The etiopathogenesis of coronoid process enlargement has not been clearly clarified and no mechanism has been found to explain this overgrowth yet. Coronoid process hyperplasia cause the limitation of the mouth opening by the impingement of the coronoid process to the zygomatic arch. Treatment method may comprise surgical removal of the process or osteotomy alone. In the present case, a 22-year-old male patient with bilateral coronoid hyperplasia without any metabolic syndrome related disorder is reported. Coronoidotomies were performed bilaterally under general anesthesia. Temporomandibular joint (TMJ) problems like clicking, popping, and pain were encountered after physiotherapy. Arthrocentesis was performed for both joints. TMJ problems subsided after the arthrocentesis procedure. In the first year of the follow-up, no relapse was reported. TMJ problems might arise as a consequence of fibrous ankylosis of the articular joint due to the restriction which was present for several years. Arthrocentesis could be beneficial after the coronoidotomy or coronoidectomy procedure.
Koronoid prosesin uzamasının etyopatogenezisi henüz açıklığa kavuşmamıştır ve henüz bu aşırı büyümeyi açıklayan hiçbir mekanizma bulunmamıştır. Koronoid proses hiperplazisi, koronoid prosesin zigomatik arka çarpmasıyla ağız açıklığının sınırlandırılmasına neden olur. Tedavi yöntemi, prosesin cerrahi olarak çıkarılmasını veya tek başına osteotomiyi içerebilir. Mevcut olguda, metabolik sendrom ile ilişkili herhangi bir bozukluğu olmayan bilateral koronoid hiperplazisi olan 22 yaşındaki erkek hasta bildirilmektedir. Koronoidotomiler genel anestezi altında bilateral olarak uygulandı. Fizyoterapiden sonra temporomandibuler eklem (TME)’de klik, krepitasyon ve ağrı gibi problemlerle karşılaşıldı. Her iki eklem için artrosentez uygulandı. TME sorunları artrosentez prosedürünün ardından düzeldi. Takip edilen ilk yılda relaps bildirilmedi. TME problemleri, birkaç yıldır var olan ağız açmada kısıtlılık nedeni ile eklem fibröz ankilozunun bir sonucu olarak ortaya çıkabilir. Artrosentez, koronoidotomi veya koronoidektomi prosedürünün ardından yararlı olabilir.
