Subnasal modified Le Fort I osteotomy: indications and results.

PURPOSE: To study the possible morphologic changes in the nose after subnasal modified Le Fort I maxillary osteotomy to correct class III dentofacial deformities in patients with considered normal nasal morphology. MATERIAL AND METHODS: Fifteen patients (7 males, 8 females) requiring maxillary advancement to treat class III dentofacial deformities were studied prospectively between January 2004 and January 2011. All the patients had an adequate projection of the nasal tip preoperatively preventing a conventional Le Fort I osteotomy. Patients received preoperatively (T1), 6 months after surgery (T2), and 12 months after the initial surgical procedure (T3) lateral cephalograms, CT-3D studies and clinical nose analysis to measure different morphologic variables including: the alar/nose base width, nasal tip protrusion and nasal bridge length using a digital sliding caliper directly on the soft-tissue surface of the face. RESULTS: Mean age was 26.2 years, range 20-36 years. A significant advancement of the maxilla was noted postoperatively (mean 7.5 mm). After surgery the different anthropometric variables of the nasal region analysed had not suffered any significant variation. No significant differences were found when comparing T2 with T3 measures. No significant complications were found. CONCLUSION: The results indicated that maxillary advancement using a subnasal modified Le Fort I osteotomy can prevent undesirable soft tissue changes of the nose when anterior repositioning of the maxilla is indicated in patients with preoperatively normal nasal morphology.

Treatment of bilateral hyperplasia of the coronoid process of the mandible. Presentation of a case and review of the literature.

Bilateral hyperplasia of the coronoid process is infrequent. It consists of an elongation of the coronoid process of the mandible and is, accordingly, a mechanical problem, limiting mouth opening. This article looks at the case of a 28 year-old male with significant limitation on opening his mouth, secondary to bilateral hyperplasia of the coronoid process. We reviewed the literature and analysed the diagnostic and therapeutic procedures used, paying special attention to the surgical approaches to the coronoid process and emphasising the importance of early post-operative rehabilitation, describing our experience with the TheraBite (Atos Medical AB, PO Box 183, 242 22 Hörby, Sweden). The satisfactory result of the procedure is marked by the stable recovery of the mouth opening, achieved by a good combination of surgical and physiotherapeutic techniques.

Surgical treatment of benign parapharyngeal space tumours. Presentation of two clinical cases and revision of the literature.

Parapharyngeal space (PPS) tumours, most of them benign, account for some 0.5% of tumours of the head and neck. The importance of these tumours lies mainly in two aspects: on the one hand, the difficulty of early diagnosis, due to the lack of symptoms in the initial stages and, on the other, the extreme complications of performing surgery in the parapharyngeal region. This article discusses two clinical cases of parapharyngeal space tumours: a 45 year old man and a 60 year old woman. We revise the scientific literature and analyse the diagnostic and therapeutic procedures used, placing special emphasis on describing the different surgical approaches to the parapharyngeal space: transcervical, transcervical-transparotid, transpalatal or transoral, transmandibular and orbitozygomatic, all of which, used alone or combined with others, allow for complete resection of these tumours with minimum morbidity.
