Maxillomandibular Rotational Advancement: Airway, Aesthetics, and Angle's Considerations.

Obstructive sleep apnea is a medical syndrome with multifactorial pathophysiology. Surgery can be the primary treatment option when anatomic factors are identified with narrowing at specific or general levels of pharyngeal airway. The surgeries are directed to the etiologic anatomic structure to achieve greatest effectiveness. Body weight, Mallampati scale, and tonsil grade are key evaluations to select effective surgical procedures. Surgical weight reduction, maxillomandibular advancement, and pharyngeal soft tissue surgeries are considered for the patient with obesity, maxillomandibular retrognathism, and tonsillar hypertrophy, respectively. Tailored surgical planning can meet the patients needs for airway, esthetics, and normal Angle's occlusion.

Isolated unilateral upper alveolar numbness in silent sinus syndrome.

We present a case of a 59-year-old man with left upper alveolar numbness of 2 years' duration in the absence of sinonasal symptoms. On physical examination, he demonstrated mild left facial asymmetry and diminished sensation of his left upper alveolus from the left second upper incisor to first canine. CT imaging revealed chronic sinusitis changes of the left maxillary sinus, with reduced volume and depressed anterior wall. The patient underwent functional endoscopic sinus surgery to re-establish maxillary sinus ventilation. He was noted to have some improvement of his upper alveolar paraesthesia postoperatively. Silent sinus syndrome is part of the spectrum of chronic maxillary atelectasis. In the presented case, chronic osteitic bony sclerosis, as opposed to osteopenic change of the maxillary sinus, was seen. We postulate that bony encasement of the anterior superior alveolar nerve resulted in chronic nerve compression and the patient's unusual symptom of upper alveolar paraesthesia.
