Background: To the best of our knowledge, there are no reports of penetrating orbitocranial injury (POCI) caused by a shoji frame.
Case Description: A 68-year-old man fell in his living room and was stuck headfirst by a shoji frame. At presentation, marked swelling was noted in the right upper eyelid, with the edge of the broken shoji frame exposed superficially. Computed tomography (CT) revealed a hypodense linear structure located in the upper lateral sector of the orbit, partially protruding into the middle cranial fossa. Contrast-enhanced CT revealed intact ophthalmic artery and superior ophthalmic vein. The patient was managed with frontotemporal craniotomy. The shoji frame was extracted by pushing out the extradurally located proximal edge from the cranial cavity and simultaneously pulling the distal edge from the stab wound in the upper eyelid. Postoperatively, the patient received intravenous antibiotic therapy for 18 days.
Conclusion: POCI can be caused by shoji frames as a result of an indoor accident. The broken shoji frame is evidently delineated on CT, which can result in prompt extraction.

Penetrating non-missile injuries to the head are an infrequent entity that commonly occurs as an accident.[
Shoji is a traditional Japanese style architecture that typically divides the indoor rooms and the hall that faces outdoors. Shoji is commonly wooden, takes the structure of lattice frames over which Japanese papers are stuck, and slides laterally to come and out of the room. Only one penetrating head injury caused by a shoji frame has been reported in literature.[
Herein, we present such a case wherein a shoji frame was successfully extracted through frontotemporal craniotomy.
A 68-year-old Japanese man fell in his living room and was stuck headfirst by a shoji frame. The patient visited a local ophthalmologist the day after the injury in the right upper eyelid, where he was suspected of penetrating orbital injury by a broken shoji frame. At presentation, the patient was well oriented. However, marked swelling and redness were noted on the right upper eyelid. In addition, the edge of the broken shoji frame was superficially exposed in the lateral part of the eyelid [
Non-contrast axial (a), coronal at the equator level of the bulb (b) and orbital apex (c), and sagittal (d) computed tomography, 3 mm in slice thickness, show a homogeneously hypodense, linear structure located in the upper lateral sector of the orbit, partially protruding into the middle fossa. Contrast-enhanced axial computed tomography revealed the ophthalmic artery (OA) and superior ophthalmic vein (SOV) to be intact (e). ACP : Anterior clinoid process, LRM : Lateral rectus muscle, SRM: Superior rectus muscle, Arrow: Fracture in the sphenoid bone, Arrowheads: Displaced inner table of the sphenoid bone, Asterisk: Broken shoji frame.
Intraoperative photos present step-by-step procedures of extraction. (a) Intradural view: site of the proximal edge of broken shoji frame is identified as a localized inner protrusion of the MF dura (arrowhead). (b) Extradural view: proximal edge of the shoji frame (arrowhead) is marked with pyoktanin blue. (c) Extradural view: proximal edge of the shoji frame (arrowhead) is being pushed out from the cranial cavity using a Penfield dissector (double asterisk). SV : Sylvian vein, MF: Middle fossa.
POCIs caused by wooden foreign bodies are rare. To the best of our knowledge, only ten cases including the present patient have been reported to date.[
All patients underwent a frontotemporal craniotomy or its modifications, followed by empirical antibiotic therapy. Treatment outcomes were satisfactory in seven of ten patients, while ophthalmoplegia persisted in two patients. The condition of the remaining patient was complicated by severe bacterial ophthalmitis as a result of residual foreign bodies in the orbit [
In the present case, a wooden foreign body was removed through a frontotemporal craniotomy. It was located in the upper lateral sector of the orbit, while partially protruded into the middle cranial fossa accompanied by fractures and possible dura tears. Therefore, we adopted craniotomy, instead of lateral orbitotomy, feasible for both intra-, and extradural procedures.
Wooden foreign bodies migrated in the orbital and cranial cavities have been documented to be missed on CT, indicating the diagnostic value of MRI in POCI cases.[
Broken shoji frames could be a strong weapon that can penetrate into the skull.[
POCI can be caused by a shoji frame as a result of an indoor accident. The broken shoji frame is evidently delineated on CT, which can result in prompt extraction after injury.
