OBJECTIVE: Through 3.0 T MRI study the ear and sinus lesions of patients with acute carbon monoxide poisoning. METHOD: From 2012 to 2015 collected the MRI images of the 45 patients with acute carbon monoxide poisoning, observe their changes of middle ear and mastoid and sinus imaging. RESULT: The middle ear injury of mastoid 41 cases (91.1%), 22 cases (48.9%) of maxillary sinus injury, ethmoid sinus injury in 20 cases (44.4%), sphenoid sinus 9 cases (20.0%), 5 cases (11.1%) of frontal sinus injury. Carbon monoxide poisoning patients according to clinical symptoms can be divided into light, medium and heavy 3 groups, observing the ear sinus damage degree for comparison between groups, found to have significant differences (P < 0.05). CONCLUSION The patients with acute carbon monoxide poisoning ear and sinus injury should cause the attention of the medical staff, MRI can reflect people's ears from the details and the damage degree of the sinuses.

Primary frontal sinus lymphoma is a very uncommon disease. In all the previously reported cases, the presenting symptoms have been due to the tumor mass effect. We present an unusual case report of an immunocompetent patient who presented with facial palsy, and then progressively developed other cranial nerve palsies over several months. He was later diagnosed with diffuse large B cell lymphoma originating from the frontal sinus. The patient underwent chemotherapy, but eventually had to receive autologous peripheral blood stem cell transplantation. He is currently disease-free. The clinical course, diagnostic workup, and therapeutic outcome are described.

Osteoma is a benign tumor arising from cancellous or compact bone. Frontal sinus is the most common site, followed by the ethmoidal sinus, maxillary sinus, sphenoidal sinus, maxilla and mandible. Very few cases involving the mandible have been described. A 26-year-old woman who had a limited range of mouth opening was reffered to our clinic. The limited opening had been gradually increasing in severity after first operation(reduction malarplasty and angle resection). Computed tomography images showed a radiopaque mass between left mandibular notch and zygomatic arch. After surgical removal of mass, diagnosis of mass was osteoma from clinical pathology. The postoperative course was uneventful, the patient could open the mouth about 40 mm, 5 months after the operation.

OBJECTIVES: Draf IIb approach provides wide, unilateral access to the frontal sinus. This approach can be extended without destruction of the contralateral frontal sinus drainage pathway, performed during Draf III (modified Lothrop) procedure. There is limited data in the literature regarding the use of modified Draf IIb procedures. METHODS: Patients treated with extended Draf IIb procedures in a single center were retrospectively assessed. RESULTS: Ten patients were identified, including 2 cases of osteoma, 1 inverted papilloma, 1 carcinoma, 5 mucoceles, and 1 chronic rhinosinusitis patient. Six patients had undergone prior surgery, including external procedures in 3 cases. Modifications of Draf IIb were classified as the following: removal of the anterosuperior nasal septum adjacent to the nasal beak, removal of the intersinus septum, and a combination of the above-mentioned methods (upper nasal septum and intersinus septum removal). There were 3 patients operated on with type 1 modification, one patient with type 2 modification, and 6 patients with type 3 modification. There were no perioperative complications. CONCLUSION: In selected cases, extended Draf IIb procedures are safe and effective in the treatment of frontal sinus disease.

Sinonasal intestinal-type adenocarcinoma is a rare neoplasm which can be diagnosed by pathologic report. Nasal obstruction, epistaxis, and rhinorrhea are common symptoms, but presenting with a benign-looking palpable mass is also possible. This is a report of our experience in diagnosing and treating a sinonasal intestinal-type low grade adenocarcinoma. A 63-year-old man initially presented with a rapidly growing palpable mass in the glabella region for 4 months. A malignancy of sinus origin was suspected on imaging studies. We performed further preoperative evaluations for cancer staging, and curative surgery was planned. Radical resection and immediate reconstruction with free anterolateral thigh flap were performed. The pathology findings confirmed a diagnosis of sinonasal intestinal-type adenocarcinoma.

Endoscopic sinus surgery is effective to nasal sinus mucocele with eye symptoms as main manifestation. It is very importment to raise the awareness of the disease and to prompt imaging examination. Three cases were reviewed. One mucocele was found in the frontal sinus ethmoid sinus,1 in the fronto-ethmoid sinus and 1 in the spheno-ethmoid sinus. All cases were preoperatively diagnosed by CT, MRI or intranasal endoscopy. Nasal sinus mucocele with eye symptoms as main manifestation should be early diagnosed. Endoscopic sinus surgery is a safe and effective method for the treatment of nasal sinus mucocele,and could be the primary choice for it. All cases were treated by nasal endoscopic sinus surgery. The majority of symptoms, such as exophthalmos, epiphora and diplopia, disappeared in all patients. However, vision recovery was observed only in some patients.

OBJECTIVE: Exploring the clinical features of aviatic nasal diseases to provide references for medical evaluation, prevention and control measures in aircrew. METHOD: To analysis and summary 605 cases with 503 pilots of nasal diseases in aircrew during 1966 to 2013. RESULT: (1) There were 605 cases of aviatic nasal diseases, including 550 cases of general diseases and 55 cases of specific diseases. The general nasal diseases included 140 cases of anatomical abnormalities in nasal cavity type, 290 cases of inflammation in nasal cavity, 73 cases of allergy type, 47 cases of cyst and tumor type, and the specific nasal diseases were 55 cases of sinus barotrauma (SB). (2) The, constituent ratio of SB, which was happened in frontal sinus and /or maxillary sinus, was 95.55%. (3) The constituent ratio of cyst and tumor type in nasal cavity was easier causing to SB than anatomical abnormalities, inflammation, allergy disease in nasal cavity (P < 0.05). (4) The grounded constituent ratio of secondary SB was higher than anatomical abnormalities, inflammation, allergy, cyst and tumor disease in nasal cavity (P < 0.05). (5) The ways of hypobaric chamber tests were different for the kinds of aircrew. The qualified adjustment function of sinuses for barometric pressure was an essential condition for aircrew to continue flying. (6) The key point for the treatment of aviatic nasal diseases was to remove pathological change in nasal cavity and sinus and restore sinus ostium patency. The key point for the medical evaluation was to restore normal sinus pressure balance function. CONCLUSION The key point of medical evaluation about aviatic nasal diseases is to assess the sinus pressure balance function in hypobaric chamber tests. Normative treatment and medical evaluation can effectively avoid flight accidents and improve the attendance rate for aircrew.
