Objectives: Facial paralysis is a devastating yet frequent complication of skull base surgery, significantly impacting quality of life through functional impairments and psychosocial consequences. Management is complex and requires an individualized approach based on duration of paralysis, etiology and extent of nerve injury, overall prognosis, and rehabilitative goals. This review provides a comprehensive overview of current strategies for managing post-skull base surgery facial paralysis. Methods: A narrative review of the literature was performed, analyzing surgical reanimation techniques (nerve grafting, nerve transfers, regional and free muscle transfers), static procedures for facial symmetry and ocular protection, and non-surgical interventions such as physical therapy, botulinum toxin injections, and psychological support. Key criteria guiding treatment selection, including muscle viability and timing since injury, were examined. Results: Dynamic surgical approaches remain central to restoring movement. Nerve grafting and transfers are effective when viable musculature is present, whereas regional or free muscle transfers are required in long-standing paralysis with irreversible atrophy. Static procedures provide adjunctive improvements in resting symmetry and eye protection. Non-surgical strategies, including rehabilitation therapy and botulinum toxin, enhance functional outcomes and reduce synkinesis. Psychological counseling addresses the profound emotional burden associated with facial disfigurement. Across modalities, individualized treatment planning is crucial. Conclusions: Management of facial paralysis after skull base surgery demands a multidisciplinary, patient-centered approach. Combining surgical and non-surgical interventions optimizes functional and aesthetic outcomes, helping restore both facial movement and psychosocial well-being.

Objective To systematically review the published cases of bilateral facial palsy (BFP) to gather evidence on the clinical assessment and management of this pathology. Methods Following PRISMA statement recommendations, 338 abstracts were screened independently by two authors. Inclusion criteria were research articles of human patients affected by BFP, either central or peripheral; English, Italian, French or Spanish language; availability of the abstract, while exclusion criteria were topics unrelated to FP, and mention of unilateral or congenital FP. Only full-text articles reporting the diagnostic work-up, the management, and the prognosis of the BFP considered for further specific data analysis. Results A total of 143 articles were included, resulting a total of 326 patients with a mean age of 36 years. The most common type of the paralysis was peripheral (91.7%), and the autoimmune disease was the most frequent aetiology (31.3%). The mean time of onset after first symptoms was 12 days and most patients presented with a grade higher than III. Associated symptoms in idiopathic BFP were mostly non-specific. The most frequently positive laboratory exams were cerebrospinal fluid analysis, autoimmune screening and peripheral blood smear, and the most performed imaging was MRI. Most patients (74%) underwent exclusive medical treatment, while a minority were selected for a surgical or combined approach. Finally, in more than half of cases a complete bilateral recovery (60.3%) was achieved. Conclusions BFP is a disabling condition. If a correct diagnosis is formulated, possibilities to recover are elevated and directly correlated to the administration of an adequate treatment.

Objectives Among the complications of parotid surgery, facial palsy is frequent and burdened by high functional and social impact for the patient. There are few data on the efficacy of facial neuromuscular retraining (FNR) in patients with facial palsy after parotid surgery, and no data exist on its impact in timing and extent of recovery. Material and methods A retrospective study was conducted on patients undergoing FN sparing parotid surgery and suffering from postoperative facial palsy. Among 400 patients undergoing surgery between July 2016 and May 2023, those with the preservation of the FN and onset of facial palsy were selected. Nerve function was evaluated during 2 years follow up using the House-Brackman (H&Bs) and Sunnybrook scales (SBs). Results A total of 46 patients undergoing partial or total parotidectomy were included. At discharge 18 patients (39,1%) had IV to VI grade paralysis according to the H&Bs and the mean SBs value was 54. At 2 and 6 months after surgery, the average value of Sunnybrook increased to 76.5 and 95.4 respectively. After 12 months no patients with IV to VI grade paralysis were represent in our cohort. Two years after surgery, only five patients (10.9%) had persistent grade II paralysis according to HBs. Conclusions Our study supports the efficacy of FNR in the rehabilitation of facial paralysis after nerve-sparing parotidectomy. The greater functional improvement is achieved within the first 6 months of rehabilitation. A significant improvement is detected still after 18 months, supporting the importance of long rehabilitation for patients without complete recovery after the first year.

Purpose A variety of lesions could arise from the GG area, or extend into this region from adjacent sites. The management of perigeniculate lesions includes observation, surgery, and radiation, according to the nature, the size of the lesion, and the accompanying symptoms. Preliminary experiences on the exclusive transcanal endoscopic approach to the GG area have shown safety and feasibility avoiding of any postauricular incision, or brain manipulation. The experience from two referral centers on patients treated for a GG lesion with a totally endoscopic approach is herein reported. Methods Data about patients who underwent exclusive endoscopic approach to the GG area at the Otolaryngology Departments of the University Hospitals of Modena and Bologna between May 2017 and February 2022 were retrospectively collected. Results The total number of patients included in our study was 11. 10 patients (91%) had progressive unilateral facial paralysis and 1 patient (11%) presented with chronic otorrhea. The mean largest diameter of the treated lesions was of 8 mm. The resection was extended to the fundus of the IAC in 2 patients ( expanded approach ). The remaining 9 patients (82%) underwent partial ossicular replacement prosthesis (PORP). No major complications occurred. Facial nerve outcomes were good in all patients and the mean ABG worsened from 12 dB pre-operatively to 22 dB post-operatively. Conclusions The exclusively endoscopic approach to GG lesions represents a viable alternative to traditional microscopic approaches and may be included in the armamentarium of ear surgeons.

Background: Oncological surgery of the parotid gland or of the temporal bone may require the contemporary sacrifice of the facial nerve (FN). In such cases, the immediate repair of the sacrificed FN is recommended. The aim of this study is to evaluate the impact of facial rehabilitation (FR) and, secondarily, of post-operative radiotherapy (PORT) on the FN outcome after FN sacrifice and reconstruction via cable graft. Methods: This is a multicentric retrospective study including patients affected by malignant tumors whose surgical excision required FN sacrifice and contextual FN reconstruction with a cable graft. Other FN reconstruction techniques were excluded. FN function was assessed using both House–Brackmann and Sunnybrook grading systems. Results: A total of 28 patients were included. Most of the patients underwent a total parotidectomy. The greater auricular nerve was the main donor for cable graft. FR and PORT were performed in 22 and 15 patients, respectively. In particular, 20 patients underwent neuro-muscular retraining (NMR). Patients who underwent FR had better FN outcomes compared to those who did not (p = 0.02 at 12 months and p = 0.0002 at 24 months). In contrast, there was no statistically significant difference between patients who underwent PORT and those who did not (p > 0.05). Pre-operative FN palsy is a risk factor of worse FN function outcomes after cable graft. Conclusions: Our study, even though it was limited to only 28 cases, may demonstrate that cable graft failure is not due to PORT, as widely believed among clinicians, but to the absence of a rehabilitation program. Moreover, we suggest that the key to obtaining the best possible FN function results after FN sacrifice is the association of a technically correct FN reconstruction with a proper and targeted FR.
