Orbital fractures are frequently observed in maxillofacial trauma and can cause a wide range of functional impairments esthetic deformities. Many approaches have been used for the repair medial orbital wall fractures. It has necessary to use grafts or splints these approaches. We introduced new technique treat our patient with diplopia that resulted from fracture. In this method involves rotational repositioning fractured segment, there is no need graft another location synthetic material....
The infraorbital nerve is the largest cutaneous branch of maxillary divisions trigeminal nerve. It may produce a bony ridge on antral roof but usually goes through within bone as discrete canal. Rarely, it could be partially or completely dehiscent, lying submucosally in this case. We describe case longstanding facial pain because dehiscence canal associated with empyema. Endoscopic sinus surgery was successful relieving symptom.
Abstract Objectives In general, deviation of the L‐strut nasal septum is more challenging to correct than middle and has less favorable results. This study aimed develop a technique while preserving support effectively introduce L‐septoplasty its effects. Methods Patients with caudal high dorsal septal deviations who underwent were retrospectively analyzed. Preoperative three‐month postoperative comparative assessments included Nasal Obstruction Symptom Evaluation (NOSE) scale minimal...
The aim of this study was to determine how the sleep stage and body position influence effective pressure (Peff) in standard upward titration experimental downward titration. This applied successful manual continuous positive airway over 3 hours [including at least 15 min supine rapid eye movement (REM) sleep] followed by consecutive for 1 hour 22 patients with moderate-to-severe obstructive apnea. We analyzed baseline polysomnography variables compared pressures (Peff1upward Peff2downward)...
Rupture of the internal carotid artery (ICA) during endoscopic sinus surgery is a rare complication.However, it can potentially result in death within minutes.In event traumatic injury to ICA sphenoid exploration, very difficult control bleeding.We present case carotid-cavernous fistula after an accidentally-developed bleed sphenoidotomy.The patient was successfully treated with endovascular embolization techniques that included detachable microcoils.
We here report an extremely rare case of metastatic hepatocellular carcinoma to the nasal cavity only with MRI scan including diffusion-weighted imaging and a brief review previous literature reports.
Sphenoid sinus is placed deeper than the other paranasal sinuses. close proximity with critical structures like carotid artery, optic nerve. Because of this anatomical association, mucocele or sinusitis sphenoid has caused visual disturbance by neuritis. Optic neuritis generally defined as an inflammatory neuropathy nerve usually associated infectious, inflammatory, compressive, neoplastic, vascular processes. Degeneration demyelination occurs and leads to vision loss. We present two cases...
