Watching Food Videos Leads to Postparotidectomy Salivary Fistula.

Salivary fistula is a common postparotidectomy complication, and eating sour or spicy food ranks among the leading causes. Here we report a rare postparotidectomy salivary fistula case, a 31-year-old female patient who affirmed that she did not eat any irritating foods but admitted that she had been watching food videos for up to 4 hours every day since she left hospital. This case offers a cautionary tale about postparotidectomy precautions.

Myofascial iliac crest flap for reconstruction of combined oral mucosa-mandibular defects: A single-centre experience.

BACKGROUND: Deep circumflex iliac artery (DCIA) myofascial iliac crest flap has been used for combined oral mucosa-mandibular defects reconstruction. The bone component of this composite flap can reconstruct the mandible with superior contour match, and the muscle fascia which used for repairing the oral mucosa defect will transform into an oral mucosa-like appearance. To explore its scope of clinical application and how the fascia transformed into oral mucosa will give surgeons flexibility to reconstruct the combined oral mucosa-mandibular defects. METHODS: A retrospective review of 18 patients who received combined oral mucosa-mandibular defects reconstruction with DCIA myofascial iliac crest flaps from Dec 2016 to Dec 2020 was performed. The characteristics of the mandibular defects and the flaps were recorded. The postoperative dynamic changes of one graft's fascia were observed from serial photographs. RESULTS: All myofascial iliac crest flaps survived successfully. The bone grafts were from 4.0 to 9.5 cm (mean 7.6 ± 1.5 cm) in length and from 2.0 to 3.5 cm (mean 2.7 ± 0.4 cm) in height. The sizes of fascia were from 13.5 to 48.0 cm2 (mean 27.2 ± 9.4 cm2). The grafted fascia firstly changed into a yellow pseudomembrane-like appearance, and then experienced muscle oedema before finally transformed into an oral mucosa-like appearance at about 60 days after operation. CONCLUSION: Myofascial iliac crest flap is a good option for reconstruction of combined oral mucosa-mandibular defects because of its excellent bone and oral mucosa matches.
