Article Abstract
Background: Facial sensory nerves play vital roles in daily functions like self-protection, facial expressions, speaking, and eating. Severing the infraorbital nerve (ION) during partial maxillectomy via the Weber-Ferguson incision can lead to sensory disturbances. This study presents immediate ION reconstruction using artificial nerve conduits and its short-term outcomes.
Methods: This retrospective study included three patients (mean age: 67.0 years) undergoing immediate ION reconstruction after partial maxillectomy via the Weber-Ferguson incision. Sensory recovery was evaluated using the Semmes-Weinstein and two-point discrimination (2PD) tests. A reference group of five patients who underwent total maxillectomy without ION reconstruction was also assessed.
Results: No postoperative complications were observed during the 15.3-month follow-up. Sensory recovery varied among patients, with one achieving normal perception at 24 months, another showing diminished light touch at 13 months, and the third experiencing diminished protective sensation at 7 months postoperatively. In comparison, the reference group showed lower sensory recovery. Two patients showed improvements in 2PD test results at 24 and 13 months, whereas one showed no recovery at 7 months. No patients in the reference group showed improvement.
Conclusion: Immediate ION reconstruction using artificial nerve conduits after partial maxillectomy appears feasible, as evidenced by acceptable sensory recovery in the short term.

Actinomycotic osteomyelitis in the maxilla is a rare complication, particularly in diabetic patients following dengue infection. Actinomycosis, caused by , typically arises in immunocompromised hosts, with dengue-induced immune dysregulation and diabetes contributing to its pathogenesis. This case report describes a 42-year-old diabetic male presenting with oroantral communication, loose posterior maxillary teeth, and persistent pus discharge 20 days postdengue.

Introduction: Patient-specific implants(psi) manufactured using 3D printing and CAD-CAM technology have played a major role in the rehabilitation of complex maxillofacial defects caused due to mucormycosis also known as the black fungus, which is a rare fungal infection that originates as a result of inhalation of its filamentous hyphal form.
Methods: In this unique case series, we report six cases of complex maxillofacial defects caused due to mucormycosis managed by patient-specific implants, in Hyderabad. These patients had undergone either partial or total maxillectomy after being affected by mucormycosis and were disease-free clinically and radiographically for 6 or more months post-resection and were rehabilitated using patient-specific zygoma implants.

Objectives: This study aimed to describe the use of cerclage wires with or without polypropylene mesh for the reconstruction of maxillectomies with or without concurrent orbitectomy and report the surgical outcomes.
Materials And Methods: Dogs presented for resection of a maxillary/orbital neoplasia and reconstruction were retrospectively enrolled. Data retrieved from medical records included signalment, tumour site and size, type of maxillectomy and reconstruction, results of histological examination, surgical time and surgical complications.
