“…The proposed causes include temporal muscle hyperactivity, which could lead to increased vascular supply and reactive elongation of the coronoid process (2). Other proposed causes are previous trauma (as in our patient), chronic disc displacement, endocrine disruptions, and genetic abnormalities (3)(4)(5)(6)(7). Patients with Jacob's disease complain of progressive limitation of mouth opening.…”

“…Although predominantly unilateral, bilateral cases have been reported (1). The pathogenesis of this disease remains uncertain, and proposed causes include temporal muscle hyperactivity (2), previous injury, chronic disc displacement of the ipsilateral temporomandibular joint (TMJ), endocrine stimuli, and genetic alterations (3)(4)(5)(6)(7). The condition first manifests with progressive limitation of mouth opening and deviation from the midline towards the affected side (1), accompanied in most cases by midface asymmetry resulting from a deformed malar bone.…”

The formation of a new joint between a pathologically elongated coronoid process and the body of the malar homolateral bone is known as Jacob's disease. Coronoid process hyperplasia was first described in 1853 by Von Langenbeck, and it was not until 1899 when Oscar Jacob described the disease that it was named after him. Jacobs's disease is an uncommon entity with only a few documented cases in the literature. The condition first manifests with progressive limitation of mouth opening and facial asymmetry. Pain is uncommon and it mainly affects young patients. Different factors have been postulated as possible causes, including temporal muscle hyperactivity, previous trauma, chronic disc displacement of the ipsilateral temporomandibular joint, endocrine stimuli, and genetic alterations. Definitive diagnosis is by histopathology and it is necessary to confirm bone hyperplasia, the presence of cartilage and synovial capsule forming the new joint between the malar bone and the coronoid process. We report a 52-year-old woman patient with a history of childhood trauma in the right preauricular region. She came to our department with a 2-year history of progressive limitation of mouth opening. Computed tomography (CT) revealed a right coronoid process elongation, in contact with the homolateral malar bone, causing it to deform. Surgery with general anesthesia was performed using an intraoral vestibular approach. Histopathology confirmed the diagnoses of Jacob's disease.

Trismus is defined as the tonic contraction of the muscles of mastication that can dramatically affect quality of life in a variety of ways. Trismus occurs in head and neck cancer patients as a result of tumours in or around the region of masticatory muscles or after radiotherapy treatment. It has been known that it occurs after radiotherapy treatment in the ratio of %5-38. Treatment modalities for limited mouth opening include coronoidectomy,coronoidotomy and aggressive physical therapy alone or combined.In this case report, intraoral coronoidotomy treatment of a patient with limited mouth opening due to radiotherapy treatment for nasopharynx cancer is presented.Key Words: Radiotherapy, Coronoidotomy, Trismus. ÖZETTrismus; çiğneme kaslar›n›n tonik kontraksiyonu olarak tan›mlanan yaşam kalitesini negatif yönde etkileyen bir semptomdur.Baş ve boyun kanserli hastalarda tümörün kas içine yay›lmas›yla meydana geldiği gibi tedavi amaçl› uygulanan radyoterapiye bağl› olarak da meydana gelebilmektedir. Yap›lan çal›şmalarda radyoterapi sonras› trismus oluşumu oran› % 5-38 olarak bildirilmektedir . Bu vakalarda trismusa bağl› s›n›rl› ağ›z aç›kl›ğ›na yönelik tedavi seçenekleri koronoidektomi, koronoidotomi ve yoğun fizyoterapi seçeneklerinden biri ya da kombine kullan›mlar›n› içermektedir. Bu vaka raporunda nazofarinks karsinomu tedavisi amac›yla radyoterapi görmüş bayan hastada trismusa bağl› k›s›tl› ağ›z aç›kl›ğ›n›n intraoral koronoidotomi ile tedavisi bildirilmektedir.Anahtar Sözcükler: Radyoterapi, Koronoidotomi, Trismus. GİRİŞTrismus hastan›n çene ekleminin ankiloz olmadan ağz›n› açamamas›d›r.Trismus çene ekleminin iltihab›,bruksizm,anestezinin yanl›ş bölgeye enjeksiyonu,travma,tümoral olaylar sonras›nda s›kl›kla görülmektedir. Ağz›n yeterince aç›lamamas›, bozulmuş artikülasyon, oral kavite rezonans›n› sağlayan hacmin azalmas› ve böylece vokal kalitenin bozulmas› iletişimi zorlaşt›rmakta, ciddi trismus halinde oral hijyen, çiğneme ve yutma fonksiyonlar› olumsuz yönde etkilenmekte ve aspirasyon riski artmaktad›r.Çene hareketlerindeki k›s›tlamalar; kas, eklem hasar›, bağ dokusunun h›zl› art›m› veya bunlar›n bileşiminden kaynaklan›r. Trismusda mastikatör kaslar›n her birinin (temporal, maseter, medial ve lateral pterigoidler) hasar› ile ağ›z aç›lmas›nda k›s›tlamalara yol açabilir. Kas hasar›yla ağr› refleksi stimüle olur ve bu durum kontraksiyona yol açarak hareketi k›s›tlar (2, 3).

El tratamiento es la coronoidectomía para que los movimientos mandibulares ya no estén restringidos. A pesar del tratamiento quirúrgico es muy importante realizar fisioterapia postoperatoria. Aquí les proponemos el uso de aparatología ortopédica funcional para mejorar la abertura oral postoperatoriamente. © 2013 SECOM. Publicado por Elsevier España, S.L.U.

Hyperplasia of the mandibular coronoid process: A new post-surgical treatment Keywords:Coronoid process hyperplasia Limited mouth opening Maxillary functional orthopedics a b s t r a c t Mandibular coronoid process hyperplasia is a rare condition, characterized by an enlarged coronoid process, leading to a restriction in mandibular opening due to contact of the coronoid process with the posterior surface of the malar bone.The treatment involves coronoidectomy, gaining free movement of the mandible, and afterwards, active physiotherapy. A novel adjunctive protocol with functional orthopedic device is proposed.

Acosta Behrends).Esta entidad fue descrita por primera vez por von Langenbeck en 1853 2 , y publicada ampliamente en 1963 por Rowe 3 , quien la describe como una anormalidad de los procesos coronoideos, dividiéndolos en 2 tipos, causados por el desarrollo o por cambios neoplásicos. Los neoplásicos se caracterizan por ser unilaterales mientras que los del desarrollo son bilaterales, http://dx.
