ABSTRACT
OBJECTIVES:
Aim to evaluate the incidence and characteristics of nontraumatic dehiscence of the lamina papyracea (LP) via computed tomography (CT).METHODS:
The authors retrospectively studied 893 patients' history and paranasal sinus CT from February to September 2020. The datum of incidence and the characteristics of LP dehiscence were collected and analyzed.RESULTS:
The LP dehiscence was identified in 23 of 893 patients (2.58%). Lamina papyracea anatomical variations were categorized into Grade I, II, and III, which account 69.56%, 21.74%, and 8.70% of the entire dehiscence group. The average depth of LP ingression was 5.5 ± 0.7 mm. There was no statistical difference between bilateral incidence. The medial rectus muscle was involved in 3 lesions. In all CT reports, this anatomic variation was misdiagnosed as ethmoid sinusitis in 8 cases.CONCLUSIONS:
Preoperative cognition of the anatomic variation of LP via CT is conducive to decrease misdiagnosis and postoperative complications.
