Background and Objectives: To evaluate the surgical management and outcomes of lateral semicircular canal fistulas (LSCFs) in patients with middle ear cholesteatoma, focusing on hearing preservation and vestibular function. Materials and Methods: A retrospective study was conducted on nine adult patients diagnosed with LSCFs secondary to cholesteatoma who underwent surgery at a tertiary referral center between 2018 and 2024. The preoperative evaluation included otoscopy, audiometry, vestibular testing (HINTS), and high-resolution CT (HRCT) of the temporal bone. Surgical techniques included canal wall up (CWU) or canal wall down (CWD) mastoidectomy, depending on the disease extent. Cholesteatoma matrix removal from the fistula was performed carefully. Fistula closure involved layered grafts of temporalis fascia, temporalis muscle, and/or gelfoam. The postoperative follow-up included audiometry and vestibular assessments. Results: Nine patients with LSCFs were identified (one Type III, three Type IIb, and four Type I/IIa). Five patients were found to have additional disease complications intraoperatively, including facial nerve involvement and middle fossa dehiscence. Postoperatively, hearing outcomes varied, with some patients experiencing improvement, others demonstrating stable hearing, and some exhibiting further decline, particularly in cases with extensive disease. Vestibular symptoms, including vertigo, generally resolved postoperatively, although some patients required prolonged vestibular rehabilitation. Conclusions: LSCF management in cholesteatoma surgery requires a careful preoperative assessment, meticulous surgical technique, and individualized fistula closure based on the size and type. While hearing preservation remains a challenge, particularly in extensive cases, the “underwater technique” and layered grafting may contribute to minimizing further damage and promoting fistula closure. Vestibular rehabilitation plays a crucial role in managing postoperative balance issues. A long-term follow-up is essential to monitor for recurrence and assess both auditory and vestibular function.

Background: Otogenic lateral sinus thrombosis (OLST) is a rare but potentially life-threatening intracranial complication of middle-ear infection. Despite advances in imaging, antimicrobial therapy and otologic surgery, optimal management—particularly anticoagulation—remains controversial, and no standardized clinical guideline is available. Methods: A structured narrative review was conducted using PubMed for English-language human studies published between 1 January 2015 and 31 January 2025. The search was repeated and documented during revision on 12 May 2026. Four searches were run separately; retrieved records were manually merged, and duplicate record occurrences were removed using PMID. The searches retrieved 83 records before deduplication; after removal of 19 duplicates, 64 unique records remained for title and abstract screening. Single case reports and review articles were excluded from the primary descriptive synthesis. SANRA principles guided review quality and transparency. Seven eligible studies comprising 140 confirmed OLST patients were analyzed descriptively; selected clinically relevant but non-comparable publications were retained for contextual discussion. Results: Most included cohorts were pediatric; one study included both pediatric and adult patients. Clinical presentation was heterogeneous and often attenuated by prior antibiotic exposure. Contrast-enhanced CT was frequently used initially, whereas MRI/MRV was most informative for confirming thrombus extent and follow-up. Broad-spectrum intravenous antibiotics and surgical source control represented core treatment. Anticoagulation was reported in six studies, most often with low molecular weight heparin, but indications and duration varied substantially. Outcomes were generally favorable, although visual impairment, hearing loss, behavioral sequelae and incomplete radiological recanalization were reported. Conclusions: OLST management should be individualized according to disease severity, thrombus extent, septic status, and patient-specific risk factors. Antibiotics and source control are essential, while anticoagulation should be considered selectively. A practical management algorithm is proposed, but prospective multicenter data are needed.

Background and Objectives: Complicated cholesteatomatous otomastoiditis includes a spectrum of inflammatory, suppurative, and destructive lesions affecting the temporal bone and surrounding critical structures, including the dura mater, labyrinth, facial nerve, sigmoid sinus, and skull base. The selection of appropriate surgical techniques and closure materials is decisive for long-term outcomes, functional preservation, and prevention of life-threatening complications. This systematic review and meta-analysis evaluates the evidence base for surgical approaches, intraoperative technologies, and autologous and synthetic closure materials used in the management of iatrogenic and disease-related fistulas in otomastoid surgery. Materials and Methods: A PRISMA 2020-compliant search was conducted across PubMed, Cochrane Library, Embase, and Scopus (2000–2024). The review was registered in PROSPERO (CRD420261370406). After the systematic screening process, 56 eligible studies involving 4218 patients were selected for inclusion. The primary outcome measures analysed were infection rates, fistula recurrence, preservation of function, and long-term integrity of the closure. Limitations include the predominance of observational studies and the absence of prospective registration prior to data extraction. Results: Autologous materials demonstrated consistently low infection rates (<10%) in contaminated operative fields and therefore remain the preferred first-line option for the reconstruction of small to moderate defects. In contrast, synthetic materials exhibited superior mechanical durability in large sterile defects, achieving closure integrity rates of 85–92% at two-year follow-up. Hybrid reconstructive constructs provided the most favourable overall outcomes, with pooled closure integrity reaching 91.6%, suggesting a synergistic advantage when combining biologic and synthetic components. Furthermore, the adjunctive use of combined microscopic–endoscopic surgical techniques was associated with a significant reduction in residual cholesteatoma rates (OR 0.56, 95% CI 0.38–0.82), supporting the growing role of endoscopic assistance in middle ear and mastoid surgery. When biologic closure strategies were appropriately selected according to defect characteristics and contamination status, functional preservation rates exceeded 90–95%, underscoring the importance of tailored reconstructive approaches. Conclusions: The durability of long-term outcomes is most strongly influenced by complete pathological clearance and by the strategic alignment of biomaterial properties with defect dimensions, contamination status, and surrounding anatomical structures. In response to these findings, an evidence-based algorithmic framework is proposed to facilitate rational intraoperative material selection.

A 44‐year‐old man developed otogenic sigmoid sinus thrombosis with cerebellar abscess, hydrocephalus, and recurrent posterior fossa infection. Staged neurosurgical drainage and canal‐wall‐down mastoidectomy achieved source control. Cultures were negative. Anticoagulant exposure was perioperative/early postoperative. Despite persistent venous non‐opacification, he was discharged improved, afebrile, without neurological deficit, and with remitted otoliquorrhea.
