The impact of zygomatic buttress bone graft on nasal floor augmentation in unilateral alveolar cleft patients with late referral: A case series.

Purpose: This preliminary study aimed to assess the efficacy of zygomatic buttress bone grafting for nasal floor augmentation in patients with a unilateral alveolar cleft who were referred after the optimal timetable for this surgery had elapsed.

Case Series: Five patients, aged 12-18 years, with unilateral alveolar clefts were treated at Qaem Hospital, Mashhad, Iran. Initially, a mucous layer was established on the side of the cleft nose, followed by forming a bony bridge between the defect's sides through a bone graft derived from the zygomatic buttress and xenograft bone powder.

Temporoparietal Flap for Facial Reconstruction: Donor Site Morbidity.

Background: Temporoparietal flap (TPF) is recommended when thin delicate tissue for medium sized defect is needed. The most used form of this flap is for auricle reconstruction. In this article usage of this flap for facial reconstruction other than auricle is discussed, emphasing on donor site morbidity.

Cross Lip Vermilion Flap and Traumatic Upper Lip Avulsion: Reducing Donor Site Morbidity.

Using a cross lip vermilion flap for upper red lip reconstruction in cases other than whistle deformity in patients with cleft lip can lead to donor site morbidity. If the practitioner performs primary closure of the mucosa in lower vermilion after flap harvesting, the width and height of lower lip are reduced, which results in an increased lower incisor tooth show. Using free fat grafting is an effective method for reducing donor site morbidity in the lower lip following cross lip vermilion flap harvest.

Pharmacological and Non-Pharmacological Methods of Postoperative Pain Control Following Oral and Maxillofacial Surgery: A Systematic Review.

Background: We aimed to investigate the pharmacological and non-pharmacological interventions used for mitigating pain.

Methods: We integrated randomized controlled trials (RCTs) chosen from PubMed, Google scholar, and Scopus and aimed at assessing the effectiveness of one or multiple variants of Non-steroidal anti-inflammatory drugs (NSAIDs), as well as Narcotic analgesics, compared to corticosteroids, curcumin, hyaluronic acid, and antibiotics. In addition, trials utilizing NSAIDs, including Rofecoxib, which have been withdrawn from market circulation, were deemed ineligible for inclusion.

Synovial sarcoma of the maxilla: A challenging diagnostic case report and literature review.

Synovial sarcoma, a malignant mesenchymal tumor, is primarily associated with the extremities. Nevertheless, its appearance within the head and neck region, particularly in the maxillary area, is remarkably rare. This rarity underscores the significance of each case in unraveling the complexities of its behavior and management strategies.

Delayed Management of Parotid Sialocele: Role for Two-week Intraoral Drainage.

Iatrogenic injury or trauma to the salivary gland duct is one of the most common causes of parotid sialoceles, which are usually superficial, soft, and filled with saliva. The enrolled 7 patients with parotid sialocele were divided into two groups: trauma group (4 cases) and iatrogenic group (3 cases). No evidence of recurrence or cranial nerve injuries were observed.

Bimaxillary Orthognathic Surgery Does Not Induce Obstructive Sleep Apnea in Skeletal Class III Patients.

Purpose: Since the relationship between mandibular setback surgery and obstructive sleep apnea (OSA) occurrence still remains controversial, the aim of this study was to assess the impact of bimaxillary orthognathic surgery on the probability of OSA development, using a home sleep test (HST) device.

Methods: The authors implemented a double-blinded prospective cohort study. All healthy patients with skeletal class III deformity were included in this study.

Facial Artery Musculomucosal Flap in Alveolar Cleft Surgery.

Introduction: Large anterior palatal fistula and special alveolar clefts, such as edentulous atrophic premaxilla and absent premaxilla (premaxillectomy or agenesis), as well as wide unilateral alveolar cleft, are complicated cases in alveolar cleft bone grafting surgery. A superiorly-based buccinator myomucosal flap is suitable in this regard.

Materials And Methods: The cleft patients whose large anterior palatal fistula and superiorly based buccinator myomucosal flap had been used for palatal or alveolar reconstruction were recruited in the study.

Buccal Fat Pad Graft in Maxillofacial Surgery.

Despite the widespread use of pedicled buccal fat pad (BFP) flap in maxillofacial reconstruction, free nonvascular transfer of this fat is not widely used. Dermal fat transfer to the maxillofacial region is a known procedure with good results; however, it needs a skin incision in the donor site. Resorption of this graft is the other problem.

A case series of uncommon causes of maxillary osteomyelitis: Understanding the pathology and recognizing the risks.

Maxillary osteomyelitis is a rare event. With emergence of bisphosphonates, the incidence of jaw osteomyelitis has increased. We report five uncommon cases, with a comprehensive review of etiology and pathology.

Pheochromocytoma Metastasing to the Jaw: Review of the Literature and New Case.

Pleochromocytoma is a benign neuroectodermal tumor of the adrenal medulla. Ten to thirty percent of these tumors become metastatic. The bone is the most frequent site for metastasis but jaw involvement is reported rarely.

Donor Site Morbidity in Submental Flap: Emphasizing on Facial Hairs Direction.

Introduction: Donor site morbidity is an important factor for selecting a flap for reconstruction. Submental flap using submentum skin for reconstruction has low donor site morbidity. Up to now, donor site morbidity of submental flap in Caucasians has not been evaluated.
