title: [Clinical analysis of primary nasal sinus osteoma].
abstract: OBJECTIVE
  To summarize and analyze the clinical features, diagnosis, surgical approaches and treatment outcomes of patients with primary nasal sinus osteoma.
  
  
  METHODS
  A retrospective review of 48 cases with primary nasal sinus osteoma treated from January 2007 to December 2013 was performed. All patients underwent preoperative CT scan and postoperative histopathologic examination. The surgical approaches included lateral rhinotomy in 14 cases, nasal endoscopic resection in 12 cases, coronal surgical incision craniotomy in 13 cases, combined craniofacial approach in 4 cases, and Caldwell-Luc approach in 5 cases.
  
  
  RESULTS
  The postoperative pathological diagnosis consisted of 3 variants, including 20 for compact type and 15 for cancellous type, and 13 for mixed type. Six cases were lost to follow-up and 42 cases were followed up for 6-60 months, 5 cases recurred. The post-operative complications included sinus mucous cyst in 4 cases, cerebrospinal fluid leak in 3 cases.
  
  
  CONCLUSIONS
  Nasal sinus osteoma are common. CT or MRI is helpful to evaluate the osteoma size, location and possible sources, and to make operation scheme. Surgery is the first choice for sinus osteoma. Lateral rhinotomy and nasal endoscopic resection can be applied to most sinus osteoma. The prognosis of sinus osteoma is good, with fewer recurrence.
