Hypertelorism Secondary to Mucocele in the Paranasal Sinuses

Ocular hypertelorism was introduced by Greig as an increased interpupillary distance. The paranasal sinus mucoceles are acquired lesions for various reasons; however, their behavior is progressive, capable of eroding the bone and extending to the orbital and intracranial regions. The objective is to present a clinical case of orbital hypertelorism secondary to mucocele in the paranasal sinuses. This is a 72-year-old male patient who came presenting an increase in volume in the right nasoorbitoethmoidal region. The isodense lesion occupying the maxillary and right ethmoidal sinuses was confirmed by an intimate relationship with the ipsilateral frontal and sphenoidal sinus, with osteolytic involvement of the orbit and nasal region. After incisional biopsy with mucocele results, a wide resection plus facial reconstruction was performed with autologous grafts and osteosynthesis material. Currently, the patient has 1 year of evolution, without significant functional commitment. It is important to consider giant mucoceles as part of the differential diagnoses in patients with deformities in the middle and upper third of the face.
