Purpose: This study aimed to verify the low complication rates (0% to 11%) previously reported in cranial reconstruction using hard-tissue replacement patient-matched implant (HTR-PMI).
Patients And Methods: A 3-year multidisciplinary experience involving 21 patients undergoing HTR-PMI reconstruction of large cranial defects was reviewed. Complications were defined as implant exposure, implant infection, or soft-tissue infection.
Results: A statistically higher rate of complications was observed, compared with previous series (P= .043). We also determined whether previous bone infection, a history of diabetes, or smoking were risk factors for the development of complications. Diabetes, smoking, and pre-existing bone/implant infections were not significant risk factors for HTR-PMI failure. The higher rate of complications can be partially attributed to a diverse and complicated patient population, with multiple comorbid conditions and various indications for HTR-PMI reconstruction. In particular, decompressive craniectomies in trauma patients can be risky indications for the use of HTR-PMI.
Conclusion: Larger studies are suggested to verify our findings.

Purpose: The escalating number of endoscopic skull base procedures necessitates exploring additional materials to reduce postoperative cerebrospinal fluid (CSF) leaks in revision or staged surgeries. This study evaluates the effectiveness of reused nasoseptal flaps (NSFs) in such clinical scenarios.
Methods: A retrospective review was conducted on patients who previously underwent surgery involving NSFs and later had revision or secondary skull base surgeries via endoscopic endonasal approaches (EEAs) at a tertiary medical center.

Introduction: Intensive research is dedicated to the development of novel biomaterials and medical devices to be used as grafts in reconstructive surgery, with the purpose of enhancing their therapeutic effectiveness, safety, and durability. A variety of biomaterials, from autologous bone to polymethylmetacrylate, polyether ether ketone, titanium, and calcium-based ceramics are used in cranioplasty. Porous hydroxyapatite (PHA) is reported as a possible material for bone reconstruction, with good signs of biocompatibility, osteoconductive and osteointegrative properties.

: Autologous bone grafting is the first choice for reconstructive surgery in bone defects due to trauma or malignant tumors. However, there is an increasing demand for minimally invasive alternatives involving bone regeneration using artificial materials. Biomimetic materials that replicate the body's microscopic structure, such as Cellnest, are gaining attention.

Fibrous dysplasia is an uncommon bone disorder affecting various parts of the skeleton, often affecting facial and cranial bones. In this case, a 10-year-old patient was diagnosed with fibrous dysplasia of the ethmoid sinus at an early age. The patient has experienced nasal congestion, snores, and worsening nasal patency since 2019.

Objective: To evaluate the clinical outcomes and define the indications for a one-stage mandibular reconstruction technique that combines iliac bone flaps with immediate implant-based dentures, and to assess both the accuracy of surgical planning and the long-term success of the procedure.
Methods: A total of ten patients underwent the procedure at Peking University Hospital of Stomatology between June 2020 and August 2023. The preoperative biopsy pathology of all the patients confirmed a benign tumor.
