The indications for surgical treatment for thyroid ophthalmopathy include decreased visual acuity caused by optic neuropathy, conjunctivitis and progressive facial deformity caused by exophthalmos. Orbital wall decompression by nasal endoscopy resulte in good cosmetic effects and visual recovery. alanced orbital decompression is considered to be a safe and effective surgery that can help avoid postoperative diplopia. We introduce three successful cases of orbital wall decompression for the treatment of thyroid ophthalmopathy.

고찰 2008년 European Group on Graves Orbitopathy(EUGO- GO) 의갑상샘눈병증의치료에대한표준지침에따르면, 경 증갑상샘눈병증은금연, 갑상샘기능유지, 인공눈물등의보조적인대증요법만권하며중등도- 중증갑상샘눈병증은면역억제요법이나수술요법이필요하다.

Coronal view of facial bone CT scan shows the effect of medial, inferomedial wall and lateral wall removal (D). 진시교정시력은우안 0.2, 좌안 1.0, 안압은우안 20 mm Hg, 좌안 20 mm Hg였으며, Hertel 안구돌출계검사에서우안 25 mm, 좌안 23 mm로양안의안구돌출을보였으며, 안구운동검사에서모든안위에서양안의안구운동제한이관찰되었다. 또한안구돌출로인한장기간의안구노출로양안의각막염소견이관찰되었다 (Fig. 5). 안면부컴퓨터단층촬영에서네개외직근의비후소견및양안의심한안구돌출이보였다 (Fig. 6 and ). 양안의갑상샘눈병증으로진단하고수술적치료를계획하였다. 수술은이전증례와마찬가지로내시경적비내접근법으로양안의안구내벽및하내벽감압술을, 외부접근법으로안와외벽감압술을시행하였다. 수술직후복시등수술과관련된합병증은발생하지않았으며, 술후 1개월째우안의시력 0.5로호전되었고안구돌출계는우안 19 mm, 좌안 18 mm로우안 6 mm, 좌안 5 mm의안구돌출교정효과가있었고복시및안구운동제한도호전되었다. 현재수술후 3개월째안구돌출등의재발없이경과관찰중이다 (Figs. 5, 6C and D). 고찰 2008년 European Group on Graves Orbitopathy(EUGO- GO) 의갑상샘눈병증의치료에대한표준지침에따르면, 경 증갑상샘눈병증은금연, 갑상샘기능유지, 인공눈물등의보조적인대증요법만권하며중등도- 중증갑상샘눈병증은면역억제요법이나수술요법이필요하다. 8) 특히스테로이드는항염증및면역억제작용뿐아니라증상을호전시켜우선적으로사용하도록권하고있으며방사선조사요법도시도되고있으나이러한치료에반응하지않거나복시, 시력감퇴등이발생하면수술을고려해야한다. 8) 갑상샘눈병증환자의수술적치료로 1911 년 Dollinger 에의하여외벽감압술이처음으로시행되었다. 1,9) 1950년에 Hirsch 는안와하벽의제거를시도하였고, Walsh 와 Ogura는안와하벽및내벽을제거하여약 4~6 mm의안구돌출교정효과를얻을수있다고보고하였다. 1,9) 보통안와하벽과내벽의감압술이많이사용되고있으며, 새로운복시의발생이가장흔한합병증으로알려져있다. 수술후복시의발생은수술방법및문헌에따라약 30% 에서많게는 60% 까지보고되며, 안구의내측또는하방편위때문에발생하는것으로생각된다 ) 이에 Graham 등 11) 은안와내벽과하벽및외벽을균형있게감압하는균형감압술 (balanced decompression) 을이용하면수술후복시의발생을 10% 정도로줄일수있다고하였으며, 본증례에서도안와외벽감압술을같이시행하였으며새로운복시등의합병증은발생하지않았다. 13) 수술시제거하는안와벽의제거개수에따라두벽감압술 (2 wall decom

6 Korean J Otorhinolaryngol-Head Neck Surg 2019;62(2): pression) 과, 세벽감압술 (3 wall decompression) 이있으며, 대개안구돌출정도가심한경우에세벽감압술을시행한다. European Group on Graves Orbitopathy 의연구에따르면같은정도의안구돌출에서교정효과는두벽감압술에서 4.3 mm, 세벽감압술에서 6.0 mm 정도로더큰것으로보고하였다. 12) 저자의보고에서앞의두증례에서는세벽감압술을하였지만모두 4 mm 정도안구돌출이호전되었는데, 이는안와하벽및외벽의감압정도가충분치않아서라고생각되며, 감압정도를증가시킨마지막증례에서는 6 mm 정도의안구돌출호전결과가있었다. 최근안와감압술시행시합병증을최소화하면서수술효과를최대로증대시키기위한노력이진행되고있다. 국내에서 Lee 등 14) 은수술전컴퓨터단층촬영사진으로외안근및안와지방의침범정도를평가하고수술중안구돌출정도를평가하여그에따라수술방법을달리하는단계적감압술 (graded decompression) 을소개하였다. 또다른보고에서는기존신경외과영역에서사용되던정위적수술항해장치를이용하면좀더안전하고효과적인안와감압술을시행할수있다고하였다. 15) 시력호전의정도를보면 Levy 등 6) 과 Tang 등 7) 에의한보고에서압박시신경병증환자에서내시경을이용한안와감압술후모든예에서확연한시력의개선을보였다고하였으며, 본보고의첫증례에서도 1.0으로만족할만한시력회복을보였다. 갑상샘눈병증환자에서내시경을이용한비내접근법의장점으로흉터가남지않는다는점에서미용적인효과가있으며, 출혈및부종의감소등으로수술후기능적인회복또한기존수술법에비해유리할것으로보이고, 내시경을이용하면시신경및안와구조물이밀집해있는뒤쪽까지쉽게접근하여감압할수있으므로첫증례와같이갑상샘눈병증환자에서압박시신경병증을동반하는경우더욱효과적이라고보고된다. 6,7) 내시경수술시문제점으로지적되던수술시야의협소함및기구사용의어려움등은장비의발달에힘입어개선되고있으며, 내시경을활용하는수술분야가늘어나면서술자의숙련도및기구의편리성도점차증대되고있다. 아직이비인후과에서는내시경을이용한비강내접근법이, 안과에서는결막경유법등의외부접근법에익숙하다. 하지만안와내벽및하벽뿐만아니라복시등의합병증을줄여주고수술결과도극대화할수있는외벽감압술도같이시행하면더좋은결과를얻을수있을것이라고생각되며, 향후본증례와같이갑상샘눈병증환자에서뿐만아니라안와골 절, 안와종양등의분야에서내시경을이용한비내접근법은 더욱유용하게활용될수있을것으로보인다. 저자들은세명 의갑상샘눈병증환자에서비내시경을이용한안와내벽및 내하벽안와감압술과, 외안각접근법을이용한외벽감압술을 시행하였으며, 특별한합병증없이안구돌출및시력이호전 되었기에문헌고찰과함께보고하는바이다.
