Analysis Of Paranasal Sinus Fibrous Dysplasia In 36 Cases

Objective:To explore the clinical features,surgical approaches,and treatment outcomes of patients with paranasal sinus fibrous dysplasia.Methods:A retrospective review of 36 patients with paranasal sinus fibrous dysplasia treated between October 2009 and October 2016 was performed.All patients underwent surgery based on the results of preoperative imaging.Nasal endoscopic resection was performed in 16 cases,a Caldwell-Luc procedure in 4,lateral rhinotomy in 7combined nasal endoscopic resection and Caldwell-Luc procedure in 4,coronal incision craniotomy in 3,coronal incision craniotomy combined with Caldwell-Luc procedure in 2,and optic canal decompression in 3.Results:Of 36 cases followed for 6-60 months,2 developed a recurrence and the remaining 34 recovered without difficulty.Cerebrospinal fluid rhinorrhea occurred in 2 cases,and 1 case had an intracranial hematoma.Of the 36 cases,28 underwent radical bone resection and 8 underwent conservative excision to improve function and appearance.Conclusion:Paranasal sinus fibrous dysplasia presents with complex clinical manifestations.Surgical resection of affected bone is the main treatment,while retaining function and appearance as much as possible,based on preoperative imaging and patient preferences.The prognosis is good,with low rates of recurrence or malignant transformation...
