Summary: | Surgical treatment of orbital wall fractures includes transnasal, transmaxillary sinus, and transorbital methods, and the transnasal method has been the main method performed in our department. We report a case of L-shaped fracture of the inferior orbital wall in which the fracture extended from medial to lateral along the anterior wall, and then from the anterior wall to the lateral part of the posterior wall. We used a combined transorbital and intranasal approach to treat the fracture. The transnasal approach consisted of endoscopic modified medial maxillectomy, and the transorbital approach was by means of a transconjunctival incision. Traditionally, the intranasal approach has been effective in treating fractures of the posterior infraorbital wall, but it has been difficult to repair anterior fractures, while the transorbital approach is effective for treating fractures of the anterior infraorbital wall, but it has been difficult to repair posterior fractures. The fracture in our patient extended from the anterior to the posterior infraorbital wall. We believe that the combined approach is useful in the treatment of extensive orbital wall fractures and that it is important to select the most appropriate procedure in each case.
眼窩壁骨折の外科的治療には,経鼻内法,経上顎洞法,経眼窩法があり,当科では経鼻内法が主に施行される術式であった。今回,眼窩下壁が前壁から外側にかけてL字型に広範囲に骨折している眼窩下壁の線状型骨折症例を経験した。術式は,経鼻内法に加え経眼窩法を併せたcombined approachによる整復術である。経鼻内法はEndoscopic Modified Medial Maxillectomyによるアプローチ方法であり,経眼窩法は経結膜切開によるアプローチ法である。従来から,経鼻内法は眼窩下壁後方の骨折には有効であるが前方の骨折に対しては整復困難とされ,経眼窩法は眼窩下壁前方の骨折には有効であるが後方の骨折に対しては整復困難とされている。本症例は,眼窩下壁前方から後方まで広範囲の骨折であり,combined approachによる整復術で術後に審美的な問題もなく,良好な術後経過であった。広範囲の眼窩壁骨折に対しては,combined approachによる整復術が有用であり,症例に応じた術式選択が重要であると考える。 |
