbits were included in the study. They underwent external maxillary sinus surgery through a transcutaneous approach. A total of 20 maxillary sinuses were randomly divided into 2 groups: 'spontaneous healing group' and 'autologous graft group.' The animals were sacrificed at the 14th day after the surgery. Scanning electron microscope (SEM), and light microscope were used for the evaluation. RESULTS: Cellular composition of the graft group is better than the spontaneous healing group. The graft group had larger areas covered with ciliary epithelium than the spontaneous healing group, and the mean length of the cilias were also longer. Additionally, there were wider cilia with abnormal morphology areas in the spontaneous healing group. CONCLUSION: In our opinion, covering of the denuded areas with a graft improves re-epithelization, and may prevent the early complications after sinus surgeries.

Scrupulosity and obsessive compulsive disorder: the cognitive perspective in Islamic sources.

A moral/religious subtype of obsessive compulsive disorder has been termed as scrupulosity by mental health professionals. Since ultimate feared consequence in scrupulous individuals is religious or moral in nature, it also presents interesting and difficult issue for religious authorities. This article focuses on various aspects of scrupulosity that have until now been poorly conceptualized in Islamic world and provides a conceptual cognitive framework and analysis of scrupulosity according to Islamic sources.

[Juvenile angiofibroma originating from the sphenoid sinus: a case report]. / Sfenoid sinüs kaynakli juvenil anjiyofibrom: Olgu sunumu.

Angiofibromas are histologically benign, but unencapsulated and highly vascular tumors with a potential of local destructive effect. Angiofibromas predominantly originate from the posterolateral wall of the nasopharynx. Extranasopharyngeal angiofibromas are extremely rare and mostly seen in maxillary sinus and ethmoid sinus. In this article, we report a 21-year-old male case who was admitted with headache and diagnosed with an angiofibroma originating from the sphenoid sinus.
