The infraorbital nerve is responsible for the sensory innervation of the lower eyelid, the lateral nose, the cheek, the upper lip, and the maxillary teeth. It passes along the infraorbital canal, which runs superior to the maxillary sinus. Dehiscence of the infraorbital canal and its ectopic course in the maxillary sinus is a rare variation. A nerve with these variations may be affected by pathologies in the maxillary sinus and this may constitute a rare cause of facial pain. In this report, we present the clinical symptoms of a 29-year-old male patient who had an infraorbital nerve with an ectopic course and dehiscence in light of the literature.

Lipomas are benign neoplasms of mesenchymal origin. Although they are frequently seen in other parts of the body, they are rare in the oral cavity. In the oral cavity, they most often develop from buccal mucosa. They tend to grow slowly, so they may remain asymptomatic for a long time and go unnoticed. Lipomas in the oral cavity may cause deterioration in chewing-speaking and esthetic problems over time, depending on the increase in their size. The most reliable imaging method for differential diagnosis is magnetic resonance imaging. Complete excision of the lipoma is essential for treatment. In this study, a case of an unusual oral lipoma, causing nutrition-speaking difficulties in a geriatric male patient is presented.

Background: Studies about inflammation indices are becoming increasingly common. Inflammation is thought to play an important role in the aetiopathogenesis of sudden sensorineural hearing loss. Aim: In this study, we aimed to compare sudden sensorineural hearing loss patients and patients in a control group in terms of pan-immune-inflammation value and lymphocyte-monocyte ratio and to determine the relationship of these indices with sudden sensorineural hearing loss. Methods: The research was designed as a retrospective, case-control study. The archival records of patients diagnosed with sudden sensorineural hearing loss between 1 January 2018 and 1 May 2023 were scanned. Within the scope of the study, age, gender, amount of hearing loss, hearing loss accompanied by vertiginous symptoms, hearing loss accompanied by tinnitus, full blood count results, pan-immune-inflammation value and lymphocyte-monocyte ratio were analysed between the groups. Statistical analyses were performed using the independent samples t -test, Chi-square test and Pearson correlation analysis. Results: Leukocyte, neutrophil, platelet and pan-immune-inflammation values were found to be significantly higher in patients with sudden sensorineural hearing loss ( P values: 0.023, <0.001, 0.010, <0.001, respectively). Lymphocyte and monocyte values were significantly lower ( P values: <0.001, 0.006, respectively). There was no significant difference in terms of lymphocyte-monocyte ratio ( P = 0.455). There was no relationship between tinnitus, vertiginous symptoms and blood parameters. There was a positive correlation between neutrophil value and the amount of hearing loss ( P = 0.036). Conclusion: In our study, the pan-immune-inflammation value was significantly higher in sudden sensorineural hearing loss patients. A statistically significant relationship was detected between high neutrophil values and the amount of hearing loss. These results can be evaluated on the basis of the inflammation-ischaemia relationship in the aetiopathogenesis of sudden sensorineural hearing loss.
