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

Contralateral labyrinthine concussion in temporal bone fractures

In this case presentation, three cases of labyrinthine concussion in the opposite ears of patients who had unilateral traumatic temporal bone fractures with facial paralysis are reported. The first patient was a 30-year-old male who had a right-sided longitudinal temporal bone fracture and labyrinthine concussion showing pure sensorineural hearing loss with a characteristic notch of 60 dB at 4000 Hz on the left side. The second patient was a 42-year-old male who had a right-sided traumatic facial paralysis owing to a mixed-type temporal bone fracture and labyrinthine concussion, demonstrating pure sensorineural hearing loss reaching its peak of 50 dB at 4000 Hz on the left. The third patient was a 19-year-old male who had a left-sided mixed-type temporal bone fracture and a right labyrinthine concussion exhibiting pure sensorineural hearing loss reaching 60 dB at 4000 Hz. For their facial paralyses, all three patients underwent middle cranial fossa or combined approach operations. The labyrinthine concussion in these patients was managed expectantly. At their 1-year follow-up, it was observed that the hearing loss owing to labyrinthine concussion persisted. Although labyrinthine concussion is not a rare complication of head injuries, it has rarely been reported in the medical literature. The main symptoms of labyrinthine concussion are hearing loss, tinnitus, and dizziness. The diagnosis mainly relies on audiometric tests, which reveal characteristic tracings reminiscent of acoustic trauma

Sectioning the sensory auricular branch of the facial nerve to treat recalcitrant otalgia

To present a new surgical approach to treat idiopathic neuralgia of the sensory auricular branch of the facial nerve. : Three patients with chronic ear pain resistant to medical therapy. Sectioning of the sensory auricular branch of the facial nerve along its course at the posterior wall of the external auditory canal by a retroauricular mastoidectomy approach. Resolution of otalgia. All the patients were relieved of their pain at their first follow-up visit, and they have remained symptom-free. The patients were followed at least for 1 year. The surgical treatment of idiopathic otalgia should be reserved for patients in whom medical treatment has failed. Finding the exact location of the ear pain is of utmost importance for a favorable outcome after surgery. If the origin of the otalgia is found to be the sensory auricular branch of the facial nerve, the section of this nerve offers favorable outcomes with no morbidity
