Thymoma with immunodeficiency with multiple recurrent oral herpetic infections.

Thymomas with immunodeficiency (formerly Good's syndrome) are a rare acquired disease of combined T- and B-cell immunodeficiency accompanying a thymoma. Recurrent opportunistic infections associated with disorders of both humoral and cell-mediated immunity frequently accompany this rare primary, adult-onset immunodeficiency. This is a report of a case of a thymoma with immunodeficiency in a 65-year-old male patient who developed recurrent oral herpetic infections.

Clinical comparison of submucosal injection of dexamethasone and triamcinolone acetonide on postoperative discomfort after third molar surgery.

Objective: The aim of the study was to compare the effect of submucosal injection of dexamethasone and triamcinolone acetonide on postoperative pain, swelling, and trismus occurring after impacted mandibular third molar surgery.

Method And Materials: A total of 78 patients (aged 18 to 35) with asymptomatic, unilateral, impacted mandibular third molar, and without any systemic disease were included in this study. Patients were divided into three groups randomly (control, dexamethasone, and triamcinolone acetonide).

Histological evaluation of the changes in temporomandibular joint capsule and retrodiscal ligaments following autologous blood injection.

Introduction: In recent years injection of autologous blood into the temporomandibular joint (TMJ) has been reintroduced as a treatment of chronic recurrent TMJ dislocation. The effects of this treatment on components of the TMJ is not fully understood. The purpose of this article is to evaluate the effects of autologous blood on TMJ capsule and the retrodiscal ligament.

Clinical study on the closure of extraction wounds of partially soft tissue-impacted mandibular third molars.

Objective: When a mandibular third molar is partially impacted in the soft tissue, it must be determined whether the extraction wound should be left partially open or completely closed. We hypothesize that a blood clot preserving a surgical wound with easily cleanable surfaces by primary closure and drain application would postoperatively minimize dry socket and/or alveolitis development.

Method And Materials: Twenty patients requiring bilateral extraction of partially soft tissue-impacted mandibular third molars in a vertical position were included in the study.

Ex vivo produced oral mucosa equivalent by using the direct explant cell culture technique.

Objective: The aim of this study is the histological and immunohistochemical evaluation of ex vivo produced oral mucosal equivalents using keratinocytes cultured by direct explant technique.

Material And Methods: Oral mucosa tissue samples were obtained from the keratinized gingival tissues of 14 healthy human subjects. Human oral mucosa keratinocytes from an oral mucosa biopsy specimen were dissociated by the explant technique.

Histomorphometric analysis of new bone obtained by osteogenic periosteal distraction in ovariectomized rabbits.

Objective: The aim of this study was to evaluate the effects of estrogen deficiency on newly formed bone obtained by osteogenic periosteal distraction histomorphometrically.

Study Design: Thirty-six female rabbits were divided into 2 groups. The experimental group underwent a bilateral ovariectomy and a sham operation was applied to the control group to equalize the stress of ovariectomy surgery.

Maxillary ameloblastoma mimicking an oroantral fistula.

Background: The aim of this current report is to present an unusual case of a maxillary ameloblastoma mimicking an oroantral fistula.

Case Report: A left subtotal maxillectomy via Weber-Ferguson-type incision was performed. The patient tolerated the procedure well, the postoperative course was uneventful, and the patient was discharged 3 days after surgery with a mild paraesthesia of the right infraorbital nerve distribution.

The evaluation of the effects of hyperbaric oxygen therapy on new bone formation obtained by distraction osteogenesis in terms of consolidation periods.

Objective: The aim of this study was to evaluate the effect of hyperbaric oxygen therapy on new bone formation obtained by distraction osteogenesis in long- or short-term consolidation periods.

Materials And Methods: Twenty-four rabbits were used. The animals were divided into two groups of 12 animals each, and vertical mandibular distraction osteogenesis was performed.

Oral metastasis of the mediastinal germ cell tumor (yolk sac).

A yolk sac tumor is a rare malignant tumor of germ cell origin. It most commonly arises from the testes and ovaries in young adults, but extragonadal sites of origin are reported in 10% to 15% of the cases. Yolk sac tumors are malignant, tend to recur locally, and may present with widespread metastases at the time of diagnosis.

Histomorphometric analysis of different latency periods effect on new bone obtained by periosteal distraction: an experimental study in the rabbit model.

Objectives: The aim of this study was to evaluate the effects of latency period on the bone formation after periosteal distraction. For this purpose, a rabbit model was developed and histologic and histomorphometric analyses were conducted.

Study Design: Periosteal distractors were custom designed and built from stainless steel.

Ploidy status of odontogenic tumors with epithelial components.

Objective: To evaluate the DNA ploidy status of different histologic types of odontogenic tumors (OTs) with epithelial components.

Study Design: Biopsy materials of cases that were diagnosed as ameloblastoma or OT with epithelial component were retrieved from archives. Routine hematoxylin-eosin sections were prepared from paraffin-embedded tumor materials.

Is endodontic treatment necessary during coronectomy procedure?

Purpose: Close proximity of the inferior alveolar nerve (IAN) to the third molar roots can result in nerve injuries during extraction of third molars. Consequently, it is necessary to determine the relationship of the nerve and roots to avoid damage to the IAN. Computed tomography scans are widely used to determine the correct relationship between the IAN and lower third molars.

Treatment of microstomia with commissuroplasties and semidynamic acrylic splints.

Microstomia is defined as an abnormal small oral orifice. Burns and injuries of perioral tissues, perioral surgeries, and genetic disorders can lead to perioral scar formations and restrict mouth opening. Treatment of microstomia requires surgical or conservative approaches.

Treatment of temporomandibular joint ankylosis with temporalis superficial fascia flap.

Temporomandibular joint (TMJ) ankylosis is characterized by the formation of bony or fibrous mass, which replaces the normal articulation and limitation of mouth opening. This study aims to determine the efficacy of arthroplasty and interpositional fascia flap in the treatment of unilateral and bilateral TMJ ankylosis in three young adult men. Our operative protocol for unilateral and bilateral TMJ ankylosis entailed resection of ankylotic mass, intraoral ipsilateral and bilateral arthroplasty, interpositional tissue transfer to the TMJ with temporalis superficial fascia flap, maxillomandibular fixation, and early mobilization and aggressive physiotherapy.

Osteoma of the mandibular condyle: report of a case with 5-year follow-up.

Osteomas of the mandibular condyle are rare. An unusual case of an osteoma occurring in the mandibular condyle of a 22-year-old man with mandibular deviation and malocclusion is reported; this represents the 14th documented case in the English language literature. The tumor was resected with condylectomy.

An analysis of maxillofacial fractures: a 5-year survey of 157 patients.

The purpose of this study was to review retrospectively the outcomes for 157 patients treated for maxillofacial fractures between 1994 and 1999 at one military hospital in Turkey. Significant data were collected according to age, gender, time of injury, type of facial injuries, cause of injury, treatment methods, and postinjury and postoperative complications. Fractures resulting from gunshot wounds were excluded in this study.
