The excision of a giant mastoid process osteoma can be challenging. In such situations, the three-dimensional exoscope intra-operative optic may be a promising tool.

This paper provides a technical description of a giant mastoid osteoma excised under three-dimensional exoscope magnification. A fragmented excision by intralesional curettage was adopted to prevent peri-tumoural damage. This technique had been previously described for the excision of large osteomas of the sinus.

The three-dimensional exoscope magnification tool had excellent applicability during surgery of a rare mastoid osteoma. In complex anatomical areas, the cavitation and fragmented excision of the tumour may prevent complications and is therefore recommended.

External approaches have been traditionally used for the complete excision of large retropharyngeal space lesions.

This paper describes a case of a large schwannoma of the retropharyngeal space excised transorally with the use of a robotic system. This lesion measured 2.7 × 1.2 cm in axial dimensions and over 5.8 cm in craniocaudal length. The lesion was delivered en bloc with an intact capsule. No peri- or post-operative complications were encountered. The procedure allowed quick resumption of an oral diet and a return to normal activity for the patient.

This is, to our knowledge, the first report of this technique used in the excision of a large retropharyngeal space mass.

This study aimed to describe the results of a retrospective analysis of a specific cohort of patients with benign lip lesions encountered in the last 15 years in the School of Medicine at Karadeniz Technical University.

A total of 312 patients were managed for lip lesions during the period 2000–2014. Data from 160 samples of benign lip biopsies were retrieved from the pathology laboratory records.

The study group included 20 different histopathological types of lesions, with mucocele being the most frequent lesion (43.13 per cent). The other frequent lesions were chronic inflammatory infiltrate (11.25 per cent), intradermal naevus (5.63 per cent), pyogenic granuloma (5.63 per cent), fibroma (5 per cent) and papilloma (5 per cent). Mucocele was significantly more common in younger patients (p < 0.001).

Knowledge of the epidemiology and distribution of oral mucosal lesions is essential to promote early diagnosis and treatment. Further epidemiological studies exploring the causal relationships and risk factors for lip lesions are necessary for a better understanding of lip diseases.
