“…Cases of depression, suicidal thoughts, self-biting, dribbling, and retention of food on the chin in public have also been observed 1,2 . Trigeminal nerve injuries can be caused by extraction of inferior third molars, dental implant surgery, ostectomy, incision, orthognathic surgery, maxillofacial trauma, surgery for oral pathology, edema and postsurgical infection, and even anesthetic injection [3][4][5][6] . The highest prevalence of trigeminal nerve injuries in oral surgery are the terminal branches of the mandibular nerve, the inferior alveolar nerve (IAN) and its mental branch, and the lingual nerve (LN) 7 .…”

It is essential to maintain the alveolar bone ridge to ensure the success of implant therapy. Platelet-rich fibrin (PRF) may benefit bone repair, but its quantitative microscopic results are still inconclusive. The aim of this study was to histomorphometrically analyze human dental alveoli after extraction treated with autologous fibrin, biphasic calcium phosphate or sticky bone. The sample consisted of healthy adult volunteer patients, with clinical and tomographic indication for single post-extraction graft of upper premolars for maintenance of the alveolar ridge and subsequent implantation. The 10 remaining patients in the study were divided into three groups according to the type of filling used in the dental socket: autologous PRF plug covered by a PRF membrane (G1), PRF associated with an alloplastic graft based on hydroxyapatite with beta tricalcium phosphate covered by a collagen membrane (G2) or alloplastic graft based on beta tricalcium phosphate covered by collagen membrane (control). After 8 months, bone biopsies were performed at the grafted sites and the patients underwent implant-prosthetic rehabilitation. Paraffin-embedded tissue blocks were routinely processed and sectionsfrom different depths were mounted in 3 slides and stained with HE. The histomorphometric evaluation analyzed 30 photomicrographs per block, quantifying the percentage presence of newly formed bone, connective tissue and remaining biomaterial using the ImageJ software. Parametric data enabled intergroup comparisons using ANOVA and Tukey’s post-hoc test for multiple comparison with statistical significance of 5% (p<0.05), with normality of the 3 groups by the Jarque-Bera test (p>0.05). There was a higher mean of newly formed bone in G1 (68.83%) compared to G2 (35.69%) and control (16.28%). There was greater presence of connective tissue in the control (61.56%). Remaining biomaterial was higher in G2 (15.75%), but did not differ statistically from the control. Bone regeneration obtained with PRF alone or sticky bone suggests the efficacy of these therapies, encouraging the clinical use of this blood concentrate in dental procedures.

“…2 The trigeminal nerve and its branches are among the most susceptible nerves, and the consequences of trigeminal nerve injury can be extremely disturbing. 3 Trigeminal sensory neuropathy (TSN) is characterized by diminished/exaggerated sensations along the distribution of trigeminal branches, causing numbness (hypoesthesia) or pain (hyperalgesia) in the corresponding area of the face/nose/mouth. It has been shown that surgery for idiopathic trigeminal neuralgia (ITN), 4-7 meningiomas, 8 and vestibular schwannomas (VS) 9-11 was associated with increased risk of TSN.…”

BACKGROUND: Trigeminal sensory neuropathy, characterized by diminished or exaggerated/painful sensation along the distribution of trigeminal branches, is one of the complications after skull base surgery. These procedures can also affect chemosensory functions and compromise the patients' quality of life. OBJECTIVE: To examine those postoperative complications in chemosensory and facial cutaneous sensory functions as well as their interaction. METHODS: A total of 61 patients being operated for various pathologies in the vicinity of trigeminal pathway (17 with trigeminal neuralgia, 20 with meningiomas, and 24 with vestibular schwannomas) and 50 healthy controls were enrolled in this case-control study. Postoperative trigeminal neuropathic symptoms were evaluated. The olfactory, gustatory, and intranasal trigeminal functions were assessed using the Sniffin' Stick olfactory test, lateralized taste strip test, and the lateralized intranasal trigeminal CO 2 detection thresholds, respectively. RESULTS: Patients with trigeminal neuralgia and meningioma had relatively decreased olfactory function, whereas those with vestibular schwannoma had a relative decrease in taste function. As for the relationship between the distribution of trigeminal neuropathy and chemosensory dysfunction, we found that V3 involvement predicted lower sidespecific taste function. In addition, V2/V3 involvement predicted relatively lower sidespecific intranasal trigeminal function. CONCLUSION: The present results suggest a differential involvement of the chemical senses in relation to the site and pathology of the lesions after surgery. The presence of trigeminal neuropathy is associated with taste and intranasal trigeminal dysfunction. The results serve as a basis for consultation regarding outcome prediction and patient education.
