Temporomandibular joint pain dysfunction syndrome (TMJPDS) is the most common temporomandibular disorder. This condition presents with symptoms of pain, restricted jaw movement and joint noise. Other symptoms include otalgia, headache, neck pain and trismus.
To determine the pattern of Temporomandibular joint pain dysfunction syndrome patients managed at the Lagos University Teaching Hospital, Lagos, Nigeria.
A descriptive study of patients with signs and symptoms of Temporomandibular joint pain dysfunction syndrome attending the Oral Medicine Clinic of Lagos University Teaching Hospital.
Twenty-one patients with Temporomandibular joint pain dysfunction syndrome were enrolled into the study, out of which 10(48%) were females and 11(52%) were males. The age range was 23-81years with a mean of 45.2 ± 18.9 years. Majority of the patients 20(95.2%) complained of pain around the joint, in the pre-auricular region, in the muscles of mastication and the ear. While 7(35%) complained of clicking sounds, 10(47.6%) complained of pain on mouth opening and during mastication only. In all 5(23.8%) had impaired movement of the jaws, mouth opening was normal in 18(85.7%) but reduced in 3(14.3%) patients. Over half of patients 12(57%) experienced clicking sounds, there was tenderness around the temporomandibular joint in 16(76.2%) cases, pain in the ear of 7(33.3%) patients and 13(61.9%) people presented with tenderness of the muscles of mastication. Conservative management of all the cases resulted in resolution of the symptoms.
Temporomandibular joint pain dysfunction syndrome has diverse clinical presentation and though distressing, it responds to prompt and effective conservative management.

确定在尼日利亚拉各斯大学教学医院接受治疗的颞下颌关节疼痛功能紊乱综合征患者的情况。
对拉各斯大学教学医院口腔内科门诊中出现颞下颌关节疼痛功能紊乱综合征体征和症状的患者进行描述性研究。
21例颞下颌关节疼痛功能紊乱综合征患者纳入本研究，其中女性10例（48%），男性11例（52%）。年龄范围为23至81岁，平均年龄为45.2±18.9岁。大多数患者20例（95.2%）主诉关节周围、耳前区、咀嚼肌和耳部疼痛。7例（35%）主诉有弹响，10例（47.6%）仅主诉张口和咀嚼时疼痛。共有5例（23.8%）下颌运动受限，18例（85.7%）张口正常，3例（14.3%）患者张口度减小。超过半数患者12例（57%）有弹响，16例（76.2%）颞下颌关节周围有压痛，7例（33.3%）患者耳部疼痛，13例（61.9%）咀嚼肌有压痛。所有病例经保守治疗后症状均缓解。
颞下颌关节疼痛功能紊乱综合征临床表现多样，尽管令人痛苦，但对及时有效的保守治疗有反应。
