Background: Chondromas are benign tumors with slow growth pattern that may develop along the body. Intracranial chondromas are rare, 0.1 to 0.3% of all intracranial tumors, usually in parasellar region. Few papers reported cavernous sinus chordomas. Case Description: We reported two cases of cavernous sinus chondromas. Two patients presented diplopia, one facial hypoesthesia and one presented extension to the petroclival region. Surgical approaches were frontotemporal combining presigmoid/middle fossa. Literature was reviewed concerning incidence, clinical symptoms, treatment and outcome. Both cases achieved complete tumor resection without postoperative complication. Preoperative deficits improved. Literature review confirms their rarity, clinical symptoms are related to deficits of cranial nerves passing through the cavernous sinus and cure can be achieved through radical surgical removal. Conclusion: Cavernous sinus chondromas are rare benign lesions with insidious growth. Adequate knowledge of cavernous sinus anatomy, microsurgical experience, intraoperative monitoring of cranial nerves and neuronavigation allows radical tumor removal with no additional neurological deficits.

Background Solitary sphenoid sinus pathology is uncommon. The deep position of the sphenoid sinus makes symptoms related to solitary sphenoid sinus pathology non-specific and contributes to a significant diagnosis delay. Moreover, surrounding anatomical elements cause its pathology to be potentially serious and make surgical management challenging. Methods This retrospective study includes 7 cases presented with primary benign sphenoid sinus pathology managed between January 2019 and January 2022. Epidemiological features, clinical aspects, and treatment modalities are presented. Results Six female patients and one male patient were operated; their age ranges from 11 to 67 years old. Etiologies are divided into infection, tumors, and pseudo tumors. Sphenoid sinus approach was performed through the sphenoethmoid recess in 5 cases, through the septum in one patient and through the ethmoid in one patient. Conclusion Endoscopic procedures have significantly improved the management of the sphenoid sinus pathology. They offer good access and control of the sphenoid pathology but require a perfect mastery of radiologic and endoscopic anatomy and its variations.
