This paper reports an unusual case of a transsphenoidal encephalocele and discusses our experience with a minimally invasive management. To the best of our knowledge, we present the first case of a combined endoscopic transnasal and transoral approach to a transsphenoidal encephalocele in an infant.
Metastatic cervical cancers to the oral cavity are uncommon. These metastases most commonly present as lesions of the jaw bones and the mandible. A 57-year-old female patient complained of mass lesion in her oral cavity after definitive treatment for squamous cell carcinoma of the cervix stage IIIB. On examination a swelling of 3cm in size was found on the left side of buccal vestibule adjacent to the lower canine tooth. Wide local excision was performed, and histopathology results showed a squamous cell carcinoma of moderate differentiation. She was continued with segmental mandibulectomy, supraomohyoid neck dissection and plate-screw reconstruction. Radiotherapy was given as an adjuvant therapy.
The objective of this study was to measure the topographic thickness of the lateral wall of the maxillary sinus in selected Asian populations. Measurements were made on the lateral walls of maxillary sinuses recorded using CBCT in a convenient sample of patients attending an Asian teaching hospital. The points of measurement were the intersections between the axes along the apices of the canine, first premolar, and second premolar and along the mesiobuccal and distobuccal apices of the first and second molars and horizontal planes 10 mm, 20 mm, 30 mm and 40 mm beneath the orbital floor. The CBCT images of 109 patients were reviewed. The mean age of the patients was 33.0 (SD 14.8) years. Almost three quarters (71.8%) of the patients were male. The mean bone thickness decreased beginning at the 10-mm level and continuing to 40 mm below the orbital floor. Few canine regions showed encroachment of the maxillary sinus. The thickness of the buccal wall gradually increased from the canine region (where sinus encroachment of the canine region was present) to the first molar region, after which it decreased to the thickness observed at the canine region. The buccal wall of the maxillary sinus became thicker anteroposteriorly, except in the region of the second molar, and thinner superoinferiorly. These changes will affect the approach used to osteotomize the lateral sinus wall for oral surgery and for the sinus lift procedure.
