ABSTRACT
Angle's class III malocclusions are characterized by the anterior positioning of the mandible in relation to the maxilla. The discrepancy can be caused by an anterior deficiency of the maxilla, excessive mandibular prognathism, or a combination of both. Acromegaly is a dysfunction caused by the excessive production of growth hormone (GH), which leads to systemic changes and orofacial manifestations. In acromegaly caused by a pituitary adenoma, which secretes an excessive amount of GH, disproportionate mandibular growth may occur, leading to skeletal class III malocclusion in adulthood. Excessive growth stops when the tumor is removed, but the skeletal deformity persists, requiring orthognathic surgery to reposition the mandible. This article reports the case of a 31-year-old man referred to the maxillofacial surgery consultation due to severe Angle's class III malocclusion, with prognathism, mandibular asymmetry, and maxillary retrusion. He had a history of disproportionate soft tissue growth (hands and feet) up to 18 years old, less evident after that age. Considering the possibility of acromegaly due to a pituitary adenoma, imaging studies (CT scan and magnetic resonance imaging (MRI)) and directed analytical studies were requested. When the diagnosis was confirmed, the patient was referred to endocrinology and neurosurgery consultations. After undergoing endoscopic resection of the pituitary adenoma, the patient underwent surgery-first orthognathic surgery to correct the dental malocclusion.
ABSTRACT
This case report aims to present the successful reconstruction of a nasal defect in a 56-year-old male patient who suffered a partial nasal amputation due to a domestic accident involving a grinding wheel. The reconstruction was carried out using a paramedian frontal flap in a two-stage surgical process. Initially, the flap was designed and customized to match the dimensions of the defect, with a pedicle width of approximately 1.5 cm vertically. The flap was elevated in a distal-to-proximal manner, starting with subcutaneous dissection and progressing to periosteal dissection proximally. Weekly dressing changes were made using fatty gauze and fusidic acid ointment. Four weeks postoperatively, the flap pedicle was divided, and the brow was repositioned. At the six-month follow-up, the patient showed satisfactory clinical outcomes with no functional complaints and was very pleased with the aesthetic result. Paramedian frontal flap reconstruction is a dependable technique for addressing nasal defects following traumatic amputation, providing favorable functional and aesthetic results. This case highlights the importance of careful surgical planning and technique in achieving successful facial reconstruction.
ABSTRACT
The presence of sinonasal ectopic teeth is a rare entity that is usually asymptomatic. In some cases, the presence of foreign bodies in the maxillary sinus, such as ectopic teeth, can lead to chronic maxillary sinusitis. We report a case of chronic sinusitis because of an ectopic tooth in the roof of the left maxillary sinus in a 50-year-old female who presented with complaints of facial pain in the left maxillary region and purulent nasal discharge. The treatment of ectopic teeth usually consists of the removal of the previous, taking into account its location and possible risks. In this case, the close proximity to the orbit could have led to a greater risk of complications involving the infraorbital bundle. CT scan evaluation is frequently required to identify the exact location and is useful for treatment planning. The traditional surgical approaches to maxillary sinus pathology are transoral Caldwell-Luc approaches or transnasal endoscopic surgery. The method used in this case was the Caldwell-Luc approach. Although more invasive, it allows visualization into the maxillary sinus and superior access for instrumentation of the posterolateral region while permitting manipulation and removal of larger objects. Despite maxillary sinus ectopic teeth being uncommon, it is important for clinicians to become aware and to consider this entity to provide early adequate treatment.
